Description

Quick change ratchet handle

Technical field

The utility model relates to a kind of handle, relates in particular to a kind of quick change ratchet handle.

Background technology

At present the handle of medical industry is all fixed substantially, and interface is fixed, and in actual applications, when, the built-in interface diverse in function that need frequent when commutation, there will be the loaded down with trivial details of replacing instrument, causes waste of time.

Summary of the invention

The technical problems to be solved in the utility model is: at present the handle of medical industry is all fixed substantially, and interface fixes, and can not meet the wrenching bar of any several mouthfuls, and a kind of quick change ratchet handle is provided.

In order to overcome the defect existing in background technology, the utility model solves the technical scheme that its technical problem adopts: a kind of quick change ratchet handle, comprise handle and Handle axis, handle outer is provided with encapsulate assembly, the tail end of described encapsulate assembly is provided with bonnet, described handle and Handle axis are hollow, described handle inside is provided with nut and bearing one, described Handle axis tail end is provided with screw thread, Handle axis tail end is enclosed within on bearing one and with the nut of handle inside and is connected, described handle front end is connected with gear assembly by screw, described gear assembly is connected with Handle axis by bearing two, described gear assembly is provided with spring one, described spring one is provided with hoodle one, described geared parts is connected with camb cap assembly by hoodle one, described camb cap assembly is sleeved in Handle axis, camb cap assembly is provided with draw-in groove, described Handle axis is provided with hoodle two, described Handle axis outside is provided with sliding sleeve, described sliding sleeve is connected with Handle axis with jump ring by spacing back-up ring, described sliding sleeve is provided with spring two.

According to another embodiment of the invention, further comprise that described camb cap assembly is provided with locating ring.

According to another embodiment of the invention, further comprise that described draw-in groove is three.

The beneficial effects of the utility model are: the utility model is saved doctor's rapid-assembling/disassembling screw by changing handle rotation direction, reduce invalid operation, by changing the pattern of built-in interface, coordinate the wrenching bar of any interface, save time and also can meet different clients' needs for operation, and adopt the structural design of hollow, and make cleaning and sterilizing convenient thoroughly, inserting hollow wrench easy to use gram show pin in the situation that.
