s6, finally, drawing a line using an external ruler for a part of the line not suitable for the caliper 4.
The working principle is as follows: when the positioning mechanism is used, a drawing is fixed on the upper end surface of a workbench 1, the position of a first positioning rod 5-1 is changed through the sliding and extending of a first telescopic arm 7-1, the first positioning rod 5-1 slides downwards after reaching a preset position, so that the bottom of the first positioning rod 5-1 is contacted with a paper surface, (refer to figure 4), at the moment, a conical anti-slip plug 8-2 moves downwards relative to a conical anti-slip groove 8-1-1 along with the first positioning rod 5-1 (when the conical anti-slip plug 8-2 is contacted with the conical anti-slip groove 8-1-1, the friction force has large friction force, the friction force prevents the positioning mechanism from rotating relative to a sliding sleeve 8-1), so that the first positioning rod 5-1 can rotate relative to the sliding sleeve 8-1, further, the positioning mechanism can rotate around the sliding sleeve 8-1 by taking the first positioning rod 5-1 as an axis, then, the second positioning rod 5-3 is adjusted to reach a preset position by rotating the positioning mechanism and adjusting the sliding mode of the second positioning rod 5-3 relative to the auxiliary ruler 5-2, after the second positioning rod 5-3 reaches the preset position, the auxiliary ruler 5-2 is moved downwards, the auxiliary ruler 5-2 drives the second positioning rod 5-3 to move downwards, so that the lower end of the second positioning rod 5-3 contacts with the paper surface, meanwhile, the auxiliary ruler 5-2 downwards extrudes the sliding sleeve 8-1, so that the sliding sleeve 8-1 moves downwards relative to the fixed sleeve 8-3, further, the spring 8-4 is compressed, the first buckle 8-5 moves downwards and is clamped with the second buckle 8-6, so that the auxiliary ruler 5-2 and the sliding sleeve 8-1 keep the downwards moving position and cannot reset (if the auxiliary ruler 5-2 needs to reset and the position of the second positioning rod 5-3 is adjusted again, then the upper end of the first buckle 8-5 is pressed to enable the lower end of the first buckle 8-5 to rotate upwards, further the first buckle 8-5 and the second buckle 8-6 are separated, under the action of the elastic force of the spring 8-4, the auxiliary ruler 5-2 is reset, the second positioning rod 5-3 moves upwards and is suspended above the paper surface again, then the position of the caliper 4 on the connecting line of the first positioning rod 5-1 and the second positioning rod 5-3 is moved, in the process, the rectangular connecting rod 5-8 slides along the guide rail 5-7, the second gear 6-7 moves relative to the rack 5-2-1, further, the second gear 6-7 rotates under the action of the rack 5-2-1, the second gear 6-7 drives the first gear 6-6 to rotate, the first gear 6-6 drives the third gear 6-8 to rotate, the third gear 6-8 drives the rotating ring 6-9 through the inner gear 6-5 (and the rotating linear speed and direction of the rotating ring 6-9 are the same as the moving speed and direction of the caliper 4), so that the rotating ring 6-9 can extrude a paper surface in the moving process of the caliper 4, the error of the position of the caliper 4 caused by the fact that the paper surface is not attached to the workbench 1 is prevented, the rotating ring 6-9 reduces abrasion on the paper surface in a rolling mode, and the quality of a final drawing is improved;
after the caliper 4 reaches a preset position, the guide rail 5-7 is pressed downwards, the guide rail 5-7 drives the caliper 4 to move downwards through the rectangular connecting rod 5-8 to be attached to a paper surface, meanwhile, the first L-shaped telescopic rod 5-4 extends downwards, further, the limiting rod 5-4-1 at the lower end of the first L-shaped telescopic rod 5-4 moves downwards along with the downward extension of the first L-shaped telescopic rod 5-4, the end position of the limiting rod 5-4-1 is overlapped with the lower end part of the first buckle 8-5, the lower end part of the first buckle 8-5 is prevented from rotating upwards, and the first buckle 8-5 and the second buckle 8-6 are kept in a clamping state; meanwhile, the rectangular connecting rod 5-8 moves downwards along the rectangular groove 6-4 to enable the elastic rope 9-3 to be pulled downwards, further, the elastic rope 9-3 pulls the lower end of the limiting plate 9-2 rightwards through the steering of the steering shaft 9-1, the upper end of the limiting plate 9-2 extrudes the second gear 6-7 leftwards, the second gear 6-7 cannot rotate through the friction force of the limiting plate 9-2 and the second gear 6-7, further, the rotating disc is prevented from moving relative to the auxiliary ruler 5-2, and the position of the caliper 4 is fixed; make equipment when slide caliper rule 4 laminating drawing uses, lock first flexible arm 7-1 and positioning disk, make slide caliper rule 4's position by the lock, when avoiding drawing, because the user leaves midway or reasons such as wrong touch lead to slide caliper rule 4's position change, and then make the line position change, lead to the risk of the final quality decline of drawing.
