[0031] Example 2

[0032] The present embodiment is different from the embodiment 1 in that: specifically, the clamping and disassembling assembly 6 includes a disassembling seat 61, a square plug block 62, a clamping rod 63, a clamping slide block 64 and a clamping spring 65, wherein the disassembling seat 61 is arranged above the isolating switch body 4, a square plug block 62 is inserted on one side of the disassembling seat 61, a clamping rod 63 is arranged on one side of the square plug block 62, a clamping slide block 64 is arranged on one side of the clamping rod 63, and a clamping spring 65 is arranged on one side of the clamping slide block 64.

[0035] By adopting the above technical solution, the guide slide makes it easy for the square plug block 62 to abut against the clamping rod 63 when it is installed, and can drive the clamping rod 63 to move to one side. The clamping hole facilitates the insertion of the clamping rod 63 to fix the square plug block 62.

[0036] When this embodiment is in use: pull the clamping rod 63, the clamping rod 63 drives the clamping slider 64 to move and compress the clamping spring 65, so that the clamping rod 63 is disengaged from the clamping hole, and then the square plug block 62 and the disassembly seat 61 can be separated, thereby separating the protective cover 5 and the isolating switch body 4, so that the internal inspection and maintenance can be carried out. When the device is in use, the protective cover 5 can be quickly opened and closed, and the internal inspection and maintenance can be carried out, thereby improving the convenience of use.

[0037] The structure and use principle of the isolating switch body 4, the protective cover 5 and the handle 7 in the utility model have been disclosed in an electrical isolating switch disclosed in Chinese patent application No. 201820512900.8. Its working principle is to electrically connect the power cord and the equipment wire to the static contact respectively, and then screw the handle 7 to drive the block to rotate. At this time, the positioning torsion spring is tightened, and the rotation of the block drives the moving contact on the ceramic square tube to rotate. The moving contact rotates and is buckled into the static contact through the convex point, and the equipment is powered on; when the equipment needs to be powered off, the handle 7 is screwed in the reverse direction. At this time, the positioning torsion spring stretches and drives the handle 7 to reset quickly. The reset of the handle 7 drives the moving contact to slide out quickly from the static contact, so that a larger insulation gap is generated between the static contact and the moving contact.

[0038] Working principle and use process of the utility model: When the utility model is used, the isolating switch body 4 is clamped and fixed by the clamping component 3, and then it can be used. When in use, the power can be turned on and off by cooperating with the handle 7 and the isolating switch body 4, which is convenient to use. When the device needs to be removed, the isolating switch body 4 can be removed by the clamping component 3, which is simple and quick, and then the protective cover 5 and the isolating switch body 4 are separated by the clamping disassembly component 6, so that maintenance can be carried out. When the clamping component 3 is in use, the handle 33 is rotated, and the rotation of the handle 33 drives the bidirectional trapezoidal screw rod 32 to rotate, and the rotation of the bidirectional trapezoidal screw rod 32 drives the square slider 34 to move, and the square slider 34 moves to drive the connecting block 35 to move, and the connecting block 35 moves to drive the fastening component 36 to move and the clamping plate 3 7 cooperates to clamp and fix the isolating switch body 4. When the fastening component 36 is in use, the clamping plate 37 moves and compresses the fastening spring 362 in the fastening seat 361, so that the device is clamped and fixed effectively, so that the device can be conveniently disassembled and assembled when in use, and the structure is easy to use, which improves the convenience of use. When the clamping and disassembling component 6 is in use, the clamping rod 63 is pulled, and the clamping rod 63 drives the clamping slider 64 to move and compress the clamping spring 65, so that the clamping rod 63 is disengaged from the clamping hole, and then the square plug block 62 and the disassembly seat 61 can be separated, thereby separating the protective cover 5 from the isolating switch body 4, so that the internal inspection and maintenance can be carried out, so that the protective cover 5 can be quickly opened and closed when the device is in use, so that the internal inspection and maintenance can be carried out, which improves the convenience of use.
