The present invention provides a kind of spanners, wherein as Figure 1-Figure 5, the spanner includes the body of rod 1, is set to described The Polygonal wrench mechanism of 1 one end of the body of rod, and it is set to the adjustable spanner mechanism of 1 other end of the body of rod；Wherein,

The Polygonal wrench mechanism includes being set to outside the body of rod 1 to pull mouth 2, and pull more of mouth 2 described in formation It is articulated connection between connecting rod, is additionally provided with inside the body of rod 1 and pulls at least one connecting rod in mouth 2 with described and be connected and being capable of band Between dynamic at least one connecting rod and opposite connecting rod close to or far from push-and-pull unit；

The adjustable spanner mechanism is at least set to the first clamping jaw 3 outside the body of rod 1 and is slippingly set to The second clamping jaw 4 on the body of rod 1, and second clamping jaw 4 can be close to or far from first clamping jaw 3.

Polygonal wrench mechanism is arranged in one end of the body of rod 1 in the present invention, and adjustable spanner mechanism is arranged in the other end, and will be polygonal Wrench mechanism be set as include be articulated and connected by plurality of rods body formed pull mouth 2, when push-and-pull unit pull or push connecting rod when, energy Enable above-mentioned mouth 2 of pulling to squeeze or expand, to effectively realize the adjusting for pulling mouth 2, can adapt in more situations The use of structure.Further, it sets adjustable spanner mechanism to include the first clamping jaw 3 and the second clamping jaw 4, and makes second Clamping jaw 4 can be by sliding close to or far from the first clamping jaw 3, so that it can be effectively according to the difference of practical clamping size It is adjusted.

In a preferred embodiment of the invention, the push-and-pull unit includes and described to pull mouth 2 sequentially connected Drawstring 5, slip ring 6 and the first spring 7, and described first spring, 7 one end is affixed, the other end is connected with the slip ring 6 and being capable of band It is flexible to move the slip ring 6.

In further preferred embodiment, in order to enable the first spring 7 drives the push-and-pull effect of slip ring 6 more preferable, it is described Push-and-pull unit further includes the slide bar 8 being fixedly installed on inside the body of rod 1, and the slip ring 6 and first spring 7 are sheathed on On the outer surface of the slide bar 8.

In one kind more preferably embodiment, it is more convenient for replying stationary state after use in order to enable pulling mouth 2, it is described Pulling mouth 2 includes the first layer and the second layer being sequentially arranged from inside to outside, and by extremely between the first layer and the second layer A few second spring 9 connects.

In another preferred embodiment of the invention, sliding unit, the sliding are provided on second clamping jaw 4 Unit is able to drive second clamping jaw 4 close to or far from first clamping jaw 3.

The setting of the sliding unit can be configured according to actual needs, for example, preferred in one kind of the invention In embodiment, the sliding unit includes at least threaded rod 10, is sleeved on at least partly outer surface of the threaded rod 10 And it is able to drive the spiral button 11 that the threaded rod 10 rotates, and be connected with the threaded rod 10, and be able to drive described the Power transfer unit of two clamping jaws 4 close to or far from first clamping jaw 3.

In another preferred embodiment of the invention, the power transfer unit includes at least to be formed in part of the surface There are the rotation tooth shaft 12 mutually agreed with the screw thread on the threaded rod 10, one end far from the threaded rod 10 in the rotation tooth shaft 12 It is formed with tooth socket 13, the power transfer unit further includes the rack gear for being formed with the conveying trough 14 agreed with 13 phase of tooth socket 15, the extending direction of the rack gear 15 is identical as the glide direction of second clamping jaw 4, and the rack gear 15 and second folder Pawl 4 is connected；

The baffler 16 of protrusion is further fixedly arranged on the rack gear 15, and the baffler 16 is set to second folder Between pawl 4 and the rotation tooth shaft 12.

In further preferred embodiment, the end of first clamping jaw 3 and/or second clamping jaw 4 is additionally provided with The screwdriver head 17 of protrusion；

Elastic reset member is additionally provided on the inner wall of the body of rod 1, and the elastic reset member and the sliding are single Member is connected.

Certainly, in a kind of more preferably embodiment, the elastic reset member is the inner wall for being set to the body of rod 1 On at least one spring.

It is described in a kind of preferred embodiment to enable preferably fixed to adjustable spanner mechanism Also chimeric on the side wall of the body of rod 1 to have clamping plate 18, being recessed inwardly on the clamping plate 18, it is fluted to be formed, and be formed with it is described The screw thread that the outer surface of threaded rod 4 is mutually agreed with.

It will be specifically addressed below.

As shown in Figure 3 and Figure 4, by pushing spiral button 11, spiral button 11 drives threaded rod 10 to rotate, before threaded rod 10 End is a bit of spiral, this spiral drives the spiral part of rotation 12 rear end of tooth shaft, makes to revolve the rotation of tooth shaft 12, rotation 12 front end of tooth shaft Tooth can be rotated with carry-over bar 15, and the effect of baffler 16 is to prevent that spin-ended tooth shaft 12 is collided with the second clamping jaw 4, be connect with rack gear 15 Be the second clamping jaw 4, to realize the adjusting of adjustable spanner train openings size.

As shown in Fig. 2, being the structural schematic diagram of Polygonal wrench mechanism, by extending the first spring 7, to push slip ring 6 travel forward, and slip ring 6 pulls stretching 5 during the motion, and the other end for stretching 5 is connect with four connecting rods for pulling mouth 2, stretch 5 Contraction, make to pull 2 four connecting rods of mouth and travel forward, so that the opening for pulling mouth 2 be made to become smaller, when pushing slip ring 6, make the first spring 7 Compressive state is replied, 5 is stretched and also restores original state, four connecting rods for pulling mouth 2 return to original position under the action of second spring 9 It sets.

Fig. 5 is clamping plate 18, and the effect of this clamping plate 18 is to play clamping action after adjustable spanner machine is fixed, is clamped The conductors inside of 18 intermediate recess of plate has screw thread, and when clamping plate 18 moves inwards, the screw thread of depressed section drives threaded rod 10 A small distance is moved, clamping is played the role of.Clamping plate 18 is decontroled, on both sides under the action of spring, clamping plate 18 is restored to Origin-location.

It is described the prefered embodiments of the present invention in detail above in conjunction with attached drawing, still, the present invention is not limited to above-mentioned realities The detail in mode is applied, within the scope of the technical concept of the present invention, a variety of letters can be carried out to technical solution of the present invention Monotropic type, these simple variants all belong to the scope of protection of the present invention.

It is further to note that specific technical features described in the above specific embodiments, in not lance In the case where shield, can be combined in any appropriate way, in order to avoid unnecessary repetition, the present invention to it is various can No further explanation will be given for the combination of energy.

In addition, various embodiments of the present invention can be combined randomly, as long as it is without prejudice to originally The thought of invention, it should also be regarded as the disclosure of the present invention.
