DETAILED DESCRIPTION

[0025] like Figure 1-5 In the invention, a tool for collecting small insects by using static electricity includes a storage tube 1 and a driving rod 2. The storage tube 1 is provided with a conical hole 101, and the inner wall of the conical hole 101 is provided with a contact sleeve 3. The driving rod 2 includes a conical rod body 201, and the conical rod body 201 is inserted into the conical hole 101. Static electricity is generated by the friction between the conical rod body 201 and the contact sleeve 3, so that the conical rod body 201 can take out small insects from a test tube. In the process of agricultural and forestry production, the prevention and control of small insects is a very important topic. Since small insects are small, it is inconvenient for staff to take samples. When traditionally using gloves for sampling, not only is the operation troublesome, but it may also damage the integrity of small insects, which is not conducive to the subsequent work in the laboratory. This scheme adopts a non-contact method, and uses the relative friction movement between the driving rod 2 and the contact sleeve 3 in the storage tube 1 to generate static electricity, so that the driving rod 2 with electric charge attached can adsorb and guide small insects to a certain extent, improve the overall sampling efficiency, reduce the difficulty of sampling, and provide a strong guarantee for the integrity of the sample.

[0026] In the preferred solution, the end of the first annular stopper 102 is provided with a first annular stopper 102, the first annular stopper 102 and the step 103 are connected to form the step 103, and the end of the cone rod body 201 is provided with a pressure plate 207, and the pressure plate 207 and the step 103 are plugged. The inner side wall of the step 103 is circular, and the outer diameter of the pressure plate 207 matches the inner diameter of the step 103, thereby ensuring convenient picking up, and the step 103 plays a positioning role, ensuring smooth cooperation between the driving rod 2 and the contact sleeve 3, and good friction rotation effect.

[0027] like Figure 6-8 In the preferred embodiment, a round rod 205 is provided on one side of the pressure plate 207, a locking sleeve 203 is sleeved on the round rod 205, a spring 215 is provided between the locking sleeve 203 and the pressure plate 207, and the first annular stopper 102 and the locking sleeve 203 are threadedly connected.

[0028] When in use, the lock sleeve 203 and the first circular stopper 102 cooperate to ensure that the driving rod 2 and the storage tube 1 are relatively fixed, and the overall fixing effect is good, avoiding the problem of parts falling off due to separation under the action of external force. The overall structure is small and occupies little space. The spring 215 plays a role in resetting the lock sleeve 203, and at the same time ensures that the fixation between the lock sleeve 203 and the first circular stopper 102 is more firm and reliable.

[0029] In a preferred solution, the outer diameter of the locking sleeve 203 matches the outer diameter of the storage tube 1. Setting the same outer diameters provides a good overall visual effect, good consistency, and more convenient manufacturing.

[0030] In the preferred embodiment, the end of the storage tube 1 is provided with a chamfer 105, and the end of the cone rod 201 is provided with a rounded corner 204. This makes it easier for the staff to take the product and provides a better hand feel. At the same time, the end of the cone rod 201 maintains a suitable gap with the contact sleeve 3 through the rounded corner 204, making the overall operation smoother.

[0031] In the preferred solution, a removable gripping head 202 is provided on the round rod 205. The gripping head 202 is provided to facilitate the staff to take the driving rod 2, and also facilitate the subsequent guidance of small insects to be more flexible and convenient.

[0032] In the preferred solution, the round rod 205 is provided with a first through hole 206, the gripping head 202 is vertically provided with a third through hole 212 and a fourth through hole 213, the round rod 205 is inserted in the third through hole 212, and the insertion rod 214 is inserted in the fourth through hole 213 and the first through hole 206. The length of the round rod 205 is slightly smaller than the length of the fourth through hole 213, thereby ensuring that the round rod 205 is hidden in the gripping head 202, making it more comfortable to hold. A slot is provided at the end of the round rod 205. When disassembly is required, a screwdriver can be used to align the slot to directly apply force to the round rod 205 from one side and push it out from the other side, and then the gripping head 202 can be removed, and then other components can be removed to complete the replacement or maintenance work.

[0033] In a preferred solution, a second circular stopper 208 is provided on the outer side of the locking sleeve 203, a second through hole 209 is provided through the middle of the locking sleeve 203 and the second circular stopper 208, a third circular stopper 216 is provided at the bottom of the gripping head 202, and the third circular stopper 216 is threadedly connected with the second circular stopper 208. The distance between the third circular stopper 216 and the second circular stopper 208 is greater than the fixed height of the locking sleeve 203 and the first circular stopper 102, so that when the locking sleeve 203 is completely separated from the first circular stopper 102, the second circular stopper 208 on the locking sleeve 203 is further fixed on the third circular stopper 216.

[0034] In a preferred embodiment, a plurality of grooves 218 are provided along the circumferential direction on the outer side of the gripping head 202. The plurality of grooves 218 serve as friction grooves for the staff to grip the driving rod 2, thereby ensuring a good force application effect and convenient operation.

[0035] In the preferred solution, the first annular stopper 102 is provided with a first thread 104 on the outside, the lock sleeve 203 is provided with a second thread 210 on the inside, the first thread 104 and the second thread 210 have the same rotation direction, the second annular stopper 208 is provided with a third thread 211 on the outside, the third annular stopper 216 is provided with a fourth thread 217 on the inside, and the third thread 211 and the fourth thread 217 have the same rotation direction. In actual production, preferably, the first thread 104, the second thread 210, the third thread 211 and the fourth thread 217 are all right-handed threads, so that the overall operation efficiency is higher, the effect is better, and the production is more convenient.

[0036] The above embodiments are only preferred technical solutions of the present invention and should not be regarded as limitations of the present invention. The protection scope of the present invention shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
