[0039] Specifically, a first top spring (not shown) is further provided, and the first top spring is used to apply an elastic force to the swing member 31 to swing in the direction of inserting the lower end of the swing member 31 into the positioning hole 32.

[0040] Specifically, a first limiting groove 41 extending vertically is formed on one side of the lower end of the armrest, and the connecting seat 1 is provided with a limiting pin 42 partially extending into the first limiting groove 41. The armrest can move relative to the connecting seat 1 between the positions where the limiting pin 42 partially abuts against the top wall of the first limiting groove 41 and the limiting pin 42 partially abuts against the bottom wall of the first limiting groove 41, so as to prevent the armrest from completely detaching from the connecting seat 1.

[0041] Specifically, the limiting pin 42 and the connecting seat 1 are of an integrally formed structure or a detachable connection structure. When it is a detachable connection structure, the limiting pin 42 is a bolt screwed onto the connecting seat 1, and the rod portion of the bolt extends into the first limiting groove 41.

[0042] Specifically, a second limiting groove 43 extending vertically is further provided on one side of the connecting seat 1 close to the plug portion 33. The plug portion 33 can insert into the positioning hole 32 after passing through the second limiting groove 43, and the plug portion 33 can also move between the positions where it partially abuts against the top wall of the second limiting groove 43 and the bottom wall of the second limiting groove 43 along with the vertical reciprocating movement of the armrest.

[0043] Specifically, the armrest includes a first strip-shaped member 21 and a second strip-shaped member 22. The first strip-shaped member 21 is provided at the upper end of the second strip-shaped member 22, so that the whole armrest is in a "T" shape or a "Ren" shape.

[0044] Specifically, the second strip-shaped member 22 is a hollow structure with both ends open. The swing member 31 is located inside the second strip-shaped member 22. The upper end of the swing member 31 is rotationally matched with the upper end opening of the second strip-shaped member 22, and the driving portion extends out of the second strip-shaped member 22 and is exposed outside. The first strip-shaped member 21 is locked by screws or fixed by a snap structure at the upper end of the second strip-shaped member 22 and shields the upper end opening of the second strip-shaped member 22.

[0045] Specifically, one end of the first top spring elastically presses against the bottom wall of the first strip member 21, and the other end elastically presses against the top wall of the shift plate 34, or one end of the first top spring elastically presses against the inner wall of the second strip member 22, and the other end elastically presses against the swinging member 31.

[0046] Specifically, such as Figure 10 As shown, the first strip member 21 and the second strip member 22 are pivotally connected and can rotate horizontally relative to the second strip member. An adjustment slot 23 is provided inside the first strip member 21, and a strip-shaped positioning member 24 is movably provided in the adjusting slot 23. The positioning member 24 has a partial bottom that passes through the bottom wall of the first strip member 21 and is fixedly connected to the top of the second strip member 22 to realize the pivotal connection between the first strip member 21 and the second strip member 22. The side wall of the adjusting slot 23 is provided with a plurality of arc-shaped recesses 25, and the plurality of arc-shaped recesses 25 are adjacently distributed to form a wave shape.
