However, the cable clamp has the following technical problems: the existing cable clamp needs a spanner or a hydraulic clamp installation tool, and a large amount of manpower and material resources are consumed in construction.

Disclosure of Invention

The invention aims to provide a portable wire clamp to solve the technical problem that a cable clamp in the prior art is inconvenient to use.

In order to achieve the above object, the technical solution adopted by the present invention is to provide a portable wire clamp, including at least a pair of clamping cover plates, the pair of clamping cover plates are rotatably connected through a rotating shaft, at least one end of the pair of clamping cover plates is formed with a clamping groove for clamping a wire, one end of the pair of clamping cover plates is further connected through a fastener, at least one end of the fastener is connected with a clamping structure; the clamping and fixing structure comprises a handheld piece, one end of the handheld piece is rotatably connected onto the fastener through a connecting pin shaft, the outer wall of the handheld piece is suitable for being directly or indirectly abutted against the clamping cover plate, and the rotating center of the handheld piece is eccentrically arranged relative to the appearance center of the handheld piece.

Furthermore, one end of the fastener is connected with one of the clamping cover plates in one pair through the clamping structure, and the other end of the fastener is connected with the other clamping cover plate in one pair through a threaded structure.

Furthermore, one end of each of the pair of clamping cover plates is provided with a first clamping groove for clamping a wire, the other end of each of the pair of clamping cover plates is provided with a second clamping groove for clamping the wire, and the rotating shaft is positioned between the first clamping groove and the second clamping groove.
