During adjustment, the knob 615 is moved axially to force the rubber ring 616 to be compressed, at this time, the rotating shaft 613 drives the adjusting plate 614 to separate from the positioning groove 6121 and the adjusting groove 6112, then the armrest 4 is moved to a required height, the knob 615 is rotated again, the adjusting plate 614 is rotated to be parallel to the adjusting groove 6112, finally the knob 615 is released and the sleeve 612 is slightly moved, the rubber ring 616 forces the adjusting plate 614 to slide and be inserted into the positioning groove 6121 and the adjusting groove 6112 which are butted under the action of self pre-pressure, and the operation is simple and rapid.

Referring to fig. 3, the sleeve 612 has boss holes 6123 on the top surface thereof, and the armrest 4 has a plurality of locking holes 41 formed in the bottom thereof along the length of the armrest 4. The lock 63 includes a compression spring 631 fixed to the bottom wall of the boss hole 6123, and a boss block 632 fixed to the compression spring 631. When locking, the pressure spring 631 is in an original state, the end of the boss block 632 is inserted into the locking hole 41, and the guide surface 633 abuts against the inner wall of the locking hole 41. When the armrest 4 is adjusted, the boss block 632 is separated from the locking hole 41 under the guiding action of the guiding surface 633, when the armrest 4 is moved to a required position, the boss hole 6123 is butted with the corresponding locking hole 41, and the pressure spring 631 is forced to enable the end of the boss block 632 to be inserted into the locking hole 41 under the action of self pre-pressure; at this time, the boss block 632 interferes with the boss hole 6123 to prevent the boss block 632 from easily separating from the boss hole 6123.

Referring to fig. 4, the telescopic rod 71 includes a fixed seat 711 fixed to the seat frame 2, a guide bearing 712 penetrating and fixed to the fixed seat 711, and a sliding rod 713 slidably inserted into the guide bearing 712. The sliding rod 713 and the fixed seat 711 form a structure convenient to slide, and then the guide bearing 712 and the sliding rod 713 form a telescopic structure, so that the sliding rod 713 slides smoothly and the foot rest 5 is convenient to move.

In addition, the foot rest 5 comprises a cushion body 51 and three fastening pieces 52 arranged on the cushion body 51, two cushion strips 53 are arranged on the rotating rod 73, strip-shaped grooves 54 arranged in a straight line are formed in the cushion strips 53, and the length direction of the strip-shaped grooves 54 is perpendicular to the axial direction of the rotating rod 73. The fastener 52 is a bolt slidably engaged in the groove 54 and a nut threadedly engaged on the bolt and abutting the surface of the groove 54. The cushion body 51 is connected with the rotating rod 73 through the fastener 52 and the cushion strip 53, so that the cushion body 51 can be conveniently assembled and disassembled.

Meanwhile, the stopper rod 72 is composed of a magnet, and the fastening member 52 is composed of a ferromagnetic material. The backing strip 53 abuts against the surface of the limiting rod 72, and one of the fasteners 52 abuts against the peripheral wall of the limiting rod 72 and is magnetically attracted to the limiting rod 72. The foot rest 5 is prevented from being easily turned over in the use and storage states by the mutually attracting limiting rod 72 and the fastening member 52.

The implementation principle of the embodiment is as follows: the armrest 4 is lifted through the lifting rod 61, so that the elbow joint of a user is in contact with the armrest 4, then the armrest 4 is slid and locked through the locking piece 63, so that the arm of the user can be attached to the armrest 4, the elbow joint of the keyboard mouse operated by the user for a long time is 90 degrees, and therefore the phenomenon that the shoulder and the wrist slide and humpback due to long-time fatigue are caused due to the fact that the shoulder and the wrist are in a sitting posture for a long time can be well avoided. In addition, when the user needs to support the legs, the foot supports 5 are firstly pulled out relative to the seat frame 2, the foot supports 5 are turned over to the upper side of the limiting rod 72, and then the telescopic rods 71 are adjusted, so that the foot supports 5 can support the thighs, the calves or the feet of the user, the calves and the legs are prevented from being stiff in a long-term sitting posture, the legs and the feet are prevented from being tingled, the support for the calves or the feet of the user in a lying state is facilitated, and the comfort is improved.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
