Next, a second embodiment of the supporting device 1000 of the present application will be described with reference to fig. 7 and 8 (some elements are omitted for convenience of description, and only a part of the upright post 2 and the stopper module 5 are shown). The second embodiment is different from the first embodiment in the design of the stopping module 5, and only the differences will be described below, and the same technical contents will not be described herein again.

The operation of the stopping module 5 between the locking state and the releasing state in the second embodiment of the supporting device 1000 of the present application is described below. Please refer to fig. 11, which shows that the stopping module 5 is kept in the stopping state due to the elastic force provided by the elastic member 55, at this time, the first pressing block 53 is pressed and stopped at the first abutting surface 211, and abuts against one of the limiting surfaces 5213 but not against one of the stopping surfaces 5221, and the second pressing block 54 is pressed and stopped at the second abutting surface 212, and abuts against the other one of the limiting surfaces 5213 but not against the other one of the stopping surfaces 5221, so that the pulley 3 cannot slide relative to the upright post 2. Referring to fig. 12, when an external force F is applied to the button 52, so that the button 52 slides along the second axis X2 toward the fixing base 51, at this time, since the width W3 of the first sliding portion 532 and the second sliding portion 542 is smaller than the width W2 of each of the sliders 523, and the first body portion 531 and the second body portion 541 are guided by the limiting surface 5213, the first pressing block 53 and the second pressing block 54 approach each other along the third axis X3 until the first body portion 531 abuts against one of the stopping surfaces 5221 and the second body portion 541 abuts against the other stopping surface 5221, at this time, the first pressing block 53 disengages from the first abutting surface 211, and the second pressing block 54 disengages from the second abutting surface 212, and the elastic member 55 is compressed to gradually increase the elastic force, so that the stopping module 5 is transformed from the vertical stopping state to the releasing state, and the pulley 3 and the stopping module 5 can slide relative to the pillar 2. If the stopping module 5 is to be changed from the releasing state to the locking state again, only the external force F is removed, and at this time, the button 52 will be separated from the fixing seat 51 through the resilience of the elastic member 55, the first pressing block 53 and the second pressing block 54 are respectively guided by the limiting surface 5213 to be separated from the stopping surface 5221, and are separated from each other gradually along the third axis X3 until the first pressing block 53 is pressed and locked on the first abutting surface 211, and the second pressing block 54 is pressed and locked on the second abutting surface 212, in this process, the elastic force of the elastic member 55 will be gradually reduced.

The second clip 621 has a second clip block 6211 and a second protruding column 6212, the second clip block 6211 is substantially arcuate, the second protruding column 6212 is substantially cylindrical and formed on the second clip block 6211, and the first protruding column 6112 and the second protruding column 6212 are correspondingly formed on the adjacent sides of the first clip block 6111 and the second clip block 6211 respectively in a manner corresponding to each other. The second pivot hole 623 is surrounded by the second ring 622 and correspondingly communicates with the first pivot hole 613. The second handle member 624 extends outwardly from the second ring 622 along the second axis X2 and through the opening 23 in a direction opposite to the direction in which the second clip body 621 extends and corresponds to the first handle member 614.

The first tightening block 63 is substantially a square body and is fixedly disposed on a side of the first clamping block 6111 opposite to the side where the first protruding pillar 6112 is disposed, that is, the first tightening block 63 and the first protruding pillar 6112 extend in opposite directions. The second clamping block 64 is substantially square and fixedly disposed on the opposite side of the second clamping block 6211 to the side on which the second protruding pillar 6212 is disposed, that is, the second clamping block 64 and the second protruding pillar 6212 extend in opposite directions, and the second clamping block 64 and the first clamping block 63 are respectively and fixedly disposed on the far side of the first clamping block 6111 and the far side of the second clamping block 6211. The pivot 65 passes through the first pivot hole 613 and the second pivot hole 623, so that the first clamping arm 61 and the second clamping arm 62 are pivoted with each other and can pivot with the pivot 65 as a core. Two ends of the elastic element 66 are respectively sleeved on the first protruding pillar 6112 and the second protruding pillar 6212, i.e. respectively abut against the first clamping block 6111 and the second clamping block 6211, so as to constantly provide an elastic force. In the present embodiment, the elastic member 66 is a compression spring, but not limited thereto.

The operation of the stopping module 6 between the locking state and the releasing state in the third embodiment of the supporting device 1000 of the present application is described below. Please refer to fig. 16, which shows that the stopping module 6 is kept in the locking state by the elastic force provided by the elastic member 66, at this time, the distance D1 between the center of the end of the first handle 614 and the center of the end of the second handle 624 is the largest, and the distance between the first clamp body 611 and the second clamp body 621 is also the largest by the connection belt, the first clamping block 63 is clamped and locked on the first abutting surface 211, and the second clamping block 64 is clamped and locked on the second abutting surface 212, whereby the pulley 3 cannot slide relative to the upright post 2. Referring to fig. 17, an external force F is applied to the first handle 614 and the second handle 624, such that the distance between the center of the end of the first handle 614 and the center of the end of the second handle 624 gradually decreases (for example, decreases to a distance D2), at this time, the distance between the first clamp 611 and the second clamp 621 also gradually decreases, the first clamp block 6111 and the second clamp block 6211 jointly compress the elastic member 66 to gradually increase the elastic force, the first clamping block 63 and the second clamping block 64 are both separated from the first abutting surface 211 and the second abutting surface 212, respectively, and the stop module 6 is switched from the locking state to the releasing state, such that the pulley 3 and the stop module 6 can slide relative to the upright post 2. If the stopping module 6 is to be changed from the releasing state to the locking state again, the external force F is removed, and the first clamp 611 and the second clamp 621 are separated from each other by the resilience of the elastic member 66 until the first clamping block 63 and the second clamping block 64 are respectively clamped and locked on the first abutting surface 211 and the second abutting surface 212, and the distance between the first handle 614 and the second handle 624 is gradually increased, and the elastic force of the elastic member 66 is gradually decreased in the process.

In summary, the supporting device of the present application, through the design of the stopping module, when the supporting device does not carry the display, the user can fix the position of the pulley on the upright post at any time by using the stopping module, so as to avoid the recoil of the constant force spring, reduce the frightened situation of the user, and improve the operation experience.
