Enough fixed arc buckle (2)；Arc buckle (2) is buckled in the periphery (as a shown in Figure 6) of rotation conductive plate (1), so that
The side facade (1-3) of the periphery two sides of corresponding rotation conductive plate (1) of two arc cant boards (2-2), so that top plate (2-3)
The periphery (1-4) of corresponding rotation conductive plate (1) then makes so that limit pin hole (1-1) is exposed from a hole (2-4)
Mobile sliding block (3-2) is mobile, until U-shaped push piece (4-2) is corresponding limit pin hole (1-1), and U-shaped push piece (4-2) is made to put in limit
In position pin hole (1-1), so that the U-shaped mouth (4-2-1) of U-shaped push piece (4-2) rides in limit pin (1-2), (i.e. limit pin
(1-2) is included in U-shaped mouth) then make U-shaped push piece (4-2) to push the holddown spring (1-6) for limiting the bottom pin (1-2), so
Limit pin (1-2) is taken out out of pin side opening (1-5) afterwards, further take out conductive sub warhead (1-7) and is cleaned and son of polishing
Bullet greasy dirt and scar.
When needing to dismantle next conduction sub warhead (1-7), mobile sliding block (3-2) is pushed, so that U-shaped push piece (4-2) is right
Next limit pin hole (1-1) is answered, then repeatedly aforementioned operation.
Mobile sliding block (3-2) is the arc that radian and arc-shaped slide rail (2-5) are adapted to.
The section of arc-shaped slide rail (2-5) is (as shown in Figure 7) T-shaped structure, the section of mobile sliding block (3-2) be provided with
The adaptable T-shaped hole of the cross sectional shape of arc-shaped slide rail (2-5), T-shaped hole is inserted on arc-shaped slide rail (2-5) from one end when use.Cause
For the cooperation of T-shaped hole and the T-shaped structure of arc-shaped slide rail (2-5), so that mobile sliding block (3-2) will not be from arc-shaped slide rail (2-5)
Fall down, of course for it is mobile it is smooth can between arc-shaped slide rail (2-5) and mobile sliding block (3-2) coating lubricating oil, example
The lubricating oil being such as coated on vehicle dormer window.
The handle (4-3) for facilitating swing rod (4) to push is connected on swing rod (4).
