The tool holder fixing strip 614 adjusts its own position by the sliding mode of the sliding blocks 613 and the sliding round rods 611, facilitating the adjustment of the width between the two tool holder fixing strips 614 and installing different specifications of cutting tools 627 to adapt to sheets of different widths.

[0028] The spliced tool holder 62 includes two tool seats 621. Sliders 622 are fixedly provided at both ends of the tool seats 621. Limit blocks 623 are fixedly provided on both sides of the tool seats 621. The spliced tool holder 62 further includes two clamping plates 624. Sliders 622 are also provided at both ends of the clamping plates 624. A limit groove 625 is provided on one side of the clamping plates 624. The limit blocks 623 are embedded inside the limit groove 625. The sliders 622 are slidably connected to the chutes 615. Two clamping plates 626 are provided above the clamping plates 624. A cutting tool 627 is provided inside the tool seats 621. The tool seats 621 and the cutting tool 627 are connected by buckles and screws. When the width between the tool holder fixing strips 614 increases, only a wider clamping plate 624 needs to be replaced to support the two tool holder fixing strips 614 on both sides, and then the cutting tool 627 is replaced with a wider cutting tool 627 and snapped into the tool seats 621. Since the tool seats 621 are spliced, there is no need to replace the tool seats 621.

[0029] Reinforcing slots 6261 are fixedly provided at the tops of the two clamping plates 626. Reinforcing bars 6262 are inserted inside the reinforcing slots 6261.

Reinforcing slots 6261 are provided on the clamping plates 626 and connected by the reinforcing bars 6262. When the width between the tool holder fixing strips 614 increases, the relative positions of the reinforcing slots 6261 and the reinforcing bars 6262 are adjusted to adjust the distance between the two clamping plates 626, enabling the clamping plates 626 and the tool holder fixing strips 614 to be adjusted synchronously.

[0030] The oil pump assembly 4 includes a drive seat 41. The drive seat 41 is connected to the lower machine base 2 by screws. At both ends of the drive seat 41, there are respectively an electric motor 42 and an oil pump 43. The input end of the drive seat 41 is connected to the output end of the electric motor 42, and the output end of the drive seat 41 is connected to the input end of the oil pump 43. The electric motor 42 converts kinetic energy through the drive seat 41 to supply energy to the oil pump 43.

[0031] The oil cylinder assembly 5 includes two oil cylinder barrels 51. Above the oil cylinder barrels 51, there is an installation seat 52 which is connected by screws. The installation seat 52 is connected to the top of the lower machine base 2 by screws. Above the installation seat 52, a supplementary oil cylinder 53 and a full oil valve 54 are installed and connected by screws. Below the oil cylinder barrels 51, there is a cross beam 55. The cross beam 55 is connected to the inner wall of the lower machine base 2 by screws. Two connecting rods 56 penetrate through the cross beam 55. There is a bushing 57 outside the connecting rods 56. The bushing 57 passes through the lower machine base 2 and is connected by screws. The top ends of the connecting rods 56 are connected to the upper machine base 1 by screws. The oil cylinder barrels 51 and the inner telescopic rods press against the cross beam 55 to drive the upper machine base 1 to vertically lift and lower.

[0032] The linkage mechanism 7 includes four groups of elbow plates 71. The four groups of elbow plates 71 are divided into two pairs with different opening directions. Between a pair of elbow plates 71 with the same opening direction, they are connected by a rotating rod 72 and screws. The two ends of the rotating rod 72 are rotatably connected to the lower machine base 2. Between two elbow plates 71 on the same side with different opening directions, they are connected by a straight rod and a rotating shaft. At the bottom end of the connecting rod 56, there is a fixed turning connector 73. The turning connector 73 is turnably connected to the elbow plate 71 by a short rod and a rotating shaft. The elbow plates 71 and the straight rod balance the forces transmitted from the connecting rods 56 and the turning connector 73 at both ends, so that the upper machine base 1 reaches a steady state during lifting and lowering, avoiding deviation.

[0033] Working principle: When the present utility model is in use, place the XPE sheet on the cutting table 8. The oil cylinder barrels 51 and the inner telescopic rods press against the cross beam 55 to drive the upper machine base 1 to vertically lift and lower, driving the splicing tool holder 62 to press down, so that the cutter 627 cuts the XPE sheet.

[0034] When the width of the XPE sheet changes, the tool holder fixing strip 614 adjusts its own position by sliding the sliding block 613 along the sliding round rod 611, facilitating the adjustment of the width between the two tool holder fixing strips 614, and installing cutters 627 of different specifications to adapt to sheets of different widths. When the width between the tool holder fixing strips 614 increases, only need to replace a wider clamping plate 624 to support the two tool holder fixing strips 614 on both sides, and then replace the cutter 627 with a wider cutter 627 and snap it into the tool holder 621. Since the tool holder 621 is spliced, there is no need to replace the tool holder 621.
