Abstract
The utility model relates to a wrench, in particular to a quick-disengaging ratchet wrench. The quick-disengaging ratchet wrench comprises a handle and a wrench head. A ratchet mechanism and a pawl are arranged in the wrench head, the ratchet mechanism is arranged in an installation hole of the wrench head, the tail portion of the wrench head is provided with an inner cavity which is communicated with the installation hole, and the inner cavity penetrates through the left side of the wrench head and the right side of the wrench head. The pawl is arranged in the inner cavity through a hinge pin and meshed with a ratchet in the ratchet mechanism. The handle is an arc-shaped crankshaft with the upward-protruding middle portion. The quick-disengaging ratchet wrench has the advantages that the pawl is of an integral structure, the quick-disengaging ratchet wrench is operated in a push-pull type, and therefore the work efficiency is improved by three times to five times; the meshing face of the pawl and the ratchet is enlarged, the transmission is more powerfully conducted, and therefore the sliding phenomenon can not easily occur; the handle is the arc-shaped crankshaft with the upward-protruding middle portion, and therefore the wrench is more attractive in appearance, a user feels more comfortable when operating the wrench, not only can the wrench be prevented from disengaging in the operation process, but also a hand of the user can be prevented from being hurt, and the wrench can reach the space and corners where a traditional ratchet wrench can not reach.
Description
Technical field
The utility model relates to a kind of spanner, specifically, relates to a kind of fast de-formula ratchet spanner.
Background technology
Ratchet spanner is a kind of conventional hand-operated tools, for rotating bolt or the nut that is placed in narrow or inaccessible position, its primary structure comprises handle and driving end, and described handle and driving end are integral type structure, and ratchet mechanism and ratchet are installed in described driving end; Described ratchet mechanism is arranged in the installing hole of driving end; Ratchet is meshed with the ratchet in ratchet mechanism.The defect that existing ratchet spanner exists is: 1, ratchet is split-type structural, and mode of operation is rotary operation, and work efficiency is low; 2, ratchet little with field of conjugate action ratchet, driving force is little, easily occurs sliding phenomenon; 3, handle is staight shank, and is provided with taper knob in handle outer, during operation, not only easily hurt hand, and taper knob is easy to slippage from handle.
Utility model content
The purpose of this utility model is, provides a kind of fast de-formula ratchet spanner, to solve above-mentioned technical problem.
For achieving the above object, the technical scheme that the utility model adopts is:
A fast de-formula ratchet spanner, comprises handle and driving end, and described handle and driving end are integral type structure, and ratchet mechanism and ratchet are installed in described driving end; Described ratchet mechanism is arranged in the installing hole of driving end; It is characterized in that: the afterbody of described driving end is provided with the inner chamber being connected with installing hole, described inner chamber runs through the left and right sides of driving end; Described ratchet is arranged in inner chamber by bearing pin, and is meshed with the ratchet in ratchet mechanism.
Say further: described handle is the arc crank of middle part epirelief.
Beneficial effect: compared with prior art, the utlity model has following advantage:
1, ratchet is integral type structure, and mode of operation is plug-type operation, and work efficiency improves 3-5 doubly;
2, field of conjugate action ratchet and ratchet increases, and transmission is stronger, is not easy to occur sliding phenomenon;
3, handle is the arc crank of middle part epirelief, and profile is more attractive in appearance, and operating handle is more comfortable, come off, and operating angle changes in the time of not only can preventing from operating, and can avoid hindering hand, can also reach traditional ratchet spanner be beyond one's reach space and angle.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
With reference to Fig. 1, fast de-formula ratchet spanner described in the utility model, comprises handle 1 and driving end 2, and described handle 1 is integral type structure with driving end 2, and described handle 1 is the arc crank of middle part epirelief.
