[0035] The working principle and use process of the present application are as follows: According to the depth of the sample, the position of the pushing plug 3 in the sampling drill cylinder 1 is adjusted, that is, the rotating limiting sliding groove 7 is moved up and down along the outer surface of the sampling drill cylinder 1 under the cooperation of the adjusting screw 5, and then the adjusting plug 2 is moved up and down along the inside of the sampling drill cylinder 1 under the cooperation of the limiting sliding groove 7 and the connecting slide block 8, and then the pushing plug 3 is moved up and down by the buffer spring 4; Due to the movement of the pushing plug 3, the locking ring 111 can be moved up and down by the connecting slide block 8 connected thereto, and then the fixed sleeve rod 121 and the connecting slide rod 122 connected by the sealing sleeve can be extended and retracted under the cooperation of the sealing pad 113 and the gas hole at the top thereof; after the adjustment, the locking ring 111 is rotated to slowly move the sealing pad 113 downward under the cooperation of the communication ring 112, and finally the sealing pad 113 is sealingly attached to the gas hole at the top of the communication ring 112 to prevent the flow of airflow, so as to fix the length of the fixed sleeve rod 121 and the connecting slide rod 122 as a whole; Then the top of the sampling drill cylinder 1 is connected with the motor output shaft, the motor is started to drive the sampling drill cylinder 1 to rotate, the sampling drill cylinder 1 is continuously drilled downward by the drill teeth 103, and the soil and stone in the middle part can be extruded to increase the compactness and be rotated into the inside of the sampling drill cylinder 1 under the cooperation of the sampling tightening guide cavity 13, until the bottom of the pushing plug 3. When the middle soil contacts the bottom of the resistance block 32 during drilling, the pushing plug 3 can avoid friction with the soil under the cooperation of the rotating clamping ring 33; and with the continuous drilling, the soil continuously rises relatively due to the continuous descent of the sampling drill cylinder 1, and finally pushes the pushing plug 3 to rise, that is, the locking component 11 is driven to rise through the corresponding connecting slider 8, and then the drill bit connecting seat 102 is driven to rise through the connecting component 12 and the dismounting connecting ring 104, and then the drill bit 103 is retracted into the inside of the fixed head 101, so that the drilling is stopped.
