DETAILED DESCRIPTION

[0017] The embodiments of the present utility model are further described below in conjunction with the accompanying drawings.

[0018] See attached Figure 1-4, a spring-type terminal block cable plugging and unplugging tool, characterized in that: it includes an upper handle 1 and a transmission member 2; the inner cavity 1a of the upper handle 1 is sleeved with a movable rod 3, an elastic component 4 is provided between a boss 3a arranged at the first end of the movable rod 3 and an inner step 1b arranged in the inner cavity 1a, an opening 1c is arranged on the upper handle 1 and passes through the inner cavity 1a, a first clamp body 5 is provided below the upper handle 1, a first end of the first clamp body 5 is hinged to a first end of a second clamp body 6, a second end of the first clamp body 5 and a second end of the second clamp body 6 are respectively provided with a first clamping portion 5a and a second clamping portion 6a opposite to each other, and the first clamp body 5 is located between the upper handle 1 and the second clamp body 6; the first end of the transmission member 2 extends into the inner cavity 1a through the opening 1c, a pin shaft 7 installed at the first end of the movable rod 3 and a slide groove 2a arranged at the first end of the transmission member 2 form a sliding fit, the second end of the movable rod 3 extends to the outside of the upper handle 1 along the length direction of the inner cavity 1a, and the transmission member 2 is hinged to the first clamp body 5. By setting the elastic component 4, when there is no external force, the movable rod 3 is in a contracted state under the elastic force of the elastic component 4, and at this time, the first clamping part 5a of the first clamp body 5 and the second clamping part 6a of the second clamp body 6 are in an open state; when it is necessary to clamp the cable, the external force pushes the second clamping part 6a of the second clamp body 6 to approach the first clamping part 5a of the first clamp body 5, and at the same time drives the transmission rod 2 to rotate, and then the slide groove 2a drives the movable rod 3 to move and makes the movable rod 3 extend outward away from the end of the transmission member 2; when using the utility model, it is only necessary to pinch the upper handle 1 and the second clamp body 6 with one hand at the same time, so that the second end of the transmission member 2 abuts against the second clamp body 6, and apply pressure to the second clamp body 6 with fingers, so as to complete the action of clamping the line and controlling the movable rod 3 to extend further. The working method of the utility model is as follows: first, the movable rod 3 is brought into contact with and aligned with the spring of the elastic terminal block, the cable to be plugged and unplugged is passed through the first clamping portion 5a of the first clamp body 5 and the second clamping portion 6a of the second clamp body 6, and the second clamp body 6 is pressed with one hand to complete the cable clamping. At the same time, the movable rod 3 is displaced to squeeze the terminal block spring, and the cable plugging and unplugging work can be completed with one hand.

[0019] Furthermore, the elastic component 4 is a spring, and the function of the elastic component 4 is: when there is no external force, under the action of the elastic force of the elastic component 4, the movable rod 3 is in a contracted state, and at the same time, a limit is applied to the second clamp body through the second end of the transmission rod 2 to make the first clamping part 5a and the second clamping part 6a in an open state.
