Abstract
The utility model relates to a bi-service screw driver which comprises a first bevel gear and a second bevel gear. Gear shafts of the first bevel gear and the second bevel gear are connected with a first screwing rod and a second screwing rod respectively, the head portion of the first screwing rod forms a rotation head of the screw driver, and the tail portion of the second screwing rod is connected with a screwing handle of the screw driver; the screw driver further comprises an pluggable pin shaft keeping the coaxial connection of the first bevel gear and the second bevel gear, a pin hole matched with the pluggable pin shaft is arranged at the axle center position of the first and the second bevel gear, and a first work position of the bi-service screw driver is formed during the coaxial connection; and a second work position of the bi-service screw driver is formed when the first bevel gear is meshed with the second bevel gear. When the bi-service screw driver is used in a straight mode, the coaxial-connected screwing handle and the screwing head perform control, while the screw driver is used in a bent mode, by the aid of the transmission of the two mutually meshed bevel gears, torsion imposed on the screwing handle is transmitted to the screwing head which forms a right angle with the screwing handle; and the bi-service screw driver has the advantages of being convenient to operate and small in occupied room while used for screwing screws at the bent position.
Description
Technical field
The utility model relates to a kind of hardware & tools, specifically is a kind of dual-purpose screwdriver (screw rotating tool) that can turn.
Background technology
Screwdriver (screw rotating tool) is widely used in daily life and device assembles, the maintenance as a kind of the most frequently used hardware & tools; Its basic form is that a handle adds a bar of screwing that has cutter head (revolving head), comes transmission torsion through turning handle; And then the degree of tightness task of realization screw.
During actual the use, in some occasions, such as the corner, general screwdriver can not be stretched, and can't the bolt of the inside be tightened; Though the many screwdrivers that can turn are arranged in the prior art, such screwdriver structurally all is fixing dead, in case produce, the body of rod just can't stretch, and uses very and bother, during turning handle otherwise the change direction of stopping.
The utility model content
The utility model technical problem to be solved is to provide a kind of and both can turns, and can stretch the dual-purpose screwdriver that use the back again, to replace the original screwdriver that can not turn, and can be more effectively at the edge tighten the screws.
Its technical problem to be solved can be implemented through following technical scheme.
A kind of dual-purpose screwdriver; Its characteristics do; Comprise first bevel gear and second bevel gear, the gear shaft of said first bevel gear connects first bar of screwing, and the gear shaft of said second bevel gear connects second bar of screwing; Said first screw bar head form the head that revolves of this screwdriver, said second screw bar afterbody connect the handle of screwing of this screwdriver; Comprise that also one keeps said first bevel gear and the coaxial plug type bearing pin that is connected of said second bevel gear; The position, axle center of said first bevel gear and second bevel gear is provided with the pin-and-hole that matches with said plug type bearing pin, and said first bevel gear forms first station of this dual-purpose screwdriver when being connected with second bevel gear is coaxial; Form second station of this dual-purpose screwdriver when said first bevel gear and the engagement of second bevel gear.
As the further improvement of present technique scheme, said first bevel gear and second bevel gear are 45 degree bevel gears.
Further improvement as the present technique scheme; Also comprise first axle sleeve and second axle sleeve; Said first axle sleeve is used to locate first under said second station screw bar and/or first bevel gear, and said second axle sleeve is used to locate second under said second station screw bar and/or second bevel gear.
As further improving again of present technique scheme; The first interior angle position that bar and second screws the bar angle of screwing under said second station; Said first axle sleeve is connected with the said second axle sleeve hinge; First position, exterior angle that bar and second screws the bar angle of screwing under said second station, said first axle sleeve is fixedly connected through a right angle keeper with second axle sleeve.
As one of preferred embodiment of the utility model, an end of said plug type bearing pin stretches out the afterbody of the said handle of screwing.
Adopt the dual-purpose screwdriver of technique scheme, not only can turn, can also it be stretched the back and use.Stretch when using the handle of screwing through coaxial connection and control with the head of screwing, and turn when using, then by means of the transmissions of two intermeshing bevel gears, and then the torsion that will be applied on the handle of screwing passes to screw head rectangular with it; Thereby need not stop to change the shortcoming of handle orientations when having avoided existing right-angled bend screwdriver to use.When being used for the turning tighten the screws, has the advantage easy to operate, that space hold is little.

The specific embodiment
To dual-purpose screwdriver shown in Figure 3, have two kinds of stations like Fig. 1, see Fig. 1 and Fig. 2 respectively, station wherein shown in Figure 1 has been illustrated the state that the state that screwdriver integral body is stretched, station shown in Figure 2 have illustrated that then screwdriver is turned.
Referring to Fig. 1, this dual-purpose screwdriver comprises two 45 degree bevel gears 210 and 220; Wherein bevel gear 210 connects one section bar 110 of screwing; Screw the head of bar 110 for revolving 111, and bevel gear 220 connects another section bar 120 of screwing, and the afterbody of the bar 120 of screwing is connected with tightens handle 500.To be that orthohexagonal bearing pin 400 is pluggable be connected in series bevel gear 210 and 220 for cross section; And then keep both coaxial connection; For the ease of bearing pin 400 and bevel gear 210 and 220 be connected, bevel gear 210 and 220 central shaft position are provided with the suitable pin-and-hole of regular hexagon structure with bearing pin 400.One end of bearing pin 400 is serially connected bevel gear 210 and 220; The other end passes the hole of set lever 500 inside; Afterbody stretches out from set lever 500; Through the length of control extension, promptly realize and to plug, and then keep or cancel the connection status of two coaxial connections of bevel gear like this.
As shown in Figure 2, be the signal of the station structure under this screwdriver turn condition, bevel gear 210 and 220 is meshed, bar 110 and 120 relation of meeting at right angles of screwing.Cancel the serial connection of 400 pairs of two bevel gears of bearing pin this moment; In order to locate and the state at the right angle that keeps turning; In bar 110 and 120 the rectangular interior angle positions of screwing, axle sleeve 310 and 320 is used same attachment screw 612 hinges and is connected the position, exterior angle at the right angle; Axle sleeve 310 and 320 is located by connecting by fixed head 620 right angles own; Be the function that fixed head 620 plays a right angle keeper, fix with being connected of this right angle keeper respectively with 320, realized that screwdriver on the whole becomes the state of a stable right angle bent angle through axle sleeve 310.
As shown in Figure 3, through attachment screw being assigned in the different connecting hole 622, realize different status requirements.
To earlier bearing pin 400 be left behind from set lever 500 by stretching when becoming bending when screwdriver, the screw of fixed head 620 is all unscrewed, set positions such as gear,, will become shown in Figure 2 one the screwdriver that can turn round again with screw tightening.
This novel dual-purpose screwdriver that the utility model provides especially can be turned, " screwdriver that can turn " that can both use at angle, corner, limit.
Position relation and interactively (for example coaxial the connection or engagement) through two bevel gears of conversion, the stretching or fully of realization screwdriver.And under engagement, realized the transmission of torsion through the transmission of gear.
