[0035] Please refer to Figures 2-3 The lubricating assembly comprises a storage chamber 21, a communication hole 22 and a lubricating ball 23, the inside of the main shaft 1 is equidistantly provided with the storage chamber 21, the storage chamber 21 corresponds to the limit sliding groove 3, the communication hole 22 is equidistantly formed between the storage chamber 21 and the limit sliding groove 3, and the inside of each communication hole 22 is slidably connected with the lubricating ball 23; a plurality of the lubricating balls 23 are in contact with the corresponding limit sliding strips 5, the outer wall of the main shaft 1 is equidistantly provided with an oil injection hole 10, the oil injection hole 10 is in communication with the inside of the storage chamber 21, and the inside of the storage chamber 21 stores lubricating oil;

[0036] It should be noted that the storage chamber 21 formed in the inside of the main shaft 1 stores lubricating oil, and the storage chamber 21 corresponds to the limit sliding groove 3;

[0037] The storage chamber 21 and the limit sliding groove 3 are connected through the equidistantly formed communication hole 22, and each communication hole 22 is slidably connected with a lubricating ball 23;

[0038] When the secondary shaft 4 slides in the main shaft 1, the limit sliding strip 5 will extrude the corresponding lubricating ball 23, so that the lubricating ball 23 evenly applies the lubricating oil in the storage chamber 21 to the surface of the limit sliding strip 5 and the sliding groove, thereby effectively reducing the friction;

[0039] The lubricating oil can be supplemented through the oil injection hole 10 formed in the outer wall of the main shaft 1, so as to ensure the durability of the lubricating effect.

[0040] The working principle of the adjustable output shaft is as follows:

[0041] Sliding connection mechanism:

[0042] The connecting hole 2 opened in the main shaft 1 is designed with equidistant limiting sliding grooves 3 matched with limiting sliding strips 5 on the outer wall of the auxiliary shaft 4; this design ensures that the auxiliary shaft 4 can stably and smoothly slide in the main shaft 1 while maintaining a certain centering property;

[0043] Lubricating system:

[0044] The storage chamber 21 opened in the main shaft 1 stores lubricating oil, and the storage chamber 21 corresponds to the limiting sliding groove 3;

[0046] When the auxiliary shaft 4 slides in the main shaft 1, the limiting sliding strip 5 will extrude the corresponding lubricating ball 23, so that the lubricating ball 23 evenly applies the lubricating oil in the storage chamber 21 to the surface of the limiting sliding strip 5 and the sliding groove, thereby effectively reducing the friction;

[0047] The lubricating oil can be supplemented through the oil injection hole 10 opened on the outer wall of the main shaft 1 to ensure the durability of the lubricating effect;

[0048] Air pressure adjustment and sealing:

[0050] The air pressure of the air bag 7 is set at 5 cm of water column, which can ensure good sealing effect and avoid increasing additional friction and wear due to high air pressure;

[0051] When the main shaft 1 and the auxiliary shaft 4 move relatively, the air bag 7 and the hollow connecting ring 6 are not affected and maintain a stable sealing state;

[0052] Cleaning and maintenance:

[0053] When the connecting hole 2 and the limiting sliding groove 3 inside the main shaft 1 need to be cleaned, the threaded hole 8 of the hollow connecting ring 6 can be docked through the inflating device, and the air bag 7 is inflated through the one-way valve 9 to make the air bag 7 expand;

[0054] Subsequently, the threaded top rod is inserted into the avoidance hole 11 at the end of the main shaft 1 away from the auxiliary shaft 4, and the top rod is rotated to push the hollow connecting ring 6 and the air bag 7 inside to slide along the main shaft 1;

[0055] The expansion and sliding of the air bag 7 can push the lubricating oil inside the connecting hole 2 and the limiting sliding groove 3 out of the main shaft 1, so as to clean the inside of the main shaft 1;
