In detail, since the fixing portion 6 fixes the worm 4, the fixing portion 6 does not rotate with the worm 4 when the worm 4 rotates, and the fixing portion 6 is connected with the C-shaped guide groove 7, the C-shaped guide groove 7 clamps the C-shaped wire clamp 2, so that the C-shaped wire clamp 2 does not move.
When the cable clamping device is used, a cable is clamped through the clamping mechanism, and the clamping mechanism extends to the cable through the telescopic rod 1 and is placed at a proper position. The telescopic rod 1 is rotated, the worm 4 rotates along with the rotation of the telescopic rod 1, the worm wheel 3 is meshed with the worm 4, and the worm wheel 3 rotates along with the meshing. The worm wheel 3 is directly connected with the push rod 9, the C-shaped wire clamp 2 is installed in a matching mode with the push rod 9, and the screw hole is meshed with the screw rod. When the external screw thread push rod 9 was rotatory, C type fastener 2 can be under the reverse thrust effect of internal screw thread, through C type guide way 7 along push rod 9 axial displacement, make the recess in the C type fastener 2 be close to push rod 9, realize pressing from both sides tight to the cable, until telescopic link 1 no longer rotates and presss from both sides tightly completely, solved the clamping torque that exists among the prior art not enough and lead to the problem of test line contact.
