The locking end is provided with a locking block 205, and the locking block 205 cooperates with the locking hole 105. The button 201 is provided with a plurality of limiting grooves 202 and a plurality of upper abutting blocks 203. The upper abutting block 203 adopts an inclined design. The abutting end is provided with a limiting plate 206 and a lower abutting block 207. The lower abutting block 207 adopts an inclined design. The button 201 can move along the length direction of the limiting plate 206 through the limiting groove 202. The inclined surface of the upper abutting block 203 is abutted and connected with the inclined part of the lower abutting block 207. A reset block 208 is provided on the lock plate 204. One end of the elastic member 209 is abutted and connected with the inner wall of the locking cavity 102, and the other end of the elastic member 209 is abutted and connected with the reset block 208.

[0028] When the trolley body is in the storage state, the elastic member 209 is in a pre-stressed state, and the elastic member 209 applies a force on the lock plate 204 in the direction close to the button 201. At this time, the locking block 205 is located in the lock hole 105, and the locking block 205 limits the rotation of the sleeve 104.
