Description

Multifunctional bolting device and use method thereof Technical Field The invention relates to a tightener, in particular to a multifunctional tightener, and belongs to the technical field of tighteners. Background In each transportation field such as boats and ships, freight train, need use the stopper to fix the goods that are in when transporting, remove, loading and unloading or storage, especially inside the boats and ships, need a large amount of stopper that use, fix one end on the anchor seat of elevator or transfer car, the other end is fixed on the fixed part of goods, prevents to cause the goods to empty or the landing because of the boats and ships sways in the navigation. The current latch in the industry has the following problems: (1) Because the transportation of a large amount of cargoes in the ship is required to be frequently fastened and unfastened by the fastening devices, a plurality of fastening devices are sometimes required to be used for each cargo, the existing fastening devices are mostly ratchet drive sleeves, so that the binding belt is gradually unfastened or tightened, and a large amount of time is wasted in the use process; (2) The existing binding belt of the tightener needs manual recovery, can not realize quick recovery, and wastes time in the use process. (3) The existing tightener cannot realize multiple functions such as unidirectional extension, unidirectional contraction, bidirectional extension contraction or locking of the braid, can not be operated by one hand, and has low use convenience.
