[0032] The tray 4 is detachably mounted on the rotating table 3. The tray 4 is injection molded from engineering plastic (such as polycarbonate PC), which has both good mechanical strength and insulation properties. The top of the tray 4 has an annular groove 400, and the annular groove 400 has slots 401. There are several slots 401, which are evenly distributed in an annular shape. The annular groove 400 has two slots 402 on both sides of the slots 401 that communicate with the slots 401.

[0033] Two clamping plates 405 are fixed on the spring sheet 404. The clamping plates 405 are engaged with the clamping slots 402. The spring sheet 404 is made of high elasticity spring steel and has a nickel-plated surface for rust prevention. The clamping plates 405 and the spring sheet 404 are integrally formed.

[0034] When a cylindrical battery is inserted into the slot 401, the spring 404 further limits the position of the cylindrical battery.

[0043] Reference Figure 1 and Figure 2The independent cavity reserved inside the workbench 1 is used to fix the controller and servo motor. The output end of the servo motor is fixedly connected to the bottom of the rotary table 3. The output shaft of the servo motor is fixed to the center hole at the bottom of the rotary table 3 by a key connection (not shown in the figure). The servo motor is mounted on the motor bracket inside the workbench 1. The bracket is isolated from the workbench 1 by shock-absorbing rubber pads to reduce the impact of motor vibration on the device.

[0044] Working principle: When the spring piece 404 needs to be maintained and replaced regularly, first rotate the fixing ring 6 counterclockwise to remove it from the rotating table 3. Then, the limiting ring 5 can be taken out from the support column 410. Then, loosen the nut 409 to remove it, so that it releases the limiting on the cover plate 406. Then, the cover plate 406 can be lifted up from the annular groove 400. Then, the operator can lift the spring piece 404 up so that the retaining plate 405 can be taken out from the retaining groove 402, thus completing the disassembly of the corresponding spring piece 404.
