Embodiment Construction

[0041] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0042] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...

Abstract

The invention relates to an electric tool and electric tool control method. The electric tool consists of a working head, a motor which drives working head to output power, a power supply which provides power for motor, detecting elements which detect the parameter for load of characterization working head and output detection signal, a control module which receives detection signal and controls working head discontinuously output power depending on detection signal to judge the decrease of load for working head. The electric tools, with the situation which the load of working head decreases during the installation process, detecting element can detect the parameter for load of characterization working head changed for the changing of the installing condition of screw, and then output detection signal to control module. Control module discontinuously outputs power depending on the detect sent by detecting element, thereby achieving the goal that monitors screw slip or working head jumps out recessed groove of screw head, changes the working condition of the electric tool and improves the working efficiency in installing screws.

Description

technical field [0001] The invention relates to the field of machining, in particular to an electric tool and a control method for the electric tool. Background technique [0002] With the continuous development of science and technology, electric tools such as screwdrivers for installing screws are increasingly widely used in all walks of life, effectively improving people's work efficiency. And when installing screws with electric tools such as screwdrivers, especially the Phillips screw process, the working head of the electric tool is stuck in the groove of the screw head. In the case of not applying enough downward force to the screw head, it will cause the screw to slip or the processing head to continue to rotate after jumping out of the groove in the screw head, thereby causing damage to the screw or the processing head. [0003] At present, under the above circumstances, the operator can only manually suspend the work of the power tool by observing that the screw s...
