Detailed description of the invention

For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and tool This utility model is described in detail by body embodiment.

This utility model embodiment provides a kind of adjustable wrench, as it is shown in figure 1, this adjustable wrench includes: First spanner structure 1 and the second spanner structure 2, this second spanner structure 2 is sliding with this first spanner structure 1 It is dynamically connected.

Wherein, as it is shown in figure 1, the first spanner structure 1 includes: fixing Hubei Province 101 and handle 102.Second Spanner structure 2 includes: movable Hubei Province 201 and cunning on handle 102 length direction of the first spanner structure 1 Dynamic sliding part 202.Form one between movable Hubei Province 201 and fixing Hubei Province 101 and pull mouth 3, along with sliding part 202 Slip on handle 102, this is pulled mouth 3 and becomes big or diminish.

The adjustable wrench that this utility model embodiment provides, by the second spanner structure 2 at the first spanner structure Slip on the handle 102 of 1, regulates the size pulling mouth 3 of adjustable wrench, simple, convenient, Can quickly regulate the size pulling mouth 3, save regulating time.

Preferably, the first spanner structure 1 is formed in one structure, and one end is fixing Hubei Province 101, and the other end is Handle 102, manufacturing process is simple.

Preferably, the second spanner structure 2 is formed in one structure, and one end is movable Hubei Province 201, and the other end is Sliding part 202, manufacturing process is simple.

Further, for the ease of controlling the sliding part 202 slip on handle 102, at sliding part 202 One end away from movable Hubei Province 201 is provided with a regulation switch.Specifically, as it is shown in figure 1, this regulation switchs Including: slide block 4 and an elastomeric element 5.Wherein, slide block 4 is embedded in sliding part 202, with handle 102 recline mutually away from the side in movable Hubei Province 201.Elastomeric element 5 is embedded in sliding part 202, is arranged on Between slide block 4 and sliding part 202, on the width of handle 102, one end of elastomeric element 5 and cunning Block 4 against, the other end and sliding part 202 against.In this utility model embodiment, elastomeric element 5 is preferred For the spring that rigidity is bigger, regulate, to improve, the service life switched.

Wherein, elastomeric element 5 is constantly in compressive state, by the active force of elastomeric element 5 so that sliding Dynamic portion 202 can be stably fixed on a certain position of handle 102, and avoids sliding part 202 arbitrarily to send out Raw slip.When near the direction of handle 102 pressing sliding part 202 away from the one end in movable Hubei Province 201 time ( When pressing the right side of sliding part 202 in Fig. 1 to the left), slide block 4 extrudes elastomeric element 5, movable Hubei Province 201 Move to away from handle 102 direction, the side in the close movable Hubei Province 201 of handle 102 and the second spanner structure 2 Between produce certain distance, now, stir sliding part 202, under the effect of slide block 4, sliding part can be made 202 slide on handle 102.When stopping pressing sliding part 202 is away from the one end in movable Hubei Province 201, bullet Spring restores to the original state, and handle 102 fits, at bullet with the second spanner structure 2 near the side in movable Hubei Province 201 Under the effect of property parts 5, sliding part 202 can be stably fixed to a certain position on handle 102, and It is difficult on handle 102 slide.

Further, it is fixed on the stability of a certain position on handle 102 to improve sliding part 202, as Shown in Fig. 1, handle 102 is provided with the first Access Division 103, sliding part 202 near the side in movable Hubei Province 201 The position reclined mutually near the side in movable Hubei Province 201 with handle 102 is provided with the second Access Division 203.Its In, the second Access Division 203 and the first Access Division 103 clamping.Preferably, the first Access Division 103 is sawtooth Shape structure, the second Access Division 203 is laciniation.

When near the direction of handle 102 pressing sliding part 202 away from the one end in movable Hubei Province 201 time (to In left pressing Fig. 1 during the right side of sliding part 202), slide block 4 extrudes elastomeric element 5, movable Hubei Province 201 to Move away from handle 102 direction, the side in the close movable Hubei Province 201 of handle 102 and the second spanner structure 2 Between produce certain distance, the second Access Division 203 departs from the first Access Division 103, now, stirs slip Portion 202, under the effect of slide block 4, can make sliding part 202 slide on handle 102.When stopping pressing When sliding part 202 is away from the one end in movable Hubei Province 201, spring restores to the original state, the second Access Division 203 and first Access Division 103 clamping, simultaneously under the effect of elastomeric element 5, sliding part 202 can be stably fixed to A certain position on handle 102, and be difficult on handle 102 slide.

Further, sliding part 202 offering a through hole, sliding part 202 is set in handle by through hole Outside 102.

Further, adjustable wrench after a long time use, owing to, under the effect of counteracting force, pulling mouth easy There is small displacement, cause being susceptible to peril when using spanner, therefore, as it is shown in figure 1, In this utility model embodiment, being additionally provided with one at sliding part 202 away from the one end in movable Hubei Province 201 can The locked bolt 6 of movement on the width of handle 102, the end of the screw rod of this locked bolt 6 against One end of elastomeric element 5.Wherein, locked bolt 6 includes: to first rotated near handle 102 direction State and to the second state rotated away from handle 102 direction.When locked bolt 6 is near handle 102 When direction rotates to a certain degree, even if pressing sliding part 202 is away from the one end in movable Hubei Province 201, sliding part 202 still can be firmly fixed on handle 102, pull, to reduce, the probability that mouth 3 is subjected to displacement in use, Improve the safety used.

Further, as it is shown in figure 1, for bolt or the nut of tackling some standard No., handle 102 Having at least one graduation mark 7 in the longitudinal direction, this graduation mark 7 is to arrange according to bolt or nut specification 's.When tightening or unscrew a certain standard No. bolt or nut, by sliding part 202 towards fixing Hubei Province 101 The edge of side aligns with corresponding graduation mark 7, namely when sliding part 202 is towards fixing Hubei Province 101 When the edge of side aligns with wherein graduation mark 7, pull the bolt that the size of mouth 3 is corresponding with graduation mark 7 Or the match specifications of nut, in order to it is rapidly completed regulation.

The adjustable wrench that this utility model embodiment provides, by the second spanner structure 2 at the first spanner structure Slip on the handle 102 of 1, regulates the size pulling mouth 3 of adjustable wrench, simple, convenient, Can quickly regulate the size pulling mouth 3, save regulating time.And the activity that this utility model embodiment provides Spanner has regulation switch and locking function, can improve the safety that spanner uses.Additionally, this adjustable wrench Simple in construction, low cost of manufacture.

Above-described is preferred implementation of the present utility model, it should be pointed out that general for the art For logical personnel, some improvement and profit can also be made under without departing from principle premise described in the utility model Decorations, these improvements and modifications are also in protection domain of the present utility model.
