Abstract

A combination wrench comprises hoops 1 and a yoke lever 4. Each hoop 1 is composed of two semicircular rings, wherein one ends of the two semicircular rings are hinged through a rotating shaft 7; the two semicircular rings can be opened or closed; when being closed, the two semicircular rings are fastened into a whole through dowels 2. The surface of the inner ring of each hoop 1 is of an inner dodecagon structure. A plurality of circular plug holes 5 are symmetrically ranked around the hoops 1. The yoke lever 4 is of a U shape, the rear end of the yoke lever 4 is fixedly connected with a grip 6, the top end of the yoke lever 4 is fixedly connected with two plug pins 3 which are cones, the diameter of the bottoms of the cones is matched with the diameter of the plug holes 5, the multiple hoops 1 are arranged, and the inner dodecagon structures of the surfaces of the inner rings of the hoops 1 are of multiple specifications to be suitable for screw caps and threaded rods of different specifications. By the utilization of the combination wrench, the screw caps and the threaded rods in a narrow region can be conveniently tightened and demounted.

Description

A kind of combination wrench

Technical field

The utility model relates to a kind of spanner, is mainly a kind of combination wrench that narrow region screw rod is installed.

Background technology

Spanner has developed numerous types now as everyday tools, comprises open-end wrench, monkey wrench, double offset ring spanner and box spanner etc.Wherein, monkey wrench and open-end wrench, because bayonet socket place is thick, are not suitable for using in narrow region, and double offset ring spanner and box spanner are because bayonet socket seals, can only on short nut, use, can not be used on long nut and use, at some special occasions, with upper ejector lever, be all difficult to use.For example, the present hot water pipe of washing nappy, washbowl water pipe bottom of family, mounting distance is narrow and small, and monkey wrench and open-end wrench use inconvenience, and nut is arranged on continuous water pipe, and double offset ring spanner and box spanner cannot use.

Summary of the invention

The purpose of this utility model is to provide a kind of combination wrench, is mainly used in installing narrow region screw rod, nut, to make up the deficiencies in the prior art.

The purpose of this utility model is achieved in that a kind of combination wrench, comprise anchor ear and fork arm, anchor ear is the ring of two semicircles, ring one end of two semicircles is hinged by rotating shaft, ring expansible or the closure of two semicircles, fastening as a whole by pin when closed, the interior ring surface of anchor ear is interior hexagonal or interior 12 corner structures, the periphery symmetry arrangement of anchor ear has a plurality of circular socket holes, it is U-shaped that fork arm is, and fork arm rear end is fixed with handle, and fork arm top is fixed with two plug pins, plug pin is cone, and cone base diameter mates with jack diameter.

As preferably, anchor ear has a plurality of, and the interior hexagonal of the interior ring surface of anchor ear or interior 12 corner structures are of a size of plurality of specifications, to adapt to nut, the screw rod of different size.

As preferably, between anchor ear and fork arm, extension set is also installed, and is the ring of two semicircles, and ring one end of two semicircles is hinged by rotating shaft, ring expansible or the closure of two semicircles, fastening as a whole by extension set pin when closed, extension set periphery has a plurality of circular socket holes of arrangement consistent with anchor ear, and there is the extension set plug pin of a plurality of projections extension set lower surface, extension set is combined with anchor ear by extension set pin, by jack, is combined with the plug pin of fork arm.

By implementing the utility model, can carry out fastening, dismounting easily to the nut in narrow region, screw rod.

Below in conjunction with accompanying drawing, by the specific embodiment, the utility model is described further.

Accompanying drawing explanation

Fig. 1 is top view of the present utility model;

Fig. 2 is front view of the present utility model;

Fig. 3 is the front view of utility model embodiment 2.

In figure, 1 is anchor ear, the 2nd, and pin, the 3rd, plug pin, the 4th, fork arm, the 5th, jack, the 6th, handle, the 7th, rotating shaft, the 8th, extension set, the 9th, extension set pin, the 10th, extension set plug pin.

The specific embodiment

Embodiment 1

A kind of combination wrench, comprise anchor ear 1 and fork arm 4, anchor ear 1 is the ring of two semicircles, ring one end of two semicircles is hinged by rotating shaft 7, ring expansible or the closure of two semicircles, fastening as a whole by pin 2 when closed, the interior ring surface of anchor ear 1 is interior 12 corner structures, the periphery symmetry arrangement of anchor ear 1 has a plurality of circular socket holes 5, fork arm 4 is U-shaped, fork arm 4 rear ends are fixed with handle 6, fork arm 4 tops are fixed with two plug pins 3, plug pin 3 is cone, cone base diameter mates with jack 5 diameters, anchor ear 1 has a plurality of, interior 12 corner structures of the interior ring surface of anchor ear 1 are of a size of plurality of specifications, to adapt to the nut of different size, screw rod.

During use, the anchor ear 1 that selection is mated with nut or screw rod specification, takes off pin 2, open anchor ear 1, anchor ear 1 is enclosed within on nut or screw rod, plug pin 2 and make anchor ear 1 be closure state, the plug pin of fork arm 43 is inserted to jack 5, pull handle 6, the plug pin 3 of fork arm 4 drives anchor ear 1 to rotate by jack 5, thereby drives nut or bolt rotary, when handle 6 is subject to narrow and small region limits and can not be rotated further, extract plug pin 3, again insert applicable jack 5, be rotated further handle 6.

Embodiment 2

A kind of combination wrench, comprise anchor ear 1 and fork arm 4, anchor ear 1 is the ring of two semicircles, ring one end of two semicircles is hinged by rotating shaft 7, ring expansible or the closure of two semicircles, fastening as a whole by pin 2 when closed, the interior ring surface of anchor ear 1 is interior 12 corner structures, the periphery symmetry arrangement of anchor ear 1 has a plurality of circular socket holes 5, fork arm 4 is U-shaped, fork arm 4 rear ends are fixed with handle 6, fork arm 4 tops are fixed with two plug pins 3, plug pin 3 is cone, cone base diameter mates with jack 5 diameters, anchor ear 1 has a plurality of, interior 12 corner structures of the interior ring surface of anchor ear 1 are of a size of plurality of specifications, to adapt to the nut of different size, screw rod, between anchor ear 1 and fork arm 4, extension set 8 is also installed, extension set 8 is the ring of two semicircles, ring one end of two semicircles is hinged by rotating shaft, ring expansible or the closure of two semicircles, fastening as a whole by extension set pin 9 when closed, extension set 8 peripheries have a plurality of circular socket holes of arrangement consistent with anchor ear 1, there is the extension set plug pin 10 of a plurality of projections extension set 8 lower surfaces, extension set 8 is married by extension set pin 10 and anchor ear 1, by plug pin 3 combinations of jack and fork arm 4.
