Description
Technical field
The invention belongs to mechanical device design fields, in particular with the work-saving device of gear set and lever, and in particular to
A kind of Multi-functional labor-saving screwdriver.
Background technique
After screw generation, screwdriver just comes into being, while also can often see spiral shell in public daily life
The figure of silk knife.Screwdriver has different specifications in different fields, there is a common word or cross in common occasion
Screwdriver, but rotary motion is time-consuming and laborious;Also there is the electric screw used in workload and the biggish occasion of intensity
Knife also has the higher screwdriver of precision (usual small volume) in accurate occasion, but consumes electric energy, and some occasion roots
Originally electric screw driver is not needed.The Multi-functional labor-saving screwdriver of press type Non-energy-consumption is to change traditional hand using mechanical structure
The mode of dynamic rotation or power consumption, realizes the function of the turn of the screw.The Laborsaving screwdriver is pushed into market if realizing, it will be people
Very big economic benefit and environmental benefit are brought with society.
The screwdriver that can be saved working hour, reduce production cost existing at present occurs, such as Chinese Patent Application No.
" a kind of working method for the automatic screwdriver saved working hour, reduce production cost " disclosed in 201610219602.2, it is described
Automatic screwdriver remains traditional mode that can be manually rotated, and only saves the step of screw is placed back in mounting hole, does not change
Become the time-consuming and laborious essence of screwdriver.For another example the electricity of multi-funcitonal wheel gun shaped disclosed in Chinese Patent Application No. 201220153264.7
Dynamic screwdriver, electric screw driver is really strong greatly to be improved work efficiency, but also brings energy consumption, and be equipped with multiple rifles
Head, motor, multiple structures such as gear set, Costco Wholesale is high, and many occasions all do not need electric screw driver, but often because of side
Just it selects to use.Two above patent fail will to save working hour and it is energy saving combine, respectively wherein on the one hand
All it is weak.
Summary of the invention
The electric screw driver that the purpose of the present invention is use under substitution traditional manual screwdriver and partial picture, it can be laborsaving
And the realization the turn of the screw of power saving.
To achieve the above object, the present invention provides a kind of Multi-functional labor-saving screwdriver, including gear set structure, handle, solid
Determine inner casing and shell.It is provided with fixed inner casing in shell, is provided with gear set structure, the gear set structure packet in fixed inner casing
Include the gear for being fixed on handle one end, transmission duplicate gear, the gear shaft engaged with gear is fixed in sliding slot and can only be along
Sliding slot carries out the duplicate gear, the roller gear with extraction axis, the transmission gear engaged with roller gear of translation and own rotation,
The pinion gear of the duplicate gear and the gear wheel engagement of transmission duplicate gear;The pinion gear of transmission duplicate gear is nibbled with gear
It closes.
When above-mentioned duplicate gear rotates clockwise, gear shaft is translatable to transmission gear along the chute and makes the canine tooth of duplicate gear
Wheel is engaged with;Duplicate gear is detached from transmission gear when rotating counterclockwise.
Screwdriver installing port is installed on the extraction axis of above-mentioned roller gear.
When handle is pressurized, band moving gear rotates, and then drives the transmission duplicate gear rotation being engaged with, and is driven duplex-gear
Movement is passed to duplicate gear by engagement by wheel;When being transmitted to duplicate gear, duplicate gear is by thrust, before sliding slot
Into, engaged with transmission gear, and then drive cylindrical gear rotary;Complete the rotation of screwdriver;After loosing one's grip, duplicate gear can be because
It is forced to leave original position, is detached from transmission gear, without allowing screw terminal axis reversely to turn.
Further, there are two fixation inner casing is total to, it can be spliced into a complete inner casing, for fixing gear set axis and handle
Fulcrum is fixed by fixation hole and shell.
Further, totally two, shell are spliced into a complete enclosure by fixed pin, for fix, facilitate operation with
It is beautiful.
Further, handle is equipped with reset spring, after the pressure being applied at handle is removed, reset spring shrinkage band
Fixed handle resets.
Further, the extraction axis both ends of roller gear are separately mounted to there are two screwdriver installing ports, realization tighten and
Unscrew.
Further, screwdriver installing port is suitable for the Multifunction screw edge of a knife on the market.
Further, the extraction shaft mounting hole of roller gear is also cross fixed inner casing and shell.
Compared with prior art, the beneficial effects of the present invention are:
The present invention does not expend any electric energy first, is completed using pure mechanic structure (gear set and lever construction) with one
The screw for determining intensity tightens and back-outs process.Whole process neither expends great effort nor expends any electric energy.
Secondly the present invention for electric screw driver in many occasions the characteristics of wasting one's talent on a petty job, be made that our change
Into in larger workload but not high occasion (such as computer repair) electric screw driver of intensity is wasted one's talent on a petty job a bit.Body of the present invention
Shape is small and exquisite and can realize efficient screw torsion, has biggish applying value in these occasions.
Cost of the present invention is very cheap, only the cost of gear set and shell, and production hour is short while having good work
Make effect, has biggish advantage compared to conventional screw-driver in order and electric screw driver.
