The working principle is as follows: when the anti-shake folding type movable support for photography and video shooting is used, the device is moved to a shooting place, then the top plate 15 is pressed downwards through the pressing handle 14, when the top plate 15 moves downwards, the lifting rod 17 is driven to move downwards, meanwhile, the first spring 16 is compressed, then the top plate 15 is limited through the downward rotating bolt 12, when the lifting rod 17 moves downwards, the lifting plate 25 is driven to move downwards, at the moment, due to the meshing effect between the rack 23 and the arc-shaped covers 22, the two arc-shaped covers 22 rotate upwards along the pin shafts on the lifting plate 25, then the lifting plate 25 extends downwards to be below the containing box 18 and is unfolded, meanwhile, parts mounted on the lifting plate 25 also extend downwards, and due to the weight block 27, the gravity centers of the weight block 27, the arc-shaped rods 26 and the camera 10 are located right below the ball rod 31 and the mounting seat 24, namely, and are located right below a fulcrum, the line of action of force at this moment passes through the fulcrum, and the arm of force is zero to can make balancing weight 27 and camera 10 remain vertical balanced state throughout, that is to say that camera 10 can be in a horizontally state and shoot, thereby can make the picture of shooting more stable, improve the shooting effect.
Meanwhile, when the top plate 15 moves downwards, the third connecting rod 9 drives the first connecting rod 7 and the second connecting rod 8 to rotate, then the first connecting rod 7 can drive the first supporting seat 6 to move towards the direction away from the base box 1, and simultaneously the first sliding rod 4 and the piston plate 30 are driven to move together, which is equivalent to increase the supporting area of the base box 1, thereby improving the overall stability, when the two piston plates 30 move away from each other, the internal pressure of the base box 1 between the two piston plates 30 can be reduced, thereby sucking air inwards through the sucking disc 29, at this moment, if shooting is carried out on a smoother surface, at this moment, the sucking disc 29 can also be used for adsorbing and fixing on the smoother surface, and further the base box 1 is fixed again to improve the stability.
Like this, through the height of adjusting roof 15 from top to bottom, then carry on spacingly to it through bolt 12, can reach the effect of stretching out and accomodating camera 10 to can also increase the support area of base case 1 when stretching out the shooting, thereby improve stability, and can also withdraw first support seat 6 when accomodating, reduce area occupied, and improve space utilization, be convenient for deposit.
If when outdoor shooting is carried out and inclined shooting is carried out, after the camera 10 and the first supporting seat 6 are unfolded, the two bolts 11 are pulled out, the limit on the two racks 23 is cancelled, at the moment, the moving block 3 on the inclined side slides along the outer wall of the first sliding rod 4, meanwhile, one of the racks 23 is driven to slide downwards through the connection action of the pull rope 2, meanwhile, one of the elastic telescopic rods 32 is compressed, when the rack 23 slides downwards, the adjacent arc cover 22 is driven to rotate and rotate downwards through the meshing action of the arc cover 22, because outdoor shooting possibly has the influence of backlight and inclined shooting is carried out, the rotated arc cover 22 can achieve the effect of shading the camera 10, and the rotating degree of the arc cover 22 can be determined according to the inclined degree, so that the shooting of the camera 10 can be prevented from being influenced by the backlight, thereby improving the shooting effect.
Then after shooting, withdraw first support seat 6, withdraw camera 10 simultaneously, can drive rack 23 under the elastic force effect of elasticity telescopic link 32 this moment and reset, then insert bolt 11 again and lock rack 23 can, camera 10 withdraws the back in addition, two arc covers 22 can roll out, and close together, can wrap up camera 10, can play certain guard action to camera 10.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
