[0019] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0020] Reference Figure 1-Figure 4 A hook mechanism includes a positioning member 1, a control knob 2, a hook 3, and an elastic member 4; the positioning member 1 is provided with a contraction groove 13, two first holes 11 communicating with both ends of the contraction groove 13, and a second hole 12 communicating with one side of the contraction groove 13; the control knob 2 passes through the second hole 12, one end of the control knob 2 is exposed outside the positioning member 1, and the other end of the control knob 2 is located in the contraction groove 13. There are two hooks 3, both of which pass through the first hole 11, one end of the hook 3 is exposed outside the positioning member 1, and the other end of the hook 3 is located in the contraction groove 13; the elastic member 4 is located in the contraction groove 13, the two ends of the elastic member 4 are respectively connected to the hooks 3 on both sides, and one side of the elastic member 4 is connected to the control knob 2; wherein, rotating the control knob 2 drives the elastic member 4 to rotate, thereby driving the hook 3 to move in the first hole 11, realizing the extension and retraction of the hook 3.

[0021] The end of the hook 3 exposed from the first hole 11 is a sloped structure to facilitate the smooth insertion of the product to be tested. The elastic member 4 is specifically a spring.

[0022] By rotating the control knob 2, the elastic member 4 rotates, and the rotation of the elastic member 4 drives the hook 3 to move in the first hole 11, thereby achieving the extension and retraction of the hook 3. This solves the problem that the hook 3 of the detection tool 5 is designed as a fixed structure, making it difficult to remove the product and damaging the product, resulting in scrapping.

[0023] In some embodiments, the first hole 11 and the second hole 12 are perpendicular to each other. This allows for vertical contact between the control knob 2 and the elastic member 4. This provides greater stability, with the force acting perpendicular to the contact surface, reducing the possibility of the elastic member 4 slipping during rotation. Furthermore, the vertical contact design is simpler, easier to manufacture and maintain, and the vertical structure facilitates precise alignment during installation and adjustment.

[0024] In some embodiments, as Figure 3 As shown, the shrinkage groove 13 is a cylindrical structure. The cylindrical structure meets the space requirement of the elastic member 4 when rotating, and on the other hand saves the space occupied by the hook mechanism.

[0025] In some embodiments, as Figure 3 As shown, the hook 3 has a third hole 31 at one end located in the contraction groove 13, and the elastic member 4 has hooks at both ends, each of which extends through the third holes 31 on either side. By connecting the hooks and the third holes 31, the ends of the elastic member 4 are connected to the hooks 3 on both sides. When the elastic member 4 rotates, it lies horizontally in the contraction groove 13, and the hook 3 is pulled by the elastic member 4 to partially retract into the contraction groove 13 and partially retract into the first hole 11.

[0026] In some embodiments, as Figure 3 and Figure 4 As shown, a rotating block 21 is provided on one side of the control knob 2 located at the contraction groove 13 , and the rotating block 21 is used to abut against the elastic member 4 .

[0027] The provision of the rotating block 21 increases the contact area between the control knob 2 and the elastic member 4 , and increases the friction with the elastic member 4 , so that the control knob 2 can more easily drive the elastic member 4 to rotate.

[0028] Preferably, the rotating block 21 is an arc-shaped structure, and the top surface of the rotating block 21 is an arc-shaped surface wrapped toward the elastic member 4. In addition to increasing the contact area between the rotating block 21 and the elastic member 4, the arc-shaped structure also prevents the elastic member 4 from sliding during rotation.

[0029] Furthermore, the rotating block 21 is made of rubber. Rubber has a high coefficient of friction, providing better grip and ensuring good contact between the rotating block 21 and the elastic member 4, thereby effectively transmitting power. Rubber is also highly wear-resistant, maintaining good contact over extended use and reducing maintenance requirements.

[0030] In some embodiments, the end of the control knob 2 exposed from the positioning member 1 is fixedly connected to a handle 22. The provision of the handle 22 increases the gripping area, making the rotation of the control knob 2 more convenient.

[0031] A detection tool 5 includes the hook mechanism of any of the above embodiments.

[0032] The inspection tool 5 is used to inspect the opening size of the product. The opening of the product is used to install the display screen. The opening size is guaranteed by inspection to reduce the occurrence of defective products in the later product assembly.

[0033] How it works:

[0034] Initial state: when there is no external force, the hook 3 is not constrained by the elastic member 4, and one end of the hook 3 extends out of the first hole 11, ready to engage with the product to be tested.

[0035] Engaging process: When the product to be tested approaches the hook 3 and attempts to engage with it, the inclined surface at the front end of the hook 3 guides the product to be tested to be smoothly engaged.

[0036] Unlocking process: The user rotates the control knob 2 to drive the elastic member 4 to rotate until the elastic member 4 is placed horizontally in the shrinkage groove 13 , and the hook 3 is pulled by the elastic member 4 to partially shrink into the shrinkage groove 13 and partially shrink into the first hole 11 .

[0037] Release process: When the control knob 2 is released, the hook 3 located below extends outward from the first hole 11 due to gravity, and the elastic member 4 returns to its original upright state, pushing the upper hook 3 back to the extended state, ready for the next engagement.
