Embodiment Construction

[0028] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.

[0029] Such as figure 1 As shown, this embodiment provides a pencil lead smoothing device, which is composed of a base module 1 , a clamping module 2 and a buffer module 3 . The buffer module 3 is installed in the center of the base module 1, and the clamping module 2 is installed above the base module 1, and the pencil 4 to be smoothed passes through the clamping module 2 and the buffer module 3 in turn and is exposed from the bottom plane of the base module 1 , the pencil 4 is fixed by the clamping module 2 . When the smoothing device is placed on the grinding plane, the lead head...

Abstract

The invention relates to a pencil lead smoothening device which comprises a base module, a clamping module and a buffering module, an outlet hole is formed in the bottom plane of the base module, the buffering module is arranged in the base module, the clamping module is installed on the buffering module, and a pencil with a pencil lead head to be smoothened is fixed through the clamping module. One end of the pencil lead head penetrates through the outlet hole, the pencil lead head is perpendicular to the plane of the outlet hole, after the pencil lead head is subjected to external force, the pencil drives the buffer module to be compressed through the clamping module, and the pencil and the clamping module move upwards together. Compared with the prior art, the device is easy to operate, the flatness of the ground pencil lead is ensured, and the accuracy of a subsequent material hardness test is conveniently improved.

Description

technical field [0001] The invention relates to the field of pencil hardness testing, in particular to a pencil lead grinding device. Background technique [0002] Pencil Hardness Tester is a device to measure the hardness of coating film and material surface (such as ABS, PC / ABS) with the hardness mark of pencil. It is small in size and light in weight, which is convenient for hardness measurement in laboratories and construction sites. Before using the pencil hardness tester, the lead head of the pencil needs to be ground to ensure the accuracy of the test. At present, most of the grinding of the pencil refill head is purely manual. The user directly holds the pencil and grinds the refill head on a flat surface such as a sand surface to form a plane. As a result, the accuracy of the subsequent hardness test is affected. Contents of the invention [0003] The object of the present invention is to provide a pencil lead smoothing device in order to overcome the above-ment...
