Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-5A drawing workbench includes a support seat 1 and a work surface assembly 3. The bottom of the support seat 1 is supported by a bracket 2. A movable block 4 is arranged inside the support seat 1. The left and right sides of the movable block 4 are respectively penetrated by a screw rod 6 and a light rod 7. The screw rod 6 is threadedly connected to the movable block 4. The front end of the screw rod 6 is connected to a knob 8, and the knob 8 is arranged on the front side of the support seat 1. The front and rear ends of the light rod 7 are fixedly connected to the support seat 1. The bottom end surface of the work surface assembly 3 is rotatably connected to one end of the movable rod 5 through a rotating shaft, and the other end of the movable rod 5 is rotatably connected to the movable block 4 through the rotating shaft. The worktable assembly 3 includes a support plate 31, a fixed rotating shaft 32, a rotating table 33, a rotating shaft limiting device 34, a rotating shaft 35 and a universal ball 36. The front end bottom of the support plate 31 is rotatably connected to the support seat 1 through the fixed rotating shaft 32. The top surface of the support plate 31 is provided with a rotating table 33. The middle part of the bottom end of the support plate 31 is provided with a rotating shaft limiting device 34. The bottom end of the rotating shaft 35 is connected to the rotating shaft limiting device 34, and the top end of the rotating shaft 35 is connected to the rotating table 33. The universal ball 36 is installed at the edge of the bottom end surface of the rotating table 33.

[0025] The movable rod 5 is tilted and tilted upward from back to front, so that when the movable block 4 moves forward and backward, the support plate 31 is driven by the movable rod 5 to rotate along the fixed rotating shaft 32 to adjust the inclination angle of the work table assembly 3. The support plate 31 and the rotating table 33 are arranged in parallel, and the bottom end of the universal ball 36 is in contact with the support plate 31, and the universal ball 36 is arranged in a circular array with the rotating shaft 35 as the center. When the rotating table 33 rotates, the universal ball 36 at the bottom of the rotating table 33 rolls along the top surface of the support plate 31, and the universal ball 36 increases the support effect at the edge of the rotating table 33.

[0026] See also Figure 6, the rotating shaft limiting device 34 includes a shell 341, a gear 342, a limiting card plate 343, a connecting rod 344, a movable rotating shaft 345, a straight rod 346, a limiting frame 347, a movable plate 348, a spring 349 and a pull rod 3410. A gear 342 is arranged inside the shell 341, and two limiting card plates 343 are arranged. The right ends of the two limiting card plates 343 are respectively meshed with the upper and lower sides of the gear 342, and the left ends of the two limiting card plates 343 are rotatably connected to the shell 341 through a rotating shaft. Two connecting rods 344 are arranged, and the two connecting rods 344 are connected in a V shape, and the connection is rotated with each other through a movable rotating shaft 345. The outer ends of the two connecting rods 344 are rotatably connected to the two limiting card plates 343 through the rotating shaft, the right end of the straight rod 346 is fixedly connected to the movable rotating shaft 345, and the left end of the straight rod 346 horizontally penetrates the limiting card plate 346. The frame 347 and the movable plate 348 are fixedly connected with the pull rod 3410, and the movable plate 348 is arranged inside the limit frame 347. The left side of the movable plate 348 is elastically connected with the inner left wall of the limit frame 347 through the spring 349, and the spring 349 is sleeved on the outer side of the straight rod 346. The shell 341 is fixed to the middle of the bottom end of the support plate 31, and the center of the circle of the gear 342 is connected to the rotating shaft 35. The spacing between the two limit clamps 343 gradually decreases from right to left, and the rotation of the gear 342 is limited by the engagement of the two limit clamps 343 with the gear 342. The spacing between the two connecting rods 344 gradually decreases from left to right, so that when the straight rod 346 pulls the movable rotating shaft 345 to move to the left, the movable rotating shaft 345 moves to the left through the two connecting rods 344 to push the two limit clamps 343 to expand, and the engagement of the two limit clamps 343 with the gear 342 is disconnected.

[0027] In summary, when in use, the workbench is first placed on a desired plane position through the bracket 2, and the design drawing is fixed on the rotating table 33, and then drawing work can be carried out;

[0028] When the inclination angle of the work surface assembly 3 is adjusted, the screw rod 6 is driven to rotate by rotating the knob 8, and the screw rod 6 rotates to drive the movable block 4 to move forward and backward through the threaded fit between the screw rod 6 and the movable block 4. Since the movable rod 5 is tilted upward from back to front, when the movable block 4 moves forward and backward, the support plate 31 is driven to rotate along the fixed shaft 32 through the movable rod 5 to adjust the inclination angle of the work surface assembly 3.

[0029] When it is necessary to rotate the drawing on the rotating table 33, the pull rod 3410 is pulled outward, and the pull rod 3410 pulls the movable plate 348 and the movable shaft 345 outward through the straight rod 346. The movable plate 348 squeezes the spring 349 to move outward, and the movable shaft 345 pushes the two limit clamps 343 to expand through the two connecting rods 344, disconnecting the meshing of the two limit clamps 343 and the gear 342, so that the rotating table 33 can be rotated. When the rotating table 33 rotates, it drives the rotating shaft 35 and the gear 342 to rotate synchronously, and the universal ball 36 on the bottom end surface of the rotating table 33 moves along the top of the support plate 31 The surface is rolled, and the support effect at the edge of the rotating table 33 is increased by the universal ball 36. After the rotating table 33 is rotated to the required angle, the pull rod 3410 is released, and the elastic potential energy generated by the spring 349 pushes the movable plate 348 to move to the right. The movable plate 348 drives the movable shaft 345 to move to the right through the straight rod 346, and the movable shaft 345 pulls the two limit clamps 343 to contract through the two connecting rods 344, so that the right ends of the two limit clamps 343 are engaged with the upper and lower sides of the gear 342, thereby limiting the rotation of the gear 342, thereby preventing the rotating table 33 from rotating easily and affecting the designer's drawing.
