Preparation process:

1, main expansion link, be that mobile jib is a cavity structure, bar is long to be formulated as required, and a fairlead is left in pole top on the about 300mm in top place bar wall, establish a pipe plug in the following cavity of fairlead, making two U-shaped bars and pass through the hole on the pipe plug with on the diameter of fairlead horizontal axis vertical direction.

2, flexible internal core rod is the hollow cylinder Collapsible structure, and the lower end is provided with flush ring.

3, U-shaped bar, its body of rod two posts upper end is provided with the silk hole that U-shaped bar set screw is installed.The length sum and the mobile jib of internal core rod and U-shaped bar are suitable.

4, T-shaped crossbeam, its crossbeam are flat rectangular structure, and two ends respectively have one to wear the aperture that U-shaped bar set screw is used, and its T-shaped pin is a column structure, is positioned in the middle of the crossbeam.

5, ignition controller comprises controller housing and inner sparking push rod, lighter, clamp hole and ceramic line ball folder thereof.

6, ignition controller shell, it is a cavity cylinder, but be provided with the bottom of folding, it just, the back side is the plane, and the and arranged on left and right sides face is a cambered surface, and two cambered surfaces and mobile jib inwall match, the end face center of controller housing is provided with the circular hole that the T-shaped of holding T-shaped crossbeam was worn, one side cambered surface is provided with the firecrackers fairlead, and the fairlead on this hole and the mobile jib matches, and positive lower right is provided with the lighter holding screw.

7, sparking push rod, be anti-italic T shape structure, the end face shape is consistent with the cross section of controller housing, and the top center position is provided with the groove of the T-shaped pin insertion of holding T-shaped crossbeam, groove floor has an elongate rod that tilts to the lower right, and non-skid feet is equipped with in the elongate rod lower end.The sparking push rod places in the controller housing, and the upper surface of sparking push rod is near the controller housing end face, and the circular hole of the groove at top and controller housing end face matches.

8, clamp hole and ceramic line ball folder, the clamp hole is positioned at the position of intersecting point of the horizontal axis of the vertical central axis of ignition controller shell and firecrackers fairlead, and be fixed on the inwall of ignition controller shell, described ceramic line ball folder suppresses outer surface in the clamp hole with spring.

9, lighter is common gases lighter commonly used, places bottom in the controller housing, and the sparking button withstands on the non-skid feet of sparking push rod lower end, and fire output hole is facing to the ceramic line ball folder of top.

10, upper and lower end socket, upper cover is provided with the hook that the big gun of ending a teaching or coaching career is used, and is threaded onto the mobile jib upper end in the upper cover; The center of low head is provided with and holds the circular hole that internal core rod is passed, and the circular hole next door is provided with the draw ring locking device, and low head is threaded onto the mobile jib lower end outward.

During actual the use, the concrete operations step is as follows:

1. pole is stretched out, unload the upper cover of lower rhabd upper end, unclamp the set screw that connects T-shaped crossbeam and U-shaped bar, T-shaped crossbeam is removed from the ignition controller top, in the mobile jib cavity, take out ignition controller then.

2. open the bottom of ignition controller shell, the fire output hole of lighter is aimed at firecrackers fairlead and ceramic line ball folder, the non-skid feet of sparking button aligning sparking push rod lower end is packed in the controller, close the then bottom of controller housing screws the bottom-right lighter holding screw of controller housing again.

3. the fairlead on the controller is aimed at the fairlead on the mobile jib, pipe plug top in the mobile jib upper cavity of packing in the middle of mobile jib top, U-shaped bar two roofbolts makes the positioner on pipe plug and the controller contact-making surface identical.

4. the circular hole of the T-shaped of T-shaped crossbeam being worn on the controller housing top cover inserts in the groove of sparking push rod upper end, respectively the two ends of T-shaped crossbeam are connected the two posts upper end of U-shaped bar with two U-shaped bar set screw, adjust U-shaped bar set screw and make the T-shaped pin of T-shaped crossbeam compress the sparking push rod.

5. upper cover is installed.

6. firecrackers hanging wire end is hung on the hook of upper cover; get the long core that draws of 1～2 of the firecrackers other end and be pressed in the clamp hole;; the line ball cramping tightly draws core when having any problem; firecrackers partly can be wrapped in mobile jib top, to alleviate the pulling that firecrackers press from both sides line ball if firecrackers are long heavier with ceramic line ball folder.

7. pole is lifted, open the draw ring locking device on the mobile jib low head, both hands are held up bar, finger hooks flush ring and firmly one draws, draw ring drive internal core rod, U-shaped bar, T-shaped crossbeam, sparking push rod move down together, the sparking push rod is to the sparking button of lower compression lighter, thereby makes the lighter igniting.Because firecrackers draw the fire output hole top process of core from lighter, the core that draws that part is lacked a bit slightly is positioned at the flare top just, these draw core and are at first lighted, and moment blow by what the line ball cramping was lived and draw core, because the gravity effect of firecrackers itself makes firecrackers one end of being lighted hightail the body of rod and aloft explodes.
