Embodiment Construction
[0009] figure 1 , figure 2 It is a structural diagram of a percussion screwdriver according to the present invention, and its structure includes an inner percussion head 1, a sliding tooth 2, a rotating rod 3, a screwdriver 4, and a slideway 5. In the accompanying drawings of the description: the inner ring of the knocking head 1 is designed clockwise from the B end to the A end with five rings of sliding teeth 2 inclined at 10°. The rotating rod 3 and the screwdriver 4 are integrally formed. Clockwise from end C to end D, there are five slides 5 with an inclination of 10°. The slides 5 can rotate counterclockwise along the sliding teeth 2 to the bottom of the striking head 1.
[0010] Described slideway 5 width 3mm, depth 3mm.
[0011] Described sliding tooth 2 width 2.8mm, height 2.8mm.

The invention relates to a striking type screw driver, mainly comprising a striking head, sliding teeth, a rotary rod, a screw driver and slideways. The striking type screw driver is characterized in that five circles of sliding teeth with 10-degree inclination are clockwise arranged on the inner ring of the striking head from a B end to an A end; the rotary rod and the screw driver are integrally formed; and five circles of slideways with 10-degree inclination are clockwise arranged on the outer diameter of the rotary rod from a C end to a D end, and the slideways can counterclockwise rotate along the sliding teeth to the bottom of the striking head. A user clockwise rotates the rotary rod halfway or for one third way from the bottom of the striking head, the palm laterally holds the striking head so that the screw driver head is abutted against a screw, and the other hand strikes the striking head with an iron hammer, the rotary rod drives the screw driver to counterclockwise rotate under the action of the impact force, and the screw is unscrewed.
Description
technical field [0001] The invention relates to a disassembly tool, in particular to a percussion screwdriver. Background technique [0002] Because many screws have not been dismantled or rusted for a long time, it is difficult to disassemble them with a conventional screwdriver, which causes inconvenience to maintenance work. Contents of the invention [0003] The object of the present invention is to provide a percussion type screwdriver, which has the function of percussing and loosening screws with too much adhesion. [0004] The present invention is realized by the following technical scheme: the percussion screwdriver is mainly composed of a percussion head, a sliding tooth, a rotating rod, a screwdriver and a slideway. It is characterized in that: the inner ring of the knocking head is designed with five sliding teeth inclined at 10° clockwise from the B end to the A end. The clockwise design has five slides with a 10° inclination, and the slides can rotate count...
