Abstract
The utility model discloses a cross-type screw driver which comprises a grabbing handle and a working rod which is connected with the lower end of the grabbing handle, wherein a plug-in groove which is fitted with and in clamping connection with the working rod is formed in the lower end face of the grabbing handle, the working rod is composed of a connecting portion on the upper portion and a working portion on the lower portion, four protrusive arrises are evenly distributed on the side wall of the connecting portion in a protruding outward mode, the connecting portion and the protrusive arrises on the side wall of the connecting portion wholly form a cross-type structure, the protrusive arrises extend from the upper end to the lower end of the connecting portion, four clamping grooves are arranged on the side wall of the plug-in groove on the lower end face of the grabbing handle, the four clamping grooves are communicated with the plug-in groove and used for inserting and locating of the protrusive arrises, and a rubber layer is arranged on the side wall of each clamping groove and used for filling a gap between each clamping groove and each protrusive arris. Due to the fact that the portion where the working rod and the grabbing handle of the screw driver is designed into the cross-type structure, contacting area of the working rod and the grabbing handle is greatly increased, and therefore clipping function between the grabbing handle and the working rod is strengthened, difficult weakening disappears, and service life of the screw driver is prolonged effectively.
Description
Technical field
The utility model relates to a kind of hardware ﹠ tools, is specifically related to a kind of cross screwdriver.
Background technology
Screwdriver is a kind ofly to be used for twisting screw to force its hardware ﹠ tools in place; it all is that working beam by lever and lever one end setting consists of; people often can use this instrument in productive life; for the ease of using; lever and working beam are the circular cross-section design; working beam has fixed the connection with lever; movable connection is also arranged; but they all are to offer circular port at lever; it is inner that circular working beam is stuck in this circular port; when the rotation lever, provide twisting resistance by the locking effect between circular port and the working beam.The locking effect of this design is limited, if exert oneself excessive or service time long, after the locking effect weakened extremely easily or disappears between circular port and the working beam, the function of screwdriver also weakened or has disappeared with regard to corresponding, makes troubles to use.
Summary of the invention
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, and a kind of cross screwdriver is provided, and it can solve lever and the not strong problem of working beam locking effect of existing screwdriver, improves screwdriver service life.
The technical scheme that the utility model adopts is: a kind of cross screwdriver, comprise the working beam that lever is connected with the lever lower end, the lower surface of described lever is provided with the inserting groove adaptive with described working beam clamping, described working beam is made of the connecting portion on top and the operate portions of bottom, the sidewall of described connecting portion is evenly distributed with four outwardly fins, the whole formation of the fin of described connecting portion and sidewall thereof decussate texture, and described fin extends to its lower end by the upper end of described connecting portion, the inserting groove sidewall of described lever lower surface is provided with four draw-in grooves that communicate and supply described fin intercalation to locate with it, and described draw-in groove sidewall is provided with the rubber layer of filling draw-in groove and fin gap.
As preferably, the cross section ovalize of described fin.
As preferably, the degree of depth of described draw-in groove is consistent with the degree of depth of described inserting groove.
The beneficial effects of the utility model are: because the utility model is designed to decussate texture with the position that working beam and the lever of screwdriver joins, so that the contacted area of working beam institute lever increases greatly, locking effect between lever and working beam is strengthened, the disappearance that is difficult for weakening, after even lever damages, the also direct cross connecting portion of rotary work bar has increased service life of screwdriver effectively.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is A-A sectional drawing among Fig. 1.
Among the figure: 1, lever; 2, working beam; 21, connecting portion; 22, operate portions; 3, inserting groove; 4, fin; 5, draw-in groove; 6, rubber layer.
The specific embodiment
Below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of cross screwdriver, comprise that lever 1 is connected the working beam 2 that the lower end connects with lever, the lower surface of described lever 1 is provided with the inserting groove 3 adaptive with described working beam 2 clampings, described working beam 2 is made of the connecting portion 21 on top and the operate portions 22 of bottom, the sidewall of described connecting portion 21 is evenly distributed with four outwardly fins 4, the cross section ovalize of described fin 4, the fin 4 whole formation decussate textures of described connecting portion 21 and sidewall thereof, and described fin 4 extends to its lower end by the upper end of described connecting portion 21, inserting groove 3 sidewalls of described lever 1 lower surface are provided with four draw-in grooves 5 that communicate and supply described fin 4 intercalations to locate with it, the degree of depth of described draw-in groove 5 is consistent with the degree of depth of described inserting groove 3, and described draw-in groove 5 sidewalls are provided with the rubber layer 6 of filling draw-in groove 5 and fin 4 gaps.
Because the utility model is designed to decussate texture with the working beam 2 of screwdriver with the position that lever 1 joins, so that 2 levers of working beam, 1 contacted area increases greatly, the locking effect of 2 of lever 1 and working beams is strengthened, the disappearance that is difficult for weakening, after even lever 1 damages, the also direct cross connecting portion 21 of rotary work bar 2 has increased service life of screwdriver effectively.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented with this, the equivalence of namely doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
