irregular arc shapes, the outer magnetic plate 8 can be enabled to receive uneven force when swinging occurs, and then the outer slide bar 9 can slide along the axial direction of the outer magnetic plate 8 conveniently, so that two sides of the outer slide bar 9 can swing one on another conveniently.

When the base 1 is used, the base can be fixed on the surface of a building through screws, at this time, the upper support arm 505 and the lower support arm 506 can be fixed at a certain angle through the screw pin on the end surface when the upper support arm 505 and the lower support arm 506 can be respectively rotated to a proper position through the fixing joint 504 near one side of the mounting cylinder 5, at this time, the antenna box 507 can be finely adjusted again through the fixing joint 504 far from one side of the mounting cylinder 5, so that the antenna box is inclined at a certain angle, thereby preventing birds from inhabiting the top end of the antenna box 507, furthermore, when snow rain water is attached to the outer surface of the outer cylinder 12, heat generated by the operation of electrical components inside the antenna box 507 can be guided to the inside of the outer cylinder 12 through the heat conducting hose 503, thereby facilitating the efficiency of melting snow and evaporating rain water, when birds fall on the outer surface of the outer cylinder 12 and press down the outer cylinder 12 with a certain gravity, at this time, the outer cylinder 12 can make the outer gimbal 10 press down the outer magnetic plate 8 through the connecting rod 11, and then the outer magnetic plate 8 and the inner magnetic plate 7 can make the second gimbal 605 respectively drive the pneumatic rods 604 on both sides to instantly extend and contract through homopolar repulsion, and at the same time when the pneumatic rods 604 on both sides instantly extend and contract, the first gimbal 603 can make the outer swivel 602 drive the outer sliding sleeve 601 to slide on the outer surface of the inner ball cake 6, and then can make both ends of the outer cylinder 12 swing up and down, and further can make the center of gravity unstable at the instant when the birds fall on the outer surface of the outer cylinder 12, and further prevent the birds from inhabiting on the outer surface of the outer cylinder 12, and after the birds fly away, the outer magnetic plate 8 and the inner magnetic plate 7 can restore to the original position again through repulsive magnetic force, so as to prevent the subsequent birds from inhabiting again, and when the outer sliding rod 9 swings up and down, the inner rolling balls 906 on both sides can roll in the same direction inside of the outer cylinder through the heightening sloping plate 905, when the inner rolling ball 906 on one side rolls to the highest point of the middle part of the heightening inclined plate 905 and has a tendency of returning from the original path, the inner rolling ball 906 on the other side is in contact with the inner slide block 904 and can compress the inner spring 903 through the inner rolling ball 906, when the inner spring 903 is compressed to the limit, the inner rolling ball 906 on the other side can rebound again through the inner slide block 904, and then the inner rolling balls 906 on the two sides can move in a mirror image mode again, so that the swinging frequency of the two ends of the outer slide rod 9 can be accelerated, and further, flying birds can be prevented from perching on the outer surface of the outer barrel 12, in addition, when accumulated snow is accumulated on the outer surface of the outer barrel 12, the accumulated snow can be fallen off, when the outer slide rod 9 and the outer barrel 12 swing up and down instantly, the balance rod 1001 can be driven by the outer universal joint 10, and when the swinging frequency of the outer slide rod 9 and the outer barrel 12 is increased, the inner top rod 1002 can collide with the inner wall of the outer barrel 12, and the outer springs 1003 on the two sides can drive the collision ball 1004 to move up and down due to expand respectively due to inertia, and the collision ball 1004 can be knocked and made to make a sound respectively to the outer surface of the outer slide bar 9 and the inner wall of the outer tub 12, so that the bird can be repelled by the sound when the bird inhabits on the outer surface of the outer tub 12.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
