Abstract
The invention relates to a holding type efficient wrench, which belongs to tools and is a quick and flexible bolt screwing tool. The holding type efficient wrench is composed of a handle, a knob, a wheel cover, a gear, a latch device, a chuck device, a bearing, a shaft block, a gear disc, a ratchet wheel, a spring, and a rack, and is characterized in that the tool can fix still when the tool is used to screw the bolt type workpieces, only the handle is grasped or loosen. The tooth on the handle is engaged with small tooth on the gear. The canine tooth on the gear is engaged with the latch device. Small claws on the latch device are connected to the chuck device. The tooth of the shaft block is engaged with the gear disc. The gear disc is connected to the ratchet wheel.
Description
Art
The present invention relates to the one spanner fast and efficiently in tools range, easy to operate, can increase work efficiency.
Background technology
Conventional spanner in the market mainly contains following three kinds: shfting wrench, socket wrench and interior combination wrench.Conventional spanner is generally difficult to reach twists bolt and accelerates to twist bolt object in low-angle situation, although along with the invention of ratchet spanner, solve the problem of frequent commutation, but ratchet spanner could not realize accelerating the object of stubborn bolt and in low-angle situation, twisting the object of bolt.
Summary of the invention
The present invention mainly solves the problem that spanner also can accelerate stubborn bolt in low-angle situation, and these two functions is merged together, realizes convenient object of twisting bolt.The present invention is more advanced compared with ratchet spanner mechanism in the principle realizing stubborn bolt, engaged with the little tooth on gear wheel by the tooth on handle, and then canine tooth drives another can the pinion of flexible rotating, this pinion there are two unguiculuses, stubborn bolt looseness to a certain extent time, the inertia of its spanner built-in system can be utilized to back out bolt fast.And do not need rotating spanner in use, as long as hold handle with a firm grip, so this spanner not only has the advantage flexibly of similar ratchet mechanism, even and if can reach in low-angle situation, also can realize accelerating to tighten and the object of unclamping bolt, use flexibly, save time, can work efficiency be improved.
The present invention solves the scheme that its technical problem adopts: as shown in the figure, this instrument is combined by ten parts, handle (1), lever (2), wheel cover (3), gear (4), latch device (5-1.), chuck assembly (5-2.), bearing (6), axis (7), toothed disc (8), ratchet device (9), spring (10), frame (11).During use, hold handle (1) can rotate by the fixed axis in frame (11), tooth on it engages with the little tooth on gear (4), cingulum on gear (4) moves latch device (5-1.), two unguiculuses of latch device (5-1.) and then the rotation of drive chuck assembly (5-2.), the rotation of the rotation driven gear dish (8) of axis (7), and then drive the rotation of ratchet device (9) to back out bolt again, until bolt looseness to a certain extent time, can utilize that the quick rotation of chuck assembly (5-2.) and axis (7) is very fast to be backed out bolt, when loosing one's grip, handle (1) can return to original position when not stressing.Each handle of only need holding with a firm grip is loosed one's grip again, is a work period, repeats above-mentioned can accomplishing the end in view smoothly.
Above object of the present invention will be more obvious with following description in conjunction with the following drawings.

Detailed description of the invention
Below in conjunction with accompanying drawing and preferred embodiment, to this instrument advantage proposed according to the present invention, its detailed description of the invention, structure, feature and effect thereof, be described in detail as follows.
First Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5 is referred to, this instrument is combined by ten parts, and handle (1), lever (2), wheel cover (3), gear (4), latch device (5-1.), chuck assembly (5-2.), bearing (6), axis (7), toothed disc (8), ratchet device (9), spring (10), frame (11) combine.Below according to operation principle, demonstration working condition: during work, certain specification sleeve is loaded ratchet device (9), only need to hold with a firm grip handle (1) and lever (2), the upper pinion of the gear driven gear (4) on handle (1), canine tooth on gear (4) engages with latch device (5-1.) and drives latch high-speed rotation, unguiculus on latch device blocks chuck assembly (5-2.), it is driven to rotate simultaneously, just the high-speed rotation of axis (7) is achieved, the tooth of axis (7) engages with toothed disc (8), the quick rotation of driven gear dish (8), toothed disc (8) is connected with ratchet device (9), thus drive ratchet device (9) to back out bolt class workpiece fast.Treat that handle (1) is loosed one's grip to a certain extent, due to the existence of ratchet device (9), spring (10) with the being subject to any resistance hardly original place that handle (1) is rebounded at handle (1) place, be more than a work period, repeat above step.As can be seen here, handle (1) engages with gear (4), saves time and effect to a great extent, and instrument of need not taking down frequently carries out adjusting and commutating, and uses flexible, easy.The connection of latch device (5-1.) and chuck assembly (5-2.), bolt class workpiece is backed out by inertia that the system that can make full use of rotates fast.Due to the existence of ratchet device (9), this spanner does not need frequent commutation, thus more saves a lot of time.In addition, this spanner operationally can be motionless, handle of only need holding with a firm grip, even thus can complete also successfully can carry out work in low-angle situation.Comprehensive above two advantages very significantly, save time during work, laborsaving, can greatly improve work efficiency.
A kind of situation (backing out bolt class workpiece) above during described just this tool work, during reverse operation, the working condition of (class that tights a bolt workpiece) each mechanism is similar, as long as the wherein sleeve of device on ratchet device (9) is contained in the another side of this instrument.During actual use, sleeve can freely be changed.
The above, it is only preferred embodiments of the present invention, not any pro forma restriction is done to the present invention, every according to technical spirit of the present invention to any simple amendment made for any of the above embodiments, equivalent variations and modification, all still belong within the scope of technical scheme of the present invention.
