The length of the ground wire 600 is reduced, so that the locked ground wire 600 cannot be hung, which is equivalent to locking the ground wire 600 and cannot be used, and when the ring buckle ground wire lock is unlocked, the length of the ground wire 600 meets the hanging requirement and can be hung.
Of course, the first pins 401 may be made of an insulating material, and a first conductive portion is disposed on a surface of one side of the first conductive pins 404 facing the first conductive pins; in the initial state, at least one of the two first conductive pins 404 is in contact connection with the surface of the first pin 401, and at this time, the two first conductive pins 404 are in a non-conductive state; when the first ground wire fixing clip 200 is assembled on the lock body 100 in a locking manner, the two first conducting pins 404 are in contact connection with the first conductive part on the first pin 401 after the axial movement, and at this time, the two first conducting pins 404 are in a conducting state; the second pins 501 may also be made of an insulating material, and a second conductive portion is disposed on a surface of one side of the second conductive pins 504 facing the two second conductive pins; in the initial state, the two second conductive pins 504 are in contact connection with the second conductive portion on the second pin 501, at this time, the two second conductive pins 504 are in a conductive state, and when the first ground wire fixing clip 200 is assembled on the lock body 100 in a locking manner, at least one of the two second conductive pins 504 is in contact connection with the surface of the second pin 501 after the axial movement, at this time, the two second conductive pins 504 are in a non-conductive state.

In this way, the stability of the axial movement of the first elastic pin 401 and the second elastic pin 501 can be further improved, thereby ensuring the accurate switching control of the conducting and non-conducting states of the two first conducting elastic pins 404 and the two second conducting elastic pins 504
Of course, raised guide blocks may be provided on the surfaces of the first elastic pin 401 and the second elastic pin 501, and correspondingly, axially provided guide grooves may be provided on the inner side surfaces of the first concave cavity 405 and the second concave cavity 505; during assembly, the guide blocks of the first elastic pin 401 and the second elastic pin 501 can be respectively clamped in the guide groove of the first concave cavity 405 and the guide groove of the second concave cavity 505 in a back-and-forth movable manner.
