Seal cutting knife placing frame for seal cutting teaching

Abstract

The invention relates to the technical field of art teaching, and discloses a seal cutting knife placing frame for seal cutting teaching. A first rotating rod is rotated, the first rotating rod rotates to drive a sliding plate to move upwards and downwards, and when the sliding plate moves downwards, air located at the bottom of the sliding plate in an adjusting box is extruded, so that a movableplate is driven to block a second vent hole, air on the upper portion of the sliding plate can be prevented from passing through the second vent hole, extruded air can enter a ventilation box througha first air conveying pipe and a second air conveying pipe, air in the second air conveying pipe can be extruded towards the interior of the ventilation box, a blocking ball can be extruded, then airenters a fixing box through a third vent hole, so that the air in the fixing box can move a limiting plate upwards, an adjusting column is driven to move upwards when the limiting plate moves upwards,the seal cutting knife placing frame is adjusted, and the purpose of lifting the seal cutting knife placing frame can be achieved.

Description

Technical field[0001]The present invention relates to the technical field of art teaching, and is specifically a engraved teaching engraving knife placement.Background technique[0002]Engraving art is a calligraphy (mainly a book) and engraving (including chisel, casting), to make seals, is the unique art form of Chinese characters, and the engraving is in the first Qin, Sheng Yahan, dried in the Jin, defeated the Tang, Song, Rejuvenating, Zhongxing, has so far, has been more than 370 years of history, and the knife method is a special manifestation means of engraving art. The seal before the Yuan Dynasty was mostly casting. Even if you need a fake jade, teeth, bone, etc., it is also necessary to use the devices.[0003]According to the search, China Patent No. CN209320570U discloses a engraved teaching engraving knife placement, including the turntable body, and the inner portion of the turntable body is uniformly provided with a clamping device mounting hole for mounting a clamping d...

Problems solved by technology

[0004] In this scheme, although the seal cutting knife used for seal cutting teaching is placed in the fixed clip, the tip of the seal cutting knife will still face downward. If the clamping device of the seal cutting knife is unstable, the seal cutting knife will still fall easily. Injuries are caused by the user, and the height adjustment of the engraving knife holder in this scheme is laborious, so it is not suitable for popularization
