[0030] Reference Figure 1-7 The utility model provides an embodiment: a portable soil sampling device, including a fixed tube 1, a pressure tube 2 and a connecting tube 20, a movable block 4 is fixedly provided at the lower end of the connecting tube 20, and four grooves 17 are opened at the lower end of the movable block 4, and the four grooves 17 are hingedly provided with digging clamps 3 inside, and the hinges of the four digging clamps 3 and the four grooves 17 are provided with torsion springs 18.

[0031] By setting the movable block 4, the four digging clamps 3 can be driven to move downward. By setting the digging clamps 3 and setting the bottom of the digging clamps 3 to an inclined surface, it can be easily inserted into the soil. By setting the torsion spring 18, the four digging clamps 3 can be driven to gather and dig and clamp the soil. By setting the push plate 5, the four digging clamps 3 can be supported so that the four digging clamps 3 are opened. When sampling, the soil pushes the push plate 5 upward so that the push plate 5 no longer supports the digging clamps 3, so that the digging clamps 3 are gathered.

[0032] Slide grooves 10 are provided on both sides of the pressure tube 2, and a connecting plate 7 is movably sleeved inside the pressure tube 2. Sliders 8 are fixedly provided on both sides of the connecting plate 7. The two slides 8 respectively pass through the two slide grooves 10 and are fixedly provided with a ring 9 at the opposite end. A push rod 6 is fixedly provided at the lower end of the connecting plate 7, and a push plate 5 is fixedly provided at the lower end of the push rod 6. A through groove 14 is provided at the upper end of the fixed cylinder 1, and a block 19 is fixedly provided at the lower front end of the pressure tube 2.

[0033] By setting a connecting plate 7 to connect the ring 9 and the push rod 6, the push rod 6 can be moved downward by sliding the ring 9 to push the push plate 5 to push out the soil, or the push plate 5 can be pushed downward to press the four digging clamps 3 to open. By setting a through groove 14 and a clamping block 19, the pressing pipe 2 can press the movable block 4 downward to make the digging clamps 3 leak out.

[0034] A ring plate 15 is fixedly provided at the lower part of the fixed cylinder 1, and a fixing nail 16 is fixedly provided at the lower end of the ring plate 15. By arranging the ring plate 15 and the fixing nail 16, the equipment is more stable when placed on the ground for sampling. A return spring 13 is fixedly provided at the upper end of the movable block 4. The upper end of the return spring 13 is fixedly connected to the inner top surface of the fixed cylinder 1. By arranging the return spring 13, the movable block 4 can be pulled upward by the tension of the return spring 13. A clamping ring 21 is fixedly provided at the upper end of the connecting pipe 20, and a ring groove 22 is provided at the lower end of the pressure pipe 2. The clamping ring 21 and the ring groove 22 are movably sleeved. By arranging the clamping ring 21 and the ring groove 22 movably sleeved, the connecting pipe 20 can be connected to the pressure pipe 2 at the same time. The pressing tube 2 can be rotated independently, so that the blocking block 19 can be turned to one side to prevent the pressing tube 2 from moving downward. A top plate 11 is fixedly provided on the upper end of the pressing tube 2, and a handle 12 is fixedly provided on the upper end of the top plate 11. The top plate 11 is provided to facilitate pressing the pressing tube 2, and the handle 12 is provided to facilitate lifting the equipment. The push rod 6 passes through the movable block 4 and is movably sleeved with the movable block 4. The push rod 6 can be movably sleeved with the movable block 4 by the push rod 6 and the movable block 4. The push rod 6 can be moved downward in the movable block 4. The connecting tube 20 passes through the inside of the fixed tube 1, and the connecting tube 20 is movably sleeved with the return spring 13. By passing the connecting tube 20 through the inside of the fixed tube 1, the connecting tube 20 can be pressed down on the movable block 4 by pressing the pressing tube 2.

[0035] Working principle: The device is provided with a fixed cylinder 1, and a digging clamp 3 is provided inside the fixed cylinder 1. When taking soil samples, after placing the device on the ground, the digging clamp 3 is pressed by pressing the pressure tube 2 to enter the soil. At the same time, the soil will push the push plate 5 after entering the fixed cylinder. After the push plate 5 reaches the uppermost end of the fixed cylinder 1, multiple digging clamps 3 gather inward under the action of the torsion spring 18 to dig and clamp the soil, and then move the pressure tube 2 upward to allow the collected soil to enter the fixed cylinder 1. Then, by sliding the ring 9 downward, the push rod 6 pushes the push plate 5 to push the soil out of the fixed cylinder 1 into the container for collecting the soil. After use, the pressure tube 2 can be rotated so that the block 19 is not aligned with the through groove 14 to avoid accidentally pressing down the pressure tube 2 so that the digging clamp 3 leaks out of the fixed cylinder 1 and accidentally injures people or damages the digging clamp 3.
