the accuracy of the pixel is determined according to the number of pixels between two adjacent graduation marks, and the determination of the pixel received by the photographing unit 506 means that, in order to pursue higher accuracy, the size of the pixel of the photograph of the photographing unit 506 can be changed, so that the practicality is high.
The working principle of the invention is as follows: when the steel tape is put into the pushing device 2, the motor of the first gear motor 204 is started to rotate the transmission long gear rod 203, the transmission long gear rod 203 and the transmission bevel gear rod 202 are in transmission connection at the same side, so that the transmission long gear rod 203 drives the transmission bevel gear rod 202 to rotate in the same direction, meanwhile, when the first gear motor 204 rotates due to the circular ring arranged around the moving rod 2012 and the pushing groove 103, the pushing toothed plate 201 always drives with the gear groove 2011, so that the pushing toothed plate 201 moves according to the circular ring path arranged in the pushing groove 103 through the gear groove 2011 and the transmission bevel gear rod 202, the top end of the pushing toothed plate 201 moves the steel tape as a whole to the pulling groove 102, and when the steel tape is moved, the steel tape hook is clamped into the tooth to increase the pushing force, and when the steel tape is pushed to the edge of the pushing toothed plate 201, the steel tape hook is positioned on the smooth plane, so that the friction force of the tape is increased;
when the steel tape is pushed continuously, the steel tape is attached to the baffle plate 501 of the calibration main body 5, during attachment, the push of the push force causes the hook of the steel tape to fall into the pulling groove 102, so that the hook of the steel tape is positioned at one side of the pulling block 301 close to the second gear motor 305, the steel tape is subjected to upward force due to the special shape of the power trigger block 5032, the power trigger block 5032 is compressed, the power trigger block 5032 contacts the second motor power switch-on block 5021, the two sides of the power trigger block 5032 are switched on, the delay switch is electrified, the motor of the second gear motor 305 is rotated, the rotating rod 304 is rotated, the wire spool 303 is rotated, the pulling rope 302 is wound by the rotation of the wire spool 303, the pulling block 301 is moved, thereby the steel tape is dragged, the pulling block 301 is used for clamping the hook of the steel tape, meanwhile, the blocking plate 501 is used for blocking, so that the pulling block 301 can only be used for pulling the hook to draw out the tape, in the continuous dragging of the pulling block 301, the pulling block 301 is continuously dragged, when the clamping component 4 is out, the clamping block 401 is retracted when the pulling block 301 is touched, the clamping spring 402 is compressed, when the stopping groove 3011 passes, the clamping spring 402 releases the elastic force, so that the clamping block 401 is clamped into the stopping groove 3011, so that the clamping block 401 presses the photographing switch 108 to trigger the photographing unit component 506, thereby performing photographing operation, and because the pulling rope 302 is provided with a certain ductility, and meanwhile, the winding of the pulling rope 302 on the wire spool 303 is not tight enough, thereby the clamping block 301 is clamped, the continuous rotation of the motor rotation of the second gear motor 305 can make the pulling rope 302 wound on the spool 303 compact, at this time, after compacting, the pulling block 301 stops at the clamping assembly 4 for a period of time due to the action of the ductility of the pulling rope 302, so that the pulling block 301 can take a clear photo, and the shooting operation can be performed for a plurality of times, according to the shooting distance set by the spacing between the clamping assembly 4 and the accurate integer scale 104, generally 3 times, the maximum measuring range is controlled by the processor at the position of 100mm, the position of 1000mm and the predetermined maximum measuring range of the steel tape respectively, when the time delay switch reaches the set time, the second gear motor 305 stops supplying power, and at this time, the steel tape hook can be retracted due to the fact that the pulling force cannot be received, and when retracting, the steel tape hook can be retracted due to the blocking of the pulling block 301, the speed of the pulling block 301 is slowed down, and the pulling of the pulling rope 302 can not generate the phenomenon of jumping, and at the same time, the speed is further weakened due to the blocking of the clamping assembly 4 until the pulling block 301 is rebounded until the pulling block 301 is contacted with the pulling block 102, and the pulling tape hook is continuously retracted to the side of the inertia switch 102, and the pulling tape hook is retracted after the time the inertia switch is contacted with the pulling block 102, the filtering groove is continuously retracted
When the screening switch 306 is turned on, the processor is electrified, so that the difference of the lengths of the integral parts of the steel tape in the picture shot by the shooting unit component 506 is quickly identified, the integral value pixel point data input into the shooting position in the processor is compared, the pixel point comparison under the same pixel is carried out, the number of the offset pixel points is known through the processor, then an actual error value is obtained according to gamma=alpha (+/-beta), meanwhile, the actual error value is displayed at the display at the top end of the calibration main body 5, and then whether the comparison exceeds a specified error permission range is carried out, after the error value exceeds the error allowance range, the processor causes the third gear motor 5054 to reversely rotate, so that the rack plate 5053 drives the classification translation plate 5051 to move to one side, so that the classification plate 5052 drives the steel tape to topple over, and when the error range is specified, the processor causes the third gear motor 5054 to positively rotate, so that the rack plate 5052 drives the classification plate 5051 to move to the other side, so that the error value needing to be calibrated is known;
at this time, the power trigger assembly 503 is separated from the extrusion state, so that the power trigger spring 5031 releases the elastic force, so that the power trigger block 5032 is withdrawn, so that the return switch-on block 5022 is electrified, and the processor drives the third gear motor 5054 to perform homing operation.
It is to be noted that, in particular, "stop at such a time that the pulling block 301 is stopped at the seizing assembly 4" is mainly achieved by the pulling rope 302 being a power rope, so that there is a certain ductility, and by the pulling rope 302 being wound around the spool 303, it is not tight enough to wind itself, so that the pulling block 301 is seized at the seizing assembly 4 for a certain residence time; of course, the material of the pull rope 302 is selected according to the actual situation, and nylon ropes are generally selected, so that the pull block 301 is stopped at the position of the clamping assembly 4 for a longer time when the pull block is used due to the high ductility and the good rebound effect, so that the photographing unit assembly 506 is ensured to be stationary when photographing, and the photographing unit assembly 506 does not have the influence of speed pulling. So that the photographing is clear.
Finally: the foregoing description of the preferred embodiments of the invention is not intended to limit the invention to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and principles of the invention are intended to be included within the scope of the invention.
