The specific embodiment

For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explain the utility model, is not to be used to limit the utility model.

Shown in Fig. 1-6, the utility model provides a kind of universal screwdriver, comprises screwdriver rod 10 and screwdriver handle 20, and screwdriver rod 10 is hollow tube-shape, an end opening of screwdriver rod 10, and the other end is fixedly connected with screwdriver handle 20; Be inserted with a plurality of prisms 11 slidably each other in the opening of screwdriver rod 10; Prism 11 is abutted against flexible parts 12 away from the end of the opening of screwdriver rod 20, and wherein, elastomeric element 12 is fixedly installed on the screwdriver rod 10, and perhaps elastomeric element 12 is fixedly installed on the screwdriver handle 20; Prism 12 flushes near the end of the opening of screwdriver rod 10, is used to form the cutter head of screwdriver.

The screwdriver rod 10 of the universal screwdriver of the utility model includes a plurality of prisms 11; A plurality of prisms 11 abut against the elastomeric element 12 that fixedly installs on screwdriver rod 10 or the screwdriver handle 20; During use, by being pressed on the screw to be operated 30, prism 11 receives the extruding after-contraction of screw end and advances in the screwdriver rod 20 with the prism 11 of this universal screwdriver; Difformity according to the screw end; Contractions in various degree can appear in the prism 11 of corresponding screw end diverse location, form the driver bit shape with screw end form fit, thereby can install screw, operation such as dismounting.The driver bit shape that these prisms 11 form can change arbitrarily according to the screw end shape, for example, shown in Fig. 7 a-Fig. 7 d, can form yi word pattern, cross, hexagon etc.Therefore, it can be applicable to various screw, thereby satisfies demand easy to carry and that raise the efficiency.

Need to prove; Prism 11 in the utility model is little prism; The circumscribed circle diameter that is prism 11 is compared enough little with the circumscribed circle diameter of screwdriver rod 10; So that plug abundant prism 11 in the screwdriver rod 10, improve the precision of the shape of the driver bit that forms, and make the universal screwdriver of the utility model can be applicable to the more screw of polytypic.

In addition; The elastomeric element 12 of the utility model can be arranged in the screwdriver rod 10; Also can be arranged between screwdriver rod 10 and the screwdriver handle 20; Be abutted against setting as long as satisfy the end of elastomeric element 12 and prism 11, and can provide resiliency supported to get final product at prism 11 Shi Weiqi that is squeezed.

Full in order can in screwdriver rod 10, closely to arrange in an orderly manner, the prism 11 of the utility model is preferably hexagonal prism 11.

Further, can be for the ease of the hexagonal prism of the utility model according to the direction sliding extension of expectation, and do not squint, the hexagonal prism 11 of the utility model is provided with the spacing member that slides.As preferred embodiment, the spacing member of the slip of the utility model may be embodied as and is arranged on the convexity 13 and groove 14 that matches on the adjacent hexagonal prism 11.

As preferred implementation; Shown in Fig. 8-11; Six sides of hexagonal prism are followed successively by first side, second side, the 3rd side, the 4th side, the 5th side and the 6th side; Convexity 13 of the utility model and specifically being set to of groove 14: protruding 13 are arranged on first side, the 3rd side and the 5th side of hexagonal prism 11, and groove 14 is arranged on second side, the 4th side and the 6th side of hexagonal prism 11.

During assembling, convexity on the side of each hexagonal prism 11 13 and groove 14 respectively with adjacent hexagonal prism side on groove 14 and protruding 13 couplings, the assembling sketch map of the hexagonal prism of the universal screwdriver of the utility model shown in figure 12.

Shown in figure 13, the screwdriver handle 20 of the universal screwdriver of the utility model is bent structure.Increased bent function, therefore, when using the screwdriver need of work than great dynamics, can bend handle of a knife, the utilization lever principle increases moment, can reduce the application of force simultaneously.

Shown in Figure 14 a-14d; Partial schematic diagram for screwdriver handle; Represented the structural representation of the bent structure of screwdriver handle 20 in detail, from Figure 14 a-14d, can find out that screwdriver handle 20 comprises first 21 and second portion 22; And first 21 is hinged with second portion 22, forms bent structure.

Further; A preferred embodiment as the utility model; First 21 with second portion 22 hinged concrete modes is: the hinged end of first 21 and second portion 22 is respectively arranged with at least one flange 24, is provided with through hole on the flange 24, is inserted with jointed shaft 23 in the through hole.First 21 is hinged through flange 24 with second portion 22.

In order to limit and the fixing bending angle of the screwdriver handle of the universal screwdriver of the utility model, the end of the flange on first 21 or the second portion 22 is provided with the lead angle 25 of cutting sth. askew, shown in Figure 13 c and 13d.

Consider the performance requirement of production cost and each parts of screwdriver, the material operating position of the universal screwdriver of the utility model is specific as follows: elastomeric element 12 is processed by the high elastic rubber material; Prism 11 is processed by steel alloy; Screwdriver handle 20 is processed by the rubber material.

The above-mentioned preferred embodiment that is merely the utility model certainly, can also have other embodiments with further exploration according to actual needs.But, should be clear and definite be that the conversion based on similar above-mentioned or other embodiments with same idea of not explaining out all should be encompassed among the protection domain of the utility model claim.
