Description

Technical Field

[0001] The utility model relates to the technical field of electric tools, in particular to a rotatable fixing structure. Background Art

[0002] Power tools are mechanized tools that use electric motors or electromagnets as power and drive the working head through a transmission mechanism to perform operations. They are usually handheld and portable, with a light structure and are easy to carry and use. Compared with hand tools, power tools can increase production efficiency by several to dozens of times, so they have been widely used in various fields of the national economy and have entered household use.

[0003] However, the existing device lacks a device that can conveniently connect and rotate the rotating body with the rotating support frame, which can easily cause the rotating body to be unable to be conveniently connected and rotated with the rotating support frame, resulting in the problem that the entire device cannot be rotated significantly and cannot be conveniently carried when the entire device is used. At the same time, there is also a lack of a device that can slow down the entire device after it rotates to a certain angle, which can easily cause the rotating body and the rotating support frame to collide due to the high speed when the entire device rotates significantly. Therefore, we propose a new device to solve the above problems. Utility Model Content
