By inserting the dovetail guide rail 21 of the upper shell 1 into the dovetail groove 22 of the lower shell 1, the steel ball 24 is reset and clamped in the positioning groove 25, so that the steel ball 24 fixes the dovetail guide rail 21 and the dovetail groove 22. This can avoid the low efficiency of assembling multiple shells 1. In the case of a low load, a first reinforcing rod 11 is fixed to the top and bottom of the shell 1, and a symmetrically distributed second reinforcing rod 10 is fixed to the inner wall of the shell 1. The second reinforcing rod 10 is vertically distributed with the first reinforcing rod 11, and the second reinforcing rod 10 and the first reinforcing rod 11 are cross-distributed. The second reinforcing rod 10 and the first reinforcing rod 11 can strengthen the compressive strength of the four sides of the shell 1. A return spring 26 is fixed to the inner wall of the groove 23, and one end of the return spring 26 is in contact with the outer side of the steel ball 24.
