Hold the hand-held frame 1, remove the fixing bolt between the connecting plate 107 and the mounting cylinder 101, and push the connecting plate 107 to make the drill rod 103 slide out from the inside of the mounting cylinder 101. When the drill rod 103 slides out long enough, fix the connecting plate 107 and the mounting cylinder 101 together with the fixing bolt. Then, align the drill rod 103 with the sampling point. The motor 102 works to drive the connecting rod 1021 to rotate. The gear 1022 rotates simultaneously with the connecting rod 1021. The gear 1022 engages with the teeth 1032 to make the drill rod 103 rotate at a high speed, and drill a sampling hole at the sampling point. Then, turn the limit bolt 1041 to make it move down and push the brush plate 104 into contact with the drill rod 103. The staff push the connecting plate 107 towards one side inside the mounting cylinder 101. While the motor 102 drives the drill rod 103 to rotate, the brush plate 104 brushes the passing drill rod 103 to brush off the impurities adhering to the surface of the drill rod 103, realizing the cleaning of the drill rod 103. Then, close the sealing cover 1011. The elastic piece 1012 pops out when it meets the card slot, and closes and fixes the sealing cover 1011 at the opening of the mounting cylinder 101. Store the drill rod 103 inside the mounting cylinder 101 to prevent the staff from accidentally touching the drill rod 103 and causing harm. Then, the staff remove the sealing plug 1061, align the opening of the sample cylinder 106 with the sampling hole. The micro servo motor 1051 drives the lead screw 105 to rotate, so that the sample cylinder 106 enters into the sampling hole. The sample inside the sampling hole is clamped into the sample cylinder 106. Then, take out the sample cylinder 106, plug the sealing plug 1061 at the outlet of the sample cylinder 106 to collect the sample. Finally, remove the sealing plug 1061, take out the sample inside the sample cylinder 106, then push the push rod 1063. The push rod 1063 drives the cleaning rubber ring 1062 to move. The cleaning rubber ring 1062 pushes out the sample adhering to the inner wall of the sample cylinder 106 at the same time until the cleaning rubber ring 1062 completely moves out from the outlet of the sample cylinder 106, and cleans the impurities on the surface of the cleaning rubber ring 1062. Then, release the push rod 1063, and under the action of the spring ring, the push rod 1063 and the cleaning rubber ring 1062 are reset at the same time.

[0035] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
