    • DETAILED DESCRIPTION OF THE INVENTION
  • Referring to the drawings and initially to FIGS. 1-6, a display rack (20) in accordance with a first embodiment of the present invention is used for mounting a ratchet wrench (10). The ratchet wrench (10) includes a handle (100) having a drive head (11) disposed in one end thereof and a neck portion (12) defined in the handle (100) near the drive head (11). The drive head (11) of the ratchet wrench (10) has a square drive stud (110) extending therefrom for driving a socket (not shown) in a single direction.
  • The display rack (20) of the ratchet wrench (10) comprises a main body (21), a mounting portion (211) mounted on the main body (21) to allow passage of the drive stud (110) of the ratchet wrench (10) and a peripheral wall provided with a plurality of locking portions (212) urged on corners of the square drive stud (110) of the ratchet wrench (10), and a holder (22) mounted on the main body (21) and urged on the neck portion (12) of the handle (100) of the ratchet wrench (10).
  • The main body (21) has a first end formed with a hanging portion (210) for hanging the main body (21). The mounting portion (211) in mounted on a mediate portion of the main body (21) and is preferably a through hole. Preferably, the main body (21) is integrally formed with the mounting portion (211).
  • Preferably, the mounting portion (211) is integrally formed with the locking portions (212) which are extended radially inward therefrom. In addition, the peripheral wall of the mounting portion (211) is provided with a plurality of recessed retaining portions (213) mounted between the locking portions (212). Preferably, the mounting portion (211) is integrally formed with the retaining portions (213).
  • With reference to FIGS. 3 and 4, when the square drive stud (110) of the ratchet wrench (10) is inserted into the mounting portion (211) of the display rack (20), the locking portions (212) are urged on the corners of the square drive studs (110) of the ratchet wrench (10) to retain the square drive stud (110) of the ratchet wrench (10) in the retaining portions (213) closely, so that the square 110) of the ratchet wrench (10) is secured on the mounting portion (211) and cannot be rotated relative to the main body (21) of the display rack (20).
  • The holder (22) has one end pivotally connected to a second end of the main body (21) and has an inside formed with a presage (220) to allow passage of the neck portion (12) of the handle (110) of the ratchet wrench (10). Preferably, the passage (220) of the holder (22) has a side having two ends each formed with an limit portion (221) to limit a further movement of the handle (100) of the ratchet wrench (10) when testing the ratchet function of the ratchet wrench (10).
  • In such a manner, the neck portion (12) of the handle (100) is movable in the passage (220) of the holder (22) between the two limit portions (221) of the passage (220), so that drive head (11) of the ratchet wrench (10) is rotatable relative to the main body (21) of the display rack (20). As a result, the buyer can test the rotation angle and the ratchet function of the drive stud (110) of the ratchet wrench (10) in the display place without detaching the ratchet wrench (10) from the display rack (20). It is a convenient design for buyer to selective a suitable ratchet wrench in the display place, such as a market.
  • With reference to FIG. 7, each of the locking portions (212) has a reduced neck portion to enhance the elasticity of each of the locking portions (212).
  • Accordingly, the main body (21) of the display rack (20) is integrally formed with the mounting portion (211), the locking portions (212) and the retaining portions (213), so that the display rack (20) has a simplified construction, thereby decreasing costs of fabrication. In addition, the locking portions (212) are urged on the corners of the square drive head (110) of the ratchet wrench (10) to retain the square drive head (110) of the ratchet wrench (10) in the retaining portions (213) closely, so that the drive stud (110) of the ratchet wrench (10) is secured on the mounting portion (211) of the display rack (20) rigidly and stably. Further, the square stud (110) of the ratchet wrench is closely secured on the mounting portion (211) and the cannot be rotated relative to the main body (21) of the display rack (20), so that the drive head (11) of the ratchet wrench (10) is rotated relative to the main body (21) of the display rack (20) to test the rotation angle and the ratchet function of the square drive stud (110) of the ratchet wrench (10) exactly. Further, the passage (220) of the holder (22) includes a side having two ends each formed with a limit portion (221) to increasing the testing travel of ratchet wrench (10), so that the rotation angle and the ratchet function of the square drive stud (110) of the ratchet wrench (10) is tested more exactly.
  • With reference to FIG. 8, the display rack (20) further comprises an attachment (214) detachably mounted on the main body (21) and integrally formed with the mounting portion (211), the locking portions (212) and the retaining portions (213). The main body (21) is formed with a positioning hole (216) for mounting the attachment (214) and two opposite locking holes (217) located beside the positioning hole (216). The attachment (214) has a periphery formed with two opposite locking stubs (215) each locked in a respective one of the two opposite locking holes (217) of the main body (21), so that the attachment (214) is secured on the main body (21) closely.
  • With reference to FIG. 9, the holder (22A) is directly detachably engaged to the main body (21) for increasing the testing travel of ratchet wrench (10).
  • Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
