The inner gear seat 405 is fixedly connected to the position corresponding to the inner toothed pulley 406 on the right side of the bottom surface of the main shell 101, and the inner toothed pulley 406 is rotatably connected to the inner gear seat 405. The first-stage reduction shaft seat 409 is fixedly connected to the position corresponding to the first-stage reduction gear 408 on the right side of the bottom surface of the main shell 101, and the first-stage reduction shaft seat 409 is rotatably connected to the first-stage reduction shaft 410.

The rear side of the first-stage rotating gear 412 is meshed with a secondary reduction gear 413, and a secondary reduction shaft seat 414 is fixedly connected to the position corresponding to the secondary reduction gear 413 on the right side of the bottom surface of the main housing 101, and a secondary reduction shaft seat 414 is rotatably connected to the secondary reduction shaft seat 414. The secondary reduction gear 413 is plugged and fixed to the upper shaft end of the secondary reduction shaft 415, and a secondary rotating bevel gear 416 is plugged and fixed to the middle position of the shaft of the secondary reduction shaft 415.

The connecting bevel gear 417 is plugged and fixed to the front shaft end of the connecting shaft 419, and the rear shaft end of the connecting shaft 419 is inserted with a rotary drive bevel gear 420, and the rotary drive bevel gear 420 is meshed with the flip bevel gear 411;

[0052] A lower slot 802 is formed at the bottom of the lithium battery body 801 in the lithium battery component 8. A positive electrode sheet 803 and a negative electrode sheet 804 are connected from left to right at the front end of the lithium battery body 801 corresponding to the positive electrode contact plate 205 and the negative electrode contact plate 206.

[0053] The front end of the bottom surface of the inner cavity of the main housing 101 is installed with a lifting drive 6, and after the lithium battery component 8 is inserted into the inner cavity of the main housing 101 from the inner insertion port 103, the top rod of the lifting drive 6 is just engaged in the lower card slot 802;

[0055] Insert the front end of the lithium battery component 8 into the inner cavity of the main housing 101 through the inner insertion port 103. After the lithium battery component 8 is inserted into the lithium battery socket 207, the positive electrode sheet 803 and the negative electrode sheet 804 connected to the front end of the lithium battery component 8 will be connected to the positive electrode connection plate 205 and the negative electrode connection plate 206.

[0056] As the lithium battery component 8 continues to be pushed inward, the positive electrode contact plate 205 and the negative electrode contact plate 206 will be brought into contact with the positive electrode plate 106 and the negative electrode plate 107;

[0057] At the moment when the positive and negative electrode connecting plates 205 and 206 are energized with the positive and negative electrode plates 106 and 107, the electromagnetic switch 5 is activated, which sends a signal to the lifting drive 6.

The connecting bevel gear 417 drives the rotation of the rotating bevel gear 420 through the connecting shaft 419. The rotating bevel gear 420 and the flip bevel gear 411 form a coordinated transmission, which can drive the rotation of the flip shaft 303, thereby driving the inward turning of the flip seat 304. With the lithium battery component 8 installed in place, the flip seat 304 drives the temperature monitoring module 305 and the flue gas monitoring module 306 to turn inward into place, and starts to monitor the use status of the lithium battery component 8 for safety.

[0059] In addition, during the use of the lithium battery component 8, the user can operate the external operating button 7 to lower the top rod of the lifting drive 6. After the lithium battery component 8 loses its position limit, the lithium battery component 8 will actively pop out under the thrust of the two sets of top springs 204, thereby realizing the disassembly of the lithium battery component 8.
