Two supporting grooves 9 are provided on the inner wall of the circular groove 3. Two supporting blocks 10 are fixedly provided on the outer surface of the arc block 2. The two supporting blocks 10 extend to the inside of the two supporting grooves 9 respectively at one end away from the arc block 2. The outer surfaces of the two supporting blocks 10 are movably connected with the inner surfaces of the two supporting grooves 9. Spring components are respectively provided inside the two supporting grooves 9. The two ends of the spring components are respectively fixedly connected with the two supporting blocks 10 and the opposite side of the two supporting grooves 9. A power component is provided between the two trapezoidal blocks 5. The outer surface of the power component is movably connected with the opposite side of the two trapezoidal blocks 5. The power component extends out of the inside of the heel tensioner mold 1 away from the side of the arc block 2, and the outer surface of the power component is movably connected with the inner surface of the heel tensioner mold 1 The power assembly includes a driving column 11, which is movably arranged inside the circular groove 3, one side of the driving column 11 extends into the movable groove 4, the outer surface of the driving column 11 is movably connected to the opposite side of the two trapezoidal blocks 5, the driving column 11 extends out of the heel tensioner mold 1 away from the arc block 2, the outer surface of the driving column 11 is movably connected to the inner surface of the heel tensioner mold 1, both ends of the driving column 11 are respectively fixed with blocking members, two semicircular blocks 12 are respectively fixed at both ends of the inner surface of the circular groove 3, the outer surface of the driving column 11 and the outer surfaces of the two blocking members are respectively movably connected to the outer surfaces of the two semicircular blocks 12, and the blocking member includes a blocking block 13, one end of the blocking block 13 is fixedly connected to one end of the driving column 11, and the outer surfaces of the blocking block 13 are respectively connected to the outer surfaces of the two semicircular blocks 12 The inner surface of the circular groove 3 is movably connected, and a limiting ring 14 is fixedly provided on one side away from the two semicircular blocks 12. The outer surface of the driving column 11 is movably connected to the inner surface of the limiting ring 14. The two blocking blocks 13 are movably connected to one side of the limiting ring 14 away from the arc block 2. The spring assembly includes a second spring 15. The second spring 15 is arranged in one of the supporting grooves 9. The two ends of the second spring 15 are respectively fixedly connected to one of the supporting blocks 10 and the opposite side of one of the supporting grooves 9. The limiting ring 14 limits the driving column 11. At the same time, the blocking blocks 13 on both sides limit the driving column 11 through the movable groove 4, so that the driving column 11 can only perform linear motion in the circular groove 3. At the same time, the driving column 11 can be prevented from changing its angle in the circular groove 3.In this way, the driving column 11 is prevented from entering between the two trapezoidal blocks 5. When the staff uses the driving column 11 to drive the arc block 2 to extend, the circular groove 3 limits the two limit columns 6 to prevent the two limit columns 6 from extending. Therefore, when the driving column 11 contacts the two trapezoidal blocks 5 and enters between the two trapezoidal blocks 5, the support block 10 limits the arc block 2 through the support groove 9 to prevent the arc block 2 from escaping from the circular groove 3. By preventing the arc block 2 from rotating, the situation that the limit column 6 cannot enter the limit groove 7 normally is avoided. When the arc block 2 is extended, the driving column 1 1 drives the two blocking blocks 13 to enter between the two semicircular blocks 12 and the arc block 2. When the staff rotates the driving column 11, the two blocking blocks 13 fit with the outer surfaces of the two semicircular blocks 12. At the same time, the second spring 15 drives the driving column 11 through the arc block 2, so that the driving column 11 drives the two blocking blocks 13 to fit with the two semicircular blocks 12 more stably. This structure improves the stability of the arc block 2 when it is extended. When processing ordinary shoes, the force will be transmitted to the two blocking blocks 13 through the arc block 2 and the driving column 11, and the two blocking blocks 13 will be transmitted to the heel tightener mold 1 through the two semicircular blocks 12.
[0026] The working principle provided by the utility model is as follows: when it is necessary to process the BOA buckle shoes, the staff pulls and rotates the driving column 11 to make the driving column 11 leave the movable groove 4 of the arc block 2, and at the same time, the driving column 11 drives the two blocking blocks 13 to retract from the notch between the two semicircular blocks 12, thereby releasing the drive to the arc block 2 and the two trapezoidal blocks 5. According to the stretchability of the spring, the two first springs 8 stretch to drive the two trapezoidal blocks 5 to move relative to each other, and at the same time drive the two limiting columns 6 to leave the two limiting grooves 7. At the same time, the second spring 15 stretches to drive the arc block 2 to retract through the two support blocks 10. The staff can use the mold to process the BOA buckle shoes. When it is necessary to process the general When processing the ordinary shoes, the staff applies a thrust to the driving column 11, so that the driving column 11 drives the arc block 2 to extend through the two trapezoidal blocks 5. At the same time, the arc block 2 drives the two second springs 15 to be in a compressed state through the two support blocks 10. When the arc block 2 moves to the value of the two limit grooves 7, the driving column 11 will enter between the two trapezoidal blocks 5, drive the two trapezoidal blocks 5 to extend, and drive the two limit columns 6 to enter the two limit grooves 7 through the two trapezoidal blocks 5. At the same time, the staff rotates the driving column 11, so that the driving column 11 drives the two blocking blocks 13 to rotate, so that the two blocking blocks 13 are fitted with the two semicircular blocks 12, completing the limiting of the arc block 2. The staff can use the mold to process ordinary shoes.
