The first direction and the second direction meet a vertical condition.

[0035] In this embodiment, the armrest can be applied to various types of chairs including but not limited to office chairs, sofa chairs or computer chairs, and can be used in various office scenes, public places or homes. The first direction is the width direction of the armrest, and the second direction is the length direction of the armrest. To be ergonomic, the body 3 of the armrest has an arc. It can be understood that to facilitate movement and adjustment, the base 1 and the guide member 2 also have an arc, and the size of the arc can be adaptively designed according to actual needs. Since the base 1 of the handrail is fixed, the guide member 2 is slidably connected to the base 1, so that the guide member 2 can move relative to the base 1 along the first direction. Since the body 3 is slidably connected to the guide member 2, the body 3 can move relative to the guide member 2 along the second direction. Therefore, when a force is applied to the body 3 along the first direction, the relative movement of the body 3 along the first direction is limited by the guide member 2, so that the body 3 and the guide member 2 remain relatively still, and the two can be adjusted and moved relative to the base 1 along the first direction as a whole; when a force is applied to the body 3 along the second direction, the guide member 2 is limited by the base 1 in the relative movement along the second direction, so that the guide member 2 and the base 1 remain relatively still, so that the body 3 can be adjusted and moved relative to the whole formed by the guide member 2 and the base 1 along the second direction. In this way, the problem that the handrail cannot achieve regional expansion is solved, and the body 3 of the handrail can slide in both the first direction and the second direction, thereby increasing the adaptability of the handrail.

[0038] In this embodiment, at least one raised rib 25 is provided on the side of the guide member 2 close to the base 1, and the raised rib 25 is located beside the first guide groove 21 and meets the parallel condition with the first guide groove 21. Correspondingly, a guide groove 12 is provided on the base 1, and the raised rib 25 is placed in the guide groove 12, so as to prevent the guide member 2 from rotating when sliding relative to the base 1 along the first direction, and play a guiding and limiting role. The positioning structure 11 can specifically include a screw and a gasket, the screw passes through the first guide groove 21 and is fastened to the base 1, and the gasket is arranged between the screw head of the screw and the bottom of the open groove 24, so as to increase the contact area, reduce the pressure, and prevent the screw from loosening; or, the positioning structure 11 can be a positioning column formed on the surface of the base 1, the cross section of the positioning column is circular or runway-shaped, the positioning column is provided with a hollow hole, and the inner wall of the hollow hole is provided with a screw thread, the positioning column passes through the first guide groove 21, and is fastened to the positioning column by a screw, and a gasket is arranged between the screw head of the screw and the positioning column, so as to increase the contact area, reduce the pressure, and prevent the screw from loosening. Therefore, when the guide member 2 is subjected to an external force in the first direction, it can move along the first direction relative to the base 1 .

[0039] Reference Figure 5 As shown, in one embodiment, the armrest further includes a fixing structure 5 , the fixing structure 5 includes a fixing member 51 and a gasket 52 , and the fixing member 51 passes through the gasket 52 and is fastened to the positioning structure 11 .

[0040] In this embodiment, the positioning structure 11 is a positioning column formed on the surface of the base 1, the cross section of the positioning column is circular or track-shaped, the positioning column is provided with a hollow hole, the inner wall of the hollow hole is provided with a screw thread, and the positioning column passes through the first guide groove 21, wherein the width of the first guide groove 21 is adapted to the positioning column. The fixing member 51 is specifically a screw, the fixing member 51 is tightly connected to the positioning column, and the gasket 52 is provided between the screw head of the screw and the positioning column, thereby increasing the contact area, reducing the pressure, and preventing the screw from loosening. As a result, when the guide member 2 is subjected to an external force in the first direction, it can move relative to the base 1 along the first direction.

[0041] Reference Figure 6 and Figure 8 As shown, in one embodiment, the armrest further includes a connecting structure 4, the guide member 2 is provided with a second guide groove 22, and the second guide groove 22 is parallel to the second direction, and the body 3 is slidably connected to the second guide groove 22 via the connecting structure 4.

[0042] Specifically, in one embodiment, the guide member 2 includes a first surface close to the body 3 and a second surface close to the base 1 , the second surface is provided with a groove 23 , and the second guide groove 22 is opened at the bottom of the groove 23 .

[0043] Further, in an embodiment, the connection structure 4 includes an elastic member 41, a through hole 411 is opened at the center of the elastic member 41, the elastic member 41 is clamped in the groove 23, and the through hole 411 corresponds to the second guide groove 22 and is connected to the second guide groove 22. The side wall 231 of the groove 23 is wavy, and the side surface 412 of the elastic member 41 that contacts the two side walls 231 is contoured with the side wall 231.

[0044] In this embodiment, the wavy side wall 231 has a convex part and a concave part, wherein the convex part and the concave part are alternately arranged to form a wavy shape, and the thickness of the elastic member 41 is less than the depth of the groove 23 to prevent the elastic member 41 from interfering with the base 1 during sliding and affecting the sliding effect. The side surface 412 of the elastic member 41 that contacts the side wall 231 of the groove 23 is contoured with the side wall 231, specifically, the side surface 412 of the elastic member 41 is in a "convex" shape, and the protruding part of the "convex" shape is engaged with the concave part on the side wall 231 of the groove 23. In addition, a convex point 414 is also provided at the vertex of the "convex" shape, and accordingly, a slot for accommodating the convex point 414 is provided at the second surface of the guide member 2 to prevent the elastic member 41 from being inverted during assembly. Since the armrest body 3 is fixedly connected to the elastic member 41, and the side wall 231 of the groove 23 is wavy, when the elastic member 41 moves along the second direction, whenever the protruding portion of the elastic member 41 engages with the recessed portion of the side wall 231 of the groove 23, the body 3 can remain stationary there. When a greater external force is applied to the body 3 in the second direction, the body 3 drives the elastic member 41 to slide along the groove 23.
