[0022] The present invention has the following beneficial effects:

[0023] The present invention can fix and restrict the wiring harness inside different clamping assemblies through the clamping assembly, and the storage and access are very simple, thereby indirectly reducing the troublesome disassembly during maintenance, and achieving the goal of not having to remove the top cover from the car to disassemble the wiring harness in a tedious manner. The wiring harness on the top cover can be directly removed, and the dual fixation of the T-shaped plate and the push plate greatly increases the limiting and fixing effect of the wiring harness, and also increases the protection effect of the wiring harness. The special arc setting of the T-shaped plate and the push plate itself can provide all-round protection for the wiring harness, avoiding the wiring harness from being damaged, short-circuited, and unable to work due to external reasons.

[0024] The present invention rotates the components, which makes it easy for staff to select different clamping components to place the wiring harness. When the wiring harness needs to be set after each clamping component is full, the wiring harness can be placed on the side where the two fixing blocks are close to each other, and then the annular plate is rotated to confine the wiring harness within the annular plate.

[0025] The present invention achieves the effect of connecting the two top covers together through the connecting rod, and the position of the two top covers can be adjusted according to the needs of use due to the reason of the rotating shaft, which increases the practicality to a certain extent. The straight plate is used to limit the movement range of the top cover when there is no need to adjust the position of the top cover. Because the left bottom of the top cover needs to be in an inclined state when the top cover rotates, but since the inclined line is longer than the straight line, the straight plate can fix the top cover, and the threaded rod can enable the straight plate to achieve the effect of free movement.

[0026] The present invention uses the top cover to pinch the pull plate with fingers and then pull it hard to the right. The arc plate drives the T-shaped arc rod to move to the right through the clamping plate. When the clamping plate moves, it squeezes spring one, causing spring one to be compressed, and then it can automatically return to its original position through gas elastic force when the arc plate is not under force. The arc plate can protect the rotating components and the clamping components inside the top cover while protecting the wiring harness to a certain extent, further increasing the protection effect of the wiring harness. The extension distance of the arc plate can be limited by the clamping plate to avoid the collision of the pull plate with the left side of the inner wall of the opening due to excessive force during rebound, and then the pull plate breaks.

[0027] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, there is no need to remove the top cover from the car to disassemble the wiring harness. The wiring harness on the top cover can be directly disassembled, thereby reducing the troublesome disassembly during maintenance. The dual fixation of the T-shaped plate 43 and the push plate 42 greatly increases the limiting and fixing effect of the wiring harness and also increases the protection effect of the wiring harness.

[0049] One end of the two push plates 42 that is close to each other is fixedly connected to the second fixing block 44 .

[0050] An air hole 1 is provided on the side where the two air grooves are close to each other, and an air hole 2 is fixedly connected to the central axis of the air hole 1.

When the push plate 42 moves, it squeezes the spring 3, and the T-shaped plate 43 transmits the air inside the air groove to the air hole 2 through the air hole 1 when it moves. The air hole 2 will transport the air to the air groove. The push block 178 is affected by the air pressure and moves downward. When the push block 178 moves, it squeezes the spring 2. When the fixed block 2 44 drives the T-shaped plate 43 and the push plate 42 to move, the wiring harness can be placed on the inner surface of the arc block 41. Then, after the fixed block 2 44 is released, the T-shaped plate 43 and the push plate 4 2 will drive the fixing block 2 44 to return to its original position, thereby achieving the effect of clamping the wire harness. When a clamping component 179 is full of wire harnesses, other clamping components 179 can be selected to continue storing them. When each clamping component 179 is full and a wire harness needs to be set, the wire harness can be placed on the side where the two fixing blocks 1 174 are close to each other, and then the annular plate 175 is rotated to confine the wire harness in the annular plate 175. The shape of the top cover 1 can also be adjusted according to the needs of the working state. By rotating the straight The plate 4 drives the cylindrical rod 1 3 and the threaded rod 5 to rotate. As the threaded rod 5 rotates, the straight plate 4 will move to the left. When it moves to a certain extent, the top cover 1 at the top or bottom can be taken out, and then the angle can be adjusted according to the needs of the working state. When the connecting plate 21 is pulled, the cylindrical rod 2 22 can drive the cylindrical rod 1 3 and the straight plate 4 to move to the right. At this time, the bottom of the top cover 1 at the top will contact with the top of the straight plate 4, thereby keeping the top cover 1 in an inclined state, which increases the practical performance to a certain extent.
