Problems solved by technology

[0003] Although the above-mentioned ratchet wrench 10 can indeed achieve the uninterrupted effect of continuously turning the nut, since the torx tooth hole 121 of the ratchet wrench 10 is a fixed size specification, if it is necessary to turn a larger or smaller nut , the ratchet wrench 10 is not suitable for use, and it is not convenient to use. In addition, when the ratchet wrench 10 is turned off or the nut is tightened, the wrench body 11 must have a certain turning space, which is enough for the ring 12 to tighten the nut. However, if the space in the on-site workplace is narrow and the turning range of the wrench body 11 is limited, the ratchet wrench 10 will not be able to rotate the nut at this time.

Abstract

The invention discloses a ratchet wrench with an adjustable clamping jaw and a ratchet-driven handle. The ratchet wrench comprises a wrench body, a fluted disc unit, a handle unit, a movable clamping jaw group, a direction control unit and a clamping jaw adjusting unit, wherein the fluted disc unit is provided with a base and a fluted disc. The movable clamping jaw group has a plurality of clamping jaw pieces arranged on the base. The rotary handle unit is meshed with and rotates the fluted disc to drive the clamping jaw pieces to rotate. The direction control unit has two groups of clamping pieces and a control ring. The control ring can be rotated to allow one group of clamping pieces to clamp the fluted disc to control the rotation direction of the clamping jaw pieces. The clamping jaw adjusting unit has an adjusting ring which drives the clamping jaw pieces to move to change the clamping size according to the size of a screw cap, thereby achieving convenient use effect.

Description

technical field [0001] The invention relates to a ratchet wrench, in particular to a ratchet wrench capable of rotating a nut in situ, with adjustable jaws and a ratchet handle capable of adjusting size. Background technique [0002] Referring to Fig. 1, a general ratchet wrench 10 mainly has a wrench body 11, a ring 12 sleeved at the front end of the wrench body 11, a catch block 13 set inside the wrench body 11, and a shaft set on the wrench body. The dial 14 on the body 11 and a protruding element 15 snapped on the dial 14, the inner circumference of the ring 12 is provided with a ring of torx teeth holes 121 for fitting a nut (not shown in the figure), and A plurality of ratchets 122 are arranged on the outer periphery, and a tooth portion 131 which can be engaged with the ratchet 122 of the ring 12 is provided on the front side of the locking block 13, and a protruding member 15 is recessed on the rear side. Push the concave part 132, turn the toggle button 14 left and...
