Description
Technical field
The utility model relates to ratchet spanner.
Background technology
The ratchet wrench driving head of prior art can only be connected in a single direction with sleeve, and namely limited to sleeve and only had the endoporus of one end to be working position, the endoporus of the other end is the connection bit with driving head.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of ratchet spanner, and the driving head of this ratchet spanner can go deep into sleeve inner, using in the middle part of sleeve as connecting hole, for this reason, the utility model provides following technical scheme:
A kind of ratchet spanner, comprise handle body, driving head, keeper, described ratchet spanner also comprises lengthening push rod, and described driving head front portion is the square joint of band extension bar, described driving head is provided with the elongated hole for lengthening push rod insertion, and the length of described extension bar and the degree of depth of hub internal bore match; Described square joint side opening is provided with the hole for keeper turnover, and described lengthening push rod front portion is provided with cam surface; Described lengthening push rod is the mobile turnover being controlled keeper by cam surface in described elongated hole.
On the basis adopting technique scheme, the utility model also can adopt following further technical scheme:
Described lengthening push rod comprises operating portion and is arranged with the body of rod of spring, presses or unclamp described operating portion the body of rod is moved in elongated hole.
Described driving head rear portion is dentate gyrus cylinder, is provided with catch in described handle body, and described catch front end is provided with the ratchet be meshed with dentate gyrus cylinder, the direction that described ratchet regulates driving head to rotate.
Described catch comprises left catch and right catch, and described catch is by turning to plectrum to switch left catch or right catch engages with driving head.
The utility model ratchet spanner can form combination tool with one or more sleeve.Described sleeve comprises cylindrical shell, described cylindrical shell two ends are respectively equipped with the first endoporus and the second endoporus, the connecting hole for connecting ratchet spanner is provided with in the middle part of described cylindrical shell, the bottom of described first endoporus is communicated with by connecting hole with the bottom of the second endoporus, and the bottom of described first endoporus is different from the bottom specification of the second endoporus.
The degree of depth of described first endoporus is identical with the degree of depth of the second endoporus.
Owing to adopting the technical solution of the utility model, the beneficial effects of the utility model are: the length improving driving head makes driving head can enter in the middle part of sleeve, using in the middle part of sleeve as connection bit, the length of the extension bar of driving head is consistent with the bore depth of sleeve, thus makes the endoporus at sleeve two ends all can be used as working position.The utility model combination tool sleeve includes the sleeve of two kinds of different sizes, the carrying amount of half number sleeve in instrument cases can be reduced, namely the weight of instrument cases half is decreased, the public sleeve quality that makes of public connecting hole is lighter simultaneously, moreover decrease the thickness of hub internal bore base material, make entirety lighter and handier.

Detailed description of the invention
As shown in the figure, a kind of ratchet spanner, comprise handle body 1, driving head 2, also comprise keeper 3, lengthen push rod 4, described driving head 2 front portion is the square joint 21 of band extension bar 20, described driving head 2 is provided with the elongated hole 26 for lengthening push rod 4 insertion, and the described length of extension bar 20 and the degree of depth of hub internal bore match; The side opening of described square joint 21 is provided with the hole 5 passed in and out for keeper 3, and described lengthening push rod 4 front portion is provided with cam surface 41; Described lengthening push rod 4 is mobile in described elongated hole coordinates with described hole 5 turnover controlling keeper 3.
Described lengthening push rod 4 comprises operating portion 6 and the body of rod 61, and the described body of rod 61 is arranged with spring 7, and the described body of rod 6 passes handle body 1 top and enters described elongated hole 26, presses or unclamp described operating portion 6 to make 61 to move in elongated hole.
Lengthening push rod 61 moves to cavity by press operating part 6, makes described groove 41 relative with described hole 5, and make keeper 3 can fall into groove from hole 5, now driving head 2 can insert in sleeve.When driving head 2 is inserted into the degree of depth of connection bit in sleeve, unclamp operation portion 6, spring 6 is counter push away lengthen push rod 4 after be moved back into the position before press operating part 6, now stagger and to be ejected by keeper 3 in described groove 41 and described hole 5, keeper 3 is fixed with the connection bit in sleeve, and namely driving head 2 and sleeve are fixed.
Described driving head 2 rear portion is dentate gyrus cylinder 22, is provided with catch 8 in described handle body 1, and described catch front end is provided with the ratchet 81 be meshed with dentate gyrus cylinder 22, the direction that described ratchet regulates driving head to rotate.
Described catch 8 comprises left catch and right catch, and described catch 8 is by turning to plectrum 80 to switch left catch or right catch engages with driving head.
Also comprise packing ring 9, cover plate 94 in a kind of ratchet spanner that the utility model provides, screw 92 and screw 93, and be enclosed within the tapered spring 91 on screw 92.
