[0027] ​Two fixed assemblies are symmetrically arranged with the axis of the connecting rod as the axis of symmetry, each of the fixed assemblies comprises a connecting chain and a fixed block connected with each other, the connecting chain is connected with the connecting rod, and the fixed block is rotationally arranged on the fixed seat;

[0028] Wherein, under the action of external force, the connecting rod is reversely rotated to have a first state when the connecting rod is rotated in a positive direction and a second state when the connecting rod is reversely rotated, in the first state, the connecting rod lifts up the two connecting chains, and the two fixed blocks are rotationally connected to rotate towards each other to clamp the probe rod therebetween, and in the second state, the connecting rod releases the two connecting chains, and the two fixed blocks are rotationally connected to rotate away from each other to release the probe rod therebetween.

[0029] In the embodiment, in order to facilitate the recovery of the probe rod inserted into the soil, a lifting device is arranged at one end of the probe rod exposed outside the soil, the lifting device comprises a frame arranged in the up-down direction and a connecting rod rotationally arranged on the frame, the connecting rod is used to connect two fixed assemblies on the fixed seat, each of the fixed assemblies comprises a connecting chain and a fixed block connected with each other, the connecting chain is connected with the connecting rod, and the fixed block is rotationally arranged on the fixed seat, before lifting the probe rod, the connecting rod is reversely rotated to rotate the two fixed blocks towards each other, and the fixed seat is sleeved on the rod body of the probe rod exposed outside the soil, then the connecting rod is positively rotated to lift up the two connecting chains to rotationally connect the two fixed blocks to rotate away from each other to clamp the probe rod therebetween, the connecting rod is continuously rotated downward to lift up part of the rod body of the probe rod from the soil, then the connecting rod is reversely rotated to rotate the two fixed blocks towards each other to release the probe rod, and the above-mentioned operation of positively rotating the connecting rod can be repeated to lift up the part of the probe rod buried in the soil, and the device can ignore the length of the probe rod, and the probe rod can be easily recovered by repeatedly rotating the connecting rod in the positive direction and the reverse direction, which saves time and labor and does not require other tools, and the device is simple, small, and portable.

[0030] The opposite end surfaces of the two fixed blocks are each provided with a fixed protrusion, in the first state, the two fixed protrusions abut against the probe rod, and in the second state, the two fixed protrusions are separated from the probe rod.

[0031] In the embodiment, one fixed protrusion is arranged on each of the opposite end surfaces of the two fixed blocks, the two protrusions are used to better contact the probe rod to ensure the position stability of the probe rod when clamped, in the first state, when the connecting rod is positively rotated, the two fixed blocks are rotationally connected to rotate towards each other to tightly contact the two fixed protrusions with the probe rod to effectively clamp the probe rod and ensure the stability of the probe rod in the lifting process, and in the second state, when the connecting rod is reversely rotated, the two fixed blocks are rotationally connected to rotate away from each other to separate the two fixed protrusions from the probe rod to release the probe rod.

[0032] The opposite end surfaces of the two fixed blocks are each provided with an avoiding notch, and the fixed protrusion is located above the avoiding notch.

[0033] In this embodiment, an avoidance gap is arranged on each of the opposite end surfaces of the two fixing blocks, which provides sufficient space for the probe rod to pass smoothly without being blocked when the fixing protrusions are not used to clamp the probe rod. The fixing protrusions are located above the avoidance gap and move towards each other and contact the probe rod when the fixing blocks rotate towards each other to clamp the probe rod. When the fixing blocks rotate away from each other to release the probe rod, the two fixing blocks give way to the probe rod through the avoidance gap and do not hinder the movement of the probe rod.

[0034] The avoidance gap has an inclined section, which is inclined towards the direction of the fixing blocks from the end of the fixing protrusion away from the fixing protrusion.

[0035] In this embodiment, the avoidance gap has an inclined section, which can guide the probe rod to enter or exit between the fixing blocks more smoothly and may also help the positioning of the probe rod during clamping or releasing. When the connecting rod is rotated forward, the two fixing blocks rotate towards each other, the fixing protrusions descend and contact the probe rod to clamp the probe rod. At this time, the inclined section of the avoidance gap does not play a major role because the fixing protrusions have already contacted the probe rod. When the connecting rod is reversed, the two fixing blocks rotate away from each other, and the fixing blocks separate from the probe rod through the inclined section. At this time, the inclined section plays a role in guiding the probe rod to help the probe rod pass through the avoidance gap smoothly.

[0036] The fixing protrusion is provided with a circular arc section for clamping or separating the probe rod.

[0037] In this embodiment, a circular arc section is arranged on the fixing protrusion to increase the smoothness when the probe rod contacts the fixing protrusion and reduce friction and wear during clamping or releasing the probe rod. Further, the fixing protrusion is provided with a rubber pad to increase the friction between the fixing protrusion and the probe rod and prevent slipping.

[0038] The connecting rod is provided with a non-slip handle.

[0039] In this embodiment, the non-slip handle improves the comfort of the operator of the probe rod lifting device, especially when the connecting rod needs to be frequently manually reversed, the design of the non-slip handle can provide a better grip feeling and reduce the risk of hand slipping, making the operation more stable.

[0040] The frame body is provided with a base.

[0041] In this embodiment, in order to increase the stability of the entire lifting device and ensure that it will not be knocked down during operation, a base is arranged at the bottom of the frame body.

[0042] Finally, it is explained that the above embodiments are only used to illustrate the technical solutions of the present application and are not limited. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced by equivalents without departing from the purpose and scope of the present application. The technical solutions of the present application should be covered in the scope of the claims of the present application.
