[0025] In this embodiment, a screw rod 19 is fixedly connected to the top of the second bevel gear 18, and a screw nut 20 is sleeved on the screw rod 19. The screw nut 20 is adapted to the screw rod 19, and the screw nut 20 is passed through the sleeve plate 3, and the screw nut 20 is fixedly connected to the sleeve plate 3.

When the sleeve plate 3 moves, it will move along the limiting rods 21, and the position of the sleeve plate 3 will not be offset when it moves, thereby ensuring stability during movement.

[0027] In this embodiment, the top and bottom of the mounting frame 1 are fixedly connected with mounting plates 22 .

[0028] In this embodiment, four mounting holes in a square arrangement are defined on the mounting plate 22 .

[0029] Working principle: When using this device, screws can be used to pass through the mounting holes on the mounting plate 22 to fix the device to the wall. The device can be installed horizontally, and the position of the composite smoke and heat detector body 14 can be adjusted to detect different areas. The device can be installed vertically, and the position of the composite smoke and heat detector body 14 can be adjusted to detect areas at different heights. The composite smoke and heat detector body 14 and the motor 16 are powered by an external power supply, and the motor 16 is connected to the controller through a wire. The temperature in the building is monitored and smoke is detected through the composite smoke and heat detector body 14. When smoke or temperature detection is required in areas at different positions or heights, the motor 16 can be started by the controller, and the power The output end of the motor 16 will drive the first bevel gear 17 to rotate, the first bevel gear 17 will drive the second bevel gear 18 to rotate, the second bevel gear 18 will drive the screw rod 19 to rotate, the screw rod 19 will drive the screw nut 20 to move, the screw nut 20 will drive the sleeve plate 3 to move along the limit rod 21, the sleeve plate 3 will not deviate when moving, the movement of the sleeve plate 3 will drive the first square plate 8 to move, the first square plate 8 will drive the card block 9 to move, the card block 9 will drive the fixed plate 10 to move, the fixed plate 10 will drive the composite smoke and heat detector body 14 to move, the position of the composite smoke and heat detector body 14 can be adjusted, and each area can be detected by programming the PLC programmable controller to make the output of the motor 16 The output end continuously rotates forward and reverse to continuously adjust the position of the composite smoke and heat detector body 14, and in the process of adjustment, the roller 7 will not move to the bevel of the trapezoidal guide plate 2. When installing the composite smoke and heat detector body 14, the fixing plate 10 on the composite smoke and heat detector body 14 can be sleeved on the block 9, and then the motor 16 is started to rotate the screw rod 19, and the screw rod 19 drives the screw nut 20 to rise, which can also make the sleeve plate 3 rise, and the sleeve plate 3 will drive the plug plate 4 to rise, and the plug plate 4 will drive the fixing seat 5 to rise, and the fixing seat 5 will drive the roller 7 to rise, and the roller 7 will contact the bevel of the trapezoidal guide plate 2, and the roller 7 will rise along the bevel of the trapezoidal guide plate 2, so the two rollers 7 will also rise in the process of rising. When the two fixing seats 5 are close to each other, the roller 7 will drive the fixing seat 5 to move close to the sleeve plate 3, and the fixing seat 5 will squeeze the spring 6 to shrink the spring 6. When the two fixing seats 5 are close to each other, the second square plate 11 will be driven to move close to the fixing plate 10. The second square plate 11 will drive the insertion rod 12 to move close to the fixing plate 10 until it is inserted into the slot 13, so that the fixing plate 10 can be limited to ensure that the composite smoke and heat detector body 14 will not fall during the movement. When the roller 7 moves to the vertical edge of the trapezoidal guide plate 2, the insertion rod 12 will be completely inserted into the slot 13. When the composite smoke and heat detector body 14 needs to be disassembled for its inspection and maintenance, the output end of the motor 16 is reversed to make the sleeve plate 3 continue to move in the direction of the motor 16.When the roller 7 moves to the bevel position of the trapezoidal guide plate 2 again and continues to move, the spring 6 will gradually expand, which will enable the two fixing seats 5 to move away from each other, and the two insertion rods 12 to move away from each other and out of the slots 13, thus releasing the limit on the fixing plate 10 and allowing the composite smoke and heat detector body 14 to be removed for inspection and maintenance.
