[0025] The bracket 2 is installed above the base plate 1. The base plate 1 provides support for the components to be mounted, and the bracket 2 provides support for the sliding sleeve 5 to maintain the stability of the sliding sleeve 5.

[0026] The inner wall of the bracket 2 is connected to a sliding sleeve 5, and the inner wall of the sliding sleeve 5 is slidably connected to a push rod 6. The bottom end of the push rod 6 is connected to a hammer head 7, and the top end of the push rod 6 is connected to a pull ring 8. The sliding sleeve 5 provides support for the push rod 6 and maintains the stability of the push rod 6. The hammer head 7 applies hammering force to the needle-shaped fertilizer, and the pull ring 8 facilitates the movement of the push rod 6.

[0027] The push rod 6 is externally fitted with a first spring 9, which provides power to push the push rod 6 to move downward. At the same time, the push rod 6 moves downward, which provides power for the hammer head 7 to strike the needle-shaped hammer.

[0028] The outer surface of the push rod 6 is slidably connected to the pressure plate 10. The inner side of the sliding sleeve 5 is provided with a slide rail 11 and a threaded section 12. The outer surface of the pressure plate 10 is slidably connected to the inner wall of the slide rail 11. The slide rail 11 provides support and guidance for the pressure plate 10, maintaining the stability of the pressure plate 10 when it moves. The outer surface of the threaded section 12 of the sliding sleeve 5 is threadedly connected to a threaded sleeve 13. A ruler plate 14 is installed inside the sliding sleeve 5. The movement of the threaded sleeve 13 provides power for the movement of the pressure plate 10. After the pressure plate 10 moves, it changes the power output of the spring to the push rod 6. When the threaded sleeve 13 moves, it judges the power output of the first spring 9 by the size on the ruler plate 14.

[0029] A control mechanism 15 is provided above the sliding sleeve 5. The control mechanism 15 controls the release and positioning of the push rod 6. The control mechanism 15 includes a connecting plate 1501, which is connected to the top of the sliding sleeve 5. A rotating shaft 1502 is connected to the upper surface of the connecting plate 1501. A retaining plate 1503 is connected to the outer surface of the rotating shaft 1502. A retaining groove 1504 is opened on the inner side of the push rod 6. The outer surface of the retaining plate 1503 contacts the inner wall of the retaining groove 1504. The rotating shaft 1502 supports the retaining plate 1503 to maintain its stability. The push rod 6 receives the resistance of the retaining plate 1503 through the retaining groove 1504 and pushes the push rod 6 through the retaining plate 1503. Rod 6 provides resistance. A support plate 1505 is connected to the upper surface of the connecting plate 1501. A second spring 1506 is connected to one side of the support plate 1505. The other end of the second spring 1506 is connected to one side of the clamping plate 1503. The support plate 1505 provides resistance to the second spring 1506, and the second spring 1506 provides a pushing force to the clamping plate 1503. When there is no external force pushing the clamping plate 1503, the clamping plate 1503 is always inside the clamping slot 1504. A positioning shaft is connected to the opposite side of the clamping plate 1503 and the support plate 1505. The positioning shaft provides support force to the second spring 1506, maintaining the stability of the second spring 1506.

[0030] The outer surface of the push rod 6 is connected to multiple positioning slide rails 16, which are arranged in a circular array. The inner side of the slide sleeve 5 is provided with positioning grooves 17, which are the same number as the slide rails. The inner wall of the positioning groove 17 is slidably connected to the outer surface of the positioning slide rail 16. The positioning groove 17 guides and limits the positioning slide rail 16, maintaining the stability of the positioning slide rail 16 when it moves. The positioning slide rail 16 provides support for the push rod 6, preventing the push rod 6 from rotating and maintaining the stability of the push rod 6.

One end of the first spring 9 is connected to the upper surface of the force plate 18, and the other end of the first spring 9 is connected to the lower surface of the pressure plate 10. The push rod 6 receives the pushing force of the first spring 9 through the force plate 18, thereby transmitting the elastic pushing force of the first spring 9 to the push rod 6. The magnitude of the elastic force output of the first spring 9 is changed by moving the position of the pressure plate 10.

[0032] Multiple force-applying plates 19 are connected to the outer surface of the threaded sleeve 13, and the multiple force-applying plates 19 are arranged in a circular array. The force-applying plates 19 facilitate the application of power to the threaded sleeve 13 by hand, thereby making it easier to drive the threaded sleeve 13 to rotate. Multiple rollers 20 are rotatably connected to the inner wall of the pressure plate 10, and the multiple rollers 20 are arranged in a circular array. The outer surface of the rollers 20 contacts the bottom end of the threaded sleeve 13. The rollers 20 have a rotation function. The pressure plate 10 contacts the threaded sleeve 13 through the rotation of the rollers 20, reducing the friction between the pressure plate 10 and the threaded sleeve 13, and making it easier for the threaded sleeve 13 to push the pressure plate 10 to move its position.

[0033] In use, the following steps are taken: First, the pressure plate 10 is moved by rotating the threaded sleeve 13 through the force plate 19. While the pressure plate 10 is moving, it compresses the first spring 9, changing the spring force output of the first spring 9. At the same time, the hammering force of the hammer head 7 is adjusted. Then, the push rod 6 is moved upward by the pull ring 8. While the push rod 6 is moving upward, the first spring 9 is compressed by the force plate 18. Then, the slot 1504 contacts the plate 1503 to restrict the movement of the push rod 6. Then, the needle-shaped fertilizer is placed in the center of the testing platform 3. Then, the protective cover 4 is placed on the testing platform 3 to prevent the broken needle-shaped fertilizer from splashing everywhere. Then, the plate 1503 is pushed to disengage from the slot 1504, releasing the positioning restriction on the push rod 6. Then, the first spring 9 pushes the hammer head 7 to hammer the needle-shaped fertilizer through the push rod 6.
