Instantaneous firing self-locking type anti-riot fork

Abstract

The invention discloses an instantaneous firing self-locking anti-riot fork which comprises a grip, a linkage mechanism is arranged at the front end of the grip and comprises a fixed hinge seat, a fork head shell, a guide square sleeve, an axial clamping rod, an axial push rod, a driving guide strip, a hinge shaft, a guide shaft A, a spring A and a steering seat, wherein the fixed hinge seat is coaxially and fixedly connected to the front end of the grip. Through a structural design mode of setting dead point locking, the anti-riot fork has a stable to-be-excited state and an instantaneous excitation state, the quick excitation closing effect can be achieved through instantaneous recovery after elastic deformation of a spring, and meanwhile, an anti-riot fork rod is opened and closed through a clamping dead point state of a front half section groove of a sliding groove B to the guide shaft A, the guide shaft A cannot be reversely pushed to move backwards through the sliding groove B, the situation that the anti-riot fork rod needs the self-locking characteristic in the closed state is ensured, a riot donor cannot open the anti-riot fork rod by breaking off the anti-riot fork rod outwards, so that the effect of completely controlling the riot donor can be achieved.

Description

technical field [0001] The invention relates to the technical field of social security, in particular to an instantaneous firing self-locking anti-riot fork. Background technique [0002] At present, a variety of police equipment is widely used in riot control and security fields, such as batons, rubber sticks, net shooting devices and police forks, etc. Although these equipment have taken certain preventive measures, they have had little effect. Anti-riot catching forks are widely used in anti-riot and security fields. The long length of anti-riot catching forks can enable security personnel to deal with dangerous people with weapons more safely. At the same time, anti-riot catching forks are also relatively safe devices that can prevent injuries during riot to dangerous persons. At present, tools such as anti-riot forks are used in the market to control and subdue dangerous people, but in the actual use process, it is known that the existing anti-riot forks have the follo...

AI Technical Summary

Problems solved by technology

[0003]1. Most anti-riot forks do not have the ability to open and close, and cannot quickly and effectively subdue criminals. Most anti-riot forks have large forks, but cannot Opening and closing the shrinking harness for the perpetrator, the fork of a few anti-riot forks has the function of shrinking the harness, but due to the limitations of the structural design, the fork is too small and cannot be retracted, so it cannot be used to restrain the neck and waist of the assailant. The slender limbs of the perpetrator are contracted and clamped, and the success rate is low

[0004]2. The existing anti-riot fork device continuously pushes the ratchet lock through the arc rod inside the fork. Self-initiated contraction requires a large push stroke to ensure the continuous contraction of the internal ratchet bar. Only when the push is reached to the maximum stroke can the internal ratchet bar of the bayonet shrink to the minimum state. Unable to form maximum harness, resulting in low success rate of existing anti-riot fork harnesses
