[0035] Refer to Figure 3 - Figure 4, a trapezoidal plate 9 is fixedly connected to the top side of the inner wall of the square frame 8. T-shaped openings 10 are provided at both the left and right ends of the trapezoidal plate 9, such that the inner parts at both the left and right ends of the trapezoidal plate 9 form inclined T-shaped openings 10. Push components are provided at both the left and right ends of the trapezoidal plate 9. The push components include limit posts 11. The outer parts of the two limit posts 11 are respectively slidably connected to the inner walls at both the left and right ends of the trapezoidal plate 9, enabling the limit posts 11 to slide horizontally. Support columns 12 are fixedly connected to the far sides of the two limit posts 11, for transmitting horizontal forces. Trapezoidal blocks 13 are fixedly connected to the far sides of the two push components. The push components are used to push the trapezoidal blocks 13 to slide. The outer parts of the two trapezoidal blocks 13 are respectively slidably connected to the inner walls at both the left and right ends of the sliding column 2, enabling the trapezoidal blocks 13 to slide horizontally. The outer parts of the two trapezoidal blocks 13 are respectively slidably connected to the inner walls at both the left and right ends of the grip rod 1, for limiting and fixing the trapezoidal blocks 13. The outer parts of the two limit posts 11 are respectively slidably connected to the inner walls at both the left and right ends of the trapezoidal plate 9, enabling the limit posts 11 to slide horizontally. Trapezoidal blocks 13 are fixedly connected to the far sides of the two support columns 12. Multiple triangular openings are provided on both the left and right sides of the inner wall of the grip rod 1, for forming a space to restrict the trapezoidal blocks 13. Multiple square openings 14 are provided on both the left and right sides of the inner wall of the sliding column 2, allowing the trapezoidal blocks 13 to slide.

[0036] Refer to Figure 1 and Figure 5 , a grip frame 15 is fixedly connected to the top end of the sliding column 2, facilitating the staff to hold. A fitting plate 16 is fixedly connected to the top side of the grip frame 15, using a flexible material to fit the palm and reduce the wear caused by direct contact. A grip plate 17 is fixedly connected to the top side of the inner wall of the grip frame 15. The groove at the bottom end of the grip plate 17 fits the fingers, facilitating the staff to hold the grip frame 15. A fixed cylinder 18 is fixedly connected to the outer top end of the grip rod 1, providing a supporting force for the fixed cylinder 18. Limit rings 19 are fixedly connected to both the upper and lower sides of the fixed cylinder 18, for restricting the palm. Multiple rubber rings 20 are fixedly connected to the outside of the fixed cylinder 18, facilitating fitting the palm and avoiding wear. Multiple strip-shaped openings 21 are provided on the outer side of the rubber rings 20, enabling a frictional force to be generated between the rubber rings 20 and the palm, preventing the palm from slipping.

[0037] Refer to Figure 1 and Figure 6, a connecting column 22 is fixedly connected to the bottom side of the grip rod 1, and a threaded column 23 is fixedly connected to the bottom side of the connecting column 22 to provide a supporting force for the threaded column 23. The top end of the threaded column 23 is threadedly connected to a threaded ring 24 to limit the displacement of the threaded ring 24, so that the threaded ring 24 can move up and down and provide a limit. Both the left and right sides of the threaded ring 24 are fixedly connected to side columns 25 to facilitate driving the threaded ring 24 to rotate. A rotating column 26 is rotatably connected to the inner wall of the threaded column 23, and an opening block 27 is fixedly connected to the outside of the rotating column 26 to limit the opening block 27 so that the opening block 27 can rotate. A shovel head 28 is fixedly connected to the bottom side of the opening block 27 to facilitate sampling.

[0038] Working principle: When the staff uses the device and faces a terrain or position that is not conducive to the staff directly, by pushing the sliding rod 5 to slide, the sliding disk 6 can be driven to slide, and then the spring 7 can be compressed, so that the spring 7 can store elastic potential energy, and then a force in the opposite direction is given to the sliding rod 5 for reset. When the sliding rod 5 is pressed, the square frame 8 will also be pushed to slide, so that the trapezoidal plate 9 can be pushed to slide. Using the clear structure inside the trapezoidal plate 9, when the trapezoidal plate 9 slides, it can push the two limiting columns 11 to slide towards the adjacent side, and then drive the trapezoidal block 13 to slide. At this time, the trapezoidal block 13 will slide out of the inside of the grip rod 1 and slide inside the sliding column 2. At this time, a pulling force is applied to the hand holding the sliding rod 5, and then the length of the grip rod 1 and the sliding column 2 spliced together is adjusted according to different terrains. After the trapezoidal block 13 is pulled to the appropriate position, the thrust on the sliding rod 5 is released. At this time, the spring 7 is reset, and the two trapezoidal blocks 13 are pushed to reset and engaged with the inner wall of the grip rod 1 contrary to the operation when pressing, so as to avoid excessive bending and reaching due to the terrain and one's own position relationship, and then reduce the strain caused by excessive operation;

[0039] At the same time, when using the device, hold the outside of the fixed cylinder 18 with the left hand and hold the sliding rod 5 with the right hand. At this time, the palm of the right hand will be in contact with the fitting plate 16. The special material of the fitting plate 16 is used to reduce the wear of the right hand. At the same time, the fingers are in contact with the grip plate 17. The design of the grip plate 17 conforms to the grip posture of the fingers, so that people can easily hold the grip frame 15. And when the left hand holds the outside of the fixed cylinder 18, the left palm will be in contact with the rubber ring 20, so as to reduce the wear caused during sampling. And using the strip-shaped opening 21 opened on the outside of the rubber ring 20, the outside of the rubber ring 20 will be in contact with the left palm, so as to avoid the palm slipping and affecting the sampling progress, and then improve the work efficiency;

[0040] When the sampling is completed or the action of the hoe is required, by pushing the side column 25 to rotate counterclockwise, the external thread of the threaded column 23 can be driven to rotate upward, so that the threaded ring 24 no longer fits with the opening block 27. At this time, by rotating the opening block 27, the shovel head 28 is driven to rotate forward by 90 degrees with the rotating column 26 as the center. Applying a clockwise rotating force to the side column 25 drives the threaded ring 24 to rotate downward on the external thread of the threaded column 23. After the threaded ring 24 fits with the opening block 27 that has rotated 90 degrees, the grip rod 1 and the shovel head 28 are at a 90-degree angle, enabling it to have the usage mode of a hoe, thus improving the functionality of the device. After the opening block 27 drives the shovel head 28 to rotate 180 degrees with the rotating column 26 as the center, at this time, pushing the side column 25 drives the threaded ring 24 to rotate clockwise, so as to drive the threaded ring 24 to fit with the opening block 27 that has rotated 180 degrees, enabling the fixation of the opening block 27. At this time, the shovel head 28 and the grip rod 1 are horizontal, thus completing the folding of the shovel head 28, shortening the diameter of the device, and then facilitating the storage of the device.

[0041] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
