[0026] The fixing tube comprises a first fixing plate 1 and a second fixing plate 3 which are clamped together up and down. The first fixing plate 1 and the second fixing plate 3 are arc-shaped structures, and the first fixing plate 1 and the second fixing plate 3 are tubular structures as a whole in the clamping state. The bolt 5 is located on the second fixing plate 3, and the inner arc of the movable plate 4 faces the inner arc of the first fixing plate 1. The inner arcs of the movable plate 4 and the first fixing plate 1 are both concave surfaces, and the outer arc is a surface convex outwardly. The inner arc of the movable plate 4 is the bottom, and the inner arc of the first fixing plate 1 is the top. Through the first fixing plate 1 and the second fixing plate 3, there is no need to rotate the bolt 5, and the bolt 5 is used to adjust the position of the movable plate 4, so that the movable plate 4 can clamp lines of different sizes. The movable plate 4 is driven to move by the second fixing plate 3, so that the movable plate 4 and the first fixing plate 1 clamp the lines, which can reduce the number of times the bolt 5 is screwed, protect the threaded holes on the second fixing plate 3, and extend the service life of the bolt 5 and the threaded holes on the second fixing plate 3.

[0027] A fixing block 2 is fixed to the bottom of the right side of the second fixing plate 3. The fixing block 2 is an arc-shaped block. The curvature of the fixing block 2 is consistent with the curvature of the second fixing plate 3. One side of the first fixing plate 1 and the second fixing plate 3 are hinged. The left sides of the first fixing plate 1 and the second fixing plate 3 are hinged by hinges, and the first fixing plate 1 and the second fixing plate 3 swing left and right. The outer side wall of the second fixing plate 3 is flush with the outer side wall of the fixing block 2, and the length of the fixing block 2 is smaller than the length of the second fixing plate 3. The outer side wall of the first fixing plate 1 away from the hinged side is provided with a first groove for inserting the fixing block 2. The outer side wall of the right side of the first fixing plate 1 is provided with a first groove.

The mounting groove is a circular structure. A bearing is provided between the fixing column 6 and the mounting groove. The inner ring of the bearing is fixedly sleeved on the fixing column 6. The outer ring of the bearing is fixed to the mounting groove. The fixing column 6 is connected to the movable plate 4 through the bearing, that is, the bolt 5 is connected to the movable plate 4. When the bolt 5 rotates, the movable plate 4 will not be driven to rotate through the bearing. Therefore, by twisting the bolt 5, the movable plate 4 can be moved up and down. This paragraph of text as a whole constitutes a connection assembly for connecting the bolt 5 to the movable plate 4 and allowing the bolt 5 to rotate independently.

[0030] Of course, in actual use, the connecting component can also be a circular plate fixed at the end of the screw rod of the bolt 5 away from the nut, the diameter of the screw rod of the bolt 5 is smaller than the diameter of the circular plate, and a fixing ring is independently sleeved on the outside of the circular plate. The bottom of the fixing ring is fixed to the top of the movable plate 4, and a limiting plate is fixed on the top of the fixing ring to prevent the circular plate from detaching. The limiting plate is in the shape of a circular ring, and the inner ring diameter of the limiting plate is smaller than the diameter of the circular plate to prevent the circular plate from passing through the inner ring of the limiting plate.

[0031] The outer arc surface of the movable plate 4 is fixed with a guide rod 14 parallel to the screw of the bolt 5, and the second fixed plate 3 is provided with a third through hole for the guide rod 14 to pass through. The top of the movable plate 4 is an outer arc surface, and the guide rod 14 is vertically fixed on the top of the movable plate 4. The rotation of the movable plate 4 can be restricted by the guide rod 14, so that when the bolt 5 rotates, the movable plate 4 moves up and down.

[0032] The guide rods 14 are provided with two, and the two guide rods 14 are symmetrically distributed with the bolt 5 as the center, and the two guide rods 14 are both located in the length direction of the second fixing plate 3, the first fixing plate 1 and the second fixing plate 3 form a tubular structure connected front to back, and the two guide rods 14 are symmetrically distributed front to back with the bolt 5 as the center, and the movable end of the guide rod 14 passes through the third through hole and is fixed with a second limit block 15 to prevent the guide rod 14 from escaping from the third through hole, and the second limit block 15 is a circular plate, and the diameter of the third through hole is smaller than the diameter of the second limit block 15, so that the top end of the guide rod 14 can be prevented from escaping from the third through hole on the second fixing plate 3.

[0033] The fixed tube and the movable plate 4 are both made of insulating materials, and are made of plastic. Of course, the fixed tube and the movable plate 4 can also be made of wood. The inner arc surface of the first fixed plate 1 is provided with a first rubber layer 9, the top of the first fixed plate 1 is provided with a first rubber layer 9, the inner arc surface of the movable plate 4 is provided with a second rubber layer 7, and the bottom of the movable plate 4 is provided with a second rubber layer 7. The second rubber layer 7 and the first rubber layer 9 are both made of rubber. The second rubber layer 7 and the first rubber layer 9 can improve the insulation effect, and the second rubber layer 7 and the first rubber layer 9 can prevent the movable plate 4 and the first fixed plate 1 from directly contacting the circuit, thereby protecting the circuit.

[0034] A stopper 8 is fixed at one end of the first fixing plate 1, and the stopper 8 is fixed at the rear end of the top of the first fixing plate 1. The rear end of the first fixing plate 1 is blocked by the stopper 8, so that when the line is placed in the first fixing plate 1, the stopper 8 can locate the position of the end of the line, thereby preventing the end of the line from exceeding the rear side of the first fixing plate 1 and preventing the line from being exposed to the outside of the first fixing plate 1 and the second fixing plate 3, thereby achieving a better protection effect.

[0035] Working principle:

[0036] When the reactive power compensation cabinet is repaired, the distance between the movable plate 4 and the first fixed plate 1 is adjusted according to the size of the line, so that the movable plate 4 and the first fixed plate 1 can clamp wires of different sizes. After the parts and lines in the reactive power compensation cabinet are disassembled, the first fixed plate 1 and the second fixed plate 3 are opened, and the end of the line is placed between the first fixed plate 1 and the second fixed plate 3, and then the first fixed plate 1 and the second fixed plate 3 are connected, so that the movable plate 4 and the first fixed plate 1 clamp the line to prevent the end of the line from being exposed. After the parts are replaced or repaired, the first fixed plate 1 and the second fixed plate 3 are opened, the line is taken out, and reconnected to the replaced electrical appliance, and the first fixed plate 1 and the second fixed plate 3 can be reused, which can reduce the waste of resources, and the operation is simple and convenient.
