Detailed Description

The following description of the embodiments of the present invention will be made in detail with reference to the accompanying drawings 1 to 9.

The driving device can adjust the two cross blocks at the left side and the right side to be relatively far away or close to each other, so that the vertical rods 5 at the left side and the right side are relatively far away or close to each other, the distance between the vertical rods 5 at the left side and the right side is adjusted to a proper distance to be matched with the demonstration white boards 24 with different width specifications, so that the demonstration white boards 24 can be fixed through the clamping plates 8, the screw rods 9, the fixing devices and the like, the vertical adjusting device can drive the two fixing blocks 7 on the same vertical rod 5 to be relatively close to or far away, so that the fixing devices can be matched with the demonstration white boards 24 with different height specifications, the fixing devices can fix the demonstration white boards 24 with different widths and heights through the coordinated adjusting driving device and the vertical adjusting device, and the fixing devices can fix the demonstration white boards 24 by rotating the driving plates 23 to drive the screw rods 9, is convenient to use. And when using, the fixing device of the two cross sliding blocks 4 front end can be the fixing device commonly used, the fixing device of the two cross sliding blocks 4 rear end can be the reserve fixing device, when the fixing device commonly used is damaged, the reserve fixing device can be used, the reserve fixing device is completely the same as the fixing device commonly used, the following will describe with the fixing device commonly used.

When using this device to demonstrate the installation of blank 24, can make fixing device can be with the demonstration blank 24's of corresponding specification width looks adaptation through adjusting drive arrangement earlier, specifically be: through the second motor 16 in the forward rotation or reverse rotation vertical cylinder 2, the second motor 16 will drive the driving rod 17 to rotate forward or reverse, and at this time, with the rotation of the driving rod 17 and the limiting effect of the mutual matching between the upper lug 19 and the lower lug 21 and the upper spline and the lower spline 15, the two thread sleeves 18 on the driving rod 17 will approach or move away relatively. Along with the relative approach of the two screw sleeves 18, the upper convex block 19 and the lower convex block 21 respectively drive the two crosshead shoes 4 to move along the corresponding guide rails 3 through the upper pull rod 20 and the lower pull rod 22, and the two crosshead shoes 4 are relatively far away, at this time, the distance between the left vertical rod 5 connected with the crosshead shoe 4 and the right vertical rod 5 connected with the crosshead shoe 4 is also increased, that is, the distance between the left fixing device and the right fixing device is increased, when the demonstration whiteboard 24 is fixed, the left fixing device is used for fixing the left side of the demonstration whiteboard 24, and the right fixing device is used for fixing the right side of the demonstration whiteboard 24, in conclusion, the two screw sleeves 18 are relatively close to enable the fixing device to fix the demonstration whiteboard 24 with a larger width; correspondingly, as the two screw sleeves 18 are relatively far away, the distance between the fixing device on the left side and the fixing device on the right side becomes smaller, namely, the two screw sleeves 18 are relatively close, so that the fixing device can fix the demonstration white board 24 with a smaller width.

The vertical adjustment device can then be used to adjust the fixture to the height of the demonstration whiteboard 24. The method comprises the following specific steps: the first motor 13 is positively or reversely rotated, the first motor 13 drives the screw 12 rotationally connected with the supporting plate 11 to be positively or reversely installed, so that the two fixing blocks 7 on the screw 12 are driven to relatively approach or separate from each other along the vertical groove 6, along with the relative approach of the two fixing blocks 7, namely, the two fixing devices on the same vertical rod 5 relatively approach each other, namely, the distance between the two fixing devices on the same vertical rod 5 becomes smaller, the fixing devices on the two upper sides are adjusted to be equal in height through the first motor 13, meanwhile, the two fixing devices on the lower side are equal in height, at the moment, the space between the fixing device on the upper side and the fixing device on the lower side is smaller, the demonstration whiteboard 24 with smaller height can be adapted, the two fixing devices on the upper side can fix the upper side of the demonstration whiteboard 24, and the two fixing devices on the lower side can fix the lower side of the demonstration whiteboard 24; correspondingly, as the two fixing blocks 7 are relatively far away, the space between the fixing device on the upper side and the fixing device on the lower side becomes larger, and the demonstration white board 24 with larger height can be adapted. The four fixing devices are arranged at the front end of the crosshead shoe 4, and the relative distances of the four fixing devices can be changed through the driving device and the vertical fixing devices, so that the demonstration white board 24 can be fixed by the four fixing devices.

In securing the demonstration whiteboard 24, the demonstration whiteboard 24 is placed between the four fixtures, and such that the board surface of the demonstration whiteboard 24 is located between the platen 10 and the securing block 7. Then, the screw rod 9 on the clamping plate 8 is driven to rotate by rotating the dial 23, so that the demonstration white plate 24 is pressed by the pressure plate 10, and the demonstration white plate 24 is fixed between the pressure plate 10 and the fixed seat. The bottom plate 1 is arranged to be contacted with the ground to keep the whole stability.
