Detailed Description

In order to make the objects, technical solutions and advantageous effects of the present utility model more apparent, preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate understanding of the skilled person.

As shown in fig. 1-3, the hand wheel valve opening and closing assisting tool comprises a handle 1, two spanner heads 2 and two screws. The handle 1 is a telescopic rod, in particular a sleeve structure, and is formed by connecting two sleeves. The handle 1 is provided with screw holes 6, screw holes 6 are arranged at the lower ends of the two sleeves, the screw holes 6 at the lower ends of the sleeves are overlapped after the handle 1 is stretched, and the handle 1 can be extended for use by inserting screws into the screw holes 6. Screw holes 6 are formed in the upper ends of the two sleeves, screws are inserted in the two sleeves during shrinkage, storage can be facilitated, and the length of the handle 1 can be adjusted according to field use.
