Abstract

The utility model relates to a quick multi-function wrench which is a new structural product in the technical field of hardware tools for daily use in light industries. The utility model is a hand tool used for production, assembly and maintenance of nearly all industries such as machinery, light industries, metallurgy, construction, petrifaction, etc. and is also an ideal necessary tool for households. The utility model is formed by combining a fixed hand lever, a movable hook head, a straight pin, a spring, etc., wherein, the front end surface of the hand lever forms a working jaw together with the inner edge of the hook head. The utility model has the advantages of simple structure, rapid actions, flexibility and reliability, and the utility model can completely replace a traditional and city-sold hand grip wrench and an adjustable spanner and can also be made into serial products.

Description

The quick multifunctional spanner

A kind of quick multifunctional spanner, relate to light industry haberdashery and hardware field of tool, it be machinery, light industry, metallurgy, building, petrochemical industry almost be assembling such as the machinery, device, member, equipment of the whole industry, produce, the manual tool of maintenance, also be the ideal tools of family's indispensability.When using with pipe vice, monkey wrench, to regulate out apart from so that adapt to the workpiece of many descriptions in traditional, commercially available hand by worm gear, worm screw, present technique is more bothersome relatively, occur sometimes skidding or stuck phenomenon, make adjustment malfunctioning, the present invention's purpose is, can overcome above-mentioned shortcoming, the quick multifunctional spanner that can substitute pipe vice and normal activity spanner fully is provided.Have fast, advantage, and reliable in action flexibly, easy to maintenance, its shortcoming is indentation may occur on its surface pulling nut, bolt, pipe etc.

It has a fixing handle 1. with the rotating gib head of likeness in form people's ear or a question mark 4., the inner edge working face is processed into straight tooth gullet plate and anti-tooth gullet plate respectively on its front end inclined working and the gib head, form a work jaw, gib head 4. bottom inserts in the body cavity of handle shirtfront, 3. locate by straight pin, with hand propelled gib head lower end, handle 1. and the spring of gib head between 4. 2. be subjected to pulling force, make gib head head rotation 4. open (can reach 90 °) and enter station, unclamping the back makes working hole bite workpiece by spring force, pull handle and 1. get final product work, pushing away the gib head end again with hand opens jaw, withdraw from station, 2. the rear spring of loosing one's grip makes gib head 4. reset, and finishes the spanner function.

Accompanying drawing is the front view of quick multifunctional spanner.

An optimum implementation is seen accompanying drawing, practice and dotted line are respectively quiet, the moving states of this spanner in the accompanying drawing, scratch on the handle front end 1., on inclined working, be processed into the less straight-tooth gullet plate of pitch (title lower jaw), chest has groove, the angle of gullet plate and handle axis is about 30 °, with the angle of baseplane be about 56 °.Gib head head 4. is circular, two of its inner rim are with 120 ° of crossing working faces, intersect with 23 ° and 37 ° of angles respectively with the outside diameter line, it is processed into the bigger anti-tooth gullet plate that colludes inwards of pitch, play ratchet (deserving to be called jaw), gib head afterbody 4. is flat, and it is 1. 3. fixedly connected with straight pin in the chest body groove to insert handle, spring 2. fixedly gib head 4. afterbody and handle hollow notch 1. in a side, on, lower jaw forms jaw, with the tail end of hand push gib head, make gib head 4. can 3. rotate 90 °, i.e. opening around bearing pin, change to adapt to workpiece size, armrest thrust and spring tension make the energy clamping of this spanner and unclamp workpiece, after promptly 4. gib head opens with hand push, workpiece are contained into jaw, by spring pulling force 2. jaw is closed after openhanded and bite workpiece, can pull the handle acting immediately, hand pushes away gib head tail end 4. again opens gib head, withdraws from station, openhanded, 2. resetted by spring, this example can be made into series of products, as long as change related parameter is arranged.
