[0019] Further, two groups of first hinge blocks 6 are symmetrically fixedly installed on the inner front side of the fixed seat 4, and the first hinge rods 7 are hingedly installed on the two groups of first hinge blocks 6. Two groups of second hinge blocks 8 are symmetrically slidably installed on the inner rear side of the fixed seat 4, and the second hinge rods 9 are hingedly installed on the two groups of second hinge blocks 8. Two groups of first hinge blocks 6 are symmetrically fixedly installed on the front end of the lower side of the fixed plate 5, and two groups of second hinge blocks 8 are symmetrically slidably installed on the rear end of the lower side of the fixed plate 5. The upper ends of the two groups of first hinge rods 7 are hinged to the two groups of second hinge blocks 8 on the upper side, and the upper ends of the two groups of second hinge rods 9 are hinged to the two groups of first hinge blocks 6 on the upper side. The first hinge rod 7 is hinged to the middle part of the second hinge rod 9, as shown in FIG. Figure 4 As shown, this arrangement facilitates the subsequent lifting of the fixed plate 5.

[0020] Furthermore, a connecting rod 11 is fixedly installed on the opposite side of the lower end of the two sets of first hinged rods 7 and second hinged rods 9. Figure 4 As shown, through this arrangement, two groups of first hinged rods 7 can be controlled to rotate simultaneously.

[0021] Furthermore, the locking assembly includes a gear 10, a pull rod 12, a limit block 13 and a spring 14. The gear 10 is fixedly installed at the lower end of the first hinged rod 7, and the pull rod 12 is movably inserted inside the right end of the fixed seat 4. The limit block 13 is fixedly installed at the rear end of the pull rod 12. The rear end of the limit block 13 is inclined, and the rear end of the limit block 13 is meshed with the teeth of the gear 10. The spring 14 is slidably installed on the pull rod 12. Figure 4 Through this setting, the position of the fixing plate 5 can be limited and fixed.

[0022] Furthermore, a collecting bin 15 is movably inserted inside the fixing seat 4. Figure 3 As shown, the fragments after punching can be collected through this arrangement.

[0023] Furthermore, the clamping assembly includes a bidirectional screw 16 and a clamping plate 17. The rear end of the fixed seat 4 is rotatably mounted with the bidirectional screw 16. The left and right threads of the bidirectional screw 16 are mounted with the clamping plates 17. The upper side of the fixed plate 5 is symmetrically provided with two groups of limit grooves 18. The front ends of the two groups of clamping plates 17 slide inside the limit grooves 18. The right end of the bidirectional screw 16 is fixedly mounted with a turning handle 19. Figure 3 As shown, molds of different sizes can be clamped and fixed by the clamping assembly.

[0024] Working principle: When the device is used, the staff pulls out the fixed seat 4 from the upper side of the slide 3, and then the staff places the mold to be punched on the upper side of the fixed plate 5. Then the staff grasps the turning handle 19 and turns it clockwise, and the turning handle 19 drives the bidirectional screw 16 to rotate clockwise. The two sets of clamping plates 17 are close to each other under the action of the thread, and then the left and right ends of the mold are clamped and fixed. Then the staff pushes the fixed seat 4 and starts the hand-pressed punching machine body 2 to punch the mold on the fixed plate 5. The punched fragments fall into the collection bin 15. After the punching is completed, the staff pulls the fixed seat 4 outward and pulls out the processed mold. Then the fixed plate 5 can be pulled upward, and the fixed plate 5 drives the two sets of first hinged rods 7 and second hinged rods 9 to move simultaneously. When the gear 10 rotates, it rotates and drives the gear 10 fixedly installed at the lower end of the first hinge rod 7 to rotate. Since the limit block 13 is inclined, when the gear 10 rotates clockwise, it will control the limit block 13 to move backward. When it moves to the next set of teeth, the limit block 13 is ejected backward by the elastic force of the spring 14, and then the rear end of the limit block 13 is inserted between the two sets of teeth. Through this arrangement, the position of the fixed plate 5 can be raised and lowered, so that the staff can better observe the punching situation and it is convenient to take out the punched mold. After use, the staff pulls the pull rod 12 outward and drives the limit block 13 to move forward, and then presses the fixed plate 5 downward to reset the fixed plate 5. The above is the entire working principle of the utility model.
