Embodiment Construction

[0022] Such as figure 1 , 2 As shown, the wallpaper cutter of the present invention includes an adjustment driving mechanism 1 , a positioner 2 and a cutter 3 .

[0023] In this embodiment, the cutter 3 is composed of a circular base 31 , four blades 32 , a centering pin 33 and a stud 34 .

[0024] The blades 3 are evenly distributed on the circumference of the bottom surface of the circular base 31, and the blades are along the circumferential direction, so that when driven to rotate, the motion track of the blades is running, thereby cutting out regular circular wallpapers. The blade thickness of the knife of the present invention is 0.3 mm, and the effective blade height is 2 mm ± 0.5 mm, which can ensure the cutting quality and prevent the electric wires and other parts behind the wallpaper from being cut by the blade being too long.

[0025] The central positioning pin 33 is located at the center of the bottom surface of the circular base 31 and is used to rotate the ci...

Abstract

The invention discloses a wallpaper cutter, comprising an adjusting driving mechanism, a positioner, and a cutting tool. The adjusting driving mechanism comprises an adjusting handle and an adjusting main body. The internal of the adjusting main body is hollow. The adjusting handle comprises a holding head and a central spindle. The upper end of the central spindle is connected with the holding head, and the lower end extends into the hollow inner cavity of the adjusting main body. The central spindle is rotatably installed in the hollow inner cavity. The cutting tool is installed on the lower end of the central spindle and rotates synchronously with the central spindle. When the cutting tool rotates, the blade of the cutting tool forms a round motion trail. The positioner is a set of sleeve installed on the adjusting main body. The cutting tool is on the inner side of the positioned. The positioned and the adjusting main body are connected by threads, so that cutting depth of the blade of the cutting tool is adjusted through rotating the positioned. When the wallpaper cutter repairs part irregular damaged positions of a wallpaper, the whole wallpaper does not need to be dismounted, and the wallpaper can be repaired. The wallpaper cutter is beneficial for improving efficiency for repairing part irregular damages of wallpaper in a passenger cabin.

Description

technical field [0001] The invention relates to a wallpaper cutter used in the field of aerospace, which is mainly used in repairing partial damage of wallpaper in aircraft cabins. Background technique [0002] At present, the tools used for aircraft body or component maintenance are generally provided by aviation equipment manufacturers with special part numbers or reference size information provided by maintenance manuals, but the recommendations of these manufacturers cannot cover all links. For example, when the wallpaper in the cabin of an aircraft is partially damaged in a small area, due to the irregular shape of the damaged area, it is difficult, time-consuming and ineffective to repair directly on the wallpaper in the cabin. The current aviation equipment manufacturers or maintenance manuals do not provide or recommend tools with special part numbers to solve this problem. The traditional method is to remove the whole piece of wallpaper, repair it, and then reinsta...
