[0022] During the rotation of the conduction plate 103, the second conductive plate 1032 is pushed by the rubber pin 3 to slide on the insulating protective cover 2. The use length of the entire conduction plate 103 is adjusted by sliding the second conductive plate 1032. By adjusting the use length of the conduction plate 103, the conduction plate 103 is prevented from contacting with the conduction plate 103 on the adjacent pressure plate structure during rotation, so as to protect the pressure plate structure and perform secondary protection of electricity at a higher temperature.

[0023] The insulating protective cover 2 is provided with a support and extrusion assembly for supporting and extruding the first conductive plate 1031 and the second conductive plate 1032; the support and extrusion assembly ensures effective abutment connection between the first conductive plate 1031 and the second conductive plate 1032, further facilitating the stable use of the protective pressure plate structure.

[0024] Two groups of supporting and extruding components are symmetrically arranged on the upper and lower sides of the insulating protective cover 2; the extrusion effect is ensured by the two groups of supporting and extruding components symmetrically arranged up and down.

[0025] The supporting extrusion assembly includes an installation box 401 installed on the insulating protective cover 2, the installation box 401 is communicated with the interior of the insulating protective cover 2, a U-shaped frame 402 is arranged inside the installation box 401, a rotating shaft 403 is rotatably connected to the U-shaped frame 402, an extrusion roller 404 is fixed on the rotating shaft 403, and an elastic component for extruding and pushing the U-shaped frame 402 is arranged inside the installation box 401; in the process of sliding and retracting the second conductive plate 1032, the elastic force pushing action of the elastic components inside the two groups of installation boxes 401 on the U-shaped frame 402 causes the extrusion rollers 404 on the two groups of U-shaped frames 402 to respectively abut against the first conductive plate 1031 and the second conductive plate 1032, and through the abutting extrusion action, the effective abutting connection between the first conductive plate 1031 and the second conductive plate 1032 is ensured, which further facilitates the stable use of the protective pressure plate structure.

[0030] During the sliding and retracting process of the second conductive plate 1032, the elastic force components inside the two sets of installation boxes 401 push the U-shaped frame 402, so that the squeezing rollers 404 on the two sets of U-shaped frames 402 respectively abut against the first conductive plate 1031 and the second conductive plate 1032.
