[0021] Please refer to the attached Figure 1-2 A telescopic valve gate key comprises a key body 1, a fixed cylinder 2 is connected and fixed on the upper surface of the key body 1, a cylinder 4 is inserted in the fixed cylinder 2, a spiral groove is provided on the annular surface of the fixed cylinder 2, and a plurality of slots 3 arranged at equal intervals are provided in the spiral groove, a plurality of rectangular grooves are provided on the annular surface of the cylinder 4, a plug plate 12 is inserted in the rectangular groove, one end of the plug plate 12 away from the rectangular groove is plugged in the slot 3, one end of the rectangular plate in the slot 3 is connected and fixed with a first elastic member 11, the first elastic member 11 is a spring, the first elastic member 11 is in a normal state, one end of the first elastic member 11 away from the plug plate 12 is connected and fixed with a slide plate 10, and the slide plate 10 is slidably connected in the rectangular groove.

[0022] A threaded hole connected to the rectangular groove is provided on the upper surface of the cylinder 4, and a screw 6 is connected to the inner thread of the threaded hole. One end of the screw 6 away from the threaded hole extends to the outside of the fixed cylinder 2. An outer cylinder 5 is connected and fixed to the upper surface of the cylinder 4 to facilitate the rotation of the cylinder 4. A through hole connected to the threaded hole is provided on the surface of the outer cylinder 5, and the screw 6 is inserted into the through hole.

[0023] A second elastic member 9 is connected and fixed on the upper side of a side of the slide plate 10 away from the first elastic member 11. The second elastic member 9 is a spring and is in a stretched state. An end of the second elastic member 9 away from the slide plate 10 is connected and fixed to a fixed plate 8. The fixed plate 8 is connected and fixed in a rectangular groove. An arc plate 15 is connected and fixed on the lower side of a side of the slide plate 10 away from the first elastic member 11. The arc plate 15 is in sliding contact with the screw 6.

[0024] A plurality of blocking structures consisting of an insert plate 12, a first elastic member 11, a slide plate 10, a second elastic member 9, a fixed plate 8 and an arc plate 15 are installed in the rectangular groove. The blocking structure is used to limit the position of the cylinder 4 in the fixed cylinder 2, so that the length of the outer cylinder 5 outside the fixed cylinder 2 changes, thereby changing the length of the valve gate key. The screw 6 is used to limit the position of the blocking structure in the rectangular groove. By removing the screw 6, the length of the outer cylinder 5 outside the fixed cylinder 2 can be shortened, thereby making it more convenient to change the length of the valve gate key.

[0025] In order to facilitate the removal of the plug board 12 from the slot 3, a first inclined surface 13 is provided on one side of the plug board 12, and the first inclined surface 13 contacts the rectangular groove. A second inclined surface 14 is provided on the side of the plug board 12 away from the first inclined surface 13, and a certain distance is left between the second inclined surface 14 and the rectangular groove.

[0026] In order to facilitate the rotation of the outer cylinder 5 , a fixed rotating handle 7 is connected to the annular surface of the outer cylinder 5 on the side away from the cylinder 4 .

[0027] The specific operation process of the utility model is as follows: when the length of the fixed cylinder 2 and the outer cylinder 5 needs to be increased, the outer cylinder 5 only needs to be rotated clockwise. Since the first inclined surface 13 is in contact with the rectangular groove, when the outer cylinder 5 rotates, the plug plate 12 squeezes the first elastic member 11 and moves into the rectangular groove, so that the cylinder 4 can rotate in the fixed cylinder 2.

[0028] When the length of the fixed tube 2 and the outer tube 5 needs to be shortened, the screw 6 is taken out from the threaded hole. At this time, the arc plate 15 loses the obstruction of the screw 6, so that the second elastic member 9 contracts, the insert plate 12 is pulled into the rectangular groove, and the second inclined surface 14 contacts the rectangular groove. Then the outer tube 5 is rotated counterclockwise, and the length of the fixed tube 2 and the outer tube 5 is shortened.

[0029] When the valve needs to be opened, the screw rod 6 is threadedly connected in the threaded hole so that the second inclined surface 14 does not contact the rectangular groove. At this time, the key body 1 is rotated counterclockwise to open the valve.

[0030] The above description of the utility model in combination with the accompanying drawings is an exemplary description. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as the non-substantial improvements are made by adopting the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
