Detailed Description

The invention will be further described with reference to the accompanying drawings:

as shown in fig. 1-6, the lengthened handle for valve switch of the present invention comprises an operation sleeve joint 7, a right-angle handle 5 and an oblique-angle handle 1, wherein one end of the right-angle handle 5 is fixedly connected with the operation sleeve joint 7, two sleeves 4 are respectively arranged on two sides of the other end of the right-angle handle 5, the two sleeves 4 are respectively sleeved on two ends of the periphery of a rotating shaft 9 fixed on one end of the oblique-angle handle 1, and a locking nut 2 is respectively arranged on the rotating shaft outside the two sleeves 4, and the locking nut 2 is in threaded fit connection with the rotating shaft 9; the center of the operation sleeve joint 7 is provided with a special-shaped sleeve joint through hole 6.
