In this embodiment, the second elastic body 73 is a torsion spring.

The actuation of the lever module 7 in the pushing state ( FIG. 5 ) and the releasing state ( FIG. 6 ) will be further described below. Please refer to Fig. 5, when the lever module 7 is in the pushing state (the lever block 72 is horizontal), the stop block 714 limits the lever block 65, that is, it is pushed against the rear side relatively close to the car body 31, at this time The first elastic body 66 is simultaneously compressed by the positioning tenon 63 and the stop plate 64, the cup body 61 is adjacent to the stop plate 64, and the positioning tenon 63 is accommodated in one of the positioning holes 24, whereby the pulley 3, stop The moving module 6 and the lever module 7 do not move relative to the upright column 2 . At this time, the lever block 72 partially extends outward from the operation opening 381 and is roughly located in the center of the operation opening 381 , away from the bottom end 3811 of the operation opening 381 . If it is to change from the pushing state to the release state, then continue to apply an external force to the lever block 72 (to make the lever block 72 tilt), so that the pivot seat 71 can rotate relative to the tackle 3 with the rod 51 as the axis, and stop The block 714 gradually releases the shifting block 65 along the second axis X2 (the shifting block 65 is relatively far away from the rear side of the vehicle body 31), the first elastic body 66 gradually rebounds (that is, the first elastic force gradually decreases), and the cup body 61 and The shifting block 65 moves along the second axis X2 in the limiting groove 35, so that the cup body 61 is gradually moved away from the stop plate 64, the positioning tenon 63 is disengaged from one of the positioning holes 24, and the shifting lever module 7 enters the release state. The pulley 3 , the stop module 6 and the lever module 7 can slide relative to the upright column 2 , that is, the up and down position of the display 3000 can be adjusted.

Further, as shown in FIG. 6, at this time, the lever block 72 is adjacent to the bottom end 3811 of the operating port 381, and one end of the second elastic body 73 is pressed by the wing plate 712, so the second elastic force gradually becomes Large, when the external force is removed, the second elastic body 73 tends to rebound (that is, the second elastic force gradually becomes smaller) to reset the pivot seat 71, the stopper 714 pushes the dial 65 along the second axis X2, and the cup body 61 moves toward the stop plate 64 and compresses the first elastic body 66 at the same time (that is, the first elastic force gradually increases), and the lever module 7 returns to the push-out state. At this time, the positioning tenon 63 is accommodated in the positioning hole 24 One of them, in other words, in the case of no external force is applied, it tends to remain in the pushing state, and the pulley 3 , the stopper module 6 and the lever module 7 are relatively stationary to the upright column 2 .

In addition, in this embodiment, the pulling force of the elastic member 4 is slightly less than the total gravity of the display 3000, the pulley 3, the shaft unit 5, the stop module 6, the lever module 7 and the load-carrying cantilever module 2000, so when positioning When the tenon 63 is not aligned with one of the positioning holes 24 (between the two positioning holes 24), in the process of changing from the releasing state to the pushing state, the pulley 3 will automatically go down (due to the total gravity Slightly greater than the pulling force) to move slightly, so that the positioning tenon 63 is aligned with the positioning hole 24 that is the nearest and located below, and then enters the push-off state smoothly; on the contrary, if the pulling force of the elastic member 4 is slightly greater than the display 3000, the pulley 3, and the shaft The total weight of the unit 5, the stop module 6, the lever module 7 and the load-carrying cantilever module 2000, when the positioning tenon 63 is not aligned with one of the positioning holes 24, during the transition from the release state to the push state, Tackle 3 can move upwards (because total gravity is slightly less than pulling force) slightly automatically, makes positioning tenon 63 aim at the positioning hole 24 that is closest and is positioned at top, then still can enter push-off state smoothly.

To sum up, through the design of the lever module 7 in the supporting device 1000 of the present application to keep the push-up state, when the user removes the display 3000 from the supporting cantilever module 2000, the upward pulling force provided by the elastic member 4 will suddenly be greater than The total weight of the pulley 3, the shaft unit 5, the stop module 6, the lever module 7, and the load-carrying cantilever module 2000, but because the positioning tenon 63 is accommodated in the positioning hole 24, the movement of the pulley 3 along the first axis X1 is limited. Moving, that is, the block 3 does not move relative to the upright column 2 without backlash (upstroke), which can prevent the user from being impacted by the load-bearing cantilever module 2000, and in this state, if the block 3 is to be moved, or hang When the display 3000 needs to be lifted and lowered, as long as the lever block 72 is pressed to make the positioning tenon 63 break away from the positioning hole 24 to release the push state, it can be lifted normally, and once the finger leaves the lever block 72, it will automatically Rebound to push-up state. Even in the process of automatically rebounding to the pushing state, when the positioning tenon 63 is not aligned with the positioning hole 24 (for example, the positioning tenon 63 is pressed between any two positioning holes 24), the pull-up force of the elastic member 4 or The total gravity of the display 3000, the trolley 3, the shaft unit 5, the stopper module 6, the lever module 7 and the load-carrying cantilever module 2000, and the first elastic force of the first elastic body 66 can allow the positioning tenon 63 to be automatically inserted into the next sequence. In the positioning hole 24 of the bit. The supporting device 1000 of the present application is convenient to use as a whole, has a good experience, and has high safety.

The support device of claim 8, wherein the lever module comprises a pivot base and a lever block, the pivot base has a seat plate, two wing plates, a top plate and a stop block, the wing plates are respectively formed by extending vertically from two opposite sides of the seat plate, the top plate is formed by extending vertically from the top side of the seat plate and is fixedly connected between the wing plates, the stop block is formed by extending outwards from the top plate and is correspondingly abutted against the lever block, the lever block is fixedly connected to the seat plate and is partially extended outwards from the opening, the pivot base further has two through holes, each through hole is respectively formed by penetrating through the wing plates along the third axis, and the rod is arranged through the through holes, thereby the pivot base can rotate relative to the pulley by taking the rod as an axis.

10. The support device of claim 9, wherein the first elastic body is a compression spring, the second elastic body is a torsion spring, the stop block limits the shift block when the shift lever module is in the pushing state, the stop block releases the shift block along the second axis when an external force is applied to the shift lever block to enable the pivot block to rotate relative to the pulley with the rod as an axis and enable the shift lever module to enter the releasing state, and the second elastic body resets the pivot block when the external force is removed, and the shift lever module returns to the pushing state.
