[0060] Through the auxiliary cooperation between the threaded rod 32 and the clamping plate 34, the threaded rod 32 can be rotated clockwise to drive the clamping plate 34 to slide downward and simultaneously drive the tooth block 37 to slide, thereby clamping the plug inserted in the wire slot 14.

[0061] Working principle: after the worker inserts the plug into the inside of the wire slot 14;

[0062] First, the worker rotates the threaded rod 32 at the top end of the protective shell 31 clockwise, which can drive the clamping plate 34 to slide downward and can cause the rack 35 to clamp the plug below.

[0063] Then, the rack 35 and the rotating gear 36 are engaged and connected, which can cause the rotating gear 36 to rotate and be engaged with the tooth block 37, so that the two sets of tooth blocks 37 slide while driving the threaded block 33 to clamp the two sides of the plug.
