Abstract
The utility model belongs to a quick and flexible bolt tightening tool in the category of tools, in particular to a novel high-efficiency wrench. The tool has the following main structure that: a handle is connected with a gear on a shaft, a planetary gear structure is engaged and connected with a gear at the outer side of a bearing sleeve, and an inner ring of the bearing sleeve is fixed with the shaft. In this way, when in use, the utility model not only has advantages similar to those of a ratchet mechanism but also can work with high efficiency under the condition of small angles. The novel high-efficiency wrench mainly can solve the problems of accelerated bolt tightening and two-way bolt tightening of the wrench, combines the two functions together and realizes the aim of tightening bolts conveniently with high efficiency. In the utility model, the principle of realizing the two-way bolt tightening is different from that of a ratchet wrench mechanism, and the aims of tightening the bolts in a two-way mode and regulating the position of the handle are achieved by the engagement and the separation of the handle and the rotating shaft. Meanwhile, the function of tightening the bolts quickly is realized by the acceleration principle of a planetary mechanism. The wrench is convenient and flexible to use, saves time and labor and can enhance the working efficiency.
Description
Affiliated 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 the purpose of quickening to twist bolt and two-way stubborn bolt, though along with the invention of ratchet spanner, solved the problem of two-way stubborn bolt, ratchet spanner fails to realize quickening the purpose of stubborn bolt.
Summary of the invention
The present invention mainly solves the problem that spanner quickens to twist bolt and two-way stubborn bolt, and these two functions are merged together, realizes convenient efficient purpose of twisting bolt.The present invention is different with ratchet spanner mechanism on the principle that realizes two-way stubborn bolt, be by button by fixed handle one end, make the engagement of handle and rotating shaft or separate the purpose that reaches two-way stubborn bolt and regulating handle position, realize twisting fast the function of bolt simultaneously by the acceleration principle of planetary mechanism.Handle is connected with gear on the axle, and the gears engaged in planetary gear construction and the bearing sleeve outside is connected, the inner ring of bearing sleeve and spool fix.This spanner not only has the advantage flexibly of similar ratchet mechanism, and can reach and quicken to tighten and the purpose of unclamping bolt, easy to use, flexible, save time, laborsaving, can improve work efficiency.
The present invention solves the scheme that its technical problem adopts: as shown in the figure, this instrument is combined by six parts, handle (1), axle (2), bearing (3), big sleeve (4), planetary gear construction (5), bearing sleeve (6).Handle (1) can rotate around axle (2), and be fixed together by bearing (3) and following planetary gear construction (5), the inner ring sleeve of bearing sleeve (6) is on axle (2), outer shroud has gear and fixes with sleeve, planetary gear construction (5) can rotate around the inwall (teeth are arranged) of big sleeve (4), and the gears engaged on planetary gear construction (5) and the bearing sleeve (6).During work, there is schematic structure handle (1) inside at spanner, when pressing 1-1. during button, 1-3. axis just in time is stuck between the gear of axle (2), with the hand steered big sleeve (4) of living, drives the motion of three planetary gear constructions (5) below the axle by bearing (3), planetary gear (5) is around the internal motion of big sleeve (4), thereby with the gears engaged on the bearing sleeve (6), drive the sleeve motion, reach the purpose of screwing on or backing out bolt.When handle turns over certain angle or meets with obstruction, press 1-on the lower handle (1) 1. during button, 1-on the handle (1) 3. axis withdraw from the axle (2) gear, turning handle this moment (1) is just no longer stressed, can return arbitrarily angledly,, block the gear of axle on (2) and work on by the time correct position is pressed 1. button of 1-again, be a work period, repeat 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.

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 the Figure of description part, the present invention is mainly by handle (1), axle (2), and bearing (3), big sleeve (4), planetary gear construction (5), bearing sleeve (6) combines.
As Fig. 9, Figure 10, Figure 11, Figure 12 and shown in Figure 13, what demonstrate is the situation of its a kind of work: during work bearing sleeve (6) is enclosed within on the bolt, press the button (1-1.) on the lower handle (1), axis (1-3.) blocks between the gear of axle on (1), at this moment just can drive the rotation of axle (2) by turning handle (1), three pawls on axle (2) and the planetary gear construction (5) are fixed together, planetary gear construction (5) just rotates around the internal tooth of big sleeve (4), thereby the gear that drives bearing sleeve (6) rotates, and at this moment bearing sleeve (6) just can drive the rotation of bolt class workpiece.When handle (1) meets with obstruction or can only move under the low-angle situation, forward certain position to, pressing the button (1-1.) axis (1-3.) again withdraws between the gear of axle (2), rotate arbitrarily under the situation that handle (1) just can arbitrarily angledly not stress, by the time the position that is fit to presses the button (1-1.) again, axis (1-3.) blocks the gear on the axle (2) again, can drive the rotation of axle (2) again, more than be a work period, repeat above step and get final product.Time and effect have been saved in the effect that this shows handle (1) to a great extent, and the instrument of taking down that need not be frequent is adjusted and commutated, and use flexible, easy.Planetary gear construction (5) can increase the rotational angle of bearing sleeve (6), this has shown that further this instrument has the effect that enlarges rotational angle, even also can successfully carry out work thereby can finish under low-angle situation, compare with instruments such as common wrench, the advantage of this instrument is self-evident.Comprehensive above two advantages very significantly, this instrument occupies advantage very significantly in like product, save time during work, laborsaving, can greatly improve work efficiency.
Above a kind of situation (work clockwise) during described just this tool work, the working condition of (counterclockwise) each mechanism is similar during reverse operation, wherein bearing sleeve (6) can freedom about, can use the bearing sleeve of different sizes instead according to actual conditions, but gear on the bearing sleeve and planetary gear construction mesh the size of that part can not changed, thereby convenient production is required.
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.
