Through this arrangement, the limit block 3354 can be pushed to move.

[0026] Here’s how it works:

[0027] First, when using the office table 1 for office work, if the extension plate 31 is needed to assist in office work, the extension plate 31 needs to be taken out from the bottom end of the office table 1;

[0028] Second, pull the extension plate 31. When the extension plate 31 moves, the connecting rod 333 is driven to move by the fixed rod 334. When the connecting rod 333 moves, the sliding block 332 is driven to move, so that the sliding block 332 moves along the sliding groove 331, and the extension plate 31 is brought out of the bottom end of the office table 1.

[0029] Third, when the extension plate 31 moves out of the bottom end of the office table 1, the extension plate 31 is pushed upward. When the extension plate 31 moves, the hinge part 2 3358 is driven to move. When the hinge part 2 3358 moves, the connecting rod 3357 is driven to move. When the connecting rod 3357 moves, the hinge part 1 3356 is driven to move. When the hinge part 1 3356 moves, the movable block 3353 is driven to move, so that the movable block 3353 moves along the fixed plate 3352. When the movable block 3353 moves into the groove of the fixed plate 3352, the spring 3355 loses its force and releases its elastic potential energy to push the limit block 3354 to move. The limit block 3354 moves into the groove of the fixed plate 3352 and is fixed, so that the extension plate 31 can be fixed for use.

[0030] Fourth, after the extension plate 31 is used, the limit block 3354 is pushed upward from the notch at the bottom end of the support plate 3351 to move, so that the limit block 3354 squeezes the spring 3355. When the limit block 3354 moves out of the groove of the fixing plate 3352, the fixing effect on the extension plate 31 is cancelled, and the extension plate 31 can be moved downward. Then, the extension plate 31 is pushed to move the extension plate 31 to the bottom end of the office table 1 and wait for the next use.

[0031] The control method of the present invention is to manually start and stop the switch. The wiring diagram of the power element and the provision of power supply are common knowledge in the field. Moreover, the present invention is mainly used to protect mechanical devices. Therefore, the control method and wiring arrangement are not explained in detail in the present invention.

[0032] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. In addition, the present invention is mainly used to protect mechanical devices, so the control method and circuit connection are no longer explained in detail in the present invention.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
