referring to fig. 2, two lateral sides of an arc-shaped support plate 2 are respectively and vertically slidably provided with a support rod 12, and a moving plate 11 is laterally and slidably provided with the corresponding support rod 12, when the device is in a use state, a schematic view is shown in fig. 1, when the neck of a patient needs to be pressed and relaxed, at this time, the vertical moving device of the support rods 12 drives the support rods 12 to move downwards and synchronously drives the moving plate 11 to move downwards, that is, the two moving plates 11 move downwards from the position shown in fig. 1 to the position shown in fig. 2, at this time, the moving plate 11 is driven by a moving plate 11 driving device arranged in the support rods 12 to move towards the direction away from each other, and finally, the moving plates 11 move to the position shown in fig. 3, at this time, the two moving plates 11 are completely retracted to the lower side of the arc-shaped;

referring to fig. 3, when the moving plates 11 are driven by the moving plate 11 driving device to move back and forth, one of the moving plate 11 driving devices synchronously drives the arc lifting plate 13 to move upwards through the arc lifting plate 13 transmission device connected with the moving plate 11 driving device, and when the two moving plates 11 are completely retracted into the arc-shaped support plate 2 (as shown in fig. 3), the arc-shaped lifting plate 13 is moved upward to the position as shown in fig. 3, and the two moving plates 11 do not interfere the upward movement of the arc lifting plate 13 while the arc lifting plate 13 moves upward, and the distance of the upward movement of the arc lifting plate 13 when the two moving plates 11 are completely retracted into the arc supporting plate 2 can be set, namely, the transmission ratio is set through the transmission device of the arc lifting plate 13, so that the upper arc surface of the arc lifting plate 13 is equal to the upper arc surface of the arc supporting plate 2 in height or slightly lower than the upper arc surface of the arc supporting plate 2;

referring to fig. 12, a plurality of arc-shaped frames 14 are arranged on an arc-shaped lifting plate 13 at intervals along the arc-shaped surface of the arc-shaped lifting plate, a telescopic spring 15 is connected between the arc-shaped frames 14 and the arc-shaped lifting plate 13, referring to fig. 13, a traverse plate 16 is transversely and slidably arranged in the arc-shaped frames 14, a return spring 17 is connected between the traverse plate 16 and the arc-shaped frames 14 (we perform round-chamfering on the lower end surfaces of the two traverse plates 16, as shown in fig. 14), a first cam 18 corresponding to the arc-shaped frames 14 is rotatably arranged on the arc-shaped lifting plate 13, the first cam 18 is connected with a cam driving device, referring to fig. 12, in an initial state, one end with a larger diameter of the first cam 18 faces the arc-shaped frames 14 and is just not contacted with the lower end surfaces of the two traverse plates 16, when the neck of a patient needs to be pressed and loosened, the first cam driving, along with the rotation of the first cam 18, the end with the smaller diameter of the first cam 18 firstly touches the lower end surface of the two traverse plates 16 to carry out the rounding and forces the two traverse plates 16 to move transversely in the arc-shaped frame 14 (i.e. to slide in the direction away from each other and cause the return spring 17 to be compressed), and the process can realize the pressing and releasing of the neck of the patient along the plane where the muscle of the neck of the patient is located, so that after the two traverse plates 16 move to the farthest distance in the arc-shaped frame 14 under the action of the first cam 18, along with the continuous rotation of the first cam 18, the arc-shaped frame 14 is driven to move upwards and the expansion spring 15 is stretched, so as to realize the pressing and releasing of the muscle of the neck of the patient in the direction perpendicular to the neck of the patient (refer to the illustration in figure 15), along with the continuous rotation of the first cam 18, so that the end with the smaller diameter of the first cam, the two traverse plates 16 move towards the direction of approaching each other under the action of the return spring 17 and finally move to the initial position, and at the same time, the arc-shaped frame 14 also moves downwards under the action of the extension spring 15 and also moves to the initial position, and at this time, a cycle of pressing and relaxing treatment on the neck muscles of the patient is completed;
