The first end of the pressing strip 73 is hinged with the rotating seat 71, the second end of the pressing strip is movably embedded in the accommodating groove 721, and the top surface of the framework supports the bottom surface of the pressing strip 73. The pressing bar limiting member 74 is pivotally connected to the top end surface of the fixing base 72, and the pressing bar limiting member 74 is used for applying a pressing force to the pressing bar 73. After the framework and the plate are clamped in a limiting manner, the framework and the plate are required to be pressed tightly so as to ensure the welding effect. The pressing bar 73 is hinged to the rotating base 71, and when the skeleton needs to be pressed, the user rotates the pressing bar 73, so that the pressing bar 73 is embedded in the accommodating groove 721 of the fixing base 72. Thereafter, the user rotates the hold down bar 73 limiting assembly to limit the hold down bar 73. When the plate is not attached to the framework in place, the upper ends of the pressing strips 73 are abutted against the pressing strip limiting pieces 74 so as to apply downward pressure to the framework, and the framework is tightly attached to the plate. After the plate is tightly attached to the skeleton, the pressing strips 73 limit the top end face of the skeleton, so that the skeleton is prevented from moving in the welding process.
