Description
Technical field
The present invention relates to a kind of spanner fast and efficiently in the tools range, easy to operate, can increase work efficiency.
Background technology
Spanner commonly used in the market mainly contains following three kinds: shfting wrench, socket wrench and interior combination wrench.Spanner commonly used generally is difficult to reach twists bolt and quickens to twist the bolt purpose under the low-angle situation, though invention along with ratchet spanner, solved the problem of frequent commutation, but ratchet spanner fails to realize to quicken the purpose of twisting the purpose of bolt and twisting bolt under the low-angle situation.
Summary of the invention
The present invention mainly solves spanner also can quicken to twist bolt under the low-angle situation problem, and these two functions are merged together, realizes convenient purpose of efficiently twisting bolt.The present invention compares more advanced on the principle that realizes stubborn bolt with ratchet spanner mechanism, be by the little tooth engagement on tooth on the handle and the gear wheel, and then canine tooth drives the pinion that another can rotate flexibly, two unguiculuses are arranged on this pinion, when stubborn bolt looseness arrives to a certain degree, can utilize the inertia of its spanner built-in system 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 can reach under the low-angle situation, the purpose that also can realize quickening to tighten and unclamp bolt is used flexibly, is saved time, and can improve work efficiency.
Tooth on this handle for tool and gears engaged, when stubborn bolt class workpiece, can maintain static the handle of only need holding with a firm grip, just can twist bolt by one group of transmission, after a work period finishes, only need loose one's grip, handle is subjected to spring force and gets back to original position, can work on, like this, this instrument is when stubborn bolt class workpiece, as long as circulation is held with a firm grip and release handle, so also reached save time, effect efficiently.
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).This instrument can maintain static when stubborn bolt class workpiece only need be held with a firm grip and Panasonic's handle gets final product, handle (1) can rotate around the fixed axis on the frame (11), little tooth engagement on tooth on it and the gear (4), canine tooth on the gear and the engagement of latch device, cingulum on the gear (4) moves latch device (5-1.), unguiculus is connected with chuck assembly on the latch device, the tooth of axis and toothed disc engagement, toothed disc and ratchet device transmission.Unguiculus quick rotation on the latch device, block chuck assembly, two unguiculuses of latch device (5-1.) and then drive the rotation of chuck assembly (5-2.), the rotation of the rotation driven gear dish (8) of axis (7), and then bolt is backed out in the rotation that drives ratchet device (9) again, when treating that bolt looseness arrives to a certain degree, can utilize that the inertia of chuck assembly (5-2.) and axis (7) is very fast backs out bolt.Each handle of only need holding with a firm grip is loosed one's grip and is got final product, and is a work period, repeats above-mentioned can accomplishing the end in view smoothly.
To be more obvious with following specification above purpose of the present invention in conjunction with the following drawings.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples
(1) accompanying drawing introduction
Fig. 1 is an inner assembled sectional view of the present invention
Fig. 2 is the front view of latch device of the present invention (5-1.)
Fig. 3 is the front view of chuck assembly of the present invention (5-2.)
Fig. 4 is the constitutional diagram of latch device (5-1.) and chuck assembly (5-2.)
Fig. 5 is the front view of gear (4)
(2) figure number part: 1 handle, 2 levers, 3 wheel covers, 4 gear 5-are 2. 67 axis of chuck assembly, 8 toothed discs, 9 ratchet devices, 10 springs, 11 frames of latch device 5-1.
The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment, to this instrument advantage that foundation the present invention proposes, its specific embodiment, structure, feature and effect thereof, describe in detail as after.
At first see also Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, 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: the ratchet device (9) of during work the certain specification sleeve being packed into, only need hold with a firm grip handle (1) and lever (2), pinion on the gear driven gear (4) on the handle (1), canine tooth on the gear (4) and latch device (5-1.) engagement also drives the latch high speed rotating, unguiculus on the latch device blocks chuck assembly (5-2.), driving it rotates simultaneously, just realized the high speed rotating of axis (7), the tooth of axis (7) and toothed disc (8) engagement, the quick rotation of driven gear dish (8), toothed disc (8) is connected with ratchet device (9), backs out bolt class workpiece fast thereby drive ratchet device (9).Treat handle (1) to a certain degree loosing one's grip, because the existence of ratchet device (9), the spring (10) that handle (1) is located is subjected to any resistance ground with handle (1) original place of rebounding hardly, more than is a work period, repeats above step and gets final product.This shows that time and effect have been saved in the engagement of handle (1) and gear (4) to a great extent, the instrument of taking down that need not be frequent is adjusted and is commutated, and uses flexible, easy.Latch device (5-1.) is connected with chuck assembly (5-2.), and the inertia that the system that can make full use of rotates is backed out bolt class workpiece fast.Because the existence of ratchet device (9), this spanner does not need frequent commutation, thereby has more saved a lot of times.In addition, this spanner can be motionless when work, and the handle of only need holding with a firm grip gets final product, thereby also can successfully carry out work even can finish under low-angle situation.Comprehensive above two advantages very significantly, this instrument occupies advantage in like product, save time during work, laborsaving, can greatly improve work efficiency.
Above a kind of situation (backing out bolt class workpiece) during described just this tool work, the working condition of (class that tights a bolt workpiece) each mechanism is similar during reverse operation, as long as will wherein install the another side that sleeve on ratchet device (9) is contained in this instrument.During actual the use, sleeve can freely be changed.
The above, it only is preferred embodiments of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the technical scheme scope of the present invention any simple modification, equivalent variations and modification that above embodiment made.
