The guide cone 2 is clamped on the left side of the barrel 1, the barrel 1 and the guide cone 2 are interconnected, three outer support plates 3 are slidably connected to the guide cone 2, the outer support plates 3 are connected to the guide cone 2 with internal springs 30, a blocking pad 4 is connected to the outer side of the left part of the guide cone 2, and three limiting plates 5 are clamped on the barrel 1.

[0021] like Figure 1-Figure 4 As shown, it also includes a tail rod 6, a screw rod 7 and an end rod 70. The tail rod 6 is connected to the right side of the barrel 1, the screw rod 7 is rotatably connected to the right side of the tail rod 6, and the end rod 70 is connected to the right side of the screw 7. An inflation tube is provided on the end rod 70, and the end of the inflation tube is connected to the barrel 1 to facilitate inflation of the blocking pad 4.

[0022] like Figure 1 and Figure 3 As shown, it also includes a clamping ring 8, spring steel 9, a cushion 10 and a cover plate 11. The clamping ring 8 is threadedly connected to the screw rod 7, twelve spring steels 9 are connected to the outside of the tail rod 6, cushions 10 are connected between the left sides of the spring steels 9, and the cushion 10 is connected to the cover plate 11. The spring steels 9 are all connected to the cover plate 11.

[0023] like Figure 1 and Figure 3 As shown, it also includes a fixing frame 12, an angle adjustment arm 13 and a fixing cone 14. The screw rod 7 is rotatably connected to the fixing frame 12. Three angle adjustment arms 13 are rotatably connected to the fixing frame 12. The angle adjustment arms 13 are all threadedly connected to the fixing cone 14.

[0024] like Figure 1 and Figure 4 As shown, it also includes a movable seat 15, an adjusting screw rod 16 and a support frame 17. The movable seat 15 is located below the end rod 70. The upper rear side of the movable seat 15 is rotatably connected to the adjusting screw rod 16. The adjusting screw rod 16 is threadedly connected to the support frame 17. The support frame 17 is slidably connected to the movable seat 15, and the support frame 17 is rotatably connected to the end rod 70.

[0025] When using the utility model, first move the movable seat 15 to the coal mine gas extraction hole, then rotate the adjusting screw 16 according to the height of the extraction hole, adjust the height of the support frame 17, and then adjust the height of the end rod 70 to make the guide cone 2 flush with the extraction hole, then push the movable seat 15 close to the extraction hole, so that the barrel 1 moves to push the guide cone 2 into the extraction hole, and through the action of the internal spring 30, the outer support plate 3 contacts the inner wall of the extraction hole, so that the guide cone 2 can be stabilized in the extraction hole, and then fill the gas into the inflation tube to expand the sealing pad 4 to seal the extraction hole, and then remove the guide cone 2 from the barrel 1 to facilitate subsequent sealing operations. When the guide cone 2 enters the extraction hole, the limiting plate 5 can be fixed to the corresponding position of the barrel 1 according to the depth of the extraction hole to limit the length of the barrel 1 entering the extraction hole. , and then control the depth of the guide cone 2 entering the extraction hole, thereby controlling the depth of the extraction hole sealing and ensuring the effective sealing of the extraction hole.
