Wrench structure

The invention relates to a wrench structure, in particular to a design with a back and forth pulling function, and the structure is simple and not easy to damage.

Press, the wrench tool uses the principle of lever to pull the screw-solid workpiece to achieve the effect of tightening or loosening. It is necessary to assemble and combine the components of various industries by the screw firmware. The general industrial products need to use each due to structural differences. Screws are assembled and fixed with different torsion forces, such as heavy industry such as aviation, shipbuilding and cars. Their components can be assembled with considerable strength to achieve a solid structure, withstand the impact of air pressure and power, while precision industries such as In electronic machinery, components cannot be assembled with excessive torque to ensure accurate operation.

For the conventional ratchet wrench, please refer to the Republic of China Patent No. I336283, "Dial-type reversing ratchet wrench", which is a toggle-type reversing ratchet wrench, which comprises a body, a ratchet member and a two-clamping member. And a reversing piece. One end of the main body is provided with a driving portion, and the driving portion is connected with a holding portion. The driving portion is provided with a first receiving portion and a second receiving portion that is tangent to the first receiving portion. The ratchet member is rotatably disposed in the first receiving portion of the body, and the side wall surface ring of the outer edge of the ratchet member is provided with teeth. The two latching members are respectively slidably disposed at two ends of the second receiving portion of the body, and the two latching members are provided with teeth on one side of the ratchet member, and the top surface of the opposite end of the two latching members A guiding portion is respectively arranged, and an elastic body is arranged between the two clamping members.
