Specifically, when the fixture 1 needs to be fixed to an insulator, the first and

second clamp clips

11 and 12 may be sleeved on the insulator, and then the first and second clamp clips 13 may be fastened together to fix the fixture 1 to the insulator.

Furthermore, the first clamp 11 and the second clamp 12 are provided with ear plates on both sides, and the first fastener 13 can be used for fixing the two ear plates.

Specifically, both sides of the first clamp 11 and the second clamp 12 are provided with protruding ear plates, through holes are formed in the ear plates, and the first fastening member 13 can be inserted into the through holes, so that the first clamp and the second clamp are fixedly connected. First fastener 13 in this embodiment can be cam locker, has the convenient advantage of locking and dismantlement, and fixed efficiency can very big improvement.
