[0001] The utility model relates to the technical field of a tower crane cantilever mechanism, in particular to a telescopic tower crane cantilever mechanism. Background Art

[0002] The pendant is an indispensable gas supply medical equipment in the modern operating room of the hospital. It is mainly used for the terminal transfer of oxygen supply, suction, compressed air, nitrogen and other medical gases in the operating room. It is safe and reliable to control the lifting of the equipment platform by the motor. The balanced design ensures the level of the equipment platform and the safety of the equipment. The drive of the motor ensures that the equipment operates quickly and effectively.

[0003] After searching the publication (announcement) number: tower cantilever mechanism, a medical tower lifting arm is disclosed, including a mounting frame, and also including: a telescopic structure, which is arranged at the bottom end of the mounting frame; wherein the telescopic mechanism includes a first cantilever, the first cantilever is connected to the bottom end of the mounting frame, the inner side of the first cantilever is sleeved with a movable plate, the end of the movable plate is installed with a second cantilever, one of the second cantilever is installed with a long rod, one side of the first cantilever is provided with a notch, the inside of the notch is installed with a first fixed rod, the outer surface of the first fixed rod is sleeved with a reset spring and a movable latch, the bottom of the first cantilever is installed with a drive motor 1, and the output shaft of the drive motor 1 is installed with a cam. The cam squeezes the movable latch, so that the first cantilever and the second cantilever can be positioned through the cooperation between the movable latch and the movable plate, thereby facilitating the control of the length between the first cantilever and the second cantilever and reasonably allocating space.

[0004] Although the above scheme positions the first cantilever and the second cantilever by the cooperation between the movable latch and the movable plate, thereby facilitating the control of the length between the first cantilever and the second cantilever and reasonably allocating the space, it cannot achieve the angle adjustment of the mounting frame.
