The upper end of the lifting plate 34 is connected to a guide rod, which is slidably connected to the fixing plate 33.

[0029] When the blade battery enters the thickness detection mechanism 3 , the downward pressure cylinder 32 drives the lifting plate 34 to drive the pressing plate 35 to descend, pressing on the blade battery, and detecting the thickness of the blade battery through the displacement sensor 351 .
