The implementation scenario is specifically as follows: when measuring distance in the vertical direction, the second motor 17 is started to drive the screw rod 18 to rotate, the guide plate 21 on the nut seat 20 can only move up and down along the second limiting frame 16, so that the rotation of the nut seat 20 is limited, the screw rod 18 rotates to enable the nut seat 20 on the screw rod 18 to move upwards, the movable end of the second measuring tape 19 is further pulled to move upwards through the connecting plate 22, so that the distance measurement in the vertical direction is carried out by using the second measuring tape 19, meanwhile, the nut seat 20 moves upwards to drive the guide plate 21 to move upwards, the rectangular block 24 is further driven to move upwards through the sliding rod 23, the threaded rod 25, the second spiral drill rod 26, the pull rope 27 and the second clockwork spring 28 are further driven to move upwards, when the second measuring tape 19 measures the required distance, at the moment, the second spiral drill rod 26 also moves to the required distance, then, the second motor 17 is closed, the pull ring 44 with the proper height on the pull rope 27 is pulled or stepped downwards by feet, make the stay cord 27 of winding on threaded rod 25 loosen and then make threaded rod 25 rotate, because threaded rod 25 passes through threaded connection with rectangular block 24, so threaded rod 25 rotates simultaneous movement, and then drive second auger stem 26 and bore into the demand position and beat the point, threaded rod 25 rotates simultaneously and drives second clockwork spring 28 and rotate and make second clockwork spring 28 produce elasticity, threaded rod 25 reverses under elasticity and drives second auger stem 26 and return the normal position after loosening pull ring 44, then start second motor 17 once more, repeat above-mentioned step and carry out the measurement of next position and beat the point, and then realize the ascending multi-distance location of vertical side and beat the point function.
Although the invention has been described in detail above with reference to a general description and specific examples, it will be apparent to one skilled in the art that modifications or improvements may be made thereto based on the invention. Accordingly, such modifications and improvements are intended to be within the scope of the invention as claimed.
