The sliding block 302 is slidably connected to the inside of the mounting plate 3;

[0027] As Figures 1-5 shown, a through hole is opened at the center of the pressing plate 7 for pressing. A through plate 701 is provided on one side of the pressing plate 7 close to the mounting plate 3. Pressing push rods 702 are fixedly connected to the center and both ends of the through plate 701. And an extrusion head corresponding to the through hole is provided at the inner extending end of the pressing push rod 702 at the center of the through plate 701. The pressing push rods 702 at both ends of the through plate 701 are fixedly connected to the sliding block 302. A sliding groove 303 corresponding to the sliding of the sliding block 302 is opened inside the mounting plate 3. The inner extending end of the pressing push rod 702 is fixedly connected to the pressing plate 7, so that the sliding block 302 drives the pressing plate 7 to adjust the angle through the pressing push rod 702. At the same time, the threaded rod 301 can also be rotated, thereby driving the sliding block 302 to move inside the sliding groove 303, so that the pressing push rod 702 is driven to displace, realizing the adjustment of the position of the pressing plate 7, and can effectively adapt to the punching operation of workpieces at different inclination angles and positions.

[0028] As Figure 2 、 Figure 5 shown, the support plate 2 is fixedly connected to the bottom plate 1, and a plurality of inclined blocks 201 are provided on one side of the support plate 2 close to the mounting plate 3.

[0029] As Figure 3 、 Figure 4As shown, the top of the arc-shaped plate 4 bends into an arc towards one side of the electric push rod 5, and the bottom of the arc-shaped plate 4 is fixedly connected to the bottom plate 1 through the first fixing plate 401. One end of the arc-shaped plate 4 close to the electric push rod 5 is fixedly connected to the bottom plate 1 through the second fixing plate 402. Extrusion bolts are threadedly connected to the corresponding positions of the arc-shaped plate 4 on the side walls near both ends of the mounting plate 3, and one end of the extrusion bolt penetrates through the inside of the mounting plate 3 and fits against the side wall of the arc-shaped plate 4. By releasing the extrusion between the mounting plate 3 and the arc-shaped plate 4, and then moving the mounting plate 3 along the inclined arc-shaped plate 4, the sliding block 302 can be driven to move accordingly.

[0030] During use, the workpiece can be conveniently placed on the top of the support plate 2, and then the electric push rod 5 is started to drive the bottom fixing block 6 to clamp and fix the workpiece. Then the extrusion push rod 702 is started, so that the extrusion push rod 702 extends to drive the extrusion plate 7 to move, and the extrusion push rod 702 passing through the center of the through plate 701 drives the punch to move, realizing the punching operation on the workpiece. When punching workpieces with different inclination angles, the extrusion bolts can be conveniently rotated to release the extrusion between the mounting plate 3 and the arc-shaped plate 4, and then the mounting plate 3 is moved along the inclined arc-shaped plate 4, which can drive the sliding block 302 to move accordingly. Then the sliding block 302 drives the extrusion plate 7 to adjust the angle through the extrusion push rod 702. At the same time, the threaded rod 301 can also be rotated to drive the sliding block 302 to move inside the sliding groove 303, so that the extrusion push rod 702 is driven to displace, realizing the adjustment of the position of the extrusion plate 7, and effectively adapting to the punching operations of workpieces with different inclination angles and positions.

The bottom extension end of the electric push rod 5 is spherically rotatably connected to the top of the fixing block 6 through a ball shaft 502. One side of the top of the bottom plate 1 is fixedly connected to one side of the rectangular hole 103 through a connecting plate 102. Adjusting blocks 601 are provided on both sides of the fixing block 6, and a sliding rod 602 is fixedly connected to the side of the adjusting block 601 close to the fixing block 6. The adjusting block 601 is slidably connected to the inside of the fixing block 6 through the adjusting block 601. The fixing block 6 can be inclined at any angle so that it can fit well with the top of the workpiece. At the same time, the adjusting block 601 can also be pulled to realize the adjustment of the position of the adjusting block 601, thereby expanding or shrinking the extrusion position of the workpiece.

[0032] When fixing workpieces of different sizes, the fixing nut 501 can be conveniently rotated to relieve the extrusion of the fixing nut 501 on the top plate 101. At this time, the electric push rod 5 can be conveniently moved inside the rectangular hole 103, so as to adjust the position of the fixing block 6 at the bottom of the electric push rod 5. At the same time, since the electric push rod 5 is connected to the fixing block 6 through a ball shaft 502, during use, the fixing block 6 can be tilted at any angle, enabling it to fit well with the top of the workpiece. At the same time, the adjusting block 601 can be pulled to adjust the position of the adjusting block 601, thereby expanding or shrinking the extrusion position of the workpiece, further adapting to workpieces of different sizes. And during use, the inclined block 201 can also be disassembled and replaced, so as to adjust the inclined block 201 with different inclination angles according to different workpieces for convenient fitting, and it can meet the fixing requirements of workpieces of different sizes.
