Abstract

The utility model discloses a kind of monkey wrench, comprise handle and gear ring, described handle one end is connected with gear ring is side walls hinged, formation one and the opening portion be communicated with inside gear ring on gear ring circumferential side wall, handle one end can be stretched in gear ring along this opening portion, engaging tooth is equipped with handle one end outer surface inside described gear ring, the utility model is easy to operate, this spanner part is few, structure is simple, be convenient to processing and manufacturing, production cost is low, cheap, easy to use, do not limit by connector profile and size, even pipe also can stablize rotation, there will not be slide fastener phenomenon, this patent spanner intelligence just can pull revolving part along rotating forward, its reversely rotate time and revolving part release, spanner reversely rotates and does not bear any torsion, can prevent from oppositely pulling revolving part to damage handle and stretch into end in gear ring, avoid occurring that faulty operation damages the phenomenon of spanner.

Description

Monkey wrench

Technical field

The utility model relates to a kind of spanner, particularly a kind of monkey wrench.

Background technology

At swivel bolt, when nut and pipe fitting connector, spanner common is at present as fork spanner, double offset ring spanner, combination wrenches, adjustable wrench, hook spanner and box spanner etc., it is all the connector for a certain or several types, and rotate for a kind of fixed dimension or for the connector in certain limit size, they otherwise enter and can operate for the connector of distinctive appearance and size, complex structure, during use, need to carry out regulating according to connector size difference or according to connector profile replacing different from size parts, they use inconvenient, and for being applied to many specifications, complicated to the connecting-piece structure of size, price is higher, and they need to have requirement to connector snap-latch surface, cannot rotational circle tubing connector, for a long time the phenomenon that slide fastener also easily appears in large torsion operation is carried out to connector, it is the front of gland in direction of rotation that monkey wrench common at present normally uses, it bears larger torsion, if movable head is when larger torsion is born in the front of direction of rotation, be easy to cause the damages such as movable head switch out.

Utility model content

In order to make up above deficiency, the utility model provides a kind of monkey wrench, and this monkey wrench structure is simple, and highly versatile is easy to use, cheap.

The utility model in order to the technical scheme solving its technical problem and adopt is: a kind of monkey wrench, comprise handle and gear ring, described handle one end is connected with gear ring is side walls hinged, formation one and the opening portion be communicated with inside gear ring on gear ring circumferential side wall, handle one end can be stretched in gear ring along this opening portion, is equipped with engaging tooth inside described gear ring with handle one end outer surface.

As further improvement of the utility model, described handle one end forms the ramp structure that there is angle with handle side wall, and engaging tooth is positioned at outside this ramp structure.

As further improvement of the utility model, the ramp structure of described handle one end is the outer convex arc surface tilted.

As further improvement of the utility model, the described handle other end is provided with the perforated portion for hanging.

The beneficial effects of the utility model are: the utility model is by gear ring and handle one end fits, inside gear ring and handle one end all arranges engaging tooth, when forward pulls handle, handle one end nature coordinates clamp connection surface with gear ring, engaging tooth tightly can be engaged connector surface, oppositely pull handle, handle one end can be made again to away from connector one sideway swivel, automatically connector is unclamped, so repeatedly just, reverse turn handle just achieves the intermittent in the same way rotation of connector, easy to operate, this spanner part is few, structure is simple, be convenient to processing and manufacturing, production cost is low, cheap, easy to use, do not limit by connector profile and size, even pipe also can stablize rotation, there will not be slide fastener phenomenon, this patent spanner intelligence just can pull revolving part along rotating forward, its reversely rotate time and revolving part release, spanner reversely rotates and does not bear any torsion, can prevent from oppositely pulling revolving part to damage handle and stretch into end in gear ring, avoid occurring that faulty operation damages the phenomenon of spanner.

Detailed description of the invention

Embodiment: a kind of monkey wrench, comprise handle 1 and gear ring 2, described handle 1 one end is connected with gear ring 2 is side walls hinged, formation one and the opening portion 4 be communicated with inside gear ring 2 on gear ring 2 circumferential side wall, handle 1 one end can be stretched in gear ring 2 along this opening portion 4, engaging tooth 3 is equipped with handle 1 one end outer surface inside described gear ring 2, during use, to the connector rotated be needed (as bolt head, nut even pipe etc.) insert in gear ring 2, connector is just positioned at the space of gear ring 2 madial wall and the formation of handle 1 one end lateral wall, forward pulls handle 1, engaging tooth 3 inside gear ring 2 is engaged with connector lateral wall, then now connector clamps towards the rotation of connector direction with gear ring 2 madial wall by handle 1 one end jointly, owing to being all provided with engaging tooth 3 inside handle 1 one end and gear ring 2, connector outer surface is engaged tooth 3 and bites and cannot freely rotate, now pulling handle 1 other end is just with follower link together to rotate, handle 1 is oppositely pulled after certain angle pulled by handle 1, now handle 1 other end departs to rotating in connector outer surface away from connector direction, now connector is released, freely can rotate relative to spanner, forward and oppositely pull handle 1 other end and just achieve connector intermittence rotating Vortex connector so repeatedly, and then realize the locking of connector or unclamp, this structure is simple, without the need to regulating according to connector size during use, also without the need to because any parts of connector profile replacings different from size, the connector of any profile can be suitable for, even if ganoid pipe also can ease rotation, repeatedly to same a connection piece operation, connector also can not slide fastener, easy to use, rotary connector speed is fast, highly versatile, production cost is low, cheap, and revolving part can only be pulled by single direction rotation due to spanner, when it reversely rotates, spanner automatically and revolving part get loose, handle 1 end of stretching out in gear ring 2 can not be subject to excessive torsion, effectively prevent the situation generation that faulty operation damages spanner.

Described handle 1 one end forms the ramp structure that there is angle with handle 1 sidewall, and engaging tooth 3 is positioned at outside this ramp structure, is coordinated with gear ring 2 inner arc face by ramp structure, stablizes piece-holder, is suitable for connector dimensions scope wide.

The ramp structure of described middle handle 1 one end is the outer convex arc surface tilted, when the arc surface of evagination rotates, powerful extruding force is formed to connector surface, when forward pulls handle 1, engaging tooth 3 in outer convex arc surface more firmly can be pulled and more sting clamping joint surface, avoiding slide fastener, can certainly be the interior concaved circular cambered surface tilted.

Described handle 1 other end is provided with the perforated portion 5 for hanging, and convenient wrench is used to complete rear storage and placement.
