The first plug-in mechanism 5 includes a first plug-in outer tube 501 arranged on the left frame 1 and the right frame 2, a first plug-in inner tube 502 arranged below the elbow support 401, and a first locking wrench 503. The first plug-in inner tube 502 is plugged and connected to the first plug-in outer tube 501. The first locking wrench 503 is arranged on the first plug-in outer tube 501 and is used to switch the first plug-in inner tube 502 between a locked state and an active state. In this embodiment, the elbow support assembly 4 is detachably connected to the left frame 1 and the right frame 2 through the first plug-in mechanism 5, and the elbow support 401 is plug-connected to the first plug-in outer tube 501 through the first plug-in inner tube 502. It has the advantages of simple structure and convenient and quick installation and disassembly. When it is necessary to adjust the height of the elbow support assembly 4, the first plug-in inner tube 502 can be moved axially relative to the first plug-in outer tube 501 by opening the first locking wrench 503. After moving to the target height, the first locking wrench 503 can be closed to achieve the locking positioning of the first plug-in inner tube 502 and the first plug-in outer tube 501. The operation is simple and convenient, and can meet the usage needs of users of different heights.

[0024] Preferably, the elbow support 401 includes a vertical connection part 4011 and a horizontal connection part 4012, a second locking wrench 404 is provided on the horizontal connection part 4012, a first positioning pin 405 is provided on the vertical connection part 4011, the vertical connection part 4011 is plug-connected with the first plug-in inner tube 502, the first positioning pin 405 passes through the vertical connection part 4011 and is arranged with the first plug-in inner tube 502, the handle tube 402 includes a vertical extension part 4021 and a horizontal extension part 4022, the horizontal extension part 4022 is plug-connected in the horizontal connection part 4012, the second locking wrench 404 is used to convert the handle tube 402 between a locked state and an active state, and the elbow support 403 is fixedly provided on the horizontal connection part 4012. In this embodiment, the handle tube 402 is plugged into the horizontal connecting part 4012 through the horizontal extension part 4022, so that the handle tube 402 is installed on the elbow bracket 401. When the extended length of the handle tube 402 needs to be adjusted, the second locking wrench 404 is opened to make the horizontal extension part 4022 move axially relative to the horizontal connecting part 4012. After moving to the target length, the second locking wrench 404 is closed to realize the locking positioning of the horizontal extension part 4022 in the horizontal connecting part 4012, which has high flexibility in use.

[0025] like Figure 4As shown, preferably, the handrail frame 3 is connected to the left frame 1 and the right frame 2 through a second plug-in mechanism 6, and the second plug-in mechanism 6 includes a second plug-in outer tube 601 arranged on the left frame 1 and the right frame 2, a second plug-in inner tube 602 arranged below the handrail frame 3, and a second positioning pin 603. A through hole 6011 is provided on the second plug-in outer tube 601, and a plurality of groups of positioning holes 6021 arranged in a vertical direction are provided on the second plug-in inner tube 602. The second positioning pin 603 passes through the through hole 6011 and the positioning hole 6021 to adjust the height of the handrail frame 3. In this embodiment, when the height of the handrail frame 3 needs to be adjusted, the second positioning pin 603 is first pulled out. At this time, the second plug-in inner tube 602 can move back and forth relative to the second plug-in outer tube 601. After adjusting to the appropriate height, the second positioning pin 603 is passed through the through hole 6011 and the positioning hole 6021 to lock the second plug-in inner tube 602 in place in the second plug-in outer tube 601.

[0026] Preferably, the first positioning pin 405 and the second positioning pin 603 have the same structure, both including a pipe clamp portion 6031 for engaging the outer wall of the tube and a pin portion 6032 for passing through the hole. The first positioning pin 405 and the second positioning pin 603 are respectively clamped to the outer wall of the vertical connection portion 4011 and the second plug-in outer tube 601 through the pipe clamp portion 6031. The connection stability is good and can effectively prevent the positioning pins from falling off accidentally.
