The sealing cap 4 is circular in shape and conforms to the port of the housing 5 with a clearance fit. After the upper port of the shell 5 is covered by the sealing cover 4, an annular gap exists between the edges of the sealing cover 4 and the shell 5, so that heat exchange is conveniently carried out between the inner cavity of the shell 5 and the external environment, and the heat dissipation efficiency is improved.
The lifting seat 2 comprises a lifting plate 21, a lifting rod 22, a guide cylinder 23, a bottom plate 24, an adjusting rod 25, a supporting seat 26 and a bearing seat 27; the guide cylinder 23 is screwed on the upper side of the bottom plate 24 by screw threads; the base plate 24 is rectangular; the supporting base 26 is screwed on the upper side of the bottom plate 24 by bolts; the lifting rod 22 is slidably arranged in the guide cylinder 23 in a penetrating way and extends out of the upper end of the guide cylinder 23; the adjusting rod 25 is hinged at the upper end of the supporting seat 26, and one end of the adjusting rod is screwed at the lower part of the lifting rod 22 by threads; the bearing seat 27 is fixed on the upper end of the lifting rod 22 by bolts; the lifting plate 21 is fixed to the upper side of the bearing base 27 by bolts.
The lifting rod 22 comprises a rod body 221 and a first nut 222; the rod 221 is a circular rod, and the first nut 222 is screwed on the rod 221; the guide cylinder 23 includes a lifting adjustment groove 231 and a cylinder 232; a first spring 223 is pressed at the bottom of the cylinder 232; the first spring 223 is sleeved at the lower end of the rod body 221, one side of the first nut 222 close to the bottom surface of the inner cavity of the cylinder body 232 forms an annular surface, and the first spring 223 is tightly pressed on the annular surface;

The battery can generate heat when in use, and the heat is difficult to be radiated due to the tight sealing of the existing battery fixing frame. In the present invention, the battery is placed on the plate body 211, and the hot air flows along the ventilation groove 212 and flows out from the elevating plate 21, thereby achieving the heat emission. The hot air flows from the ventilation slot 212 into the lower side of the lifting plate 21, then enters the inner cavity of the base 3, and then flows out of the base 3 through the gap between the two adjacent fan blades 61, thereby dissipating heat. The size of the gap between the two blades 61 is adjusted by rotating the blades 61 to adjust the inclination angle thereof. When the heat dissipation needs to be accelerated, the rotating fan blades 61 adjust the gap between the two adjacent fan blades 61 to a larger extent, so that the air circulation is accelerated, and the heat dissipation needs under various conditions are met.
The adjusting bracket 1 comprises a cover 11, a connecting ball 12, a handle 13, a positioning rod 14, a connecting ring 15, a first screw 16, a positioning groove 17, a positioning hole 18 and a mounting plate 19; the mounting plate 19 is a cuboid, and a rotary groove and an adjusting hole are arranged in the mounting plate in a penetrating manner, and the adjusting hole is communicated with the rotary groove.

The positioning groove 17 is recessed in the positioning rod 14 in the radial direction of the positioning rod 14, and the positioning groove 17 extends in the axial direction of the positioning rod 14. The first screw 16 is screwed into the mounting plate 19 with a screw thread, and one end of the first screw 16 abuts against the positioning slot 17. The rotation groove is hemispherical and the connection ball 12 is spherical.
When the locking device is used, the positioning rod 14 slides along the positioning hole 18, after the positioning rod 14 moves to the target position, the first screw rod 16 is rotated, the end part of the first screw rod 16 is tightly pressed into the positioning groove 17, and the positioning rod 14 is locked. After the positioning rod 14 is locked, the connection ring 15 fixes the positions of the connection ball 12 and the handle 13 at the same time, and the adjustment lever 25 is fixed after the position of the connection ball 12 is fixed.
