is arranged at the rear side of the pin, a mode that a lead is inserted into a lead groove to contact with the joint to connect a device with external equipment is generally adopted in the prior art, lead grooves 4 are uniformly arranged on the upper side wall and the lower side wall of the base, one ends of the lead grooves far away from an opening are communicated with the rear part of the slot, the lead grooves are arranged in the base, the opening at one end is communicated with the outside for the lead to be inserted into, the other end is communicated with the slot, when, the plug pin and the connector are arranged in the slot, the connector is arranged at the rear part of the plug pin and extends into the wire guide groove, the front end of the wire guide groove is communicated with a thread groove, an internal thread is arranged on the side wall of the thread groove, an opening at one end of the thread groove is communicated with the outside, a threaded rod extends into the thread groove, the other end of the thread groove is communicated with the wire guide groove, the threaded rod can extend into the wire guide groove, a threaded rod 5 is connected with the thread in the thread groove in a threaded manner, an external thread is arranged on the side wall of the threaded rod, a handle 6 is arranged at the front end of the threaded rod, the threaded rod and the handle are supported by insulating materials, protruding stripes are arranged on the side wall of the handle, the friction force is increased, the threaded rod can be conveniently held by hand to rotate, the threaded rod can be screwed in and out by rotating the handle, after a lead is inserted, the threaded rod is rotated backwards to reduce the distance between the threaded rod and the side wall of the rear part of the lead groove, the threaded rod continuously extrudes the lead, the lead is fixed in the lead groove, when the lead needs to be taken out, the threaded rod is rotated forwards to loosen the lead, and then the lead is taken out, the rear end of the threaded rod is in threaded connection with a thimble block 7, the rear end of the thimble block is provided with a thimble 8, the thimble
