Description

Rotary glue removing knife Technical Field The utility model relates to the technical field of aviation sealant construction, in particular to a rotary photoresist removing knife. Background In the aerospace field, the aviation sealant is used as a core material for guaranteeing the structural integrity, safety and reliability of an aircraft, and is widely applied to important scenes such as airframe structural sealing, protection of key parts of an aeroengine, leakage prevention of a fuel system, moisture prevention of an electronic equipment cabin and the like by virtue of the excellent performance of the aviation sealant. However, when the aviation sealant is cured, the photoresist removal work becomes an essential link for subsequent maintenance. Through intensive research and development, most of the traditional manual glue removing modes are difficult to remove glue, a large amount of manpower and time are consumed, the glue removing efficiency is extremely low, the severe requirements of the aerospace field on high efficiency and accuracy of maintenance operation are difficult to meet, and the glue removing mode becomes a big bottleneck for restricting the maintenance process. Disclosure of utility model The present utility model provides a rotary gumming knife to solve the above-mentioned problems in the prior art. In order to solve the technical problems, the utility model adopts the following technical scheme: The utility model provides a rotatory glue removal sword, includes handle and tool bit, the tool bit is connected the one end of handle, the outer wall of tool bit is provided with a plurality of external blades, and is a plurality of external blade sets up along the circumferencial direction equidistance of tool bit, and a plurality of external blade all is the arcuation, external blade's surface is provided with the spatula cutting edge, just the tool bit is kept away from the one end of handle is the sky area. Preferably, the longitudinal section of the handle is plum blossom-shaped. Preferably, the external blade is made of polyoxymethylene hardened materials. Preferably, the cutter head comprises a cylindrical section and a conical section, and one surface of the cylindrical section of the cutter head is connected with one end of the handle. Preferably, the external blades are arranged in four, and the four external blades in an arc shape are arranged from the cylindrical section of the cutter head to the conical section of the cutter head. Preferably, the bottom ends of the four external blades are respectively lower than the bottom end surfaces of the conical sections of the cutter head.
