At the same time, the assembly method also avoids welding at multiple connection points, reducing labor intensity.

[0051] As a further scheme of the present application, the connecting assembly comprises a wedge protrusion 4 integrally arranged at the lower part of the side plate 2 and a matching opening 5 opened on the base 1, the matching opening 5 is opened along the direction of the inner side wall of the side plate 2, and the wedge protrusion 4 is adapted to the matching opening 5.

[0052] The two sides of the wedge protrusion 4 are provided with limiting blocks 401, and the two sides of the matching opening 5 are respectively provided with limiting grooves 501, and the limiting grooves 501 are adapted to the limiting blocks 401.

[0053] During the plug-in process of the wedge protrusion 4 and the matching opening 5, the wedge protrusion 4 and the matching opening 5 are tightly attached under the gravity of the side plate 2, so that the side plate 2 and the base 1 are pre-assembled, and at the same time, the limiting blocks 401 are also inserted into the limiting grooves 501.

[0055] As a further scheme of the utility model, one end of the side plate 2 is provided with a T-shaped sliding block 6, and a T-shaped sliding groove 7 is vertically formed on the base 1.

[0056] When the side plate 2 is assembled with the base 1, the T-shaped sliding block 6 is inserted into the T-shaped sliding groove 7 through the side plate 2 and is vertically slid downward, so that the wedge protrusion 4 and the matching opening 5 are inserted and connected.

[0057] In this embodiment, since the T-shaped sliding block 6 fixed on the side plate 2 and the T-shaped sliding groove 7 provided on the base 1 are matched with each other, when the side plate 2 is assembled, the T-shaped sliding block 6 is inserted into the T-shaped sliding groove 7 through the side plate 2 and is vertically slid downward, so that the wedge protrusion 4 and the matching opening 5 are inserted and connected.

[0061] As a further scheme of the utility model, the self-locking assembly comprises a connecting head 14 vertically arranged on the top cover 3 and a vertical groove 15 vertically arranged on the top of the base 1;

[0062] The connecting head 14 is located in the vertical groove 15, and the bottom of the connecting head 14 is in the shape of a circular truncated cone;

[0072] Since the two ends of the second spring 22 abut against the other end of the trapezoidal block 16 and the inner wall of the receiving groove 17 respectively, when the bottom end of the connecting head 14 passes the trapezoidal block 16, the trapezoidal block 16 can be reset.

[0073] When the top cover 3 is disassembled, since the threaded hole 18 is threadedly connected with the threaded seat 19, when a tool is inserted into the hexagonal hole 1902 and drives the threaded seat 19 to rotate, the threaded seat 19 will move outwardly from the threaded hole 18, and since the sliding plate 20 is tightly attached to the inner wall of the cavity 1901 under the action of the second spring 22, when the threaded seat 19 moves outwardly, the sliding plate 20 will also move outwardly, so that the trapezoidal block 16 moves outwardly through the connecting rod 21 along with the sliding plate 20, that is, the trapezoidal block 16 and the connecting head 14 are separated.
