[0025] In this embodiment, when the device connects the flower stem bottom cone 1 with the flower stem rod body 2, the multiple connecting columns 3 of the flower stem bottom cone 1 are first aligned with the multiple plug-in holes 4 of the flower stem rod body 2, and then the two can be plugged together. After the two connecting columns 3 are fully inserted into the two plug-in holes 4, the two inner limit holes 5 and the outer limit hole 6 will be completely aligned. At this time, the bayonet pin 7 can be inserted horizontally from the outside of the outer limit hole 6 until its other end extends to the other end of the outer limit hole 6. At this time, the connection between the flower stem bottom cone 1 and the flower stem rod body 2 is completed.

[0026] The flower stem bottom cone 1 and the flower stem rod body 2 of the device are connected by a snap-in pin 7. The top of the flower stem bottom cone 1 is vertically fixedly connected with two connecting columns 3, and the bottom end of the flower stem rod body 2 is provided with a corresponding plug-in hole 4. When connecting, the two structures can be docked first, and then the snap-in pin 7 is inserted into the two structures to fix them after the docking is completed, thereby completing the connection between the flower stem bottom cone 1 and the flower stem rod body 2. With this connection method, no matter how the staff twists it, there will be no relative displacement between the flower stem bottom cone 1 and the flower stem rod body 2, which can prevent the connection between the two from loosening, thereby ensuring the overall stability of the device.

[0027] When the device is actually used, multiple sections of the flower stem body 2 may be installed, and the same connection structure is used when the multiple sections of the flower stem body 2 are connected.

[0028] Furthermore, one end of the outer limit hole 6 is expanded outward to form an outward expansion groove 8, and a first magnetic ring 9 is fixedly connected to the interior of the outward expansion groove 8.

[0034] In this embodiment, the auxiliary support structure can support the device. In actual use, people can rotate the screw rod 21. When the screw rod 21 rotates, it can move along the length direction of the adjusting tube 20 under the action of the thread inside the adjusting tube 20, thereby changing the overall length of the adjusting tube 20 and the screw rod 21. After the length is changed, it can drive the support tube 16 to rotate, change its inclination angle, and position it, so that multiple inclined support tubes 16 can play a supporting role. At the same time, when the threaded rods 17 at the bottom ends of the multiple support tubes 16 rotate, the overall length of the support tubes 16 and the threaded rods 17 can also be changed, so that the multiple auxiliary support structures of the device can be adjusted in length according to the actual situation of the ground, ensuring that the device can always be in a vertical state.

[0035] Furthermore, a level ruler 23 is fixedly connected to the outer surface of the stem body 2 .
