The use method and the advantages of the invention are as follows: the special support frame for the lens of the face recognition device comprises the following steps:

the method comprises the following steps: as shown in fig. 3 and 4, after the lens is installed in the housing 24, the seat plate 4 is placed on the base 1, and in the process, the slider 42 is inserted into the inside of the buckle slot 30, and then the screw 34 is rotated, as shown in fig. 1 and 2, under the action of the screw transmission, the screw 34 applies a pushing force to the push rod 36, so that the push rod 36 pushes the push rod 2 to move upwards through the connecting rod 37, the push rod 2 moves upwards while stretching the spring four 38, so that a restoring force behind the spring four 38 and simultaneously moving the frustum 3 upwards, the frustum 3 moves upwards to apply a pressing force to the two clamping plates 32 through the side walls thereof, so that the two clamping plates 32 move away from each other and compress the corresponding spring three 31, so that the spring three 31 obtains a restoring force, and at the same time, the clamping plates 32 push the corresponding slider 42 to move towards the side walls of the buckle slot 30 and are inserted on the side walls of the buckle slot 30, the five springs 43 are compressed in the moving process of the sliding block 42, so that the five springs 43 obtain restoring force, the bottom plate 4 is fixed, the operation is very simple, only the screw rods 34 need to be rotated, and time and labor are saved;

when the seat plate 4 needs to be taken down, the screw rod 34 is rotated reversely, so that the screw rod 34 is far away from the push rod 36, the push rod 36 does not apply force to the connecting rod 37 and the ejector rod 2, the ejector rod 2 drives the frustum 3 to move downwards and reset under the action of the restoring force of the spring four 38, the two clamping plates 32 are not squeezed by the downward movement of the frustum 3, the two clamping plates 32 are close to each other under the action of the restoring force of the spring three 31, the clamping plates 32 are far away from the corresponding sliding blocks 42, and the sliding blocks 42 are far away from the side walls of the catching grooves 30 and reset under the action of the restoring force of the spring five 43, so that the seat plate 4 is disassembled, the operation is simple and convenient, and the lens is convenient to take down for overhauling and;

step two: as described above, after the seat plate 4 is installed, as shown in fig. 1, during the process of raising the frustum 3, an upward force is applied to the lifting rod 29, so that the lifting rod 29 drives the lifting plate 22 to move upward, and the second spring 23 is stretched, so that the second spring 23 obtains a restoring force, and after the lifting plate 22 rises, the second bevel gear 12 and the motor 20 are synchronously driven by the sliding base 21 to move upward, and the second bevel gear 12 is meshed with the first bevel gear 11;

when external wind is large, the impeller 40 is driven to rotate rapidly, so that the shaft sleeve 9 is driven to rotate by the polygon bar 7, the rotation of the shaft sleeve 9 synchronously drives the sliding sleeve 44 to rotate, so that the sliding sleeve 44 drives the centrifugal rod 46 to rotate, so that the centrifugal rod 46 obtains centrifugal force, the centrifugal rod 46 stretches the spring six 45 under the action of the centrifugal force, so that the spring six 45 obtains restoring force, the centrifugal rod 46 exerts force on the conical surface of the ring plate 8 through the wedge surface, the balls 47 play a role in reducing friction, so that wind energy is better captured, the centrifugal rod 46 drives the shaft sleeve 9 to move to the right through the sliding sleeve 44 in the axial direction of the polygon bar 7, so that the shaft sleeve 9 drives the cantilever 14 to move to the right through the sleeve ring 10 and the sliding rod 15, the right movement of the sliding rod 15 stretches the spring one 5, so that the spring one 5 obtains restoring force, so that the cantilever 14 drives the motor 20 and the bevel gear two, and make the bevel gear two 12 and the bevel gear three 13 engage and connect, cantilever 14 and key switch 6 are not contacted at this moment, the electrical machinery 20 does not work by electricity, bevel gear five 19 and bevel gear four 17 do not engage, thus guarantee under the sufficient condition of wind-force, utilize wind-force as the power source, drive axle sleeve 9 and bevel gear one 11 to rotate through the rotation of the multi-edge pole 7, make bevel gear one 11 drive bevel gear three 13 to rotate through bevel gear two 12, thus make bevel gear three 13 drive transparent plate 26 to rotate through spindle 18, will turn the area stained with dirt in the transparent hole 25 to the scraper 28 in the course of the transparent plate 26 rotates, make the scraper 28 clean the dirt, and the area after cleaning rotates to the transparent hole 25, thus keep the clear picture when the lens is shot and recorded, and realize the real-time cleaning to the lens, save labour, easy to maintain, save energy consumption, the dirt scraped by the scraper 28 is discharged from the through hole at the bottom of the round box 27;

when the wind power is small enough to drive the impeller 40 to rotate, at this time, the polygon bar 7 and the shaft sleeve 9 do not rotate, the centrifugal bar 46 does not have a centrifugal force, at this time, the centrifugal bar 46 slides into the sliding sleeve 44 and resets under the action of the restoring force of the spring six 45, at the same time, the sliding bar 15 moves to the left under the action of the restoring force of the spring one 5 and synchronously drives the cantilever 14 and the lantern ring 10 to move to the left, the left movement of the lantern ring 10 synchronously drives the shaft sleeve 9 to move to the left, the left movement of the cantilever 14 synchronously drives the sliding seat 21 to move to the left, so that the bevel gear two 12 is far away from the bevel gear three 13, the bevel gear five 19 is close to the bevel gear four 17, when the bevel gear five 19 is meshed with the bevel gear four 17, the cantilever 14 is in abutting contact with the key switch 6 and communicates with the key switch 6, so that the motor 20 is powered on, the, therefore, under the condition of low wind power, the transparent plate 26 is driven to rotate by using electric energy, so that the cleanness of the transparent plate 26 is ensured, and the cleanness of the lens is further kept;

step three: as described in the first step, after the base plate 4 is detached from the base 1, the frustum 3 has no upward force on the lifting rod 29, so that the lifting plate 22 moves downward and resets under the restoring force of the second spring 23, as shown in fig. 3, the downward movement of the lifting plate 22 drives the second bevel gear 12 and the motor 20 to move downward through the sliding base 21, so that the second bevel gear 12 is separated from the first bevel gear 11 and the cantilever 14 is dislocated from the push-button switch 6, so that the motor 20 is kept out of operation during maintenance of the lens, and energy consumption is avoided.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and the preferred embodiments of the present invention are described in the above embodiments and the description, and are not intended to limit the present invention.
