Gear type pencil tip thickness adjusting and broken core pushing-out integrated mechanism and pencil sharpener

Abstract

The invention discloses a gear type pencil tip thickness adjusting and broken core pushing-out integrated mechanism which comprises a sliding stop block independently arranged on a knife holder, a telescopic rod only performing axial movement and capable of pushing the sliding stop block to move forward, and a stepped gear disc, wherein at least one gear bar matched with the stepped gear disc is fixedly arranged on the telescopic rod; a driving part capable of rotating the stepped gear disc located inside a rocker arm cover is arranged outside the rocker arm cover; a rear end of the telescopic rod extends out of the rocker arm cover and is staggered with the driving part, so that the rear end of the telescopic rod is exposed outside the rocker arm cover. The gear type pencil tip thickness adjusting and broken core pushing-out integrated mechanism has advantages that the driving part is independent to the rear end of the telescopic rod in spatial position, and the driving part and the telescopic cannot interfere with or affect each other during operation, so as to realize two functions of adjusting the gear type pencil tip thickness and pushing out the broken core.

Description

technical field [0001] The invention relates to a pencil sharpener, in particular to an integrated mechanism of a gear-type pencil core tip on the pencil sharpener with adjustable thickness and broken pencil core pushing out. Background technique [0002] Because the pencil sharpener can sharpen pencils safely and quickly, the pencil sharpener has become an essential tool for students to learn to write. The existing pencil sharpener can cut out pencil nibs of different thicknesses, satisfying students' various uses as writing tools. The Chinese invention patent with the Chinese patent No. 201510200770.5 discloses a pencil sharpener with an adjustable mechanism for the thickness of the pencil core tip and the pencil sharpener, including a sliding stop independently arranged on the tool holder, a rotation button installed on the rocker arm and one end A telescopic rod that is installed in the tool holder and can move axially in the tool holder. The other end of the telescopic...

Problems solved by technology

[0004] Chinese patent No. 201610451378.2 is a gear-type pencil lead tip thickness adjustable mechanism, including a sliding stop independently arranged on the tool holder, a telescopic rod that can move axially and a knob installed on the rocker arm. The telescopic rod can Push the sliding stop to move forward, the middle of the telescopic rod is coaxially fixed with a limit block, the rear end of the telescopic rod behind the limit block extends into the inner hole of the knob, and the limit block is provided with at least one radially extending The gear rib, the front end of the knob is fixed with an annular body, the annular body is provided with at least one multi-level step group, the outer end of the gear rib leans against the multi-level step group, when the knob is turned, the outer end of the gear rib The end moves in a multi-level step group, so that the telescopic rod can move forward and backward, and the gear can be adjusted by turning the rotary button. Before the user uses the pencil sharpener, he can know the gear of the pen core thickness of the pencil sharpener, so that It is easy to control the thickness of the pencil core tip, and the thickness of the pencil core tip is more uniform through gear setting, but this pencil sharpener cannot realize the function of quickly breaking the core and pushing it out
