[0023] Specifically, the wire feeder 2 is connected to the handheld part 3, and a screw is arranged inside the wire feeder 2, and the screw is delivered to the handheld part 3 by an air pump. This is the prior art, and its specific structure and working principle are not repeated here. The wire feeder 2 is fixedly installed on the frame 1, and a receiving groove is opened on the outer wall of one side of the frame 1, and the clamping unit 5 is arranged on one side of the receiving groove. Specifically, the mounting frame 4 includes a supporting frame 41 and a supporting rod 42, and the supporting frame 41 and the supporting rod 42 are both fixedly installed on the outer wall of one side of the frame 1, and a lifting frame 6 is movably arranged on the support rod 42, the handheld part 3 is fixedly connected to the lifting frame 6, and a spring balancer 7 is arranged on the supporting frame 41, and the spring balancer 7 is connected to the lifting frame 6, and the lifting frame 6 is suspended on the outer wall of the support rod 42 by the spring balancer 7, so that the lifting frame 6 can rotate freely and can automatically retract when pressed down to a certain amplitude, so as to realize the connection between the screw and the component to be installed.

[0024] The hand-held part 3 is movably connected to the support rod 42 through the lifting frame 6, and can be freely rotated on the outer wall of the support rod 42. The spring balancer 7 arranged on the support frame 41 is connected to the lifting frame 6, so that the lifting frame 6 can be suspended on the frame 1, so that the user can freely rotate the lifting frame 6 during use to align it with the position where it needs to be installed. At the same time, the hand-held part 3 can be lowered through the lifting frame 6 to complete the tightening of the screws. There is no need to manually hold the hand-held part 3, which can save the operator's physical strength, facilitate the operator to install the screws, and improve production efficiency.
