Abstract
A cutting apparatus for cutting a sheet material is provided. The cutting apparatus includes a platform; a rail structure secured onto the platform; a sliding member sliding along the rail structure; a cutting member movably engaging with and carried by the sliding member to pass through and cut the sheet material sustained on the platform; and an adjusting member. The adjusting member can urge the cutting member to move relative to the sliding member so as to contact with the sheet material in response to an external force, and return the cutting member to move relative to the sliding member so as to release the cut sheet material manually or automatically.
Claims19
A cutting apparatus for cutting a sheet material, comprising:
- a platform for sustaining thereon said sheet material;
- a rail structure secured onto said platform;
- a sliding member disposed on and movable along said rail structure;
- a cutting member movably engaging with and carried by said sliding member to pass through and cut said sheet material sustained on said platform;
- and
- an adjusting member urging said cutting member to move relative to said sliding member so as to contact with said sheet material in response to a first external force status and returning said cutting member to move relative to said sliding member so as to release said cut sheet material in response to a second external force status, said adjusting member comprising:
- a knob for receiving an external force in either said first external force status or said second external force status;
- and
- an elastic member interfacing between said knob and said sliding member for returning said knob to an initial position when there is no external force exerted.
A carriage for use with a cutting apparatus for carrying a cutting member to cross over a sheet material, comprising:
- a knob having a sustaining member therein for receiving a rotating force;
- a coupling member having a slot and cooperating with said knob to define a receptacle for accommodating therein said cutting member;
- and
- an elastic member interfacing between said knob and said coupling member for returning said knob to an initial position when said rotating force is released;
- wherein said cutting member is urged by said sustaining member to protrude from said slot to contact with said sheet material in response to said rotating force and be retracted into said coupling member when said knob is returned to said initial position.
A cutting apparatus for cutting a sheet material, comprising:
- a platform for sustaining thereon said sheet material;
- a rail structure secured onto said platform;
- a sliding member disposed on and movable along said rail structure;
- a cutting member movably engaging with and carried by said sliding member to pass through and cut said sheet material sustained on said platform;
- a knob cooperating with said sliding member and having a sustaining member therein for receiving a rotating force to rotate from an initial position to a working position, said sustaining member having a relatively thick portion urging said cutting member to move downwards to contact with said sheet material when said knob is at said working position and having a relatively thin portion providing a space thereunder for said cutting member to retract when said knob is at said initial position;
- and
- an elastic member interfacing between said knob and said sliding member for returning said knob to said initial position when said rotating force is released.
