After the winding column 202 rotates, the wires 9 in the protection box 2 will be gradually wound around the outer wall of the winding column 202. After the winding is completed, the first pull block 206 is released, and the first pull block 206 will be A reset spring 207 drives the reset, so that the square column 204 limits the rotating column 203 again. If it is found that the reset cannot be performed, the knob 205 can be appropriately turned to reset the square column 204. After the reset is completed, the winding column 202 can no longer rotate, and the wire 9 wound on the outer wall of the winding column 202 will not be easily loosened, so that the winding of the wire 9 can be completed, and the excess part of the wire 9 can be stored in the interior of the protective box 2, and the wire 9 can be properly wound up by the winding column 202, so that the space occupied by the wire 9 is reduced, and friction between the wire harnesses is not likely to occur during the driving of the car, thereby increasing the service life of the wire harness and also increasing safety.

[0035] Further:

[0036] A knob 205 is integrally formed at the top of the rotating column 203, and anti-slip stripes are arranged on the outer wall of the knob 205. A storage groove adapted to the wire harness is arranged on the outer wall of the winding column 202.

[0044] A mounting bracket 208 is fixedly installed at the front end of the protection box 2, and a groove matching the square column 204 is opened on the top surface of the mounting bracket 208. A first pull block 206 is fixedly installed on the top of the square column 204, and a first return spring 207 is fixedly installed between the first pull block 206 and the top surface of the mounting bracket 208. The square column 204 can be easily pulled outward by the first pull block 206, so that the square column 204 is separated from the rear half of the through groove of the rotating column 203, so that the rotating column 203 is no longer limited by the square column 204, and the rotating column 203 can be rotated and stored. By setting the first return spring 207, the square column 204 can be reset by the elastic force of the first return spring 207 after being pulled by the first pull block 206, making the use of the device easier.

[0045] Working principle: when in use, first put the wire 9 into the protection box 2 through the front side of the protection box 2, then wrap the wire 9 near the front end of the protection box 2 around the front end of the loading and unloading reel 202, then pull the first pull block 206 outward to make the first pull block 206 drive the square column 204 to move, so that the square column 204 no longer limits the rotating column 203, and then rotate the rotating column 203 through the knob 205. After the rotating column 203 rotates, the reel 202 fixedly installed on the outer wall of the rotating column 203 will also start to rotate. The wires 9 in the protective box 2 will be gradually wound around the outer wall of the winding column 202. After the winding is completed, the first pull block 206 is released and the first pull block 206 is driven to reset by the first reset spring 207, so that the square column 204 can limit the rotating column 203 again. If it is found that it cannot be reset, the knob 205 can be appropriately rotated to reset the square column 204. After the reset is completed, the winding column 202 can no longer rotate, and the wires 9 wound on the outer wall of the winding column 202 will not be easily loosened, so that the winding of the wires 9 can be completed.

[0046] By setting up a winding component, the device can store the excess part of the wire 9 into the interior of the protective box 2, and the wire 9 is properly wound up through the winding column 202, so that the space occupied by the wire 9 is reduced, and friction between the wires is not likely to occur during the driving of the car, thereby increasing the service life of the wire harness and also increasing safety.

[0047] By setting up the card-connecting assembly, the device can operate various parts in the protection box 2 by opening the protective cover 4 during use, thereby reducing the difficulty of maintenance. At the same time, after completing the winding and maintenance, the card block 702 can be separated from the range of the docking groove 201 by pulling the second pull block 701, and then the protective cover 4 is rotated to the top surface of the protection box 2, and then the second pull block 701 is released. The elastic force of the second return spring 8 will drive the card block 702 to be inserted into the card slot 6, so that the protective cover 4 will not be easily opened, and the wires 9 in the protection box 2 can be better protected. At the same time, the existence of the second return spring 8 prevents the card-connecting assembly from being easily opened without human power.
