For example, when the intermittent lumbar traction apparatus is used, the intermittent lumbar traction apparatus is firstly seated on the cushion and leaned against the cushion, the traction member is fixed on the waist of the patient, then the patient steps on the pedal structure to drive the driving sprocket, the driving sprocket drives the driven sprocket to rotate through the chain, and finally the traction member rises to implement traction operation. When the sleeve reaches the polished rod section, the traction piece is not lifted, and after a period of time, the patient lifts and aligns the sleeve with the upper threaded section to thread the sleeve with the upper threaded section. Then, when the pedal structure is seated and pedaled again, the traction piece is lifted continuously, so that the gap traction is implemented to adapt to the traction operation of different stages. Because intermittent type nature lumbar vertebra tractor has adopted trampling the structure, consequently can utilize the great strength of foot to trample, make the manipulation of intermittent type nature lumbar vertebra tractor equipment is comparatively convenient.

For example, in order to guide the lifting of the sleeve, the screw rod is rotatably disposed at one side of the backrest cushion, a guide rod 15 is protruded at one side of the support body, and the sleeve is connected to the guide rod in a rotation-stopping manner. The guide rod is concavely provided with a limiting slot 151, the end part of the sleeve is convexly provided with a limiting strip 331, and the limiting strip is convexly arranged in the limiting slot. The guide rod and the screw rod are arranged in parallel at intervals, and the width of the guide rod is larger than the diameter of the screw rod. The end part of the limiting strip is provided with a sliding cushion block which is supported against the bottom surface of the limiting slot in a sliding manner. The back cushion epirelief is equipped with a plurality of fixed poles, a plurality of fixed poles towards the protruding establishment of one side of cushion. The guide rod is arranged on one side of the support body, so that the rotation of the sleeve can be limited, and the lifting of the sleeve is guided.

For example, in order to facilitate the conversion of the stepping motion into the lifting motion of the sleeve, the diameter of the first bevel gear is smaller than the diameter of the second bevel gear, and the axial direction of the second bevel gear is perpendicular to the ground. The diameter of the driving sprocket is larger than that of the driven sprocket. The pedal structure comprises a linkage frame and two pedals, the linkage frame is fixedly arranged in the driving chain wheel in a penetrating mode, and the two pedals are respectively arranged on two opposite sides of the driving chain wheel. The pedal is rectangular plate-shaped, and a plurality of strip-shaped hollow grooves are formed in the pedal. The diameter of the driving chain wheel is set to be larger than that of the driven chain wheel, so that the driving chain wheel can drive the driven chain wheel to rotate at a larger transmission ratio, and then the treading movement is conveniently changed into the lifting movement of the sleeve.

For example, and with particular importance to fig. 2, to facilitate stretching of the neck, the sleeve is provided with a neck assembly 40 comprising a pull rod 41 disposed on the sleeve and a pull ring 43 disposed on top of the pull rod, the pull ring having an access opening 411 formed in one side thereof for the neck of the patient to be inserted into the pull ring. Owing to be provided with neck subassembly, consequently when the patient is carrying out the self-traction and drawing to the lumbar vertebrae, can utilize the pull ring carries out the self-traction and drawing to the neck to realize the efficiency of killing two birds with one stone. For example, the traction rod is arranged obliquely relative to the screw rod, and the traction rod is inclined towards one side of the cushion. By arranging the traction rod to be inclined, the traction rod can be used for pushing the shoulders of the patient to move and deflect, so that the traction effect is improved. For example, the plane of the traction ring is perpendicular to the extension direction of the traction rod.

For example, in order to facilitate adjustment of the angle of inclination of the traction ring with respect to the traction bar, the traction ring is pivotally mounted on the top of the traction bar via a pivot assembly 50, and the pivot assembly is configured to adjust the angle of rotation of the traction ring with respect to the traction bar, thereby accommodating traction of the patient's neck from different angles. For example, the rotating assembly includes a rotating cylinder 51 rotatably disposed on the drawbar, an operating ring disposed at an end of the rotating cylinder, a central axis of the rotating cylinder being on a plane of the operating ring, and a plurality of insertion holes 511 disposed around a circumference of the rotating cylinder. The inserting rod is fixed on the traction ring, two opposite ends of the elastic piece are respectively connected with the traction ring and the traction rod, so that the traction ring is pulled to move towards the traction rod, the elastic piece drives the inserting rod to be inserted into the inserting hole, and the inserting rod is utilized to position and support the traction ring. For example, a plurality of fixed rods 515 are convexly arranged on one side of the rotating cylinder, the fixed rods are arranged around the rotating cylinder, a fixed groove is arranged on one side of the traction rod, one of the fixed rods is clamped into the fixed groove, so that the rotating cylinder is positioned, the rotating cylinder cannot rotate relative to the traction rod, the insertion rod is pulled to be separated from the insertion hole by overcoming the elastic force of the elastic piece, then the operation ring is pulled longitudinally, the fixed rod is separated from the fixed groove, the rotating cylinder is rotated to align the other fixed rod with the fixed groove, then the rotating cylinder is pushed longitudinally to return to enable the fixed rod to be clamped into the fixed groove, and then the insertion rod is inserted into the other adjacent insertion hole, so that the traction ring can be positioned at different angles relative to the traction rod. For example, the number of the fixed rods is 12, namely, each fixed rod rotates by 30 degrees. For example, the insertion holes are 24, that is, the pulling ring is rotated by 15 degrees every time the pulling ring is inserted into an adjacent insertion hole. For example, in order to increase the fineness of adjustment, the plurality of fixed rods and the plurality of insertion holes are staggered with each other, that is, the plurality of fixed rods and the plurality of insertion holes are not all on the same axis of the peripheral surface of the rotary cylinder.

For example, in order to improve the self-return performance of the traction ring, the elastic member includes two elastic holding strips, which are respectively connected to opposite sides of the traction rod. The opposite two ends of each elastic pulling and holding strip are respectively connected with the traction rod and the traction ring, and the two elastic pulling and holding strips are symmetrical, so that the traction ring is uniformly stressed and can automatically return, and the insertion rod can be automatically inserted into the insertion hole. For example, in order to avoid that the fixed rod is separated from the fixed groove at will, one end of the rotating cylinder, which is far away from the operating ring, is further provided with a return spring, and two opposite ends of the return spring are respectively connected with the rotating cylinder and the traction rod, so that the rotating cylinder is pulled and held by the return spring, and the fixed rod on the rotating cylinder is not easy to separate from the fixed groove on the traction rod. For example, the rotation axis of the rotary cylinder is perpendicular to the length direction of the traction bar.
