The cervical traction device of claim 1, wherein the power traction mechanism comprises a first driving mechanism and two traction components, the first driving mechanism is mounted on the shoulder pressing part, the two traction components are oppositely arranged at two sides of the shoulder pressing part, and both traction components are connected with the lower jaw bearing part; the first driving mechanism is used for driving the two traction assemblies to move so as to enable the lower jaw bearing part to reciprocate relative to the shoulder pressing part.

3. The cervical traction apparatus of claim 2, wherein the traction assembly comprises a housing, a fixed pulley, a first lift portion, and a traction rope;

the shell is fixedly connected with the pressure shoulder, and the fixed pulley is arranged inside the shell; the first lifting part is fixedly connected with the lower jaw bearing part, the first lifting part is connected with the shell in a sliding mode, a sliding groove is formed in the first lifting part, and the first lifting part can move back and forth relative to the fixed pulley along the length direction of the sliding groove;

a power output end of the first driving mechanism is provided with a reel for winding or releasing the traction rope, one end of the traction rope is connected with the reel, and the other end of the traction rope bypasses the fixed pulley and is connected with the first lifting part; the first driving mechanism drives the reel to rotate, so that the first lifting part drives the lower jaw bearing part to reciprocate along the length direction of the sliding groove.

4. The cervical traction apparatus as claimed in claim 3, wherein the bottom plate of the housing and the bottom plate of the first lift portion are provided with passages for the traction rope to pass through.

5. The cervical traction apparatus of claim 4, wherein the traction assembly further comprises a reversing wheel mounted on the shoulder pressing portion, the traction rope passing around the reversing wheel to pass vertically upward through the passage.

6. The cervical traction device of claim 1, wherein the powered traction mechanism comprises a second drive mechanism, a screw, and a second lift, the second drive mechanism being drivingly connected to the screw, the second lift being threadedly connected to the screw, and the second lift being connected to the chin rest; the second driving mechanism drives the screw to rotate along its own axis to reciprocate the second lifting portion along the axis of the screw.

7. The cervical traction device as claimed in claim 6, wherein the power traction mechanism further comprises a mounting housing fixedly connected to the pressing shoulder, the second driving mechanism, the screw and the second lifting portion are located inside the mounting housing, and an opening for the second lifting portion to pass through is provided on a top plate of the mounting housing.

8. The cervical traction device of claim 7, wherein the inner surface of the mounting housing is provided with a guide rib, and the length direction of the guide rib is parallel to the axis of the screw rod; the second lifting part is provided with a guide groove matched with the guide convex strip.

9. The cervical traction device of claim 6, wherein the second driving mechanism is connected to the screw via a gear transmission mechanism.

10. The cervical traction apparatus according to any one of claims 1 to 9, further comprising a tension sensor for detecting a traction tension provided by the power traction mechanism and a controller connected to the controller.
