The outer surface of the wire 305 is in contact with the outer surfaces of the winding cylinder 315 and the plurality of identical rollers 317.

[0026] A dismounting plate 302 is arranged on the outside of the rectangular frame 301, one side of the dismounting plate 302 is in contact with one side of the rectangular frame 301, by arranging the dismounting plate 302, the dismounting plate 302 can be dismounted from one side of the rectangular frame 301, facilitating inspection work; One side of the disassembly plate 302 is fixedly connected with two groups of clamping shafts 309, each group of clamping shafts 309 has two clamping shafts, the left side of the rectangular frame 301 is provided with two groups of clamping grooves 310, each group of clamping grooves 310 has two clamping grooves, the outer surface of each clamping shaft 309 is clamped in the clamping groove 310, the clamping shaft 309 is clamped in the clamping groove 310, and the disassembly plate 302 is indirectly fixed on one side of the rectangular frame 301 through the clamping shaft 309 and the clamping groove 310; One end of the wire 305 is fixedly connected with the first connecting head 306, the outer surface of the first connecting head 306 is clamped in the inside of the heat dissipation shell body 1, the other end of the wire 305 is fixedly connected with the second connecting head 304, and the first connecting head 306 and the second connecting head 304 are arranged, so that the device and the battery are connected.

One end of the winding cylinder 315 is provided with a cross-shaped sliding groove 314, and the cross-shaped sliding groove 314 is slidably connected with a cross-shaped sliding block 311. The cross-shaped sliding groove 314 and the cross-shaped sliding block 311 are arranged, and the cross-shaped sliding block 311 can slide in the cross-shaped sliding groove 314. One side of the cross-shaped sliding block 311 is fixedly connected with a rotating plate 303, one side of the rotating plate 303 is fixedly connected with a plurality of same short shafts 312, one side of the disassembly plate 302 is provided with a plurality of same circular grooves 313, the outer surface of each short shaft 312 is clamped in the circular groove 313, and the rotating plate 303 can be drawn out by a distance under the joint action of the cross-shaped sliding block 311 and the cross-shaped sliding groove 314, and the cross-shaped sliding block 311 can still play a transmission role.

[0027] The specific implementation of the embodiment is: when the device needs to be used, the rotary plate 303 is pulled outward, the short shaft 312 fixed on one side of the rotary plate 303 is disengaged from the clamping relationship with the circular groove 313, then a counterclockwise rotating force is applied to the rotary plate 303, the wire 305 inside the rectangular frame 301 is moved to the outside of the rectangular frame 301, the wire 305 inside the rectangular frame 301 is gradually tightened, the force spring 307 is compressed, then the second connecting head 304 is installed to a suitable position and the short shaft 312 is clamped into the circular groove 313, when the wire 305 is pulled, the pulling force of the wire 305 is applied to the winding cylinder 315 by the friction between the wire 305 and the winding cylinder 315, the winding cylinder 315 cannot rotate under the joint action of the rotary plate 303, the cross slider 311, the short shaft 312 and the circular groove 313, so the wire harness cannot apply the pulling force to the first connecting head 306, conversely when the wire 305 needs to be retracted, the rotary plate 303 is pulled outward, the short shaft 312 fixed on one side of the rotary plate 303 is disengaged from the clamping relationship with the circular groove 313, then a clockwise rotating force is applied to the rotary plate 303, the cross slider 311 is rotated, the winding cylinder 315 is rotated, the winding cylinder 315 is retracted when rotating, the wire harness outside the rectangular frame 301 is accumulated inside the rectangular frame 301, the wire harness inside the rectangular frame 301 is in a non-tight state, the force spring 307 releases the elasticity, the lifting plate 316 and the roller 317 are pushed to unfold the wire harness inside the rectangular frame 301, the work of winding and arranging the wire harness is completed.

[0028] In the embodiment 3, the support frame 203 is arranged inside the heat dissipation shell body 1, and can provide support force for the battery pack. When the outer layer of the battery pack is broken, the electrolyte inside the battery pack can flow to the guide plate 204 through the gap on the surface of the support frame 203. The electrolyte can be gathered in the middle part of the guide plate 204 by the inclined surface design on the surface of the guide plate 204. The electrolyte can be concentrated on the surface of the rotating plate 208. With the accumulation of the electrolyte, the weight of the electrolyte can push the rectangular plate 205 to rotate. The rotation of the rectangular plate 205 can drive the long shaft 206 to rotate, and further drive the rotating plate 208 to rotate. The surface of the rotating plate 208 is covered with green and red colors, and the green coverage area is much smaller than the red coverage area. In the normal state, the green area on the rotating plate 208 corresponds to the gap on the surface of the circular shell 209. When the rotating plate 208 rotates due to the leakage of the electrolyte, the red area on the rotating plate 208 can be moved to the gap on the surface of the circular shell 209, so as to achieve the purpose of warning the outside. Then, the electrolyte can be accumulated in the collection frame 201. The adsorbing cotton is arranged in the collection frame 201, and can adsorb the leaked electrolyte. The problem that the leaked electrolyte is accumulated in the heat dissipation shell body 1 to corrode the equipment during use of the device can be avoided. At the same time, the staff need not open the heat dissipation shell body 1 regularly to check the leakage of the electrolyte. It is only needed to regularly observe the color of the position corresponding to the gap of the circular shell 209. When the device needs to be used, the rotating plate 303 is pulled outward, so that the short shaft 312 fixed on one side of the rotating plate 303 is separated from the clamping relationship with the circular groove 313. Then, the rotating plate 303 is subjected to counterclockwise rotation, so as to drive the wire 305 in the rectangular frame 301 to move outward. Therefore, the wire 305 in the rectangular frame 301 is gradually tightened, so as to push the stressed spring 307 to be compressed. Then, the second connecting head 304 is installed in a suitable position, and the short shaft 312 is clamped into the circular groove 313. When the wire 305 is subjected to pulling force, the pulling force of the wire 305 can be applied to the winding cylinder 315 by the friction between the wire 305 and the winding cylinder 315. At this time, the winding cylinder 315 cannot rotate under the joint action of the rotating plate 303, the cross slide 311, the short shaft 312 and the circular groove 313. Therefore, the wire harness can be prevented from applying pulling force to the first connecting head 306. Conversely, when the wire 305 needs to be retracted, the rotating plate 303 is pulled outward, so that the short shaft 312 fixed on one side of the rotating plate 303 is separated from the clamping relationship with the circular groove 313. Then, the rotating plate 303 is subjected to clockwise rotation, so as to drive the cross slide 311 to rotate, and further drive the winding cylinder 315 to rotate. When the winding cylinder 315 rotates, the second connecting head 304 can be retracted in the direction of the rectangular frame 301. At the same time, the wire harness outside the rectangular frame 301 is accumulated in the rectangular frame 301. At this time, the wire harness in the rectangular frame 301 is in a non-tight state.Therefore, the stressed spring 307 will release the elasticity, push the lifting plate 316 and the roller 317 to spread the wire harness inside the rectangular frame 301, complete the work of winding and arranging the wire.
