A bearing 11 is embedded and installed in the middle of the fixed plate 6, and a sampling rod 9 is fixedly installed on the inner ring of the bearing 11. A movable hole 13 is opened on the bottom plate 2 below the sampling rod 9, and the sampling rod 9 can pass through the movable hole 13 to sample the rock below. A screw hole 18 is opened on the top of the sampling rod 9, and a screw rod 19 is threadedly connected to the inner wall of the screw hole 18. A hand wheel 8 is installed on the top of the screw 19, and the screw rod 19 can be rotated by using the hand wheel 8. A movable plate 17 is installed at the bottom of the screw 19, and a bearing 2 16 is embedded and installed on the fixed plate 6 on one side of the bearing 11, and a connecting rod 14 is fixedly installed on the inner ring of the bearing 2 16.
