The outer side of the golf club is coated with the DLC coating, so that the golf club has good abrasion resistance and lubricity and has electrical insulation, and the service life of the golf club is prolonged.

The invention discloses a man-machine interaction system and a man-machine interaction method for training the phoneme distinguishing capability of developmental reading disorder. The man-machine interaction system comprises an evaluation unit which is used for collecting personal information of a user and evaluation results of voice consciousness; the parameter configuration unit is connected with the evaluation unit, is provided with a preset element library and a preset rule library, and is used for configuring a practice interaction task and a formal interaction task with preset difficulty for the user based on the evaluation result; the exercise task unit and the formal task unit are both connected with the parameter configuration unit so as to perform man-machine interaction with a user according to the sequence of first exercise and then formal; the learning unit is connected with the formal task unit so as to perform learning reinforcement when the user answers an error and perform formal interaction again after learning is completed; and the feedback unit is connected with the formal task unit and is used for feeding back the interaction result to the user. According to the invention, learning and practice are combined, so that the knowledge boundary of children is expanded, and the confidence and learning ability of children are improved.

The invention relates to a network teaching system and a network teaching method thereof. The network teaching system comprises a teacher terminal used for uploading a calligraphy teaching video and a standard copybook; the student terminal comprises a touch screen and a camera, the touch screen is used for writing input, and the camera is used for capturing the writing process in real time; the stroke sequence recognition module accurately detects errors in the writing process by comparing the writing sequence of the students with the stroke sequence of the standard copybook, when the stroke sequence errors are detected, the system prompts the students to adjust the writing sequence through immediate feedback, and the pressure induction feedback module detects pressure changes of the students during writing through the touch screen. The handwriting thickness is analyzed through an algorithm, whether the writing strength accords with the preset reasonable range or not is judged, and when the writing strength deviation of a student is too large, the system reminds the student to adjust the strength through a visual or sound signal so as to ensure the handwriting quality of writing.

The utility model relates to a three-split metal bow handle which comprises a handle, mounting tables are integrally formed at the top and the bottom of the handle, an L-shaped mounting groove is integrally formed in one side of each mounting table, a connecting bolt is arranged in the middle of each mounting groove, and a supporting table is integrally formed at the end, away from the center of the handle, of each mounting table. A limiting frame is arranged on one side of the supporting table, the center of the interior of the limiting frame is fixedly connected with a limiting groove plate through a fixing pin, and a plurality of connecting holes penetrating to the back face are formed in the front face of the handle. According to the utility model, most types of bow pieces can be inserted on the mounting table and are fixed with the handle through the connecting bolts, so that the handle can be suitable for more than 95% of bow pieces on the market, and after the bow pieces are replaced, the bow handle is not changed, so that the hand feeling can be still kept during training, the use is very convenient, the exercise cost is reduced, and the exercise efficiency is improved. And the exercise efficiency is effectively improved.

This design belongs to the technical field of input method practice software, specifically involving a nine-key input method practice software that is compatible with various nine-key input methods, supports key-specific practice, and provides real-time feedback on correct and incorrect input.

The invention discloses a golf putter trainer, and belongs to the technical field of auxiliary training equipment for golf sports. The device mainly comprises a main body frame, a ball box assembly, a push rod blanket, a ball return rail assembly and a gradient adjusting mechanism. The main body frame comprises a side wall baffle and a bottom supporting rod, the front ends of which are rotationally connected; the ball box assembly comprises a push rod panel and a reinforcing plate connected with the baffles on the two sides. According to the golf putter trainer, the height of the rear end of the putter panel is changed through the gradient adjusting mechanism, so that the putter panel rotates around the pivot shaft at the front end, and the inclination angle is flexibly adjusted to simulate putting green with different gradients; and meanwhile, the falling balls are guided to the ball return rail assembly by matching with ball guide structures on the side surfaces of the side wall baffles to realize automatic recovery. The device is stable in structure and smooth in adjustment, and the reality sense and convenience of push rod training are effectively improved.

The invention relates to the technical field of auxiliary equipment, and discloses an auxiliary device for calligraphy practice, which comprises a table plate which is used as a basic component of the whole device and is used for assembling and bearing each processing mechanism and a subordinate lower structural component; the correction assisting mechanism is arranged on the front side of the table board and used for conducting auxiliary correction treatment on the body posture of the practicer in the calligraphy practicing process; and the light and shadow guide mechanism is arranged at the top of the table board. By adding and arranging the light and shadow guide mechanism, a calligraphy sample is clearly projected on paper by means of an ingenious light and shadow projection mode when calligraphy is practiced, so that a practicer can intuitively compare own works with a copy book and accurately perceive the difference between the works and the copy book, the stroke form, the structural layout and the overall romantic charm are not needed, and the calligraphy effect is improved. And on the basis of the clear reference, a practicer can timely correct defects in the practice process and continuously perfect writing, so that the efficiency and the quality of calligraphy practice are effectively improved.
