It should be noted that the terms "comprising" and "having" and any variations thereof in the embodiments of the present application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but can optionally include steps or units that are not listed, or can optionally include other steps or components inherent to these processes, methods, products, or devices.

[0030] Specifically, the shell 100 is formed with a receiving cavity; optionally, the shell 100 in the embodiment can be a hollow cylindrical structure. The outer end of the shell 100 is provided with a sleeve 110, one end of the support rod 200 is inserted into the receiving cavity, the other end (the end close to the sleeve 110) is exposed outside the receiving cavity, and the support rod 200 can slide along the receiving cavity (in the direction of the arrow in the figure) to change the support distance of the support device (the distance from one end to the other end of the support device as a whole). Figure 3

[0031] Among them, the stop device 300 is connected with one end of the support rod 200 inserted into the receiving cavity. The control device 400 is connected with the end of the support rod 200 exposed outside the receiving cavity, and the control device 400 is used to control the connection state of the stop device 300 and the inner wall of the shell 100, thereby controlling the stop position of the support rod 200 relative to the shell 100, and thereby realizing the support of different positions (lengths) of the support device.

[0032] Among them, please continue to refer to Figure 2 and Figure 3 ​The stop device 300 comprises a stop sleeve 310, a steel ball 320 and a steel ball baffle 330. The outer periphery of the stop sleeve 310 is provided with a stop groove 311 with a plurality of annular inclined surfaces. The steel ball 320 is arranged in the stop groove 311 and abuts against the inner side wall of the shell 100. When the stop sleeve 310 moves to the right, the steel ball 320 cooperates with the stop groove 311 with inclined surfaces and the inner side wall of the shell 100 to fix the position. The steel ball baffle 330 is used to block the steel ball 320 from the stop sleeve 310 towards one end of the support rod 200.

[0033] The control device 400 comprises a connecting rod 410, an operation button 420 and a self-locking ejector pin 430. The connecting rod 410 is arranged in the support rod 200. One end of the connecting rod 410 abuts against the steel ball baffle 330 and the other end abuts against the self-locking ejector pin 430. The self-locking ejector pin 430 is connected with the operation button 420. The connecting rod 410 is used to drive the steel ball baffle 330 to move under the driving of the operation button 420, thereby pushing the steel ball 320 to move and realize unlocking.

[0034] Optionally, please continue to refer to Figure 2 The steel ball 320 can be a plurality of annularly distributed steel balls in the plurality of annular stop grooves 311 on the outer periphery of the stop sleeve 310. Optionally, the stop device 300 further comprises a plurality of steel ball spacing rings 340. The steel ball spacing rings 340 are arranged between different annular steel balls. On the one hand, the steel ball spacing rings 340 can separate the adjacent annular steel balls 320. On the other hand, the steel ball spacing rings 340 can transfer the pushing force to the steel balls 320 in different annular positions during the unlocking process of the steel ball baffle 330 pushing the steel balls 320 to move to the right of the arrow in the figure, so that the steel balls 320 in different annular positions can move approximately synchronously, thereby realizing unlocking. Figure 3

[0035] Please continue to refer to Figure 3 The operation button 420 and the self-locking ejector pin 430 are in contact through a supporting inclined surface 421. During the pressing process of the operation button 420, the supporting inclined surface 421 supports the self-locking ejector pin 430, thereby making the self-locking ejector pin 430 and the connecting rod 410 move to the right of the arrow in the figure.

The connecting piece 360 is connected with the connecting rod 410. The two ends of the spring 350 support the connecting piece 360 and the steel ball baffle 330, respectively. The two ends of the connecting sleeve 370 are threadedly connected with the support rod 200 and the stop sleeve 310, respectively. ​

[0037] Please refer to Figure 2 and Figure 4 , Figure 4 is Figure 2 The structural schematic diagram of the steel ball baffle plate in the embodiment, the steel ball baffle plate 330 includes a support 331, a connecting column 332, and a baffle ring 333. The connecting column 332 can be multiple (four in the embodiment, and the specific number is not limited). The connecting column 332 is inserted into the outer ring of the support 331. The outer end of the connecting column 332 is connected with the baffle ring 333. The baffle ring 333 is used for resisting and pushing the steel ball 320 to move.

[0038] The control device 400 further includes a control end cover 440. Please refer to Figure 2 , Figure 3 and Figure 5 , Figure 5 is Figure 2 The structural schematic diagram of the control end cover in the embodiment. The control end cover 440 is connected with the support rod 200 through threads. The control end cover 440 is provided with a containing hole 441. The operation button 420 is inserted into the containing hole 441. The control end cover 440 is provided with an air hole 442 which is in communication with the containing hole 441. The air hole 442 is used for being connected with an external inflation device (not shown in the figure, and the external inflation device can be a structure such as an air pump, which is not limited here). The air hole 442 is used for being inflated to drive the operation button 420 to move along the containing hole 441. The inflation of the air hole 442 and the pressing of the operation button 420 are two ways of driving the operation button 420 to move. The advantage of the air pressure driving is that the operator can be away from the dangerous area to be supported, or when the support area is not convenient to operate, the advantage of the air pressure driving is embodied.

[0039] Please continue to refer to Figure 2 and Figure 3 The control device 400 further includes a protective sleeve 450. The protective sleeve 450 is sleeved on the end of the control end cover 440 which is away from the support rod 200.
