Shark driving wrist guard for underwater emergency risk avoiding

Abstract

The invention discloses a shark driving wrist guard for underwater emergency risk avoiding, and relates to the technical field of underwater risk avoiding. The shark driving wrist guard for underwater emergency danger avoiding comprises a bracelet, a fixing box is fixedly connected to the upper surface of the bracelet, a blocking piece is fixedly connected to the front side of the fixing box, a gas generating mechanism is arranged on the side portion of the fixing box, and a first spring is fixedly connected to the rear side of the inner wall of the fixing box; the front end of the first spring is fixedly connected with a blade, the upper surface of the blade is fixedly connected with a top block, and the outer wall of the blade is slidably connected with the inner wall of the fixed box. According to the shark driving wrist guard for underwater emergency danger avoiding, when the blade extends out, air rushes into the sliding cavity through the air pipe, so that the ejector rod ascends to lift the first limiting block, the first limiting block does not limit the second spring any more, the wing plate is bounced off by the second spring, the wing plate is opened to enable swimming and turning to be more convenient, and underwater fighting with a shark is more facilitated.

Description

technical field [0001] The invention relates to the technical field of underwater danger avoidance, in particular to a shark repelling wrist guard for underwater emergency avoidance. Background technique [0002] Some adventure enthusiasts like to dive in the shallow sea or in the sea, and when a shipwreck occurs, people need to float in the water and wait for rescue.
