[0022] See also Figures 1 to 5 The utility model provides a technical solution: a GPS device with a removal alarm function, comprising: a plurality of mounting seats 2 and a plurality of limiting columns 5, the limiting columns 5 are respectively arranged inside the mounting seats 2, and the GPS body 1 is fixedly installed on the outer periphery of the limiting columns 5, the mounting seats 2 are all hollow and a limiting cavity 7 is provided in the middle of the mounting seats 2.

[0023] A fixed column 12 is fixedly installed in the middle of the limit column 5, and a plurality of evenly distributed movable grooves 20 are provided on the outer periphery of the fixed column 12. A movable rod 11 is slidably installed in the movable groove 20. A fixed plate 9 is fixedly installed on the top of the movable rod 11 of the same group. Two connecting rods 21 are symmetrically installed on the upper part of the movable rod 11. The limiting block 8 is rotatably installed on the side of the connecting rod 21 on the same side away from the movable movable rod 11. A plurality of evenly distributed compression springs 10 are fixedly installed in the middle of the top of the fixed plate 9. The top of the compression spring 10 is fixedly installed on the bottom end of the fixed column 12 on the same side. A notch 19 is provided on the upper outer periphery of the limit column 5 and the notch 19 is adapted to the limit block 8. By pulling the pull ring 18, the movable plate will move in the movable groove 20, and the limit block 8 will follow As the movable rod 11 moves synchronously, the compression spring 10 is compressed until the limit block 8 retracts into the cavity of the limit column 5. At this time, the limit cavity 7 releases the limit on the limit column 5, and the staff can quickly disassemble the GPS body 1. When the mounting seat 2 is needed, just reinsert the limit column 5 into the mounting seat 2 and release the pull ring 18. At this time, the compression spring 10 will drive the fixing plate 9 to reset, and the movable rod 11 will drive the limit block 8 to extend from the slot 19, and cooperate with the limit cavity 7 to quickly fix the GPS body 1. At the same time, the limit cavity 7 and the limit block 8 are both provided with wedge surfaces. When the two wedge surfaces abut each other, the limit column 5 can be installed and fixed, which is beneficial to improve the staff's efficiency in disassembly and assembly of the GPS body 1 and facilitates the maintenance of the GPS body 1.

[0024] The upper part of the outer periphery of the mounting seat 2 is fixedly installed with a plurality of evenly distributed fixing ears 3. By setting the fixing ears 3 and cooperating with the fixing screws, the mounting seat 2 can be fixed to ensure the stability of the GPS body 1 during use. A pressure plate 17 is fixedly installed on the middle part of the top of the limit column 5, and a telescopic rod 6 is fixedly installed on the middle part of the top of the mounting seat 2. A reset spring 13 is sleeved on the outer periphery of the telescopic rod 6, and an abutment plate 14 is fixedly installed on the bottom end of the telescopic rod 6.
