Description

Technical Field

[0001] The utility model relates to the field of samplers, in particular to a high-cold meadow plant root sampler. Background Art

[0002] Alpine meadow plants refer to plants that can adapt to high-cold environments. They usually grow in areas with higher altitudes. Their roots are shallow and form dense clumps to adapt to unstable soil and cold environments. Since the roots of plants grow in the soil, if you want to study the plant roots and extract some effective and sufficient ones for medical use, you must first sample the plant roots.

[0003] For example, a plant root sampler disclosed in the utility model with authorization announcement number CN218212047U comprises a sampling mechanism, a pressing mechanism and a fixing mechanism. The pressing mechanism is connected to the upper side of the sampling mechanism, and the fixing mechanism is sleeved on the outer ring of the pressing mechanism. The pressing mechanism comprises a rotating rod, a pressing handle, an anti-slip pad, a rotating wheel and a rotating handle. The sampling tube is placed in the area where sampling is required, and then the foot is stepped on the support leg, and then the rotating rod is driven to rotate by the rotating wheel and the rotating handle. The rotating rod drives the sampling tube to move downward through the thread action to sample the sampling area. After the sampling is completed, the rotating rod is reversed through the rotating wheel and the rotating handle, so that the rotating rod drives the sampling tube to rise through the thread action, thereby eliminating the need to press the device down by hammering, reducing safety hazards, and also facilitating the staff to perform sampling work.

[0004] However, when the device is in use, the overall length of the device is fixed and cannot be adjusted according to the height of the user. In addition, the length is fixed and cannot be folded, making it inconvenient to carry around during actual use. Utility Model Content

[0011] As a preferred technical solution of the utility model, a connecting handle is connected to the top end of the lifting rod, and an anti-slip handle is connected to both ends of the connecting handle.

[0012] Compared with the prior art, the utility model can achieve the following beneficial effects:

[0013] The limited rotation adjustment of the rotating shaft is achieved through the coordination of the worm wheel and the worm, and the rotating shaft with limited rotation adjustment drives the gear to rotate and adjust, and the meshing of the rotation-adjustable gear and the rack makes the lifting rod be adjusted in the rotating rod, so as to adjust the overall height of the device. The setting of this structure can adjust the overall height of the device at will according to the height requirements of the staff, and when not in use, the lifting rod can be stored and moved into the rotating rod, so as to reduce the volume of the entire device, thereby facilitating the movement and carrying of the device and improving the practicability of the device.

[0022] When the lifting rod 6 is adjusted to be lifted and lowered so as to adjust the overall height of the device, the adjusting knob 15 is first used to rotate and adjust the rotating rod 13 and the worm 12, and then the rotating shaft 9 and the gear 8 arranged outside the rotating shaft 9 are rotated and adjusted by engaging the rotating and adjusted gear 8 with the rack 7, so that the lifting rod 6 is adjusted to be lifted and lowered in the rotating rod 2, and the length of the lifting rod 6 extending out of the rotating rod 2 can be adjusted according to the height requirements of the staff, and when not in use, the lifting rod 6 can be stored and moved into the rotating rod 2, thereby reducing the volume of the entire device, making it convenient to move and carry the device, and improving the practicality of the device;

[0023] As a further implementation of this embodiment, Figure 1-4 As shown, a thread pattern is provided on the outer wall of the rotating rod 2, and then a thread sleeve 4 is connected to the thread sleeve on the outer side of the rotating rod 2, and an internal thread is provided on the inner wall of the thread sleeve 4 to be screwed with the thread of the rotating rod 2, and then four legs 3 are provided on the outer wall of the thread sleeve 4, and a connecting handle 16 is connected to the top of the lifting rod 6, and finally a non-slip handle 17 is connected to both ends of the connecting handle 16;

[0024] Specific working principle:

[0025] When the device is used for the root system of alpine meadow plants, the overall height of the device is first adjusted according to the height requirements of the staff. When adjusting, the rotating rod 13 and the worm 12 are first rotated and adjusted through the adjusting knob 15, and then the rotating shaft 9 and the gear 8 arranged on the outside of the rotating shaft 9 are rotated and adjusted by engaging the rotating and adjusted gear 8 with the rack 7.
