Abstract

The invention discloses a ratchet spanner, comprising a body, a driving piece, at least one clamping piece, a reversing device and a push device, wherein the reversing device comprises a control piece and a toggling piece; the control piece can be rotatably arranged in an axle hole of the driving piece, one end of the control piece is provided with a clamping part, the push device is arranged in the clamping part and is elastically butted against the positioning part of the clamping piece; the toggling piece is pivoted on one end of the driving piece and is provided with a clamping hole in which the clamping part of the control piece can be held, and the toggling piece can be interlocked with the control piece to rotate. The ratchet spanner of the invention adopts the design of separating the control piece from the toggling piece, so that when being accidentally touched, the toggling piece can not be interlocked with the control piece to move down, and a sleeve barrel combined with the combination part of the driving piece can not be accidentally separated, thereby ensuring the ratchet spanner to be considerably safe and reliable; and the ratchet spanner has the advantages of easy and fast processing, reduced production cost and better structural strength.

Description

technical field [0001] The invention relates to a ratchet wrench, in particular to a ratchet wrench with an improved reversing device. Background technique [0002] Referring to Taiwan Patent Publication No. 235541, a patent case entitled "Improved Structure of Ratchet Wrench", one end of the handle is provided with a driving head, the driving head is provided with an adjustment knob, and a rotating rod is arranged in the driving head, An elastic column is passed through the rotating rod, two clamping blocks are pivoted on the rotating rod, and a pushing groove is respectively provided on the central position of the two clamping blocks relative to the elastic column. The ejecting balls arranged in the rotating rod are pushed against the ejecting grooves, so that the teeth of the locking block are engaged with the teeth of the driving head relative to the wall surface, so that the ratchet wrench can be driven in clockwise and counterclockwise directions. [0003] Since the a...
