The push block 33 structure pushes the sealing card shell 37 structure in the sealing assembly 36 to engage with the drill rod body 15. The second sealing rubber 40 is arranged to slide between the adjusting rod 41 and the adjusting groove, so that the second sealing rubber 40 and the first sealing rubber 39 are dislocated, so that the drill rod bodies 15 of different sizes can be clamped, thereby achieving a sealing protection effect in the drill rod hole 14, avoiding the drill rod working process, and stones rebounding into the drill rod hole 14, causing damage to the internal working structure of the equipment, thereby improving the service life. After the installation of the drill rod is completed, when it needs to be disassembled and replaced, the above operation principle is the same, and only the control ring 5 needs to be rotated in the opposite direction, and the positioning block 12 is lowered. The limit block 12 descends, bringing the limit bevel down with it, releasing the limit engagement effect with the positioning pin 18.
