The scratching and touching functions can cooperate seamlessly and efficiently, thereby improving the overall performance of the device body 1 and the work efficiency of clinical nursing.

[0032] Working principle: First, the main body 1 of the device is moved to the position where it needs to be used through the universal wheels at the bottom, and the patient is allowed to lie on the treatment bed. At this time, the upper screw 21 or the lower screw 22 in the detachable structure 2 is rotated to adjust the length to an appropriate width. After installation, the controller starts the two hydraulic cylinders 32 to lift the lifting platform. At this time, apply medicine on the patient's area in advance. When scratching and touching operations are required, the two-way motor 5 is started to rotate, and the turntable 44 in the scratching mechanism 4 rotates, driving the linkage rod 43 and the grab block 42 to slide on the sliding plate 41. The large gear 61 simultaneously drives the four side gears 62, the rotating drum 63, the inner gear ring 64 and the inner gear 65 to transmit, and the rotating shaft 66 rotates to drive the active wheel 75 and the driven wheel 76 at the bottom of the touching mechanism 7 to rotate, driving the swing block 77, the swing rod 79 and the touching ball 791 to regularly scratch and touch the patient's area, and the treatment effect is good. At this point, the entire workflow is completed.
