The quick-lock screw 14 locks the screw 13 by abutting against the outer wall of the screw 13 to keep it fixed to the rectangular frame 4, avoiding continued rotation and causing the adjusted position of the movable plate 5 to change. When adjusting again, just loosen the quick-lock screw 14;

[0028] like Figure 1 、 Figure 3 and Figure 4As shown, in order to facilitate the rotation of the screw 13 to adjust the position of the movable plate 5, the end of the screw 13 away from the movable plate 5 is fixedly connected to the first rotating rod 9, and the adjustment box 8 is fixedly connected between the two sets of oblique rods 3 and located at the rear side of the connecting seat 12. The inner rear wall of the adjustment box 8 is rotatably connected to the first bevel gear 17. The end of the first rotating rod 9 away from the screw 13 sequentially penetrates the front wall of the adjustment box 8, the inner wall of the first bevel gear 17 and the rear wall of the adjustment box 8 and extends to the rear side of the adjustment box 8. The inner lower wall of the adjustment box 8 and the upper wall of the adjustment box 8 and are located on the right side of the first rotating rod 9 and rotate A second rotating rod 16 is connected, and the outer wall of the second rotating rod 16 is fixedly connected to a transmission structure for meshing with the first bevel gear 17 for transmission. The end of the second rotating rod 16 away from the inner lower wall of the adjustment box 8 passes through the upper wall of the adjustment box 8 and extends above the adjustment box 8. The end of the second rotating rod 16 extending above the adjustment box 8 is fixedly connected to a rotating handle 11 for facilitating the rotation of the second rotating rod 16. The upper wall of the adjustment box 8 is fixedly connected to a rotating seat 10, and the second rotating rod 16 is rotatably connected to the inner wall of the rotating seat 10.

After loosening the quick-lock screw 14, the rotating handle 11 is rotated to drive the second rotating rod 16 to rotate through the rotating handle 11, and then the first bevel gear 17 is driven to rotate through the second bevel gear 18. The first bevel gear 17 drives the first rotating rod 9 to rotate through the spline teeth 15 and the spline grooves 19. Since the first rotating rod 9 is fixedly connected to the screw rod 13, the rotation operation of the screw rod 13 is realized. The first rotating rod 9 and the first bevel gear 17 are both slidably connected and rotatably connected to facilitate the axial movement of the screw rod 13 after rotation.

[0029] Working principle: An F-type wrench is formed by two sets of cross bars 2 and a straight bar 1, which can be used to open butterfly valves and stop valves. The two sets of cross bars 2 can also be set to a movable form consistent with the existing F-type wrenches with adjustable openings on the market to accommodate butterfly valves and stop valves of different sizes. The movable plate 5 is slidably connected to the rectangular frame 4 through the first guide rod 6 and the second guide rod 7. When the movable plate 5 moves back and forth, it is guided by the first guide rod 6 and the second guide rod 7 to avoid scratching or collision between the side wall of the movable plate 5 and the inner left wall of the rectangular frame 4 or the inner right wall of the rectangular frame 4. Through the threaded connection relationship between the screw 13 and the connecting seat 12, the screw 13 can move back and forth along its axial direction when it rotates, thereby driving the movable plate 5 to move back and forth, thereby adjusting the distance between the front wall of the movable plate 5 and the inner front wall of the rectangular frame 4. When applied to ball valve operation, it can be achieved for different models of ball valves. The purpose of adjusting the wrench is to lock the screw 13 and the rectangular frame 4 through the quick-lock screw 14. The quick-lock screw 14 locks the screw 13 by abutting against the outer wall of the screw 13 to keep it fixed to the rectangular frame 4, to prevent continued rotation from causing the adjusted position of the movable plate 5 to change. When adjusting again, loosen the quick-lock screw 14. After loosening the quick-lock screw 14, turn the rotating handle 11, and the second rotating rod 16 can be driven to rotate by the rotating handle 11, and then the first bevel gear 17 can be driven to rotate by the second bevel gear 18. The first bevel gear 17 drives the first rotating rod 9 to rotate through the spline teeth 15 and the spline groove 19. Since the first rotating rod 9 is fixedly connected to the screw 13, the rotation operation of the screw 13 is realized. The first rotating rod 9 and the first bevel gear 17 are both slidably connected and rotatably connected to facilitate the axial movement of the screw 13 after rotation.
