At present, the automatic locking screw machines that appear on the market are generally composed of a material distribution device, an air pressure device, an air pressure delivery pipe, a chuck, and a screw driver; the working principle is: first use the material distribution device to arrange the screws and then divide them into single body, and then use the compressed air provided by the pneumatic device to blow the screw from the pneumatic delivery tube into the clamp under the screwdriver for positioning. When locking the screw, the screwdriver presses down to make the screw push away the clamp and lock it into the workpiece. However, the screw machine with this structure and form has the following defects: 1. The use cost is too high, and an air pressure device needs to be configured to realize the continuous supply of compressed air, which increases the burden on the enterprise; 2. The screw is blown into the machine by compressed air. The inaccurate positioning of the inside and rear of the clamp makes it difficult for the screw to be screwed into the screw hole, thereby easily causing screw assembly failure; 3. The structure is complex, and there is some inconvenience in the disassembly and maintenance of the parts and the use of the screw machine itself.
