A binding belt tensioner is provided, it relates to a ratchet type binding tool, and its structure includes a fastener, a wrenching part, a ratchet, a fixing binding belt and a tensioning binding belt, etc. Mainly, the ratchet shaft of the racket for winding the tensioning binding belt is provided with a coil spring and a coil spring locking mechanism which are coaxially mounted; when the ratchet shaft rotates for belt outputting, the coil spring can be driven synchronously to wind and compress the ratchet shaft to form elastic potential energy, and the elastic potential energy of the coil spring is locked by the coil spring locking mechanism; when the coil spring locking mechanism is operated to release the elastic potential energy of the coil spring, then the ratchet shaft is driven to automatically quickly rewind the tensioning binding belt for use of the binding belt tensioner next time. Therefore, by additionally disposing the coil spring and the coil spring locking mechanism on the ratchet shaft, while the fast and reliable binding of the goods by the binding belt tensioner is not affected, the binding belt tensioner has the advantages of portability in belt collecting, labor saving in operation and the like, such that the loading and unloading efficiency of the goods is improved and loading and unloading of the goods become simpler and ordered.
