Clamping force amplification mechanism for clamping and releasing

Abstract

The invention relates to a clamping force increasing mechanism of clamping and releasing. The clamping force increasing mechanism comprises an upper clamping claw and a lower clamping claw, which are connected via a pivot, wherein the side surfaces on the same side of the upper clamping claw and the lower clamping claw are both provided with hook-shaped parts. The clamping force increasing mechanism is characterized by further comprising a limiting mechanism for limiting the upper clamping claw and the lower clamping claw to rotate around the pivot between the two clamping claws. 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 in the state of releasing the binding band, does not need to strain the binding band when the biding band is released, and has good safety, simplicity in operability, social benefit and economic benefit.

Description

technical field [0001] The invention relates to a clamping and releasing mechanism, in particular to a 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, causing pai...
