Quick rotating structure of wrench and its wrench (1)

The present invention relates to a quick-rotating structure of a wrench and a wrench thereof, and more particularly to a structure for quickly rotating a ratchet head on a wrench.

The industry often uses a wrench with a ratchet head to drive the rotating member (screw or nut) to tighten or loosen. The wrench has a function of reciprocating driving in one direction, so when driving the rotating member, it is not necessary to be heavy like a fixed wrench. The joint is engaged with the rotating member, and the working efficiency can be improved when the rotating member is loosened or screwed.

However, when the rotating member has been screwed on the object but there is no resistance, such as the rotation of the sleeve provided by the wrench to engage the rotating member, the wrench cannot produce a one-way rotation of the rotating member. The rotating member will only rotate back and forth with the wrench's pulling. If the operator wants to rotate the rotating member quickly, the rotating member will often be rotated quickly by hand, but the wrench must be rotated and rotated before the hand rotates the rotating member. The detachment of the piece can not directly cause the wrench to directly loosen or tighten the rotating member in the state in which the sleeve is engaged with the rotating member, thereby causing the inconvenience and inefficiency of the wrench to drive the rotating member.
