Referring to fig. 2-3 and 8-10, the lower functional base 202 is provided with a plurality of ball storage groove bag members, the number of the ball storage groove bag members is equal to that of the linkage disc 208 and corresponds to one another, the ball storage groove bag members include a bag lying groove 301 arranged inside the lower functional base 202, an elastic bag 302 is arranged in the bag lying groove 301, a ball outlet pipe 303 is arranged at the top end of the elastic bag 302 in a penetrating manner, a plurality of smoke alarm balls 304 are filled in the elastic bag 302 and the ball outlet pipe 303, a ball outlet 305 matched with the smoke alarm balls 304 is arranged on the outer wall of one side of the ball outlet pipe 303, an elastic ball limiting sheet 306 is fixedly connected to the inner wall of the ball outlet 305, a ball pushing rod 209 is fixedly connected to the outer wall of the linkage disc 208, the ball pushing rod 209 penetrates through the outer wall of the ball pipe 303 and extends to abut against the smoke alarm balls 304, the elastic ball limiting sheet 306 is positioned on one side of the smoke alarm balls 304 away from the ball pushing rod 209, the elastic ball limiting sheet 306 abuts against the ball pushing rod 209, and the elastic ball limiting sheet 306 is made of elastic metal sheet material, the outer wall of the ball pushing rod 209 is sleeved with a return spring 210, through the arrangement of the ball pushing rod 209, the return spring 210 and the ball storage groove bag piece, when the level is inclined, the incline sensing iron ball 207 rolls towards the inclined direction, the incline sensing iron ball 207 can impact the corresponding linkage disc 208, the linkage disc 208 drives the ball pushing rod 209 to push the smoke alarm ball 304, so that the smoke alarm ball 304 breaks through the limitation of the elastic ball limiting sheet 306 on the smoke alarm ball and smoothly passes through the ball outlet 305, the alarm function is triggered, the elastic ball bag 302 is in an expansion state, the inner diameter of the ball outlet pipe 303 is gradually reduced from bottom to top, after the ball pushing rod 209 is reset, the elastic ball bag 302 can contract and rebound to a certain degree, the smoke alarm ball 304 below is extruded to abut against the ball pushing rod 209, the alarm function can be triggered repeatedly, and the practicability is greatly improved.

Referring to fig. 8 and 11, a ball receiving warning component embedded in the lower functional base 202 is disposed below the ball storage tank bag component, the ball receiving warning component includes a water storage ball 401, a ball guide tube 402 and an air guide tube 403 are disposed on an outer wall of the water storage ball 401 in a penetrating manner, the ball guide tube 402 is matched with the ball outlet hole 305, and one end of the ball guide tube 402, which is far away from the water storage ball 401, is communicated with the ball outlet hole 305, so that the smoke warning ball 304 can slide into the water storage ball 401 along the ball guide tube 402 after passing through the ball outlet hole 305, the water storage ball 401 is filled with water, and the smoke warning ball 304 is formed by iodine and zinc in a ratio of 1: 1-2, one end of the air duct 403 far away from the water storage ball 401 is abutted against the inner wall of the connecting sleeve 203, and initially, the air duct 403 is abutted against the connecting sleeve 203, can play a sealing role to prevent the water in the water storage ball 401 from flowing out, after the connecting sleeve 203 is rotated and lifted, will be separated from the gas-guide tube 403 to make the gas-guide tube 403 communicate with the outside, the iodine and zinc are not easy to combine directly at normal temperature, but after adding water as catalyst, can react violently and generate purple gas, so that after the smoke alarm ball 304 falls into the water storage ball 401, the gas guide pipe 403 can discharge the purple gas outwards, thereby warn the staff, make the staff in time adjust the surveyor's level, and can roughly judge the incline direction according to the position that has purple gaseous air duct 403 that flows out, and then can be favorable to the staff to the adjustment of surveyor's level, improved the practicality greatly.

The smoke alarm prompt flat base is arranged, so that when the level is inclined in the measuring process, the inclination sensing iron ball 207 can be separated from the magnetic force constraint of the magnet block 212, and rolls in the tilting direction, so that the tilt sensing iron ball 207 has the function of sensing the tilting of the level gauge, and the arrangement of the ball storage groove bag part and the ball receiving warning part is combined in parallel, so that the rolling of the tilt sensing iron ball 207 can impact the corresponding linkage disc 208, the smoke warning ball 304 is pushed to fall into the water storage ball 401, further based on the principle that iodine and zinc can generate purple gas under the catalysis of water, the purple gas flows out of the corresponding gas guide pipe 403, thereby warning workers and prompting the workers to adjust the level in time, further, errors can be effectively reduced, the inclination direction can be roughly judged according to the orientation of the air duct 403, further, the adjustment of a staff to the level can be facilitated, and the practicability is greatly improved.
