Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.

Referring to Fig. 1 and Fig. 2, the lamp holder that the utility model provides comprises main body 1, connector 2 and electricity-saving lamp socket 3.Connector 2 is formed on an end (upper end) of main body 1, its can be connected with the screw lamp holder (not shown) of common bulb (directly can screw in); The plug that electricity-saving lamp jack part 3 can hold the electricity-saving lamp connector inserts, and it is the end (lower end) in main body 1, and two sockets are arranged.Certainly, according to different power saving fluorescent lamps (whether containing control circuit), also can be a socket, the quantity of socket, inserted mode and relative dimensions are decided according to relevant standard.

Be provided with an opening 22 in the side of connector 2, be provided with a fixture block 21 in opening 22, it can prevent that connector from oppositely spinning out (below will describe in detail) from screw lamp holder.

Referring to Fig. 3, in opening 22, be provided with a little space, the fixture block 21 of strip is arranged in this space.One end of fixture block 21 interconnects by the fixture in a fixed rotating shaft 213 and the opening, and like this, this fixture block 21 can rotate around this rotating shaft 213.One spring 212 is arranged on the left side of fixture block 21, and the one end is placed in the recess C (moving freely preventing) in vertical plane, and the other end contacts with the middle part of fixture block 21.Right part at fixture block 21 is provided with a projection 214, and when fixture block 21 during near upright position (position shown in the figure), fixture block 21 is close with projection 214.At this moment, the elastic force of spring 212 can make fixture block 21 when connector 2 does not screw in screw lamp holder, is in as the position among Fig. 4, keeps the part of dop D to expose outside the opening 22 of side of connector 2.

When the direction (counter-clockwise direction) that screws according to illustrated forward when connector 2 screwed in screw lamp holder, the inwall of screw lamp holder will be to fixture block 21 active force left, make fixture block 21 around the shaft 213 clockwise directions rotate, and compress spring 212.Because rotating shaft 213 is arranged on the eccentric position of connector, like this, after fixture block 21 turned to certain angle, the dop D of fixture block 21 can be trapped in the opening 22, and at this moment, the forward that no longer influences connector 2 screws.

When connector 2 oppositely screws out (clockwise direction), the inwall of screw lamp holder will make fixture block 21 contact with projection 214, so fixture block 21 can not rotate again to fixture block 21 active force to the right.At this moment, if be further rotated connector 2, the active force of the dop D of fixture block 21 and the inwall of screw lamp holder will further stop the rotation of connector 2.Obviously, connector 2 can not go out in reverse rotation.
