The twisting seat 430 is slidably connected to the arc-shaped guide rail 420, and can slide and lock along the arc-shaped guide rail 420 by being driven by the twisting driving mechanism. One end of the lower clip arm 440 is rotatably connected to the swivel base 430 by a vertical shaft. The iliac pressing plates 450 are two arc plates with opposite openings, and can hold the two sides of the hip tightly, and the middle part of each iliac pressing plate 450 is connected with the free end of a lower clamping arm 440.

The torsion driving mechanism comprises an arc-shaped rack fixed on the arc-shaped guide rail 420, a torsion motor fixed on the torsion seat 430 and a torsion gear, and the torsion gear is fixed on an output shaft of the torsion motor and is in meshing transmission with the arc-shaped rack.

And, an arc-shaped guide groove is formed at least on the upper end surface of the arc-shaped guide rail 420, and a guide wheel capable of rotating in the guide groove is fixed on the twisting seat 430 to ensure the stability of twisting operation.

The second synchronous opening and closing mechanism comprises two opening and closing gears which are respectively fixed on the two vertical shafts, the two opening and closing gears are in opposite meshing transmission, a shaft brake is arranged on at least one of the vertical shafts, the opening and closing of the two upper clamping arms 260 are manually adjusted, and the two upper clamping arms are locked through the shaft brake after the adjustment is completed.

Or a shaft brake is not used, the shaft brake is coaxially fixed with a motor shaft of an opening and closing driving motor through one of the vertical shafts, and the two lower clamping arms 440 can be driven to synchronously rotate back to back or relatively rotate through the forward rotation and the reverse rotation of the closing driving motor, so that the opening and the closing and the locking of the two lower clamping arms 440 are realized.

In this embodiment, at least one vertical guide rail is disposed on the column 100, the cross section of the vertical guide rail is T-shaped, and the middle sliding seat is slidably connected to the vertical guide rail and is limited in the horizontal plane by a T-shaped structure.

The third lifting driving mechanism comprises a vertical rack, a lifting driving motor and a lifting driving gear, the vertical rack is fixed on the stand column 100, the lifting driving motor is fixed on the lower sliding seat 410, and the lifting driving gear is fixed on a motor shaft of the lifting driving motor and is meshed with the vertical rack for transmission. The lifting driving of the lower slider 410 can be realized by the forward rotation and the reverse rotation of the motor, and the positioning of the lower slider 410 is realized by the engagement of the gear rack mechanism.

The third lifting driving mechanism, the second lifting driving mechanism and the first lifting driving mechanism can share one vertical rack.

Example fourteen

According to a specific embodiment of the disclosed vertical waist massage device, the middle part of the iliac pressing plate 450 is rotatably connected with the lower clamping arm 440 through a vertical shaft and can be locked.
