As a preference, a box is provided at the rear end of the handle, the slider crank mechanism is arranged in the box, and a rotating wheel that drives the cam to rotate is provided on the outside of the box, the structure is simple, and the slider crank mechanism can be well protected. Reciprocating motion, not easy to damage, easy to use, the rotating wheel can conveniently make the crank slider mechanism move.

Preferably, the rotating wheel is provided with a handle, which is simple in structure and easy to use, and the reciprocating motion of the crank slider mechanism is realized by turning the handle to drive the rotating wheel, which can make it more convenient and labor-saving for the user to screw the screw.

Preferably, the front end of the knife rod is provided with a screwdriver installation head, and the screwdriver is arranged in the screwdriver installation head, which is convenient for disassembly and replacement of the screwdriver, and has a wide range of applications. When different screws are needed, it can be completed by replacing the screwdriver.

Preferably, the front end of the handle is provided with a handle support frame, which is novel in shape and very similar in appearance to the original cannon. When the screwdriver is not in use, it can be displayed at home as a handicraft, and the handle support frame can be used to elevate the barrel of the cannon. The mouth function can better attract children's attention, and can be used as a toy for younger children; at the same time, because the structure is relatively simple and easy to disassemble, it can also be used as a toy for older children to understand mechanical structures, exercise hands-on ability, and develop intelligence. Toy use.

Preferably, the handle is provided with anti-slip lines, and the user can hold the handle stably during use without slipping.

Beneficial effect:

The utility model adopts the above-mentioned technical scheme to provide a multi-purpose household screwdriver, which includes a handle, a knife rod sleeved in the handle, a screwdriver set at the front end of the knife bar, and a crank slider mechanism set at the rear end of the knife bar to drive the knife bar to rotate. , novel shape, simple structure, when you need to use a screwdriver, you only need to turn the rotating wheel, through the rotating wheel to drive the crank slider mechanism to achieve reciprocating motion, so that the knife rod can rotate, and then the screw can be installed or used in the maintenance of household equipment Disassembly, or drilling work such as maintenance and maintenance of wooden boards, is a mechanical device that integrates toys, handicrafts and maintenance tools. It has novel shape, convenient operation, simple structure and low price.
