[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0030] like Figure 1-Figure 2As shown, the present invention provides a monitor for hand shape correction, characterized in that it includes: a control box 10, wrist straps 40 are respectively provided on both sides of the control box 10, a contact rod 20 is connected to one end of the control box 10, a contact sensor 21 is provided in the contact rod 20, a main board 30 is provided in the control box 10, the contact sensor 21 is electrically connected to the main board 30, an angle sensor 31 is also provided on the main board 30, the angle sensor 31 is electrically connected to the contact sensor 21 and the main board 30 respectively, the contact sensor 21 is used to detect the angle change of the contact rod 20, the main board 30 is also provided with a power supply 36 and a vibrator 32, the vibrator 32 is electrically connected to the contact sensor 21, and the vibrator 32 is used to vibrate after the contact sensor 21 detects the angle change of the contact rod 20;

[0031] Specifically, the control box 10 is worn on the user's wrist through a wristband 40, and is shaped like a watch. The contact rod 20 is located at one end of the control box 10. When the control box 10 is worn, the contact rod 20 is located at the back of the user's hand. When the hand posture meets the playing standard, the contact rod 20 will not contact the contact rod 20. If the hand posture is incorrect, the back of the hand will contact the contact rod 20, and the contact sensor 21 will be triggered. After the contact sensor 21 is triggered, it will send a trigger signal to the angle sensor 31 to detect the angle position of the contact rod 20 at this time. If it is detected that the angle position of the contact rod 20 has changed and is not within the preset value, the angle sensor 31 will send a signal to the main board 30. The main board 30 controls the vibrator 32 to work according to the electrical signal, and vibrates to remind the user that the hand posture is inaccurate at this time. Among them, the vibrator 32 uses a motor, and the contact rod 20 is in an arc shape, which is more convenient to fit the wrist.

[0032] Further, in this embodiment, a bearing hole is provided at the tail end of the contact rod 20, and an adjusting bearing 24 is provided at the end of the control box 10. The bearing hole cooperates with the adjusting bearing 24, and the contact rod 20 is rotatably connected to the control box 10 through the adjusting bearing 24. A pickup 22 is also provided in the contact rod 20.

[0033] Specifically, the connection between the contact rod 20 and the control box 10 is a rotational connection, so that when the contact rod 20 contacts the back of the user's hand, it will be lifted up by an irregular hand posture, thereby triggering the angle sensor 31, reminding the user to pay attention to the hand posture at all times, wherein the contact rod 20 and the control box 10 are rotationally connected through an adjusting bearing 24, the adjusting bearing 24 has a certain damping effect, and there will be a torsion spring inside it, through the torsion spring, the contact rod 20 will always be in an initial state without being affected by external forces, the damping effect is achieved by the torsion spring, and at the same time, the adjusting bearing 24 can adjust the initial angle of the contact rod 20 to adapt to wrists of different sizes; because forming a habit requires repetitive practice, in order to facilitate the user to clearly know the number of finger shifts to maintain the hand posture, a pickup 22 is also provided in the contact rod 20, the pickup 22 can pick up the sound emitted by the guzheng each time the fingers are shifted, and count, when a certain number of times is reached, the mainboard 30 will control the vibrator 32 to work, reminding the user that the number of postures has reached the standard.

[0034] It should be pointed out that the pickup 22 is a microphone, which can collect external sounds, and is arranged in the contact rod 20 because the contact rod 20 is closer to the sound source, which is more convenient for accurate pickup.

[0035] It should be pointed out that the contact rod 20 can also be fixed, that is, the contact rod 20 is not adjusted, and the effect of the present application can also be achieved.

[0036] Furthermore, in this embodiment, the main board 30 is further provided with function buttons 33, a digital tube display 34 and a speaker 35. The function buttons 33 are provided with a plurality of buttons for controlling the start and stop of related functions; the digital tube display 34 is used to display counts and duration; the speaker 35 is used for voice reminders; a charging port 37 is also provided on one side of the main board 30;

[0037] Specifically, in order to enable the user to know the number of single finger tapping of a certain hand posture at any time, a digital tube display 34 is also provided on the main board 30. The digital tube display 34 is used to display the number of counts and can also be used for timing. For example, after a preset time, it will remind the user. The speaker 35 is used to increase the reminder method of the monitor. Through the setting of the speaker 35, the monitor can not only vibrate to remind, but also give voice reminders, further improving the practicality. In order to get rid of the constraints of wires, a battery is provided in the control box 10. The battery can store electricity for use in supplying power to the main board 30 and various electrical appliances when needed. The charging port 37 of the main board 30 is used to charge the battery to realize the cyclic practicality of the monitor. The charging port 37 can be any one of MicroUSB, Type-C and Lightning interfaces. In this application, Type-C is preferred, which has a wider range of use and higher adaptability.
