[0029] In view of the problems existing in the prior art, the utility model provides a multifunctional screwdriver. When installing or replacing a screwdriver head 13, the rotating ring 14 is pulled clockwise to rotate. During the rotation of the rotating ring 14, the connecting rod 15 is driven to rotate. The connecting rod 15 rotates and pulls the clamping block 16 to rotate and open in the rod body 12. The screwdriver head 13 is loosened. At this time, the screwdriver head 13 can be taken out and replaced. The rotating ring 14 is pulled counterclockwise to rotate. The clamping block 16 is driven by the connecting rod 15 to rotate and fit the screwdriver head 13, so that the screwdriver head 13 is clamped and fixed. When installing or replacing the screwdriver head 13, it is simple to operate by twisting the rotating ring 14, thereby ensuring a stable clamping and fixing, which is beneficial to improving the stability of the screwdriver head 13 during use.

[0030] Working principle:

[0031] The first step is to sleeve the screwdriver head 13 inside the rod body 12, fit the screwdriver head 13 with the screw to be screwed, and screw the handle 11 to tighten or loosen the screw. The two ends of the screwdriver head 13 are of different types. The direction of the screwdriver head 13 can be adjusted and replaced, and screwdriver heads 13 of different types can be replaced to adapt to different types of screws. One handle 11 can handle multiple types of screws, which is conducive to improving the versatility and practicality of the device. When installing or replacing the screwdriver head 13, pull the rotating ring 14 clockwise to rotate, and the rotating ring 14 rotates to drive the connecting rod 15 to rotate, and the connecting rod 15 rotates to pull the clamp 1 6 is rotated and opened in the rod body 12, and the screwdriver head 13 is loosened. At this time, the screwdriver head 13 can be taken out and replaced, and the rotating ring 14 is pulled counterclockwise to rotate, and the clamping block 16 is driven by the connecting rod 15 to rotate and fit with the screwdriver head 13 to clamp and fix the screwdriver head 13. It is only necessary to screw the rotating ring 14 when installing and replacing the screwdriver head 13. The operation is simple, and a stable clamping and fixing is ensured, which is conducive to improving the stability of the screwdriver head 13 during use. When the rotating ring 14 rotates, the limiting rod 17 slides in the arc groove 18 to limit the rotating ring 14, so as to avoid excessive rotation and provide better control and protection.
