Description

The present invention relates to a ratchet load tightening machine, and more particularly to a ratchet load tightening machine that can accommodate a belt used for tightening loads.

Non-Patent Document 1 discloses a ratchet load tightening machine in which the fastener used in the load tightening machine is a ratchet type. Ratchet load tighteners are used to prevent cargo from collapsing when it is transported by trucks or trolleys. However, in such conventional ratchet load binding machines, after securing the load, a long belt remains on the winding side. There is a risk that this long belt may become entangled with other luggage, logistics tools, or workers. This may cause an accident or injury to the worker.

Furthermore, a load tightening machine with a belt storage device is disclosed in which, when in use, the belt is pulled out from the storage device, the terminal is hooked, the load is tightened, and the belt is automatically stored in the winder after being released. (See Patent Document 1). However, in such a conventional load tightening machine, it is necessary to provide a belt retracting structure using a spring in the belt storage device, resulting in a complicated structure and making the load tightening machine relatively large, making it difficult to handle.
