Improved electric hammer

Abstract

The invention relates to an improved electric hammer which is provided with a reference point. The improved electric hammer comprises a tool head for punching, an input module for setting a preset depth, a control module connected with the input module for receiving the preset depth, a distance measuring module for measuring a distance between the reference point and a punched surface and feeding back the distance to the control module for comparing the distance with the preset depth to calculate a current hole depth or a current residual punching depth, a display module connected with the control module to display the current hole depth or the current residual punching depth, and a motor module connected with the control module and controlled by the control module to control whether the tool head works or not. The control module is connected with the distance measuring module and controls the distance measuring module to continue to keep the distance measuring state after the electric hammer punches a hole to the preset depth for the first time so as to provide distance measuring parameters for comparison with the preset depth to ensure that the hole depth is unchanged when the electric hammer continues to work in the current hole direction after the electric hammer is withdrawn by a distance m, wherein m is larger than 0 and smaller than the preset depth. The improved electric hammer effectively improves the working efficiency of a battery.

Description

technical field [0001] The invention relates to the technical field of electric tools, in particular to an improved electric hammer. Background technique [0002] With the development of social intelligence, smart electric hammers have also begun to appear on the market. People can input the desired hole depth through the input module set on the electric hammer, and drill the hole to the depth with the help of the distance measuring module. , at the same time display the hole depth in real time, and after the hole is drilled to the preset depth, the electric hammer will control the motor to stop automatically, so as to achieve precise drilling. [0003] This type of electric hammer improves the drilling efficiency, but there is also a problem. In view of the difference in experience and proficiency, the length of the hole drilled by the operator is not ideal. For example, the hole diameter is slightly smaller than the ideal hole diameter, and the inner wall of the hole is n...

Problems solved by technology

[0004] However, after the existing intelligent electric hammer completes the drilling, the distance measurement function stops working. When the hole is modified, the distance measurement module cannot continue to monitor the distance of the current operation according to the previous preset depth, resulting in During the modification process, it is easy to drill the hole depth beyond the preset depth, resulting in the failure of drilling

[0005] At the same time, whether it is the existing intelligent electric hammer or the previous non-intelligent electric hammer, before drilling, it is necessary to measure and mark the coordinates of the drilling position on the surface to be drilled by means of a ruler before the subsequent drilling can be carried out , but due to the naked eye reading ruler, it is easy to have errors, which can easily lead to inaccurate position finding

[0006] Moreover, the existing electric hammers either only have an intelligent mode or only a manual control mode, which cannot be compatible with both. As a result, once the intelligent mode fails, the motor cannot be automatically controlled to stop, affecting the efficiency of the electric hammer, or lack of experience Or when using the manual control mode to control the electric hammer, it is easy to stop the motor too early or too late, resulting in drilling failure
