Technical Field

[0001] The invention relates to the technical field of wire spring hole processing, in particular to a shrink-mouth type clamp. Background Art

[0002] The full name of the wire spring jack is single-leaf rotary hyperbolic wire spring jack, which is a high-reliability jack component used on electrical connectors (i.e. connectors). It has low insertion and extraction force, low contact resistance and high reliability. Hyperbolic wire spring jacks are mainly used in connectors for various key equipment.

[0003] In the process of processing the wire spring hole, it is necessary to manually connect the inner sleeve, the front sleeve and the wire. If machine processing is used, a material picking rod is required to cooperate with the device to load and unload the inner sleeve and the front sleeve. However, the material picking rods used in most devices currently have problems of tightness and looseness, because the material picking rod needs to be tightly connected with the front sleeve or the inner sleeve when picking up materials, but needs to be loosened with the inner sleeve or the front sleeve during the unloading process so that the opposite device can pick it up. However, the current material picking rods mostly use sizes that match the inner sleeve and the front sleeve. Therefore, in the process of processing the wire spring hole, the material is often loose or cannot be removed, which is very troublesome. Therefore, a shrink-mouth clamp is urgently needed on the material picking rod to solve the above-mentioned problems. Summary of the invention
