[0027] The bottom of the gripping block 100 is provided with an adjustment assembly 700, which includes a fixed rod 701. The bottom of the gripping rod 300 is rotatably connected to a rotating shaft 702. The adjustment rod 703 is manually rotated, so that the adjustment rod 703 drives the rotating shaft 702 fixedly connected thereto to rotate. The bottom of the rotating shaft 702 is fixedly connected to the adjustment rod 703, the side of the rotating shaft 702 is fixedly connected to the gear 704, the side of the fixed rod 701 is fixedly connected to the hydraulic chamber 1 705, one end of the hydraulic chamber 1 705 is slidably connected to a gear rod 706, the gear rod 706 is located at the side of the gear 704, and the gear rod 706 is in a meshing state with the gear 704. When the rotating shaft 702 rotates, the rotating shaft 702 immediately drives the gear 704 fixedly connected thereto to rotate, so that the gear 704 drives the gear rod 706 meshed therewith to move downward, and cooperates with the hydraulic chamber 1 705 slidably connected to the gear rod 706, so that the pressure in the hydraulic chamber 1 705 increases. The other end of the hydraulic chamber 1 705 is slidably connected with a limiting rod 707, and a through slot 708 is provided on the side of the telescopic rod 500. The through slot 708 is located at the side of the limiting rod 707, and the cross-sectional shape of the through slot 708 is the same as the cross-sectional shape of the limiting rod 707. When the pressure in the hydraulic chamber 1 705 increases, the limiting rod 707 slidably connected to the hydraulic chamber 1 705 is driven to move, so that the limiting rod 707 passes through the through slot 708 and is stuck in the interior of the telescopic rod 500, so that the telescopic rod 500 cannot be retracted. At this time, after the piercing rod 600 is inserted into the ground by manipulating the gripping block 100, the telescopic rod 500 will always be in a long state, reducing the possibility of insufficient distance caused by the telescopic bottom of the device in this case, making the device easier to use.

[0028] When in use, the adjusting rod 703 is manually rotated, so that the adjusting rod 703 drives the rotating shaft 702 fixedly connected thereto to rotate, and the rotating shaft 702 then drives the gear 704 fixedly connected thereto to rotate, so that the gear 704 drives the gear rod 706 meshing therewith to move downward, and cooperates with the hydraulic chamber 1 705 slidably connected to the gear rod 706, so that the pressure in the hydraulic chamber 1 705 increases, and drives the limiting rod 707 slidably connected to the hydraulic chamber 1 705 to move, so that the limiting rod 707 passes through the through slot 708 and is stuck in the interior of the telescopic rod 500, so that the telescopic rod 500 cannot be retracted. At this time, after the thorn rod 600 is inserted into the ground by operating the grip block 100, the telescopic rod 500 will always be in a longer state.

[0029] Embodiment 2

The hydraulic chamber 2 801 is fixedly connected and communicated with the hydraulic chamber 1 705. The side of the hydraulic chamber 2 801 is slidably connected with a pressure plate 802. When the pressure in the hydraulic chamber 1 705 increases, the pressure in the hydraulic chamber 2 801 fixedly connected and communicated with the hydraulic chamber 1 705 increases, driving the pressure plate 802 slidably connected with the hydraulic chamber 2 801 to move. The side of the gripping block 100 is rotatably connected with a torsion spring block 803. The side of the torsion spring block 803 is fixedly connected with a transmission rod 804. The side of the transmission rod 804 is fixedly connected with a protective plate 805. The protective plate 805 is located at the side of the pressure plate 802, and the protective plate 805 contacts the pressure plate 802. When the pressure plate 802 moves, the pressure plate 802 contacts the protective plate 805, and the protective plate 805 is rotatably connected to the holding block 100 through the transmission rod 804 and the torsion spring block 803, so that the protective plate 805 rotates to the side position of the detection pickup 200 with the torsion spring block 803 as the axis. In this case, it provides a certain degree of protection to the detection pickup 200, thereby improving the protection effect of the device on the detection pickup 200.

[0031] During use, on the basis of Example 1, when the pressure in hydraulic chamber 1 705 increases, the pressure in hydraulic chamber 2 801 fixedly connected and communicated with hydraulic chamber 1 705 increases, driving the pressure plate 802 slidingly connected to hydraulic chamber 2 801 to move, and the pressure plate 802 contacts the protective plate 805, and the protective plate 805 is rotatably connected to the holding block 100 through the transmission rod 804 and the torsion spring block 803, so that the protective plate 805 rotates to the side position of the detection pickup 200 with the torsion spring block 803 as the axis, and in this case provides it with certain protection.
