Abstract
An anti-skid screwdriver is characterized in that a handle is connected with a rod body; a fixing hole is formed at the lower end of the handle; a linear tool bit is formed at the front end of the rod body; and the tool bit is sleeved with a cylindrical anti-skid sleeve with two concentric holes which have different diameters and are formed in the center, wherein, a small round hole sleeves the rod body and a large round hole sleeves the tool bit. When in use, the anti-skid sleeve moves upwards along the rod body and can be inserted into the fixing hole at the lower end of the handle; and when the tool bit is inserted into a straight flute on a screw head, the anti-skid sleeve is put down, and the tool bit and the screw head are sleeved into the large round hole, thereby preventing the tool bit from gliding transversely in the straight flute, and avoiding a circumstance that the tool bit can slide down from the straight flute under force and causes damage to hands and machine parts.
Description
Technical field
The utility model relates to a kind of screwdriver, specifically a kind ofly prevents in operation from screw terminal the screwdriver of landing the straight trough.
Background technology
Straight screwdriver is in operation, and operating personnel are landing the straight trough of regular meeting from screw terminal during cutter head in the process of tighten the screws, and have to find notch again accurately and work on, not only time-consuming but also trouble, unexpected landing also can injure hand and parts when firmly big sometimes.
The utility model content
In order to overcome the easily deficiency of landing the straight trough from screw terminal of straight screwdriver, the utility model provides a kind of on-slip screwdriver, and this trigger can limit the horizontal slippage of driver bit in straight trough, thereby stops its landing.
The utility model solves the technical measures that its technical problem takes, and handle connects shaft, and the front end of shaft is provided with a word cutter head, and the lower end of handle is provided with fixing hole, open semicircle groove on the inwall of fixing hole.On-slip is applied mechanically cylinder and is made, in open the concentric circle holes of two different-diameters, the minor diameter circle hole sleeve is on shaft, and large diameter circle hole sleeve is on cutter head, and the length of its circular hole is greater than the length of cutter head, the outer wall of small sircle hole is less than the outer wall of big hole, and on the outer wall of small sircle hole, flexure strip is installed, when the on-slip cover when shaft moves to fixing hole, the outer wall energy of small sircle hole is inserted in the fixing hole, flexure strip just in time is stuck in the half slot, makes the on-slip cover be fixed on the upper end of shaft.During use, after in the straight trough on the driver bit embedding screw terminal, as long as slightly firmly just the on-slip cover can be put down, the on-slip cover with cutter head in screw terminal is inserted in big hole, no matter be firmly big or small, cutter head is limited in the straight trough by the on-slip cover, and not laterally slippage prevents the straight screwdriver purpose of landing from straight trough in operation thereby reach.
The beneficial effects of the utility model are, avoid straight screwdriver inconvenience that landing causes and trouble the straight trough from screw terminal in use, and are simple in structure.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of on-slip screwdriver.
Among the figure, 1, handle, 2, fixing hole, 3, shaft, 4, flexure strip, 5, the on-slip cover, 6, cutter head, 7, circular groove.
The specific embodiment
In Fig. 1, handle connects shaft 3, opens fixing hole 2 in the lower end of handle, open semicircle groove 7 on the wall of fixing hole, the front end of shaft 3 is made cutter head 6, opens two concentric circle holes that diameter is different in the on-slip cover 5, and top small sircle hole is enclosed within on the shaft 3, and can be in shaft slippage up and down, below big hole be enclosed within on the cutter head, the length of its circular hole is greater than the length of cutter head, at the cylindrical of small sircle hole flexure strip 4 is set, can insert in the fixing hole when on-slip puts to move, flexure strip is stuck in the semicircle orifice.
Claims (3)
1, on-slip screwdriver, handle connect shaft, and handle, at its lower end is established fixing hole, and the front end of shaft is made the in-line cutter head, it is characterized in that: the on-slip cover cylindraceous of the different concentric circle holes of two diameters is opened at center of cover on cutter head.
2, on-slip screwdriver according to claim 1, it is characterized in that: on-slip cover small sircle hole is enclosed within on the shaft, and its cylindrical is provided with flexure strip less than the cylindrical of big hole on cylindrical, the big hole diameter is a bit larger tham the Breadth Maximum of cutter head, and the length of circular hole is greater than the length of cutter head.
3, on-slip screwdriver according to claim 1 is characterized in that: open semicircle groove on the inwall of handle, at its lower end fixing hole.
