As shown in fig. 6, the tubular built-in motor 3 is connected to the tube shaft 4 as follows: the tubular built-in motor 3 comprises a main machine head 3-1, a rotating shaft 3-2 and an auxiliary machine head 3-3; the main machine head 3-1 and the auxiliary machine head 3-3 are connected to two ends of the rotating shaft 3-2, the main machine head 3-1 drives the rotating shaft 3-2 to rotate when in use, the auxiliary machine head 3-3 is fixedly connected with the rotating shaft 3-2, and the auxiliary machine head 3-3 can rotate together with the rotating shaft 3-2; the rotating shaft 3-2 is also sleeved with a rotating disc 3-4, and the rotating disc 3-4 can rotate relative to the rotating shaft 3-2; the tubular shaft 4 is of a tubular structure with one closed end, the closed end of the tubular shaft 4 is provided with a follow-up shaft 4-1, the follow-up shaft 4-1 penetrates through a support bearing 4-2 and then is connected with a ratchet 6, the support bearing 4-2 is arranged on a support plate 1-1-1 at the top of a frame body 1-1, the tubular shaft 4 is sleeved on a rotating shaft 3-2 (and is also sleeved on an auxiliary machine head 3-3 and a rotary table 3-4 simultaneously) through the open end, the closed end of the tubular shaft 4 is fixedly connected with the auxiliary machine head 3-3 through a first group of bolts 11, and the open end of the tubular shaft 4 is fixedly connected with the rotary table 3-4 through a second group of bolts 12; when the device is used, the rotating shaft 3-2 drives the auxiliary machine head 3-3 and the rotary table 3-4 to rotate together, and further drives the tubular shaft 4 to rotate together. The main machine head 3-1 is arranged on the headstock 1-1-2 at the top of the frame body 1-1.

As shown in FIG. 3, the tubular shaft 4 is connected to the ratchet 6, the ratchet 6 is engaged with the ratchet 7, and the ratchet 6 and the ratchet 7 form a mechanism for temporarily restricting the reverse rotation of the tubular built-in motor 3.

The upper end of the ratchet 7 is connected with the front end of a transverse pull rod 8 through a front rotating shaft 7-1, the rear end of the transverse pull rod 8 is connected with an unlocking pull rope 9, the unlocking pull rope 9 extends into the sweat steaming room 1, and the transverse pull rod 8 is of a lever structure which can rotate around a fulcrum shaft 8-1 (the fulcrum shaft 8-1 is arranged between the front end and the rear end of the transverse pull rod 8, can be the middle part, can be inclined to the front or the rear and can be selected according to requirements); torsion springs are arranged on the front rotating shaft 7-1 and the fulcrum shaft 8-1.

At normal temperature, especially at low ambient temperature, the blood flow of human muscle is small, the muscle elasticity is poor, the joint mobility is small, and the strain is easy to occur if high-strength traction is directly performed. And body temperature rising, muscle blood flow increases, and the elasticity of muscle and ligament promotes, and tendon and ligament are more soft, and joint activity increases, and at this moment, to the toughness of pulling of joint also can increase, and the range of pulling also can corresponding increase, and the effect of pulling also can be better, reduces the risk of pulling the injury.
