[0039] In one specific embodiment, at least two of the aforementioned traction devices 3 are included, each of the aforementioned traction devices 3 being disposed on the support rod 2.

[0040] In practical applications, two traction devices 3 are usually set. In specific use, one or two may be used. For example, when traction is needed for one of the patient's ankles, one traction device 3 is sufficient. When traction is needed for both of the patient's ankles, both traction devices 3 need to be used.

[0041] In one specific embodiment, the first adjuster includes: a first adjusting block 12, a second adjusting block 13, and a locking member 4; the connecting rod 6 is fixedly connected to the first adjusting block 12, and the second adjusting block 13 is fixedly connected to the end of the adjusting rod 8; a plurality of protrusions 15 are provided on the end face of the first adjusting block 12; a plurality of slots 16 are provided on the end face of the second adjusting block 13; the protrusions 15 are adapted to engage with the slots 16; the locking member 4 passes through the first adjusting block 12 and is threadedly connected to the second adjusting block 13; the locking member 4 is used to lock the first adjusting block 12 and the second adjusting block 13; changing the engagement position of the protrusions 15 and the slots 16 and locking them is used to adjust the included angle between the connecting rod 6 and the adjusting rod 8.

[0042] In this embodiment, see Figure 3 , Figure 4 As shown, a plurality of protrusions 15 are provided on the end face of the first adjusting block 12, and a plurality of slots 16 are provided on the end face of the second adjusting block 13. The number and position of the protrusions 15 and the slots 16 are in one-to-one correspondence, and the size of the protrusions 15 and the size of the slots 16 are also matched with each other. That is, all the protrusions 15 can be inserted into the slots 16 one-to-one. Then, the locking member 4 is used to lock the first adjusting block 12 and the second adjusting block 13.

[0043] In one specific embodiment, the second adjuster includes: a third adjusting block 17, a fourth adjusting block 18, and a locking rod 1; the adjusting rod 18 is fixedly connected to the third adjusting block 17, and the fourth adjusting block 18 is fixedly connected to the side wall of the outer casing; a plurality of protrusions 15 are provided on the end face of the third adjusting block 17; a plurality of slots 16 are provided on the end face of the fourth adjusting block; the protrusions 15 are adapted to engage with the slots 16; the locking rod 1 passes through the third adjusting block 17 and is threadedly connected to the fourth adjusting block 18; the locking rod 1 is used to lock the third adjusting block 17 and the fourth adjusting block 18; changing the engagement position of the protrusions 15 and the slots 16 and locking them is used to adjust the included angle between the adjusting rod 18 and the outer casing.

[0044] In this embodiment, the assembly distance between the third adjusting block 17 and the fourth adjusting block 18 is the same as the adjustment distance between the first adjusting block 12 and the second adjusting block 13 described above. During the locking process, the third adjusting block 17 and the fourth adjusting block 18 are locked together by screwing on the locking rod 1.

[0045] It is understandable that the locking rod 1 passes through the third adjusting block 17 and is threadedly connected to the fourth adjusting block 18. The threaded hole in the fourth adjusting block 18 is relatively deep. When the locking rod 1 is threadedly locked, there is still a certain distance between the end of the locking rod 1 and the bottom of the threaded hole. In this way, motion interference is avoided when the locking rod 1 locks the third adjusting block 17 and the fourth adjusting block 18.

[0046] The locking principle of locking component 4 is the same as that of locking rod 1.

[0047] In one specific embodiment, the fixing device 5 is an annular clamp, and the support rod 2 is fixed in a predetermined position by the annular clamp. One end of the connecting rod 6 is connected to the support rod 2 by a changeable clamp.

[0048] A ring clamp is a structure that can be locked and fixed to a columnar object. In this application, the ring clamp can be adopted as follows: Figure 6 The clamp shown is shown. In practical applications, the support rod in this application can be connected to the ring clamp using common fixing methods, such as welding or using a sleeve. For example, when using a sleeve, a middle ring is set on the side of the ring clamp, and the ring is sleeved on the outer wall of the support rod. If you want to fix it, you can use a bolt to pass through the ring to achieve threaded tightening, or other methods can be used. This application does not limit the method.

[0049] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
