In addition, when the detection end 111 contacts with the soil, the soil is easy to be forced to spread outwards, so that the contact surface between the detection end 111 and the soil is reduced.

Working principle:

when the body 110 is vertically oriented to the ground, the detection end 111 is then moved downwards to make contact with the soil, when the detection end 111 is in contact with the soil, the first side plate 210 is propped against the soil in the accommodating groove 113, when the first side plate 210 moves towards the detection end 111, the first side plate 210 is in contact with the inclined surface of the bolt 224, the bolt 224 moves towards the inside of the slideway 223 under the action of the inclined surface, so that when the first side plate 210 passes through the bolt 224, and after the bolt passes through, the connecting spring 225 rebounds to drive the bolt 224 to reset, the bolt 224 clamps the first side plate 210, at the moment, the connecting rod 211 moves into the chute 410 and presses the driven block 411, the driven block 411 moves downwards to press the compression spring 412 under the influence of the inclined surface, and meanwhile, the straight plate 313 is limited by the contact of the ground with the straight plate 313, the straight plate 313 cannot rotate, and the compression spring 412 is compressed; when the detection is completed and the soil is separated, the stop block 221 is rotated, the stop block 221 is positioned in front of the first side plate 210, the compression spring 412 pushes the transmission block 413 downwards, the transmission block 413 downwards pushes one end of the connecting plate 311, the other end of the connecting plate 311 pushes the transmission rod 213 upwards, at the moment, the transmission rod 213 drives the scraper 212 to upwards move, and the soil on the side wall of the detection end 111 is scraped in the upwards moving process.

When the reset is needed, the transmission block 413 is pushed upwards, the driven block 411 is pushed to move upwards by the compression spring 412 to reset, and friction exists between the compression spring 412 and the driven block 411 and the sliding groove 410, so that the compression spring 412 is prevented from automatically sliding down in the sliding groove 410.

It can be seen that the force of the detection end 111 contacting the soil during detection is used to drive the first side plate 210, and the force is temporarily stored by the compression spring 412, and when the detection is completed, the temporarily stored force acts on the connection plate 311 to drive the scraper 212 to clean the detection end 111, thereby improving the cleaning efficiency.

It should be noted that, as shown in fig. 9, during the cleaning operation, the scraped soil on the side wall of the detection end 111 falls between the straight plate 313 and the handle 120, the straight plate 313 blocks wind, so that the wind can be prevented from blowing the soil to the handle 120, and meanwhile, if the soil falls after the straight plate 313 turns over, the straight plate 313 guides the soil, so that the probability of the contact of the soil with hands is further reduced.

the first is that, as described in the above working principle, the blade 212 is driven by the connection plate 311 after the detection, so that the detection end 111 is cleaned;

the second is to support the main body 110 through the connection plate 311, so that the main body 110 can stay on the ground independently, and the detailed principle is as follows:

the second side plate 320 is pulled to make the connecting post 321 leak from the end of the connecting plate 311, then the connecting plate 311 is pressed down to be close to one end of the straight plate 313, at this time, the other end (i.e. the second side plate 320) is in contact with the transmission block 413, and enters above the bending end at the bottom of the transmission block 413 through deformation of the connecting post 321, at this time, as shown in fig. 10, a triangle structure is formed between the connecting plate 311 and the detecting end 111 to support the body 110, so that people do not need to hold.

That is, the body 110 is supported by the rotation of the connection plate 311, so that a triangle structure is formed among the connection plate 311, the detection end 111 and the soil, so that the handle 120 is not required to be held by people in the detection process to achieve the fixing effect of the body 110, and the fatigue of the people is reduced.

Furthermore, in order to improve the supporting effect on the body 110, one end of the connecting plate 311, which is far away from the second side plate 320, is provided with a transverse plate 322, one end of the transverse plate 322 is fixedly connected with a sliding block 323, one end of the sliding block 323 penetrates into the connecting plate 311 and is in sliding connection with the connecting plate 311, and the length of the connecting plate 311 is increased by pulling the transverse plate 322, so that the supporting stability is improved.
