DETAILED DESCRIPTION

[0024] Example 1

[0025] like Figures 1 to 10 As shown, the utility model discloses a detection auxiliary device, and the technical solution adopted is that the bottom box 1 in this embodiment is a box with drawers that can be used to store parts, and two groups of support rods 2 are arranged on the top surface, which are used to adjust the height of multiple groups of support members 11; the support member 2 is provided with a lifting groove 201 on the outer wall, and the teeth 3 are arranged inside, each lifting groove 201 is only arranged on a single arm, and the inlet groove 801 on the positioning block 8 is composed of a circle and a rectangle, and has a flask-like structure, and its inlet part is provided with a chamfer, the purpose is to facilitate the installation of the gear 9 with a connecting shaft 10 on the end face, the connecting shaft 10 is rotatably connected to the circular part, and the outer wall of the positioning block 8 is slidably connected to the lifting groove 201, and the gear 9 and the teeth 3 are meshed with each other, thereby completing the installation of the structure.

[0026] In order to drive the positioning block 8 in the above structure to rise and fall, the connecting plate 4 is connected to the positioning block 8 by bolts, and the end of the connecting plate 4 is also connected to the support member 11 by bolts. The support member 11 is a U-shaped member, and the opposite surface formed by the connecting plate 4 is slidably connected to the support rod 2, so as to fit tightly to avoid looseness.

[0027] A through hole 401 is provided on the connecting plate 4, and a rotating shaft 6 is rotatably connected in the through hole 401. A hexagonal connecting block 7 is provided at the inward end of the rotating shaft 6. The connecting block 7 is adapted to the connecting groove 1001 on the connecting shaft 10. Therefore, when the handle 5 is rotated, the gear 9 is driven to rotate through the rotating shaft 6 and the connecting block 7, thereby achieving the purpose of lifting and lowering the support member 11. Compared with the prior art, its structure is convenient, fast and stable.

[0028] In order to prevent the rotating shaft 6 from falling off from the through hole 401, a telescopic groove 601 is provided on the outer wall of the rotating shaft 6, and a spring 602 and a limit block 603 are installed in the telescopic groove 601. A limit groove 402 corresponding to the limit block 603 is provided on the inner wall of the through hole 401, and the limit groove 402 is annular, thereby realizing the position fixation of the above structure.

[0029] The support member 11 is provided with a ring hole 1101 for installing and placing some parts and the like.

[0030] The working principle of the utility model is as follows: by rotating the handle 5, the handle 5 drives the rotating shaft 6 to rotate, and then drives the connecting block 7 at the end of the rotating shaft 6 to rotate, and the connecting block 7 cooperates with the connecting groove 1001 on the connecting shaft 10, thereby driving the connecting shaft 10 to rotate in the inlet groove 801 of the positioning block 9, and then the gear 9 and the teeth 3 in the lifting groove 201 engage with each other, driving the positioning block 8 to rise and fall in the lifting groove 201, thereby driving the connecting plate 4 and the support member 11 to rise and fall, so as to adjust the height between the support member 11 and the bottom box 1.

[0031] When the outward stretching force of the user is greater than the force of the spring 602 , the limit block 603 moves downward and retracts into the telescopic slot 601 , thereby releasing the limit between the rotating shaft 6 and the limit slot 402 , and two-thirds of the limit block 603 is located in the telescopic slot 601 .

[0032] The mechanical connection involved in the present utility model is a common means used by those skilled in the art, and technical inspiration can be obtained through a limited number of tests, which belongs to common knowledge.

[0033] Components not described in detail herein are prior art.
