Since the upper inserting rod 59 and the lower inserting The rods 60 are respectively inserted in the upper socket 35 and the lower socket 36, thereby locking the door 31. When the door 31 needs to be opened, only the handle 64 needs to be rotated in the opposite direction. In addition, a door lock that locks the handle 64 is also required so that the handle 64 cannot be rotated after the door is locked.

Setting two upper fixing guide sleeves 57 and two lower fixing guide sleeves 58 can ensure that the upper insertion rod 59 and the lower insertion rod 60 move in the vertical direction and ensure good meshing with the gear 63 .

This embodiment does not impose any formal restrictions on the shape, material, structure, etc. of the utility model. Any simple modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the utility model belong to the technology of the utility model. protection scope of the program.
