In the process of extending and retracting the telescopic shaft of the first cylinder 43, due to the fixing effect of the fixing block 44, the small turntable 42 will be driven, and the small turntable 42 will rotate adaptively, driving the first cylinder 43 to adapt to the angle change, ensuring the stability of the entire horizontal angle adjustment process.

[0038] In a further embodiment, a mounting plate 6 is provided above the front end of the workbench 1, and a second cylinder 71 is symmetrically installed on the top of the mounting plate 6.

A transmission rod 74 is fixedly sleeved inside the gear 73, and an adjustment plate 75 is fixedly sleeved on the outer surface of the middle part of the transmission rod 74.

[0039] In this embodiment, when vertical adjustment is required, the second cylinder 71 is started, and its telescopic shaft drives the rack 72 to move. When the rack 72 moves, it drives the gear 73 to rotate, and the gear 73 drives the transmission rod 74 to rotate. The rotation of the transmission rod 74 will cause the adjustment plate 75 to change the angle in the vertical direction, thereby realizing the vertical adjustment of the device. It can be flexibly adjusted according to different working requirements and environmental conditions to meet the requirements for the vertical angle, thereby enhancing the adaptability and versatility of the device.

While the first telescopic rod 93 moves, it drives the cross shaft 95 to slide on the inner wall of the drill rod 85. The movement of the cross shaft 95 drives the second telescopic rod 97 to move, and the second telescopic rod 97 drives the drill bit 87 to move downward, so that the drill bit 87 and the drill rod 85 are separated from each other, thereby opening the sampling cavity 96, allowing the sample to enter the sampling cavity 96, and achieving the purpose of sampling. This design is simple and convenient to operate, and there is no need to stop the operation for sampling, which realizes the simultaneous drilling and sampling, further improves work efficiency, reduces the time waste caused by work interruption, and reduces the possibility of manual intervention and operational errors.

[0044] In a further embodiment, a telescopic slot 94 is provided at the top end of the drill rod 85 , and a sampling cavity 96 is provided at the bottom end of the drill rod 85 .

[0045] In this embodiment, the telescopic groove 94 can provide space for the first telescopic rod 93 to move inside the drill rod 85, thereby realizing the separation of the drill bit 87 from the drill rod 85.

When the screw rod 53 rotates, the screw sleeve 57 moves up and down on the outer surface of the screw rod 53, and the screw sleeve 57 drives the mounting plate 6 to move up and down. At the same time, the screw sleeve 57 drives the slider 56 to slide synchronously on the fixed rod 52 through the mounting plate 6.
