The distance and posture correcting device 3 can correct errors generated by gradients and angles between the device and a horizontal plane, when a worker holds the device to measure the distance, if the road surface is uneven, the measured distance can be longer than the actual distance, at the moment, the numerical value can be corrected through the effect of the gradient feedback device 302, the left bracket 201, the first rod 30201 and the second rod 30202 form a parallelogram with corners different from 90 degrees when the four-bar mechanism encounters an uneven road surface, the generated angles can drive the first groove 30204 to move upwards or downwards, the first groove 30204 drives the front rack 30404 to move upwards or downwards, the movement of the rack can drive the upper gear 3047 to move upwards or downwards in combination with the lower gear 30402, so that the gear rod 30307 is driven to move, when the gear rod 30307 moves upwards, the lower motion feedback block 30304 is driven to move downwards, the upper motion feedback block 30308 moves upwards, the upper motion feedback block 30308 drives the first sliding rail 30303 to move upwards, at the moment, the friction pulley is driven by the spline to move upwards, the friction pulley 30101 is driven by the friction device 30101 to move upwards, the friction pulley 30101 is greatly, and the friction ratio of the friction device is greatly changed, and the friction device 30101 is greatly measured. Because the frame 2 is connected with the first wheel frame 106 and the second wheel frame 107 by only one shaft of the lower central shaft 202, when a worker operates, the worker is difficult to keep the horizontal state of the integral device for a long time, so that the posture feedback device is introduced, the large heavy hammer of the posture feedback device always keeps vertical and horizontal planes, if the integral device has an included angle with the horizontal planes, the integral device and the posture feedback device also have a certain included angle, the rotation of the heavy hammer supporting frame 30503 can drive the second groove 30504 to move upwards or downwards, the movement of the second groove 30504 can drive the rear rack 30505 to move, and the influence of the rear rack 30505 on the transmission ratio of the large friction wheel 30109 is the same as the influence principle of the front rack 30508 on the large friction wheel 30109, thereby correcting errors generated due to the posture of the heavy hammer supporting frame.
