[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] Example: A handheld seeder, as shown in Figures 1-5, includes a seeder body 1. The seeder body 1 includes a seed box, a transmission structure, a seed metering wheel, and a duckbill-type soil inserter. The seed box is used to store seeds and ensure seed supply during the sowing process. The duckbill-type soil inserter is inserted into the soil by gravity when the seeder body 1 is pressed down, thereby obtaining the required sowing depth. The transmission system includes a pull rod 2, a transmission pin, and a drive ratchet, etc. The transmission system drives the seed metering wheel to rotate and the duckbill-type soil inserter to open and close. The seed metering wheel is responsible for taking the seeds out of the seed box and pressing them into the soil. A certain quantity of seeds are sown. The seeder body 1 has a trough 3 on the side away from the pull rod 2. A sliding rod 5 is slidably connected to the trough 3 by a spring 4. A groove 13 is provided on both sides of the trough 3 along its length. The sliding rod 5 is located at one end in the trough 3 and has a protrusion 14 integrally formed on both sides of the trough 3 along the length of the rotation axis 8. The length of the protrusion 14 is the same as the length of the groove 13. The protrusion 14 is slidably connected in the groove 13, thereby ensuring the stability of the connecting rod when sliding in the trough 3.

[0024] As shown in Figures 1-6, a cylindrical groove 12 is formed on the top surface of the slide groove 3. One end of the spring 4 abuts against the bottom surface of the groove 12, and the end of the spring 4 away from the groove 12 is fixedly connected to the top surface of the sliding rod 5. When the spring 4 is compressed under pressure, and when the pressure is removed, it recovers elastically to drive the sliding rod 5 to slide back and forth in the slide groove 3. A fixed groove 6 is formed on the side of the sliding rod 5 that extends out of the slide groove 3 and is away from the pull rod 2. A movable block 7 is detachably connected in the fixed groove 6. A protrusion 15 is integrally formed on the side of the movable block 7 near the fixed groove 6. The cross-sectional shape of the protrusion 15 is similar to that of the sliding rod 2. The fixed groove 6 has the same cross-sectional shape, so that the second protrusion 15 and the fixed groove 6 can be engaged with each other. The fixed groove 6 has a number of arrayed circular through holes 16 on both sides along its length direction. The second protrusion 15 has a circular through hole 17 along the length direction of the rotating shaft 8. The diameter of the first through hole 16 is the same as the diameter of the second through hole 17. The center of the second through hole 17 and the center of the first through hole 16 on both sides are on the same straight line. The first through hole 16 and the second through hole 17 on both sides are detachably connected by bolts 18 and nuts 19. The moving block 7 can be fixed at the required height of the first through hole 16 by screws and nuts 19.

[0025] As shown in Figures 4-6, a rotating shaft 8 is rotatably connected to the movable block 7. A telescopic rod 9 is slidably connected to both ends of the rotating shaft 8. An arc-shaped recess 20 is formed on the periphery of the telescopic rod 9. A cylindrical groove 21 is formed on the bottom surface of the recess 20, near the side of the movable block 7. A spring 22 is fixedly connected to the bottom surface of the groove 21. A snap-fit ​​piece 23 is fixedly connected to the end of the spring 22 away from the groove 21. A through groove 24 is formed at both ends of the rotating shaft 8, and the telescopic rod 9 is slidably connected within the through groove 24. The inner periphery of the rotating shaft 8... The telescopic rod 9 has an integrally formed arc-shaped protrusion. The peripheral wall of the protrusion abuts against the peripheral wall of the first recess 20, thereby restricting the telescopic rod 9 from rotating within the rotating shaft 8. The outer peripheral wall of the rotating shaft 8 has an integrally formed arc-shaped recess 25, which is located directly above the protrusion. Both the recess 25 and the protrusion are formed by bending the rotating shaft 8. The bottom surface of the recess 25 has several arrayed through holes 26. When the snap-fit ​​23 moves with the telescopic rod 9 and is located directly below the through holes 26, it is driven by the elasticity of the second spring 22 to pass through the through holes 26, thereby restricting the sliding of the telescopic rod 9.

[0026] As shown in Figures 1-6, each of the two telescopic rods 9, at their ends far apart, is rotatably connected to a tire 11 via a bearing 10. The radius of the tire 11 is greater than the distance between the bottom surface of the seeder body 1 and the rotating shaft 8. Therefore, the two tires 11 can support and move the seeder body 1. When the spring-4 is compressed, the seeder body 1 is pressed down. When the pressure is released, the seeder body 1 is lifted up by the elastic restoring force of the spring-4, thereby reducing the force applied to move the seeder body 1 and reducing labor intensity. The distance between the seeder body 1 and the ground can be adjusted by adjusting the fixed height of the moving block 7. The distance between the two tires 11 can be adjusted by adjusting the distance the telescopic rod 9 extends through the through groove 24, thus making it suitable for sowing on different terrains such as flat land, ditches, and hills. The seeder body 1 can be removed by lifting it up until the sliding rod 5 extends out of the through groove 24, which facilitates storage and transportation and improves the practical effect of the seeder body 1.

[0027] Working principle: After pressing the latch 23 and applying a pulling force to the telescopic rod 9, it slides in the through groove 24. When the latch 23 moves together with the telescopic rod 9 and is located directly below the through hole 26, it is driven by the elasticity of the spring 22 to pass through the through hole 26, thereby obtaining the required distance between the two tires 11 according to the terrain. After the protrusions 14 on both sides of the sliding rod 5 are aligned with the grooves 13 on both sides of the sliding groove 3, the end of the sliding rod 5 with the spring 4 is inserted into the sliding groove 3, so that the end of the spring 4 away from the connecting rod abuts against the bottom surface of the groove 12. According to the terrain, the moving block 7 is fixed at the through hole 16 at the required height on the sliding rod 5 by the screw and nut 19, thereby obtaining the required ground clearance of the seeder body 1. At the same time, the two tires 11 provide support and movement for the equipment body.
