Description
Technical field
The utility model relates to a kind of instrument, specifically a kind of screwdriver.
Background technology
Screwdriver is one of instrument that is used for by fastening or dismounting screw, but in the process of holding screw nail, screw is merely the contact instability with screwdriver and is connected, and has the situation that causes screw and screwdriver to be thrown off because of the application of force is inhomogeneous.Under unhandy environment such as high-altitude, the screw disengagement can cause user's operating efficiency low.
The utility model content
The purpose of the utility model is to provide a kind of hand-rail type screwdriver, mainly solves to put screw when fastening and be prone to the problem of throwing off with screwdriver.
The technical scheme that its technical problem of the utility model solution is taked is: the hand-rail type screwdriver, and its structure comprises rocking handle, slide bar; Cylindrical shell, spring and screwdriver, described cylindrical shell bottom surface opening; End face is provided with a through hole, and slide bar is slidingly arranged in the through hole, and described slide bar is respectively equipped with a block greater than through-hole diameter at two ends up and down; The slide bar lower end is provided with screwdriver, and the slide bar upper end connects rocking handle; Be provided with spring between the block of said slide bar bottom and the cylindrical shell upper inside wall.
Described screwdriver has magnetic.
The beneficial effect of the utility model is: utilize the constraint of cylindrical shell to screw, make in the fastening process screw be difficult for throwing off with screwdriver, also do not influence operation even the application of force is inhomogeneous, reduce user's working strength, increase work efficiency.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the schematic top plan view of Fig. 1.
Among the figure: 1 rocking handle, 2 slide bars, 3 through holes, 4 cylindrical shells, 5 springs, 6 blocks, 7 screwdrivers, 8 screws.
The specific embodiment
Like Fig. 1, shown in Figure 2.The hand-rail type screwdriver, its structure comprises rocking handle 1, slide bar 2; Cylindrical shell 4, spring 5 and screwdriver 7, described cylindrical shell 4 bottom surface openings; End face is provided with a through hole 3, and slide bar 2 is slidingly arranged in the through hole 3, and described slide bar 2 is respectively equipped with a block 6 greater than through hole 3 diameters at two ends up and down; Slide bar 2 lower ends are provided with screwdriver 7, and slide bar 2 upper ends connect rocking handle 1; Be provided with spring 5 between the block 6 of said slide bar 2 bottoms and cylindrical shell 4 upper inside wall.
Described screwdriver 7 has magnetic, can be more firm attracted screw 8, prevent screw 8 landings.
During use, screw 8 is put in the cavity of cylindrical shell 4, the screwdriver 7 that has magnetic can hold the afterbody of screw 8; The head of screw 8 is aimed at restraint location; Rotation crank 1, slide bar 2 drives screw 8 and rotates, and spring 5 applies the pressure that moves ahead through slide bar 2 to screw 8; The sidewall constraint screw 8 of cylindrical shell 4 can only travel forward straight, guarantees that screw 8 screws in assigned address smoothly.
