Preferably, top both sides fixedly connected with connecting rod 8 of drawing board 6, the middle swing joint of connecting rod 8 has handle 9, when the user uses device main part 1 to teach, connecting rod 8 of 6 top both sides of drawing board can be fixed the top of drawing board 6, prevent that 6 tops of drawing board from leading to 6 tops of drawing board to warp because the long-time elasticity extrusion of first spring 13, then after the user uses up device main part 1, the user can extrude control first spring through handle 9 in the middle of connecting rod 8, and then will go up drawing board 14 and take in fretwork groove 7, thereby can fold device main part 1, the fixity and the practicality of device main part 1 have been increased effectively.

Preferably, the flexible post 10 of top fixedly connected with of base 2, when the user needs to use device main part 1 to teach, the user can adjust the height of drawing board 6 through the flexible post 10 at base 2 top, and then can let drawing board 6 rise, thereby can satisfy the height that the user needs to teach, then also can reduce the height of drawing board 6 after using up, thereby can reduce the shared space of device main part 1, the adjustability of device main part 1 has been improved effectively.

Preferably, the top of the telescopic column 10 is fixedly connected with a ring block 17, the inside of the ring block 17 is movably connected with a movable block 16, after the front of the drawing board 6 is used up by a user, the user can wipe the drawing board 6 to continue teaching with the drawing board 6, the ring block 17 at the top of the telescopic column 10 rotates around the movable block 16 inside the ring block 17, so that the user can rotate the drawing board 6, the user can continue teaching with the back of the drawing board 6, the time for wiping the drawing board 6 by the user is reduced, the situation that the user needs to use the wiped contents for teaching after the user wipes the contents on the drawing board 6 is also prevented, the user needs to rewrite the contents, the writing time of the user is increased, and the time wasted by the user can be effectively reduced through the arrangement of the ring block 17 and the movable block 16, the convenience of the apparatus main body 1 is effectively increased.

Preferably, by circular recess 3, fixed column 4 and card hole 5 constitute fixed establishment jointly, when the user needs to accomodate device main part 1, the user can shorten the back at flexible post 10, use 2 tops of base fixed column 4 all around to fix drawing board 6 all around, then use with the 3 assorted latch cards in circular recess 3 at the circular recess 4 top, then follow 3 inside callipers of circular recess with the latch in the positive card hole 5 in drawing board 6 both sides, and then fix drawing board 6 on base 6, so be provided with fixed establishment in device main part 1, can accomodate the back at the user with device main part 1, fix device main part 1, increase device main part 1's fastness effectively.

Preferably, when a user needs to use the device body 1 for economic education, and the available area of the drawing board 6 is not enough, the user can pull the upper drawing board 14 out of the hollow groove 7 inside the drawing board 6, and then apply elasticity to the bottom of the upper drawing board 14 through the first spring 13 in the middle of the bottom of the upper drawing board 14, so that the clamping block 12 on the other side of the clamping groove 11 is squeezed towards both sides, and the clamping block 12 can be clamped into the clamping grooves 11 on both sides of the top of the hollow groove 7, so that the pulled upper drawing board 14 can be correspondingly attached to the drawing board 6, and therefore, through the arrangement of the telescopic mechanism in the device body 1, when the use area of the drawing board 6 is not enough, the upper drawing board 14 can be attached to the drawing board 6 by pulling, thereby increasing the use area that the user can write, further, the user can write the contents to be written by himself, and the practicability of the apparatus main body 1 is effectively increased.

The working principle is as follows: firstly, when the user uses device main part 1 to teach, connecting rod 8 of 6 top both sides of drawing board can be fixed the top of drawing board 6, prevent that 6 top of drawing board from leading to drawing board 6 top to warp because the long-time elasticity extrusion of first spring 13, then after the user uses up device main part 1, the user can extrude control to first spring through handle 9 in the middle of connecting rod 8, and then take upper drawing board 14 in fretwork groove 7, thereby can fold device main part 1, the fixity and the practicality of device main part 1 have been increased effectively.

Then, when the user needs to use device main part 1 to teach, the user can adjust the height of drawing board 6 through the flexible post 10 at 2 tops of base, and then can let drawing board 6 rise to can satisfy the height that the user needs to teach, then also can reduce the height of drawing board 6 after using up, thereby can reduce the shared space of device main part 1, improved device main part 1's controllability effectively.

Then, after the user uses up the front of drawing board 6, the user has to wipe drawing board 6, so that the user can continue to use drawing board 6 for teaching, and the ring block 17 at the top of the telescopic column 10 rotates around the movable block 16 inside the ring block 17, and further the user can rotate drawing board 6, so that the user can continue to use the back of drawing board 6 for teaching, the time for the user to wipe drawing board 6 is reduced, and it can also be prevented that the user wipes the content on drawing board 6, the user still needs to use the wiped content for teaching, and the user needs to rewrite, which increases the writing time of the user, so that the time wasted by the user can be effectively reduced through the arrangement of the ring block 17 and the movable block 16, and the convenience of the device main body 1 is also effectively increased.

Next, when the user need accomodate device main part 1, the user can shorten the back at flexible post 10, use 2 tops of base fixed column 4 all around to fix drawing board 6 all around, then use the 3 assorted latch cards in circular recess 3 with the circular recess at fixed column 4 tops, then with the latch card in the positive card hole 5 in drawing board 6 both sides from circular recess 3, and then fix drawing board 6 on base 6, so be provided with fixed establishment in through device main part 1, can accomodate device main part 1 at the user after, fix device main part 1, increase device main part 1's fastness effectively.

Finally, when the user needs to use the device body 1 for economic education, and the user is not enough to the available area of the drawing board 6, the user can pull the upper drawing board 14 out of the hollow groove 7 inside the drawing board 6, and then apply elasticity to the bottom of the upper drawing board 14 through the first spring 13 in the middle of the bottom of the upper drawing board 14, so that the fixture block 12 on the other side of the fixture groove 11 is pressed towards both sides, and further the fixture block 12 can be clamped into the fixture grooves 11 on both sides of the top of the hollow groove 7, so that the pulled upper drawing board 14 can be correspondingly attached to the drawing board 6, therefore, by arranging the telescopic mechanism in the device body 1, when the user is not enough to the available area of the drawing board 6, the upper drawing board 14 can be attached to the drawing board 6, thereby increasing the usable area that the user can write, and further enabling the user to write the content that the user needs to write, the practicability of the apparatus main body 1 is effectively increased.

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.
