The bottom of the bottom member 204 is provided with a bottom groove 205 of a conical structure, and a pull groove 206 is opened through the inside of the bottom member 204 to control the lateral displacement of the control structure 207, so that the control structure 207 is displaced inside the pull groove 206, and at the same time, the air inside the bottom groove 205 is squeezed out, so that the bottom member 204 is adsorbed and fixed on the ground, thereby improving the fixing effect of the positioning device 1 and preventing the positioning device 1 from being displaced or tipped over after encountering a collision during use.

[0025] In the present disclosure, Figure 3 and Figure 4As shown, two arc-shaped stoppers 102 are fixed at the front end of the connecting head 101, which cooperate with the connecting head 101 to fix the positioning device 1, and an inner part 103 is fixed at the middle position inside the connecting head 101, and the inner end of the inner part 103 is an arc-shaped structure, which is positioned and inserted into the inside of the slot 106, so that the positioning device 1 is positioned and connected with the connecting rod assembly 105; the connecting rod assembly 105 is inserted into the inside of the connecting head 101 and the stopper 102, and a slot 106 is provided at the rear of the connecting rod assembly 105, and the inner part 103 is inserted into the inside of the slot 106 with an arc-shaped structure inside; a card slot 107 is provided at the front end of the connecting rod assembly 105, and the fixing assembly 104 is inserted into the inside of the card slot 107 and fixed, so that the positioning device 1 is fixedly connected with the connecting rod assembly 105, and the bottom end of the connecting rod assembly 105 is connected to the support rod assembly 108 through a rotating shaft, and the bottom end of the support rod assembly 108 is a spherical structure, and is rotatably connected to the support head structure 2, so that when supporting the positioning device 1, the use angle can be freely adjusted.
