[0022] A working column 4 is fixedly connected to the protective dosimeter body 1, and the working column 4 can make the protective dosimeter body 1 be placed normally on the ground. A working groove 5 is provided at one end of the working column 4 away from the protective dosimeter body 1, and a threaded sleeve 6 is rotatably connected in the working groove 5, and a working screw 7 is threadedly connected in the threaded sleeve 6. A working suction cup is fixedly connected to the end of the working screw 7 away from the threaded sleeve 6, and the working suction cup squeezes the ground to form a negative pressure, thereby producing an adsorption and fixing effect. A limiting component is provided in the working groove 5, and the limiting component includes a limiting plate 8 fixedly connected to the side wall of the working groove 5, and the working screw 7 slides through the limiting plate 8. A limiting block is provided on the limiting plate 8, and a limiting slide groove is provided on the working screw 7. The limiting block and the limiting slide groove are cooperatively arranged, thereby limiting the working screw 7 so that it can only slide up and down along the direction of the threaded sleeve 6;

[0023] A transmission assembly is also provided in the working groove 5, and the transmission assembly includes a bevel gear 19 fixedly connected to the threaded sleeve 6. A working shaft 10 is rotatably connected in the working groove 5. One end of the working shaft 10 passes through the working column 4. A handle is provided on the working shaft 10. The handle is disc-shaped. The handle and the working shaft 10 are matched to make it more convenient for the staff to rotate the working shaft 10. One end of the working column 4 close to the threaded sleeve 6 is fixedly connected to a bevel gear 2 11. The bevel gear 19 and the bevel gear 2 11 are meshed, so that when the working shaft 10 is rotated, The threaded sleeve 6 is driven to rotate by gear transmission, and a fixing component is also provided on the working bracket 2, which includes an auxiliary screw 12 rotatably connected to the working bracket 2.
