[0030] In the present invention, when it is necessary to stretch the fixed platform 12, by starting the double-headed motor 41, its output shaft drives the two screw rods 2 40 to rotate, and the two screw rods 2 40 will drive the two connecting blocks to move forward during the rotation, and the two connecting blocks will simultaneously drive the two stretching plates 39 to stretch, thereby realizing the stretching function of the fixed platform 12, making the stretching process of the fixed platform 12 more stable and uniform, and ensuring the precision and quality of stretching. When it is necessary to lift the pushing mechanism, by starting the driving motor 13, its output shaft drives the screw rod 3 14 to rotate, and the screw rod 3 14 will drive the L block 15 to move upward during the rotation, and the L block 15 will At the same time, the lifting rod 10 is driven to move upward, and the lifting rod 10 can be raised and lowered. The lifting rod 10 slides in the fixed barrel 11. If the driving motor 13 rotates in the opposite direction, the screw 3 14 rotates in the opposite direction, and the L block 15 moves downward, thereby driving the lifting rod 10 to descend, completing the entire lifting process. When the interpolation needle 16 needs to be pushed into workstations at different heights, the pushing mechanism can be accurately adjusted to the appropriate height to improve production efficiency and product quality. First, the interpolation needle 16 is placed in the groove 38. The interpolation needle 16 is a hollow needle that can be inserted into human tissue. The top end is a sealed tip. The material is medical-grade stainless steel. Its outer diameter is 1.5mm-2mm and the inner diameter is 1.1-1.4mm, 100-200mm in length, and equipped with a needle core, which makes it easy to push it deep into the tissue. By starting the hydraulic cylinder 19, its output shaft pushes the connecting plate 20 to move backward, and the connecting plate 20 will simultaneously drive the rack 21 and the movable plate 18 to move backward. During the movement of the rack 21, the gear 22 will be driven to rotate, the gear 22 will drive the rotating shaft 23 to rotate, the rotating shaft 23 will drive the first sprocket 24 to rotate, and the second sprocket 26 will be driven to rotate through the chain 25, and the second sprocket 26 will drive the rotating rod 27 to rotate, the rotating rod 27 will drive the first bevel gear 28 to rotate, the first bevel gear 28 will drive the second bevel gear 29 to rotate, the second bevel gear 29 will drive the rotating rod 30 to rotate, and the rotating rod 30 will drive the third bevel gear 31 to rotate. The third bevel gear 31 drives the fourth bevel gear 32 to rotate, and the fourth bevel gear 32 drives the threaded rod 33 to rotate. When the threaded rod 33 rotates, it cooperates with the thread on the support frame 34 to drive the support frame 34 to move forward. The support frame 34 also drives the clamping plate 35 to move forward, thereby clamping the interpolation needle 16, which can ensure that the interpolation needle 16 is stably fixed in the groove 38, avoiding shaking or displacement in subsequent operations, and improving the accuracy and safety of the operation. The interpolation needle 16 made of medical-grade stainless steel has good biocompatibility and corrosion resistance, which can ensure safety when inserted into human tissue. After completing the clamping of the interpolation needle 16, when it is necessary to push the interpolation needle 16 into When inserting the human body, the operator pushes the push rod 6 to move forward. During the forward movement, the push rod 6 will push the screw 5, the slider 4 and the clamped interpolation needle 16 forward together. When the angle of the pushing mechanism needs to be adjusted, the operator rotates the pin barrel 1 to adjust the angle, which will simultaneously drive the universal joint 9 to rotate and adjust the pushing mechanism to a suitable angle to meet the pushing requirements of the interpolation needle 16 in different parts and directions. After completing the clamping of the interpolation needle 16, when the interpolation needle 16 needs to be pushed into the human body, the operator pushes the push rod 6 to move forward. During the forward movement, the push rod 6 will push the screw 5, the slider 4 and the clamped interpolation needle 16 together. During forward movement, the spring plate 3 is compressed, elastically deforming and storing elastic potential energy. Simultaneously, the slider 4 is pushed forward, and the stopper 7 limits the range of movement, preventing the slider 4 and interpolation needle 16 from being pushed excessively, ensuring the safety and accuracy of the insertion process. A scale 2 is mounted on the device, allowing the operator to adjust the push stroke according to actual needs by observing the scale 2. This allows precise control of the push distance of the interpolation needle 16, ensuring it remains within a controllable range. The interpolation needle 16 is inserted into the body under the push of the push rod 6. After insertion, the interpolation needle 16 is moved away from the body. A single insertion stroke typically ranges from 1 cm to 3 cm, with 5 cm being the limit. In actual practice, such a long insertion stroke is rarely used. Example 2

[0031] The difference between this embodiment and the first embodiment is that a pad is fixedly installed at the bottom of the fixing platform 12, which can prevent the fixing platform 12 from directly contacting the ground.
