[0018] The present invention will be described in further detail below with reference to the accompanying drawings.

[0019] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0020] An embodiment of the present invention: Figure 1As shown, a quick-change device for a massage robot's physiotherapy head includes a mother plate 2 for connecting to the end of the robot, and a sub-plate 13 for connecting to various physiotherapy heads; Figure 2 and Figure 3 As shown, the mother disk 2 has a central hole for setting a quick-change structure, and there are symmetrical guide holes 8 on both sides of the mother disk 2 connected to the central hole. A push rod 9 is respectively provided in the guide hole 8. One end of the push rod 9 is connected to the button 1 outside the guide hole 8, and the other end is connected to a pair of buckles 3 in the central hole of the mother disk 2. An elastic element is provided between the buckles 10. Pressing the button 1 can make the buckles 3 move toward the center. Release the button 1 and the buckles 3 are pushed to both sides by the elastic element to reset. The sub-disk 13 is provided with a clamping hole 10 for clamping the buckle 3. Pressing the button 1 can make the clamping hole 10 of the sub-disk 13 clamped on the mother disk 2, or make the sub-disk 13 detached from the mother disk 2. When the utility model is used, Figure 4 As shown, the master disc is first mounted on the robot 14, and then Figure 3 As shown, by pressing the buttons 1 at both ends of the mother tray 2, the push rods 9 drive the buckles 3 to overcome the compression of the elastic elements and move toward the center. At this time, the sub-tray 13 with the massage head installed is placed on the mother tray 2. Then, the buttons 1 are released, and the buckles 3 are reset and locked to the sub-tray 13 under the action of the elastic elements, completing the installation.
