[0027] Insert the main body 11 of the electrical fire monitor into the inner cavity of the installation frame 10. At this time, multiple sets of clamping plates 17 are exactly inserted into the top position of the inner cavity of the clamping holes 13. Then start the forward and reverse motor 5 to drive the lead screw body 2 to rotate, so as to drive the lead screw nut 3 to move upward synchronously in the inner cavity of the first strip hole 4. Under the action of the lead screw nut 3, the fixing plate 15 can be driven to move upward, so that multiple sets of clamping plates 17 can be clamped to the bottom position of the inner cavity of the clamping holes 13, and then the position of the main body 11 of the electrical fire monitor can be fixed. When disassembly is required, just start the forward and reverse motor 5 to drive the lead screw body 2 to rotate in the reverse direction, so as to drive the clamping plates 17 to reset. Then the hand of the staff passes through the two second strip holes 12, and then the main body 11 of the electrical fire monitor can be pulled out to separate the clamping plates 17 from the clamping holes 13.

[0028] Please refer to the attached drawings of the specification Figure 1 , multiple sets of limit holes 14 are provided inside the fixing plate 15, and limit rods 16 passing through the limit holes 14 are installed on the inner wall of the installation frame 10.

At this time, multiple clamping plates 17 are exactly inserted into the top position of the inner cavity of the clamping holes 13. Then start the forward and reverse motor 5 to drive the lead screw body 2 to rotate, which can drive the lead screw nut 3 to move upward synchronously in the inner cavity of the first strip hole 4. Under the action of the lead screw nut 3, the fixing plate 15 can be driven to move upward, so that multiple clamping plates 17 can be clamped to the bottom position of the inner cavity of the clamping holes 13, and then the position of the electrical fire monitor body 11 can be fixed.

[0033] When disassembly is required, just start the forward and reverse motor 5 to drive the lead screw body 2 to rotate in the reverse direction, which can drive the clamping plates 17 to reset. Then, the worker's hand passes through the two second strip holes 12, and the electrical fire monitor body 11 can be pulled out to separate the clamping plates 17 from the clamping holes 13.

[0034] After the electrical fire monitor body 11 is clamped into the inner cavity of the mounting frame 10, under the elastic force of the spring 8, the metal elastic sheet 9 is automatically pushed to deform and the end is tilted up, so that it can cooperate with the top wall of the inner cavity of the mounting frame 10 to squeeze and fix the position of the electrical fire monitor body 11, so that the electrical fire monitor body 11 will not move accidentally during use.
