[0034] The support suspension rod 21 is inserted into the flange end of the flange shaft 3 and is fixedly connected to the flange shaft 3.
[0035] Support module 21 is installed at the suspension end of support suspension rod 22 and is used to support the target;
[0036] When the target is placed on the support module 21, the support module 21 provides support to the target, and when the target moves, it drives the support suspension rod 22 to rotate relative to the mounting base 1, triggering the buffer 4 to generate movement damping.
[0037] The mounting seat 1 is used to connect the suspension type rotating support arm device to the corresponding rehabilitation training equipment. The mounting seat 1 is fixedly connected with the hand function rehabilitation training table.

[0041] Further, as shown in Figure 2 The structure of the mounting seat 1 includes:
[0042] The mounting seat 1 is provided with two bearings 2, and the bearings 2 are stacked and arranged in a circular tubular space of the mounting seat 1. The circular tubular space is consistent in shape and size with the bearings 2, and the two are tightly matched and ensure that the bearings 2 can rotate relative to the circular tubular space. The height of the circular tubular space is slightly greater than the sum of the heights of the two bearings 2, thereby reducing the resistance between the contact side end surface of the bearings 2 and the mounting seat 1. The two bearings 2 are provided with a circular hole in the middle, and the diameter of the circular hole is equal to the diameter of the flange shaft 3, and the two are tightly matched.

[0063] Wherein, the support rod 10 is used to make the suspension rod 14 set above the rehabilitation training equipment, and the suspension rod 14 can rotate around the support rod 10, so as to realize the free movement of the support module 21 in a certain range. Preferably, the support rod 10 is a telescopic rod, and the height of the suspension rod 14 is increased or decreased with the extension or shortening of the telescopic length of the support rod 10. The technical effect of improving the adaptability of the suspension type rotating arm support device of the application to patients with different body shapes is realized.
[0064] In addition, optionally, the rotating head 12 is used to fixedly connect the suspension rod 14 and the support rod 10. The rotating head 12 is provided with two vertical circular tubular accommodation spaces, the inner diameters of the two circular tubular spaces are respectively adapted to the outer diameters of the suspension rod 14 and the support rod 10, and can be closely matched with the suspension rod 14 and the support rod 10. Among them, the bottom surface of the circular tubular accommodation space matched with the rotating head 12 and the support rod 10 is provided with a screw hole, which is used to connect and fix the rotating head 12 and the support rod 10 through the screw set 13.
