[0035] Working Principle: When used, motor 1 (4) plays a core role through precise drive control. The rotation of the motor drives rectangular rod 1 (19) to rotate, which in turn transmits power to rectangular rod 2 (21) fixed to rotating shaft 2 (20). The rotation of rectangular rod 2 (21) drives the sliding movement of its ends, causing sliding rod 24 to move in the track. This movement further acts on circular gear 2 (27), causing it to rotate. Circular gear 2 (27) is meshed with sliding rack 2 (28), pushing sliding rack 2 (28) up and down. The up and down movement directly drives the extension and retraction of rectangular column 3 (30), and the system can be fine-tuned to achieve optimal performance and efficiency. Through this precise mechanical transmission and hydraulic control, optimal hydraulic performance is achieved.

[0036] Secondly, the power provided by Motor 2 (17) continuously drives the rotation of the drive shaft. This rotation, through a series of precise mechanical connections, propels the movement of the robotic arm. The rotation of the robotic arm, in turn, drives the movement of Shaft 12, causing Pin 13 to slide within Rectangular Slot 14. The sliding motion of Pin 13 rotates Circular Gear 11, which in turn propels Sliding Rack 10 up and down on Support Plate 31. The up-and-down movement of Sliding Rack 10 in turn pulls Rectangular Column 19, achieving its own up-and-down displacement, ultimately driving the movement of Blocking Plate 8. This complex motion transmission system not only enables the precise adjustment and control of the movement of each component of the entire device, but also improves the overall efficiency and stability of the system through effective force transmission.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
