By providing the elastic portion 61, the positioning member 6 can be easily moved from one of the first position 33 and the second position 34 to the other, and can be effectively positioned at the current position, thereby improving the structural stability.

Referring to fig. 12, 14, 17 and 21, the pushing portion 21 is disposed in the second sleeve 2. The pushing portion 21 is arc-shaped and protrudes into the second sleeve 2. The size of the central angle of the pushing part 21 can be determined according to the swinging angle of the seat plate 220, so that when the seat plate 220 swings to the minimum or maximum angle, the pushing part 21 is used for pushing the positioning part 6 to change the direction and positioning. Two ends of the pushing portion 21 are provided with pushing surfaces 21a, the upper end of the positioning member 6 is protrudingly provided with a top abutting portion 63, when the seat plate 220 rotates to a first state relative to the guide rod 230, one of the pushing surfaces 21a of the pushing portion 21 can abut against one side surface 63a of the top abutting portion 63, and when the seat plate 220 rotates to a second state relative to the guide rod 230, the other pushing surface 21a of the pushing portion 21 can abut against the other side surface 63a of the top abutting portion 63, so that the positioning member 6 can be pushed to swing when the seat plate 220 rotates, and the positioning member 6 is transferred from one of the first position 33 and the second position 34 to the other. By providing the pushing surface 21a, the positioning element 6 can be pushed to switch to another position when the seat plate rotates to a maximum angle or a minimum angle relative to the guide rod 230, so that the locking directions of the ratchet 4 and the pawl 5 can be switched, thereby realizing repeated adjustment and improving the convenience of operation.

Since the pawl 5 is eccentrically disposed on the spindle 3, after the first engaging tooth 51 is engaged with the ratchet wheel 4, the ratchet wheel 4 is locked when rotating in one direction, and can rotate in the other direction, so as to achieve the purpose of being rotatable in one direction. The pawl 5 extends out of a clamping foot 53, one end of the elastic piece 7 is arranged on the positioning piece 6, and the other end is clamped on the clamping foot 53. This enables the elastic force of the elastic member 7 to act on the catch 53, thereby swinging the pawl 5. Specifically, one end of the elastic member 7 is provided with a fixing ring 71, the front end of the positioning member 6 is provided with a positioning ring 64, the fixing ring 71 is sleeved on the positioning ring 64, two elastic legs 72 extend from the other end of the elastic member 7, and the two elastic legs 72 are respectively located at two sides of the clamping leg 53 and elastically clamp the clamping leg 53. When the pawl 5 swings, the elastic foot 72 can provide an elastic force in the opposite direction to reset the pawl 5.

Since the main shaft 3 is pivotally connected to the pawl 5 and the positioning member 6 by the rotating shaft 8, the rotating shaft 8 is eccentrically disposed with respect to the main shaft 3, and the pawl 5 is provided with the first engaging tooth 51 and the second engaging tooth 52 that are engageable with the ratchet 4, when the seat plate 220 swings with respect to the guide bar 230, one of the first engaging tooth 51 and the second engaging tooth 52 of the pawl 5 is engaged with the ratchet 4. The principle of unidirectional adjustment is realized by using the ratchet 4 and the pawl 5, so that the seat plate 220 can only rotate around the main shaft 3 in one direction, and is locked in the opposite direction. In addition, the pushing portion 21 of the seat plate 220 pushes the positioning member 6 to swing, so that the locking directions of the pawl 5 and the ratchet 4 can be switched, and thus, the seat plate 220 can be opened at a certain angle in one direction relative to the guide rod 230 and can be positioned at the angle to achieve the angle adjustment between the two rods. The whole structure does not need to use conventional connecting rod linkage and positioning, does not influence the appearance of a product, and is simple; in addition, the seat plate 220 can be adjusted and locked only by rotating, and the direction can be automatically switched when the maximum angle or the minimum angle is adjusted, so that repeated adjustment is realized, and the operation is very convenient.

In summary, the operation of the folding mechanism 100 of the present invention is described in detail as follows:

as shown in fig. 15 to 18, when the seat plate 220 is in the first state, which is the folded state, relative to the guide rod 230, the seat plate 220 can be rotated clockwise, and at this time, one of the pushing surfaces 21a of the pushing portion 21 of the seat plate 220 pushes one of the side surfaces 63a of the abutting portion 63, so that the positioning element 6 swings. At this time, the elastic portion 61 of the lower end of the positioning member 6 moves from the first position 33 to the second position 34 over the rib 32. Meanwhile, the pawl 5 is driven by the elastic element 7 to swing along with the positioning element 6, so that the first engaging tooth 51 of the pawl 5 leaves the ratchet 4, and the second engaging tooth 52 is engaged with the ratchet 4. The seat plate 220 is now locked in a clockwise direction and unlocked in a counter-clockwise direction. Therefore, the seat plate 220 can rotate a certain angle in the counterclockwise direction to achieve the purpose of adjusting the position; at any angle, the seat plate 220 is locked in the clockwise direction and can rotate in the counterclockwise direction.

As shown in fig. 19 to fig. 22, when the seat plate 220 is in the second state of the fully unfolded state relative to the guide rod 230 and the seat plate 220 needs to be folded, the seat plate 220 only needs to be rotated continuously in the counterclockwise direction, and at this time, the other pushing surface 21a of the pushing portion 21 of the seat plate 220 pushes the other side surface 63a of the abutting portion 63, so that the positioning member 6 swings. At this time, the elastic portion 61 of the lower end of the positioning member 6 passes over the rib 32 from the second position 34 to the first position 33. Meanwhile, the pawl 5 is driven by the elastic element 7 to swing along with the positioning element 6, so that the second engaging tooth 52 of the pawl 5 leaves the ratchet 4, and the first engaging tooth 51 is engaged with the ratchet 4. The seat plate 220 is now locked in a counter-clockwise direction and unlocked in a clockwise direction. At this time, the seat plate 220 may be rotated in a clockwise direction to return to the first state; by repeating the above process, the seat plate 220 can be repeatedly adjusted in its relative angle with respect to the guide bar 230.

Referring to fig. 6, 23 to 25, the operation of the foldable foot support 200 of the present invention will be described in detail as follows:

when the folding foot rest 200 is in the unfolded state, the seat plate 220 is at an angle of 90 degrees with respect to the guide bar 230 and is in a horizontal state. At this time, the user can work while sitting on the seat plate 220.
