[0034] The motor 41, the electric push rod 6 and the connecting piece 7 are prior arts, and the structural principles will not be repeated in detail.

[0035] Principle and process of the utility model:

[0036] When the device is used for pressing treatment of the patient along the direction of the spine, the patient's face is downward, the back is upward, and the patient is lying on the massage bed 1, and the face is placed on one side of the headrest. The mounting seat 8 is rotated by 90 degrees through the connecting piece 7, and the massage roller body 20 is arranged along the direction of the spine. A plurality of groups of ear plates 25 are symmetrically arranged inside the two arc-shaped rods 9 from top to bottom. The spring one 11 can switch positions between any group of ear plates 25, and the stress degree of the patient during the pressing action can be adjusted. The motor 41 is started, the output shaft of the motor 41 rotates to drive the lead screw 42 to rotate, and the sliding block 44 connected with the lead screw 42 in screw thread is slid in the cavity one 16 to the position corresponding to the spine of the patient. Then the electric push rod 6 is started, the output shaft of the electric push rod 6 makes up-and-down reciprocating motion, the massage roller body 20 is massaged along the direction of the spine, and during the rising process, the spine of the patient is pressed and massaged reciprocally under the stretching force of the spring one 11. The insertion block 1710 fixedly connected with the push rod one 175 is inserted into the insertion cavity 1716 by pressing the push rod one 175, and the inclined surface of the right-angled triangular clamping block 1713 slides into the sliding groove five 1711 under the force, and the spring five 1712 is pressed. When the insertion block 1710 is inserted into the insertion cavity 1716, the right-angled triangular clamping block 1713 corresponds to the position of the clamping groove four 1717, and is clamped in the clamping groove four 1717 under the action of the spring five 1712. At this time, the push rod one 175 cannot rebound under the action of the spring four 178, and the operator does not need to press the push rod one 175 with his hand all the time. The push rod one 175 acts on the inclined surface of the inclined surface groove 174, so that the friction block 172 is subjected to the force in the direction of the sliding groove two 171, and the friction block 172 slides into the sliding groove two 171. The friction block 172 no longer abuts against the rotating shaft one 19, so that there is no friction force between the rotating shaft one 19 and the friction block 172, and the sleeve 151 and the massage roller body 20 can slide on the rotating shaft one 19. The clamping ball 154 clamped in one of the clamping grooves one 156 slides out of the clamping groove one 156. The clamping ball 154 is clamped in different clamping grooves one 156, so that the massage roller body 20 is fixed at different positions of the rotating shaft one 19, and the distance between a group of massage roller bodies 20 can be adjusted. When the patient is fat, the two massage roller bodies 20 at both ends of the rotating shaft one 19 can be adjusted to increase the distance between the two massage roller bodies 20, so that the distance between a group of massage roller bodies 20 can be adjusted flexibly. When the appropriate distance is adjusted, the sleeve 151 and the massage roller body 20 cannot slide on the rotating shaft one 19, the push rod one 175 rebounds to the original position under the action of the spring four 178, the friction block 172 no longer receives the pushing force of the push rod one 175,Under the action of spring three 173, it bounces back to the original position, and the surface of the rotating shaft 1 9 is in contact, and the friction between the friction block 172 and the rotating shaft 1 9 exists friction, so that the sleeve 151 and the massage roller body 20 cannot slide on the rotating shaft 1 9.
