Shaftless clamping-force amplification mechanism capable of fast clamping and releasing

Abstract

The invention relates to a shaftless clamping-force amplification mechanism capable of fast clamping and releasing. The shaftless clamping-force amplification mechanism comprises an upper clamping jaw and a lower clamping jaw which are pivoted to each other. Two hook-shaped portions are arranged on the same side of the upper and lower clamping jaws. The other side of the upper clamping jaw is further provided with a buckle fastener interface, and the upper and lower clamping jaws are mutually connected through a shaftless pivot structure. By the shaftless clamping-force amplification mechanism simple in structure and convenient to mount and having good security, operability and social and economic benefits, the defects existed in a background technology are solved; during use, the shaftless clamping-force amplification mechanism can be simply hung on a slide way of an operating bed to realize self-locking by clamping force provided by a buckle fastener, angles of the buckle fastener can be adjusted according to the location of buckling, so that the shaftless clamping-force amplification mechanism cannot fall off voluntarily in case of the buckle fastener is loosened; the buckle fastener is not needed being tensioned when unbinding the same. Besides, by the shaftless pivot structure, the number of parts, cost and assembling complexity can be reduced, and assembling efficiency can be improved.

Description

technical field [0001] The invention relates to a clamping and releasing mechanism, in particular to a clamping force amplification mechanism for fast clamping and releasing without a shaft. Background technique [0002] At present, in the medical field, when a patient needs to undergo an operation, the hospital generally uses a binding strap to restrain the patient's body parts to prevent the patient from causing self-injury during the movement or operation. One end of the bandage used in the existing hospital is fixed on the operating bed, and the other end is equipped with a hook, which is hooked on the side guide rail of the operating bed by the hook, thereby realizing the fixing of the patient. However, in the process of use, it is found that the simple hook has major defects: it is easy to detach from the side guide rail; the angle cannot be adjusted according to the binding position; it is troublesome to loosen the binding strap, and it needs to be pulled with a l...

However, in the process of use, it is found that the simple hook has major defects: it is easy to detach from the side guide rail; the angle cannot be adjusted according to the binding position; it is troublesome to loosen the binding strap, and it needs to be pulled with a large force first Then unhook, causing pain to the patient; when the tension force of the strap is insufficient, it is easy to fall off by itself, causing an accident
