[0007] Preferably, a cutting groove is formed on the upper surface of the cutting base plate directly below the cutting body.

[0008] Preferably: the elastic component includes a fixed cylinder, a spring body and a movable column, the fixed cylinder is fixed to the lower surface of the reciprocating block, the spring body and the movable column are both movable inside the fixed cylinder, one end of the spring body is movably connected to the inside of the fixed cylinder, the other end of the spring body is movably connected to one end of the movable column, and the other end of the movable column passes through the fixed cylinder and extends to the bottom of the fixed cylinder and is fixedly connected to the top of the locking knife block.

[0009] Preferably, a frosted layer is embedded in one side of the extrusion block that contacts the cutter body and an inner wall of the locking groove.

[0010] Preferably, a hemispherical stabilizing block is provided on the side of the reciprocating block.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] By arranging an elastic component, the elastic component presses the cutting knife block and the cutting knife body downward, so that they have sufficient pressure to cut the light guide plate. If a hard object is encountered, the cutting knife body will be squeezed upward, and the cutting knife body will move upward through the cutting knife locking groove to drive the elastic component to contract, thereby preventing the cutting knife body from being squeezed, broken and splashed after hitting a hard object. The effect of shrinking the cutting knife body after hitting a hard object to avoid the cutting knife body breaking is achieved, and the problem of the existing cutting knife breaking and splashing when hitting a hard object during cutting, which may cause danger to the staff, is solved.
