If groove to lamp holder outboard end, the outboard end of lamp holder sets a fixed block, and oscillating rod external part is inserted into the card of the fixed block
Rotated in groove and with fixed block and be connected by rotational pin.
As preferred technical scheme, a capping is provided with the top of the lamp holder, the bottom side of the capping is set
There is a rotating shaft, water tight lamp holder when at the top of 360 degree of rotation, capping rotation to lamp holder is realized in capping by rotating shaft.
As preferred technical scheme, the contact jaw of the pumping rod and lamp holder is set with a silica gel sheath, and pumping rod is passed through
The silica gel sheath.
As preferred technical scheme, first fixed cover and the second fixed cover are filled between wick for gap respectively
Match somebody with somebody, be provided through a fastening screw in the middle of it.
As preferred technical scheme, a spring, spring top and oscillating rod lower surface are installed on the groove bottom surface
Contact, the groove that fixed block water tight lamp holder side is opened up.
The beneficial effects of the utility model are：Alcolhol burner of the present utility model, pumping rod can be being dragged using after complete, you can
By in wick retraction and lamp holder, fire extinguishing is realized, without using external light cover, split type light cover is solved and easily loses and operate
The problem of trouble.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the accompanying drawing used required in description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
It is some embodiments of the present utility model, for those of ordinary skill in the art, is not paying the premise of creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is overall structure diagram of the present utility model.
Embodiment
All features disclosed in this specification, or disclosed all methods or during the step of, except mutually exclusive
Feature and/or step beyond, can combine in any way.
Any feature disclosed in this specification (including any accessory claim, summary and accompanying drawing), except non-specifically is chatted
State, can alternative features equivalent by other or with similar purpose replaced.I.e., unless specifically stated otherwise, each feature
It is an example in a series of equivalent or similar characteristics.
As shown in figure 1, including lamp body 1, wick 8 and lamp holder 2, the upper end of lamp body 1 sets a base 16, the bottom of lamp holder 2 with
Assembled between lamp body 1 by screw thread detachable, the one end of wick 8 is placed in lamp body 1, the other end passes through lamp holder 2 to the outside of lamp holder 2
End, the side of lamp holder 2 sets a pumping rod 15, and the one end of pumping rod 15 is provided with the first fixed cover 13, and the first fixed cover 13 is wrapped up
Outside wick 8, its other end stretches out in and one second fixed cover 12 is also enclosed with the outside of lamp holder 2, wick 8, and second fixes
One end of set 12 is connected by an oscillating rod 7, and the other end of oscillating rod 7 passes through the groove opened up on lamp holder 2 to lamp holder outboard end,
The outboard end of lamp holder 2 sets a fixed block 3, and the external part of oscillating rod 7 is inserted into the neck of the fixed block 3 and by rotational pin 4
Rotate and be connected with fixed block 3.
A capping 11 is provided with the present embodiment, at the top of lamp holder, the bottom side of the capping is provided with a rotating shaft 9,
Water tight lamp holder 2 when at the top of 360 degree of rotations, the rotation of capping 11 to lamp holders is realized in capping 11 by rotating shaft 9, when the retraction of wick 8 in
After in lamp holder 2, you can the water tight lamp holder 2 of rotary closure 11, air-isolation realizes fire extinguishing.
In the present embodiment, the contact jaw of pumping rod 15 and lamp holder 2 is set with a silica gel sheath 14, and pumping rod 15 passes through the silica gel
Set 14, by the water tight lamp holder 2 of silica gel sheath 14, prevents air from entering, can be by lamp as long as pulling out pumping rod 15 in operation
