     As shown in  FIG. 1 , the invention provides a flickering electronic candle, including a candle body, wherein the candle body includes a first cylinder  1 , a second cylinder  2  connected with the first cylinder  1  and a third cylinder  3  connected with the second cylinder  2 . A flickering candle wick  4  is movably arranged in the first cylinder  1  through a support structure  5 , a flame front  7  is arranged at the top of the flickering candle wick  4 , and a magnet  6  is arranged at the bottom of the flickering candle wick  4 . The flame front  7  is preferably in a hollow flame shape, and an LED bulb  10  is arranged in the flame front  7 . In addition, a driving chip  9  is arranged in the second cylinder  2 , a power unit  11  is arranged in the third cylinder  3 , and the power unit  11  is respectively connected with the driving chip  9  and the LED bulb  10 . 
     The flickering candle provided by the present invention adopts the hollow flame front, the LED bulb is placed in the flame front, and the flame front and the internal bulb swing together, so that the flickering effect of the candle is more vivid; meanwhile, the candle is provided with different interconnected cylinders, the heights of the cylinders can be changed, and then the height of the candle can be changed, so that the candle can be matched with various external shells and is variable in style and high in ornamental value. 
     Preferably, the first cylinder  1  is clamped with the second cylinder  2 , and the diameter of the second cylinder  2  is not smaller than that of the first cylinder  1 ; the third cylinder  3  is sleeved with the second cylinder  2 , and the diameter of the third cylinder  3  is not smaller than that of the second cylinder  2 . 
     The flickering candle wick  4  is arranged inside the first cylinder  1 , the driving chip  9  is arranged inside the second cylinder  2 , an electromagnetic coil  8  on the driving chip  9  generates an electromagnetic field after being electrified, and the force generated by mutual repulsion between the electromagnetic field and the magnetic field of the magnet  6  at the bottom of the flickering candle wick  4  enables the flickering candle wick to deviate and swing; after the swinging device deviates from the balance position under the magnetic force, the swinging device may be subjected to self gravity; when the gravity is greater than the magnetic force, the swinging device may swing back; and in this way, the swinging device ceaselessly swings under the interaction of the magnetic force and gravity. Meanwhile, the flame front also swings, to produce the visual effect similar to a candle flame flickering, so that the flickering electronic candle is very vivid. 
     Preferably, the second cylinder  2  sequentially includes a first ferrule  21  and a plurality of second ferrules  22  from top to bottom, wherein a raised platform  12  is formed on the first ferrule  21 , two sides of the platform  12  are connected with vertical baffles  13 , and the driving chip is arranged in the platform  12 . A plurality of grooves  15  are formed in the lateral surface of the first cylinder  1 , a clamping hook  14  is arranged at the top of each baffle  13 , and the clamping hooks  14  are connected with the grooves  15  by cooperation. 
     The second cylinder  2  in the present invention is formed by sleeving the plurality of ferrules, so that the height of the candle can be selected according to actual demands. 
     Preferably, the driving chip  9  is specifically arranged below the flickering candle wick  4 , the electromagnetic coil  8  is arranged on the driving chip  9 , and the electromagnetic coil  8  is positioned below the magnet  6 . 
     The second cylinder is connected with the first cylinder, wherein the magnetic field generated by electrifying the electromagnetic coil on the driving chip interacts with the magnetic field of the magnet in the flickering candle wick arranged in the first cylinder to generate a force; and in order that the flickering candle wick swings more stably and attractively, the magnet and the electromagnetic coil are arranged oppositely. 
     Preferably, the flame front is further wrapped by a case  17 , such as a frosted silicon rubber case or a rubber case or a plastic case in the same shape. In order that the light of the LED bulb in the flame front is softer and more vivid, the flame front may be covered by the frosted silicon rubber case. 
     Preferably, the support structure  5  includes a support  51  and a support frame  52  movably hung on the support  51 , the support frame  52  includes a large support shaft  53  and a small support shaft  54  which are crossed with each other, a hollow frame  55  is arranged in the middle of the large support shaft  53 , the hollow frame  55  is used for supporting the small support shaft  54 , two ends of the small support shaft  54  are movably supported by the hollow frame  55 , two ends of the large support shaft  53  are movably hung on the support, and the flickering candle wick  4  is crossly connected with the small support shaft  54 .

The first cylinder is further provided with a hole through which an electric wire penetrates to connect the LED bulb with a power supply. 
     Preferably, the outer part of the candle body is connected with a shell  16 , and the shell  16  is cylindrical and lower than the candle body. 
     In the present invention, the shell  16  with different patterns is further preferably packaged outside the candle body, wherein the shell  16  is lower than the candle body to expose the flame front, so that flickering of the flame front can be clearly viewed during enjoying.
