[0034] In the present invention, when the threaded column 15 is axially rotated, the threaded column 15 controls the spline column 14 to move up and down through threaded transmission, thereby adjusting the height of the workbench 6.

[0035] Specifically, the rotating structure includes a rotating column 10, a second rotating hole is opened on the outer side of the spline cylinder 13, and the rotating column 10 is rotatably installed in the second rotating hole, a second bevel gear 16 coaxially arranged with the threaded column 15 is fixed at one end, a first bevel gear 12 coaxially arranged with the first bevel gear 12 and meshing with the second bevel gear 16 is fixed at one end of the rotating column 10, and a thumbwheel 11 coaxially arranged with the first bevel gear 12 is fixed at the other end of the rotating column 10;

[0036] In the present invention, the user moves the thumbwheel 11 with his foot, so that the thumbwheel 11 drives the rotating column 10 to rotate, and the first bevel gear 12 on the rotating column 10 rotates accordingly, and the first bevel gear 12 rotates the threaded column 15 through the second bevel gear 16 meshing with it.

[0037] Specifically, the outer side of the thumbwheel 11 is covered with a rubber sleeve 24 for increasing friction.

[0038] Specifically, the adjustment mechanism 4 includes a transmission rod 20, first rectangular grooves are formed on both sides of the top of the square frame plate 23, a second rectangular groove is formed at one end of the top of the square frame plate 23, third rotating holes are formed at both ends of the first rectangular groove, and threaded rods 17 are installed in the two third rotating holes for common rotation, a knob is fixed to one end of the threaded rod 17, and a third bevel gear 19 coaxially arranged therewith is fixed to the other end of the threaded rod 17, fourth rotating holes are formed at both ends of the second rectangular groove, and both ends of the transmission rod 20 are respectively installed in the two fourth rotating holes for rotation, two fourth bevel gears 21 coaxially arranged therewith and meshing with the two third bevel gears 19 are fixed to the outer side of the transmission rod 20, one end of the drawing board 3 is intersectingly installed on the square frame plate 23, a moving block 18 is provided on the outer side of the threaded rod 17 through a threaded sleeve, and a connecting rod 5 is installed for common rotation between the moving block 18 and the drawing board 3;

[0043] In the present invention, the spring positioning pin 8 is used to fix the square frame plate 23 and the workbench 6 .

[0044] Working principle: There are two working modes:

[0045] The first type is when drawing at a certain angle: since the third bevel gear 19, the transmission rod 20 and the fourth bevel gear 21 form a transmission pair, the transmission pair enables the two threaded rods 17 to rotate synchronously and in the same direction; when adjusting, by twisting one of the threaded rods 17, the two threaded rods 17 rotate synchronously and in the same direction through the transmission pair, and the threaded rod 17 drives the moving block 18 to move through the image of the threaded transmission, and the moving block 18 adjusts the angle of the drawing board 3 through the connecting rod 5;

[0046] The second type is when you need to draw on a plane, but you still need to draw at the previous angle later: pull the spring locating pin 8 out of the locating hole, and move the frame plate 23 out of the guide rail 9, that is, the frame plate 23 is separated from the workbench 6. At this time, the draftsman can draw on the workbench 6, and can also place other drawings on the drawing board 3 for analogy.

[0047] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
