Clamping force increasing mechanism capable of quickly clamping and releasing

Abstract

The invention relates to a clamping force increasing mechanism capable of quickly clamping and releasing. The clamping force increasing mechanism is characterized by comprising an upper clamping claw and a lower clamping claw which are connected via a pivot; the surface on one side of the upper clamping claw as well as that on the same side of the lower clamping claw is provided with a hook-shaped part; a binding band connector is arranged on the surface on the other side of the upper clamping claw; a long through binding band groove is formed in the binding band connector. The clamping force increasing mechanism overcomes the defects in the background technology, is simple in structure and convenient to mount, is only simply hung on a guide rail on an operating table during application, realizes self-locking by utilizing tension provided by a binding band, can achieve regulation of the angle of the binding band according to the position of the binding band, cannot automatically fall off when the binding band is in a released state, does not need to strain the binding band when the binding band is released, and has good safety, operability, and social and economic benefits.

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, ca...
