[0025] Embodiment 1

[0026] like Figure 1-4 As shown, in the present embodiment, one end of another pull rope 440 on multiple fixing mechanisms 400 passes through one side of the plate body 100, and one end of another pull rope 440 on multiple fixing mechanisms 400 is fixedly connected with a connecting ring 441, and the inner wall of multiple connecting holes 101 is fixedly connected with two U-shaped plates 450, and both ends of the abutment plates 430 on multiple fixing mechanisms 400 are fixedly connected with sliders 433, and the two sliders 433 on the same abutment plate 430 are respectively slidably connected between the two arms of two adjacent U-shaped plates 450, and one side of the pull plate 442 is fixedly connected with a connecting hoop 443.

[0027] In this embodiment, during daily use, when it is necessary to replace the line connected to a single copper block 300, the user can pull the connecting ring 441 on the side of the copper block 300 whose line needs to be replaced, so that the connecting ring 441 drives the adjacent pull rope 440 and the push plate 430 to move without affecting the push plates 430 in other connecting holes 101, thereby facilitating use by the user, and limiting the moving direction of the adjacent push plates 430 through the U-shaped plates 450 and the sliders 433 in all the connecting holes 101, thereby improving the stability of the push plates 430 when moving. At the same time, the connecting hoop 443 allows the user to use a screwdriver or other items to lift the pull plate 442, facilitating use by the user.

[0028] like Figure 1-3As shown, in the present embodiment, a baffle plate 200 is fixedly connected to the top surface of the plate body 100, and a plurality of limit grooves 201 are provided on the top surface of the baffle plate 200, the plurality of limit grooves 201 correspond one to one with the plurality of connecting holes 101, and the plurality of limit grooves 201 are all located above the corresponding connecting holes 101, the pressure plate 420 is slidably sleeved inside the adjacent limit grooves 201, and the top surfaces of the plurality of pressure plates 420 are fixedly connected with a cantilever frame 421.

[0029] In specific implementation, when in use, the user can limit the pressure plate 420 through the limit groove 201 to prevent the pressure plate 420 from rotating when pressing the circuit on the copper block 300, and causing damage to the circuit by friction.

[0030] Embodiment 2

Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

[0035] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
