The utility model solves the technological scheme that its technical problem adopts, it comprises frame, motor, T shape tension arms, speed-changing gear box back axle, motor and speed-changing gear box back axle correspondence are fixed in frame, T shape tension arms is rotatably arranged in frame, described motor is provided with driving pulley, and speed-changing gear box back axle is provided with driven pulley; T shape tension arms is provided with rotating V-arrangement Idle wheel peace Idle wheel, strap lug is on driving pulley and driven pulley, between the T shape tension arms of sheet bearing up pulley side and frame, be connected with tensioning extension spring, V-arrangement Idle wheel is from inner side tension belt, and sheet bearing up pulley is from outside tightening belt; Frame is provided with rotating braking pedal, is fixed with linkage board on braking pedal, between linkage board and T shape tension arms, is provided with linkage pull rod.
Described speed-changing gear box back axle is provided with brake arm, is connected with brake retracting spring and brake bar between brake arm and linkage board.
Between described linkage pull rod and T shape tension arms, be provided with linkage rod joint, linkage pull rod is fixedly connected with screw on linkage rod joint by screw thread and passes through its action length of threaded adjusting.
Between described T shape tension arms and frame, be provided with tension arms axle sleeve.
Between described braking pedal and frame, be provided with nylon lining.
Adopt after said structure, there are compared with the prior art following advantage and effect: the one, because V-arrangement Idle wheel is from inner side tension belt, sheet bearing up pulley is from outside tightening belt, between T shape tension arms and frame, be connected with tensioning extension spring, during the work of T shape tension arms, movement range is little, tension effects is good, and working stability is reliable.The 2nd, because the linkage board on braking pedal is connected with T shape tension arms by linkage pull rod, by brake bar, be connected with brake arm with brake retracting spring again simultaneously, braking clutch, to unclamp tensioning transfer speed fast, simple to operate, easy to use.
