[0041] Among them, through the setting of the guide groove 511 and the guide slide column 611, when the turntable 420 rotates forward and backward in the rotating chamber 401, the side wall of the guide groove 511 squeezes the corresponding guide slide column 611, which can drive the clamping joint 320 to move back and forth along the corresponding groove 311, thereby better realizing the three clamping joints 320 approaching or moving away from each other, that is, realizing the disassembly and assembly of the punch head 132 on the movable mold base 131.

[0042] In this embodiment, a notch 301 is provided on the side surface of the mounting disc 300 along its circumference, a lever 421 extending out of the notch 301 is provided on the side wall of the rotating disc 420 , and a fixing piece for fixing the rotating disc 420 is provided at the extending end of the lever 421 .

[0043] Through the structure of this embodiment, in actual use, the rotating disk 420 can be driven to rotate in the rotating chamber 401 by moving the lever 421 extending out of the slot 301, which makes the rotating operation of the rotating disk 420 relatively simple.

[0044] Among them, by setting the fixing part, in actual use, the fixing part can fix the lever 421, so that the turntable 420 is fixed, and then the card joint 320 is better kept in a state of extending into the corresponding card groove or keeping the card joint 320 in a state of being away from each other, so as to avoid the lever 421 from accidentally sliding in the slot 301 and causing the turntable 420 to accidentally rotate, affecting the actual use of the quick release assembly 200.

[0045] Combination Figure 3-5 As shown, in this embodiment, the fixing member includes a sleeve 520 which is sleeved on the outside of the protruding end of the lever 421, and an arc-shaped plate 521 is provided on the end of the sleeve 520 facing the mounting disc 300, and a positioning column 522 is relatively provided on the side surface of the arc-shaped plate 521 facing the mounting disc 300, and positioning holes 302 for corresponding positioning columns 522 to extend into are provided at the outer side surface of the mounting disc 300 and at both ends of the slot 301, and a mounting ring 530 is provided at the protruding end of the lever 421, and a spring 540 for driving the arc-shaped plate 521 to move toward the outer side surface of the mounting disc 300 is sleeved on the lever 421 located between the sleeve 520 and the mounting ring 530.

[0046] In actual use of this embodiment, the mounting ring 530 is threadedly mounted on the protruding end of the lever 421, thereby preferably achieving the installation of the spring 540 and the sleeve 520 on the lever 421;

[0047] The lever 421 is provided with a limit groove (not shown in the figure) along its length direction, and the sleeve 520 is provided with a limit block (not shown in the figure) extending into the limit groove, thereby preferably realizing the keyway cooperation between the sleeve 520 and the lever 421, that is, the sleeve 520 will not rotate around the lever 421, affecting the subsequent use of the lever;

[0048] The spring 540, the arc plate 521, the positioning column 522 and the positioning hole 302 are arranged so that the spring 540 always pushes the sleeve 520 to move the arc plate 521 toward the mounting disc 300, thereby driving the positioning column 522 to extend into the corresponding positioning hole 302, so that the lever 421 is fixed, that is, the rotating disk 420 is fixed to prevent it from rotating by mistake. By pulling the arc plate 521 to move along the lever 421, the positioning column 522 is separated from the corresponding positioning hole 302. At this time, the lever 421 can be released from being fixed, so that it can slide along the notch 301 to drive the rotating disk 420 to rotate.

[0049] Among them, in order to better facilitate the operator to pull the arc plate 521 to move, a U-shaped handle 523 covering the outside of the lever 421 is provided on the arc plate 521. By pulling the U-shaped handle 523, the arc plate 521 can be driven to move, which is more convenient to release the fixation of the lever 421 by the fixing part. At the same time, pushing the U-shaped handle 523 can drive the lever 421 to slide along the slot 301 to rotate the turntable 420, thereby facilitating the rotation of the turntable 420, making the use of the fixing part more convenient.

[0050] Working principle: the aluminum sheet to be punched is placed on the fixed die 120, and the cylinder 111 is started to drive the movable die 130 to rise and fall, so that the punch head 132 extends into the concave die cavity 211, and the punching operation of the aluminum sheet can be completed; when the punch head 132 needs to be replaced, the arc plate 521 can be driven to move by pulling the U-shaped handle 523, so that the positioning column 522 is separated from one positioning hole 302, and the U-shaped handle 523 is pushed to drive the lever 421 to rotate the turntable 420 to another positioning hole 302, at this time, the U-shaped handle 523 is released to extend the positioning column 522. The punch head 132 can be replaced by inserting it into another positioning hole 302. The mounting column 430 on the replaced punch head 132 is abutted against the lower side of the cover plate 310. The U-shaped handle 523 is then pulled to drive the arc plate 521 to move, so that the positioning column 522 is disengaged from the other positioning hole 302. The U-shaped handle 523 is pushed to drive the lever 421 to rotate the turntable 420 to a positioning hole 302. The U-shaped handle 523 is released to allow the positioning column 522 to extend into a positioning hole 302, thereby completing the fixation of the replaced punch head 132.

[0051] In short, the above is only a preferred embodiment of the present utility model, and all equivalent changes and modifications made according to the scope of the patent application of the present utility model should fall within the scope of the present utility model patent.
