摘要： A strapping device includes two plates and two arms pivotally connected to the two plates by a shaft to which one end of the strap and two ratchets are securely mounted. Each of the arms has a cam device formed thereto and each of the plates has a stop extending therefrom. A short plate is slidably disposed between the two plates and an operating member is slidably disposed between the two arms, both of which are disengagably engaged with the ratchets. A middle member is slidably and biasedly received between the two plates and is slidably connected to a connecting plate between the two plates. Two extending plates are slidably disposed to the two plates and has a rod connected therebetween which is securely connected to the other end of the strap. The rod and the strap move a short distance with the extending plates relative to the plates when rotating the arms to let the cam devices disengage the middle member from the connecting plate and, simultaneously, pulling operating member to let the pawls be disengaged from the ratchets and stopped by the stop. The strap is completely released when the operating member is moved over the stop and the short plate is disengaged from the ratchets by the cam devices.

摘要： A strap-tensioning apparatus includes a frame, a handle, a reel, two ratcheted wheels, two detents and a strap-damping unit. The handle is connected to the frame. The reel is supported on the frame. The ratcheted wheels are secured to the reel. The strap is inserted through a slit of the reel. The first detent is supported on the handle for engagement with the ratcheted wheels to rotate the reel when the handle is pivoted in a direction. The second detent is supported on the frame for engagement with the ratcheted wheels to stop the reel when the handle is pivoted in an opposite direction. The strap-damping unit includes a crossbar, a pressing element and a spring. The crossbar is supported on the frame. The pressing element is biased toward the crossbar by a spring. The strap is inserted through a gap between the pressing element and the crossbar.
