[0011] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0012] Depend on Figures 1 to 5 The present invention comprises a thigh fixing shell 1 which is rectangular and has an opening facing right. A connecting block 2 is slidably connected to the right side of the thigh fixing shell 1. A calf fixing shell 3 is provided at the right end of the connecting block 2. A lifting block 4 which can move up and down is provided on the thigh fixing shell 1 and the calf fixing shell 3 respectively. An arc-shaped massage shell 5 is provided at the upper end of the lifting block 4. An arc-shaped sliding groove 6 is provided on the arc-shaped surface of the massage shell 5. A massage plate 7 which can slide left and right is provided in the sliding groove 6. A plurality of massage balls 8 are provided on the ball joint of the massage plate 7. A popliteal pad 9 is provided at the upper end of the calf fixing shell 3.

[0013] In order to enable the lifting block 4 to move up and down, the lifting block 4 is slidably connected to the thigh fixing shell 1 and the calf fixing shell 3. A rectangular and left-to-right through-giving groove 10 is provided at the left end of the lifting block 4. An extrusion block 11 that can slide back and forth and can contact the lifting block 4 is provided in the thigh fixing shell 1 and the calf fixing shell 3. The lower end surface of the extrusion block 11 is an inclined surface with a lower front and a higher rear.

[0014] In order to allow the extrusion block 11 to slide forward and backward, the front ends of the thigh fixing shell 1 and the calf fixing shell 3 are respectively rotatably connected with studs 12 which are axially forward and backward and threadedly connected to the extrusion block 11 on the corresponding side.

[0015] In order to facilitate the rotation of the stud 12, the front end of the stud 12 passes through the thigh fixing shell 1 and the calf fixing shell 3 and is coaxially provided with a knob.

[0016] In order to facilitate the resetting of the lifting block 4, the lower end of the lifting block 4 is connected to the thigh fixing shell 1 and the calf fixing shell 3 via the compression spring 13.

[0017] In order to enable the massage plate 7 to slide left and right, the massage plate 7 is slidably connected to the massage shell 5, a plurality of teeth 14 are provided on the lower surface of the massage plate 7, a motor 15 is provided on the left side wall of the massage shell 5, and an incomplete gear 16 that can mesh with the teeth 14 is coaxially provided on the output shaft of the motor 15.

[0018] In order to facilitate the resetting of the massage plate 7, a resetting block is provided at the right end of the massage plate 7, and the resetting block is connected to the massage shell 5 via a spring 17.

[0019] In order to facilitate the fixation of the patient's limbs, the front end of the massage shell 5 is provided with a restraining belt 18, the free end of the restraining belt 18 is provided with a Velcro, and the rear side of the massage shell 5 is provided with a Velcro mother tape that can be bonded with the Velcro.

[0020] In order to facilitate the fixing and limiting of the connecting block 2, a plurality of limiting holes evenly distributed in the left and right directions are opened at the front end of the connecting block 2, and a limiting column 19 which can be inserted into the limiting hole is slidably connected to the front end of the calf fixing shell 3, and a pull plate is provided at the front end of the limiting column 19, and a tension spring is mounted on the limiting column 19 and located between the pull plate and the calf fixing shell 3.

[0021] When the utility model is in use, the thigh fixing shell 1 and the calf fixing shell 3 are first placed on the bed, and then the length is adjusted according to the length of the patient's lower limbs, and the pull plate is pulled forward, and the pull plate drives the limiting column 19 to move forward. After moving forward for a certain distance, the limiting column 19 is pulled out of the corresponding limiting hole, and the fixed limit is released. Then the calf fixing shell 3 is pulled to the right, and the calf fixing shell 3 drives the connecting block 2 to move to the right. When the calf fixing shell 3 moves to the right to a length suitable for the patient's lower limbs, the pulling is stopped and the pull plate is released. Due to the restoring force behind the tension spring, the limiting column 19 is driven to move backward. After moving backward for a certain distance, it is inserted into the corresponding limiting hole to re-realize the fixed limit, thereby preventing the calf fixing shell 3 from moving relative to the thigh fixing shell 1 during stretching rehabilitation.

[0022] After the adjustment is completed, the patient places the thigh in the massage shell 5 on the left, and the patient's calf in the massage shell 5 on the right, and the Velcro on the restraint belt 18 is respectively bonded to the corresponding Velcro mother patch, so as to fix and limit the patient's limbs and prevent the patient's limbs from moving during rehabilitation. After the fixation is completed, the lower surface of the patient's limb is in contact with the massage ball 8, and the motor 15 is turned on at this time, and the motor 15 drives the incomplete gear 16 to rotate, and the incomplete gear 16 rotates to mesh with the teeth 14 and drives the massage plate 7 to slide to the left, so that the massage ball 8 on it can achieve rolling massage of the patient's limbs;

[0023] When the motor 15 drives the incomplete gear 16 to rotate a certain angle, the incomplete gear 16 is disengaged from the plurality of teeth 14. At this time, due to the restoring force of the spring 17, the massage plate 7 is driven to slide to the right, thereby realizing a rolling massage of the patient's limb to the right. The massage plate 7 slides to the right for a distance and then returns to the initial position. At this time, the motor 15 continues to rotate, driving the incomplete gear 16 to rotate a certain angle again and then mesh with the teeth 14 again and drive the massage plate 7 to slide to the left again and realize rolling massage again, and then disengage again, and this is repeated to realize continuous massage of the patient's limb.

[0024] Then turn the knob, the knob drives the stud 12 to rotate, the stud 12 drives the two extrusion blocks 11 to move backward, the extrusion block 11 drives the two lifting blocks 4 to move downward, the lifting block 4 drives the massage shell 5 to move downward, and then drives the patient's lower limbs to move downward. After moving downward for a distance, the patient's popliteal fossa contacts the popliteal fossa pad 9 and realizes the top pressure on the popliteal fossa, thereby achieving stretching of the patient's knee area. After stretching is completed, rotate the stud 12 in the opposite direction. Due to the loss of extrusion of the extrusion block 11 and the upward restoring force of the spring 17, the massage shell 5 is driven to move upward, and the massage shell 5 drives the patient's lower limbs to move upward, and then the restraint belt 18 can be released.

[0025] Compared with the prior art, the beneficial effects of the utility model are: the massage shell, lifting block, squeezing block, etc. can realize automatic massage of the patient's lower limbs, prevent the formation of blood clots caused by poor blood circulation in the patient's lower limbs, and at the same time can realize top pressure on the patient's popliteal fossa, and then realize stretching of the knee, preventing muscle adhesion in the patient's knee area. This structure is simple, the conception is novel, it is easy to use and has strong practicality.
