Referring to fig. 1 to 3, the present invention discloses a bracket for supporting an arm, which includes a hand rest 1, a connecting portion 2 and a clamping portion 3. Wherein the hand rest 1 is arranged in an arc shape and used for supporting the arm, and the problem that the arm is suspended when a user uses a computer is solved. Here, in order to further improve the comfort of arm fitting, a massage touch point (not shown) is further provided on the upper surface of the hand rest 1. One end of the connecting part 2 is connected with the hand support 1, and the connecting part 2 can adopt rod connecting structures such as a hinged support and a telescopic rod. And the other end of the connecting part 2 is connected to a clamping part 3, and the clamping part 3 can be clamped at the edge of the table, so that the bracket 100 is fixed on the table.

In the present embodiment, the connecting portion 2 includes a first connecting rod 21 and a second connecting rod 22 arranged side by side. One end of the first connecting rod 21 is rotatably connected with the hand rest 1, and one end of the second connecting rod 22 is rotatably connected with the clamping part 3. The other end of the first connecting rod 21 and the other end of the second connecting rod 22 are respectively provided with a mounting hole (not shown), and the top and the bottom of the two mounting holes are respectively provided with a connecting piece 23, that is, the free ends of the two connecting rods are respectively inserted into a mounting cavity enclosed by the two connecting pieces 23. The bracket 100 further comprises two connectors 24, each connector 24 being inserted through one of the coupling tabs 23 and a respective mounting hole onto the other coupling tab 23.

Above-mentioned technical scheme, connecting portion 2 respectively with hand rest 1, clamping part 3 swing joint, and connecting portion 2 comprises two connecting rods that set up side by side, two connecting rods pass through connection piece 23 and connecting piece 24 cooperation formation swing joint. As shown in fig. 1, the bracket 100 has four rotary joints, so that after the arm is placed on the hand rest 1, the four rotary joints can freely move horizontally or rotate freely by 360 degrees in cooperation with the hand, namely the arm is suspended, so that a good sitting posture is maintained, the user can work comfortably, and the arm and shoulder strain is effectively relieved. And the arm length of the bracket 100 can be adjusted at will according to actual needs by adopting the double-connecting-rod arrangement, so that the use is convenient.

In one embodiment, referring to fig. 1 and 3, a connecting seat 211 is disposed at one end of the first connecting rod 21, a mounting post 212 is protruded from a top of the connecting seat 211, a through hole 213 is vertically disposed on the mounting post 212 along a height direction thereof, a mounting seat 11 is disposed at a bottom of the hand rest 1, and a connecting shaft 12 extends downward from the mounting seat 11.
