Automatic pencil ware of rolling up of special type nib, it includes axle A, axle B, axle C and axle D to roll up a system constitution, axle A axle B axle C with all be connected with the gear on the axle D, axle A axle B axle C with axle D's both ends all are articulated with the box body lateral wall, epaxial gear respectively with epaxial gear B and epaxial gear engagement on the C, epaxial gear and epaxial gear engagement on the D, axle B with axle D's intermediate position all installs the cylinder that has file face structure, is connected with 2 springs between axle B and the axle D.
The automatic pencil sharpener with the special pencil point is characterized in that a pencil inlet is formed in the upper portion of the box body, a sliding groove is formed in the side wall of the rear box body, a rotating shaft is installed in the sliding groove, arc grooves are formed in the side walls of two opposite box bodies inside the box body in a processing mode, the two ends of the shaft D are connected to the inside of the arc grooves respectively, and the side wall of the box body penetrated by one end of the shaft A is connected with a crank handle.
Has the advantages that:
the pencil is fixed through the fixed dental plate, the pencil needs to be cut into a cone, the pencil only needs to be inserted into the pencil sharpener and screwed, the pencil point needs to be cut into an axe shape, the pencil needs to be screwed and shaken, the pencil firstly penetrates through the pencil sharpener and is processed into a conical shape, then the conical pen point enters the pencil rolling system, the rocking handle is shaken to drive the two rollers to rotate in opposite directions under the transmission of the multiple shafts and the gear system, and the conical pen point is ground into the axe shape. The thickness of the axe-type nib processed by the processing machine is controlled by the force of manual insertion into the pencil, the force of inserting the pencil by the axe-type nib with medium thickness is smaller and the distance between the 2 rollers is smaller, the force of inserting the pencil by the axe-type nib with medium thickness is larger and the distance between the 2 rollers is larger, and the non-fixed roller adopted by the bidirectional roller can be automatically adjusted according to the thickness of the lead core, so that the lead core cannot be broken due to over hardness.
