A handle 101 is fixed to one side of the shell 1, and an extension shell 102 is fixed to the middle end of the bottom of the shell 1. The extension shell 102 is arranged to penetrate the inside of the shell 1, and the middle end of the bottom of the extension shell 102 is penetrated and fixed with a mounting column 3, and the middle end of the top of the shell 1 is penetrated and installed with a switch column 2, and a driving motor is installed inside the shell 1. The machine is not drawn in the figure, and the driving motor is electrically connected to the switch column 2, so that when the switch column 2 is pressed, the driving motor can be turned on and off, so that it is more convenient to use the screw-driving mechanism. An extension plate 4 is fixed to the middle end of the top of the back side of the shell 1, and an auxiliary plate 401 is vertically fixed to the end of the extension plate 4 away from the shell 1, and a movable groove 404 is provided at the bottom of the extension plate 401, and a baffle 403 is slidably installed in the movable groove 404, and the baffle 403 is arranged vertically downward with the extension plate 4, and a threaded column 402 is fixed to the middle part of the auxiliary plate 401, and the threaded column 402 passes through the corresponding inner wall of the auxiliary plate 401 and is provided with threads corresponding to it, so that when the threaded column 402 is rotated in different directions, it can push or The function of pulling the baffle plate 403 to move in the moving groove 404 makes it more convenient and stable to hang the baffle plate 403 on the assembly line mechanism, and it is more convenient to take it out, so that the mechanism can be taken to any place for use, and it can also be hung on each assembly line for use. When it is hung on the assembly line for use, the position of the entire mechanism can be adjusted by pushing the outer shell 1. The mechanism can be located at different positions for use according to needs, which can effectively improve the work efficiency of personnel. An inner cover 301 is fixed inside the mounting column 3, and the bottoms of both sides of the inner cover 301 are movably installed with limit plates 8. At the same time, the height of the inner cover 301 is less than the height of the mounting column 3, but the bottom of the inner cover 301 is not flush with the bottom of the mounting column 3, and there is a gap between the limit plate 8 and the inner cover 301. The elastic member 7 is fixed for connection, and when the limit plate 8 is flipped up and down, it can be restored under the action of the elastic member 7. At the same time, the side walls of the mounting column 3 at the lower end of the limit plate 8 are provided with slots 10, and the mounting column 3 between the limit plate 8 and the slot 10 is penetrated by an inserting plate 9, and the inserting plate 9 carries the limit plate 8, and the bottom of the inserting plate 9 close to one end of the limit plate 8 is fixed with a protrusion 901, and the end of the protrusion 901 facing the slot 10 is fixed with an extension block 902, and the extension block 902 corresponds to the slot 10 at the corresponding end, so that when the inserting plate 9 is pulled, the extension block can be inserted into the slot 10, so that the movement of the inserting plate 9 is stopped and stabilized, and when the inserting plate 9 is pulled without carrying the limit plate 8, the flexible flipping of the limit plate 8 can be achieved without obstruction.And the inside of the mounting column 3 is penetrated by a mounting head 6, and a screw head 601 is fixed at the middle end of the bottom of the mounting head 6, and the screw head 601 is penetrated between the limit plates 8. At the same time, a through groove is opened in the middle of the mounting head 6, and the motor shaft 5 is penetrated in the shell. The lower end of the motor shaft 5 extends into the mounting column 3 to penetrate the extension shell 102 and the mounting column 3, and the motor shaft 5 entering the mounting column 3 corresponds to the through groove on the mounting head 6, so that the mounting head 6 is directly plugged into the motor shaft 5 for docking installation during installation. At the same time, both sides of the lower end of the motor shaft 5 are movably installed with a resistance rod 501, and the end of the resistance rod 501 away from the motor shaft 5 is arranged in an arc shape, which is convenient for the mounting head 6 to penetrate the motor shaft 5 and squeeze the resistance rod 501, so that the mounting head 6 can be installed more tightly and stably. Therefore, the rotation of the mounting head 6 can be driven during the rotation of the motor shaft 5, and it is more convenient to install and disassemble the mounting head 6, so that it is more convenient to replace the screw head 601.

[0028] Working principle: First, select the required screw head 601 according to the needs. The screw head 601 is matched with the installation head 6. Then pull out the plug plates 9 at both ends of the bottom of the installation column 3 to prompt the extension block 902 to enter the slot 10 for stability. Then use the installation head 6 to push the limit plates 8 at both ends. When the limit plates 8 are flipped and attached to the installation head 6, the installation head 6 enters the installation column 3. At the same time, push the plug plates 9 at both ends to make the extension block detach from the slot 10 to carry the limit plates 8, thereby achieving the stability of the installation head 6. Then, hang the baffle 403 on the assembly line frame of the screw as needed, and then rotate the threaded column 402 clockwise so that the threaded column 402 pushes the baffle to move in the moving groove 404 and fit tightly with the assembly line frame. When it is needed, press Lower the switch column and start the driving motor in the shell 1. The started driving motor can drive the motor shaft 5 to rotate. When the motor shaft 5 rotates, it can drive the mounting head 6 to rotate under the contact of the resistance rod 501, and the mounting head 6 drives the screw head 601 to rotate, thereby achieving the effect of tightening the screw. Secondly, when the screw head 601 needs to be replaced according to the different types of screws, the plug plates 9 at both ends of the bottom of the mounting column 3 can be pulled again to make its extension block enter the slot 10, and then the screw head 601 is pulled to squeeze the mounting head 3 out of the limiting plate from the inside of the mounting column 3, so as to achieve the effect of disassembling and replacing the screw head 601. Finally, the threaded column 402 can also be rotated counterclockwise to remove it and carry it to any different position for use. When used alone, it can be used by holding the handle 101.
