[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] 1. Through the designed limit mechanism, the extrusion cylinder will squeeze the spring along the outer wall of the limit circular plate, and the spring will generate a rebound force. When the start button is squeezed by Panasonic, the spring will reset. During the reset process, the limit block will be pushed out from the inside of the transverse groove. After that, the torsion spring will be used to rotate the limit block to its original position to avoid a downward squeezing force during the working process, which will cause it to be accidentally touched, thereby enhancing practicality.
[0014] 2. Through the designed rubber pad, when the alarm is subjected to a lateral impact force, the rubber pad will absorb the impact force to prevent the force from being directly absorbed by the alarm, thereby protecting the alarm. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] See also Figure 1-5 The utility model provides a technical solution: a building fire alarm device, including an alarm 1, a fire button 2, a start button 3, and a warning light 4. The alarm 1 is provided with fire buttons 2 all around, the alarm 1 is movably installed with a start button 3 inside, and a warning light 4 is arranged on the side of the start button 3. An active cavity 6 is provided inside the alarm 1, and a movable sleeve 7 is fixedly installed inside the active cavity 6. A transverse groove 8 is provided on the top of the inner cavity of the movable sleeve 7, and a baffle 9 is fixedly installed on the side of the transverse groove 8. The bottom of the movable sleeve 7 is fitted and connected with a limiting mechanism; the limiting mechanism includes a limiting circular plate 12, a telescopic rod 11, a spring 13, and an extrusion cylinder 10. The top of the limiting circular plate 12 is fixedly connected to the bottom of the telescopic rod 11, the top of the telescopic rod 11 is movably sleeved with the spring 13, the top of the telescopic rod 11 is movably sleeved with the inside of the extrusion cylinder 10, and the top of the extrusion cylinder 10 and the bottom of the start button 3 are movably installed.
[0023] When the start button 3 needs to be used during operation, the start button 3 is rotated clockwise, causing the limit block 14 fixedly installed at the bottom of the start button 3 to rotate into the top of the transverse groove 8. When the rotation continues at that time, the baffle 9 will generate a blocking force, which can limit the start button 3 at the top of the transverse groove 8. At this moment, it is pressed downward, and the limit block 14 will extend into the interior of the transverse groove 8, and the bottom of the limit circular plate 12 will start the alarm device, thereby facilitating alerting. During the downward pressing process, the extrusion cylinder 10 will squeeze the spring 13 along the outer wall of the limit circular plate 12, and the spring 13 will generate a rebound force. When the force of the start button 3 is squeezed by Panasonic, the spring 13 will be reset, and the limit block 14 will be pushed out from the inside of the transverse groove 8 during the resetting process. Then, the limit block 14 will be rotated to its original position by the reset force of the torsion spring 15, avoiding a downward squeezing force during the operation.
[0024] Specifically, a rubber pad 5 is fixedly installed at the bottom of the alarm 1 , and a mounting cavity is opened at the bottom of the alarm 1 , and the interior of the mounting cavity and the outer wall of the rubber pad 5 are fixedly connected.
[0025] In this embodiment, when the alarm 1 is subjected to a lateral impact force, the rubber pad 5 will absorb the impact force to prevent the force from being directly absorbed by the alarm 1, thereby protecting the alarm 1.
