M261121 V. Creation description (3) block (2 1 2) and a rotating shaft (2 2). Among them, an armrest (2), one end of which is riveted to the connection extended by the slide (2 1). On the block (2 1 4), the other end is provided with a rotating shaft (2 2) and is sleeved with the rod body (2 3); a slide base (2 1), a central part of the slide base (2 1) is provided with a A through hole is provided for passing through the rod body (2 3), and one end of the sliding seat (2 1) is extended with a connecting block (2 1 4), which can be riveted at one end of the armrest (2), and is a rod accessible Design of free sliding up and down on the body (2 3);

A claw-shaped projection (2 1 1), which is riveted to one side of the sliding seat (2 1), and a lower projection (2 1 2) is extended at the lower end; the lower projection (2 1 2), It is extended at the lower end of the claw-shaped projection (2 1 1); a rotating shaft (2 2) is set at one end of the armrest (2), and is connected with the rod body (2 3), and can be connected to When the armrest (2) is folded upwards or folded downwards, it is rotated with an angle to facilitate the expansion or storage of the folded chair. [Embodiment]

Please refer to the seventh and tenth pictures of this creation. When the user wants to unfold the folding chair, first lift the armrest (2), and at the same time, make the slider (2 1) on the rod body (2 3) After sliding upward, and stopping at the connecting block (2 3 1) at the top of the rod body (2 3), press the lower projection (212) extending below the claw projection (211) inward, and the claw projection Block (2

Page 7 M261121 V. Creation instructions (4) 1 1) After fitting with the lugs (2 3 1) on the connecting block (2 3 1) and releasing, you can easily complete the folding chair unfolding action. Please also refer to the eleventh and twelfth pictures of this creation. When the user wants to collapse the folding chair, first he only needs to press the lower protrusion (212) extended below the claw protrusion (211). After separating the claw-shaped projections (211) from the lugs (23 1) on the connection block (232), and sliding the sliding seat (2 1) downward, at the same time, the folding chair can be moved closer to the center. When the seat (2 1) slides down to the bottom end of the rod body (2 3), the folding chair can be folded into a bunch, which is convenient for users to carry and store. Furthermore, please refer to the fifteenth of this creation for reference. This is a three-dimensional view of this creation applied to the folding table (3). The two ends of the slider (3 1) each extend with an engaging block (3 1 1). It is used for riveting one end of the armrest (3 3 1), and the slide seat (3 1) passes through the main support rod (3 2) (as shown in the sixteenth figure) and the rotating shaft (3) at the center of the folding table (3). 3) The rod body (34) located at the other end of the armrest (33 1) is to facilitate the folding table (3) to slide down the slide seat (3 1) on the main support rod (3 2) and Close the folding table (3) inward and fold it into a bunch (as shown in Figure 18), or unfold it outside. Please refer to the nineteenth figure of this creation again, which is a diagram of another embodiment of this creation applied to the folding table (4), in which the sliding seat (4 2) can also be worn on the pole body (4 3), A connecting block (4 2 1) is extended on either side of the sliding seat (4 2) and is riveted to one end of the armrest (4 1 1), and a rotating shaft (4 1) is attached to the main support rod (4 4) at the top, and the sliding seat (4 2) can slide downwards when folded, by rotating the shaft (4 1)
