Specifically, the top inner wall of the fixing part 8 is provided with a convex block 14 extending in the direction away from the inner wall of the fixing part 8, the convex surface of the convex block 14 is an arc-shaped surface, a groove 15 matched with the convex block 14 is arranged on the pipe body of the nail outlet pipe 5, the convex block 14 rotates in the groove 15 when the fixing part 8 rotates, and a window 13 for enabling the fixing part 8 to pass through is arranged on the pipe body of the nail outlet pipe 5 in a penetrating manner. The top outer wall of the fixing member 8 is provided with an escape area 16 to prevent the corners of the fixing member 8 from restricting its rotation.
The lower part of the fixing member 8 is provided with a positioning hole 11 for positioning a screw, and a step 12 for supporting a cap portion of the screw is provided inside the positioning hole 11. The step surface of the step 12 is an inclined surface.
The working process of the hand-held screw tightening device is as follows:
the user holds the power screwdriver 20 and inserts a single screw 6 from the feed tube 4. The screw 6 passes through the feeding hole 3, the feeding channel 2 in the mounting seat 1 and the nail outlet pipe 4 in sequence, and is clamped by the fixing piece 8 in the nail outlet pipe 5. The inner cylinder 19 is then moved downwards and the batch head 21 is also moved downwards. The bits 21 pass through the feed channel 2, bottom into the outlet pipe 5, and the bits 21 rest on the screws 6. Continuing to move the inner cylinder 19 downwards, the bit 21 pushes the screw 6 downwards, expanding the two anchors 8 outwards. The bit 21 then drives the screw 6 to the top of the screw hole, and the electric screwdriver 20 performs the screw tightening operation.
