Further, the specific second preset distance needs to be configured according to the actual use condition, which is not required in this embodiment.

In this embodiment, during the process of disassembling the quick-insertion jig, the rod body 9 can be pushed to move axially, when the axis of the accommodating hole is coincident with the axis of the through hole 24, an operator uses a tool, such as a needle body, to extend from the through hole 24 and abut against one end of the positioning pin 26 located in the accommodating hole, and pushes the needle body along the direction towards the positioning pin 26, so that the positioning pin 26 is separated from the accommodating hole; therefore, in this embodiment, the through hole 24 is formed in the sleeve, so as to facilitate insertion of the needle body, and the positioning pin 26 is pushed out of the accommodating hole along the radial direction of the rod body 9, so that the technical problems of radial deformation, difficult clamping and the like of the positioning pin 26 caused by clamping and pulling the positioning pin 26 by using tools such as tweezers and pliers are avoided.

Preferably, in the quick insertion checking fixture of the embodiment, arc transition surfaces are arranged at the joint of each part and at the right angle of each single part in processing, so that scraping on the quick insertion port in use is avoided, and the quick insertion port is protected in detection.

The foregoing examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
