One end of the trigger block 300 passes through the locking groove 211, and the other end of the trigger block 300 is provided with a second trigger surface 310. When the second turntable 210 rotates relative to the first turntable 110 in one direction, the second trigger surface 310 is driven to contact the first trigger surface 111, and the trigger block 300 is pushed away from the first turntable 110 through the second trigger surface 310 and the first trigger surface 111.

[0048] Among them, the front arm bodies 400 are provided with a third turntable 410 and a second contact portion 420. The third turntable 410 is rotatably connected to the second turntable 210, and by rotating, the first contact portion 220 can be brought into contact with the second contact portion 420 so that the rear arm bodies 200 and the front arm bodies 400 are joined together to form an armrest.

[0049] Among them, the locking block 500 is located between the second turntable 210 and the third turntable 410 and can move along the radial direction of the third turntable 410. The locking block 500 can be inserted into or separated from the locking groove 211. The trigger block 300 contacts the locking block 500. When the trigger block 300 moves away from the first turntable 110, it pushes the locking block 500 to separate from the locking groove 211.

[0050] Specifically, when the locking block 500 is inserted into the locking groove 211, the third turntable 410 is in a locked state and cannot rotate relative to the second turntable 210. When the second turntable 210 rotates in one direction relative to the first turntable 110, it drives the second trigger surface 310 to contact the first trigger surface 111. Continuing to rotate can push the trigger block 300 through the second trigger surface 310 and the first trigger surface 111, and further push the locking block 500 to separate from the locking groove 211, making the locking block 500 in an unlocked state.

[0051] In this embodiment, in the locked state, the states of the rear arm body 200 and the front arm body 400 can be ensured to be non-separable or non-contact to prevent accidental pinching of children. In the unlocked state, the first contact portion 220 and the second contact portion 420 can be brought into contact by rotation so that the rear arm body 200 and the front arm body 400 are joined to form an armrest, or the first contact portion 220 and the second contact portion 420 can be separated to lower the front arm body 400.

[0052] As Figures 1 - 10 shown, on the basis of the above embodiment, a first elastic member 600 is further included.

The first elastic member 600 can push the locking block 500 away from the third turntable 410.

[0053] In this embodiment, the elastic member can push the locking block 500 away from the third turntable 410, so that the locking block 500 has a tendency to insert into the locking groove 211 in the normal state. When the second turntable 210 and the first turntable 110 rotate relative to each other and unfold to a certain extent and the third turntable 410 rotates until the locking block 500 is aligned with the locking groove 211, the locking block 500 automatically inserts into the locking groove 211 to complete the locking, which is very convenient.

[0054] As Figures 1 - 10As shown, on the basis of the above-described embodiment, the third turntable 410 is provided with an unlocking groove 411. The locking block 500 and the elastic member are both located within the unlocking groove 411. One end of the elastic member contacts the third turntable 410 through the bottom of the unlocking groove 411. The depth of the locking groove 211 is less than the thickness of the locking block 500. When one end of the locking block 500 contacts the bottom of the locking groove 211, the other end of the locking block 500 is located within the unlocking groove 411.

[0055] In the present embodiment, the depth of the locking groove 211 is less than the thickness of the locking block 500. Therefore, when one end of the locking block 500 contacts the bottom of the locking groove 211, the other end of the locking block 500 is located within the unlocking groove 411, that is, a part of the locking block 500 always remains within the unlocking groove 411 to prevent the locking block 500 from completely entering the locking groove 211 and destroying the locked state.

[0056] As Figures 1 - 10 shown, on the basis of the above-described embodiment, the locking block 500 is provided with a receiving groove 510. The other end of the elastic member contacts the locking block 500 through the bottom of the receiving groove 510.

[0057] In the present embodiment, one end of the elastic member contacts the third turntable 410 through the bottom of the unlocking groove 411, and the other end of the elastic member contacts the locking block 500 through the bottom of the receiving groove 510. Therefore, when the third turntable 410 is in the unlocked state, the elastic member can be completely concealed within the receiving groove 510 to prevent interference with the movement of the locking block 500.

[0058] As Figures 1 - 10 shown, on the basis of the above-described embodiment, the first contact portion 220 is provided with a positioning protrusion 221, and the second contact portion 420 is provided with a positioning recess 421.
