Problems solved by technology

However, the stability of manual operation is poor, and the tip of the pen will break if you don’t pay attention; the feed force of the pencil holder cannot be adjusted flexibly, and the pencil holder must be pulled out of the pencil sharpener before planing. These designs cannot guarantee a stable planer. Poor quality and inconvenient to use

Embodiment Construction

[0029] Please refer to figure 1 , a hand-operated pencil sharpener, including a housing, a screw cap 19 with several openings on the top of the housing, a rocker 40 on one side of the housing, a fixing device at the bottom of the housing, and a The pen feeding device 70, the planing device 90 and the waste box 20 are sequentially arranged in the body from top to bottom. To put it simply, in this hand-operated pencil sharpener, the pencil enters the planing device 90 for planing along the vertical pen-feeding path under the action of the pen-feeding device 70 , and the scraps after planing fall into the waste box 20 immediately. When in use, insert the pencil into the opening corresponding to the screw cap 19 and then shake the crank handle 40 to finish planing the pencil and withdrawing the pencil, which reduces the influence of manual work on the pencil planing quality, greatly improves the quality of pencil manual planing and also improves the quality of pencil planing. The...

Abstract

The invention relate to a hand-operated pencil planing, comprising a case, a transmission device arranged in the case and a planing device, wherein, the transmission device is connected with a manual rocking handle and transmits the rotation of the rocking handle on the planing device; a pencil is placed into the planning device along a vertical pencil delivering path for planing. The hand-operated pencil sharpener also comprises a pencil delivering device arranged on the pencil delivering path; the transmission device also comprises a transmission branch used for driving the pencil delivering device; the positive rotation or reverse rotation of the handle leads the inserted pencil to automatically feed in or quit through the linkage of the transmission branch and the pencil delivering device. In the hand-operated pencil sharpener of the invention, the pencil is delivered into the planing device along the pencil delivering path for planing under the action of the pencil delivering device; when the hand-operated pencil sharpener is used, the pencil is inserted into the corresponding opening, thus reducing the influence of manual pencil delivering on the pencil planing quality, greatly improving the pencil manual planing quality and simplifying the structure of the pencil delivering device.

Description

technical field [0001] The invention relates to a pencil sharpener, in particular to a hand-operated pencil sharpener which can automatically send and withdraw pens and plan pencils with different diameters and specifications. Background technique [0002] There are generally two types of pencil sharpeners on the market: electric and manual. Because the frequency of pencil sharpening is not high, it is often in a long-term standby state for electric pencil sharpeners, which not only wastes batteries but is also not environmentally friendly. The corresponding hand-operated pencil sharpener has a large market demand because it does not have a power supply, does not have power consumption problems, and is also lighter and smaller. [0003] Existing hand-operated pencil sharpeners generally only have a planing mechanism, and the crank handle is manually operated, and the transmission device transmits the rotation of the rocker handle to the planing device to plan the nib of the...
