[0003] Although the above-mentioned prior art can achieve control and change the rotation operation direction of the ratchet member 91 by means of the rotation switch of the reversing switch 94, it still has its shortcomings, for example: the formation of the ratchet wrench 90 needs to be based on the ratchet wrench 90. The front end of the reversing switch 94 is provided with a first spring 95 and a resisting cap 96 for interlocking the locking member 93, and a second spring 97 and a steel ball 98 are arranged at the rear end of the reversing switch 94 for producing abutment. Positioning, due to its many components, will lead to cumbersome and time-consuming assembly operations, which is not an ideal composition design

The invention provides a braking structure of a ratchet wrench. The braking structure of the ratchet wrench comprises a ratchet wrench, a ratchet drive member, a locking and dragging member and a change over switch. The ratchet wrench comprises a head portion having a first containing portion, a second containing portion and a third containing portion, and the third containing portion is provided with a rear end wall. The ratchet drive member is located in the first containing portion, and the ratchet drive member has an outside tooth portion. The locking and dragging member is arranged in the second containing portion, the front end face of the locking and dragging member is provided with a tooth portion, and the rear end face is provided with an against groove. The change over switch comprises a drive portion, the drive portion is provided with a containing hole and disposed in the third containing portion. An against spring penetrates the containing hole, an against portion at the front end of the against spring presses against the against groove, an against portion at the rear end presses against the rear end wall of the third containing portion. By adopting the simple structure, the ratchet wrench can be controlled, and operation directions can be changed and rotated, good convenience and economic benefits in manufacture and assemble can be achieved.
Description
technical field [0001] The invention relates to a ratchet wrench structure, in particular to a ratchet wrench braking structure which is convenient for assembly and has economical manufacturing benefits.
