A cutter is arranged below each pair of strip holes 3a, the cutter comprises a rectangular cutter seat 4 distributed along the width direction of the movable plate 3, and a blade 4a is connected to the side wall of one side of the cutter seat 4 through a pin 4 d. Two strip holes 3a at the top end of the tool apron 4 are respectively provided with a bolt 4b in a penetrating way, the lower end of the bolt 4b is in threaded connection with the top end of the tool apron 4, and a locking sheet 4c with the diameter larger than the width of the strip hole 3a is sleeved on a screw rod of the bolt 4b above the strip hole 3a in a penetrating way. By screwing the bolt 4b, the top cap 4e at the top end of the bolt 4b moves downwards, and then the locking piece 4c is pushed to extrude the upper surfaces of the movable plates 3 at the two sides of the strip hole 3a, so that the tool apron 4 is locked at a proper position below the strip hole 3 a.
When the tool apron 4 is moved as required, the top cap at the top end of the bolt 4b is moved upwards when the screwing bolt 4b needs to be reversely twisted, and then the locking piece 4c is loosened, so that the tool apron 4 can be manually pulled to move to a proper position below the strip hole 3a, and then the top cap locking piece 4c at the top end of the bolt 4b is screwed.
A pressing plate 6 with the shape corresponding to that of the movable plate 3 is arranged below the movable plate 3, a group of second guide pillars 6b is fixedly connected to the pressing plate 6, the upper ends of the second guide pillars 6b penetrate through the movable plate 3 and then are fixedly connected with top caps 6c correspondingly matched with the movable plate 3, and springs 6d are sleeved on the second guide pillars 6b between the movable plate 3 and the pressing plate 6.
The pressing plate 6 below each pair of the strip holes 3a is provided with a through hole 6a which is distributed correspondingly. The length of the 6a is slightly larger than that of the elongated hole 3a, and the width is slightly larger than that of the tool apron 4. A first spacer 8 is bonded to the bottom surface of the platen 6.
A group of cutter grooves 7 correspondingly matched with the blades 4a are arranged on the bottom plate 1a below each through hole 6a, and abdicating holes 9a distributed with the through holes 6a are arranged on the second gasket 9.
A long limiting block 9b is respectively bonded on the second gasket 9 at the outer side of each abdicating hole 9a, a group of slots 9c are arranged on the long limiting block 9b, and the slots 9c are distributed at intervals, so that the outer shape of the long limiting block 9b forms a buttress structure.
A left material guide strip 10 is arranged on the second gasket 9 on the left lower side of the pressing plate 6, and a right material guide strip 11 is arranged on the second gasket 9 on the right lower side of the pressing plate 6.
