The surface of the terminal block 6 is tightly pressed against the surfaces of the multiple groups of glands 4. The through-hole plate 7 is slidably connected to the surface of the slide rod 8 through the through holes opened on the surface. One end of the slide rod 8 on both sides is fixedly connected to the inner surface of the base 1. The inner surface of the base 1 is fixedly connected with a spring 10. The elastic coefficient of the spring 10 can meet the working needs according to actual needs.

[0024] The clamping device 2 includes a support rod 201 and a rotating rod 202. One end of the support rods 201 on both sides is fixedly connected to the surface of the terminal block 6. The surfaces of the support rods 201 on both sides are rotatably connected to the grooves opened on the surface of the rotating rod 202 through the protruding parts of the surface. The support rods 201 on both sides can support the rotating rods 202 on both sides to rotate a certain angle.

[0026] Working principle:
[0027] When the wires are connected to the terminal block surface:
[0028] Insert one end of the wire into the gland 4, and wind the wire around the surface of the threaded rod 5. At the same time, the operator rotates the gland 4, so that the gland 4 drives the threaded rod 5 to rotate synchronously, so that the threaded rod 5 can enter the interior of the terminal board 6, so that the gland 4 is pressed against the surface of the terminal board 6, and the wire wound on the surface of the threaded rod 5 is pressed against the surface of the copper plate 3, thereby completing the connection of the wires.
[0029] Fixed tensile process:
[0030] The stopper 904 is pressed against the surface of the base 1, and the operator pushes the groove block 901, so that the groove block 901 drives the insertion rod 902 to move synchronously, so that the insertion rod 902 drives the sliders 903 on both sides to be inserted into the grooves on the surface of the base 1. At the same time, the operator rotates the groove block 901, and under the action of the groove block 901, the sliders 903 on both sides can be driven by the insertion rod 902 to rotate synchronously, so that the sliders 903 on both sides can be engaged with the slideways inside the base 1, so that the position of the stopper 904 is fixed, and at the same time, the operator pulls the rotating rod 202, so that the rotating rod 202 can rotate a certain angle with the support rods 201 on both sides as the center, and the rotating rods 202 on both sides can drive multiple groups of frames 203 to press the wires;
[0031] At the same time, the operator rotates the bolt 204 so that one end of the bolt 204 is pressed against the surface of the terminal block 6, so that the positions of the rotating rods 202 on both sides are fixed. When the wire is subjected to tension, the tension will be transmitted to the surface of the terminal block 6, so that the terminal block 6 can drive the through-hole plates 7 on both sides to move synchronously, so that the through-hole plates 7 can compress the springs 10 on both sides, so that the terminal block 6 has a buffer space, and the length of the wire has a surplus to meet the movement of the terminal block, so that the tension can be dispersed and weakened.
