Specifically, as shown in fig. 7, a plurality of heat dissipation grooves 17 are symmetrically formed on the outer surface of the upper end of the fixing box 1 near the front end and the rear end.

The heat dissipated by the battery box 2 can be dissipated from the heat dissipating groove 17 in time by arranging the heat dissipating groove 17, so that the battery is prevented from being broken down due to heat accumulation.

The using method comprises the following steps: when the invention is used for installing a battery box 2, a sliding block 14 is slid through a convex block 13 to compress a first spring 12, a first fixed groove 10 is opened, a rotating handle 7 is rotated to drive a first gear 5 to rotate clockwise, the first gear 5 rotates to drive two groups of first fixed rods 4 to slide into a movable chamber 6, the battery box 2 is placed into a fixed box 1, the first fixed rods 4 correspond to the positions of arc-shaped grooves 32, then the rotating handle 7 is rotated anticlockwise to drive two groups of first sliding plates 3 to slide, so that the first fixed rods 4 are driven to slide into the arc-shaped grooves 32, the rotating handle 7 rotates until clamping rods 9 enter the first fixed groove 10 through mutual clamping between the first fixed rods 4 and the arc-shaped grooves 32, the convex block 13 is released to enable the sliding block 14 to move to the initial position under the elastic force of the first spring 12, so that the first fixed groove 10 is closed, so that the rotating handle 7 is fixed, namely a lithium battery can be fixed, the device is convenient for installing the lithium battery, is beneficial to replacing and maintaining the lithium battery, when the battery box 2 vibrates, the battery box 2 moves to drive the first fixing rod 4 to move in the moving groove 23, thereby driving the second sliding plate 18 to move, causing the second spring 19 to deform, and simultaneously driving the third sliding plate 22 to move when the battery box 2 moves, causing the sliding rod 20 to move in the third sliding groove 21, causing the third spring 33 to deform, under the buffer action of the second spring 19 and the third spring 33, reducing the impact force received by the battery box 2, thereby protecting the battery box 2, preventing the battery fixing device from damaging the battery after being impacted by external force, starting the motor 24, rotating the motor 24 to drive the second gear 25 to rotate, driving the second gear 25 to drive the third gear 26 to rotate, thereby driving the heat dissipation fan 28 to rotate, produce wind-force in order to realize carrying out radiating effect to battery box 2, prevent that the lithium cell from producing a large amount of heats when using or charging, if discharge untimely, easy problem with the battery burnout takes place, improves the security of the device during operation, fixed cover 31 all through fixed connection between nut and the pivot 27 with second dead lever 29, and the model of heat dissipation fan 28 is: BS-250, the model of the motor 24 is: XD-3420-2.

The electric elements in the document are electrically connected with an external main controller and 220V mains supply through a transformer, the main controller can be a conventional known device controlled by a computer and the like, the product model provided by the invention is only used according to the structural characteristics of the product, the product can be adjusted and modified after being purchased, so that the product is more matched with and accords with the technical scheme of the invention, the product model is a technical scheme of the optimal application of the technical scheme, the product model can be replaced and modified according to the required technical parameters, and the product model is familiar to the technical personnel in the field, so that the technical scheme provided by the invention can clearly obtain the corresponding use effect.
