A sliding groove 120 is provided at the bottom of the wire clamp housing 1, an elliptical hole 115 is provided on the first extrusion block 17, and a rotating groove 116 is provided on the second extrusion block 18. A screw 117 is inserted in the sliding groove 120, and a pair of nuts 118 are threaded on the screw 117, and a gasket 119 is sleeved on the screw 117;

[0025] The first extrusion block 17 is cylindrical and has an arc-shaped extension on one side, the second extrusion block 18 is C-shaped and has an extension on the outside, the C-shape of the second extrusion block 18 fits the cylindrical shape of the first extrusion block 17, the connecting block 114 is located on the inner side of the C-shape, the connecting block 114 is T-shaped, the C-shaped groove 113 is an arc-shaped inverted T-shaped groove, the screw 117 passes through the elliptical hole 115, the disc 19 passes through the horizontal square box 16, the round rod 14 is located in the center of the rectangular box 13, the round rod 14 passes through the slider 15, the round rod 14 is located in the middle of the spring 112, the slider 15 passes through the rectangular box 13, and the screw 117 passes through the slide groove 120.

[0026] In the specific implementation process, Figure 2 and Figure 3 As shown, first screw the nut 118 to the top of the screw 117, and the elastic force of the spring 112 in the rectangular box 13 pushes the slider 15 to the top of the rectangular box 13, and the slider 15 drives the disc 19 to move upward through the horizontal box 16, and the disc 19 drives one end of the first extrusion block 17 to move upward, and the first extrusion block 17 drives one end of the second extrusion block 18 to move upward through the C-shaped groove 113 and the connecting block 114, and the first extrusion block 17 and the second extrusion block 18 drive the arc clamping block 111 to move toward the middle of the wire clamp housing 1, and the copper stranded wire passes through the gap between the wire clamp housing 1 and the arc clamping block 111 into the arc groove 11, and the nut 118 is tightened downward, and the nut 118 squeezes the gasket downward through the screw 117 119, the gasket 119 squeezes the first extrusion block 17 and the second extrusion block 18 downward, and the first extrusion block 17 and the second extrusion block 18 drive the arc clamping block 111 to squeeze the copper strands in the arc groove 11 to both sides to squeeze and fix them. A pair of nuts 118 can reduce looseness caused by shaking, and the gasket 119 can make the pressurized force more uniform. When encountering copper strands of different sizes, the first extrusion block 17 and the second extrusion block 18 can be moved to be located between the two copper strands, so that they are fixed more firmly. Through the coordinated use of the C-shaped groove 113, the connecting block 114, the rectangular box 13, the slider 15, the horizontal box 16 and the disc 19, the device forms a whole and does not need to be assembled when in use.

[0027] Embodiment 2: In embodiment 1, there is still a problem that when the nut is tightened for fixing, the screw may rotate along with it, resulting in an unstable installation. Therefore, based on embodiment 1, this embodiment also includes:

[0029] In the specific implementation process, Figure 4As shown, when the nut 118 rotates, the movable groove 21 on the limiting block 2 causes the screw 117 to be stuck in the movable groove 21, so that when the nut 118 is rotated, the screw 117 will not be driven to rotate together, and when fixing, it can also prevent the screw 117 from rotating with the nut 118, so that it can be better fixed and clamped. Through the coordinated use of the limiting block 2 and the movable groove 21, the screw 117 can be limited when the nut 118 rotates to prevent the screw 117 from rotating, and the installation will not be unstable due to the rotation of the screw 117.

The disc 19 drives one end of the first extrusion block 17 to move upward. The first extrusion block 17 drives one end of the second extrusion block 18 to move upward through the C-shaped groove 113 and the connecting block 114. The first extrusion block 17 and the second extrusion block 18 drive the arc clamping block 111 to move toward the middle of the wire clamp housing 1. During installation, the copper stranded wire is passed through the gap between the wire clamp housing 1 and the arc clamping block 111. Insert the arc groove 11, tighten the nut 118 downward, the nut 118 presses the gasket 119 downward through the screw 117, the gasket 119 presses the first extrusion block 17 and the second extrusion block 18 downward, the first extrusion block 17 and the second extrusion block 18 drive the arc clamping block 111 to squeeze the copper strands in the arc groove 11 to both sides to squeeze and fix them, a pair of nuts 118 can reduce looseness caused by shaking, the gasket 119 can make the pressure more uniform, when encountering copper strands of different sizes, the first extrusion block 17 and the second extrusion block 18 can be moved to be located between the two copper strands, and fixed more firmly;

[0032] Step 2: When the nut 118 rotates, the screw 117 is stuck in the moving groove 21 due to the moving groove 21 on the limiting block 2, so that when the nut 118 is rotated, the screw 117 will not be driven to rotate together, and when fixing, the screw 117 can be prevented from rotating together with the nut 118, so that it can be better fixed and clamped;

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
