in the drawing process, if the lines at a certain position are not convenient to draw, the drawing board 6 can be transversely rotated, and the drawing method is as follows:
the internal pressure pull rod 29 drives the positioning clamping rod 27 to move, so that the gear teeth on the positioning clamping rod 27 are disconnected from being meshed with the positioning gear 26, and the second compression spring 31 is compressed;
then the drawing board 6 is rotated through the bearing connection of the drawing board 6 and the connecting groove 28, after the drawing board 6 is rotated to a proper angle, the pull rod 29 is released, the pull rod 29 is reset through the reset of the second compression spring 31, so that the pull rod 29 is meshed with the positioning gear 26 again, and the rotated drawing board 6 is fixed;
when a plotter draws, the longitudinal ruler 10 and the transverse ruler 11 can respectively move in the displacement groove 9 on the side of the drawing board 6 and move in the through groove 13 on the transverse ruler 11 through the longitudinal ruler 10, so that the aim of drawing a straight line by using the longitudinal ruler 10 and the transverse ruler 11 is fulfilled;
when the plotter draws, if the drawing board 6 is not facing the model to be drawn, the plotter can draw the model by turning the drawing board 6 so that the drawing board 6 faces the model to be drawn, specifically as follows:
the driving transverse rod 22 is stepped to drive the driving longitudinal rod 20 to move downwards;
when the longitudinal rod 20 is driven to move downwards, the movable ring 18 is driven to move downwards, so that a first compression spring 19 between the movable ring 18 and the fixed ring 17 is extruded;
when the driving longitudinal rod 20 moves downwards, the driving longitudinal rod gradually extends into the positioning clamp tube 24, and drives the internal thread ring 15 to rotate through the ratchet mechanism 25;
when the internal thread ring 15 rotates, the internal thread ring can move on the single-rotation reciprocating screw rod 14;
when the internal thread ring 15 moves, the first sliding block 2 is driven to synchronously move in the limiting groove 23;
when the first sliding block 2 moves, the supporting rod 3 is driven to move synchronously;
when the supporting rod 3 moves, the second sliding block 4 is driven to move synchronously, the second sliding block 4 is driven to rotate and slide in the sliding groove 12, and then the supporting panel 5 is driven to twist, so that the drawing board 6 above the supporting panel 5 is twisted (when the supporting panel 5 is twisted, the positions of two ends of the driving transverse rod 22 are also changed, and the driving transverse rod 22 can be stably moved up and down to drive the driving longitudinal rod 20 to stably move up and down under the condition that the length of the driving transverse rod 22 is not changed by setting the connecting mode of the driving transverse rod 22 and the driving longitudinal rod 20 to be the same as the connecting mode of the supporting rod 3 and the supporting panel 5);
after the driving transverse rod 22 is loosened, the driving longitudinal rod 20 is reset under the action of the first compression spring 19, and due to the arrangement of the ratchet mechanism 25, the driving longitudinal rod 20 cannot drive the internal thread ring 15 to rotate when being reset;
the driving of the crossbar 22 by repeated pressing causes the drawing plate 6 to continue to twist until the drawing plate 6 is twisted into a position facing the model, something not described in detail in this description being known to a person skilled in the art.
It is to be understood that the terms "central," "longitudinal," "lateral," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in the orientations and positional relationships indicated in the drawings for the purpose of convenience and simplicity of description, and do not indicate or imply that the referenced devices or components must be in a particular orientation, constructed and operated in a particular orientation, and are not to be considered limiting of the scope of the present invention.
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.
