[0026] It should be noted that similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined or described in one drawing, it will not be necessary to further specifically discuss and describe it in the description of the subsequent drawings.

[0027] To solve the technical problems in the background art, as Figures 1-4 shown, the present application provides a technical solution: a film electric shear, characterized as follows:

[0028] The first connecting plate 1 is provided with a guiding groove 2 for accommodating the sliding of the connecting block 13. The second connecting plate 3 is fixedly connected to the first connecting plate 1 to form an enclosed space 4. The second connecting plate 3 and the first connecting plate 1 need to have a certain strength and load-bearing capacity, and the enclosed space 4 is used to accommodate the shearing part, the handle and other components. The first shearing part 5 and the second shearing part 6 are both arranged in the enclosed space 4, with a pair of scissors blades at one end and are respectively connected to the first handle 7 and the second handle 8 at the other end. The scissors blades and the handle can be integrally formed or fixedly connected by other means such as welding and riveting. The two shearing parts are hinged by a hinge part 9, and the first shearing part 5 and the second shearing part 6 form a device similar to an X shape. The air cylinder 10 is fixedly connected to the first connecting plate 1 and is used to provide power to drive the shearing part to perform a shearing action. Two limiting grooves 11 are symmetrically arranged on the second connecting plate 3 and have a certain included angle with the telescopic rod of the air cylinder 10 as the axis, and are used to limit the sliding range of the pin shaft 12. The ends of the first handle 7 and the second handle 8 are both provided with pin shafts 12, and the two pin shafts 12 slide in two different limiting grooves 11 respectively. One end of the connecting block 13 is connected to the hinge part 9, and the other end is connected to the telescopic rod of the air cylinder 10. The connecting block 13 is adapted to the guiding groove 2 and can slide along the guiding groove 2 under the push of the air cylinder 10.

[0029] When the air cylinder 10 works, the telescopic movement of its telescopic rod drives the connecting block 13 to slide along the guiding groove 2. The sliding of the connecting block 13 drives the hinge part 9 to move, and further drives the first shearing part 5 and the second shearing part 6 to expand and contract; the pin shaft 12 slides in the two limiting grooves 11 to limit the movement range of the first handle 7 and the second handle 8, realizing the relative movement of the first shearing part 5 and the second shearing part 6 and achieving the shearing function.

[0030] It should be noted that in some embodiments, as shown in the figure, the connecting block 13 is of a U-shaped structure. The groove of the U-shaped structure of the connecting block 13 is used to accommodate the hinge part 9, and its feature is that one side abuts against the guiding groove 2 and the other side abuts against the second connecting plate 3. The design of the connecting block 13 enables it to be stably fixed between the guiding groove 2 and the second connecting plate 3, ensuring that the hinge part 9 connected moves more smoothly during the movement process. The width of the connecting block 13 matches the width of the guiding groove 2 to ensure that the connecting block body can be smoothly inserted into the guiding groove 2.

[0031] Further, the roller 14 is disposed at one end of the connecting block 13 in contact with the guiding groove 2. The roller 14 is made of wear-resistant material, has a smooth surface, and its diameter is slightly smaller than the width of the guiding groove 2 to achieve smooth rolling. The bearing structure of the roller 14 enables it to roll freely in the guiding groove 2, reducing friction and wear. When the roller 14 rolls in the guiding groove 2, since the contact area between the roller 14 and the guiding groove 2 is small, the frictional force is small, making the connection structure smoother during movement. Effectively reducing the friction between the connecting block 13 and the guiding groove 2 and improving the movement performance of the connection structure.

[0032] It should be noted that the included angle between the two limiting grooves 11 is an acute angle range between 30° and 60°. The limiting grooves 11 are made of high-strength stainless steel material, having good wear resistance and corrosion resistance. When the two pin shafts 12 slide in the two limiting grooves 11 with an included angle respectively, the two pin shafts 12 drive the first handle 7 and the second handle 8 to pivot around the hinge shaft, forming relative approaching and separating, so that the first shearing portion 5 and the second shearing portion 6 perform closing and opening actions to complete shearing. The angle range of 30° - 60° is beneficial to improving the stability and reliability of the film electric shear, preventing too small an angle from being unfavorable for the opening of the shearing portion; too large an angle is unfavorable for smooth gradual opening, and with a slight movement of the telescopic rod, the large-angle opening of the shearing portion can be achieved, which is not conducive to control.

[0033] Further, the fixed seat 15 in this embodiment is made of metal material, having sufficient strength and stability. The fixed seat 15 is in an L shape, with its bottom end fixed on the workbench and its side connected to the first connecting plate 1. The side of the fixed seat 15 connected to the first connecting plate 1 is provided with an adjusting groove 16.

[0034] The adjusting groove 16 is a strip-shaped groove. As shown in the figure, multiple adjusting grooves 16 are provided in this embodiment, and the multiple adjusting grooves 16 are irregularly arranged, and the distances between adjacent adjusting grooves 16 can be unequal. The adjusting groove 16 is used to install bolts to connect the fixed seat 15 and the first connecting plate 1. Different positions of the adjusting groove 16 and the strip-shaped adjusting groove 16 can adjust the position of the first connecting plate 1, so as to facilitate adjusting the angle and position of the film electric shear as required.

[0035] It should be noted that the first handle 7 and the second handle 8 are respectively located on both sides of the connecting block 13, and there is a certain distance between them. In this embodiment, the minimum distance between the first handle 7 and the second handle 8 is L. This distance can be set according to actual usage requirements to ensure comfort and stability during gripping. The thickness of the connecting block 13 is T. The thickness T of the connecting block 13 is less than the minimum distance L between the first handle 7 and the second handle 8. Specifically, the thickness T of the connecting block 13 can be expressed as: T < L. This design ensures that when the shearing part needs to be closed, the connecting block 13 will not hinder the closing of the first handle 7 and the second handle 8, thereby improving the comfort and safety of use.

[0036] Although the embodiments of the present application have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present application. The scope of the present application is defined by the appended claims and their equivalents.
