SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a straight shank strikes O type spanner, can effectively prevent the phenomenon of dropout and thread slipping, and the operation of being convenient for improves work efficiency.

According to the utility model discloses straight shank strikes O type spanner, including straight shank, straight shank can block and put in the draw-in groove of lid, the one end of straight shank is equipped with the axle sleeve, O type through-hole has been seted up on the axle sleeve, the integral key shaft is cup jointed to O type through-hole.

According to the utility model discloses O type spanner is strikeed to straight shank has following beneficial effect at least: when manual dismantlement integral key shaft and lid, cup joint the axle sleeve of this spanner on the integral key shaft to adjust suitable angular position, put the straight shank card in the draw-in groove of lid, then the straight shank is strikeed manually, can make the straight shank use the integral key shaft to carry out clockwise or anticlockwise rotation as the axle center, thereby drive the lid rotation, dismantle the lid. In the process, the wrench is clamped in the clamping groove of the cover, so that the phenomenon of tripping is not easy to occur, the operation safety can be improved, and the working efficiency can be improved.

According to some embodiments of the utility model, the external diameter of axle sleeve is 70mm, the internal diameter of O type through-hole is 45mm, the thickness of axle sleeve is 25 mm. Under the prerequisite of the intensity of guaranteeing the spanner, can make the axle sleeve more adapt to the size of integral key shaft.

According to some embodiments of the invention, the length of the straight shank is 500 mm. The straight handle can be ensured to have enough length, so that the straight handle is convenient for operators to knock, and the influence on the operation caused by overlong straight handle can be avoided.

According to some embodiments of the invention, the cross-section of the stem is hexagonal prism.
