Abstract
The utility model relates to a dual-purpose spanner with four opens which belongs to the technical field of hardware tools. One end of a handle of the dual-purpose wrench with four opens is provided with two different specification dimensions of double offset ring spanners with single end and the other end of the handle is provided with two single open end spanners, wherein, the spacing of the parallel opening surfaces is unequal. In addition, the number of the specification dimensions corresponding to a spanner opening is marked on the handle.
Description
The utility model relates to a kind of novel manual hardware ﹠ tools four-hole root circle combination wrenches.
The combination wrenches of prior art, one end of its handle is identical with single-end spanner, the other end is identical with the single head double offset ring spanner, its two ends can only be suitable for a kind of fastening, dismounting of hexagon-headed bolt (nut) of specification, because of hexagon-headed bolt (nut) specification has tens kinds, also with regard to tens of the corresponding combination wrenches of being furnished with all size, produce thus that volume is big, Heavy Weight, defective that price is high, cause inconvenience for user and carrier.
The purpose of this utility model is the defective at above-mentioned existence, proposes the round combination wrenches of a kind of novel four-hole root easy to use, high efficiency.
Technical solution of the present utility model:
Four-hole root circle combination wrenches is pulled by handle and two ends four and mouthful is formed, it mouthful is the ring gear that inwall is equipped with 12 identical separately teeth that two of handle one end pull, and the size of the ring gear internal diameter of two ten bidentates is that each is unequal, wherein an end face of pulling mouth is folded mutually with another end face of pulling mouth, their addendum angle is 150 °, dedendum angle is 120 °, and each dedendum angle is made as arc surface shape, the arc surface shape two ends and two flank of tooth join, it mouthful is two parallel open that two of the handle other end pull, wherein an one side of pulling mouth is folded mutually with another one side of pulling mouth, the spacing of their parallel actinal surfaces separately is unequal, and it mouthful is an integral body ° that handle and two ends four pull
Handle is provided with four number numbers of pulling mouthful corresponding specification with two ends.
Advantage of the present utility model:
The novel structure science unites two into one the spanner of prior art, and promptly one many usefulness, improves one times of function, and materials are economized, cost is low, volume is little, in light weight, easy to use and carry.
Accompanying drawing is the utility model schematic perspective view.
Among the figure 1 is handle, the 2, the 3rd, and plum blossom is pulled mouth, and the 4, the 5th, the open spanner mouth.
Further describe technical solution of the present utility model below in conjunction with accompanying drawing:
Four-hole root circle combination wrenches pulls mouthfuls 2 by handle 1 and two ends four, 3,4,5 form, one end of handle 1 is pulled mouth 2, the 3rd, inwall is equipped with the ring gear of 12 identical separately teeth, and the size of the ring gear inside diameter D of two ten bidentates is that each is unequal, the end face of pulling mouth 2 is folded mutually with 3 end face, their addendum angle α is 150 °, dedendum angle β is 120 °, and each dedendum angle β is made as arc surface shape 6, arc surface shape 6 two ends and two flank of tooth join, the other end of handle 1 is pulled mouth 4,5 is two parallel open, the one side of pulling mouth 4 is folded mutually with 5 one side, the spacing of their parallel actinal surfaces separately is unequal, pulls mouth 2 for four of handle 1 and two ends, 3,4,5 is an integral body.Handle 1 is provided with four number numbers of pulling mouthful 2,3,4,5 corresponding specifications with two ends.
Use of the present utility model:
Four-hole root circle combination wrenches uses identical with the combination wrenches of prior art, the hexagon-headed bolt (nut) that only needs during use to pull mouthful with the same size size is nested, just can be fastening, dismounting, the specification that refers to here is that across flats's size of hexagon-headed bolt is pulled a mouthful size with the spacing and the plum blossom of pulling mouthful parallel open.
