Abstract
The invention discloses a switch tool for a straight shank type needle valve. The switch tool comprises a spanner body, a spanner core, a pincer claw, a handle and a rotary knob. The handle of the tool is designed by adopting the fishing rod principle, and when the movement is limited, the opening and the closing of the straight shank type needle valve are realized through shortening the handle; the handle is connected with the spanner body and a seal head through screw threads, so that the dismounting is convenient. The spanner core arranged inside the spanner body achieves the linkage effect, so that the pincer claw can contract and expand, the opening and the closing of the straight shank type needle valves in different specifications are realized, and the pincer claw can be stably clamped on a straight shank. The switch tool has the advantages that the operation is simple, the flexibility is high, the interchangeability is high, in addition, the carrying is convenient, the straight shank type needle valve can be effectively opened and closed, and the problem of labor waste of the straight shank type needle valve is solved.
