Abstract

The utility model belongs to a multipurpose detachable spanner, which comprises a main piece, a detachable piece, a spring bracket quick adjusting device and an assembling tooth block jaw. The multipurpose detachable spanner is characterized in that a detachable piece rack bar and a rack bar cavity which has the same direction with the main piece are arranged in the main piece, and an adjusting chamber embedded with the spring bracket quick adjusting device is arranged at the position at the lower part of the rack bar cavity which is close to the spanner jaw. The quick adjusting device causes the endless screw to disengage or engage with the rack bar, and the rack bar on the detachable piece has scales and readings. The spanner jaw can be a plane spanner jaw, and can also be a combined spanner jaw. The utility model has the functions of the detachable spanner and the grip wrench, and can also be used as a common measuring tool.

Description

Multipurpose detachable spanner

The utility model belongs to a kind of multipurpose Adjustable wrench in the machine tool field, and it is applicable to enterprise such as industry and to family's cutfit.

Though existing monkey wrench kind is more, owing to structural reason, some difficult problem is still unresolved in the use, and is not firm as folder, easily shortcomings such as slippage and wearing and tearing.

It is a kind of easy to use that the purpose of this utility model is to provide, and both had the monkey wrench function, has the pipe vice function again, also can supply the multipurpose Adjustable wrench of the usefulness of general measure simultaneously.

The utility model is achieved in that the multipurpose Adjustable wrench transfers device and combination block teeth jaw to form by main part, active, spring carrier soon.Main part pulls mouth by the plane and spanner is made one, pulls mouth and becomes the obtuse angle shape with spanner, pulls mouth by the plane for active and makes one with tooth bar, and pull below mouthful end that vertically is positioned at tooth bar on the plane.The top that main part (1) is pulled mouth is provided with active tooth bar (12) and main part (1) rack chamber (3) in the same way, the bottom of active rack chamber (3) is provided with inlays spring carrier and transfers the conditioning chamber of device (4) soon, respectively there is a vertical hole upper and lower of conditioning chamber (4), the top is for placing restrictions on the screwed hole (9) of tooth bar (12) activity thresholds, following for settling the hole of spring (6) and bolt (5), root and rack chamber (3) joint that main part is pulled mouthful (2) are provided with reinforcement (10), muscle (10) is provided with the reseting groove of active reinforcement (11), and two walls of groove are provided with two coordinating holes; Tooth bar (12) is marked with scale (14) and the reading (15) of selecting the folding size, tooth bar (12) back is provided with two not on earth elongated slots (16), pull mouthful (13) for active and be provided with a reinforcement (11) with tooth bar (12) vertical connection place, muscle is established a hole on (11), spring carrier transfers device by worm screw (8) soon, concave cradle (7), spring (6), carriage bolt (5) is formed, respectively there is a breach two upper ends of concave cradle (7), one screwed hole is arranged at the bottom of concave cradle (7), worm screw (8) is loaded in the concave cradle (7), concave cradle is loaded in the main part conditioning chamber (4), the breach fork of two upper ends of carriage is on two sides of tooth bar, and the bolt (5) that has spring (6) is loaded in the middle of concave cradle (7) bottom outside; The back side of two block teeth of combination block teeth jaw is flute profile or plane, the front flank of tooth is designed to difform tooth face according to different purposes, one convex is arranged and be provided with a screwed hole with block teeth (17) root of main part (1) combination, be coordination double end convex and be provided with two coordination screwed holes with the root of block teeth (18) of active (19) combination, block teeth also can and main part (1), active (19) make one separately.

The utility model good effect is the integrated application that adjustable wrench and the two technology of pipe vice combine, and has one's own knack on the structure technology, not only is different from adjustable wrench but also be different from pipe vice, and its function mainly shows as three aspects.One has the adjustable wrench function, and chucking power is tight, and higher clamping effect is arranged, and clamping is solid and reliable.Two have and the identical function of pipe vice.Three have the effect of general measure.Advantage of the present utility model is that folding size plasticity is big between two mouthfuls of wrench, has avoided the active mouthful of narrow deficiency of folding degree fully.And designed fast accent device, improved folding speed effectively; This wrench has also designed scale and reading, can further improve the speed of fast accent and help to improve the accuracy of folding.

Below in conjunction with accompanying drawing the utility model is explained in detail:
