[0011] According to the above technical solution, one end of the connecting switch is attached to the side end of the fixed insulating frame, and one end of the power connection processing block is sleeved and connected to one end of the connecting switch.

[0012] According to the above technical solution, the power connection limiting block is rotatably installed on the side end of the power connection processing block, and the side end of the power connection limiting block is rotatably attached to the side end of the connecting switch.

[0013] According to the above technical solution, the insertion limiting block is inserted and installed inside the insertion combination hole, and the insertion limiting block is placed inside the limiting threaded cylinder.

[0014] According to the above technical solution, a correction component is provided on the side end of the fixed insulating frame;

Rotating the power-connecting limiting block engages with the connecting switch via a fusible connecting screw, achieving power connection assembly. This allows for quick assembly and connection of the switch itself, facilitating assembly and maintenance by personnel. The connection is achieved through a threaded external threaded tube and a limiting threaded sleeve. A spring return rod drives the insertion limiting block to embed into the insertion combination hole and the external connector position, enabling multi-position engagement.

[0020] 2. A correction component is provided. By using a combination nut to drive the bidirectional lead screw to move up and down along the sliding inner hollow block, the distance between the two fixed insulation frames is adjusted. This allows the spacing between components to be adjusted according to the actual dimensions during the installation of the switch components. The insertion positioning strip is embedded into the side end of the U-shaped locking block, thereby restricting the locking position of the two sets of fixed insulation frames and achieving side-end locking restriction. By using multiple sets of locking limits, the insulation frames are steadily locked in place, ensuring the stability of the overall connection. Attached Figure Description

[0032] Two of the fixed insulating frames 1 have a connecting switch 202 installed at one end via a fixing nut 201. One end of the connecting switch 202 is attached to the side end of the fixed insulating frame 1 to achieve stable alignment and connection limit. The other fixed insulating frame 1 has a power connection block 203 installed at one end via a fixing nut 201. One end of the power connection block 203 is fitted and connected to one end of the connecting switch 202 to ensure the stability of the locking alignment and locking limit.

[0033] A torsion spring 204 is installed at one end of the power connection processing block 203, and a power connection limiting block 205 is welded to one end of the torsion spring 204. The power connection limiting block 205 is rotatably installed on the side of the power connection processing block 203. The side of the power connection limiting block 205 rotates and fits against the side of the connecting switch 202 to achieve steady locking and contact cooperation, ensuring the stability of the power connection. A fusible connecting wire 206 is sleeved between the power connection limiting block 205 and the connecting switch 202.

[0034] The top of the fixed insulating frame 1 is provided with several insertion combination holes 207 at equal intervals, and several external threaded tubes 208 are welded at equal intervals on one end of the fixed insulating frame 1. The side end of the external threaded tubes 208 is connected to a limit threaded cylinder 209 through a threaded connection.

[0035] A spring reset rod 210 is snapped into the inner side of the limiting threaded cylinder 209. An insertion limiting block 211 is installed at one end of the spring reset rod 210. The insertion limiting block 211 is inserted into the inner side of the insertion combination hole 207. The insertion limiting block 211 is placed inside the limiting threaded cylinder 209 to achieve combination positioning and combination restriction.

[0036] A correction component 3 is provided on the side of the fixed insulation frame 1. The correction component 3 includes a sliding inner block 301, a bidirectional lead screw 302, a combination nut 303, a U-shaped locking block 304, and an insertion positioning strip 305.

The fusible connecting wire 206 is used to connect and combine the components, thus realizing the power connection combination process.

[0039] The insertion positioning strip 305 is embedded into the side end of the U-shaped locking block 304, thereby restricting the locking position of the two sets of fixed insulation frames 1 and realizing a stable combination connection. The fixed insulation frame 1 is sleeved at the combination position and connected to the external threaded tube 208 and the limiting threaded cylinder 209 through the thread. The spring reset rod 210 drives the insertion limiting block 211 to be inserted into the insertion combination hole 207 and the position of the external connector, realizing a multi-position locking connection, ensuring the stability of the switch connection, and enabling quick disassembly during switch installation and subsequent maintenance, reducing the occurrence of situations where disassembly is impossible due to bolt corrosion and stripping.
