Abstract
Provided is a multipurpose screwdriver capable of leading driver rods to rotate. The lower portion of an upper driver rod is T-shaped and contacts with the slope of the upper portion of a lower driver rod to form a transition part for motion form transformation. Linear motion of the upper driver rod can be transformed to rotation of the lower driver rod so that torque is generated, and the multipurpose screwdriver achieves the effects of drilling objects or screwing and unscrewing nuts.
Description
Technical field
The utility model relates to the instrument of rotary screw or object boring, especially to the screw that is difficult for unscrewing it is eased out smoothly.
Background technology
Being exposed to outer screw can cause being connected object because get rusty and glue mutually with screw and be difficult for unscrewing and renew screw throughout the year.At present, there is not the instrument that unscrews screw that is specifically designed to yet.
Summary of the invention
Nut is twisted too tightly or nut gets rusty and be connected the problem that object glues mutually in order to solve, and the utility model provides a kind of multipurpose screwdriver.This screwdriver can not only be finished the common purposes of tightening screw, and can solve owing to screw is twisted too tight or got rusty and causes the problem that is difficult for unscrewing.In addition, this screwdriver also can be used as one and impacts the awl use owing to can produce certain moment of torsion when work, finishes some simple bore operations.
The technical scheme that the utility model adopts is:
Arranging one has externally threaded interior pipe, places interior pipe to make it on same vertical curve on epicone bar and following awl bar.Be provided with a groove part at the epicone bar, at the appropriate location of interior pipe horizontal setting one alignment pin, this alignment pin is arranged in the groove of epicone bar, slides by the linear reciprocation up and down of alignment pin in groove and finishes epicone bar moving up and down in certain limit.T shape is made in the bottom of epicone bar, contacts the transition portion that becomes the forms of motion conversion with the inclined-plane on following awl bar top.Can make the rectilinear motion of epicone bar be converted to down the rotation of awl bar, thereby produce moment of torsion, reach the purpose that unscrews screw.In order to make the following awl bar after the rotation return to initial equilibrium state, under bore the bar outside and twined spring, play the effect that the awl bar is resetted.After resetting, screwdriver can carry out work again again, and so repeatedly, when being screwed down female outer tube, the compressing that the epicone bar is subjected to outer tube is also done vertical motion downwards and blocked up to the pin that is positioned.At this moment, following awl bar is also propped up by the epicone bar, and has reached the limit of position of rotation and can not rotate again.Screwdriver under this state namely is a common screwdriver.
Description of drawings
Fig. 1 is the structural map of multipurpose screwdriver inside.
Among the figure: 1. epicone bar, 2. outer tube, 3. alignment pin, 4. in pipe, 5. spring 6. descends the awl bar, 7. conehead.
The specific embodiment
Referring now to accompanying drawing also in conjunction with the embodiments, the utility model is described and interpreted in detail, drawings and Examples all are the explanations to utility model, rather than to restriction of the present utility model.
At epicone bar (1) groove part is set, appropriate location horizontal setting one alignment pin (3) at interior pipe (4), this alignment pin (3) is arranged in the groove of epicone bar (1), slides by the linear reciprocation up and down of alignment pin in groove and finishes epicone bar (1) moving up and down in certain limit.T shape is made in the bottom of epicone bar (1), following awl bar (6) top beveling, and be in contact with one another, when knocking epicone bar (1), epicone bar (1) is done rectilinear motion straight down, and following awl bar is done and is rotated counterclockwise motion, thereby unscrews screw.Following awl bar (6) is outside to be twined spring (5) is squeezed and produces one and get back to the moment of torsion of original state and act on down the awl bar this moment, makes to bore bar (1) (6) and reset.After resetting, screwdriver can be knocked rotation again again, so repeatedly.When being screwed down female outer tube (2), the compressing that epicone bar (1) is subjected to outer tube (2) is also done vertical motion downwards and is blocked up to the pin that is positioned (3).At this moment, following awl bar (6) is also propped up by epicone bar (1), and has reached the limit of position of rotation and can not rotate again.Screwdriver under this state namely is a common screwdriver.
Claims (2)
1. multipurpose screwdriver, formed by epicone bar, outer tube, alignment pin, interior pipe, spring, following awl bar and conehead, it is characterized in that: female outer tube (2) and externally threaded interior pipe (4), horizontal setting one alignment pin (3) in interior pipe (4), epicone bar (1) and following awl bar (6) place interior pipe (4) to make it on same vertical curve, T shape is made in the bottom of epicone bar (1), contacts the transition portion that becomes the forms of motion conversion with the inclined-plane on following awl bar (6) top.
2. multipurpose screwdriver according to claim 1 is characterized in that: under bore bar (6) outside and twined spring (5), epicone bar (1) and following awl bar (6) can be resetted.
