Cutting finger ring knife

Abstract

The invention provides a cutting finger ring knife. The cutting finger ring knife comprises a finger-ring-shaped body. The outer periphery of the finger-ring-shaped body extends in the radial direction and is bent to form a bent part. The side, opposite to the finger-ring-shaped body, of the bent part is provided with a bayonet. A knife rest plate is detachably connected to the interior of the bayonet. A blade is connected to the knife rest plate through a bolt. A cutting groove is formed between the blade and the outer periphery of the finger-ring-shaped body. An operator arranges the knife on a finger in a sleeving manner, adhesive tape can be dragged into the cutting groove by easily changing the position of the finger, the adhesive tape is cut off through the blade, operation is very convenient, and work efficiency is improved. The blade can be replaced, and cost consumption is substantially reduced. An inner arc concave part and a protruding part which are beneficial to holding and force application are arranged on the finger-ring-shaped body, and the structure is ingenious. The whole knife body is made of plastic materials, and therefore the cutting finger ring knife is light in weight, low in production cost and suitable for being widely popularized.

Description

technical field [0001] The invention relates to an auxiliary tool, in particular to a ring cutting knife.
