Detailed Description

The utility model is further illustrated by the following examples in connection with figures 1-3:

the utility model provides a locking connecting fitting of quick installation handle, includes that inside is hollow first connecting piece 1 and the second connecting piece 2 of taking "maintenance window" (first connecting piece and second connecting piece are a shaping, CNC precision machining), first connecting piece 1 is close to the terminal surface of second connecting piece 2 has a screw hole 4, the circumference 10 of second connecting piece 2 be provided with one with the inside "maintenance window" 5 that is linked together of first connecting piece 1 (this mouth is used for overhauling and the effect of installation), second connecting piece 2 is close to the terminal surface of one end of first connecting piece 1 is provided with draw-in groove 6, one side of draw-in groove 6 (this groove is the anticreep draw-in groove) runs through first connecting piece 1 is close to one side terminal surface of second connecting piece 2 extremely between the terminal surface 10 of second connecting piece 5 can reach "quick installation effect", then use the elasticity that the key (the nipple hexagonal spanner) of special configuration is screwed up can, and the pressure of cooperation gasket (the effect of reducing can reach after the resonance and can not become flexible and can reach the locking effect never.

In addition, A, B functions as a connecting handle pull rod, one side of the second groove 6 penetrates through the side wall of one side of the first groove 5, which is close to the second groove 6, a threaded rod 11 is connected in the threaded hole 4 in a threaded manner, one end of the threaded rod 11 is located in the threaded hole 4, the other end penetrates into the second groove 6, and a rotary table 12 is fixedly arranged at one end of the threaded rod 11 penetrating into the second groove.

In this embodiment, the threaded rod 11 is respectively sleeved with a first pad 30, a second pad 31 and a protective sleeve 32, and the protective sleeve 32 is located between the first pad 30 and the second pad 31.

In this embodiment, the area of the first groove 5 is one fourth of the largest longitudinal cross-sectional area of the first connecting handle 1. It can be convenient to extend a short-fitting hexagonal wrench into the second connecting handle 2 to tighten the threaded rod.
