Abstract

The utility model discloses an adjustable spanner, comprising an adjustable clamp head (1), a fixed clamp head (2), a regulating knob (3)and a handle (6), the regulation knob (3) is arranged on the fixed clamp head (2) by a centre shaft, the adjustable clamp (1) is connected with the regulation knob (3) by screw connection; the utility model also comprises a ratchet (4) and an outer ring (5). A chute (10) arranged on the inner side of the outer ring (5) is provided with teeth (7) inside, the ratchet (4) is arranged on the fixed clamp head (2), and the outer ring (5) covers the adjustable clamp head (1) is fixed outside the fixed clamp head (2); the ratchet (4) is connected with the teeth (7), and the handle (6) is fixed to the outer ring (5). The utility model has the advantages that a clamp head is fastened to screws, the spanner which is not necessarily taken off repeatedly can continuously loose or tight the screws, and the working efficiency of an operating staff is highly improved.

Description

A kind of monkey wrench

Technical field

The utility model relates to the repair outfit field, more particularly relates to a kind of monkey wrench.

Background technology

At present, the monkey wrench that people use always is all by handle, fixed pliers head, movable binding clip be used for the adjusting knob of adjusting activity binding clip and form, in use, jaw is adjusted to the back parbuckle screw that just can be used for of required size, but when the screw of degree of tightness space smaller part, when spanner moves to the chance barrier, just must earlier spanner be extracted out, again spanner is sent into and blocked screw and carry out work once more, bring inconvenience very, also reduce operating efficiency simultaneously greatly to use.

The utility model content

The utility model is exactly the monkey wrench that continuous operation of a kind of energy and high efficiency are provided in order to solve the problems of the technologies described above.

The technical scheme that the utility model adopts in order to solve the problems of the technologies described above is as follows:

A kind of monkey wrench, comprise handle 6, fixed pliers head 2, movable binding clip 1 and adjusting knob 3, adjusting knob 3 is installed on the fixed pliers head 2 by axis, and movable binding clip 1 is threaded with adjusting knob 3, and it also has ratchet 4 and outer shroud 5, have chute 10 in outer shroud 5 inboards, be provided with tooth 7 in chute 10, ratchet 4 is installed on the fixed pliers head 2, and outer shroud 5 is enclosed within outside movable binding clip 1 and the fixed pliers head 2, described ratchet 4 contacts with tooth 7, and handle 6 is fixed on the outer shroud 5.

Described ratchet 4 is paired being installed on the fixed pliers head 2, and contacts with tooth 7 respectively.

It also has and the corresponding to jig 8 of the radian of outer shroud 5, has the bayonet socket 9 that adapts with jig 8 on described outer shroud 5, and an end of jig 8 and an end of bayonet socket 9 are hinged, and the other end of the other end of jig 8 and bayonet socket 9 flexibly connects.

It is after being stuck in binding clip on the screw that the utility model adopts the beneficial effect that technique scheme reached, and does not need the frequent spanner that takes off, and can be continuous carry out pine or tight screw, thereby improved staff's operating efficiency greatly.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

By shown in Figure 1, a kind of monkey wrench, comprise handle 6, fixed pliers head 2, movable binding clip 1 and adjusting knob 3, adjusting knob 3 is installed on the fixed pliers head 2 by axis, movable binding clip 1 is threaded with adjusting knob 3, said structure and monkey wrench structure of the prior art are roughly the same, it also has ratchet 4 and outer shroud 5, have chute 10 in outer shroud 5 inboards, in chute 10, be provided with tooth 7, ratchet 4 is installed on the fixed pliers head 2, outer shroud 5 is enclosed within outside movable binding clip 1 and the fixed pliers head 2, and ratchet 4 contacts with tooth 7, handle 6 is fixed on the outer shroud 5, because outer shroud 5 inboards have chute 10, make ratchet 4 be positioned at this chute 10, spanner is more firm at work in order to make, can be with ratchet 4 paired being installed on the fixed pliers head 2, and contact with tooth 7 respectively, two ratchets 4 preferably are positioned on the center line, in order to be adapted to the scope of application widely, it also includes and the corresponding to jig 8 of the radian of outer shroud 5, on described outer shroud 5, have the bayonet socket 9 that adapts with jig 8, one end of jig 8 and an end of bayonet socket 9 are hinged, the other end of the other end of jig 8 and bayonet socket 9 flexibly connects, also have and tooth 7 corresponding to teeth in jig 8 inboards, at work, when need can earlier jig 8 being opened, after waiting to block screw when screw is blocked with spanner in the side of screw, again jig 8 is regained with outer shroud and fixed, make the tooth 7 of outer shroud 5 inboards can be continuous, when using the utility model, only need the spanner of pulling back and forth to get final product, and do not need frequent taking-up and insertion, thereby improved operating efficiency greatly.

Claims
