Abstract
The utility model discloses an open-ended ratchet wheel wrench, which mainly comprises a handle (1), a ratchet wheel mechanism (2), a ratchet wheel containing groove (3) and a ratchet wheel locking mechanism (4). The ratchet wheel mechanism (2) comprises a ratchet wheel opening portion (21) and a ratchet wheel body portion (22) which form a complete circle after being folded; and the ratchet wheel opening portion (21) is integrally connected with the ratchet wheel body portion (22) through a hinge (5). A ratchet wheel of the ratchet wheel wrench adopts a foldable mechanism, when workpieces to be processed are positioned in a narrow space, an opening of the wrench is inserted in alignment with the workpieces, and the handle is rotated to perform fastening or disassembling operations without repeated displacement. Besides, the open-ended ratchet wheel wrench has simple structure, and is a tool with convenient use.
Description
Technical field:
The utility model relates to a kind of machine tool, a kind of specifically spanner.
Background technology:
Our monkey wrench used in everyday, double offset ring spanner, fork spanner, box spanner etc., a common problem is arranged in the course of the work, exactly after the handle of spanner is pushed to certain position, often because the restriction in space, can not proceed fastening or disassembling section, at this moment just need release spanner from workpiece, again inserting spanner after the contraposition works on, take time and effort so repeatedly, especially when workpiece was in narrower and small and hidden locus, transposition was just difficult more repeatedly; Though common ratchet spanner need not replace repeatedly, need the big ability implementation and operation in space of workpiece periphery.
The utility model content:
In order to solve existing technical problem in the background technology, the utility model provides at small space and still can operate freely, and the open ratchet spanner that need not to replace repeatedly.
For solving the problems of the technologies described above, open ratchet spanner of the present utility model is made up of handle, ratchet mechanism, ratchet storage tank and ratchet retaining mechanism, wherein ratchet mechanism comprises ratchet opening portion and ratchet main part, consist of a complete circle after ratchet opening portion and ratchet main part are involutory, described ratchet opening portion accounts for 1/6 to 1/5 of whole ratchet, and ratchet opening portion and ratchet main part are connected through the hinge together; The upper edge, two side of ratchet mechanism circumferentially is provided with groove; The ratchet storage tank is a C shape, and ratchet storage tank sidewall is provided with pole, and the pole of ratchet storage tank inside extend into the circumferential recess inside of ratchet mechanism; The ratchet retaining mechanism comprises locking tongue, leaf spring, accommodation space, wherein locks tongue and is fixed on the leaf spring with rivet, and the other end of leaf spring is fixed on the wall of accommodation space, and the locking tongue inserts between two ratchets of ratchet; Accommodation space is fixed in the lateral surface of ratchet storage tank or handle and the space that the ratchet storage tank is connected.
The utlity model has following beneficial effect: because of ratchet spanner of the present utility model, but what wherein ratchet adopted is open-and-close mechanism, when pending workpiece is in small space, it is practicable fastening or disassembling section that the opening alignment pieces of spanner is inserted the back rotary handle, need not replace repeatedly, simple to operate, can finish Processing tasks in the short time, be a instrument easy to use.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is ratchet opening portion and the ratchet main body structural representation after involutory.
Fig. 3 is a ratchet storage tank internal structure schematic diagram.
Pole on the groove of 1-handle, 2-ratchet mechanism, 21-ratchet opening portion, 22-ratchet main part, 23-ratchet sidewall, 3-ratchet storage tank, the ccontaining cell wall of 31-ratchet, 4-ratchet retaining mechanism, 41-locking tongue, 42-leaf spring, 43-accommodation space, 5-hinge.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, the utility model open ratchet spanner is mainly by handle 1, ratchet mechanism 2, ratchet storage tank 3 and ratchet retaining mechanism 4 are formed, wherein ratchet mechanism 2 comprises two parts, be respectively ratchet opening portion 21 and ratchet main part 22, as shown in Figure 2, consist of a complete circle after ratchet opening portion 21 and ratchet main part 22 are involutory, during manufacturing a complete circular ratchet being divided into two parts gets final product, wherein ratchet opening portion 21 accounts for 1/6 to 1/5 of whole ratchet, ratchet opening portion 21 links together by hinge 5 with the ratchet main part, can certainly adopt other mode that two parts are coupled together, fixedly connected with an end of ratchet main part 22 as long as satisfy an end of ratchet opening portion 21, another free end can get final product with the folding of ratchet main part; The upper edge, two side of ratchet mechanism 2 circumferentially is provided with groove 23; Ratchet storage tank 3 is a C shape, its internal structure as shown in Figure 3, ratchet storage tank 3 sidewalls are provided with pole 31, after ratchet mechanism 2 is put into ratchet storage tank 3, the pole 23 of ratchet storage tank 3 inside extend into circumferential recess 23 inside of ratchet mechanism 2, so just can make ratchet both can be fixed in ratchet storage tank 3 inside, can make ratchet mechanism 2 again along rotating in a circumferential direction; Ratchet retaining mechanism 4 comprises locking tongue 41, leaf spring 42, accommodation space 43, wherein locking tongue 41 usefulness rivets is fixed on the leaf spring 42, the other end of leaf spring 42 is fixed on the wall of accommodation space 43, locking tongue 41 inserts between two ratchets of ratchet, the inclined-plane direction difference of living in of locking tongue 41, the then rotatable direction difference of ratchet; Accommodation space 43 can be fixed on the lateral surface of ratchet storage tank 3, can certainly be placed in handle 1 and the space that ratchet storage tank 3 is connected, so just need offer accommodation space 43 in handle and ratchet storage tank 3 junctions.
During use workpiece is inserted in the spanner, the fastening or dismounting workpiece of rotary handle when handle rotates to inconvenience more firmly the time, rotates handle in the opposite direction, adjust the position of handle after, continue fastening or disassembling section.
