DETAILED DESCRIPTION

[0017] Example 1: Reference Figure 1 and Figure 2 , including a clamp 1, a base 2, and a lever driving mechanism 3. The clamp 1 is a cylindrical body with openings at both ends. The inner hole diameter of the clamp 1 is slightly larger than the outer diameter of the probe rod 22. The inner wall of the clamp 1 is provided with upward serrations 4. The clamp 1 is used to be sleeved on the outer periphery of the probe rod 22. The lever driving mechanism 3 is arranged on the base 2. The lever driving mechanism 3 is connected to the clamp 1. The lever driving mechanism 3 is used to drive the clamp 1 to move up and down.

[0018] The lever driving mechanism 3 includes a vertical rod 5, a driving rod 6, a sleeve 7, and a connecting rod 8. The vertical rod 5 is arranged on the base 2. One end of the sleeve 7 is hinged to the side wall of the clamp 1. The other end of the sleeve 7 is hollow and is sleeved on the driving rod 6. One end of the connecting rod 8 is hinged to the vertical rod 5. The other end of the connecting rod 8 is sleeved on the sleeve 7 through a connecting ring 9.

[0019] An annular retaining strip 10 is provided on the outer wall of the sleeve 7 , and the annular retaining strip 10 is used to prevent the connecting ring 9 from sliding out of the sleeve 7 .

[0020] The side wall of the clamp 1 is hingedly connected to the sleeve 7 via the connecting ear 11 .

[0021] The base 2 is made of steel plate.

[0022] When in use, first place the base 2 on a relatively flat and solid ground near the probe rod 22, put the clamp 1 on the probe rod 22, and slide the clamp 1 to the position where the probe rod 22 is close to the ground, then insert the drive rod 6 into the hollow end of the sleeve 7, adjust the position of the clamp 1, so that the drive rod 6 is in an appropriate position, press the drive rod 6 downward, so that the drive rod 6 drives the clamp 1 to pull the probe rod 22 upward. When the drive rod 6 is pressed down, due to a certain angle between the clamp 1 and the probe rod 22, the serrations 4 on the inner wall of the clamp 1 will tightly clamp the probe rod 22, driving the probe rod 22 to move upward. When the probe rod 22 is pulled out for a certain distance, release the drive rod 6, slide the clamp 1 downward along the probe rod 22, and repeat the process of pressing the drive rod 6 until the probe rod 22 is completely pulled out of the ground.

[0023] Example 2: Reference Figure 3 The difference between this embodiment and the first embodiment is that:

[0024] The lever driving mechanism 3 includes a vertical plate 12, a driving arm 13, a cam 14, a roller 15, a connecting arm 16, and a rotating shaft 17. The vertical plate 12 is arranged on the base 2, and a mounting seat 18 is arranged on the top side of the vertical plate 12. The side wall of the driving arm 13 is hinged on the mounting seat 18, and one end of the driving arm 13 is hinged to the connecting arm 16, the connecting arm 16 is hinged to the clamp 1, and the other end of the driving arm 13 is connected to the roller 15. The rotating shaft 17 is rotatably arranged on the side wall of the vertical plate 12, the cam 14 is fixedly mounted on the rotating shaft 17, and the roller 15 is in contact with the cam 14, and the rotating shaft 17 is connected to a rocker 19.

[0025] A connecting seat 20 is provided on the side wall of the clamp 1 , and the connecting arm 16 is hingedly connected to the connecting seat 20 via a connecting plate 21 .

[0026] When in use, after the clamp 1 is put on the position of the probe rod 22 close to the ground, the rocker 19 is manually rotated, and the rocker 19 drives the rotating shaft 17 to drive the cam 14 to rotate. When the cam 14 rotates to a low position, the cam 14 drives the driving arm 13 and the connecting arm 16 through the roller 15 to drive the clamp 1 to pull the probe rod 22 upward. When the probe rod 22 is pulled out a certain distance, the clamp 1 is slid downward along the probe rod 22, and the process of rotating the rocker 19 is repeated until the probe rod 22 is completely pulled out of the ground.

[0027] The rod is pulled out by hand cranking, which makes the operation more convenient and labor-saving.

[0028] The above detailed description is a specific description of a feasible embodiment of the utility model. The embodiment is not intended to limit the patent scope of the utility model. Any equivalent implementation or modification that does not deviate from the utility model should be included in the patent scope of this case.
