[0040] like Figure 2-4 As shown, in one embodiment of this application, the extension 14 includes: a first sliding plate 141, a first limiting plate 142, and a second limiting plate 143.

[0041] The first skateboard 141 is slidably mounted on the backrest 12.

[0042] The first limiting plate 142 is fixedly disposed at one end of the first sliding plate 141, and the first limiting plate 142 is slidably connected to the backrest 12.

[0043] The second limiting plate 143 is fixedly disposed at the other end of the first sliding plate 141, and the second limiting plate 143 is slidably connected to the backrest 12.

[0044] The support member 15 includes: a support frame 151, a first clamp 152, and a second clamp 153.

[0045] The support frame 151 is rotatably mounted on the first slide plate 141, and the cross-section of the support frame 151 is an isosceles trapezoid.

[0046] The first locking piece 152 is fixedly mounted on the first sliding plate 141, and the first locking piece 152 is used to lock the shorter bottom edge of the support frame 151.

[0047] The second clip 153 is fixedly mounted on the first slide plate 141. The second clip 153 is located on one side of the first clip 152. The second clip 153 is used to hold the shorter bottom edge of the support frame 151.

[0048] The first slide plate 141 has a first placement groove 141a, which is configured to cooperate with the support frame 151 to accommodate the support frame 151.

[0049] Specifically, after the support frame 151 is flipped out of the first placement slot 141a, it can form an obtuse angle with the first slide plate 141, and the longer bottom edge of the support frame 151 contacts the ground.

[0050] In this embodiment, by first pulling the first slide plate 141 out of the backrest 12 to a suitable length, the first limiting plate 142 and the second limiting plate 143 will provide stable limiting and support for the first slide plate 141; then, the support frame 151 is flipped out of the first placement slot 141a and pressed against the ground to provide support for the first slide plate 141.

[0051] like Figure 2-4 As shown, in one embodiment of this application, the locking member 13 includes: a support rod 131, a locking gear 132, and a first spring 133.

[0052] The support rod 131 is rotatably mounted on the seat cushion 111 and passes through the backrest 12.

[0053] The locking gear 132 is fixedly disposed at one end of the support rod 131, and the locking gear 132 is inserted into the seat cushion 111.

[0054] The first spring 133 is disposed inside the seat cushion 111. The first spring 133 is disposed on the side near the locking gear 132. One end of the first spring 133 abuts against the support rod 131, and the other end of the first spring 133 abuts against the seat cushion 111.

[0055] The seat cushion 111 has a locking groove 111a, and the locking gear 132 is inserted into the locking groove 111a.

[0056] The support rod 131 is also fixedly provided with a first limiting block 16 and a second limiting block 17, which are respectively provided at the connection between the chair back 12 and the support rod 131.

[0057] The first limiting block 16 is slidably connected to the chair back 12, and the second limiting block 17 is slidably connected to the chair back 12.

[0058] Specifically, the support rod 131 is cylindrical, and the first limiting block 16 and the second limiting block 17 on the support rod 131 are slidably connected to the backrest 12, so that the backrest 12 slides only along the axis of the support rod 131, and the backrest 12 rotates synchronously when the support rod 131 rotates.

[0059] In this embodiment, by pressing the support rod 131, the first limiting block 16 and the second limiting block 17 will slide relative to the backrest 12 simultaneously, the first spring 133 will be compressed, and the locking gear 132 will disengage from the locking groove 111a. At this time, the backrest 12 can rotate relative to the seat cushion 111.

[0060] When the support rod 131 is released, the first spring 133 will cause the locking gear 132 to insert into the locking groove 111a under the elastic restoring force, thereby locking the angle between the backrest 12 and the seat cushion 111.
