TECHNICAL FIELD
[0001] The utility model relates to connecting fastener technical field, concretely relates to a kind of anti-loose electric hammer aluminum casting connecting fastener. BACKGROUND
[0002] Electric hammer can produce strong vibration when working, and the vibration can easily cause the connection between aluminum castings to gradually loosen. The anti-loose connecting fastener can enhance the stability of the connection through special structural design or material properties, ensuring that the connection between the aluminum castings and the electric hammer remains tight in a high-vibration environment, avoiding safety hazards and equipment failures caused by loosening.
[0003] The existing technology has the following problems:
[0004] The existing device cannot clamp and fix the aluminum castings during use. When the electric hammer is working, it can produce intense vibration and impact force. If the aluminum castings are not clamped and fixed, they can easily shake or shift during the drilling process, which can cause the drilled holes to be inaccurate in size and smoothness, affecting subsequent installation or processing procedures. In addition, the existing device cannot lock the position of the aluminum castings during the drilling process of the electric hammer. Since the aluminum castings cannot be locked, the instability during drilling can cause the drill bit to unevenly contact the surface of the aluminum castings. Moreover, if the position of the aluminum castings cannot be locked during the drilling process of the electric hammer, the drill bit can deviate from the original drilling position due to the shaking of the aluminum castings, which cannot meet the requirements of hole diameter accuracy for assembly or other subsequent processes.
