Abstract
The utility model belongs to a tool for the installation or repair of machines, in particular to a wrench with a telescopic movable wrench head used for the fastening or loosening of screw nuts, screw, etc. The utility model comprises a wrench handle, and a plum blossom wrench head and an open wrench head whose both ends are connected with the wrench handle through the screws or pins. Because the wrench handle of the utility model is design as a telescopic structure, the wrench has the advantages of simple structure, convenient operation and portability. Simultaneously, the length of the wrench handle can be adjusted to add torque.
Description
The utility model belongs to machinery to be installed or repair outfit, in particular for tightening or unclamp the wrench of the telescopic movable wrench of nut, screw etc.
Existing spanner is of a great variety.For example be applicable to the adjustable wrench of different size nut, the centre has the double offset ring spanner of pass ring sealing, and box spanner, hook spanner and double (end) wrench etc.Though above-mentioned spanner is applicable to different occasions, but all there is a common problem in they, the nut that ought be tightened or unclamp exactly, may blocked by other parts, need the wrench translation-angle of spanner and handle is not stuck in and tightens under the situation of other parts or unclamp nut, at this moment above-mentioned various spanners just can't use.For this reason, people have invented a kind of spanner of movable jaw again, though the convertible angle of the spanner of this spanner is carried out work, the length of its handle is fixed, the situation that increases moment at need is next powerless, so this spanner also has certain limitation and influences it and apply.
The utility model improves at this problem, and the handle length that designs a kind of spanner can increase or shorten, and correspondingly moment also increases or reduces, the spanner of telescopic movable spanner simple in structure, easy to use, portable.
The utility model is achieved by following manner: a kind of spanner of telescopic movable spanner, comprise that handle and two ends thereof connect open-end wrench and plum blossom spanner on it by screw or pin, above saidly connect by screw or pin, be to adopt articulated manner, be that open-end wrench and plum blossom spanner can rotate, spanner ability translation-angle is to satisfy different instructions for uses like this.Technical characterictic of the present utility model is that handle is designed to telescopic structure, and it is made up of sleeve pipe and interior wrenching bar and detent mechanism thereof.Wherein wrenching bar is two bodies, it is made up of the wrenching bar of open-end wrench and the wrenching bar of plum blossom spanner, the wrenching bar of short plum blossom spanner is connected on the sleeve pipe by hold-down screw, the length that the wrenching bar of long open-end wrench can be regulated handle by detent mechanism.During use, when needs increase moment, can increase the length of handle, promptly unscrew dog screw the wrenching bar of long open-end wrench is pulled out a segment length, and then tighten up and to use by detent mechanism.
Nut (or screw, screw etc.) diameter that said open-end wrench or plum blossom spanner are tightened or unclamped is below 26 millimeters the time, wrenching bar and cover pipe orifice can adopt circular cross-section, corresponding detent mechanism can be made up of through type detent and the dog screw made on the wrenching bar, and institute's nut diameter of tightening or unclamping is more than 26 millimeters the time, and wrenching bar and cover pipe orifice can adopt the square-section.Corresponding detent mechanism can be made up of several detents of making on hollow dog screw and interior spring and place kick and the wrenching bar, the square-section here mainly is to consider from the structural strength of spanner, because the structural strength of square-section and rigidity are high than circular cross-section, so when tightening larger-diameter nut, wrenching bar and cover pipe orifice should adopt the square-section.
The utility model is compared with prior art, has rational in infrastructure, use and easy to carry, can adjust handle length simultaneously again and increase characteristics such as moment.
Fig. 1 is a schematic appearance of the present utility model.
Fig. 2 is that handle structure of the present utility model adopts circular cross-section and detent mechanism schematic diagram thereof.
Fig. 3 is that handle structure of the present utility model adopts square-section and detent mechanism schematic diagram thereof.
Among the figure: the wrenching bar of the wrenching bar of 1 open-end wrench, 2 pins, 3 snibs, 4 jump rings, 5 open-end wrenches, 6 sleeve pipes, 7 dog screws, 8 through type detents, 9 hold-down screws, 10 plum blossom spanners, 11 plum blossom spanners, 12 hollow dog screws, 13 springs, 14 place kick, 15 detents, 16 square-sections, 17 circular cross-sections.
Most preferred embodiment of the present utility model, as Figure 1-3.A kind of spanner of telescopic movable spanner, comprise open-end wrench 1 and plum blossom spanner 11 that handle and two ends thereof connect on it by screw or pin 2, above saidly connect by screw or pin 2, be meant the employing articulated manner, be that open-end wrench 1 and plum blossom spanner 11 can rotate, spanner 1 or 11 ability translation-angles are to satisfy different instructions for uses like this.Technical characterictic of the present utility model is that handle is designed to telescopic structure, its by sleeve pipe 6 and interior wrenching bar 5 thereof and 10 and detent mechanism form, wherein wrenching bar 5 and 10 is two bodies, it is made up of the wrenching bar 5 of open-end wrench and the wrenching bar 10 of plum blossom spanner, the wrenching bar 10 of short plum blossom spanner is connected on the sleeve pipe 6 by hold-down screw 9, the length that the wrenching bar 5 of long open-end wrench can be regulated handle by detent mechanism, above the wrenching bar 5 of open-end wrench of said length and the wrenching bar 10 of short plum blossom spanner, the two can change opposite design.During use, when needs increase moment, can increase the length of handle, promptly unscrew dog screw 7 wrenching bar 5 of long open-end wrench is pulled out a segment length, and then tighten up and to use by detent mechanism.
Nut (or screw, screw etc.) diameter that said open-end wrench 1 or plum blossom spanner 11 are tightened or unclamped is below 26 millimeters the time, wrenching bar 5 and 10 and sleeve pipe 6 endoporus can adopt circular cross-section 17, corresponding detent mechanism can be made up of through type detent of making on the wrenching bar 8 and dog screw 7, and institute's nut diameter of tightening or unclamping is more than 26 millimeters the time, wrenching bar 5 and 10 and sleeve pipe 6 endoporus can adopt square-section 16.Corresponding detent mechanism can be made up of some detents of making on hollow dog screw 12 and interior spring 13 and place kick 14 and the wrenching bar, the square-section here mainly is to consider from the structural strength of spanner, because the structural strength of square-section and rigidity are high than circular cross-section, so when tightening or unclamp larger-diameter nut, wrenching bar 5 and 10 and sleeve pipe 6 endoporus should adopt the square-section.
