Integrated brake structure and tensioner

An integrated brake structure, comprising a housing (1), a ratchet wheel (2), a handle holder (3), and a brake pad assembly, wherein the ratchet wheel (2) is rotatably arranged on the housing (1), a first bandage (5) is wrapped around the ratchet wheel (2), the handle holder (3) is movably arranged on the housing (1) and has a locked position and an unlocked position during movement, the brake pad assembly comprises a first brake pad (61), a second brake pad (62), and an elastic member (63), the first brake pad (61) is connected to the handle holder (3), the second brake pad (62) is connected to the first brake pad (61);

• when the handle holder (3) is driven to the locked position with an external force, the elastic member (63) drives the first brake pad (61) to abut against and lock the ratchet wheel (2) to restrict the first bandage (5) from being pulled out by the external force;
• and when the handle holder (3) is driven to the unlocked position with the external force, the elastic member (63) drives the second brake pad (62) to abut against the ratchet wheel (2) and position the ratchet wheel (2) in a semi-locked state, at which moment the first bandage (5) can be pulled out by the external force;
• wherein the first brake pad (61) is provided with a pressing handle (614), the second brake pad (62) is pressed against one side of the first brake pad (61) away from the ratchet wheel (2), the elastic member (63) is a torsion spring, and two legs of the torsion spring abut against the handle holder (3) and the first brake pad (61) respectively;
• and
• wherein the torsion spring is provided with a limiting protrusion (631) in a bending manner, the first brake pad (61) is provided with a first limiting groove (615) corresponding to the limiting protrusion (631), the second brake pad (62) is provided with a second limiting groove (623) corresponding to the limiting protrusion (631), and the limiting protrusion (631) is clamped in the first limiting groove (615) and the second limiting groove (623) simultaneously for limiting the position.
