Technical Field

[0001] The utility model relates to the technical field of soil sampling, and more specifically to a portable surveying and sampling device. Background Art

[0002] Sampling refers to the process of extracting individuals or samples from the population, that is, the process of testing or observing the population, while surveying sampling refers to the soil sampling work carried out in land surveying. When conducting surveying and sampling in some remote field sites, staff often use portable soil samplers for sampling;

[0003] At present, common portable soil samplers are mainly composed of four parts: a sampling tube, two handles, a foot pedal, and an ejector. When sampling, the sampling tube is inserted into the ground, and then the two handles are pressed and the foot pedal is stepped on to insert the sampling tube into the soil. After the sampling is completed, the two handles are pulled out to pull the sampling tube. At this time, the sample in the sampling tube can be pushed out by the ejector. During the entire operation process, the staff needs to press and pull the handles, so the ease of use of the handles is more important. However, the handles equipped with existing portable soil samplers are mostly fixed. The distance between the two hands of the staff when grasping the handles is fixed, and the operating habits of different staff are different. The fixed handles may make some staff members uncomfortable during operation and are not suitable enough. Therefore, it is urgent to design a portable surveying and mapping sampling equipment to solve the above problems. Utility Model Content

The sliding of the sliding column 601 will drive the square rod 606 and the sliding plate 605 to slide, and then drive the spring 604 to slide synchronously. After the adjustable handle 501 is adjusted to the desired position, the sliding column 601 will also slide to the position of the corresponding first locking hole 403. At this time, the pressing plate 603 is released, and the spring 604 is released, which will push the sliding column 601 to slide outward. When the sliding column 601 is engaged between the corresponding first locking hole 403 and the second locking hole 503, the adjustable handle 501 can be locked again.
