Problems solved by technology
[0004] The above-mentioned patent drives the turbine (roller) to rotate through the transmission disc to drive the friction wheel (impeller) to rotate and then pushes the pencil to move when the pencil is inserted. However, when the transmission disc drives the turbine to rotate, it is easy to cause the roller (turbine) to deviate. When the turbine) is offset, the shaft is prone to jamming, which leads to unreliable rotation of the roller (turbine or gear), which in turn affects the automatic feeding of subsequent pencils

The invention relates to a pencil feeding mechanism of a pencil sharpener and the pencil sharpener, and the pencil feeding mechanism of the pencil sharpener comprises: a support seat which is provided with an opening; at least two groups of rotating assemblies which are arranged at intervals, wherein each rotating assembly comprises a rotating shaft, a gear and a rotating wheel, the rotating shaft can be rotationally arranged on the support, the gear and the rotating wheel are arranged on the peripheral wall of the rotating shaft and rotate together, a gap is defined by the rotating wheels, and the gap is located on the downstream of the opening in the pen feeding direction; the pen feeding mechanism is characterized by further comprising an actuating cover which is arranged on the support and arranged to rotate relative to the support, wherein the actuating cover is located on the periphery of the rotating assembly, a through opening is formed in the position, corresponding to the gap, of the actuating cover, and the through opening is located on the downstream of the gap in the pen feeding direction; and at least one pushing part for driving the gear to rotate is arranged on the inner circumferential wall of the actuating cover, and the pushing part is meshed with the gear. And the situation that the rotating shaft is stuck due to gear deviation is prevented, and the reliability of gear rotation is improved.
Description
technical field [0001] The invention belongs to the technical field of pencil sharpeners, and in particular relates to a pen feeding mechanism of a pencil sharpener and a pencil sharpener. Background technique [0002] The pencil sharpener includes a housing and a cutting mechanism, and the pencil is cut by manually driving the cutting mechanism to rotate. [0003] The pen feeding mechanism of the current pencil sharpener, such as the Chinese utility model patent "The Automatic Pen Feeding Mechanism of the Pencil Sharpener", its patent No. is ZL201922498883. The pen mechanism includes a first pen feed assembly, a second pen feed assembly and a turbine, the first pen feed assembly and / or the second pen feed assembly includes an impeller meshed with the turbine, and the teeth of the impeller can move left and right in the turbine and transmit the turbine rotating torque to the impeller. Another example is the Chinese utility model patent "Pen Sharpening Machine Pen Feeding D...
