Limiting grooves 27 are evenly and equidistantly provided, and the three inserting blocks 21 are respectively matched with the three limiting grooves 27. When the screwdriver bit 26 needs to be installed, the screwdriver bit 26 can be inserted into the circular groove 13, and then the threaded ring 14 can be rotated on the connecting column 12. Since the two are in a threaded connection state, the screwdriver bit 14 will move toward the handle 11 under the rotation of the threaded ring 14. At this time, the threaded ring 14 will contact the three wedge blocks 22. At this time, the three wedge blocks 22 will be forced to drive the three inserting blocks 21 to move toward the inside of the connecting column 12. When the three inserting blocks 21 slide into the three limiting grooves 27, the screwdriver bit 26 will be limited, and then After the installation is completed, the installation and removal of the screwdriver bit 26 of the device is more convenient and labor-saving when in use; when installing, the plug block 21 will also drive the side bar 23 to move toward the inside of the connecting column 12, and the movement of the side bar 23 will also drive the cross block 24 to slide inside the cross groove 17, and the side bar 23 will also drive the spring 25 to be compressed when moving, and when the screwdriver bit 26 needs to be removed, the spring 25 will restore the elastic force, and then drive the plug block 21 to quickly pop out of the limit groove 27, thereby quickly completing the separation between the screwdriver bit 26 and the connecting column 12, making the device more convenient when in use.

[0026] In view of the problems existing in the prior art, the utility model provides a screwdriver with a replaceable screwdriver bit. Through the design of the handle 11, the connecting column 12, the threaded ring 14, the plug block 21, the wedge block 22, the screwdriver bit 26 and the limiting groove 27, the threaded ring 14 can be rotated on the connecting column 12. Since the two are in a threaded connection state, the threaded ring 14 will move toward the handle 11 under the rotation. At this time, the threaded ring 14 will contact the three wedge blocks 22. At this time, the three wedge blocks 22 will be subjected to force to drive the three plug blocks 21 to move toward the inside of the connecting column 12. When the three plug blocks 21 slide into the three limiting grooves 27, the screwdriver bit 26 will be limited, and the installation is completed, so that the installation and disassembly of the screwdriver bit 26 is more convenient and labor-saving when the device is in use.

[0027] Working principle:

[0028] In the first step, when the bit 26 needs to be installed, the bit 26 can be inserted into the circular groove 13, and then the threaded ring 14 can be rotated on the connecting column 12. Since the two are in a threaded connection state, the threaded ring 14 will move toward the handle 11 under the rotation of the threaded ring 14. At this time, the threaded ring 14 will contact the three wedge blocks 22. At this time, the three wedge blocks 22 will be driven by the force to drive the three plug blocks 21 to move inside the connecting column 12. When the three plug blocks 21 slide into the three limiting grooves 27, the bit 26 will be limited at this time, and then the installation is completed, so that the installation and disassembly of the bit 26 is more convenient and labor-saving when the device is used;

[0029] In the second step, during installation, the insert block 21 will also drive the side strip 23 to move toward the inside of the connecting column 12, and the movement of the side strip 23 will also drive the cross block 24 to slide inside the cross groove 17. The side strip 23 will also drive the spring 25 to be compressed when moving. When the bit 26 needs to be disassembled, the spring 25 will restore its elastic force, and then drive the insert block 21 to quickly pop out of the limit groove 27, thereby quickly completing the separation between the bit 26 and the connecting column 12, making the device more convenient to use.

[0030] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods.
