[0002] The knee is a part of the human body that is located at the connection between the upper and lower legs. The main internal components of the knee are the meniscus and four ligaments. In rehabilitation therapy, for conservative treatment of knee joint and soft tissue or ligament injuries, postoperative external fixation, and prevention and treatment of knee spasm, auxiliary devices such as knee fixators are often evaluated to stabilize and protect the knee joint, relieve some of the load on the knee joint, reduce pain and promote lesion healing, correct or prevent further development of deformities, and maintain knee joint movement and load-bearing function.

[0003] A knee fixer with a correction function disclosed in the Chinese utility model patent application disclosure CN 217488991 U allows users to select and add a connecting belt, but when limiting the position of bolt 1, the user can only limit and fix the knob block by rotating bolt 2 clockwise so that one end of the bolt 2 abuts against the slot at the top of the knob block. The operation is not convenient enough, so there is a problem that the position limiting of the knob block is not convenient enough. In addition, during the movement of the user, since the slider is not restricted, the plate body that is not restricted by bolt 1 is prone to shaking and generating noise, which affects the user. Therefore, there is a problem that the plate body is prone to shaking and generating noise. In summary, the utility model has the problems that the position limiting of the knob block is not convenient enough and the plate body is prone to shaking and generating noise.
