[0017] Preferably, the method for using the agricultural pest specimen storage device comprises the following steps:

[0018] S1: When collecting and preserving pest specimens, the user first holds the resistance rod and then pulls the L-shaped push rod clockwise, so that the L-shaped push rod squeezes one end of one of the double-headed ball rods to slide in the arc groove, squeezes out the corresponding first conical resistance block from the rectangular groove, and pushes the corresponding second conical resistance block and the U-shaped toothed plate to slide in the L-shaped slide groove. At this time, the U-shaped toothed plate moves leftward to drive the two gears and the connecting plate on the rotating shaft to deflect counterclockwise, so that the two storage boxes on the end of the connecting plate rotate clockwise and move out of the placement groove, and then the user inserts the resistance rod into the third slot in the counterclockwise direction to position the rotated storage box;

[0019] S2: When the storage box rotates 90 degrees following the connection plate, the arc rod drives the insertion rod to slide in the arc slideways of the two limit slideways.

At this time, the U-shaped tooth plate moves left to drive the connecting plate to deflect, driving the two storage boxes corresponding to the second conical resistance block to open, so that the user can store new pest specimens again. When the pest specimens are stored, hold the resistance rod and pull the L-shaped push rod to deflect and reset, so that the first conical resistance block that slides out of the rectangular groove moves right and resets to the rectangular groove, thus completing the reset of the storage box.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] In the present invention, by holding the resistance rod and then pulling the L-shaped push rod clockwise, the L-shaped push rod squeezes one end of one of the double-headed ball rods to slide in the arc groove, squeezes the corresponding first conical resistance block out of the rectangular groove, and pushes the corresponding second conical resistance block and the U-shaped tooth plate to slide in the L-shaped slide groove. At this time, the U-shaped tooth plate moves left to drive the two gears and the connecting plate on the rotating shaft to deflect counterclockwise, so that the two storage boxes on the end of the connecting plate are rotated clockwise and moved out of the placement groove, which is convenient for users to store pest specimens.

[0023] In the present invention, when the storage box rotates more than ninety degrees following the connecting plate, the insertion rod on the arc rod slides into the straight slides of the two limiting slides, so that the insertion rod moves to the side away from the shaft rod, and then cooperates with the two arc plates to pull the two storage boxes in the closed state open, making it convenient for the user to place the pest specimens to be stored in the storage box.

[0024] In the present invention, by rotating the hollow rotating cylinder clockwise, another second conical resistance block is driven to resist the first conical resistance block sliding out of the rectangular groove again. At this time, the U-shaped tooth plate moves leftward to drive the connecting plate to deflect, driving the two storage boxes corresponding to the second conical resistance block to open, so that the user can store new pest specimens again and switch the storage boxes conveniently.

[0048] The use method and advantages of the present invention: The use method of the agricultural pest specimen preservation device has the following working process:

[0049] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown:

[0050] S1: When collecting and preserving pest specimens, the user first holds the abutment rod 62, so that the abutment rod 62 deflects and separates from the first card slot 4 in the counterclockwise direction, and then pulls the abutment rod 62 and the L-shaped push rod 61 clockwise, so that the L-shaped push rod 61 squeezes one of the double-headed ball rods 10 to deflect and slide in the arc groove 11, so that the end of the double-headed ball rod 10 away from the arc groove 11 squeezes the first conical abutment block 9 to slide out of the rectangular groove 8, and pushes the corresponding second conical abutment block 9 to slide out of the rectangular groove 8. The two conical abutment blocks 134 and the U-shaped toothed plate 133 slide in the L-shaped slide groove 132. At this time, the U-shaped toothed plate 133 moves leftward to drive the two gears 136 and the connecting plate 1317 on the rotating shaft 135 to deflect counterclockwise, so that the two storage boxes 138 on the ends of the connecting plate 1317 rotate clockwise and move out of the placement groove 1316. Then, the user inserts the abutment rod 62 into the third slot 4 in the counterclockwise direction to position the rotated storage box 138.

[0051] S2: When the storage box 138 rotates ninety degrees following the connecting plate 1317, the arc rod 1311 drives the insertion rod 1312 to slide in the arc slides of the two limiting slides 1313. When the storage box 138 rotates more than ninety degrees following the connecting plate 1317, the insertion rod 1312 on the arc rod 1311 slides into the straight slides of the two limiting slides 1313, so that the insertion rod 1312 moves to the side away from the shaft 137, and then cooperates with the two arc plates 139 to pull the two storage boxes 138 in the two closed states to open, so that the user can place the pest specimens to be stored in the storage box 138.

[0052] S3: After the pest specimens in the storage box 138 are stored, the user rotates the hollow rotating cylinder 131 clockwise, so that the hollow rotating cylinder 131 cooperates with the connecting plate 1314 to drive the shaft column 1315 to rotate. At this time, the shaft column 1315 drives the limiting plate 121 to rotate. At this time, the end of the second spring telescopic rod 123 is moved out of the V-shaped groove 122 and then inserted into the V-shaped groove 122 on the rotating limiting plate 121 again, thereby limiting the rotating limiting plate 121 to ensure the consistency of the rotation angle of the hollow rotating cylinder 131 each time;

[0053] S4: When the hollow rotating cylinder 131 rotates clockwise, the storage box 138 storing the pest specimens is driven to rotate, so that the second conical resistance block 134 on the right side of the storage box 138 is separated from the first conical resistance block 9 that slides out of the rectangular groove 8. At this time, the separated second conical resistance block 134 is pushed to move rightward by the restoring force of the restoring spring telescopic rod 1318, so that the U-shaped tooth plate 133 drives the rotating shaft 135 to rotate counterclockwise, so that the two storage boxes 138 are closed and reset, and stored in the placement groove 1316, completing the placement and storage of the pest specimens;

[0054] S5: When the hollow rotating cylinder 131 rotates clockwise, it drives another second conical abutment block 134 to abut against the first conical abutment block 9 that slides out of the rectangular groove 8 again. At this time, the U-shaped tooth plate 133 moves leftward to drive the connecting plate 1317 to deflect, driving the two storage boxes 138 corresponding to the second conical abutment block 134 to open, so that the user can store new pest specimens again;

[0055] When the pest specimens are stored, the L-shaped push rod 61 is pulled by holding the abutment rod 62 to deflect and reset, so that the first conical abutment block 9 that slides out of the rectangular groove 8 moves rightward and resets into the rectangular groove 8, thus completing the reset of the storage box 138;

[0056] When the user needs to find the corresponding pest specimen, first rotate the screw 2 to separate one end of it from the chuck 3, then press and rotate the hollow rotating cylinder 131 with one hand, and rotate the chuck 3 counterclockwise with the other hand, so that the chuck 3 drives the multiple double-headed ball rods 10 to deflect, and then the multiple first conical resistance blocks 9 at the ends of the multiple double-headed ball rods 10 slide out of the multiple rectangular grooves 8. At this time, all the storage boxes 138 in a group of two are rotated ninety degrees and moved out of the placement groove 1316, and then the screw 2 is rotated again to fix the rotated chuck 3, and the removal of all storage boxes 138 is completed, which is convenient for users to find.

[0057] The above shows and describes the basic principles, main features and advantages of the present invention. Technical personnel in this industry should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not used to limit the present invention.
