Abstract
The invention discloses a screw driver, which comprises a tool bit and a cutter bar. A driving cutter bar and a driven cutter bar which are crossed with each other are rotatably matched in stepped holes at two ends of two sleeves respectively; and one end of the driven cutter bar is provided with a slot which is matched with a convex body at a end of the screw driver, while the other end of the driven cutter bar and one end of the driving cutter bar are respectively provided with bevel gears which are meshed with each other, and the other end of the driving cutter bar is provided with a handle. The tool bit of the screw driver is a slotted-type, cross-type, a triangular or polygonal tool bit. Compared with the prior art, the screw driver has the obvious advantages of little space of dismantling screws, convenience in operation and high efficiency.
Description
Technical field:
The present invention relates to a kind of instrument that loads and unloads threaded fastener, particularly a kind of screwdriver.
Background technology:
Common screw driver handle is staight shank, but under some specific condition, such as the elevator system that is formed by centre-hole jack and steel strand wires, steel strand wires need to be stuck in the jack anchor dish by three-clove style anchor cable card, wearing the rib process, the jack place presses the fixing of card screw, relatively more difficult, particularly (such as 250t jack 25 steel strand wires that can shuttle back and forth, at this moment, it is little that the space length between the steel strand wires operates sight line less than 2cm when steel strand wires are many, and finger is difficult for stretching into etc., tightening these screws generally needs about 2 hours, even 3-4 hour, efficient is extremely low.
Summary of the invention:
The purpose of this invention is to provide a kind of high a kind of screwdriver of the little and easy to operate efficient in the densely distributed operating space of screw that is applicable to.
The technical scheme that realizes the object of the invention is, a kind of screwdriver, comprise cutter head and knife bar, it is characterized in that: cross one another active knife bar and driven knife bar are rotatably assorted respectively in the stepped hole at two sleeve two ends, one end of above-mentioned driven knife bar is provided with the groove that the convex body with driver tip matches, one end of the other end of this driven knife bar and active knife bar is respectively equipped with intermeshing bevel gear, and the other end of this active knife bar is provided with handle.The cutter head of described screwdriver is yi word pattern, cross, triangle or polygon cutter head.
The present invention has the high remarkable advantage of dismounting little, the easy to operate efficient in screw space compared with the prior art.
Description of drawings:
Fig. 1 is the structural representation of screwdriver of the present invention.
The specific embodiment:
In conjunction with above-mentioned accompanying drawing the present invention is elaborated.Screwdriver of the present invention is by cutter head 1, cutter head bar and handgrip 6 form, wherein the cutter head bar is two orthogonal actives, from dynamic cutter head bar 5,2 form, above-mentioned master, dead eye in the body of rod of dynamic cutter head bar places respectively sleeve 3, above-mentioned active, be respectively equipped with the bevel gear 4 that is meshed from a termination of dynamic cutter head bar, the other end at the active knife bar is provided with handgrip 6, above-mentioned cutter head from the other end of dynamic cutter head bar can be a word cutter head, the cross cutter head, interior six side's cutter heads or outer six side's cutter heads, the upper end of cutter head is provided with the convex body that minor diameter triangle or polygonal hole with driven knife bar termination match, and this convex body is magnetic.For the ease of the assembling of bearing, cutter head bar and sleeve, sleeve can make two semi-circular sleeves, at bush outer sleeve one hoop, on the two ends plate of hoop the screw thread via hole is set, and with screw, nut the two halves round buss is tightened up bearing outer ring.Above-mentioned driving and driven cutter head bar also can be the oblique setting.
The using method of screwdriver of the present invention in the elevator system of centre-hole jack and steel strand wires composition, when promoting tonnage large (such as 250t), the radical of steel strand wires is 25, the distance between the steel strand wires only has 2cm.The three-clove style card is located on each steel strand wires, the outer peripheral face of this three-clove style card is the up big and down small taper hole that the up big and down small conical surface places jack pad assembly, be provided with screw in the screw thread via hole on the three-clove style card, the screwed hole of taper hole bottom matches on this screw and the above-mentioned jack, when moving down by rotary screw drive three-clove style card, to the center contraction steel strand wires are pressed on the jack pad assembly.But because the distance between steel strand wires only has 2cm, for the screw of steel strand wires the insides, conventional screwdriver can't put in and tighten or shed screw, and sleeve for screw driver diameter of the present invention just can operate less than 2cm, and easy to operate and efficient is higher.
Claims (2)
1. screwdriver, comprise cutter head and knife bar, it is characterized in that: cross one another active knife bar and driven knife bar are rotatably assorted respectively in the stepped hole at two sleeve two ends, one end of above-mentioned driven knife bar is provided with the groove that the convex body with driver tip matches, one end of the other end of this driven knife bar and active knife bar is respectively equipped with intermeshing bevel gear, and the other end of this active knife bar is provided with handle.
2. a kind of screwdriver according to claim 1, it is characterized in that: the cutter head of described screwdriver is yi word pattern, cross, triangle or polygon cutter head.
