Abstract
The utility model provides an anti-slip screwdriver. A cylindrical anti-slip sleeve is arranged on a rod body of the common straight screwdriver and can slide in the rod body up and down; as the upper part of the anti-slip sleeve is magnetic, and the upper part and the lower part of the rod body of the screwdriver are all magnetic, the anti-slip sleeve can be fixed at the upper end and the lower end of the rod body by utilizing the magnetic property; when in use, after the screwdriver is embedded into a straight flute on a screw head, the anti-slip sleeve is moved downwards, a screwdriver head and the screw head are sheathed in together and are placed into the anti-slip sleeve, so as to stop the screwdriver head from being transversely moved and slid off in the straight flute, thus achieving the purpose of preventing the straight screwdriver from being slid off in the straight flute of a screw in operation.
Description
Affiliated technical field
The utility model relates to a kind of repair outfit, and the screwdriver of on-slip dropping control device specifically is set on a kind of straight screwdriver.
Background technology
Usually, straight screwdriver in use, be rotated operation in the straight trough on the cutter head embedding screw terminal, but cutter head horizontal mobile landing from straight trough often in operation, the notch of having to find accurately again on the screw terminal continues operation, trouble, time-consuming not only, and unexpected landing when firmly big sometimes injure the damage that hand also can cause parts easily.
The utility model content
In order to overcome the easily deficiency of landing from the straight trough of screw of straight screwdriver, the utility model provides a kind of on-slip screwdriver, and this straight screwdriver can prevent in the straight trough landing of operating process from screw.
The utility model solves the technical measures that its technical problem takes, handle, shaft, cutter head are formed the screwdriver body, the on-slip cover is set on shaft, two concentric circles that diameter is different are opened at cylindrical shape on-slip cover center, top circular hole is a bit larger tham screwdriver shaft diameter, and be enclosed within on the shaft, following circular hole, the Breadth Maximum that is a bit larger tham cutter head, in the above circular hole around barrel magnetize and make it have magnetic, also magnetize in the junction of spiral shell knife bar body and handle junction and shaft and cutter head.During use, can upwards rise to magnetic area handle under to on-slip cover, make the magnetic area of on-slip cover attract mutually to fix, not influence the sight line of straight trough on the cutter head embedding screw terminal like this with magnetic area under the handle.After cutter head embeds straight trough, with the on-slip cover to the magnetic area that is displaced downwardly on the cutter head, both attract to fix mutually to make it, the following big hole of on-slip cover just in time is inserted on the screw terminal, screw is put in the on-slip cover, so just limit screwdriver laterally slippage in straight trough, prevent the screwdriver purpose of landing the straight trough from screw terminal in use thereby reach.
The beneficial effects of the utility model are, prevent screwdriver landing from straight trough in use, increase work efficiency, and avoid the unexpected in operation hand that landing causes of screwdriver and the damage of parts.
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, shaft, 3, cutter head, 4, go up magnetic area, 5, the magnetic district, 6, the magnetic cover, 7, the on-slip cover.
The specific embodiment
Handle 1 connects shaft 2 in Fig. 1, make the cutter head 3 of in-line at the head of shaft 2, on-slip cover 7 is made cylindric, and two concentric circle holes that diameter is different are opened at the center, above circle hole sleeve on shaft, and magnetize to handle and make it produce magnetic, following circular hole is a bit larger tham the Breadth Maximum of cutter head, and cutter head 3 can be inserted in it, shaft 2 and handle junction and with the cutter head junction, also magnetize processing, form magnetic area 4,5.
Claims (3)
1, on-slip screwdriver, handle connects shaft, and the head of shaft connects the in-line cutter head, it is characterized in that: round barrel shape on-slip cover is set on shaft.
2, on-slip screwdriver according to claim 1, it is characterized in that: two concentric circle holes that diameter is different are opened at on-slip cover cylindraceous center, top circular hole is a bit larger tham the shaft diameter, and be enclosed within on the shaft, and magnetize processing around the circular hole in the above, make it produce the Breadth Maximum that circular hole below magnetic is a bit larger tham cutter head.
3, on-slip screwdriver according to claim 1 is characterized in that: magnetize processing at screwdriver shaft and handle junction and shaft and cutter head junction, make it produce magnetic.
