Description
Technical Field
The utility model relates to an instrument, in particular to instrument side direction breaks away from mechanism fast.
Background
With the development of modern mechanical and metallurgical technology, hand tools are continuously updated and developed in aspects of modeling design, material use and the like, and design factors such as mechanics, human body functions and the like are fully considered; with the development of social economy and the fine and precise division of industrial production, the manufacture of hand tools is more specialized and the functions are more diversified.
As is well known, many hand tools employ a quick-change structure for facilitating replacement of a socket-type tool head, such as a socket wrench, which is provided with a handle, a connecting rod, and a plurality of socket sets with hexagonal holes or twelve-angled holes, the front end of the tool is generally a regular polygon structure, a steel ball is disposed in a side face of the regular polygon of the structure, an operating cylinder is disposed at the bottom of the steel ball, an inclined plane contacting with the steel ball is disposed on the surface of the operating cylinder, and the steel ball is driven to move in a direction perpendicular to the axis of the operating cylinder by axial movement of the operating cylinder, so as to control the steel ball to be partially embedded into a pit on the inner wall of the socket, thereby achieving.
The structure can be applied to quick-change structures of tools such as a socket wrench and the like, but the structure necessarily requires that the end part of the operating cylinder is exposed out of the main body structure of the tool, and under some special scenes, due to the limitation of structural design, a space capable of accommodating the end part of the operating cylinder to extend out cannot be reserved in the axial direction of the operating cylinder, so that certain limitation still exists in application.
A laterally operated quick release structure has appeared later (for example, patent document 1), and patent document 1: patent grant publication No. CN 205009129U; the device adopts a sliding column which is arranged in a connecting rod and can slide along the axial direction of the sliding column, a positioning surface matched with the steel ball and a quadrilateral chute are manufactured at the outer end of the sliding column, and a spring used for resetting the sliding column is connected at the other outer end of the sliding column; and the bottom of the cylindrical button can contact the inclined plane of the quadrangular chute on the sliding column and can be in sliding pushing fit with the inclined plane.
By pressing the button, the sliding column perpendicular to the pressing direction is driven to move, so that the action of the steel ball is controlled, and quick connection or unlocking is realized. In said technique, there are some drawbacks as follows:
(1) the cylindrical button is reset by the thrust of the spring to the sliding column and the bottom end of the cylindrical button is driven to move outwards by the inclined surface, so that the phenomenon of blocking frequently occurs; meanwhile, the problem that the cylindrical button is easy to separate from the quadrilateral chute of the sliding column to cause falling off exists.
(2) In addition, the stroke of the sliding column depends on the depth of the quadrilateral chute, if the depth is too shallow, the distance between the bulge and the collapse of the steel ball is not enough, so that the problem of unreliable locking of the sleeve or incomplete separation is caused; if the stroke requirement of the sliding column is deeply met, the strength of the sliding column is reduced, the service life of the quick-release structure is greatly shortened, and the size is increased if the size of the sliding column is increased.
