DETAILED DESCRIPTION

[0019] Reference Figure 1-Figure 7 , a plant disease specimen collection device, which comprises a clamping bag 1 and a base arm 3, a fixed shaft 16 is fixed on the base arm, and a hinge plate 15 of the clamping bag is hinged to the fixed shaft;

[0020] The clamp bag comprises two clamps 13, a knife plate 11 is fixed on the top of each clamp, a knife edge is ground on the end of the knife plate, the knife plate and the clamp are fixed by screws, a hinge plate is fixed on the bottom of each clamp, the hinge plate is hinged to the fixed shaft, a cone pocket 12 is fixed between the two clamps, and the two clamps are connected by a spring 14;

[0021] The base arm is covered with an outer sliding arm 4 and slidably cooperates with the outer sliding arm. A limiting frame 2 is fixed on the outer sliding arm. The base arm is threadedly connected with the inner extension rod 7. The outer sliding arm is covered with an extension sleeve 5 and threadedly connected with the extension sleeve.

[0022] The base arm is a hollow tube with a square exterior and a round interior. The base arm has an internal thread, and the inner extension rod has an external thread that matches the internal thread of the base arm, so that the base arm is threadedly connected to the inner extension rod.

[0023] The outer sliding arm is a hollow tube with a square inside and a round outside. The square inside the outer sliding arm matches the square outside the base arm, so that the base arm and the outer sliding arm are slidably matched. The outer sliding arm has an external thread. The extension sleeve is a cylindrical sleeve. The extension sleeve has an internal thread that matches the external thread of the outer sliding arm, so that the extension sleeve is threadedly connected to the outer sliding arm.

[0024] A fixing nut is fixed on the top of the outer end of the extension sleeve, and the outer end sleeve is rotated by holding the fixing nut to adjust the position. A nut is fixed on the bottom of the inner rod, and the position of the inner rod is adjusted by holding the nut. A retaining ring 6 is also fixed on the lower part of the outer end of the extension sleeve, and the retaining ring is used to abut against the hand when the outer end sleeve slides with the outer sliding arm.

[0025] The plant disease specimen collection device, the limit frame includes two circular plates 22 arranged front and back, the two circular plates are connected and fixed by a bottom plate 23, the upper ends of the two circular plates are respectively fixed with push shafts 21, the bottom plate is provided with a circular hole, the outer sliding arm passes through the circular hole on the bottom plate and fixes the bottom plate and the outer sliding arm;

[0026] In the plant disease specimen collection device, a nut 8 is fixed to the bottom of the inner extension rod.

[0027] Working principle: When in use, hold the bottom of the inner extension rod with one hand and the outer extension sleeve with the other hand, and then find the part that needs to be collected. At this time, the two clamping plates of the clamping bag are open under the action of the spring. Adjust the position of the device so that the part to be collected is in the clamping bag, and then push the outer extension sleeve together with the outer sliding arm to slide upward with the hand holding the outer extension sleeve. During the sliding process, the push shaft contacts the clamping plate and pushes the clamping plate to rotate to the middle until the knife plate clamps the root of the part to be collected and then continues to push. The knife plate cuts off the root, so that the collected part falls into the cone pocket, and the sample is collected. The cone pocket is made of soft rubber, fixed to the clamping plate by screws, and can rotate with the clamping plate. The deformation will not affect its use. After the collection is completed, keep this pushing position and transfer the device to the storage box, then slide the extension sleeve together with the outer sliding arm in the opposite direction, and the two clamps will automatically open under the action of the spring, and then store the collected samples for detection. When encountering high-position samples that need to be collected, turn the inner extension rod to make it gradually rotate out until it reaches the required length and stops, thereby extending the arm of the entire device. Since the arm is extended, it will be difficult for the other hand to push the extension sleeve, so hold the fixing nut of the extension sleeve and turn it to make the extension sleeve gradually drop in height, and stop after it drops to a position convenient for arm operation, and then repeat the above steps for sample collection.
