When needing to take out desktop out of rectangle deckle board 2 that match, people can be to the first mandril 32 and the second top Bar 35 pushes up, and the first limit plate 33 and the second limit plate 36 are respectively that the first mandril 32 and the second mandril 35 provide limit, It can prevent the first mandril 32 and the second mandril 35 from deviating from out of the first pilot hole 311 and the second pilot hole 341 respectively, when first When mandril 32 and the second mandril 35 push upwards, the first mandril 32 and the second mandril 35 can push up desktop out of rectangle deckle board 2 Out, dress is carried out to desktop convenient for people to take, it is easy to use.

When needing simultaneously to act the first mandril 32 and the second mandril 35, people can be held holding rod 48, and Reel 44 is rotated by holding rod 48, to be wound to bracing wire 43, bracing wire 43 can be led reel 44 first Sliding in string holes 411 and the second wire guide 421, and first is driven simultaneously by the first small guide plate 41 and the second small guide plate 42 Mandril 32 and the second mandril 35 are moved upwards, not only operate investment that is more convenient, and reducing artificial.

After reel 44, which is wound into bracing wire 43, sets fixing turn, the first mandril 32 and the second mandril 35 can by desktop from Ejection in rectangle deckle board 2, then people again screw big screw rod 54, and big screw rod 54 is to drive arc pressuring plate 51 to transport downwards It is dynamic, and arc pressuring plate 51 is tightly pressed on reel 44, so that reel 44 firmly be fixed, tension spring 52 is arc Pressing plate 51 provides pulling force auxiliary.

Swingle 62 can rotate in casing 61 at this time, and swingle 62 is incited somebody to action to drive small pressing plate 63 to be rotated Small pressing plate 63 turns to the top of rectangle deckle board 2, and is kept off desktop in rectangle deckle board 2 by small pressing plate 63, more safe It is firm.

The above description is only an embodiment of the present invention, is not intended to limit the scope of the invention, all to utilize this hair Equivalent structure or equivalent flow shift made by bright description is applied directly or indirectly in other relevant technology necks Domain is included within the scope of the present invention.
