The user can thread the first protective shell 5, the second protective shell 6 and the third protective shell 7 at the inner end of the protective cover 2 to the outer end surface of the tool handle 11 in the tool body 3 through the center groove 9 to realize the jacket-type design of the tool handle 11, which helps to protect the tool handle 11 and prevent damage to the center tool handle 11 during the rotation of the tool handle 11. A spring frame 10 is provided in the center of the first protective shell 5, the second protective shell 6 and the third protective shell 7 for absorbing stress to prevent direct contact with the mold part and damage when the tool head 12 is erroneously operated. The setting of the spring frame 10 effectively absorbs the residual buffering force.

[0021] The blade body 3 is sleeved on the inner end of the center groove 9 through the blade handle 11, and the spring frame 10 between the first protective shell 5, the second protective shell 6 and the third protective shell 7 at the inner end of the protective cover 2 has the ability of elastic deformation. The front end position of the blade holder 14 at the inner end of the blade head 12 adopts a conical structure. The center groove 9 passes through the interior of the first protective shell 5, the second protective shell 6 and the third protective shell 7. The first protective shell 5, the second protective shell 6 and the third protective shell 7 adopt a three-stage design. By installing the blade head 12, the reinforcement 15 at the inner end of the blade head 12 adopts a thickened setting, which can effectively reduce the wear of the front end part, making the blade head 12 more durable to use, and the blade handle 11 and the blade head 12 are integrally formed, which is convenient for quick installation.
