The equal fixed mounting in upper end of four lift posts 10 has interlock piece 9, the interlock board 8 has been cup jointed in the activity on four lift posts 10, the downside and the 11 upside laminating of lifter plate of interlock board 8, handheld interlock board 8 is with its rebound, when the movable plate 8 removed four interlock pieces 9, continue rebound interlock board 8, thereby can drive four interlock pieces 9 rebound simultaneously, just so you can drive four lift posts 10 rebound simultaneously, loosen interlock board 8, will the rebound through four lift posts 10 of the reason of gravity, thereby convenient user removes four lift posts 10 simultaneously, can improve staff's work efficiency like this.

Spacing groove 38 has all been seted up to the lower extreme of four lift posts 10, equal swing joint has gag lever post 3 in four spacing grooves 38, four gag lever posts 3 move about respectively and run through four connecting plates 6, the lower extreme of four gag lever posts 3 respectively with four hemisphere pieces 2 fixed connection, four pressure spring a4 are interactive respectively and cup joint on four gag lever posts 3, four lift posts 10 downstream, when four hemisphere pieces 2 contact the article that need the cutting, four lift posts 10 continue the downstream, four gag lever posts 3 will remove in four spacing grooves 38 respectively, can guarantee through gag lever post 3 that pressure spring a4 can not warp all around when exerting pressure downwards, thereby prevent that four hemisphere pieces 2 from the article that need the cutting from going up the fixed effect that the landing influences the device.

In use, the first step: the four lifting columns 10 move upwards firstly, then the articles to be cut are placed on the placing plate 35, then the four lifting columns 10 are loosened, so that the four lifting columns 10 can move downwards due to gravity, the rotating rods 18 can be contacted at multiple points according to the shapes of different articles, then the rotating rods 18 are rotated clockwise, so that the rotating rods 16 are rotated at multiple points through the connecting strips 17, and then the two gears a15 can be driven to rotate, so that the two racks 12 can be conveniently driven to move downwards, the lifting plates 11 can be driven to move downwards, the trapezoidal blocks 34 are driven to move downwards, because the front sides of the fixing plates 39 are attached to the inclined surfaces of the trapezoidal blocks 34, the trapezoidal blocks 34 can move forwards, when the rear sides of the trapezoidal blocks 34 are attached to the fixing plates 39, the four lifting columns 10 can be fixed by the trapezoidal blocks 34, then the rotating rods 16 are continuously rotated clockwise, so that the lifting plates 11 are continuously driven to move downwards, just so can drive lift post 10 downstream to drive four connecting plates 6 downstream, just so can exert pressure to four pressure spring 4, thereby exert pressure to four hemisphere pieces 2 respectively, just so can fix the article that needs the cutting, thereby can fix as required the shape of cutting article, the article that can be applicable to multiple shape like this are fixed.

The second step is that: through the rotation of the rotating rod 16, the screw 33 can be driven to rotate through the driving belt a19, so that the two moving strips 36 are driven to move, because the threads of the left section and the right section of the screw 33 are opposite, the two screws move in opposite directions when moving, and thus when the rotating rod 16 drives the four lifting columns 10 to move downwards to fix the articles to be cut, the two moving plates 21 move in directions close to each other, so that the articles to be cut can be fixed from two sides of the articles to be cut, and thus the fixing effect of the device on the articles can be improved.

The third step: when the two moving plates 21 move towards the direction close to each other, the two pressure plates 24 are respectively driven by the two pressure springs b20 to move towards the direction close to each other, so that the two pressure plates 24 apply pressure to the article to be cut and fix the article to be cut, and the article to be cut can be fixed, and meanwhile, the article to be cut can not be damaged due to the toughness of the pressure spring b 20.

The fourth step: through when two pressure plates 24 move to the direction that is close to each other to can drive two and remove pipe 23 and remove to the direction that is close to each other, just so can drive two laminating and take 25 to the direction that is close to each other and remove, thereby two laminating are taken 25 and just can be with the article left and right sides laminating that needs the cutting, just so can increase the fixed effect of article to needs the cutting.

The fifth step: can drive the rotation of column a32 rotatory through drive belt b27 through the rotation of rotary rod 16 to it is rotatory to drive change gear 31, just so can drive gear b30 rotatory, thereby column b29 is rotatory, just so can drive rotatory fan 26 rotation and produce wind-force, thereby can blow off the dust that cuts the production on placing board 35 or the dust that falls, can clear up placing board 35 like this, and thus to placing board 35 when using the device at every turn clear up, improve the practicality of device like this.

And a sixth step: move it upwards through handheld interlock board 8, when the movable plate 8 moved four interlock pieces 9, continue upwards to move interlock board 8 to can drive four interlock pieces 9 simultaneously and upwards move, just so can drive four lift posts 10 simultaneously and upwards move, loosen interlock board 8, four lift posts 10 will move downwards through the reason of gravity, thereby convenience of customers removes four lift posts 10 simultaneously, and this kind can improve staff's work efficiency.

The seventh step: through four lifting columns 10 downstream, when four hemisphere piece 2 contacted the article that needs the cutting, four lifting columns 10 continued downstream, and four gag lever post 3 will remove to four spacing groove 38 respectively, can guarantee through gag lever post 3 that pressure spring a4 can not turn round all around when exerting pressure downwards to prevent that four hemisphere piece 2 from influencing the fixed effect of device from the landing on the article that needs the cutting.

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.
