[0027] In one embodiment, the top of the shell 1 can be opened and connected with an upper cover 20 by a hinge, a handle 21 is fixedly connected to the upper surface of the upper cover 20, a slot 17 is provided on the upper cover 20 and one side of the shell 1, a second rotating shaft 18 is fixedly connected in the slot 17 on one side of the upper cover 20, a block 19 is hinged on the outer wall of the second rotating shaft 18, the block 19 is engaged with the slot 17 in the shell 1, and the shapes of the slot 17 and the block 19 correspond.
[0028] In one embodiment, two support blocks 8 are provided, and the two support blocks 8 are located on both sides of the worm gear 14.
