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 relates to a hand-operated pencil sharpener, which comprises a casing, a transmission device installed in the casing and a planing device. The transmission device is connected with a manual crank handle and transmits the rotation of the crank handle to the planer device. The pencil enters the planing device along the vertical pen feeding path for planing. The hand-operated pencil sharpener also includes a pen feeding device arranged on the pen feeding path, and the transmission device also includes a transmission branch for driving the pen feeding device. The forward rotation or reverse rotation of the handle automatically feeds or withdraws the inserted pencil through the linkage of the transmission branch circuit and the pen feeding device. In the hand-operated pencil sharpener of the present invention, the pencil enters the planing device under the action of the pen feeding device along the pen feeding path for planing. When in use, the pencil can be inserted into the corresponding opening, which reduces the need for manual feeding of the pencil to plan the pencil. The impact of the quality greatly improves the quality of pencil manual planing and also simplifies the structure of the pen feeding 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...
