Abstract
The improved fixing structure of ratchet wrench spring for attaining the goal of overcoming separation of spring and raising working efficiency mainly comprises two main portions of spring and spring fixing pin. The spring is made up by coiling steel wire and can be used for applying stretching force, its two end feet are the fulcrums of said spring, the spring fixing pin is made into the form of cylinder body whose surface has screen threads or rough-plane to ofrm leakproof fit with spring fixing pin hole. The spring is positioned in the strip rabbet of ratchet wrench, its one end is entered into insert strip slot portion of hook-shaped jaw, and its other end is wound round the spring fixing pin cross-passed through strip rabbet wall. Said invention not only can retain the function of original structure, which utilizes stretching force of spring to make hook-shaped jaw quickly restore, but also can overcome the separation of spring by using said improved structure so as to raise working efficiency.
Description
The present invention relates to a kind of hand tools that is used for, especially for the spring-fixed structure of pawl wrench class hand tools.
Generally be used to promote and keep ratchet class spanner to collude shape to pull the structure that mouth resets be a kind of spring reset structure, the both ends of the spring pin of this structure anchors on the cinclides of pulling in the body strip notch as the fulcrum in force and spanner colludes shape and pulls and mouthful insert on the inner eyelet that divides of strip notch.Thus, the tension force of spring produces and a kind ofly spanner to be colluded shape pulls the strength that mouth upwards pushes away, and makes when the operation spanner collude shape to pull mouth and reset and remain on purpose on original fixed position to reach spanner.In real the work, spanner is whenever pulled and is just meaned that once spanner colludes shape and pulls that mouth will once reset and spring will be subjected to once pushing, so, and this reset and the action that is squeezed will repeat continually.Because spanner handle body strip notched wall is thin, making spring leg as fulcrum insert this strip notch cinclides degree of depth is restricted, the phenomenon that fulcrum of spring landing from the strip notch cinclides in use can usually occur, thereby brought great inconvenience to the operator, influenced operating efficiency.Though Chinese patent 93218174.0 and 98244196.7 has function preferably, use also more conveniently, there is certain defective in its spring structure, and in use spring is usually because of above-mentioned former thereby the phenomenon of landing occurs, thereby influences operating efficiency.
The objective of the invention is to provide a kind of spring-fixed structure of improved ratchet class spanner, make it can be effectively used to and to adopt in the similar hand tools of spring-fixed structure, overcome the purpose that spring comes off and increases work efficiency to reach.
The object of the present invention is achieved like this:
This spring-fixed structure mainly is made of spring and two major parts of spring steady pin: spring is formed by the steel wire coiling, implement tension force, its two ends foot be this fulcrum of spring, and a fulcrum is fixed in and colludes shape and pull on mouthful insertion strip notch one position, and another fulcrum is wrapped on the spring steady pin; The spring steady pin is a cylindrical shape, and its surface has screw thread or matsurface.The spring steady pin crosses spanner top strip notch, as the anchor point of spring one fulcrum, spring one fulcrum is twined on it securely, and spring steady pin thread surface or matsurface and spring pin hole form and closely cooperate.
The present invention has not only preserved and has utilized spring tension to make it collude shape on the above-mentioned patent original structure to pull mouthful a function that resets rapidly when operation, and adopted spring one end pin has been wrapped in method on the spring pin that crosses the strip notched wall, overcome in the above-mentioned patent because spanner strip notch cinclides is thin, and put the phenomenon that is easy to slippage in thin-walled upper spring fulcrum, fundamentally solve this problem, thereby improved operating efficiency.
The present invention only relates to two parts of ratchet class spanner, thus simple in structure, also be convenient to make.
Concrete structure of the present invention is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the spring front elevation 1-1 of the spring-fixed structure of a kind of hand tools of proposition according to the present invention, spring steady pin side Fig. 1-2 and structure chart 1-3.
Describe the concrete spring-fixed structure details that proposes according to the present invention in detail below in conjunction with Fig. 1:
A kind of hand tools that is used for is especially for the spring-fixed structure of pawl wrench class hand tools.This spring structure comprises spring (1) and (2) two major parts of spring steady pin, its characteristics are that spring is formed by the steel wire coiling, its leg (3) end is the little hook in a right angle, hooks to pull a mouthful insertion strip slot notch portion front portion (4), and another leg (5) is a round; Pass from the round leg when spring steady pin crosses handle body cylindrical void, the round leg is twined on its spring steady pin (6).
