Suspension clamps are one of the most widely used fittings in power overhead lines. They can be used to hang wires, cables, cables and other cables on a linear tower with a connecting fitting. Since the installation operation of the suspension clamp is mostly for aerial work, whether the installation of the suspension clamp is simple and quick, whether it can satisfy the convenient operation and whether the installation process is labor-saving is an important consideration for its structural design.

In the existing suspension clamps, the structure of the u-shaped clamp groove and the crimping member is used to press and fix the cable. For example, the "suspension clamp" disclosed in the Chinese Utility Model Patent No. CN202183580U (Application No. 201120321391.9), the groove and the pressure plate fix the cable by bolts and nuts. The "suspension clamp" disclosed in the Chinese utility model patent with the authorization bulletin number CN202340107U (application number 201120439831.0) is used to drive the crimping member to press the external cable into the clamping slot. Although the suspension clamps of these structures can fix the cable well, in the high-altitude operation, the assembly process is complicated, and the operator needs to hold the crimping component during the installation and fastening of the cable, but the hand-held crimping component The operation is time consuming and laborious in working at height, and the problem of falling of the crimping member is also prone to occur. Obviously, the suspension clamps of these structures increase the difficulty of operation by aerial workers. In addition, the suspension clamps of these structures are complicated in structure, which leads to complicated processing and reduced production efficiency. Summary of the invention
