Abstract
Provided is a multifunctional spanner which is formed by sequentially casing a plurality of tubes, outer diameters or inner diameters can be cased into corresponding inner hexahedron-shaped or outer hexahedron-shaped screw caps, and the sections of the tubes are regular hexagon or regular dodecagon, each tube is capable of sliding mutually, and locking devices can be arranged between each tube. The utility model has the advantages of simple structure, convenient usage and carrying or the like.
Description
The utility model relates to a kind of combination wrench.
Existing box spanner and allen wrench respectively are a cover of forming by many, and it uses inconvenience, scatters and disappears easily.
The purpose of this utility model is the deficiency that overcomes existing box spanner and allen wrench, provide a kind of simple in structure, carry and combination wrench easy to use.
The utility model be achieved in that several external diameters or internal diameter can be inserted in corresponding in the cross section of six sides or outer six square nuts be regular hexagon or just dodecagon pipe 1,2,3,4 be nested together successively, can slide mutually between each pipe.Because less outer six square nuts can be chimeric mutually with bigger interior six square nuts, its inner surface of regular hexagon pipe that is nested together successively can be inserted in less outer six square nuts, and adjacent cover and the regular hexagon tube outer surface in it can embed bigger interior six square nuts.
Can establish locking device between each pipe.Locking device can be taked following embodiment: be enclosed within the slit 6 that each inboard tube outer surface has axial non-perforation; Each tube wall that is enclosed within the outside is porose, and pin or steel ball 7 are arranged in the hole.Pin or steel ball protrude the inner surface of each pipe, and after each pipe was chimeric mutually, the pin or the steel ball of protrusion snapped in the slit, though make it have slip to be unlikely to come off; Each pipe has the porose position of the position of slit and tube wall not at same position, is preferably in a relative side.
Can there be depression 11 at two ends, slit bottom surface, and pin or steel ball can have certain radial expansion distortion by spring 8, so that it can be relatively stable when sliding to two ends; Depression 10 also can be arranged, so that each pipe is unlikely to random slip when not using in the middle of the slit.
For increasing its intensity, can establish the combination wrench of two cover different sizes, each overlaps the nut of the corresponding size of space, and the thickness of tube wall will increase and its intensity is improved like this.
For easy to use, the pipe of large-size can be a cover in addition; For reducing weight, its cross section of the pipe of large-size can be positive dodecagon 15.
Can have handle 13 on the outmost pipe 12, and fix, also can take off independent use in case of necessity by the screw 14 and the pipe of its inboard; The inside can be one or six square bars 5.
The utlity model has advantages such as simple in structure, easy to carry.

Fig. 2 is a radial cross-section of the present utility model.
Fig. 3 is the radial cross-section of another embodiment of the utility model.
Fig. 4, Fig. 5 are the embodiment that the utility model tube wall has the locking device in slit and hole respectively.
Fig. 6 is the axial cutaway view of locking device.
Fig. 7 is the embodiment of having handle on the outmost pipe.
Fig. 8 is the axial cutaway view of the embodiment that slit has depression in the locking device.
