Patent ID: 6918686

Claim:
An assembled lamp retaining device comprising a lamp seat firmly secured to a lateral side of a wire winding box, a limiting structure within the lamp seat and a lamp rod inserted into the lamp seat; wherein a lateral side of the wire winding box has a via hole; and a portion of the lamp seat is coupled to the via hole of the wire winding box for installed a lamp rod; a distal end of the lamp seat is locked with an inserting seat which is exactly resisted by an end portion of the lamp rod; a top of the lamp seat is protruded with a pivotal seat and an upper lock hole and a lower lock hole are formed in upper and lower sides of the pivotal seat; a pin passes through the lower lock hole in advance for retaining the limiting structure; in the limiting structure, a pin passes through the 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 so as to retaining the lamp rod; the tension spring is between two vertical sides of the limiting block; one end of the tension spring is confined above the through hole and another end of the tension spring is confined at a lower end of the pin passing through the lower locking hole of the lamp seat; thereby, the limiting block is positioned; and thus, the lamp rod can be assembled or detached from the lamp seat easily; wherein an end of the slot has a teeth surface for buckling the limiting structure so as to prevent the lamp from falling downwards.
