[0008] By adopting the above technical solution, when the height of the chair body needs to be adjusted, the user directly uses both hands to loosen the restraint on the adjustment rod through the limiting mechanisms located on both sides of the chair body, and then lifts or presses the chair body to make the adjustment rod slide on the fixed plate until the height of the chair body is appropriate, and then limits the position of the adjustment rod on the fixed plate through the limiting mechanism, thereby completing the height adjustment of the bathroom chair; compared with the existing bathroom chair footrest, the bathroom chair is much more convenient to use.

[0009] and a control button to move the adjusting member so that the adjusting member can be adjusted relative to the adjustment member so that the adjusting member can be adjusted relative to the adjustment member.

[0010] By adopting the above technical solution, the first driving component drives the driving block to slide vertically upward, so that the driving block leaves the plug-in rod, and the plug-in rod is elastically acted upon by the first elastic member to leave the limiting hole, thereby releasing the restraint on the adjustment rod and adjusting the height of the chair body; the first driving component drives the driving block to slide vertically downward, and through the guiding action of the guide surface, drives the plug-in rod to be reinserted into the corresponding limiting hole, thereby limiting the position between the adjustment rod and the fixed plate.

[0011] Preferably, the first driving assembly includes a pull rod, a second elastic member and a pull button, the pull rod extends in a vertical direction and is installed in the adjusting rod, and the pull button is slidably installed in the vertical direction on the adjusting rod; one end of the pull rod is connected to the driving block, and one end of the pull button is connected to the other end of the pull rod, and the pull button extends out of the adjusting rod away from one end of the pull rod; the second elastic member is sleeved on the pull rod, and the two ends of the second elastic member are respectively installed in the driving block and the adjusting rod; the elastic force of the second elastic member is greater than the elastic force of the first elastic member.

[0012] By adopting the above technical solution, the user can directly pull the pull buttons located on both sides of the chair body vertically upward with both hands, thereby pulling the pull rod, and then driving the driving block to move vertically upward; when the pull button is released, the elastic action of the second elastic member causes the driving block to slide vertically downward. Since the elastic force of the second elastic member is greater than the elastic force of the first elastic member, the guiding effect of the guide surface is smoothly achieved, driving the connecting rod to be reinserted into the corresponding limiting hole; this structure is easy to operate.

[0013] Preferably, one end of the pull button located outside the adjusting rod is bent in the horizontal direction.

[0014] By adopting the above technical solution, the force-bearing area is increased, making it more convenient for users to lift the trigger.

The limit mechanisms then restrict the position of the adjustment rods on the fixed plate, thus completing the height adjustment of the bathroom chair. Compared with existing bathroom chair tripods, this greatly improves the convenience of use of bathroom chairs.

[0029] 2. The user simply pulls the levers located on both sides of the chair body vertically upward with both hands, thereby pulling the pull rod, thereby driving the driving block to move vertically upward; when the levers are released, the elastic action of the second elastic member causes the driving block to slide vertically downward. Since the elastic force of the second elastic member is greater than the elastic force of the first elastic member, the guiding effect of the guide surface is smoothly achieved, driving the plug rod to be reinserted into the corresponding limit hole; this structure is easy to operate;

[0031] 4. When the user is in an upright position, they can directly press or lift the free end of the handle, causing it to swing with the fulcrum arc block as the fulcrum. By driving the rod to slide in the guide groove, the pull rod is lifted, thereby pulling the pull rope. The pull rope pulls the end of the pressing swing arm extending out of the sleeve, causing the pressing swing arm to swing and press the ejector pin of the gas spring to adjust the angle of the chair body; improving the convenience of operation, without the user having to bend over to operate;

[0032] 5. The headrest can support and protect the user's head, and the height and angle of the headrest can be adjusted according to the user's needs through the adjustment component to improve applicability. BRIEF DESCRIPTION OF THE DRAWINGS
