Abstract

The invention relates to a screw-driving device, in particular to a hand-held screw-driving device. Technical problem: Provide a hand-held screw-driving device that can save manpower, is safe, and has high efficiency. The technical solution is: a hand-held screw-tightening device, including a hand-held device, an external hose, an intermediate round box, etc.; the right side of the hand-held device is connected with an external hose, and the external hose is provided with a power cord and an external air pipe . In the present invention, by pushing the screw into the storage box, under the action of the spring, the arc-shaped rods on the left and right sides can clamp the screw, which can make screwing more convenient and fast; the connecting ring frame can be driven to rotate by the servo motor , so as to drive the placement box to rotate, so that the placement box can be rotated one by one to the right below the impact screw-in device; through the impact screw-in device, the screws in the placement box can be screwed to the desired position, thereby saving manpower and improving screw screwing efficiency .

Description

technical field [0001] The invention relates to a screw-driving device, in particular to a hand-held screw-driving device. Background technique [0002] The screw is a tool for tightening the parts of the object step by step by using the physical and mathematical principles of the oblique circular rotation and friction of the object. [0003] In the process of building construction, people often need to use screws to fix materials. At present, people often use screwdrivers to screw screws. Sometimes slipping occurs during the screw screwing process, which causes people's hands to be injured, and some materials It is relatively hard, and it is difficult to screw in the screws, which requires more manpower. In this way, people will use an electric screwdriver to complete it. When using an electric screwdriver to screw the screws, they need to place the screws one by one by hand. The efficiency of screwing. [0004] Therefore, it is necessary to develop a hand-held screw-twis...
