[0024] Among them, the mounting seat 2 and the top surface of the cabinet 1 are vertically arranged, and there are two mounting seats 2 in total. The two mounting seats 2 are fixedly connected to the left and right sides of the top surface of the cabinet 1 in a linear array. The cabinet 1 and the mounting seat 2 together constitute a supporting structure. The outer side of the mounting seat 2 is fixedly connected with an electric push rod 201. There are two electric push rods 201 in total, and the two electric push rods 201 are respectively fixedly connected to the outer side surfaces of the two mounting seats 2.
