[0023] Specifically, the connecting wire 28 section located between the top of the positioning plate 27 and the top of the battery mounting frame 12 is configured as a curved structure to provide a certain stretching limit for the movement of the positioning plate 27;

[0024] An adjusting screw barrel 23 is installed on the side wall of the battery mounting frame 12 located outside the adjusting screw 24. The adjusting screw 24 extends into the adjusting screw barrel 23 and is installed with a turning handle 30. The rotation of the adjusting screw 24 is controlled by turning the turning handle 30. A barrel cap 31 is embedded in the outer end of the adjusting screw barrel 23, and the opening and closing of the adjusting screw barrel 23 is controlled by the barrel cap 31.

[0025] In one embodiment of the present invention, the clamping mounting base 13 includes an upper arc-shaped plate 15 fixed to the bottom of the battery mounting frame 12 and a lower arc-shaped plate 16 that is in contact with the upper arc-shaped plate 15.
