(2) Description of the Prior Art
Presently traditional cargo transportation operations in general are mostly made through the operation of fastening cargo piling on the truck using ropes and tighten cargo on the hook rods installed on both sides of the frame of the truck. However, to accomplish the operation of fastening cargo, tremendous labor effort has to be made to complete the cargo fastening work. Sometimes, under the situation when the fastening operation is not correct, the cargo might be scattered around and damaged, resulting indirectly in safety problem of worker's injury at work.
Therefore, to ensure the tightness of fastened cargo and reduce the problem of work injury while at the same time provide a strength-saving and practical cargo fastening tool, the industry has developed a product called hand-winder, as illustrated in Taiwan's patent No. 325845. The structural design of such product is mainly consist of a main body and a pulling handle pivoted axially to a hub with a pair of ratchets fixed on the hub to carry together during rotation. A sprawling is used to restrain the ratchet for unidirectional rotation. A flat belt is further wound on the hub so that the hub undergoes unidirectional rotation together with the winding of the flat belt through the up and down pulling control action of the pull handle. The flat belt therefore gradually tightens the cargo in order to achieve the purpose of fastening cargo, and the implementing operation is easier and saving effort.
However, though such hand-winder could improve the labor expense and achieve the result of saving effort in operation as well as reducing the danger in operational safety of fastening operation and increase the convenience, there are also other inconvenience and drawbacks brought with it. The major drawbacks are:
1. A flat belt is required to match with a set of hand-winder for the operation. Therefore, the longer the load on the truck the more hand-winders are needed to prepare. The cost of installing hand-winder the transport business requires to purchase is also relatively increased, which is not really cost effective.
2. Each hand-winder after fastening cargo has to be placed on the fastened cargo and is taken down only after unloading cargo. Therefore, both sides of the truck are hung with arrays of hand-winders. This does not only increase the weight of the truck but also might severely affect traffic safety if the hand-winders drop off due to mechanical failure.
3. Each of the arrays of hand-winders must be kept away after unloading cargo. This therefore creates storage problem if more hand-winders are used, resulting in more trouble and inconvenience and causing severe wastage in work hour.
From the analysis described above, we know that the drawback of such hand-winder is mainly in the hand-winder cannot be removed freely after completion of fastening cargo but has to remain on the cargo. This indeed has the pressing need for improvement.
The main purpose of this invention is to provide a tool for assisting the clamping of rope during the process of tightening cargo and further to achieve the purpose of stretching the rope through the operation of hand-winder in order to resolve the problem of effort spending and safety problem resulted from the traditional pulling labor.
