The first fixing frame 2 is fixedly installed on the bottom surface of the protection box 1, and the right side of the movable wedge block 12 is in contact with the side wall of the first fixing frame 2 through the tensioning spring 16. When the high-voltage line is clamped, the electric telescopic rod 10 is opened to move the base 11 downward, and the high-voltage line is moved upward through the left top surface of the movable wedge block 12. When the high-voltage line moves upward, the movable wedge block 12 is acted upon by the upward moving force, and the movable wedge block 12 will move toward the inside of the base 11, so that the high-voltage line is moved to the top of the movable wedge block 12. A lever 17 is fixedly installed on the bottom surface of the movable wedge block 12. When the high-voltage line is taken out, the lever 17 is pushed to the left end so that the movable wedge block 12 enters the inside of the base 11 to facilitate the removal of the clamped high-voltage line. At the same time, in order to facilitate the installation of the high-voltage line, the high-voltage line can also be placed by pushing the lever 17.

[0018] In this embodiment, Figure 1-4As shown, a lifting seat 4 is slidably connected between the first fixed frame 2 and the second fixed frame 14. The lifting seat 4 is arranged above the moving wedge block 12 and below the protective box 1. A first clamping groove 5 is arranged inside the bottom surface of the lifting seat 4, and a second clamping groove 13 is arranged inside the top surface of the moving wedge block 12. The first clamping groove 5 and the second clamping groove 13 are on the same axial direction. After the high-voltage line enters the moving wedge block 12, it enters the first clamping groove 13. At this time, the moving wedge block 12 is opened by the electric telescopic rod 10, so that the base 11 drives the moving wedge block 12 to move downward, thereby the moving wedge block 12 The distance between the base 11 and the lifting seat 4 is large, so that after the high-voltage line is placed, the electric telescopic rod 10 is used to move the base 11 upward, so that the lifting seat 4 and the moving wedge 12 can clamp the placed high-voltage line, and can clamp it firmly. The bottom surface of the protection box 1 is rotatably connected with a knob 3, and the side wall of the first fixed frame 2 is provided with a moving groove 6. The inside of the moving groove 6 is rotatably connected with a screw rod 7. The upper end of the screw rod 7 is fixedly connected with the knob 3 by passing through the inside of the protection box 1. The right side wall of the lifting seat 4 is fixedly installed with a slider 8, which is slidably connected to the inside of the moving groove 6 and is threadedly sleeved on the rod wall of the screw rod 7. According to the diameter of the clamped high-voltage line, the knob 3 is rotated to rotate the screw rod 7, so that the slider 8 can drive the lifting seat 4 to adjust upward, which can prevent the lifting seat 4 and the moving wedge 12 from causing damage to the high-voltage line while clamping and tightening it, so that the clamping force is moderate.

[0019] It should be noted that, in this embodiment, when using the automatic tightening wire clamp device, Figure 1-4As shown, when clamping the high-voltage line, the electric telescopic rod 10 is opened to move the base 11 downward, and the high-voltage line is moved upward through the left top surface of the moving wedge 12. When the high-voltage line moves upward, the moving wedge 12 is acted upon by the upward moving force, and the moving wedge 12 moves toward the inside of the base 11, thereby facilitating the high-voltage line to be moved above the moving wedge 12. At the same time, according to the diameter of the clamped high-voltage line, the knob 3 is turned to rotate the screw rod 7, so that the slider 8 can drive the lifting seat 4 to adjust upward, which can prevent the lifting seat 4 and the moving wedge 12 from causing damage to the high-voltage line while clamping and tightening it, so that the clamping force is moderate. After the high-voltage line enters the moving wedge 12, it enters Inside the first clamping groove 13, at this time, since the movable wedge 12 is opened by the electric telescopic rod 10, the base 11 drives the movable wedge 12 to move downward, so that the distance between the movable wedge 12 and the lifting seat 4 is larger. Therefore, after the high-voltage line is placed, the base 11 is moved upward by the electric telescopic rod 10, so that the lifting seat 4 and the movable wedge 12 clamp the placed high-voltage line, and can clamp it firmly. When taking out the high-voltage line, the lever 17 is pushed to the left end, so that the movable wedge 12 enters the inside of the base 11 to facilitate the removal of the clamped high-voltage line. At the same time, in order to facilitate the installation of the high-voltage line, the high-voltage line can also be placed by pushing the lever 17, so that the use efficiency of the device is enhanced and convenient.
