[0007] As a further solution of the utility model, one end of the longitudinal arm is fixedly connected with a mounting block.

[0008] As a further solution of the utility model, a groove is provided inside the crossbeam.

[0009] As a further solution of the utility model, a plurality of fixing plates are fixedly connected in the groove, and the fixing plates are evenly distributed.

[0010] As a further solution of the utility model, a mounting plate is fixedly connected to one side of the cross beam, and the mounting plate is fixed to the longitudinal arm.

[0011] As a further solution of the utility model, a triangular block is fixedly connected between the cross beam and the longitudinal arm.

[0012] The beneficial effects of the utility model are:

[0013] 1. By fixing the insert block and the card block in the slot and the card groove respectively, the connection between the longitudinal arm and the cross beam can be made firm, and the connecting plate further reinforces the connection between the cross beam and the longitudinal arm to prevent the connection between the longitudinal arm and the cross beam from being easily disconnected when the force is applied.

[0014] 2. The weight of the beam itself can be reduced by setting the groove, and the strength of the beam can be increased by setting the fixing plate.

[0015] 3. The triangular block in the utility model can make the connection between the cross beam and the longitudinal arm more firmly. BRIEF DESCRIPTION OF THE DRAWINGS
