Connecting plate is connected by the first screw.
By using above-mentioned technical proposal, the connecting plate of strut end is connect with connecting seat by the first screw, and connection is made
Seat is replaceable.
Further, the connecting seat is equipped with limit hole, and the grafting block is equipped with matches limit with the limit hole
Position block, the grafting block are connect with the connecting seat by the second screw.
By using above-mentioned technical proposal, limited block coordinates with limit hole, plays the role of being set to grafting block, and limit
Block passes through the bottom of limit hole that can be electrically connected with electric wire, and grafting block is connect with the connecting seat by the second screw, and grafting block is made
It is replaceable.
Further, the grafting block is set there are two slot, and the slot extends along the direction far from grafting block center, institute
It includes two pins, the pin and the slot grafting to state light bulb.
By using above-mentioned technical proposal, the different light bulb of the pluggable pin spacing of two slots.
Further, the wire casing bottom wall of the strut end is equipped with jack, and the electric wire passes through jack and the limited block
Bottom is electrically connected.
By using above-mentioned technical proposal, electric wire is electrically connected across jack with limited block bottom, be can avoid electric wire and is stopped lamp
The light of bubble causes light projection uneven.
Further, it is arranged with cooling fin on the pin.
By using above-mentioned technical proposal, cooling fin can help pin to radiate, and reduce pin temperature.
Further, the strut end is bundled with band.
By using above-mentioned technical proposal, electric wire can be limited in wire casing by band.
Further, the grafting block is ceramic grafting block.
By using above-mentioned technical proposal, ceramics have preferable heat resistance and insulating properties, can avoid grafting block and are become by heat
Shape and conduction.
In conclusion the utility model has the advantages that：Strut stretches into light bulb in viewing ball, so as to make lamp
Bubble is placed in projection ball center, and strut is fixed by pedestal；When needing to be adjusted light bulb or replace, only need to draw
Dynamic pedestal extracts strut out out of viewing ball.
