Portable spontoon-type tyre breaking device

Abstract

The invention discloses a portable spontoon-type tyre breaking device, which comprises a rigid sleeve, an inner supporting core and a handle, wherein multiple groups of troughs are arranged along the axial direction of the rigid sleeve, and each group of troughs comprises a plurality of troughs which are arranged along the circumference of the rigid sleeve; the inner supporting core is sheathed by the rigid sleeve; the inner supporting core comprises a rotation shaft and multiple groups of barbed nail devices which are movably installed on the rotation shaft along the axial direction; each group of barbed nail device comprises a plurality of barbed nail devices which are arranged along the axial direction of the rotation shaft; the barbed nail devices and the troughs on the rigid sleeve are correspondingly arranged; each barbed nail device comprises a barbed nail and a connection part; one end of the connection part is movably connected with the rotation shaft; the barbed nail is installed on the other end of the connection part; the handle is clamped and installed on one end of the rigid sleeve and can rotate relative to the rigid sleeve; the handle is provided with a control button; one end of the rotation shaft is movably cooperated with the rigid sleeve, and the other end of the rotation shaft is cooperated with the control button on the handle through a connection control mechanism.

Description

technical field [0001] The invention relates to a multi-functional equipment for police protection and vehicle blocking, in particular to a portable lightweight multifunctional tire breaker made of carbon fiber hybrid composite material, which can be used as a baton and a tire breaker respectively. Background technique [0002] At present, with the continuous development of vehicle traffic, dangerous accidents based on vehicles are also on the rise, such as drunk driving accidents, hit and run, driving crimes and so on. To deal with such problems, police officers, anti-riot personnel, and security personnel usually carry certain vehicle braking equipment when performing tasks. The handling of emergencies requires instantaneous completion of crime prevention and vehicle braking tasks. At this time, large-volume braking equipment is often very inconvenient to carry. [0003] The traditional tire breaker adopts an aluminum alloy folding bracket, and a triangular zinc-aluminum ...

Problems solved by technology

The handling of emergencies requires instantaneous completion of crime prevention and vehicle braking tasks. At this time, large-volume braking equipment is often very inconvenient to carry

[0003] The traditional tire breaker adopts an aluminum alloy folding bracket, and a triangular zinc-aluminum alloy needle is mounted on it. The material is all metal, and the length is 5 meters, 8 meters, 10 meters, etc. The volume of the tire breaker is relatively large, and the metal has a relatively large body density. And the more complex connection structure brings greater deadweight, and it is extremely inconvenient to carry alone

[0004] Although a kind of anti-riot baton with a tire breaker has been disclosed, the tire breaker device is installed inside the stick body. When starting the tire breaker, the tire breaker is pushed out of the stick body by an elastic push mechanism. At the top of the stick body, the effective tire breaking length is short, and the stick body is not an effective tire breaking part. When the tire breaker pushes out the stick body, the length o
