Preferably, the outer wall of rear pipe is provided with Anti-slip cover.
Preferably, the head of front pipe is tube head, and tube head external diameter is slightly larger than front pipe external diameter, and outer wall has anti-skid design.
Relative to prior art, beneficial effect of the present invention is as follows:
(1), be automatically locked structure, effectively can alleviate lateral shearing force protection baton intact, improve durability.
(2), spring steel material retaining the intensity of baton simultaneously, add resilient property, effectively increase product service life.
(3), product locking mechanism is ingenious, easy to use, there will not be complete aging stuck state.

Detailed description of the invention
As shown in Figure 1 and Figure 2, self locking expansion baton, comprising: rear pipe 1, middle pipe 3, front pipe 4, be automatically locked buckle 2;
Rear pipe 1 is cylindrical shell, and the outer wall of rear pipe 1 is provided with Anti-slip cover;
Middle pipe 3 is cylindrical shell, and the external diameter of middle pipe 3 is slightly less than the internal diameter of rear pipe 1;
Front pipe 4 is solid cylinder, and the external diameter of front pipe 4 is slightly less than the internal diameter of middle pipe 3; The head of front pipe 4 is tube head 5, and tube head 5 is a part for front pipe, and tube head external diameter is slightly larger than front pipe external diameter, and outer wall has anti-skid design, the convenient twisting when shrinking baton;
Be automatically locked buckle 2, comprising: ejector pin 8, be bi-directionally connected bar 7, bayonet lock 6 and spring, and ejector pin 8, to be bi-directionally connected bar 7, bayonet lock 6 and spring be spring steel material.
Being bi-directionally connected bar is cylindrical shell, is bi-directionally connected the internal diameter of bar and the external diameter tight fit of middle pipe, and be bi-directionally connected the external diameter of bar slightly larger than rear pipe external diameter, be bi-directionally connected bar inwall and be provided with ring body draw-in groove, draw-in groove internal diameter is greater than housing inner diameter;
Bayonet lock is notch cuttype cylindrical shell, bayonet lock leading portion is ejector pin stationary pipes, the external diameter of bayonet lock leading portion closely cooperates with the internal diameter being bi-directionally connected bar, the outer wall of bayonet lock leading portion is provided with positioning through hole, the external diameter of bayonet lock back segment is consistent with the external diameter being bi-directionally connected bar, and the internal diameter of bayonet lock back segment and the external diameter of rear pipe closely cooperate;
The head of ejector pin 8 is cone top cap, middle part is solid cylinder, afterbody is rectangular lock pin, and solid cylinder external diameter is less than top cap basal diameter, and rectangular lock pin afterbody is provided with locating hole, is provided with spring outside lock pin 8, and spring outer diameter is less than cylinder external diameter.
Bayonet lock 6 is located at rear pipe and is bi-directionally connected between bar, and be bi-directionally connected bar 7 and be located between bayonet lock and middle pipe, ejector pin 8 is located at and is bi-directionally connected bar inside, is provided with spring outside the lock pin of ejector pin tail end, and lock pin and spring are connected to pipe place in ejector pin.
Be bi-directionally connected bar inside and have draw-in groove, coordinate bayonet lock effectively to weaken by inner counter elastic force the object that shearing force reaches protection baton when side direction receives shearing force.
In a contracted state, middle pipe 3, front pipe 4, tube head contracting are in rear pipe 1 inside; During use, effective power whipping after holding with a firm grip, middle pipe 3, front pipe 4, tube head can throw away from rear pipe 1, the buckle 2 that is automatically locked between rear pipe 1 with middle pipe 3 is connected, be automatically locked buckle by ejector pin 8, be bi-directionally connected bar 7, bayonet lock 6 and spring and form, the buckle that is automatically locked after throwing away in central Guan Conghou pipe enters locking state, and middle pipe cannot retract in rear pipe voluntarily.Front pipe and tube head therefrom throw away in pipe simultaneously, enter mechanical lock death situation state after front Guan Yuzhong pipe inside has little draw-in groove to throw away.
After throwing away in central Guan Conghou pipe, drive the spring in the middle of ejector pin and bayonet lock by inertia force, moved to by bayonet lock and be bi-directionally connected in the inner spacing draw-in groove of bar, the buckle that is automatically locked enters locking state, and middle pipe cannot retract in rear pipe voluntarily.
Front pipe and tube head therefrom throw away in pipe simultaneously, enter mechanical lock death situation state after front Guan Yuzhong pipe inside has little draw-in groove to throw away.
During retraction baton, first tube head will be rotated, before tube head drives, pipe rotates, and front Guan Yuzhong pipe clamp groove removes locking state, then pushes back in middle pipe with hand by front pipe, push back pipe before in pipe and touch the ejector pin of the buckle that is automatically locked, spring between rationed marketing and bayonet lock rebounds, and buckle removes locking state, continues to exert pressure to tube head, it is inner that namely middle pipe and all part can be recycled to rear pipe, and baton is reduced into original state.
