[0033] Furthermore, the top diameter of the supporting tube wall 6 is larger than the inner diameter of the through hole 17 , so that the bottom plate 4 and the pressing plate 9 are synchronized, thereby preventing the pressing plate 9 from falling off from the upper part of the supporting tube wall 6 .

[0035] Furthermore, the bottom end of the second thread 16 conflicts with the inner bottom of the supporting tube wall 6 , and the top end of the second thread 16 conflicts with the bottom of the positioning plate 8 .

[0036] Furthermore, a limiting groove 18 is provided on the side wall of the through hole 17 and is slidably arranged with the guide block 15 , so as to facilitate the pressing plate 9 to slide down and limit.

[0037] Furthermore, both ends of the pressure plate 9 are provided with a stepping portion 10 for users to step on.

[0038] Furthermore, a level 19 is provided on the upper portion of the pressing plate 9, which can identify whether the pressing plate 9 is pressed down horizontally, thereby facilitating adjustment.

The user drives the sampling drill bit 13 to puncture the sampling soil by driving the handheld motor, and then when the sampling drill bit 13 moves downward, the second thread 16 is continuously squeezed to reduce the impact and damage of the sampling soil on the sampling drill bit 13, thereby protecting the drill bit, and the sampling drill bit 13 is separated from the sampling fixture, which is convenient for carrying and storage.
