The power tool 100 is capable of responding to a specific angle value set by the user's operation, and starts to start when the tilt angle value of the power tool 100 is equal to the set specific angle value. The electric power tool 100 may be an electric screwdriver, an electric drill, an electric scissors, or the like. In the present embodiment, the power tool 100 includes a sensing device 10, an input device 20, a memory 30, and a processor 40.

The sensing device 10 is disposed on the power tool 100 for detecting the current tilt angle of the power tool 100. The current tilt angle of the power tool 100 includes an angle between the power tool 100 and the tilt angle of the power tool 100. For example, the current angle of the power tool 100 relative to the horizontal plane is forty-five degrees, the tilt direction. The angle value is 30 degrees north to north. In the present embodiment, the sensing device 10 includes an electronic compass disposed on the power tool 100 and one or more gravity sensors for detecting the power tool 100 relative to a horizontal plane. The angle of the electronic compass is used to detect the direction in which the power tool 100 is tilted. In the present embodiment, a plurality of gravity sensors may be distributed in different orientations of the power tool 100 along the housing of the power tool 100. For example, the sensing device 10 includes three gravity sensors, and the three senses of gravity The detectors are respectively located at both ends and the center of the power tool 100. In other embodiments, the sensing device 30010 can also include a tilt sensor and an electronic compass disposed inside the power tool 100. The use of a gravity sensor or a tilt sensor to measure the angle of an object with respect to a horizontal plane and the use of an electronic compass to detect the tilting direction of an object are common technical means in the art, and thus will not be described herein.

Please refer to FIG. 2 for a schematic diagram of the functional modules of the startup control system 200 in an embodiment of the present invention. The start control system 200 operates in the power tool 100. In an embodiment, each functional module in the startup control system 200 is a hardware unit that is solidified in the processor 40. In other embodiments, the startup control system 200 is a program module stored in the memory 30 and is called by the processor 40 to execute.

The condition setting module 21 is configured to set a value for a specific angle value. In the present embodiment, the specific angle value includes an angle with respect to a horizontal plane and a direction of inclination required for the tilt angle of the electric power tool 100 during use. In the embodiment, the input device 20 is a condition setting switch for the user to operate. As shown in FIG. 3, when the condition setting switch is turned on by the user, the user can place the power tool 100 on the object to be operated. The position of the power tool 100 to be tilted during use is determined, for example, the position of the screw hole of the power tool 100 to be screwed. The sensing device 10 detects the current tilt angle of the power tool 100. The module 21 acquires the current tilt angle of the power tool 100 detected by the sensing device 10, and sets the tilt angle of the currently obtained power tool 100 to the specific angle when the user turns off the condition setting switch. The value is stored in the memory 30 for the set specific angle value.

It can be understood that in other embodiments, the input device 20 can also be an input device such as a button or a touch screen disposed on the main body of the power tool 100. For example, as shown in FIG. 4, the user can directly pass the input device 20. The setting of the specific angle value is directly input, and then the condition setting module 21 acquires a specific angle value set by the user through the input device 20 and stores the specific angle value to the memory 30. For example, if the power tool 100 is an electric screwdriver, the user can pass the electric screwdriver when a screw needs to be locked into the product at an angle of forty-five degrees with respect to the horizontal direction and the inclination direction is thirty degrees to the north. The input device such as the keyboard directly inputs the specific angle value to be inclined at forty-five degrees with respect to the level, and the tilt direction is thirty degrees to the north.

The comparison module 22 is configured to compare the set specific angle value acquired by the data acquisition module 21 with the current tilt angle value of the power tool 100, and determine whether the current tilt angle of the power tool 100 is different from the set specific angle. The values are the same.

The control module 23 is configured to send a trigger signal to control the power tool 100 to start when the comparison module 22 determines that the current tilt angle value of the power tool 100 is the same as the set specific angle value. In the present embodiment, the start of the power tool 100 means that the power tool 100 starts the operation of locking the screw, punching, and the like. For example, if the electric power tool 100 is an electric screwdriver, the electric screwdriver includes a screwdriver head and a motor for driving the screwdriver head, and the control module 23 controls the power tool 100 to be activated by: the control module 23 is in the comparison module. When it is determined that the current tilt angle value of the power tool 100 is the same as the specific angle value set by the user, a trigger signal is sent to the motor in the power tool 100, and the power of the trigger motor is turned on, so that the motor starts to drive the starter head to rotate. Perform the lock screw operation. When the comparison module 22 determines that the current tilt angle value of the power tool 100 is different from the specific angle value set by the user, the control module 23 controls the power tool 100 not to start.

In an embodiment of the present invention, the power tool 100 further includes a switch 50. When the switch 50 is turned on by the user, if the user turns on the power of the power tool (not shown), the sensing device 10 and the start control system 200 begins to operate, the power tool 100 starts to start when the tilt angle is the same as the set specific angle value. When the system control switch 50 is turned off by the user, the sensing device 10 and the start control system 200 do not work, and the power of the power tool 100 is started by the user after being turned on.

In an embodiment of the present invention, the power tool 100 further includes a prompting device 60. After the condition setting module 21 completes the setting of the specific angle value, the condition setting module 21 passes the specific angle value through the prompt mode. Group 60 prompts the user to inform the user that the specific angle value setting is complete. The control module 23 is further configured to output the current tilt angle value of the power tool 100 acquired by the data acquisition module 21 with respect to a horizontal plane and a specific angle value set by the user to the user through the prompting device 60, so that the user is more easily grasped. The angle of inclination of the power tool 100. The prompting device 60 can be a display screen, a speaker, or the like.
