Detailed description of the invention

For making the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with detailed description of the invention also with reference to accompanying drawing, the utility model is further described.Should be appreciated that, these describe just exemplary, and do not really want to limit scope of the present utility model.In addition, in the following description, the description to known features and technology is eliminated, to avoid unnecessarily obscuring concept of the present utility model.

Refer to Fig. 1-4, the dull and stereotyped spanner of one that the utility model embodiment provides, comprise spanner 1 and with handle 2.The side of spanner 1 is provided with combined mouth 11, and combined mouth 11 runs through end face and the bottom surface of spanner 1.Handle 2 comprises first handle section 22, second handle section 24 and combined cover 26.Second handle section 24 comprises openend and the holding end relative with openend.The openend of second handle section 24 is provided with the receiving space 25 extended to holding end.First handle section 22 comprises link and the insertion end relative with link, and the link of first handle section 22 is connected with spanner 1, and the insertion end of first handle section 22 is inserted in the receiving space 25 of second handle section 24 slidably from the openend of second handle section 24.The compartment of terrain, openend of second handle section 24 is extended multiple around receiving space 25 and against the intermediate plate 28 of first handle section 22.The outer wall of combined cover 26 is provided with friction section 266(such as screw thread, projection or decorative pattern), combined cover 26 is set in first handle section 22, and is movable to be set in and multiple intermediate plate 28 oppressed by multiple intermediate plate 28 clamps first handle section 22.It should be noted that, combined cover 26 is arranged friction section 266 and handled easily person can move combined cover 26.

Concrete, in the present embodiment, combined cover 26 comprises little head end 260 and the stub end 262 relative with little head end 260, little head end 260 comparatively stub end 262 closer to spanner 1, the size of the internal diameter of little head end 260 is less than the size of the external diameter of the cylinder at multiple intermediate plate 28 place, the size of the internal diameter of stub end 262 is greater than the size of the external diameter of the cylinder at multiple intermediate plate 28 place, make little head end 260 oppress multiple intermediate plate 28 when being moved into and being set on multiple intermediate plate 28 and clamp first handle section 22, first handle section 22 is made to be fixedly connected with (i.e. first handle section 22 and second handle section 24 can not relative sliding) with second handle section 24, be set in first handle section 22 when the little head end 260 of combined cover 26 is moved into, first handle section 22 is unclamped by multiple intermediate plate 28, make first handle section 22 and second handle section 24 can relative sliding, thus the size of handle 2 can be changed, and then reach the object of the versatility strengthening dull and stereotyped spanner of the present utility model.

In the present embodiment, first handle section 22 and second handle section 24 are all in cylindric, and combined cover 26, in cone shape, so arranges and handled easily personnel can move combined cover 26.

In the present embodiment, the end face of each intermediate plate 28 is provided with external screw thread 280, be provided with the internal thread 264 coordinated with external screw thread 280 in combined cover 26, so arrange and combined cover 26 can be made to be threaded with intermediate plate 28, thus hold tighter by first handle section 22 can to the larger oppressive force of multiple intermediate plates 28.

Operating personnel are at use dull and stereotyped spanner of the present utility model, if the length of handle 2 meets the user demand of operating personnel just, and first handle section 22 and second handle 2 can relative slidings, operating personnel then by screw combined cover 26 make the little head end 260 of combined cover 26 be screwed to multiple intermediate plate 28 threaded engagement, be fixedly connected with second handle section 24 to make first handle section 22, thus the length of handle 2 is fixed, so that operator uses, if the length of handle 2 can not meet the user demand of operating personnel, and first handle section 22 and second handle 2 cannot relative slidings, then logically screw combined cover 26 and make the little head end 260 of combined cover 26 be set in first handle section 22, to make first handle section 22 and second handle section 24 can relative sliding, now operator can adjust the length of handle 2, when the length of handle 2 be adjusted to can meet operator's demand time, operator can screw combined cover 26 makes multiple intermediate plate 28 clamp first handle section 22, first handle section 22 is fixedly connected with second handle section 24, so that operator uses.

In the present embodiment, each intermediate plate 28 is arc-like sheet, to increase the contact area of intermediate plate 28 and first handle section 22, so that intermediate plate 28 clamps first handle section 22.

In the present embodiment, first handle section 22 is one-body molded with spanner 1, to strengthen the structural strength of dull and stereotyped spanner of the present utility model.

In the present embodiment, the outer wall of second handle section 24 is convexly equipped with the spacing flange 244 of the first spacing flange 244, first and can, against combined cover 26, with the stub end 262 of blocking junction trap 26, avoids combined cover 26 from landing second handle section 24.

In the present embodiment, the openend of second handle section 24 extends internally the spacing flange 246 of formation second, and the insertion end of first handle section 22 is provided with the projection 220 that flange 246 spacing with second coordinates, and comes off in second handle section 24 to avoid first handle section 22.

In the present embodiment, the material of spanner 1, combined cover 26, first handle section 22 and second handle section 24 is metal, to strengthen the structural strength of dull and stereotyped spanner of the present utility model.

In the present embodiment, the size of the combined mouth 11 of spanner 1 is unadjustable, certainly, in other embodiments, survivor of a murder attempt's combined mouth that the combined mouth 11 of spanner 1 can regulate for size, when survivor of a murder attempt's combined mouth that the combined mouth 11 of spanner 1 can regulate for size, the structure of spanner 1 is identical with the structure with survivor of a murder attempt's spanner of the prior art, does not repeat them here.

The beneficial effects of the utility model: dull and stereotyped spanner of the present utility model, by handle 2 is arranged to first handle section 22, second handle section 24 and the combined cover 26 be set in movably in first handle section 22, in the insertion end removable insertion second handle section 24 of first handle section 22, and compartment of terrain arranges multiple intermediate plate 28 coordinated with combined cover 26 on the openend of second handle section 24, make operating personnel can by mobile combined cover 26 make combined cover 26 sheathed or away from multiple intermediate plate 28 to clamp first handle section 22 or first handle section 22 unclamped, when first handle section 22 is unclamped by multiple intermediate plate 28, first handle section 22 can move relative to second handle section 24, to adjust the length of handle 2, the length of handle 2 be adjusted to meet operator's demand time, can move combined cover 26 makes multiple intermediate plate 28 clamp first handle section 22, thus first handle section 22 is fixedly connected with second handle section 24, handled easily person uses, and enhances the versatility of dull and stereotyped spanner.

In addition, the combined cover 26 of dull and stereotyped spanner of the present utility model arranges friction section 266 and handled easily personnel can move combined cover 26.

The foregoing is only preferred embodiment of the present utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacements, improvement etc., all should be included within scope that the utility model protects.
