Other objects, advantages and features of the present invention will become apparent from

The preferred structural aspects of the present invention will now be described by way of example only and not by way of limitation, and reference to the accompanying drawings. The tool head set 10 includes a body 12, a plurality of tool heads 14, two positioning devices 16, and two operating members 18.

The seat body 12 includes two side faces 20, and each side face 20 is combined with a side plate 22, and the height and length of each side plate 22 are slightly larger than the height and length of the seat body 12, but it is understood that the two side plates 22 can be integrally coupled to the two side faces 20. . The base 12 further includes a first surface 24 and a second surface 25 opposite to each other, and a first end 26 and a second end 27 separated in a lengthwise direction. The two side plates 22 are respectively provided with a coupling hole 28 for providing a shaft 29 to pass through, and a through hole 30 for providing one of the operating members 18 to pass therethrough. The two shafts 29 are individually spaced apart from the first and second surfaces 24, 25 of the body 12. The first end 26 of the first surface 24 of the body 12 and the second end 27 of the second surface 25 individually define a recess 32,33. Furthermore, a first groove 26 of the first surface 24 of the seat body 12 and a second end 27 of the second surface 25 have a groove 34, 35, and each groove 34, 35 extends between the two side plates 22.

In the present embodiment, three tool heads 14, a positioning device 16, and an operating member 18 are separately mounted on the first surface 24 and the second surface 25 of the base 12. In another embodiment (see FIG. 7), the tool head set 10 includes only three tool heads 14, a positioning device 16, and an operating member 18 mounted on the first surface 24 of the body 12. Since the first surface 24 and the tool head 14, the positioning device 16, and the operating member 18 on the second surface 25 are the same or similar structures, only the tool head 14, the positioning device 16, and the operating member on the first surface 24 will be described below. 18 to explain.

Each of the tool heads 14 is a hexagonal drive head of a different size, however, each of the tool heads 14 can be a one-line, plum-type, or cross-type drive head. Each of the tool heads 14 includes a coupling end 36 and a driving end 37 that can be inserted into the bearing hole of the screw head. The coupling end 36 has an annular outer surface 38 and a shaft hole 39. The three tool heads 14 are separated by a collar 40 and are arranged between the two side panels 22 along the length. The shafts 29 extend through the coupling holes 28 of the two side plates 22 and the shaft holes 39 of the tool heads 14 such that the tool heads 14 are rotatable relative to the seat body 12 about an axis defined by the shafts 29. Furthermore, the outer surface 38 of the joint end 36 of each tool head 14 is provided with a plurality of positioning grooves 41 spaced along the peripheral direction.

A positioning device 16 mounted on the first surface 24 of the body 12 is positioned within the recess 32 and between the first surface 24 and the tool head 14. The positioning device 16 includes a plate body 42 , a plurality of positioning beads 43 , and a spring piece 44 . The plate body 42 is secured to the base 12 by fasteners 46 such as screws. The outer end of the plate body 42 is located on the groove 34 and has a plurality of perforations 48. Each of the positioning beads 43 is received in one of the perforations 48. The elastic piece 44 is mounted between the plate body 42 and the first surface 24 of the base 12 and includes a plurality of spaced apart elastic arms 50, each of the elastic arms 50 abutting against the inner side of one of the positioning beads 43 such that the outermost portion 52 of the positioning bead 43 The perforations 48 are raised and abut against the outer surface 38 of the joint end 36 of the tool head 14. In the present embodiment, the positioning device 16 further includes a pad 54 mounted between the tab 44 and the first surface 24 of the base 12 such that the tab 44 is spaced from the first surface 24 of the base 12.

The operating member 18 on the first surface 24 of the base 12 is mounted within the groove 34 of the base 12 and is moveable between a first position and a second position. The operating member 18 includes a first section 56 and a second section 58 in which the first section 56 of the operating member 18 is received and abuts against a spring 60. The operating member 18 is normally in the first position, wherein the spring 60 biases the operating member 18 such that the second segment 58 projects out of the side panel 22 for the user to press (see fourth figure). When the second section 58 of the pressing operating member 18 is moved into the seat body 12, the operating member 18 compresses the spring 60 to move to the second position (see Fig. 5). The operating member 18 further includes an inner surface 62 facing the positioning bead 43, and the inner surface 62 is provided with a plurality of grooves 64. When the operating member 18 is in the first position, the number of grooves 64 are offset from the positioning beads 43 such that the positioning beads 43 and the elastic arms 50 abut against the inner surface 62 of the operating member 18 and cannot move toward the operating member 18; On the one hand, when the operating member 18 is in the second position, the number of grooves 64 will be aligned with the positioning beads 43 so that the positioning beads 43 and the elastic arms 50 can move toward the operating member 18, and thus, the tool heads 14 can be wound. The axis defined by the shaft 29 rotates relative to the seat 12.

In use, the tool head set 10 has a plurality of tool heads 14 of different types or sizes and is convenient for the user to carry around. In operation, the body 12 of the tool head set 10 can be used as a handle for the user to hold, and each tool head 14 can assume a variety of different angles relative to the body 12 for operation (see Figure 6). In particular, the operating member 18 is normally in the first position and the outermost portion 52 of each of the positioning beads 43 abuts against one of the positioning grooves 41 of the outer surface 38 of the coupling end 36 of the tool head 14, so that the tool heads The 14 series is rotatably folded into the recesses 32, 33 of the seat body 12. On the other hand, when the second section 58 of the biasing operating member 18 moves the operating member 18 to the second position, the user can rotate the selected size or type of tool head 14 to a desired operating angle (available It is 90 degrees, 135 degrees, 180 degrees, or other angles as shown in the sixth figure). After the tool head 14 is rotated to the desired operating angle and the user releases the force applied to the second section 58 of the operating member 18, the spring force of the spring 60 biases the operating member 18 to the first position, causing the tool head 14 Positioned to provide locking or loosening of the screw. By adjusting and positioning the operating angles of the tool heads 14, the tool heads 14 can meet the requirements of different operating environments, and the user can operate the turning operation more smoothly, and can reduce the tightening or loosening of the workpiece. The power exerted.

A variety of variations and modifications can be made in the spirit of the invention, and obvious substitutions and modifications may be made by those skilled in the art, which are still within the scope of the claimed invention.
