A camera mounting method using a camera mounting device, comprising the steps of:

the method comprises the following steps: when the camera 1 is installed, water and cement with the mass part ratio of 1:3 are placed in the stirring cavity 13, and the camera 1 and the high-pressure air tank 4 are fixedly connected to the supporting frame.

Step two: and (3) screwing the fastening bolts fixedly connecting the rotating box 6 and the stirring box 7 with the support frame by using a spanner.

Step three: the support frame 19 and the camera 1 are horizontally placed on the surface of the wall body so that the suction cup 15 is in full contact with the wall body.

Step four: the outer rod is pulled by 4cm in the direction of the camera 1, the inner rod relatively slides in the outer rod to enable the inner cavity to form suction force to the one-way valve 16, so that residual gas in the sucker 15 can be completely sucked out of the inner cavity through the one-way valve 16, the sucker 15 forms vacuum, and the high support frame 19 can be stable on a wall body. The position of the poke rod on the scale mark is adjusted according to the required drilling depth, the poke rod can drive the pressure switch 17 to the corresponding scale mark position, when the inner rod slides to the position of the pressure switch 17, the depth of the drill 10 in the wall body is the distance, and therefore the drilling depth of the drill 10 can be determined.

Open high-pressure gas case 4 to let in high-pressure gas in rotating chamber 12, high-pressure gas can blow helical blade 8, thereby makes helical blade 8 rotate, and rotatory helical blade 8 can drive drill bit 10 and rotate. The rotating drill bit 10 will drive the mixing blade 9 to rotate, and the rotation of the mixing blade 9 will mix the cement and water in the mixing chamber 13 and make the cement and water fully mixed. The high pressure gas entering the rotating chamber 12 will enter the venturi 18 through the second solenoid valve 20, the high pressure gas enters from the diverging section and exits from the converging section, and a negative pressure will be created at the throat.

When the drill 10 rotates, a hole is drilled in the wall, the support frame 19 is manually extruded towards the wall, and the drill 10 drills into the wall under the action of manual pressure. The drill 10 generates a large amount of dust when it drills into a wall, and the negative pressure generated by the venturi tube 18 sucks the dust through the guide tube and the dust sucked into the venturi tube 18 is adsorbed by the adsorption layer, thereby facilitating the dust disposal. When the drill bit 10 drills into the wall, the reaction force of the wall pushes the inner rod to slide in the outer rod, and when the inner rod slides to the position of the pressure switch 17, the drill bit 10 reaches the required drilling depth. The inner rod can extrude the pressure switch 17, and the friction force between the inner rod and the pressure switch 17 enables the inner rod to be clamped by the pressure switch 17, so that the inner rod cannot slide relatively in the outer rod, the inner rod cannot slide and contract in the outer rod, the support frame 19 cannot slide towards the wall, and the drill bit 10 cannot be pushed towards the wall. The pressure switch 17 is opened by the pressing of the inner lever, the first solenoid valve 14 is opened, and the second solenoid valve 20 is closed.

The high-pressure gas in the high-pressure gas tank 4 can enter the stirring cavity 13, and the high-pressure gas blocked by cement cannot be directly blown onto the stirring blade 9, so that the stirring blade 9 cannot rotate and cannot drive the drill bit 10 to continue to rotate. The high-pressure gas enters the stirring chamber 13 more and more, and the pressure inside the stirring chamber 13 increases. The increased pressure may squeeze the cement, causing the cement to squeeze the diaphragm to break. Cement enters the hole drilled by the drill bit 10 through the discharge pipe 11 and attaches the drill bit 10 to the wall body, so that the drill bit 10 is fixed in the wall body, and the high-pressure air tank 4 is closed after the cement in the stirring cavity 13 is completely extruded.

Step five: and after the fourth step is finished, the high-pressure air box 4 is detached from the support frame 19, and the high-pressure air box 4 is opened to blow the cement for 8 min. After the camera 1 is installed, if vibration occurs, the effect of the inner rod and the outer rod of the fixing rod 5 can buffer the camera 1.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, it is possible to make various changes and modifications without departing from the concept of the present invention, and these should be construed as the scope of protection of the present invention, which will not affect the effect of the implementation of the present invention and the utility of the patent. The techniques, shapes, and structural parts, which are omitted from the description of the present invention, are all known techniques.
