Through this segmented transmission structure, the slider can be accurately transmitted in different directions. The design of each part is connected to the adjacent part, so that the movement path of the slider can be realized on the guide rail. The design of the first steering part and the second steering part allows the movement direction of the slider to be adjusted. In turn, the angle of the slider is adjusted by a primary steering until it enters the vertical transmission part.

The slider 2 in the horizontal state can be rotated to an inclined, vertical or reverse parallel state after the turn, and then restored to the original horizontal position for transmission through a secondary turn.

[0041] The connecting assembly 4 includes a transmission base 41, a first connecting rod 42, a telescopic connecting rod 43, a second connecting rod 44 and a connecting base 45. One end of the transmission base 41 is connected to the driving assembly 3 and the other end is hinged to the first connecting rod 42.

[0043] The cross-sectional shape of the guide rail 1 is an I-shaped, and the guide rail 1 includes a sliding portion 5, a connecting portion 6 and a mounting portion 7, wherein the sliding portion 5 is connected to the mounting portion 7 via the connecting portion 6; the slider 2 is slidably arranged on the sliding portion 5.

In this embodiment, the guide rail 1 with an I-shaped cross-section has good rigidity and stability and can provide stable sliding support. The sliding portion 5 includes a sliding plane 51, an upper curved surface 52, a flange 53, a lower curved surface 54 and a retaining inclined surface 55. Through these designs, the slider 2 can slide smoothly on the guide rail 1, reducing friction and vibration during sliding. The slider 2 is provided with a transmission retainer 21, and the transmission retainer 21 includes a transmission slide 211 and a retaining clamp 212. The transmission slide 211 cooperates with the sliding plane 51, the upper curved surface 52, the flange 53 and the lower curved surface 54 to realize the transmission function of the slider 2.

In this embodiment, the first turning part 12 and the second turning part 14 are twisted in a spiral shape, and the multi-directional adjustment capability of the slider 2 on the guide rail 1 can be achieved by adjusting the twisting angle. This design enables the slide rail to adapt to different work requirements and space limitations, and realize a more flexible and diverse motion path. The closed-loop annular track ensures the stability and continuity of the slider 2 during the sliding process. The slider 2 can move continuously on the circular track, avoiding the situation where the slider 2 is detached from the guide rail 1 or the sliding is interrupted. Through the design of the closed-loop circular track, the slider 2 can perform precise motion control on the guide rail 1. Whether it is the linear transmission part, the steering part or the return part, they have all been optimized to ensure the stability and accurate position control of the slider 2. This precise motion control makes the slide rail suitable for application scenarios that require high-precision positioning and motion control. The structure of the closed-loop circular track makes the entire slide rail system more stable. By connecting the circular tracks of various parts, the load and force can be effectively dispersed, and the structural stability of the entire slide rail system can be improved. This enhanced structural stability can reduce the vibration and deformation of the slide rail during movement, and improve the reliability and service life of the slide rail.
