Description

Adjusting component of electric pencil sharpener

Technical Field

The invention relates to an adjusting mechanism applied to a pencil sharpener, in particular to an adjusting component of an electric pencil sharpener.

Background

The electric pencil sharpener is characterized in that a motor is arranged on a rotating shaft of a cutter, and the motor drives the cutter to rotate so as to automatically finish the function of sharpening a pencil. The electric pencil sharpener replaces manual operation with the motor, so that pencil sharpening is more convenient. In the process of drawing and writing, pencils with different thick and thin pen points are needed due to personal habits and specified standard requirements. Therefore, the existing electric pencil sharpener is additionally provided with an adjusting component, and the thickness of the pencil point obtained by cutting can be adjusted.

I designed a pencil sharpener capable of adjusting the thickness of a pencil point in 2018 and filed a patent application to the national intellectual property office, and the application (patent) No.: CN 201820973999.1. The pencil sharpener with the structure adopts the structure that the adjusting wheel is arranged on the side surface of the pencil sharpener, and a user moves the gear slide block by rotating the adjusting wheel to change the position of the adjusting surface connected with the pencil blocking block. The up-and-down movement of the pen stopping block realizes multi-gear adjustment of the pen point from thick to thin and from thin to thick. However, in subsequent research and development, the engineers in this department think that the adjusting mode of the side adjusting wheel is not the optimal solution of the adjusting mode of the electric pencil sharpener. Namely, the inventor of the present invention has designed a new adjustment structure and adjustment method.

This is the inoperative state of the adjusting knob 4, i.e. the adjusting knob 4 is rotatably connected to the transmission rod 5.

The adjusting knob 4 is of an inverted T-shaped structure and comprises a bottom plate 4b and an upper support rod 4a, which is a preferred structure of the adjusting knob 4 of the present invention, but the adjusting knob 4 of other structures can also be adopted. The mounting groove is formed in the top surface of the upper support rod 4a, the adjusting knob 4 can move upwards under stress to enable the first gear teeth 7 to be meshed with the second gear teeth 8, and the adjusting knob 4 can rotate to drive the pen stopping block 2 to rotate through the transmission rod 5. The working state of the rotation is adjusted, the adjusting knob 4 is meshed with the transmission rod 5, and the rotation of the adjusting knob 4 drives the pen stopping block 2 to rotate.

Chassis 4b is connected with recess 6 through the spring of compression state, goes up the upper end of branch 4a and wears out chassis 4b, goes up the outer fastener 4c that is equipped with in branch 4a upper end, and 4a upper end lock is in chassis 4b top in the fastener 4c, and adjust knob 4 atress then spring drive returns initial condition. That is, in the non-operating state of the adjustment knob 4, the adjustment knob 4 cannot move downward but can move upward due to the action of the fastener 4 c. The present invention restricts the limit state of the adjusting knob 4 by the fastener 4 c.

Hinder a piece 2 and install in knife rest 9, knife rest 9 includes base 14, and circular notch 10 has been seted up on the base 14 surface, hinders 2 lower parts of 2 axle parts of a piece for installing cylinder 2c in notch 10, and piece 2b is located the top of cylinder 2c, and a plurality of pieces 2b stagger arrangement each other. According to the pen blocking device, the columnar piece is arranged in the notch 10, the notch 10 on one side limits the movement of the columnar piece, and the pen blocking block 2 can only rotate around a shaft and cannot move in other directions. Secondly, can block that the dust after the pencil planing from dropping to the below through notch 10, influence the work of teeth of a cogwheel.

A plurality of clamping grooves 12 are distributed on the periphery of the cylinder 2c, elastic clamping pieces 11 are correspondingly arranged on the tool rest 9, and the pen blocking block 2 rotates to enable the clamping pieces 11 to be embedded into different clamping grooves 12 and to rotate to the lower side of the pen containing bin 1 corresponding to different block pieces 2 b. The user can judge that the pen stopping block 2 is moved in place through the resistance after the card 11 is clamped into the card slot 12. The adjustment of the user is convenient.

The outer surface of the upper end of the transmission rod 5 is provided with a third gear, and the lower end of the shaft element 2a and the lower part of the columnar element are provided with a fourth gear meshed with the third gear. An obliquely arranged leading-out hole 13 is formed in the tool rest 9, and the leading-out hole 13 is positioned below the columnar piece. The guide-out hole 13 is provided for guiding out the dust falling from the notch 10. The knife rest 9 rotates when working, and can guide the dust out through the guide-out hole 13, thereby avoiding influencing the driving part inside the pencil sharpener 3.

The transmission rod is an external rotatable sleeve, the sleeve is connected with a motor and a base of the tool rest, the motor works to drive the tool rest to rotate, a hob (not shown in the figure) is arranged on the tool rest, and the hob rotates around a pencil at a high speed, so that the pencil is planed. The block mounted on the blade carrier will then rotate synchronously with the blade carrier at this time, i.e. the drive rod which engages with the block is also rotating. As such, the present invention provides that the adjustment knob requires a push-up to engage the drive rod to control the rotation of the drive rod, and that the sharpener is inoperative, i.e., the drive rod is not rotating. And under the condition that the adjusting knob is not pushed upwards, the transmission rod and the adjusting knob are in a rotatable state, and the rotation of the transmission rod does not influence the adjusting knob.
