[0032] The machine arm assembly assembly 3 comprises a fixed frame 31, the lower end of the fixed frame 31 is fixedly installed with the upper end edge of the bottom plate 1, the outer side bottom of the machine shell 4 is provided with three through slots 32 arranged in a surrounding manner and matched with the fixed frame 31, the inner wall bottom of the three through slots 32 is flush with the lower end of the bottom plate 1, the fixed frame 31 is inserted with a machine arm 33, the outer side top of the fixed frame 31 is movably connected with a support frame 34 in the shape of a door, the upper end of the support frame 34 is fixedly installed with an assembly mechanism for fixing the machine arm 33.

[0033] The shell mounting assembly 2 can quickly and stably mount the shell 4 outside the bottom plate 1. During installation, the worker can move the pull rod 25 away from the bottom plate 1, and after the shell 4 is correctly docked with the bottom plate 1, the pull rod 25 is loosened, and the elastic force of the spring 26 drives the two positioning rods 23 to reset and insert into the corresponding fixed holes 24, so as to ensure that the shell 4 can be tightly attached to the bottom plate 1 and kept in the correct position. Among them, the design of the sliding plate 22 and the positioning rod 23 simplifies the installation process, improves the assembly efficiency, and has strong practicality. The arm mounting assembly 3 can quickly and stably mount the arm 33 at the upper end of the bottom plate 1.
