[0025] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0026] like Figures 1 to 3 As shown, the multi-angle adjustable medical support arm of the utility model includes a first adjusting member 11, and the first adjusting member 11 has a rotatable first movable support arm assembly 20. The first movable support arm assembly 20 can be adjusted at multiple angles on the first adjusting member 11 to change the movable angle of the first movable support arm assembly 20. In addition, the first movable support arm assembly 20 and the second movable support arm assembly 40 are connected by a connecting member 31. The second movable support arm assembly 40 can be adjusted at multiple angles through the connecting member 31, and then installed on the therapeutic device through the first base 10 and the second base 51 to adjust the angle of the treatment head on the therapeutic device, thereby improving the practicability of the therapeutic device.

[0027] Specifically, the first adjusting member 11 is mounted on the first base 10, and the first base 10 can be mounted on the therapeutic device by bolts or screws. It should be noted that in this embodiment, the first adjusting member 11 is hemispherical in shape, which is convenient for adjusting the angle of the first movable arm assembly 20.

[0028] The first movable arm assembly 20 is composed of a first arm 21, a fastener 23, and a second arm 24. Specifically, the first arm 21 and the second arm 24 are connected by bolts, which facilitates the installation and removal of the first movable arm assembly 20. Specifically, a first mounting hole 22 is provided on the first arm 21 and the second arm 24, and a fastener 23 is installed in the first mounting hole 22. The fastener 23 is used to install the second arm 24 and the first arm 21 together.

[0029] In addition, a first connecting portion 25 extends from both ends of the first support arm 21 and the second support arm 24. The first connecting portion 25 has a first accommodating cavity 251 on one side facing the first adjusting member 11. In this embodiment, the first accommodating cavity 251 is arc-shaped, and the first accommodating cavity 251 is adapted to the outer surface of the first adjusting member 11, so that the first support arm 21 and the second support arm 24 can be installed on the first adjusting member 11. With the above structure, the first movable support arm assembly 20 can be adjusted at multiple angles.

[0030] The second movable arm assembly 40 includes a third arm 41 and a fourth arm 42. Both ends of the third arm 41 and the fourth arm 42 are fixedly connected with a second connecting portion 45. The second connecting portion 45 is provided with a second accommodating cavity 451 on the side facing the connecting member 31. In this embodiment, the second accommodating cavity 451 is arc-shaped, and the second accommodating cavity 451 is adapted to the outer surface of the connecting member 31, so that the first arm 21 and the second arm 24 can be installed on the connecting member 31.

[0031] In one embodiment, the third arm 41 and the fourth arm 42 both have a second mounting hole 43, and a second fastener 44 can be installed in the second mounting hole 43. The second fastener 44 is used to install the third arm 41 and the fourth arm 42 on the connecting member 31, so as to facilitate the disassembly and installation of the second movable arm assembly 40.

[0032] In the first embodiment, the connecting member 31 has a first ball head 311 and a second ball head 312, and the shapes of the first ball head 311 and the second ball head 312 are both hemispherical. One end of the first movable arm assembly 20 is installed on the first ball head 311 through the first connecting portion 25 and the first accommodating cavity 251; one end of the second movable arm assembly 40 is installed on the first ball head 311 through the second connecting portion 45 and the second accommodating cavity 451. Thus, the installation of the first movable arm assembly 20 and the second movable arm assembly 40 is completed.
