Abstract
The utility model relates to a spanner can be operated by hand or electricity, which comprising a shell, a rotor axis and a retarding mechanism being driven by the rotor axis is arranged at the internal of the shell. The inlet port of the rotor axis is connected with the electric drill collet by a clutch, the outlet port of the retarding mechanism is provided with a sleeve hole. The utility model with compact and reasonable structure can cooperate with electric drill, by borrowing the power of electric drill the sleeve of the spanner can rotate, and the screw can be rapidly tightened or loosened; the operating is convenient that the screw which can not be tightened or loosened by common spanner can be completed.
Description
Technical field
The utility model relates to a kind of spanner, and especially a kind of have manually and the spanner of electric functions.
Background technology
Spanner is the mechanical assembly tool of using always, in various mechanical assembling processes, has many nuts to tighten or to dismantle.And now the most frequently used be exactly back-up wrench, monkey wrench or box spanner, and use these spanners all be that manpower is manual, thereby labour intensity are big, work efficiency is low, and will be subjected to the restriction of nut position, it is little to make spanner promote angle, makes not tighten.But some electric wrenches are also arranged at present, but often its structure is complicated, uses also not very convenient at some places.
Summary of the invention
Technical problem to be solved in the utility model is that a kind of torch wrench simple in structure, flexible and convenient to use will be provided, to tighten or to dismantle nut apace.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this torch wrench, comprise housing, a reducing gear that is provided with a rotating shaft in the housing and drives by this rotating shaft, the input shaft end of rotating shaft is provided with clutch, connect with the electric drill chuck by clutch, the output of reducing gear is provided with sleeve hole.And this reducing gear can be made of a pair of intermeshing bevel gear and worm gear, worm screw, bevel pinion be positioned at rotating shaft axle head and with axle one, worm screw and the coaxial setting of bevel gear wheel.
Compared with prior art, advantage of the present utility model is: this spanner structure is simple, reasonable, with the supporting use of electric drill, by electric drill power, make the sleeve rotation of this spanner, thereby can tighten or unload screw fast, it is flexible to remove stage makeup and costume, the screw that the common wrench of can removing stage makeup and costume is difficult to remove stage makeup and costume.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in the figure, this torch wrench mainly is made of housing 5, rotating shaft 6 and reducing gear, and its shaft 6 is arranged in the housing 5 by bearing, and an end of axle is provided with one " lance tooth " jaw clutch 3, connects with the chuck 2 of electric drill 1 by this clutch 3.And super torque spring 4 is housed on clutch 3, and when torsion was excessive, spring 4 compressed, and clutch 3 separately separates electric drill and spanner automatically, and spanner no longer rotates and plays safety effect.Axle 6 the other end forms a bevel pinion 7, this bevel pinion 7 be fixed on another bevel gear wheel 8 engagements on 12.With this bevel gear wheel 8 coaxial also have a worm screw 9, worm screw 9 and worm gear 10 engagements that are fixed in the housing constitute described reducing gear by intermeshing large and small bevel gear 7,8 and worm gear 10, worm screw 9.And fixedly the axle 12 of bevel gear wheel and worm screw is fixed in the housing 5, is arranged vertically with rotating shaft 6.The output position of worm gear 10 is shaped on plum blossom hole 11, can insert for the shank of interior Hexagonal jacket.
During use, hand is robbed electric drill in elder generation and this spanner is dressed up one, load onto interior Hexagonal jacket then, interior Hexagonal jacket is enclosed within on the required screw of tightening or dismantling, press the switch of electric drill, drive rotating shaft by electric drill and rotate, after reducing gear slows down, rotate by passing through the worm gear drives sleeve, thereby can tighten or unload screw automatically.This spanner can with the supporting use of the electric drill that varies in size.
