DETAILED DESCRIPTION OF THE INVENTION

Referring to the drawings and initially to Figs. 1-4, a tool display rack 20 in accordance with a first embodiment of the present invention is used for mounting a tool 10. The tool 10 has a drive head 11 and a neck portion 12. The drive head 11 of the tool 10 has a square drive stud 110.
The tool display rack 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 tool 10 and having an inner edge closely urged on a peripheral wall of the drive stud 110 of the tool 10 to produce a contact friction therebetween, and a pressing member 22 pivotally mounted on the main body 21 and urged on the neck portion 12 of the tool 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 is mounted on a mediate portion of the main body 21 and is preferably a through hole having a diameter slightly smaller than a size of the drive stud 110 of the tool 10. Preferably, the main body 21 is integrally formed with the mounting portion 211.
The mounting portion 211 has a peripheral wall provided with a plurality of elastic portions 212 each radially extended outward therefrom. Preferably, each of the elastic portions 212 of the mounting portion 211 is an elongated slit. The peripheral wall of the mounting portion 211 is provided with a plurality of elastically deformable holding portions 213 located between the elastic portions 212. Preferably, the mounting portion 211 is integrally formed with the elastic portions 212 and the holding portions 213.
As shown in Fig. 3, the drive stud 110 of the tool 10 is inserted into the mounting portion 211 of the tool display rack 20. At this time, the mounting portion 211 has a diameter slightly smaller than a size of the drive stud 110 of the tool 10, so that when the drive stud 110 of the tool 10 is inserted into the mounting portion 211 of the tool display rack 20, the drive stud 110 of the tool 10 is urged on the holding portions 213 of the mounting portion 211 to deform the holding portions 213 of the mounting portion 211 As shown in Fig. 4. In such a manner, the deformed holding portions 213 of the mounting portion 211 are urged on the peripheral wall of the drive stud 110 of the tool 10 closely so as to clamp the drive stud 110 of the tool 10 rigidly and stably, so that the drive stud 110 of the tool 10 is secured in the mounting portion 211 and cannot be rotated relative to the main body 21 of the tool display rack 20.
As shown in Fig. 1, the pressing member 22 is pivotally mounted on a second end of the main body 21 and has an inside formed with a passage 220 to allow passage of the neck portion 12 of the tool 10. Preferably, the passage 220 of the pressing member 22 has a side having two ends each formed with an oblique limit portion 221 to limit a further movement of the neck portion 12 of the tool 10.
In such a manner, the neck portion 12 of the tool 10 is movable in the passage 220 of the pressing member 22 between the limit portions 221 of the passage 220, so that the drive head 11 of the tool 10 is rotated relative to the main body 21 of the tool display rack 20 to test the rotation angle of the drive stud 110 of the tool 10.
Accordingly, the main body 21 of the tool display rack 20 is integrally formed with the mounting portion 211, the elastic portions 212 and the holding portions 213, so that the tool display rack 20 has a simplified construction, thereby decreasing costs of fabrication. In addition, the holding portions 213 of the mounting portion 211 are deformed and urged on the peripheral wall of the drive stud 110 of the tool 10 closely so as to clamp the drive stud 110 of the tool 10, so that the drive stud 110 of the tool 10 is secured in the mounting portion 211 rigidly and stably. Further, the drive stud 110 of the tool 10 is closely secured on the mounting portion 211 and cannot be rotated relative to the main body 21 of the tool display rack 20, so that the drive head 11 of the tool 10 is rotated relative to the main body 21 of the tool display rack 20 to test the rotation angle of the drive stud 110 of the tool 10 exactly. Further, the passage 220 of the pressing member 22 has a side having two ends each formed with an oblique limit portion 221 to increase the testing travel of the tool 10, so that the rotation angle of the drive stud 110 of the tool 10 is tested more exactly.
