The utility model relates to the technical field of wire clamps, and particularly discloses a strain wire clamp which comprises a wire clamp body, a wire duct is arranged on the wire clamp body, a clamping block is movably arranged in the wire duct, and a matching block is fixedly arranged at one end of the clamping block. A mounting block is fixed to one end of the clamping block, positioning grooves are symmetrically formed in one end of the mounting block, positioning blocks which are symmetrically distributed are fixedly arranged at the end of the matching block, the positioning blocks are matched with the positioning grooves, an opening groove is formed in the position, located on one side of the wire groove, of the wire clamp body and communicated with the wire groove, and a protruding block is fixedly arranged at one end of the wire clamp body. And a hanging lug is fixedly arranged on the wire clamp body. According to the strain clamp, the clamping block and the matching block are locked through the bolt, the clamp is used for positioning and fixing, the strain clamp is suitable for actual wire clamping, the working efficiency is improved, the design of the limiting screw rod and the limiting hole is adopted to lock a wire on the strain clamp, the locking force of the strain clamp is guaranteed, the wire fixing and clamping strength is improved, and the strain clamp is convenient to use. And the fixing firmness of the wire is ensured.

The utility model discloses a novel strain clamp, which comprises a clamp main body, the clamp main body is of a cylindrical structure, a steel sleeve is fixed in the clamp main body, a wedge-shaped clamp with a wire slot is sleeved in the steel sleeve, the right end of the wedge-shaped clamp extends outwards, a clamp iron is clamped on the wedge-shaped clamp, a U-shaped hanging ring is fixed at the right end part of the clamp iron, and the U-shaped hanging ring is fixed at the right end part of the clamp iron. The end part of the right end of the wire clamp main body is communicated with a hollow drainage wire clamp, the drainage wire clamp extends downwards, the steel sleeve penetrates through the upper end of the drainage wire clamp, and the upper end of the drainage wire clamp is communicated with the wedge-shaped wire clamp; the beneficial effects are that the wedge-shaped wire clamp and the clamp iron are used for dual fastening, the clamping effect is good, the firm clamping effect can be achieved without large pressure, and the wire clamp main body is provided with the drainage wire clamp, so that wire tapping is very convenient.

The invention discloses an insulator convenient to replace, which comprises an insulating rod, a lockset, a wire clamp and a plurality of umbrella skirts, and is characterized in that the lockset is arranged at the bottom of the insulating rod, the wire clamp comprises an upper clamp and a lower clamp which are both provided with arc-shaped grooves, the upper clamp is rotatably arranged on the lower clamp, and the umbrella skirts are arranged on the insulating rod at intervals; the locking device is used for fixing the rotated upper clamp on the lower clamp; the connecting piece is arranged on the insulating rod, a second cavity and two L-shaped sliding grooves are formed in the connecting piece, and the cavity is communicated with the L-shaped sliding grooves; the connecting device comprises a sliding block, four clamping blocks and a driving device, the sliding block is arranged in the first cavity and the second cavity in a sliding mode, and the driving device is arranged on the external cross arm and can move on the external cross arm to drive the sliding block to move up and down or rotate. Provided is a wire clamp fixing device. According to the invention, when the insulator needs to be replaced, the wire clamp does not need to be disassembled, the insulator can be rapidly replaced, and the insulator can be supported after being damaged.
