[0023] In view of this, the present invention provides a pre-cutting device for gasket production. Through the cooperation between the cylinder, the first movable rod and the second movable rod, first, the whole gasket is placed on the top of the workbench, and then the cylinder is started. The output end of the cylinder drives the block to move upward. The first movable rod and the third movable rod rotatably connected to both sides of the block move. The rotation of the third movable rod drives the second movable rod to move through a pin shaft. The second movable rod drives the fixator to move. The bottom of the fixator moves towards the top of the workbench to compact the whole gasket. The rubber pad at the bottom of the fixator can increase the friction with the gasket, realizing that when the cutter contacts the gasket, the gasket will not shift in position on the top of the workbench due to the frictional force generated with the cutter, improving the cutting accuracy.

[0024] By those skilled in the art, the components in this case are connected in sequence.
