When the lead screw 105 rotates, the moving slide block 106 moves on the outer surface of the lead screw 105. When the moving slide block 106 moves, it drives the connecting rod 102 to move inside the main handlebar 101, facilitating the telescopic adjustment operation. And after the telescopic adjustment, the fixing bolt 104 is rotated to fix the connecting rod 102 and the main handlebar 101. The main body 100 of the telescopic structure of the rotating handlebar is further provided with:

[0025] An oil injection and lubrication mechanism, and the oil injection and lubrication mechanism includes a penetration component provided on one side of the bottom end of the main handlebar 101.

[0026] In order to facilitate the embedding of the oil injection pipe into the internal oil injection operation through the penetration component, in this embodiment, preferably, the penetration component includes a penetration hole 1061 opened at the bottom end of one side of the main handlebar 101. The penetration hole 1061 and the main handlebar 101 are of an integral structure, and the oil injection pipe can penetrate through the penetration hole 1061 and extend into the interior to inject oil into the interior of the oil injection port 1063.

[0027] In order to facilitate filling the annular oil passage 1064 with oil through the oil inlet component, in this embodiment, preferably, the oil inlet component includes a fixing ring 1062 fixedly installed at the bottom edge of the moving slide block 106 by screws. An annular oil passage 1064 is opened inside the fixing ring 1062. An oil injection port 1063 is opened on one side of the outer surface of the fixing ring 1062. The annular oil passage 1064 can be filled with oil through the oil injection port 1063, facilitating oil injection and lubrication. And the oil injection port 1063, the annular oil passage 1064 and the fixing ring 1062 are of an integral structure, facilitating oil injection and lubrication treatment.

The surface of the infiltration holes 1065 is provided with the oil injection sponge 1066 on the inner surface of the fixed ring 1062, and the inner surface of the oil injection sponge 1066 contacts the outer surface of the lead screw 105. When the lead screw 105 rotates, it squeezes the oil injection sponge 1066, and the lubricating oil inside flows onto the outer surface of the lead screw 105 for lubrication treatment, facilitating lubricated telescopic adjustment.

[0029] A support sliding mechanism, and this support sliding mechanism includes a support sliding assembly provided at the connection between the end of the auxiliary handle rod 103 and the main handle rod 101. When the rotary handle telescopic structure main body 100 adjusts the telescopic adjustment of the rotary handle, the support sliding mechanism can stably support the main handle rod 101 and the auxiliary handle rod 103. After the telescopic adjustment and when rotating and bearing force, it is more stable, not easily causing the rotary handle to shake unstably during use, and improving the support stability of the rotary handle telescopic structure main body 100 for the telescopic adjustment of the rotary handle.

[0030] In order to facilitate the stable telescopic adjustment of the main handle rod 101 and the auxiliary handle rod 103 through the support sliding assembly, in this embodiment, preferably, the support sliding assembly includes four support sliding grooves 1032 formed at the edge of the main handle rod 101. A support sliding rod 1031 is provided inside the support sliding grooves 1032. The top end of the support sliding rod 1031 is fixed to the bottom end of the auxiliary handle rod 103 by screws. When the main handle rod 101 and the auxiliary handle rod 103 are telescopically adjusted, the support sliding rod 1031 can be driven to slide inside the support sliding grooves 1032 for support, facilitating more stable telescopic adjustment of the rotary handle.

[0031] The working principle and usage process of the present utility model: For the telescopic structure of this kind of rotary handle, when in use, a wrench can be clamped on the outer surface of the rotating body 107 to drive the lead screw 105 to rotate. When the lead screw 105 rotates, the moving slide block 106 moves on the outer surface of the lead screw 105. When the moving slide block 106 moves, it drives the connecting rod 102 to move inside the main handle rod 101, thereby adjusting the auxiliary handle rod 103. After the adjustment, the fixing bolt 104 is rotated to fix the connecting rod 102 and the main handle rod 101, thereby achieving the telescopic adjustment of the rotary handle through the rotary handle telescopic structure main body 100;

[0032] Then, when the rotating handlebar telescopic structure main body 100 adjusts the telescopic length of the rotating handlebar, and the connecting rod 102 slides inside the main handlebar 101 to drive the auxiliary handlebar 103 to slide, the end of the auxiliary handlebar 103 drives the support slide bar 1031 to slide inside the support chute 1032 to support the sliding of the auxiliary handlebar 103 and the connecting rod 102. This facilitates stable support for the telescopic operation, and when rotating and bearing force after the telescopic adjustment, it is more stable and not easily causes shaking and instability during the use of the rotating handlebar, improving the support stability of the rotating handlebar telescopic structure main body 100 for the telescopic adjustment of the rotating handlebar;

[0033] Finally, when the rotating handlebar telescopic structure main body 100 is installed and before the telescopic adjustment, the connecting rod 102 can be adjusted to the lowest end. The oil injection pipe is inserted into the oil injection port 1063 through the inside of the through hole 1061 and injects oil into the inside of the annular oil passage 1064. After injecting oil into the inside of the annular oil passage 1064, it seeps into the inside of the oil injection sponge 1066 through the seepage hole 1065. Therefore, when the screw rod 105 rotates to move the moving slide 106 on the outer surface of the screw rod 105, at this time, the oil injection sponge 1066 presses tightly on the outer surface of the screw rod 105 to inject oil onto the outer surface of the screw rod 105, facilitating oil injection and lubrication treatment when the screw rod 105 is adjusted. During the telescopic adjustment, it is not easy to cause large friction damage between the screw rod 105 and the moving slide 106, extending the service life and improving the convenience of oil injection and lubrication when the rotating handlebar telescopic structure main body 100 adjusts the telescopic length of the rotating handlebar.
