[0027] The use method and advantages of the present invention: The sampling device for quality engineering detection has the following working process: like Figures 1 to 6As shown: first, the device is placed at the desired location. The battery pack 4 converts DC power into AC power for the entire device under the action of the inverter. The electric telescopic column 2 is extended to drive the support box 3, the mobile frame 503, the first sleeve 504 and the sampling drill bit 508 to move up and down, which is convenient for positioning the sampling drill bit 508. The sampling drill bit 508 is fixed to the first sleeve 504 by a nut 509. The sampling drill bit 508 can be removed and replaced. After the positioning operation is completed, the first shaft 517 rotates, and the first sleeve 5 04 rotates under the driving action of the driving pulley 506, the belt 507 and the driven pulley 505, thereby driving the sampling drill bit 508 to rotate. At the same time, the second rotating shaft 520 rotates under the driving action of the first bevel gear 518 and the second bevel gear 519, thereby driving the extrusion wheel 521 and the second sleeve 522 to rotate, the square column 524, the cylinder 525 and the third sleeve 526 to rotate, and the screw rod 527 rotates to drive the second piston 529 to move downward. Hydraulic oil is stored in the first oil cylinder 528, and the third piston 534 is driven by the oil pressure. The movable frame 503 slides to the right under the action of the extrusion wheel 521, and the movable frame 503 slides to the right. The sampling drill bit 508 rotates and moves to the right at the same time. The sampling drill bit 508 drills into the wall to take samples. Water is stored in the water tank 510. When the extrusion wheel 521 rotates, the movable rod 514 and the first piston 5122 move back and forth left and right under the extrusion of the extrusion wheel 521 and the supporting action of the second compression spring 515. When the first piston 5122 moves to the right, the opening and closing member 5123 is automatically closed. When the first piston 5122 moves to the left, the opening and closing member 5123 is automatically opened. The piston 5122 repeatedly presses water to the right, thereby automatically pumping the water in the water tank 510 into the first connecting pipe 5124 and the water spray pipe 513 and spraying it out, thereby cooling the sampling drill bit 508. After completing the sampling operation, the lifting rod 530 is held and the square column 524, the cylinder 525 and the third sleeve 526 are lifted upward to make the third sleeve 526 leave the screw rod 527. The movable frame 503 is automatically reset under the action of the first compression spring 502, and the sampling drill bit 508 is automatically reset and pulled out of the wall.
