A strip-shaped plate 206 is rotationally connected to the end of the pull rod 204 penetrating the partition plate 203. A spring 205 is sleeved outside the pull rod 204, one end of the spring 205 abuts against the support disc 201, and the other end of the spring 205 abuts against the partition plate 203. Two support plates 207 are fixed to the bottom of the partition plate 203, and the distance between the two support plates 207 is less than the length of the strip-shaped plate 206. The partition plate 203 divides the circular groove 202 into an upper chamber and a lower chamber. The support disc 201 and the spring 205 are located in the upper chamber, and the strip-shaped plate 206 and the support plates 207 are located in the lower chamber.

[0025] In use, the strip-shaped plate 206 is first pulled downward to drive the support disc 201 to move downward and compress the spring 205. Then, the strip-shaped plate 206 is rotated by ninety degrees so that the line between the two support plates 207 is perpendicular to the strip-shaped plate 206 (it should be noted that the line between the two support plates 207 is parallel to the strip-shaped plate 206 initially). Then, the strip-shaped plate 206 is released. At this time, the support plates 207 prevent the strip-shaped plate 206 from moving upward, i.e., the position of the support disc 201 is fixed. Then, the test tube 103 containing soil is placed into the test tube groove 102.

[0026] Further, the column body 101 is fixed with a vertical plate 106, one side of the vertical plate 106 is fixed with a cylinder body 107, the cylinder body 107 is slidably connected with a cylindrical rod 108, the bottom of the cylindrical rod 108 is fixed with two limiting blocks 109, two stroke grooves 115 are formed in the cylinder body 107, the two limiting blocks 109 are slidably fitted in the corresponding stroke grooves 115 respectively, the column body 101 is fixed with a connecting plate two 113, one end of the connecting plate two 113 away from the column body 101 is fixed with the cylinder body 107, a screw hole 114 is formed in the connecting plate two 113, the top of the cylindrical rod 108 is rotatably connected with a rotating disc 110, the rotating disc 110 is fixed with a connecting plate one 111, one side of the connecting plate one 111 away from the rotating disc 110 is fixed with the cover plate 104, the connecting plate one 111 is threadedly connected with a screw rod 112, the screw rod 112 is threadedly connected with the screw hole 114.

[0027] In use, when the test tube 103 containing soil is placed in the test tube groove 102, the cover plate 104 is rotated to drive the rotating disc 110 to rotate on the top of the cylindrical rod 108, the cover plate 104 is rotated to the top of the column body 101, then the cover plate 104 is moved downward so that the plug block 105 is embedded in the test tube groove 102, then the screw rod 112 is rotated to be threadedly connected with the screw hole 114, that is, the cover plate 104 is fixed, at this time the plug block 105 blocks the test tube groove 102, then the strip-shaped plate 206 is rotated by ninety degrees so that the supporting plate 207 no longer blocks the strip-shaped plate 206, at this time the supporting disc 201 is driven to move upward under the elastic force of the spring 205, so that the top of the test tube 103 abuts against the plug block 105, that is, the test tube is blocked.

[0028] The mounting mode, connecting mode or setting mode disclosed in the embodiment are all common mechanical connecting modes, as long as the beneficial effects can be achieved, and the electrical components in the embodiment are electrically connected with the master controller and the power supply, the master controller can be a conventional known device such as a computer which plays a control role, the skilled in the art can realize the control of the electrical components through simple programming, and the existing disclosed power connection technology also belongs to the common knowledge in the art, so the specific structure composition and working principle are not described in detail.
