[0013] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0014] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be selected to be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments. Example

[0015] This utility model provides a circuit breaker auxiliary switch pin installation device, including a pin feeding mechanism, a pin retrieving mechanism, and a pin 1. The pin feeding mechanism includes a pin feeding handle 2 and a pin feeding rod 3, with the handle 2 and rod fixedly connected. The pin retrieving mechanism includes a sleeve 4 and a spring 5. The inner wall of the sleeve 4 has a retaining protrusion 6, and the spring 5 is disposed inside the sleeve 4 with one end abutting against the protrusion 6. The pin feeding rod 3 passes through the spring 5 and is fixedly connected to the pin 1, with the other end of the spring 5 abutting against the pin 1. In this embodiment, the sleeve 4 is designed to be 15mm long, with an outer diameter of 2.5mm and an inner diameter of 2.1mm, and the spring is 7.5mm long and has an outer diameter of 2mm.

[0016] The front end of the pin 1 is provided with a boss 7, and the outer diameter of the sleeve 4 is consistent with the diameter of the boss 7. Specifically, the pin 1 has a diameter of 2mm and a length of 7mm, the boss 7 is 2mm away from the front end face, has a diameter of 2.5mm, and a thickness of 1mm.

[0017] The cam 6 is located at a position 2 / 3 of the tube length from the end of the sleeve 4 closest to the pin 1.

[0018] The needle feeding rod 3 and the insertion pin 1 are fixed together by welding. Specifically, the needle feeding rod is a metal wire with a diameter of 0.8 mm and a length of 20 mm.

[0019] Working principle: Hold the needle feeding handle 2 and push the needle feeding rod 3 to insert the needle 1 into the needle insertion hole of the auxiliary contact mechanism. When the locking spring of the auxiliary contact mechanism locks the needle 1, the needle feeding work of the auxiliary contact needle is completed. At this time, there is a certain distance between the boss 7 of the needle 1 and the front end face of the sleeve 4, which is the locking gap. The needle removal process is to push the sleeve 4 towards the needle 1. When the sleeve 4 is pushed to abut the boss 7, the locking gap is zero, which forces the locking spring of the auxiliary contact mechanism to open. The spring squeezes the outer wall of the sleeve 4. Then pull the needle feeding handle 2 to move away from the needle insertion hole of the auxiliary contact mechanism to remove the needle 1.

[0020] In addition to the preferred embodiments described above, there are other embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection claimed by this utility model.
