An assembled lamp retaining device comprises a lamp seat, a limiting structure
and a lamp rod. In the limiting structure, a pin passes through an upper locking
hole of the lamp seat, a limiting block and a tension spring above the limiting
block so as to confine the limiting block and the tension spring to the lamp seat.
A vertical surface of the limiting block is formed with a through hole and a lower
end thereof is protruded with a buckling sheet. One end of the buckling sheet is
an inclined surface and another end of the buckling sheet is an inclined stepped
surface. The tension spring is between two vertical sides of the limiting block.
Thereby, the limiting block is positioned; and thus, the lamp rod can be assembled
or detached from the lamp seat easily.
