[0048] Example 1:

[0049] See also Figures 1 to 5The utility model relates to an automatic adjustment type violin playing right hand bow technique correction training device, comprising a violin bow rod 1, a finger corrector 2 which is snapped into the outer side of the violin bow rod 1, a bottom plate 3 which is slidably connected to the lower end surface of the finger corrector 2, a wrist bracket 4 which is fixedly connected to the upper end surface of the bottom plate 3 away from the finger corrector 2, a strap 5 being fixedly connected to the upper end of the wrist bracket 4, a king-shaped slide groove 6 being provided on the upper end surface of the bottom plate 3, a screw rod 7 which is threadedly inserted into the lower end surface of the finger corrector 2, and the screw rod 7 passes through the king-shaped slide groove. The groove 6 is slidably connected to the inner groove of the Wang-shaped slide 6, and the lower end surface of the screw 7 is fixedly connected to the knob 8. The upper end of the finger corrector 2 is provided with a groove 9, and three partitions 10 are fixedly connected to the inner side of the groove 9. The left and right sides of the partition 10 are provided with a first small slide 11. The rear end surface of the finger corrector 2 is provided with two second small slides 12. The bottom of the rear end surface of the finger corrector 2 is provided with a bayonet 13. The inner groove 9 is provided with an inner groove 14, and the second small slide 12 and the inner groove 14 are connected to each other. The inner side of the groove 9 is slidably connected with the first set The first sleeve 15 is slidably connected to the inner side of the groove 9, and the first sleeve 15 and the second sleeve 16 are set as a group, and there are two groups in total. The first sleeve 15 and the second sleeve 16 are symmetrically arranged with each other. The upper end of the second sleeve 16 is fixedly connected to a rubber rope 160, and the outer side of the second sleeve 16 is fixedly connected to two rubber pads 161. A small fixing column 162 is rotatably connected between the two rubber pads 161 on the outer side of the second sleeve 16. The small fixing column 162 is fixedly connected away from one end of the second sleeve 16. A bolt 163 is connected, and a slider 17 is slidably connected to the inside of the inner groove 14. A worm gear 18 is rotatably connected inside the slider 17. Straight bolt sleeves 19 are fixedly connected to the centers of the left and right sides of the worm gear 18, and the bolt 163 is inserted into the inner side of the straight bolt sleeve 19 and is threadedly connected to the straight bolt sleeve 19. The straight bolt sleeve 19 passes through the first small slide groove 11 and is slidably connected to the first small slide groove 11. The upper end of the worm gear 18 is meshed with a worm 20, and the front end surface of the worm 20 is fixedly connected to a small knob 21 through a connecting column.

[0050] The working principle of an automatic adjustment type violin playing right hand bowing correction trainer based on embodiment 1 is as follows:

[0051] First, before use, insert the outer side of the violin bow 1 into the inner side of the rear end slot 13 of the finger corrector 2 to limit and fix it;

[0052] Second, place the wrist on the wrist support 4 and secure it with the strap 5. Then insert four fingers into the first sleeve 15 and the second sleeve 16. Adjust the fingers so that the front ends of the fingers touch the outer side of the violin bow 1. During the adjustment, since the fingers are inside the first sleeve 15 and the second sleeve 16, the fingers will also drive the first sleeve 15 and the second sleeve 16 to move (or rotate) when they move and bend, driving the small fixing column 162 to be inserted into the inner side of the straight bolt sleeve 19 through the bolt 163, and driving the slider 17 to slide inside the inner groove 14.

[0053] Third, when the fingers are bent, the first sleeve 15 and the second sleeve 16 drive the finger corrector 2 to move, and at the same time, the screw 7 slides inside the Wang-shaped slide groove 6. Then, the screw 7 is driven upward by turning the knob 8, and at the same time, the knob 8 is driven to press against the lower end surface of the base plate 3 to fix the finger corrector 2 to the base plate 3 (the finger corrector 2 and the base plate 3 are in a non-fixed state by default), so as to achieve the best hand posture adjustment, and then the thumb drags the lower end of the violin bow 1;

[0054] Fourth, turn the small knob 21 to drive the worm 20 to rotate through the worm gear 18, so that the straight bolt sleeve 19 and the bolt 163 are threaded and tightened, and the bolt 163 is driven to move toward the side of the straight bolt sleeve 19. The bolt 163 moves through the small fixing column 162 to pull the second sleeve 16 to move, so that its rubber pad 161 contacts the left (or right) side of the partition 10, and the second sleeve 16 is relatively fixed on the inner side of the groove 9 through friction force, so that the finger posture is relatively shaped, and then the use training can be carried out.

[0055] The present invention provides an automatic adjustment type violin playing right-hand bowing correction and training device through improvement. When using it, first insert the fingers into the inner sides of the first sleeve 15 and the second sleeve 16, and hold the base plate 3 with the other hand. The first sleeve 15 and the second sleeve 16 are driven by the fingers to move and adjust the finger corrector 2 on the base plate 3. After completion, the knob 8 is turned to fix it. Then, the wrist is tied and fixed by the strap 5. After the fingers adjust the bow holding posture, the first sleeve 15 and the second sleeve 16 are fixed by turning the small knob 21 to fix the finger posture. The thumb is placed on the lower end of the violin bow rod 1 to start use training.
