The spinning component 7 can move along the axial direction of the transmission gear 8 and transmit coaxially with the transmission gear 8. When the transmission gear 8 rotates, the spinning component 7 can be driven to rotate. On the other hand, the center of the auxiliary fixture 1 and the top of the spinning component 7 form a spiral pair. When the spinning component 7 rotates forward, the spinning component 7 can be assembled with the auxiliary fixture 1 in a threaded manner. On the contrary, when the spinning component 7 rotates reversely, the spinning component 7 can be withdrawn from the auxiliary fixture 1, so that the auxiliary fixture 1 is separated from the spinning component 7.

[0055] In specific use, such as Figure 1 and Figure 2 , the auxiliary fixture 1 is fixedly combined with the detection and positioning element, and the overall disassembly and assembly of the detection and positioning element is realized by disassembling the auxiliary fixture 1. On this basis, a rack 2 is slidably inserted at the front end of the base 3, and the rack 2 is connected to the transmission gear 8 by gear meshing transmission, and the transmission gear 8 is rotatably arranged in the base 3, so that the transmission gear 8 is driven to rotate by the sliding rack 2. The end of the rack 2 is connected to the transmission connecting member 5, and a locking device 6 is installed at the center of the transmission connecting member 5.

Finally, after the base 3 is withdrawn, the detection positioning element can be completely removed by taking out the auxiliary fixture 1.

[0063] In a specific embodiment disclosed in the present invention, Figure 8 The transmission connector 5 includes a connection block 51, a threaded hole 52 and a mounting hole 53. The threaded hole 52 is provided at the center of the connection block 51. In an optional technical solution, the locker 6 is fixed to the connection block 51 by threaded engagement. When in use, the connection block 51 is directly driven to move linearly by pulling the locker 6.

[0064] In another optional technical solution, Fig. 9The locker 6 includes a coupling 61 and a stud 63, wherein the stud 63 and the threaded hole 52 form a spiral pair, and the stud 63 is coaxially connected to the tail end of the coupling 61. A thumbwheel 62 is provided at the head end of the coupling 61, and the thumbwheel 62 drives the stud 63 to rotate, and then the spiral pair between the stud 63 and the threaded hole 52 is used for transmission, and then the connection block 51 is driven to move linearly.

[0065] In this embodiment, the interior of the mounting hole 53 is suitable for inserting fasteners and mounting the rack 2 through the fasteners, and the connecting block 51 is fixedly connected to the end of the push rod 41, and a length scale is provided on the push rod 41 to display the distance of the linear movement of the connecting block 51.
