[0045] Further, such as Figure 7 , 10 As shown in 11, the fixing assembly 9 includes a slot 91, a threaded hole 92, a fixing hole 93 and a fixing bolt 94. The slot 91 is provided at the bottom of the mounting base 3. The side surface of the mounting base 3 is linearly arranged from front to back with threaded holes 92 passing through the slot 91. The upper end of the saw blade 4 is plugged into the slot 91 up and down correspondingly. The side surface of the saw blade 4 is linearly arranged from front to back with fixing holes 93 corresponding to the threaded hole 92. The threaded hole 92 is internally threadedly connected with a fixing bolt 94 whose tail end passes through the fixing hole 93.

By screwing the clamping plate 73, the screw 72 is driven to rotate in the threaded hole 71, so that the bottom of the clamping plate 73 and the upper surface of the mounting seat 3 are respectively squeezed and clamped up and down with the upper surface and bottom of the mounting plate 1, and the clamping and fixing operation can be performed after the adjustment is completed (correspondingly, before the next adjustment, the reverse operation is performed to loosen the clamping plate 73 so that the clamping plate 73, the mounting seat 3 and the mounting plate 1 are separated and not in contact, and the moving and adjusting operation can be performed again).

[0047] Further, such as Figure 3 , 6As shown in Figure 9, the scale adjustment device 8 includes a slide groove 81, a scale 82, a measuring column 83, a pointer 84, a T-shaped slider 85 and a T-shaped slide groove 86. The slide grooves 81 are symmetrically provided at the front and rear ends of the upper surface of the mounting plate 1. The scales 82 are respectively provided at the positions on the upper surface of the mounting plate 1 on both sides of the two slide grooves 81. The front and rear ends of the upper surface of the mounting seat 3 are respectively provided with T-shaped slide grooves 86.

The principle is an existing mature technology and will not be described in detail here.

[0050] Further, such as Figure 2 As shown, arc-shaped finger grooves 13 corresponding to the fingers are arranged linearly from front to back at the bottom of the handle 2, and the arc-shaped finger grooves 13 facilitate the fingers to hold the saw better and more stably.

[0051] Furthermore, a connecting block 14 with arcs on the left and right sides is fixedly installed on the upper middle part of the front side of the mounting plate 1. The front end of the connecting block 14 is fixedly connected to the rear side of the handle 2 above the infrared positioning lamp 10. The connecting block 14 facilitates the stable connection and fixation of the handle 2 without affecting the measurement and use of the front auxiliary scale 87.

[0052] Further, such as Figure 8 As shown, the outer side of the clamping disk 73 is provided with anti-skid grooves 15 , which play an auxiliary anti-skid role when the clamping disk 73 is twisted.

[0053] When using:

[0054] The corresponding saw blades 4 are fixedly mounted on the seven mounting seats 3 respectively by the fixing assembly 9. Specifically, the saw blade 4 is installed by inserting the upper end of the saw blade 4 into the slot 91, tightening the threaded hole 92 of the fixing bolt 94 and passing it through the fixing hole 93 for fixing;

[0055] Through the scale adjustment device 8, the positions of the seven mounting seats 3 and the saw blades 4 thereon can be accurately adjusted according to the needs of use, and they can be clamped and fixed through the clamping and fixing assembly 7. Specifically, by moving the adjusting column 6, it is made to slide or rotate in the adjusting groove 5, and then the measuring column 83 is driven to move in the slide groove 81 and the T-shaped slide block 85 is driven to move in the T-shaped slide groove 86. Through the cooperation of the scale 82, the pointer 84, the auxiliary scale 87 and the indicator line 88, the positions of the front and rear ends of the mounting seat 3 and the saw blade 4 can be accurately measured and adjusted as needed. After the adjustment is completed, by twisting the clamping plate 73, the screw 72 is driven to rotate in the threaded hole 71, so that the bottom of the clamping plate 73 and the upper surface of the mounting seat 3 are respectively squeezed and clamped with the upper surface and the bottom of the mounting plate 1 up and down, and the clamping and fixing are completed.

[0056] The tuning machine is held by the handle 2, and the infrared positioning lamp 10 is started by the infrared lamp switch 11, and the center line is positioned at the Longyin position of the guqin (the center line of the Longyin position is drawn in advance with a pen and a ruler), so that the saw blade 4 located at the center position is aligned with the center line position; then, the tuning machine is pulled back and forth by holding the handle 2, and seven string-bearing grooves used for fixing and limiting the strings are synchronously sawed out by the seven saw blades 4, thereby completing the tuning and grooving operation.

[0057] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
