When the rear cover 23 is closed, the holding member 40 moves to the middle position and compresses the elastic member 431. When the rear cover 23 is opened, the holding member 40 is pushed outward under the elastic force of the elastic member 431 to release the limit on the top of the rechargeable battery 22, so that the rechargeable battery 22 can be pulled out upward.

[0048] Furthermore, in one embodiment, the inner wall of the rear cover 23 is provided with a protruding rib 24, and when the rear cover 23 approaches the seat body 21, the protruding rib 24 abuts against the pushing surface 402 to push the clamping member 40 to move. Furthermore, the pushing surface 402 is configured as an inclined surface, and when the rear cover 23 rotates to approach the seat body 21, the end of the protruding rib 24 moves along the inclined surface.

[0049] In this embodiment, the rear cover 23 can be movably covered on the base 21 to construct a second accommodation space A for installing the rechargeable battery 22. In one embodiment, the base 21 has a connecting plate 214 protruding toward the rear cover 23, and the connecting plate 214 includes a bottom plate disposed at the bottom of the base 21 and two side plates connected to both ends of the bottom plate, and the side plates are configured as triangular plates. The two sides of the rear cover 23 are generally trapezoidal plate structures to adapt to the connecting plate 214 of the base 21.

[0050] See also Figure 7 and Figure 8 Furthermore, the bottom of the rear cover 23 is hinged to the connecting plate 214 via the second rotating shaft 231 , and the top is buckled to the front cover 12 via the buckling assembly 30 to rotate and cover the seat body 21 .

[0051] In one embodiment, the buckling assembly 30 includes a buckling plate 31, a first rotating shaft 32 and a torsion spring 33. One end of the buckling plate 31 extends toward the front cover 12 and is provided with a clamping portion 311. The front cover 12 is provided with a clamping slot 121 adapted to the clamping portion 311. The buckling plate 31 is rotatably connected to the rear cover 23 via the first rotating shaft 32. The torsion spring 33 is disposed between the buckling plate 31 and the rear cover 23 to keep the clamping portion 311 in a clamping state with the clamping slot 121. Specifically, the front end of the buckling plate 31 is clamped with the front cover 12, and the rear end is abutted with the rear cover 23 via the torsion spring 33.

[0052] Furthermore, the torsion spring member 33 includes two spiral portions 331, a first crimping portion 332 and a second crimping portion 333 respectively connected to the two ends of the spiral portion 331, the first crimping portion 332 is connected between the two spiral portions 331 and abuts against the top surface of the back cover 23, and the second crimping portion 333 is respectively connected to the two spiral portions 331 and abuts against the bottom surface of the buckling plate 31.

[0053] Furthermore, the first rotating shaft 32 is inserted between the two spiral portions 331 , the rear cover 23 is provided with two limiting pieces 232 along the axial direction of the first rotating shaft 32 , and the first crimping portion 332 is disposed between the two limiting pieces 232 .

[0054] Furthermore, there is a gap between the rear end of the buckling plate 31 and the top of the rear cover 23. When the buckling plate 31 is subjected to a downward external force, it moves downward, driving the clamping portion 311 of the buckling plate 31 to separate from the clamping slot portion 121, thereby opening the rear cover 23.
