Because the middle part of the outer wall of the sliding rod 4 is fixedly connected with the connecting rod 6, the limit shaft rod 7 is fixedly connected to the middle part of the connecting rod 6, and the two ends of the limit shaft rod 7 are restricted to slide inside the oblique groove opened in the middle part of the two fixed plates 8, so when the sliding rod 4 rotates in the two elliptical tracks 5, it can drive the connecting rod 6 to circulate left and right at a uniform speed. Reciprocating motion, after the saw blade 12 is clamped, the adjusting bolt 11 threadedly connected to one side of the inclined sleeve 9 can be adjusted to lower or raise the push rod 10 so that the bottom of the push rod 10 engages with the teeth of the saw blade 12. When operating to the right, the push rod 10 sliding inside the inclined sleeve 9 is raised and moves to the right. When moving to the left, the push rod 10 drops and operates to the left. Because the bottom of the push rod 10 is an inclined cone, it pushes the teeth on the saw blade 12 to move toward the grinding wheel 22, thereby achieving a high-precision grinding effect.

[0026] Place the saw blade 12 between the two clamps 16. At this time, since multiple pairs of pins 14 are slidably connected on both sides of the mounting plate 13, a limit spring 15 is set on the outer wall of each pin 14, and the limit springs 15 are all set on the mounting plate 13, so under the restriction of the limit spring 15 and the inner side of the mounting plate 13, the two clamps 16 clamp the saw blade 12, making subsequent grinding easier.

[0027] refer to Figure 4A fixed column 17 is fixedly connected above the workbench 1, and first rotating rods 18 are rotatably connected to the two corresponding sides of the outer wall of the fixed column 17, and electric telescopic rods 20 are fixedly connected to the outer walls of the two first rotating rods 18. One end of the two electric telescopic rods 20 is fixedly connected to the second rotating rods 19, and a driving chassis 21 is arranged between the two second rotating rods 19. The two second rotating rods 19 are rotatably connected to the corresponding two sides of the outer wall of the driving chassis 21, and a grinding wheel 22 is fixedly connected to the output end of the driving chassis 21. An electric push rod 23 is fixedly connected to the bottom of the inner wall of the fixed column 17, and a support arm 24 is fixedly connected to the outer wall of the output end of the electric push rod 23. A groove matching the support arm 24 is provided on one side of the outer wall of the fixed column 17, and a connecting seat 25 is fixedly connected to the bottom of one end of the support arm 24. A convex plate 26 is rotatably connected to the inner side of the connecting seat 25, and the bottom of the convex plate 26 is fixedly connected to the top of the driving chassis 21.

[0028] When the two electric telescopic rods 20 arranged on both sides of the fixed column 17 are extended and retracted at the same time, because the first rotating rod 18 and the second rotating rod 19 are fixedly connected to the two ends of the electric telescopic rod 20, and the two first rotating rods 18 are rotatably connected to the fixed column 17, and the two second rotating rods 19 are rotatably connected to the two sides of the outer wall of the driving chassis 21, the driving chassis 21 can be operated left and right, and because the convex plate arranged on the top of the driving chassis 21 is rotatably connected to the limit of the connecting seat 25 at the bottom of the support arm 24, the driving chassis 21 can be tilted at a specified angle. At the same time, the output end of the electric push rod 23 connected to the bottom of the inner wall of the fixed column 17 is fixedly connected to one end of the support arm 24, so that the support arm 24 can be operated up and down with the groove opened on one side of the outer wall of the fixed column 17 as a track, indirectly making the driving chassis 21 operate up and down, and the grinding wheel 22 connected to the output end of the driving chassis 21 moves up and down accordingly and can be tilted at a specified angle, so as to realize the grinding of tooth grooves of different angles of different saw blades.

[0029] Working principle: First, place the saw blade 12 between the two clamping plates 16. At this time, because multiple pairs of pins 14 are slidably connected to both sides of the mounting plate 13, one end of each pin 14 is fixedly connected to one side of the clamping plate 16, and the limit spring 15 is arranged on the outer wall of each pin 14, and the limit spring 15 is arranged on the mounting plate 13. Therefore, under the restriction of the limit spring 15 and the inner side of the mounting plate 13, the two clamping plates 16 clamp the saw blade 12. After clamping, the adjusting bolt 11 threadedly connected to one side of the inclined sleeve 9 can be adjusted to make the push rod 10 descend or rise so that the bottom of the push rod 10 is engaged with the teeth of the saw blade 12. At this time, The two electric telescopic rods 20 arranged on both sides of the control fixed column 17 are extended or retracted at the same time. Since the first rotating rod 18 and the second rotating rod 19 are fixedly connected to both ends of the electric telescopic rod 20, and the two first rotating rods 18 are rotatably connected to the fixed column 17, and the two second rotating rods 19 are rotatably connected to both sides of the outer wall of the driving chassis 21, the driving chassis 21 can be operated left and right. In addition, due to the restriction that the convex plate arranged on the top of the driving chassis 21 is rotatably connected to the connection seat 25 at the bottom of the support arm 24, the grinding wheel 22 connected to the output end of the driving chassis 21 can be tilted to an angle suitable for the teeth of the saw blade 12, and then The output end of the driving motor 2 fixed on the top of the workbench 1 can drive the two elliptical plates 3 to rotate, so that the sliding rod 4 slides inside the elliptical track 5 opened on the corresponding sides of the two elliptical plates 3. Because the middle part of the outer wall of the sliding rod 4 is fixedly connected with a connecting rod 6, the limiting shaft rod 7 is fixedly connected to the middle part of the connecting rod 6, and the two ends of the limiting shaft rod 7 are restricted to slide inside the oblique groove opened in the middle part of the two fixed plates 8. Therefore, when the sliding rod 4 rotates in the two elliptical tracks 5, it can drive the connecting rod 6 to perform a left and right circular reciprocating motion at a uniform speed. When moving to the left, the push rod 10 drops down and operates to the left. Because the bottom of the push rod 10 is an oblique cone, the push rod 10 The teeth on the moving saw blade 12 move toward the grinding wheel 22. At the same time, the output end of the electric push rod 23 connected to the bottom of the inner wall of the fixed column 17 is fixedly connected to one end of the support arm 24, so that the support arm 24 can move downward with the groove opened on one side of the outer wall of the fixed column 17 as a track, and indirectly make the grinding wheel 22 move downward, and the driving chassis drives the grinding wheel 22 to rotate and grind the saw blade 12. Then, the electric push rod 23 rises and drives the chassis 21 to rise, and the connecting rod 6 moves to the right, so that the top rod 10 is raised and moves to the right. Then the connecting rod 6 moves to the left and the top rod 10 drops and operates to the left, and the movement is cyclical.
