Problems solved by technology

[0002] In today's life, many families will have an impact drill for use in daily life, but there are special operating procedures for the use of impact drills. Generally, people who are not familiar with the operating procedures will easily cause accidents when operating impact drills, especially in impact drills. When the drill bit is stuck during the working process, the percussion drill will rotate by itself, and at this time the operator is holding the percussion drill with both hands, and the sudden large torque will cause the operator to be injured

Abstract

The invention discloses an impact drill with a locking protection structure. The impact drill comprises an impact drill main body, an auxiliary handle and a main handle, wherein the impact drill mainbody is provided with an auxiliary handle rotating shaft, an auxiliary handle rotating shaft limiting ring, a main handle rotating shaft and a main handle rotating shaft limiting ring, wherein the main handle rotating shaft is provided with a notch, the auxiliary handle is rotationally arranged on the auxiliary handle rotating shaft on the impact drill main body, and the main handle is rotationally arranged on the main handle rotating shaft on the impact drill main body. According to the impact drill with the locking protection structure, when the impact drill suddenly gets stuck in the operation process, the impact drill main body continues to rotate, the handles held by hands cannot rotate, consequently, people can be effectively prevented from injuring when torsion suddenly generates, thus the impact drill can be safely operated by some people incapable of understanding the operation rules.

Description

technical field [0001] The invention relates to the technical field of percussion drills, in particular to a percussion drill with a stuck protection structure. Background technique [0002] In today's life, many families will have a percussion drill for use in daily life, but the use of percussion drills has special operating procedures. Generally, people who are not familiar with the operating procedures will easily cause accidents when operating percussion drills, especially in the case of impact drills. When the drill bit is stuck during the working process, the percussion drill will rotate by itself. At this time, the operator is holding the percussion drill with both hands, and the sudden large torque will cause the operator to be injured. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the invention provides a percussion drill with a stuck protection structure. [0004] In order to solve the above-mentioned technical problems, the pr...
