Description
Technical field
This utility model belongs to hardware & tools, is specifically related to a kind of new and effective screwdriver.
Background technology
In life, the use frequency of screwdriver is significantly high, but general screwdriver efficiency in the process of the turn of the screw is low, speed slow, substantially can not realize the work small space (such as between clamping plate).
In view of this, the new and effective screwdriver of one that this utility model provides, it is not only able to complete screw tightening work fast and efficiently, and adapts to the working environment that space is little.
Summary of the invention
Solve the technical problem that
Main purpose of the present utility model is to provide a kind of new and effective screwdriver, improves rotary rpm and the work efficiency of screwdriver, solves the problem that screwdriver cannot work in narrow space.
Solve the technical scheme that its technical problem adopts
For solving above-mentioned technical problem, this utility model is achieved through the following technical solutions:
A kind of new and effective screwdriver, mainly includes rotary handle (1), small conical gear (9), large conical gear (10) and interior hexagonal groove (13)；It is characterized in that: rotary handle (1) is operated by the interior hexagonal groove (13) on No. 4 axles (17) and No. 3 axle (14) No. 3 axles (14) of control, No. 4 described axles (17) are arranged in front casing (2) by bearing (18), No. 3 described axles (14) are arranged in external screw thread case (3), and the big roller gear (16) being arranged on No. 4 axles (17) engages with the small cylinder gear (15) being arranged on No. 3 axles (14)；No. 2 axles (11) are connected by small conical gear (9) and large conical gear (10) with No. 1 axle (7), No. 2 described axles (11) and No. 1 axle (7) are externally provided with rear casing (5), bearing (8) is interference fitted on No. 1 axle (7), and No. 1 axle (7) upper end is designed to the structure that can coordinate with screw terminal (6)；Hexagonal boss (12) is connected with interior hexagonal groove (13), and external screw thread case (3) and female thread case (4) are threaded connection.
The new and effective screwdriver of described one, wherein: coordinate, by small cylinder gear (15) and big roller gear (16), the effect reaching to accelerate.
The new and effective screwdriver of described one, wherein: by engaging of small conical gear (9) and large conical gear (10), it is possible to make screwdriver in use be not limited to just to screw direction.
Beneficial effect
This utility model in use, when work space is bigger, is operated by rotary handle and makes No. 4 axles rotate, and small cylinder gear 15 reaches the effect of speed-raising with big roller gear 16 after coordinating, make No. 3 axles quickly rotate, directly install screw terminal 6 additional in interior hexagonal groove and work；When work space is narrow and small, namely whole screwdriver can not be made just screw to be operated, coordinate so that moment of torsion is delivered on No. 2 axles by hexagonal boss and interior hexagonal groove, No. 2 axles transfer a torque to No. 1 axle by small conical gear with coordinating of large conical gear, install screw terminal 6 additional and be operated on No. 1 axle.
The new and effective screwdriver of one that this utility model provides is laborsaving, anti-skidding, efficient, and is adapted to the working environment that space is less.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Labelling in figure: 1, rotary handle；2, front casing；3, external screw thread case；4, female thread case；5, rear casing；6, screw terminal；7, No. 1 axle；8, bearing；9, small conical gear；10, large conical gear；11, No. 2 axles；12, hexagonal boss；13, interior hexagonal groove；14, No. 3 axles；15, small cylinder gear；16, big roller gear；17, No. 4 axles；18, bearing.
Detailed description of the invention
Below in conjunction with accompanying drawing and preferred embodiment, to according to the utility model proposes the detailed description of the invention of a kind of new and effective screwdriver, structure, feature and effect thereof, describe in detail as after.
Referring to Fig. 1, a kind of new and effective screwdriver, mainly include rotary handle 1, small conical gear 9, large conical gear 10 and interior hexagonal groove 13；It is characterized in that: the interior hexagonal groove 13 that rotary handle 1 is controlled on No. 3 axles 14 by No. 4 axles 17 and No. 3 axles 14 is operated, described No. 4 axles 17 are arranged in front casing 2 by bearing 18, No. 3 described axles 14 are arranged in external screw thread case 3, and the big roller gear 16 being arranged on No. 4 axles 17 engages with the small cylinder gear 15 being arranged on No. 3 axles 14；No. 2 axles 11 are connected by small conical gear 9 and large conical gear 10 with No. 1 axle 7, and described No. 2 axles 11 and No. 1 axle 7 are externally provided with rear casing 5, and bearing 8 is interference fitted on No. 1 axle 7, and No. 1 axle 7 upper end is designed to the structure that can coordinate with screw terminal 6；Hexagonal boss 12 is connected with interior hexagonal groove 13, and external screw thread case 3 and female thread case 4 are threaded connection.
This utility model is in use, when work space is bigger, being operated by rotary handle 1 and make No. 4 axles 17 rotate, small cylinder gear 15 reaches the effect of speed-raising with big roller gear 16 after coordinating, make No. 3 axles 14 quickly rotate, directly install screw terminal 6 additional in interior hexagonal groove 13 and work；When work space is narrow and small, when whole screwdriver namely can not be made just screw to be operated, coordinate so that moment of torsion is delivered on No. 2 axles 11 by hexagonal boss 12 and interior hexagonal groove 13, No. 2 axles 11 transfer a torque to No. 1 axle 7 by small conical gear 9 with coordinating of large conical gear 10, install screw terminal 6 additional and be operated on No. 1 axle 7.
