[0016] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0017] Please refer to Figure 1 - Figure 4 The present application provides a technical solution:

[0018] The positioning mechanism for the inner circle product comprises a reference base 1, the reference base 1 is made of a bottom plate and a mounting column through welding, and a mounting groove for mounting a profiling positioning tongue piece 2 is formed in the middle of the top surface of the mounting column, a circular hole is symmetrically formed in the mounting groove, a bearing is mounted in the circular hole, and a positioning pin 3 is mounted in the bearing, and the positioning pin 3 is in a vertical state with the mounting groove, so as to facilitate the rotation of the profiling positioning tongue piece 2; the profiling positioning tongue piece 2 is arranged on the outer wall of the positioning pin 3, and the profiling positioning tongue piece 2 is fixed on the outer wall of the positioning pin 3 through clamping; a spring 4 is arranged between the bottoms of the profiling positioning tongue pieces 2, the ends of the spring 4 are fixedly connected to connecting plates 203, threaded holes are formed in the connecting plates 203, annular plates are welded to the ends of the spring 4, and bolts matched with the threaded holes are arranged in the annular plates, so that the spring 4 can be fixed between the two connecting plates 203 through the bolts, the connecting plates 203 are pressed, the arc-shaped plate 202 is pressed, and the inner circle product is further positioned; and the spring 4 is in a compressed state in a normal state, the profiling positioning tongue piece 2 is always pressed, and the inner circle product is fixed, so that the operation is simple and convenient, and the efficiency of fixing the inner circle product is improved.

[0019] In the utility model, the profiled positioning tongue piece 2 includes the arc plate 202, the profiled positioning tongue piece 2 top is obliquely fixed with the inclined plate 201, and the inclined plate 201 is fixed with the arc plate 202 through the welding mode, and the inclined direction of the inclined plate 201 is towards the outside of the mounting groove, and an inverted eight-shaped area is formed between the two inclined plates 201, so that the inner circle product enters between the two arc plates 202, thereby facilitating the fixing of the inner circle product, and the operation is simple, convenient and improves the efficiency of the fixing of the inner circle product.

[0020] Working principle: when the utility model is used, the inner circle product is placed between the two inclined plates 201, then the inner circle product is extruded downwards to make the two inclined plates 201 open, and then the arc plate 202 is driven to rotate, so that the inner circle product enters between the two arc plates 202, the downward pressure disappears, then the axial force of the spring 4 extrudes the connecting plate 203, so that the arc plate 202 rotates, and the clamping force between the two arc plates 202 realizes the clamping and fixing of the inner circle product, and the operation is simple, convenient and improves the fixing efficiency of the inner circle product.
