Abstract

The utility model provides a high efficiency reciprocating spanner, which is characterized in that a handle whose front end is provided with a main shifting fork and a vice-shifting fork is mutually connected with a fork piece through a shaft; the upper part of the fork piece is provided with a slide slot corresponding to the slide rail of the fork piece; the fork piece is mutually connected with another fork piece through the slide rail. The convex block of the lower part of the fork piece is arranged between the main shifting fork and the vice-shifting fork at the front end of the handle; the middle part of the convex block of the fork piece is processed with a spring groove which is provided with a spring in the interior; the spring is fixed through a pin shaft. The front part of the handle is also processed with a spring groove which is provided with a spring in the interior; the spring is fixed through a pin shaft. The utility model has the advantages of convenient operation, time saving, labor saving, etc.

Description

High efficiency reciprocating spanner

The utility model relates to a kind of wrench, particularly about a kind of prong wrench.

Present wrench mainly contains five kinds: the one, and monkey spanner, it is adjustable that this wrench has specification, widely applicable advantage; The 2nd, the prong wrench, though a kind of specification of this wrench can only be suitable for specifications of nuts of the same race, the tight appropriateness of its interlock is not decreased nut, and is simple to operate; The 3rd, it is better that double off-set spanners, this kind wrench have the characteristics and the intensity of prong wrench; The 4th, impact wrench, this kind wrench specification is supporting, also have one can be reciprocal accessory, can increase work efficiency, reduce labor intensity; The 5th, the Multipurpose templet hand, this wrench promptly can be used for nut and can be used for pipe again, has two kinds of functions of wrench and box spanner.Though above three kinds of wrench of activity, prong, plum blossom respectively have advantage, all have a common drawback, are exactly can not be reciprocal, revolution is moving once will be taken off wrench from the nut that is rotated, insert again again and rotate once, and operation is wasted time and energy; Though impact wrench has reciprocal function, because of the restriction of its structure, there is volume big, unhandy shortcoming, and be not suitable for (construction and installation etc.) or the limited place use of space environment in the high-altitude; And the Multipurpose templet hand has destruction to the nut hex surface because its occlusal surface has teeth during the interlock nut, and the occlusal surface play is excessive when loosening the interlock home position, and inconvenient operation wastes time and energy.

The purpose of this utility model provides a kind of prong wrench that can be reciprocal.

Technical solution of the present utility model is: a kind of high efficiency reciprocating prong wrench, it is characterized in that: front end has main shift fork 1 and is connected with fork part 5 by axle 4 with the handle 3 of paying shift fork 2, fork part 5 tops are provided with and pitch part 6 slide rails 7 corresponding chutes 8, fork part 6 joins by slide rail 7 and fork part 5, the bottom projection 8 of fork part 6 is loaded on the main shift fork 1 of handle 3 front ends and pays between the shift fork 2, fork part 6 projections 8 middle parts are processed with the spring groove 10 that spring 9 is housed in it, spring 9 is fixing by bearing pin 11, handle 3 front portions also are processed with the spring groove 13 that spring 12 is housed in it, and spring 12 is fixing by bearing pin 14.

The utility model is compared with prior art to have: easy to use, and advantage such as processing ease improves work efficiency, and is time saving and energy saving, simple and reasonable.
