[0007] Further, the lubricating assembly includes a sliding groove arranged on the side of the mobile block, a sliding block is installed on the mobile block, a spring is installed on the side of the sliding block, one end of the spring is connected with the sliding groove, a sealing plug one is installed on the side of the mobile block in the flow guide groove.

[0008] Further, the sliding block is slidably connected with the sliding groove, and the side of the mobile block is provided with an inclined surface.

[0009] Furthermore, the support plate is provided with an oil storage tank, which is connected to a pair of guide channels, and a sealing plug is installed at the top oil filling port of the oil storage tank.

[0010] Furthermore, the adjustment assembly includes an annular seat mounted on an adapter seat, a threaded sleeve threadedly connected to the periphery of the annular seat, a hexagonal block provided on the periphery of the threaded sleeve, a crossbar mounted at the bottom end of the threaded sleeve, one end of the pull wire passing over the crossbar and back through the annular seat, and one end of the pull wire being connected to the adapter seat.

[0011] Furthermore, the pull rod is rotatably connected to the adapter and the double rocker arm via a hinge.

[0012] Furthermore, the dual rocker arms pass through the support plate via hinges and are rotatably connected to a pair of rotating blocks.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The rotating block presses against the moving block, and the slider on the moving block presses against the spring and moves within the groove. The moving block, located at one end of the guide groove, drives the sealing plug to move into the guide groove. At this time, the lubricating oil in the guide groove flows outward along the gap between the moving block and the support plate and flows onto the rotating block, providing timely lubrication to the rotating block, preventing rust from forming on the rotating block, and extending the maintenance cycle of the device.

[0015] One end of the pull wire is passed over the crossbar and back to the ring seat. Rotating the hexagonal block on the threaded sleeve causes the crossbar to move the pull wire downwards. At the same time, the pull wires intertwine, shortening the distance between them, making it easier to adjust the tension of the pull wires and facilitating daily maintenance.
