Furthermore, even fixedly connected with tooth piece on the inner wall of rotatory circle 213, the even fixedly connected with tooth in surface of gear 214, tooth piece figure is four times of tooth, and gear 214 all meshes with the inner wall of rotatory circle 213 mutually, and tooth piece figure through fixing on the inner wall of rotatory circle 213 is four times of the fixed tooth number of gear 214, can make rotatory circle 213 when rotating, and its inside can constantly mesh with gear 214, drives gear 214 and carries out the interlock.

A method for installing an external cleaning mechanism of a camera of a face recognition device is characterized by comprising the following steps: the method comprises the following specific operation steps:

the method comprises the following steps: when a user installs the device, the user directly places the device on a fixed desktop, the suction cup 217 is in contact with the desktop placement position, then the user can connect the screwing piece 212 by screwing, the connecting screwing piece 212 continuously drives the connecting plate 211 and the rotating ring 213 to rotate in the operation bin 210, while the rotating ring 213 rotates in the operation bin 210, the fixed tooth block on the inner wall of the rotating ring 213 continuously collides with the gear 214, after the gear 214 is resisted, the first threaded rod 215 rapidly rotates, the first threaded rod 215 is mutually matched with a thread structure arranged on the operation bin 210, the first threaded rod 215 can continuously move downwards in the operation bin 210 to rapidly form extrusion force on the pressing block 216,

step two: after the pressure block 216 is stressed, the suction disc 217 can continuously abut against a placed desktop, after the suction disc 217 is squeezed, residual gas inside the suction disc 217 can be rapidly squeezed and conveyed to the inside of the communicating pipe 218, the pressure inside the communicating pipe 218 gradually begins to increase and forms a certain pressure difference with the external air pressure, after the sealing plate 222 is subjected to the pressure difference, the sealing plate 222 rapidly moves outwards inside the air outlet 219, so that the inside of the air outlet hole 221 is opened outwards, meanwhile, the sealing plate 222 continuously pulls the spring 223 during movement, so that the spring 223 deforms, gas circulating inside the communicating pipe 218 can be conveyed outwards until the gas inside the communicating pipe 218 is exhausted completely, the pressure inside the communicating pipe 218 is rapidly constant, and through the resilience force generated after the spring 223 deforms, the sealing plate 222 can be rapidly attached to the surface of the air outlet hole 221 to seal the air outlet hole, the suction cup 217 can be firmly attached to the surface of the table top because the air inside the suction cup 217 is exhausted.

The working principle is as follows: when a user uses the device and needs to install the device, the user can directly place the device on a fixed desktop, so that the suction cup 217 is in contact with the placement position of the desktop, then the user can simply connect the screwing piece 212 through screwing, so that the connecting screwing piece 212 continuously drives the connecting plate 211 and the rotating ring 213 to rotate in the operation bin 210, the rotating ring 213 continuously collides with the gear 214 while rotating in the operation bin 210, the gear 214 quickly drives the first threaded rod 215 to rotate after being abutted, the first threaded rod 215 is matched with a threaded structure arranged on the operation bin 210, the first threaded rod 215 can continuously move downwards in the operation bin 210, the pressing block 216 is quickly formed into an extrusion force, the suction cup 217 can be acted after the pressing block 216 is stressed, so that the suction cup 217 can continuously abut against the desktop, after the suction cup 217 is squeezed, residual gas inside the suction cup 217 can be rapidly squeezed and conveyed into the communicating pipe 218, so that the pressure inside the communicating pipe 218 gradually begins to increase, a certain pressure difference is formed between the pressure inside the communicating pipe 218 and the outside air pressure, after the sealing plate 222 is subjected to the pressure difference, the sealing plate 222 rapidly moves outwards inside the air outlet 219, so that the inside of the air outlet 221 is opened outwards, meanwhile, when the sealing plate 222 moves, the spring 223 is continuously pulled to deform the spring 223, and as the inside of the air outlet 221 is opened outwards, gas circulating inside the communicating pipe 218 can be continuously conveyed outwards until the gas inside the communicating pipe 218 is completely exhausted, the pressure inside the communicating pipe 218 is rapidly constant, the sealing plate 222 is rapidly driven to automatically reset through resilience force generated after the spring 223 deforms, and the sealing plate 222 can be rapidly attached to the surface of the air outlet 221, the air in the sucker 217 is exhausted, the pressure in the sucker 217 is in a positive pressure state, the sucker 217 can be firmly adsorbed on the surface of a table top, otherwise, a user can connect the screwing piece 212 through reverse screwing, so that the first threaded rod 215 continuously pulls the pressing block 216 and contracts towards the inside of the operation cabin 210, the pressing block 216 simultaneously pulls the sucker 217, the outside air can quickly enter the inside of the sucker 217, the internal pressure of the sucker 217 is quickly constant, and the user can quickly finish the disassembly of the camera main body 100;

if the user during the actual use of the device encounters a part of crowd with a relatively high height, the user can screw the second threaded rod 310, the second threaded rod 310 is matched with the threaded structure formed on the threaded sleeve 312 and is matched with the sliding rod 315 to limit the position of the camera body 100, so that the threaded sleeve 312 can quickly drive the camera body 100 to move left and up after the second threaded rod 310 is screwed, and when the camera body 100 moves up, the second fixing member 317 can drive the sliding sleeve 316 to continuously slide on the ground surface of the sliding rod 315, the user can quickly adjust the placement height of the camera body 100, if the user needs to adjust the lens angle of the device during the actual use, the user can screw the screwing block 325, the screwing block 325 is matched with the threaded structure formed on the second fixing member 317, so that the screwing block 325 can continuously drive the moving member 323 to move left on the surface of the second fixing member 317, until the moving member 323 drives the plug-in components 324 to leave the inside of slot 322, the user then can be quick rotate camera main body 100, accomplish the regulation to camera main body 100 camera lens locating position fast, after the user accomplishes the regulation to camera main body 100 camera lens locating position, the user then can be quick reverse screw the piece 325 of twisting, make the piece 325 of twisting drive plug-in components 324 fast and remove the inside that gets into slot 322, fix second mounting 317 fast, fix the angle of adjustment of camera main body 100, and the convenience is brought to the user.
