Adjustable body brace and adjusting assembly thereof

An adjustable body brace comprising:

• an adjusting assembly having:
• a base having a length direction and a thickness direction, and the base including:
• a first surface;
• a limit groove recessed from the first surface along the thickness direction and extending along the length direction;
• and
• two wall surfaces respectively located on two opposite lateral sides of the limit groove, and each one of the two wall surfaces extending along the length direction;
• a slider movably mounted on the base, and movable with respect to the base along the length direction;
• a fixing module connected to the slider and mounted in the limit groove, and the fixing module having a locked state and an unlocked state;
• the fixing module including:
• an engaging unit movable along the thickness direction and having:
• an engaging portion selectively located in the limit groove;
• wherein, when the fixing module is under the locked state, the engaging portion is in the limit groove and engages with the two wall surfaces, and thereby a position of the slider with respect to the base is fixed;
• when the fixing module is under the unlocked state, the engaging portion is out of the limit groove, thereby the slider being movable with respect to the base along the length direction;
• wherein, the fixing module further includes an elastic unit connected to the engaging unit, and the elastic unit capable of driving the engaging unit to move along the thickness direction;
• wherein, another surface opposite to the first surface of the base is a second surface, and the limit groove penetrates the second surface along the thickness direction;
• and
• the elastic unit is connected to an end of the engaging unit, and the elastic unit is located out of the limit groove;
• the elastic unit further has at least one wing portion, the at least one wing portion abuts the second surface, thereby the engaging unit tending to move out from the limit groove;
• wherein, the fixing module further includes a knob rotatably sleeved on the engaging unit and abutting the slider;
• the knob having:
• an oblique surface located on a surface of the knob, and said surface away from the slider, and the oblique surface being oblique along a rotating direction of the knob;
• an abutting unit connected to another end of the engaging unit, said end opposite to the elastic unit, and the abutting unit abutting the oblique surface and slidable with respect to the oblique surface;
• and
• an outer groove recessed from an outer annular surface of the knob, and the outer groove extending along a circumferential direction of the knob and having two opposite ends;
• the slider further has a protrusion located in the outer groove;
• and
• when the fixing module is under the locked state or the unlocked state, the protrusion is located at either one of the two opposite ends of the outer groove;
• and
• two board units respectively connected to the base and the slider.
