Detailed description of the invention
Presently in connection with accompanying drawing, this utility model is described in further detail.
Retchet gear type adjustable wrench as shown in Figure 1, including handle 1 and head 2, head 2 lower end is fixed on handle 1, can be the integrated design, upper end includes the fixed part 3 being provided with regular jaw and is provided with the movable part 4 of moving jaw, being provided with ratchet bar 41 bottom movable part 4, the slot form of ratchet bar 41 may be designed as triangle, more specifically right angled triangle.
Referring more specifically to the partial schematic diagram shown in accompanying drawing 2, also include regulating fixing device 5, be arranged on fixed part 3, be positioned at the lower section of ratchet bar 41, including ratchet 51, pivot pin 52, spring 53 and driving lever 54；The bottom of ratchet 51 is removably secured on fixed part 3 by pivot pin 52, spring 53 withstands ratchet 51 from the obliquely downward of ratchet 51, make ratchet 51 top be stuck in the teeth groove of ratchet bar 41, formed and control the unidirectional non-return structure that movable part 4 only can move towards regular jaw direction；Driving lever 54 is arranged on ratchet 51, can be depressed by spring 53 by pressing driving lever 54 band pawl 51, make ratchet 51 top depart from from the teeth groove of ratchet bar 41.
The move mode of movable part 4 can be realized by the such design of chute-guide rail, movable part 4 is provided with chute 42, fixed part 3 is provided with the guide rail 31 matched with chute 42, ratchet bar 41 is arranged on below chute 42, fixed part 3 is provided with the storage tank 32 that can house ratchet bar 41 below guide rail 31, movable part 4 is slided on guide rail 31 by chute 42, ratchet bar 41 moves the most together, and storage tank 32 can play good receiving effect when ratchet bar 41 moves and fixes, i.e. will not hinder the slip of movable part 4, protective action can be functioned well as again.
Further, fixed part 3 can be provided with the mounting groove 6 installing regulation fixing device 5 in the bottom surface of storage tank 32, the longitudinal cross-section of mounting groove 6 is inverted trapezoidal, the i.e. base of upper end is longer, the base of lower end is shorter, its upper end open connects with storage tank 32, the bottom of ratchet 51 is embedded in the corner of side, mounting groove 6 bottom, the shortest base and the angle from regular jaw waist farther out, and spring 53 is fixed on the oblique waist being connected with opposite side turning, i.e. on the waist close to regular jaw, vertical support is in the side of ratchet 51；Ratchet 51 bottom outer surface is set to circular shaft shape, corresponding mounting groove 6 turning is also set to the fillet agreed with therewith, and such design makes the rotation non-resistance of ratchet 51, and circular shaft matches with fillet, increase the mounting groove 6 Area of bearing to ratchet 51 bottom, improve the stability of ratchet 51 work.
This spanner utilizes ratchet ratchet single-direction transmission, the most locked principle, fixes aperture position.Make different teeth groove coordinate with ratchet 51 by mobile ratchet bar 41 and regulate openings of sizes.Relative to the electrodeless regulation of traditional activity spanner, Retchet gear type adjustable wrench has level to regulate openings of sizes for the size employing of conventional nut such that it is able to be quick and precisely adjusted to suitable openings of sizes.Conventional nut and open-end wrench specification such as following table:
| Nut/M | Nipple heads opposite side size S | Open-end wrench specification S |
| M5 | 8 | 8 |
| M6 | 10 | 10 |
| M8 | 13 | 13 |
| M10 | 16 | 16 |
| M12 | 18 | 18 |
| M14 | 21 | 21 |
| M16 | 24 | 24 |
| M18 | 27 | 27 |
| M20 | 30 | 30 |
M5 8 can be selected, M6 10, M8 13, M10 16, M12 18, M14 21, these 7 conventional nut opening sizes of M16 24 regulate target for there being level, design is suitable for the Retchet gear type adjustable wrench of these 7 conventional nuts, i.e. movable part 4 from lateral fixed part 3 near time, ratchet 51 be stuck in different teeth groove the width of jaw L of correspondence be 8,10,13,16,18,21,24mm, wherein width of jaw L is the vertical dimension between regular jaw and moving jaw, the nipple heads opposite side size that can mate.As needed expanded scope, only ratchet bar 41 teeth groove number need to be increased.
In use, ratchet 51 is stuck in teeth groove under the elastic force effect of spring 53, and ratchet 51 and teeth groove are in unidirectional locked state, can normally use.When opening is turned down by needs, directly movable part 4 is promoted towards regular jaw side, under the effect of motive force, produce between teeth groove and ratchet 51 and slide, drive ratchet bar 41 towards regular jaw 3 one side shifting.When opening is tuned up by needs, by pressing driving lever 54 band pawl 51, spring 53 need to be depressed, so that ratchet 51 top departs from from the teeth groove of ratchet bar 41, then push out moving jaw to suitable size.
Below being only preferred implementation of the present utility model, protection domain of the present utility model is not limited merely to above-described embodiment, and all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model.It should be pointed out that, for those skilled in the art, without departing from the some improvements and modifications under this utility model principle premise, should be regarded as protection domain of the present utility model.
