After the sampling is completed, start the cylinder again, and the piston rod of the cylinder drives the sampling tube up. During the sampling process, the two support plates can be rotated so that the two support plates are in contact with the ground to support the U-shaped frame. After the sampling is completed, the support plates are rotated and retracted into the rectangular grooves, which enhances the support effect while saving space, thereby avoiding the situation in which the current geological drilling sampling device is usually provided with a large support plate to ensure the stability of the drilling process, resulting in a large space occupation and inconvenience in transportation.

[0016] The effect achieved by the above components is: the rotating ring can be rotated counterclockwise, so that the three adjustment blocks simultaneously push the slide bar to slide inward, clamping and limiting the sampling tube, making the operation more convenient.

[0017] Preferably, a second spring is sleeved on the slide rod, one end of the second spring is fixedly connected to the fixing ring, and the other end of the second spring is fixedly connected to the slide rod.

[0018] The effect achieved by the above components is: when the slide rod clamps the sampling tube, the second spring is in a contracted state, so when the rotating ring is rotated clockwise, the slide rod will slide outward under the action of the rebound force of the second spring, making it easy to remove the sampling tube and further improving the convenience of operation.

[0019] Preferably, a threaded bolt is threadedly inserted on the rotating ring.

[0020] The effect achieved by the above components is: when the position of the rotating ring is adjusted, the threaded bolt can be rotated so that one end of the threaded bolt is tightly against the fixed ring to prevent the rotating ring from rotating during the sampling process.

[0021] Compared with the prior art, the advantages and positive effects of the utility model are that, in the utility model, by setting the support structure, the two support plates can be rotated during the sampling process so that the two support plates are in contact with the ground to support the U-shaped frame. After the sampling is completed, the support plates are rotated and retracted into the rectangular grooves, thereby enhancing the support effect and saving space. The contact area between the support plates and the ground can be increased by sliding the adjustment plates, thereby improving the support effect and making the sampling process more stable. The rubber pad can increase the friction between the adjustment plates and the ground, making the support more stable. When the support plates are retracted, The adjusting plate can be stuck into the slot to prevent the adjusting plate from rotating during transportation. When the adjusting plate slides into the slide slot, the first spring will shrink into the circular groove. At this time, the first spring is in a contracted state, so the support plate is unfolded, and the adjusting plate slides out under the action of the rebound force of the first spring, and when the support plate is folded, the adjusting plate will also be stuck into the slot under the action of the elastic force of the first spring, making the operation more convenient, thereby avoiding the situation that the current geological drilling sampling device is usually provided with a large support plate to ensure the stability of the drilling process, which occupies a large space and is inconvenient for transportation.
