AI Technical Summary
Existing polishing pens require one hand to hold and the other hand to operate the buttons or sliding switches, which are inconvenient to use, especially when two-handed workpieces are required.
By installing a 3-axis gyroscope on the PCB board of the polishing pen, the posture, displacement and acceleration of the handle are sensed and specific gestures are identified, thereby achieving control over the switching, pause, acceleration and deceleration and rotation direction of the polishing pen.
It realizes grinding pen control without manual operation buttons, improves the convenience and flexibility of operation, and is suitable for situations where workpieces need to be operated with both hands.

Abstract
Description
Technical Field
[0001] The utility model specifically relates to a polishing pen controlled by gestures, and belongs to the technical field of nail art tools. Background Art
[0002] Existing polishing pens all use buttons, sliding switches, knobs (potentiometers or encoders) or foot switches to control the motor, speed and direction. Usually, one hand is required to hold the polishing pen and the other hand is required to operate the buttons, sliding switches or knobs on the polishing pen. In many cases, such as when one hand is already holding the workpiece to be processed or polishing one's own nails, it is necessary to stop the ongoing process and free up one's hands to operate the polishing pen, which is inconvenient to use. A foot switch can free both hands to operate, but the foot switch is relatively bulky and requires additional wiring and space. The pedal of the foot switch also needs to be cleaned regularly, which increases the workload. The foot switch is usually suitable for high-intensity continuous operation scenarios, such as polishing jade.
[0003] Therefore, in view of the deficiencies in the prior art, a grinding pen controlled by gestures is proposed. Utility Model Content
[0004] The purpose of the present utility model is to provide a sharpening pen controlled by gestures in order to solve the above problems, so as to solve the problems raised in the above background technology.

[0006] The utility model installs a 3-axis gyroscope on the PCB board. The built-in 3-axis gyroscope can sense the posture, displacement, acceleration, etc. of the grinding pen handle, thereby recognizing specific gestures, and then realizing the switching, pausing, acceleration and deceleration, and changing the rotation direction of the grinding pen through gestures.
[0007] Furthermore, a battery is installed at the front end of the PCB board.
[0008] Furthermore, the spindle assembly includes a spindle, a clamping seat above the spindle, and a clamping ring and a steel ball arranged on the clamping seat.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] See also Figure 1-Figure 4 As shown, Figure 1-Figure 4 The figure schematically shows a sharpening pen controlled by gestures according to the present invention.
[0020] A grinding pen controlled by gestures, comprising a body 1 and a grinding head 2, wherein the grinding head 2 is arranged at the front end of the body 1, and is characterized in that a PCB bracket 3 is installed inside the body 1, one end of the grinding head 2 is connected to a spindle assembly 6, a motor 5 and a PCB board 4 are installed in sequence from one end of the grinding head 2 inside the PCB bracket 3, and a 3-axis gyroscope 4.1 is installed on the PCB board 4.
[0021] The utility model installs a 3-axis gyroscope 4.1 on the PCB board 4. The built-in 3-axis gyroscope 4.1 can sense the posture, displacement, acceleration, etc. of the grinding pen handle, thereby recognizing specific gestures, and then realizing the switching, pausing, acceleration and deceleration, and changing the rotation direction of the grinding pen through gestures.
[0022] Furthermore, a battery 7 is installed at the front end of the PCB board 4 .
[0023] Furthermore, the spindle assembly 6 comprises a spindle 6.1, a clamping seat 6.2 above the spindle 6.1, a clamping ring 6.3 and a steel ball 6.4 arranged on the clamping seat 6.2.
[0024] The main shaft 6.1 connects the grinding head 2 and the motor 5 together, playing the role of support and transmission.
[0025] Among them, the clamping seat 6.2 is a device for clamping. The grinding head 2 of different specifications can be replaced by adjusting the clamping seat 6.2. The metal ring on the clamping ring 6.3 fixed on the clamping seat 6.2 is used to fix the grinding head 2 and keep the grinding head 2 stable and not loose.
[0026] The steel balls 6.4 are used to reduce the friction between the spindle 6.1 and the grinding head 2, making the entire device more flexible.
[0027] Furthermore, an encoder 8 is installed at the end of the PCB board 4 .
[0028] The encoder 8 is used to detect the rotation speed and direction of the spindle, and plays a role in monitoring and regulation.
[0029] Furthermore, it also includes a front handle 11 and a rotating sleeve 12 installed on the front handle 11 , and the main shaft assembly 6 is installed in the front handle 11 .
[0030] Furthermore, a screen 9 and buttons 10 are installed on the body 1 .
[0031] Furthermore, a rear cover 13 is installed at the rear of the fuselage 1 .
[0032] In the present invention, the grinding pen is controlled by the following gestures:
[0033] When the power of the grinding pen is turned on, quickly shake the handle and the grinding pen will start to rotate;
[0034] Under normal rotation, quickly shake the handle once and the grinding pen will stop rotating; quickly shake the handle twice and the grinding pen will enter the speed adjustment mode: when the handle draws a circle clockwise, the speed of the handle will increase, and when the handle draws a circle counterclockwise, the speed of the handle will decrease;
[0035] Under normal rotation, by inverting the handle of the grinding pen and leaving it alone for 3 seconds, the direction of the grinding pen will be adjusted to the opposite direction.
[0036] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
