Abstract: A linked waist support for a waist belt is provided. The waist belt is formed by two strip-like woven fabrics which are connected by a fastening strap, and includes a first end link unit and a second link unit at two ends thereof. The linked waist support is disposed between and partially overlapped by the first end link unit and the second end link unit. The linked waist support comprises a base plate, a first side link unit disposed on the base plate and correspondingly linked to the first end link unit via a first linking cable, and a second side link unit disposed adjacently to the first side link unit on the base plate and correspondingly linked to the second end link unit via a second linking cable. Thus, without unfastening the waist belt, tightening force of the waist belt can be adjusted and changed with ease.

Abstract: A tourniquet includes a first and a second elements and a strap having one end winding around a human body and threading through the first element. The first element has a latch slot and a latch element. The second element has a coupling element at one end latchable with the latch element and the other end fastened to the strap. The first element has an upper and a lower cases and a brake unit inside. The upper and lower cases have respectively an upper and a lower openings threaded through by the strap. The brake unit has a detent edge at one end and an axle at the other end extended to form an actuating member movable with the brake unit about the axle, and an elastic element provides a force for the detent edge to butt the strap from the upper opening to the lower opening.

Abstract: An adjustable tourniquet includes a first component, a second component, a third component and a band. Two ends of the first component respectively have an axle for fixing the band and a buckling trough with an engaging element, wherein two ends of the axle respectively have a ratchet. The first and second components respectively have a rejecting element and a driving element to stop the ratchet. The axle is clamped by an axial cover, and two ends of the axle are respectively connected with a connecting axle for penetrating the second component. Furthermore, the ratchet includes an inner and an outer ratchet surfaces respectively for butting the rejecting element and the driving element, and the teeth of the inner and outer ratchet surfaces are respectively bent toward the same direction and the arrangement of the inner and outer ratchet surfaces are perpendicular to each other.

Abstract: The present invention discloses a pivotal disc is pivotally coupled to a first brace and a second brace. The pivotal disc has a motion-limit member and a positioning member limiting the angle by which the second brace rotates with respect to the first brace with the pivotal disc being the axis and fixing the angle between the first and second braces. The present invention is characterized in that the motion-limit member uses a range-adjust member to push a slide block and determine the range that a block portion of the second brace is blocked by the slide block, and that the positioning member uses a switch knob actuates on end of a positioning rod to engage with or depart from a positioning notch on the pivotal disc, and that the pivotal disc has two limit elements to define the maximum movement range of the first brace and the second brace.

Abstract: A belt structure includes a first housing, a second housing, a third housing and a belt. The two ends of the belt are respectively connected to the first housing and the third housing, which can be buckled together quickly. The second housing and the first housing are connected, so that a mechanism for fine tuning the belt can be formed through the gear, the driving element and the resisting element in the first and the second housing.
