The rotation of the threaded rod 11 is controlled by the handle 14, and threadedly transmitted with the mounting sleeve 3, so that the bottom end of the threaded rod 11 squeezes the compression spring 8, which is convenient for applying pressure to the movable block 7. The charged elasticity of the compression spring 8 is utilized to adapt to the vibration caused during the bending process, thereby ensuring the stability of the fit between the ball 13 and the limit groove 5.

[0027] The bottom surface of the movable block 7 and the inner surface of the limiting groove 5 are both trapezoidal in structure. The movable block 7 can squeeze the ball 13 on the bottom surface when it moves vertically downward. The ball 13 rolls inside the slide groove 12.

[0031] Working principle: first, make the limit grooves 5 of the upper mold 1 and the lower mold 2 correspond to each other and fit each other, then insert the installation sleeve 3 into the limit groove 5, when the positioning bushing 4 fits with the top surface of the upper mold 1, the positions of the slide groove 12 and the limit groove 5 also correspond to each other, and the ball 13 is squeezed under the deadweight of the movable block 7, and the ball 13 slides from the slide groove 12, and the outer surface of one end of the ball 13 fits with the inner surface of the limit groove 5, thereby forming a vertical limit for the upper mold 1 and the lower mold 2, and then control the handle 14 to rotate the threaded rod 11, the threaded rod 11 and the installation sleeve 3 are threaded and move vertically downward, which can squeeze the compression spring 8, thereby ensuring the tightness of the movable block 7, which is not only convenient to install, but also has a shock-absorbing effect, avoids accidental unlocking, and will not cause overload or jamming, thereby increasing the stability of the clamping mold processing.
