Detailed Description

Please refer to fig. 1, fig. 2A and fig. 3, which are perspective views, a structural diagram, a slide bar perspective view and a scissors structure perspective view of the present invention. As shown in the figure, the present invention comprises a base 1, two scissors structures 2 disposed at one end of the base 1, and a supporting structure 3. The base 1 has a first support frame 11 and a second support frame 12, the first support frame 11 is pivotally connected to a rod 13 and a swing arm 14, which is coupled to the rod 13 and has a u-shape, and the swing arm 14 is connected to the scissors structure 2. In this embodiment, the swing arm 14 is pivotally connected to the first support frame 11 at a lower edge thereof, so that the swing arm 14 can be configured to be rotatable.

One side of the first supporting frame 11 is provided with a horizontal positioning portion 111, the positioning portion 111 is provided with a bolt 15, and the bolt 15 is horizontally displaced and supported against the swing arm 14 by the rotation of the bolt 15 along the positioning portion 111, so as to adjust the swing angle of the swing arm 14. The swing arms 14 are respectively connected with a universal joint assembly 16, and the other ends of the universal joint assemblies 16 are connected with the scissors structure 2. When the rod 13 is pressed down, the swing arm 14 is driven, and the scissors structure 2 is driven by the universal joint assembly 16 to perform a cutting operation. Wing parts 17 are respectively arranged on two sides of the bottom edge of the base 1, bolts 18 are arranged on the wing parts 17 in a penetrating way, supporting pieces 19 are arranged at the bottom ends of the bolts 18, and the bolts 18 rotate along the wing parts 17 to enable the upper and lower displacement to be realized so as to adjust the height of the base 1.

The scissors structure 2 comprises two sets of upper blade 21 and lower blade 22 which are obliquely opposite, and a fixing seat 23, wherein one end of the upper blade 21 is pivoted to a proper position of the fixing seat 23, the other end of the upper blade is connected to the universal joint component 16, and the lower blade 22 is locked on the fixing seat 23 through a fixing part 24, so that different blades can be replaced by the lower blade 22 according to different cutting requirements (thickness of a plate).

In the supporting structure 3, the second supporting frame 12 of the base 1 is provided with an arc-shaped swinging piece 31, and the lower edge of the swinging piece 31 is pivoted to the second supporting frame 12, so that the swinging arm 14 can be in a rotatable state. The swing plate 31 is pivotally connected to a slide bar 33 with a front end being a supporting portion 331 (in the embodiment, the supporting portion 331 is trapezoidal) by a link 32 at a lower portion thereof, and is connected to a proper position of the rod 13 by a chain 34 at an upper portion thereof. Wherein, the sliding rod 33 is inserted into a bearing seat 35 disposed on the base 1. When the rod 13 presses down on the swinging piece 31, the sliding rod 33 is pushed by the connecting rod 32, so that the sliding rod 33 extends out towards the front end of the scissors structure 2 of the base 1.

Through the combination of the components, the plate cutting and bending device is formed. The plate is placed in the scissors structure 2, the scissors structure 2 is driven to generate the action of shearing the plate by pressing down the rod body 13, the slide rod 33 is driven to push towards the scissors structure 2 after the rod body 13 is pressed down continuously, the sheared part is folded by the propping part 331 at the front end of the slide rod 33, and a required trapezoidal notch is formed at the edge of the plate so as to coat the lap joint end of the corrugated plate and achieve the effect of edge folding. The operation of cutting and bending the plate is simpler and more labor-saving, the operation cost is reduced, and the operation efficiency is improved.

Please refer to fig. 4 and fig. 5, which are diagrams illustrating a usage status of the present invention. As shown in the figures, when the present invention is used, the rod 13 is pulled upwards to open the upper blade 21 and the lower blade 22 of the scissors structure 2, and the swing angle of the swing arm 14 is adjusted by the rotation of the bolt 15 along the positioning portion 111, so as to adjust the opening angle of the upper blade 21 and the lower blade 22 of the scissors structure 2. Since the rod 13 is connected to the swinging piece 31 by the chain 34, when the rod 13 is pulled upward, the swinging piece 31 is driven upward by the chain 34 to ensure that the sliding rod 33 is returned to the position. After the rod body 13 is pulled up, the base 1 is positioned at the construction position, and the plate 4 to be processed and cut is placed between the upper blade 21 and the lower blade 22 of the scissors structure 2 to be cut.

Please refer to fig. 6 and fig. 7, which are diagrams illustrating the clipping operation state according to the present invention. As shown in the figure, the plate 4 can be placed on the scissors structure 2, the rod body 13 can be pressed downwards, when the rod body 13 is pressed downwards, the swing arm 14 can be driven to swing, the universal joint assembly 16 is relatively driven, the upper blade 21 of the scissors structure 2 can swing towards the lower blade 22, the cutting action is formed, and therefore the required trapezoidal notch is cut at the edge of the plate 4. The lower blade 22 can be loosened and locked by the fixing member 24 from the fixing seat 23 to replace different blades according to different cutting requirements (thickness of the plate 4).

Please refer to fig. 8, which is a diagram illustrating a state of the propping action according to the present invention. As shown in the figures, after the aforementioned cutting operation is completed, the rod 13 is continuously pressed down to make the rod 13 press down the swinging piece 31, and after the swinging piece 31 swings downward, the sliding rod 33 is pushed by the connecting rod 32 to make the sliding rod 33 extend out from the scissors structure 2 at the front end, because the plate 4 has been cut out by the scissors structure 2 to form a trapezoidal notch, the supporting portion 331 of the sliding rod 33 can support the cut plate 4 upward, so that the cut plate 4 is folded. Because the slide bar 33 is inserted into a bearing seat 35 disposed on the base 1, the slide bar 33 can move more smoothly through the bearing seat 35.

The rod body 13 can be lifted upwards after the whole cutting and folding actions are finished, and the rod body 13 is connected to the swinging piece 31 through the chain 34, so that when the rod body 13 is lifted to a certain height, the swinging piece 31 can be lifted through the chain 34, and the swinging piece 31 is returned to be positioned.

Please refer to fig. 9, which is a perspective view of the board and the corrugated board of the present invention. As shown in the figure, the cut and kinked plate 4 of the invention is cut with the needed trapezoidal gap 41 at the edge for wrapping the plate 4 at the lap joint end of the wave plate 5, thereby achieving the function of edge folding.

The foregoing examples are intended to illustrate preferred embodiments of the present invention, but not to limit the scope of the present invention, and are intended to be covered by the scope of the present invention by simple modification and alteration.

In summary, the present invention uses the scissors structure connected with the rod body, and the sliding rod with the front end being the supporting part, to form the plate cutting and bending device. The edge of the plate is provided with the needed trapezoidal notch, so that the operations of cutting and bending the plate are simpler and more labor-saving, and the operation efficiency is higher.
