[0044] Working principle: the motor 204 is fixed on the connecting plate 203 as the power source, and the connecting plate 203 provides stable support by connecting with the top of the hollow pipe 201. When the motor 204 starts, its output end transmits torque to the connecting rod 206, which acts as an intermediate power transmission medium, directly transmitting the power of the motor 204 to the gear 205 fixed in the middle, driving the gear 205 to start rotating. In the rotation transmission stage, the outer wall of the gear 205 is engaged with the multiple clamping strips 202 inside the top of the hollow pipe 201, which not only limits the movement track of the gear 205, but also converts the rotary motion of the gear 205 into the overall rotary power of the mechanism through engagement. The hollow pipe 201, as the core support component, not only provides installation space for the internal clamping strip 202 and gear 205 transmission assembly, but also ensures the basic stability of the entire mechanism through the fixed connection of its left side with the square plate 1, avoiding shaking during rotation. The partition plate 207 outside the gear 205 is fixed on the top of the hollow pipe 201, separating the gear 205 from the external space, preventing dust and foreign matter from entering the transmission area and affecting the engagement precision, and ensuring the smoothness of the transmission process. In the mold operation stage, the hollow pipe 201 inside the workbench 208 with a port is the reference surface for mold installation. The mold is fixed on the top of the workbench 208 with a port through the replacement assembly 209. When the gear 205 drives the mechanism to rotate, the workbench 208 with a port rotates synchronously with the hollow pipe 201, thereby driving the installed mold above to complete the rotary motion. The replacement assembly 209 can quickly replace molds of different specifications according to needs during this process, improving the versatility of the equipment and ensuring stability. In the stable guarantee stage, the fixed assembly 210 at the bottom of the hollow pipe 201 cooperates with the square plate 1 to strengthen the overall stability of the mechanism from the bottom, avoiding the decrease of positioning accuracy due to the offset of the center of gravity during rotation. The rigid connection of each component further ensures the efficiency of power transmission, reduces transmission loss, and finally realizes the accurate rotation of the mold on the preset track, meeting the needs of processing or positioning operation. The hollow pipe 201, as a support and space carrier, connects the four modules of power input, transmission, operation, and stability in series. Each component has clear division of labor, and together they ensure the efficient and stable operation of the rotary mechanism 2 from power input to mold action.

[0045] And, the connecting rod two 301 as the core support component, its left side is fixed in the middle of the square block plate 1, forms the stable base of the whole mechanism, provides rigid support for the subsequent adjustment action, the circular groove 302 opened in the front side provides the installation reference for the hollow pipe two 303, ensures that it is fixed coaxially with the connecting rod two 301, avoids the influence of the precision due to the deviation of components in the adjustment process, when the pressure needs to be applied to the workpiece, the operator applies the rotary force through the twist handle 308, the force is transmitted to the threaded rod 305 fixed with it, makes it rotate along the axial movement, the threaded filiform 304 in the hollow pipe two 303 plays a key role in the precise engagement of the inner wall thread with the outer thread of the threaded rod 305, converts the rotary motion into the linear lifting motion of the threaded rod 305, when the handle is rotated clockwise, the threaded rod 305 moves downward along the threaded trajectory, and when it is rotated counterclockwise, it is reset upward, realizing the bidirectional adjustment of the pressure, with the linear motion of the threaded rod 305, the bottom fixed compression block 306 moves synchronously until it contacts with the surface of the workpiece, the compression block 306 as the force executing component, directly applies the pressure transmitted by the threaded rod 305 to the workpiece, forms the preset shape through extrusion, the protective layer 307 at the bottom of the compression block 306 buffers the pressure impact in the process, avoids the scratches or deformation of the surface of the workpiece due to the hard contact, reduces the wear of the compression block 306 itself, prolongs the service life of the whole mechanism, the precise cooperation of the threaded filiform 304 and the threaded rod 305 ensures the adjustment accuracy, the operator can realize the fine adjustment of the pressure by controlling the rotation angle of the twist handle 308, meets the forming process requirements of different workpieces, when the pressure reaches the process requirement, stop rotating the handle, the self-locking effect generated by the threaded engagement makes the threaded rod 305 keep the current position, the compression block 306 stably applies the pressure, ensures the consistency of the shape of the workpiece in the extrusion process.

[0046] Finally, it should be pointed out that: the above only for the preferred embodiments of the utility model, and does not limit the utility model, although the utility model is described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing each embodiment, or equivalent replacement to part of technical features, any modification, equivalent replacement, improvement etc. made within the spirit and principles of the utility model, should be included in the protection scope of the utility model.
