[0019] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0020] like Figure 1 , Figure 3 and Figure 5 As shown, an embodiment of the present application provides an inspection auxiliary fixture, including a base 1, on which a fixed block 2, a contour fixing portion 3 and a hand-crank assembly 4 are arranged, the fixed block 2 is fixedly mounted at one end of the base 1, the contour fixing portion 3 includes a contour portion 31 and a rotating portion 32, the radius of the contour portion 31 at one end away from the rotating portion 32 is smaller than the radius of the other end of the rotating portion 32, the contour portion 31 is used to fix the product, the rotating portion 32 passes through the fixed block 2 and is connected to the hand-crank assembly 4, the rotating portion 32 rotates with the fixed block 2, and the hand-crank assembly 4 is used to rotate the rotating portion 32 and the contour portion 31.

[0021] Specifically, the base 1 is in a square shape, and a fixed block 2 is provided at one end of the base 1. The fixed block 2 is provided with a circular through hole for the rotating portion 32 of the profiling fixed portion 3 to pass through, and the rotating portion 32 is rotatably matched with the fixed block 2. The radius of the rotating portion 32 of the profiling fixed portion 3 is greater than the radius of the profiling portion 31, and the radius of one end of the profiling portion 31 close to the rotating portion 32 is greater than the radius of the other end of the profiling portion 31. The overall size of the profiling portion 31 is compatible with the non-standard plastic fastener 5. The hand crank assembly 4 is fixedly connected to one end of the rotating portion 32 away from the profiling portion 31. The hand crank assembly 4 can drive the rotating portion 32 to rotate, and the rotating portion 32 drives the profiling portion 31 to rotate.

[0022] The open end of the non-standard plastic fastener 5 is passed through the profiling portion 31 so that the non-standard plastic fastener 5 is fastened on the profiling portion 31. One end of the non-standard plastic fastener 5 with three circular through holes corresponds to the micrometer in the prior art. Then, the rotating portion 32 is rotated by the hand crank assembly 4, and the rotating portion 32 drives the profiling portion 31 to rotate, and the profiling portion 31 drives the non-standard plastic fastener 5 to rotate, so that the micrometer measures the centrality of the three circular through holes on the non-standard plastic fastener 5.

[0023] In the above structure, the non-standard plastic fastener 5 is fastened to the profiling portion 31 by providing a profiling fixing portion 3 adapted to the non-standard plastic fastener 5. This arrangement not only improves the fixing effect of the non-standard plastic fastener 5, but also prevents the non-standard plastic fastener 5 from loosening and falling during the rotation process.

[0024] like Figure 2 As shown, in one embodiment, the hand crank assembly 4 of the inspection auxiliary fixture includes a hand crank lever 41 and a bolt assembly 42, and a connecting hole 321 is provided at one end of the rotating part 32 away from the profiling part 31, and one end of the hand crank lever 41 is fixedly connected to the connecting hole 321 of the rotating part 32 through the bolt assembly 42, and the hand crank lever 41 is used to drive the rotating part 32 and the profiling part 31 to rotate.

[0025] Specifically, one end of the hand crank 41 passes through the connecting hole 321 of the contouring part 31, and then the bolt assembly 42 fixes one end of the hand crank 41 to the rotating part 32. The other end of the hand crank 41 can drive the rotating part 32 to rotate, and the rotating part 32 drives the contouring part 31 to rotate.

[0026] This arrangement facilitates the rotation of the contour fixing portion 3 by shaking the hand crank 41 , thereby facilitating the measurement of the non-standard plastic fastener 5 on the contour fixing portion 3 .

[0027] like Figure 2 As shown, in one embodiment, the hand crank 41 of the inspection auxiliary fixture is set to be L-shaped.

[0028] Specifically, the L-shaped hand crank 41 is provided, so that it is convenient for a person to grasp the hand crank 41 and rotate it, making the hand crank 41 convenient and simple to operate.

[0029] like Figure 3 and Figure 4 As shown, in one embodiment, the interior of the profiling portion 31 and the rotating portion 32 of the inspection auxiliary fixture also includes a fixed core 33, and the fixed core 33 includes a small head end 331, a profiling section 332, a fixed section 333 and a large head end 334 in sequence. The radius of the small head end 331 is smaller than the radius of the large head end 334, and the radius of the end of the profiling section 332 connected to the small head end 331 is larger than the radius of the end of the profiling section 332 connected to the fixed section 333. The small head end 331 and the profiling section 332 are located inside the profiling portion 31, and the fixed section 333 and the large head end 334 are located inside the rotating portion 32.

[0030] Specifically, a fixing core 33 is arranged in the profiling fixing part 3, a small end 331 of the fixing core 33 is connected to the profiling section 332, the profiling section 332 is connected to the fixing section 333, the fixing section 333 is connected to the large end 334, wherein the radius of the small end 331 is smaller than the radius of the large end 334, and the radius of the profiling section 332 close to the small end 331 is smaller than the radius of the other end of the profiling section 332. This structure is mainly arranged for the structural shape of the profiling fixing part 3 and the non-standard plastic fastener 5.

[0031] This arrangement not only enhances the toughness of the contour fixing portion 3, but also increases the service life of the fixture.

[0032] like Figure 4 As shown, in one embodiment, the small end 331, the contoured section 332, the fixed section 333 and the large end 334 of the fixed core 33 of the inspection auxiliary fixture are integrally formed.

[0033] Specifically, the small end 331, the profiling section 332, the fixing section 333 and the large end 334 are integrally formed. This arrangement effectively improves the toughness of the profiling fixing portion 3 and also increases the service life of the fixture.

[0034] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
