Generally, it is fixed to the crossarm with fasteners. Since the cable clamp has screw holes for fixing, the crossarm also needs to be punched with corresponding holes to achieve the purpose of fastener fixation.

[0003] However, if the installation position is to be changed, the crossarm needs to be punched again, which will damage the strength and make it easy to break under the influence of external factors.

[0004] Therefore, in view of the shortcomings of the above-mentioned solution in actual production and implementation, it has been revised and improved. At the same time, in the spirit and concept of seeking improvement, with the assistance of professional knowledge and experience, as well as after many ingenuity and experiments, the present utility model was created, and a punch-free cable clamp is provided to solve the above-mentioned problems.

[0010] As a preferred embodiment of a punch-free cable clamp, the clamping mechanism includes two semi-cylinders, springs are arranged in the two semi-cylinders, and limit plates are arranged at both ends of the springs. One end of the limit plate is provided with a connecting rod extending outward, and the extended end is provided with a pressure arm.

[0011] With the above solution, the pressing arm can be extended and retracted under the compression of the spring to better fit the cable, and the entire pressing mechanism is detachable for easy maintenance.

[0012] As a preferred embodiment of the punch-free cable clamp, the semi-cylinders are correspondingly buckled with adjacent semi-cylinders to form a cylinder, and the cylinder is slidably fitted in the limiting ring.

[0013] As a preferred embodiment of the punch-free cable clamp, the limiting disk is located in a semi-cylinder, and a hole is provided in the semi-cylinder corresponding to the connecting rod.

[0014] As a preferred embodiment of the punch-free cable clamp, the shape of the pressure arm matches the cable, and the size of the pressure arm is smaller than the cylinder.
