The structure has the advantages that the handle component adopts a modular structure design, thereby facilitating the modular assembly of the handle component and the operating lever and having higher assembly efficiency; the connecting sleeve is clamped with the operating lever through the split washer, so that the connecting sleeve and the operating lever can be assembled conveniently, the auxiliary contact screw can flexibly trigger the bottom auxiliary contact, the reset impact on the bottom contact support in all directions can be effectively relaxed, and the operating handle is favorable for improving the working reliability. Therefore, the master controller control handle has the advantages of simple structure, stable and reliable performance, convenience and quickness in assembly, long service life and good operation hand feeling.
In particular, one end of the auxiliary contact screw is provided with a trigger part which is exposed outside the operating rod and is matched with the auxiliary contact, and the trigger part is in a conical shape. The design of the triggering part of the auxiliary contact screw is in a cone shape, the triggering part of the structural design can flexibly trigger the auxiliary contact at the bottom, and can effectively smooth the reset impact on the bottom contact support in all directions, thereby being beneficial to improving the working reliability of the control handle.
Particularly, the other end of the auxiliary contact screw is provided with a clamping part matched with the operating rod, the operating rod is provided with a clamping hole matched with the clamping part, and the clamping part is clamped in the clamping groove and forms clamping matching of the auxiliary contact screw and the operating rod. The auxiliary contact screw is connected with the operating rod in a clamping fit mode, so that the auxiliary contact screw and the operating rod are convenient to assemble, and the assembly efficiency of the operating handle is improved.
Particularly, a plurality of reinforcing convex ribs are arranged in the handball corresponding to the outer peripheral wall of the sleeve. The reinforced convex ribs can enhance the strength of the sleeve and are beneficial to prolonging the service life of the handball.
Particularly, the upper end of the handball is provided with an inclined plane, and two sides of the handball are respectively provided with a plane. The handball is provided with the inclined plane and the plane respectively, so that the operation hand feeling can be enhanced, and the fatigue of hands is not easy to generate.
