[0025] The adjustable safety sign fixing assembly 3 includes a connecting block 301 symmetrically mounted on the outer front wall of the enclosure plate 2, a slot is provided on the top of the connecting block 301, an L-shaped mounting plate 302 is provided in the slot, fixing screws 303 are passed through the L-shaped mounting plate 302 and the connecting block 301, a transverse connecting plate 304 with a strip groove on the side is connected to the bottom of the L-shaped mounting plate 302, a bidirectional screw rod 305 is rotatably connected in the strip groove on the side of the transverse connecting plate 304, the bidirectional screw rod 305 can rotate in situ in the strip groove, and a handle is also provided at one end of the bidirectional screw rod 305.

[0026] Both ends of the bidirectional screw rod 305 are threadedly connected with a sign positioning back frame 306, and avoidance holes 307 are arranged in a linear array on the sign positioning back frame 306. The safety slogan sign 4 is arranged on one side of the sign positioning back frame 306, and one end of the safety slogan sign 4 is connected to a positioning front panel 308. The outer side wall of the positioning front panel 308 is provided with a piercing sharp rod 309 in a linear array. One end of the piercing sharp rod 309 penetrates the safety slogan sign 4 and extends into the avoidance hole 307. Installation screws 310 are passed through the two ends of the positioning front panel 308 and the two ends of the sign positioning back frame 306. The positioning front panel 308 can squeeze and fix the safety slogan sign 4, and the piercing sharp rod 309 can pierce the piercing sharp rod 309, thereby ensuring that the safety slogan sign 4 will not fall off.

[0028] When the utility model is in use, the user can first connect the horizontal base 1 with the installation surface, so that the utility model can be fixed. After multiple utility models are installed, the construction site can be closed. When fixing the safety slogan sign 4, the user can adjust the distance between the two sign positioning back frames 306 according to the size of the safety slogan sign 4. When making specific adjustments, the user can drive the two sign positioning back frames 306 to move after the bidirectional screw rod 305 works, so that the distance between the two sign positioning back frames 306 is changed, so that the safety slogan sign 4 of different sizes can be used. For the purpose of coordination, after the adjustment is completed, the user can place the safety slogan sign 4 on the sign positioning back frame 306, and then the user can fit the positioning front panel 308 on the safety slogan sign 4. At the same time, the piercing sharp rod 309 needs to be passed through the safety slogan sign 4. After the positioning front panel 308 is connected, the user can use the installation screw 310 to connect the positioning front panel 308 and the sign positioning back frame 306 as one. The above method avoids leaving nail holes in the enclosure plate 2. When an emergency occurs at the construction site, escape can be carried out nearby through the emergency exit 5, which is highly practical.
