[0028] The first magnetic block 14 is slidably connected to the first installation groove 9 and the second installation groove 15 respectively.

[0029] Exemplarily, the first magnetic block 14 and the second magnetic block 16 fix the first connecting rod 1 and the second connecting rod 4 by adsorption.

[0030] The interior of the first groove 2 abuts against the second connecting rod 4 , and the interior of the second groove 5 abuts against the first connecting rod 1 .

[0031] Furthermore, the first groove 2 and the second groove 5 facilitate limiting the first connecting rod 1 and the second connecting rod 4. When the first connecting rod 1 and the second connecting rod 4 are respectively stuck in the first groove 2 and the second groove 5, the angle between them is exactly the installation angle of the device.

[0032] One end of the first connecting rod 1 is internally rotatably connected with a connecting shaft 3 , and a side wall of the connecting shaft 3 is rotatably connected to the second connecting rod 4 .

[0033] Preferably, the connecting shaft 3 facilitates the rotation of the first connecting rod 1 and the second connecting rod 4 .

[0034] A fixing assembly for fixing the device when it is stored is commonly provided on the plurality of first connecting rods 1 and the second connecting rods 4 .

[0036] In this embodiment, the magnetic plate 7 and the iron block 8 are adsorbed to fix the first connecting rod 1 and the second connecting rod 4 when they are stored.

[0037] The fixing rod 6 is connected to the magnetic plate 7 via a damping bearing, and the magnetic plate 7 is rotatably connected to the first connecting rod 1 and the second connecting rod 4 respectively.

[0038] In some other embodiments, the damping bearing is used to prevent the magnetic plate 7 from rotating randomly and affecting the swinging ball when the device is in use.

[0039] Working principle: When the utility model is used, the first connecting rod 1 and the second connecting rod 4 are rotated through the connecting shaft 3 to adjust the angle. The first groove 2 and the second groove 5 are convenient for limiting the first connecting rod 1 and the second connecting rod 4. When the first connecting rod 1 and the second connecting rod 4 are respectively stuck in the first groove 2 and the second groove 5, the angle between the two is exactly the installation angle of the device. The first magnetic block 14 can be stored in the first connecting rod 1, so that the device can be installed by connecting in sequence, or by directly clamping the first connecting rod 1 and the second connecting rod 4 after adjusting the angle, which is convenient for the installation of the device;
