Clamping force amplification mechanism for quick clamping and releasing

Abstract

The invention relates to a quick clamping and releasing clamping force amplifying structure which comprises an upper clamping jaw and a lower clamping jaw in pivoted connection. An elastic piece is arranged between the upper clamping jaw and the lower clamping jaw, a bandage connector is connected to the upper clamping jaw, and a through bandage groove is formed in the bandage connector. The quick clamping and releasing clamping force amplifying structure is simple in structure and convenient to use, a bondage can be sleeved on the bandage connector through the bandage groove and an opening, and connection is stable; meanwhile, the bandage can be taken out from the opening quickly; in use, the quick clamping and releasing clamping force amplifying structure is simply hung on a side guide rail of an operating bed, elasticity provided by a flat spring is utilized for achieving clamping, the angle of the bandage can be optionally adjusted according the position of the bandage, the quick clamping and releasing clamping force amplifying structure cannot be disconnected by itself when the bandage is loose, and the bandage needs not to be tensioned when being unbound; the quick clamping and releasing clamping force amplifying structure is good in safety and operability.

Description

technical field [0001] The invention relates to a clamping and releasing mechanism, in particular to a fast clamping and releasing clamping force amplification mechanism. Background technique [0002] At present, in the medical field, when a patient needs to undergo an operation, the hospital generally uses binding straps to restrain the patient's body parts to prevent the patient from causing self-injury during the movement. 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 large force first. Then unhook, causin...
