the inner walls of the plurality of annular grooves are respectively provided with a plurality of oil outlet holes communicated with the main connecting block, and annular pressing blocks are arranged in the annular grooves;

a sponge and an annular grid plate are sequentially arranged between the inner surface of the annular pressing block and the inner wall of the annular groove;

the outer surface of the annular pressing block is provided with a pushing block;

and a slot hole for accommodating the push block to extend is formed in the outer wall of the annular groove.

Furthermore, a tension spring is arranged between the annular pressing block and the outer wall of the annular groove.

Furthermore, a compression spring is arranged between the two ends of the annular pressing block and the inner wall of the annular groove.

Furthermore, the push block is trapezoidal, the lower bottom of the push block is connected with the annular pressing block, and the upper bottom of the push block extends out of the outer wall of the annular groove.

Further, the slotted hole is provided with a sealing ring.

Furthermore, a soft sealing cover for covering the pushing block is arranged on the annular connecting block at the periphery of the slotted hole.

Furthermore, an oil filling hole is formed in the annular connecting block corresponding to each annular groove, and a plug cover is arranged on the oil filling hole.

Further, a first sealing ring is fixedly arranged on the oil filling hole, and a second sealing ring is fixedly arranged on the plug cover.

Further, the steering wheel is of an annular structure.

Further, the oil injection hole is provided with five.

By adopting the technical scheme, compared with the prior art, the invention has the following advantages:

1. the setting of ring channel and oil outlet can pass through the extrusion sponge when main connecting block lacks the lubrication, lets during the lubricating oil in the sponge adds main connecting block, avoids the long-time operation back of main connecting block, appears lubricated not enough and loses the unable normal operating problem of basic function, has improved the life of device to a certain extent.

2. Due to the arrangement of the oil filling hole, after lubricating oil in the sponge is used up, the lubricating oil can be conveniently and quickly added into the annular groove, and the plug cover can prevent the lubricating oil from leaking out of the annular groove.

3. The arrangement of the tension spring and the compression spring pulls or presses the annular pressing block to the outer wall of the annular groove, so that on one hand, the annular pressing block can not extrude the sponge all the time, the service life of the sponge is prolonged, and the possibility of adding lubricating oil into the main connecting block all the time can be avoided; on the other hand, the push block is tightly combined with the seal ring of the groove hole, so that the sealing performance is better.

4. The arrangement of the seal ring and the soft seal cover on the slotted hole plays a role in sealing, and lubricating oil is prevented from seeping out of the slotted hole.
