The percussion block teeth are circumferentially evenly equipped with multiple along sleeve body.Multiple percussion block teeth are arranged to ensure one during hammering
Next percussion block teeth are more accessible to the position convenient for hammering after secondary hammering.
The utility model also provides a kind of wrench assembly, including spanner and sleeve, and sleeve includes sleeve body, sleeve body one end
Equipped with the mating portion coordinated with threaded fastener rotation stop, the sleeve body excircle is equipped with to apply active force actuating sleeve
The percussion block teeth of barrel body rotation, the sleeve body are equipped with to connect the connection of spanner relative to the other end of the auxiliary section
Plate, the connecting plate are equipped with the connected structure with the cooperation of the output end rotation stop of spanner.
The connected structure is located at the axial location of the sleeve body.
The connected structure is square hole, cubic prism, hexagonal hole or hexagonal prism, four square tenon spanner of corresponding matching, four
Square hole spanner, six square tenon spanners or hexagonal hole spanner.
The percussion block teeth are circumferentially evenly equipped with multiple along sleeve body.
The spanner is ratchet spanner.Wrench assembly provided by the utility model coordinates ratchet spanner to use with sleeve, exempts from
The trouble of device to hole, fast assembling-disassembling threaded fastener improve working efficiency again when removing rotary screwing thread fastener.
Description of the drawings
Fig. 1 provides the structural schematic diagram of wrench assembly sleeve embodiment 1 for the utility model；
Fig. 2 is the structural schematic diagram of wrench assembly sleeve overlook direction shown in Fig. 1；
In attached drawing：1, block teeth are tapped, 2, connecting plate, 3, sleeve body, 4, connected structure, 5, mating portion.
Specific implementation mode
The embodiment of the utility model is described further below in conjunction with the accompanying drawings.
The utility model provides wrench assembly sleeve embodiment 1：
