Brief description
In order to be illustrated more clearly that the present invention, below in conjunction with accompanying drawing, embodiment is briefly described.
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the partial structural diagram of Fig. 1.
Specific embodiment
In order that technological means, creation characteristic, reached purpose and effect that the present invention realizes are easy to understand, below will
In conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely retouched
State.
Referring to Fig. 1-2, this specific embodiment is to employ the following technical solutions to be achieved, and it comprises header body 1, should
The bottom of header body 1 inwardly offers sleeve 2, and its top inwardly offers the guide groove 3 be arrangeding in parallel with sleeve 2, this guide groove 3
The other end vertically extend button cavities 31 upwards, be provided with guide rod 4 in described guide groove 3, one end of this guide rod 4 extends downwardly rising limit
Position block 41, inwardly offers V-shaped groove in the middle part of the bottom surface of this limited block 41, the other end of described guide rod 4 vertically extend upwards by
Button 42, this button 42 is located in button cavities 31, and the bottom surface near middle of described guide groove 3 extends upward boss 32, this boss 32
Upper surface contact with the bottom surface of guide rod 4, be provided with spring 5 between described boss 32 and limited block 41, one end of this spring 5
Withstand on boss 32, its other end withstands on limited block 41, in described sleeve 2, be provided with the contact pin 7 with its grafting cooperation, this is inserted
One circle fixture block 6 is socketed with pin 7, the upper end of described fixture block 6 is located in V-shaped groove, and its lower end is located in stopper slot, and described is spacing
Groove is opened on the bottom surface of sleeve 2.
