[0002] In modern plant science research and ecological monitoring, the collection of plant samples is one of the basic tasks. Traditional plant sampling methods usually rely on tools such as scissors and knives, which are cumbersome to operate and require in-depth collection inside the plant clusters. In some harsh environments, this method is not only inefficient but also may pose safety hazards to collectors, such as allergic reactions, scratches, insect bites and other problems.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood through specific situations.

[0022] The present utility model provides a portable plant sample sampling device. Please refer to Figures 1 to 4 , which includes a shearing mechanism 1 and a plant basket 2 arranged on one side of the shearing mechanism 1; the shearing mechanism 1 includes an outer cylinder 101, a fixed handle 102 arranged at one end of the outer cylinder 101, an upper cutter head 103 arranged at the other end of the outer cylinder 101, a connecting rod 104 arranged inside the outer cylinder 101, a movable handle 105 arranged at one end of the connecting rod 104, and a lower cutter head 106 arranged at the other end of the connecting rod 104.

[0023] The fixed handle 102 includes a movable cavity 102a disposed inside thereof, and hinge holes 102b disposed on both sides of the movable cavity 102a; the fixed handle 102 and the movable handle 105 are hinged by a pin 3, and a spring 4 is provided therebetween for buffering; the connecting rod 104 is also hinged to the movable handle 105; the upper cutter head 103 includes a fixed handle 103a inserted into the outer cylinder 101, a threaded hole 103b disposed outside the fixed handle 103a, an arc-shaped groove 103c disposed on one side of the upper cutter head 103, and a first through hole 103d disposed below the arc-shaped groove 103c; the lower cutter head 106 includes a second through hole 106a penetrating through its surface, and a third through hole 106b disposed below the second through hole 106a; the connecting rod 104 includes a fourth through hole 104a disposed at one end thereof; the first through hole 103d and the third through hole 106b are fixedly connected by a first pin shaft 5; the arc-shaped groove 103c, the second through hole 106a, and the fourth through hole 103a are connected by a second pin shaft 6; the plant basket 2 includes a fixed block 201, and a collection basket 202 disposed on one side of the fixed block 201; the fixed block 201 is fixedly installed outside the upper cutter head 103, and the collection basket 202 is located below the upper cutter head 103 and the lower cutter head 106.

[0024] It should be noted that the fixed handle 102 is fixed to the end of the outer cylinder 101. The upper cutter head 103 is fixedly installed at the other end of the outer cylinder 101 by a screw passing through the outer cylinder and the threaded hole 103b. The lower cutter head 106 is installed on the side of the upper cutter head 103 through the second through hole 106a and the third through hole 106b, and is closely attached to ensure the shearing force. The second through hole 106a, the arc-shaped groove 103c, and the fourth through hole 104a are sequentially connected by the second pin shaft 6. The structures of the first pin shaft 5 and the second pin shaft 6 are mainly composed of slender cylindrical elements, located at the hinge joints of the two blades, and there are protrusions at both ends to limit the blades and prevent them from detaching.

[0025] Preferably, the collection basket 202 is made of woven materials. For example, willow is lighter and breathable, or bamboo strips are more environmentally friendly and sturdy. The fixed block 201 is used to fix the collection basket 202 below the cutter head, and can be fixed by means of adhesion or a fixture to ensure that the plant basket 2 does not easily detach during the shearing operation.

[0026] The working process of this device is as follows: Before collection, hold the plant basket 2 with its opening facing directly upward in hand, move the cutting edge to the stem or root of the plant to be collected, and manually squeeze the movable handle 105 towards the fixed handle 102. At this time, the fixed handle 102 will pull the connecting rod 104 to move towards the handle side of the outer cylinder 101. Due to the limitation between the two cutting heads, the connecting rod 104 can only pull the second pin shaft 6 to move along the arc-shaped groove 103c track, and the lower cutting head 106 will be tightened. The cutting edges of the two come into contact to achieve shearing. Subsequently, the manual squeezing stops, and under the action of the spring 4, the movable handle 105 returns to its original position. Similarly, the cutting edges unfold. Repeating this action can achieve continuous shearing. After the shearing is completed, the required plant samples will fall into the plant basket 2 under the influence of gravity, completing the collection of the plants.

[0027] In summary, the portable plant sample sampling device of the present utility model is collected through a long-handled shearing mechanism 1, which can reduce the direct contact between the collector and the plant, and can reduce the safety risk. In addition, the bottom is provided with a collection basket 2 to directly collect the sampled plants integrally, avoiding the risk of sample dropping or damage. The device is simple to operate, safe and convenient.

[0028] The above description is only a description of the preferred embodiments of the present utility model, and does not limit the scope of the present utility model in any way. Any changes and modifications made by those of ordinary skill in the art of the present utility model according to the above disclosure shall fall within the protection scope of the claims.
