In the ninth embodiment, on the basis of the first embodiment, handles are fixed on the front and rear sides of the cylinder 1 for convenience of use.

It is noted that a bearing is arranged between the spline cylinder 7 and the shell 3, a bearing is arranged between the gear 2 and the cylinder 1, and a bearing is arranged between the shell 3 and the cylinder 1; the first annular plate 5 and the cylinder 1 can be fixed in various manners, such as welding, bonding and the like, and a plurality of bolt and nut structures can be adopted for fixing, and in the scheme, only the first annular plate 5 and the cylinder 1 are ensured to be fixed; the rollers 10 in the device interfere with each other from end to end, namely, the tail end of the former roller 10 and the front end of the latter roller 10 are overlapped together under the action of the corresponding torsion springs, so that the rollers 10 cannot do complete circular motion, and the rollers 10 can move on the legs along the spiral track along the legs; the adjacent two small shells 17 are in contact with each other, but the rollers 10 and 10 are not in contact with each other, so that the rollers 10 are not affected by each other when rolling along the legs; the rollers 10 on the two shells 3 are opposite in inclination direction, so that the kneading effect can be ensured during massage, and the leg surfaces can be fully pressed as far as possible.

When the device is used, the device is sleeved on the leg of a patient, then the square shaft 9 is tightly pressed on the surface of the leg under the action of the pressure spring, at the moment, the handle is held by hands and moves from bottom to top along the leg, and as a plurality of rollers 10 are extruded towards the middle of the cylinder 1 under the action of the square shaft 9 and the ends of the adjacent rollers 10 are mutually interfered, the rollers 10 are inclined, when the device moves along the leg, the rollers 10 can advance along a spiral track, the rollers 10 rotate in the cylinder 1 when rolling along the spiral, and meanwhile, the gear rings 4 on the two shells 3 rotate in opposite directions in the cylinder 1 under the action of the gears 2, so that the kneading effect on the leg is realized.

Because the diameter of the lower leg is smaller than that of the thigh, when the thigh is massaged, the roller 10 is forced to move to one side far away from the center of the cylinder 1, in the process, the roller 10 is always connected end to end under the action of the torsion spring, the periphery of the leg is always pressed by 360 degrees, of course, the roller 10 is pressed by the square shaft 9 to move towards the inside of the shell 3 through the spline shaft 8, the air pressure in the shell 3 is increased, and because the one-way valve on the cylindrical block 12 only enables air to pass from top to bottom, the cylindrical block 12 gradually moves upwards, and when the cylindrical block 12 moves to the upper side of the air passing hole 14, the air enters the air cylinder 13 through the air hole 14, and a plurality of pistons move upwards at the moment, so that the pressing force of the leg is always consistent; when massaging the lower leg from the thigh, the piston moves downward under the action of the compression spring and the cylindrical block 12 also moves downward under the action of the compression spring thereon, re-entering the gas into the chamber.

In the above massage from the thigh to the calf, even if the cylindrical block 12 reaches the lower side of the air hole 14, the air in the air cylinder 13 can smoothly enter the chamber due to the check valve.

The invention has the outstanding advantages and remarkable progress:

1. compared with the traditional massage, the invention uses the plurality of rollers 10 which are uniformly distributed around the legs and keep head-to-tail contact under the action of the torsion spring, so that the maximum area contact with the legs is ensured, and the blood in veins flows more quickly.

2. In the invention, the rolling shafts 10 are always inclined during massage, so that the shell 3 rotates in the cylinder 1, the rotation directions of the two shells 3 are opposite to each other, twisting and kneading forces are formed, and the rolling shafts 10 of the two shells 3 are combined with each other to realize omnibearing massage on the periphery of the leg, and can effectively force blood to flow quickly and inhibit thrombosis.

3. The invention can be well adapted to the diameters of all parts of the legs, and ensures that the massage force of all parts is kept consistent.

4. According to the invention, the massage pressing force can be adjusted, specifically, the screw at the upper end of the cylindrical shell 11 is screwed, when the distance between the lower end of the screw and the cylindrical block 12 is smaller, the resistance of upward movement of the cylindrical block 12 is larger, the cylindrical block 12 is not easy to push to the upper part of the air hole 14 by air pressure, the pressing force of the roller 10 on the leg is larger, and vice versa, so that the use of various stages and patients is facilitated, and the application range is increased.
