Description

Technical Field

[0001] This utility model relates to the field of binding technology, and in particular to a plum blossom-shaped binding device. Background Technology

[0002] In existing binding technologies, traditional binding devices mostly use ordinary straight or U-shaped staples. These staples provide relatively dispersed binding force on the materials after binding, which can easily lead to problems such as loose materials and curling corners. This is especially true for materials that need to be preserved for a long time or frequently consulted, as the binding stability is poor.

[0003] Traditional binding methods often lead to difficulties when binding thicker documents due to insufficient pressure plate length or inconvenience in applying pressure, sometimes even resulting in nails failing to penetrate the document. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a plum blossom-shaped binding device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a plum blossom-shaped binding device, comprising a base plate, a bracket rotatably connected to the base plate, a pressure plate rotatably connected to the bracket, a side plate rotatably connected to the pressure plate, a slot on one side of the side plate, a torsion spring fixedly connected to the central shaft at one end of the side plate, one end of the torsion spring fixedly connected to the pressure plate, a return spring fixedly connected to the bracket, the upper end of the return spring fixedly connected to the pressure plate, a compression spring fixedly connected to the base plate, the upper end of the compression spring fixedly connected to the bracket, and a pressure pin fixedly connected to one end of the pressure plate.

[0006] As a further description of the above technical solution: the bracket is provided with a sliding groove, a push plate is slidably connected to the sliding groove, a spring is fixedly connected to one side of the push plate, one end of the spring is fixedly connected to the bracket, one end of the bracket is provided with a nail groove, and one side of the base plate is provided with a guide hole.

[0007] As a further description of the above technical solution: a plum petal-shaped nail strip is placed in the cavity inside the bracket, and the nail groove is connected to the cavity inside the bracket.

[0008] As a further description of the above technical solution: a groove is provided above the bracket, and the reset spring is located in the groove inside the bracket.

[0009] As a further description of the above technical solution: the pressure pin is located above the nail groove, and the shape of the inner groove of the pressure pin is the same as that of the plum petal nail.

[0010] As a further description of the above technical solution: the spring is disposed in the cavity of the bracket.

[0011] As a further description of the above technical solution: the pressure plate is provided with a receiving groove, and the side plate is provided in the receiving groove of the pressure plate.

[0012] This utility model has the following beneficial effects: In this invention, the device is adaptable to materials of different thicknesses. With the pull-out and reset side plate, the length of the pressure plate can be increased when the material is thicker, making it easier for the user to apply pressure to complete the binding. The side plate can be stored in the receiving groove without affecting the normal use of the device, thus improving the practicality and flexibility of the device.

[0013] In this invention, the device enables continuous binding of plum blossom-shaped staples without the need for frequent manual adjustment of the staple position, greatly improving binding efficiency. At the same time, through the cooperation of the push plate and the spring, the staples are stably displaced during the binding process, ensuring the continuity and accuracy of the binding.

[0019] like Figures 1 to 4 As shown, a plum blossom-shaped binding device includes a base plate 1, a bracket 2 rotatably connected to the base plate 1, a pressure plate 3 rotatably connected to the bracket 2, a side plate 4 rotatably connected to the pressure plate 3, a slot 5 on one side of the side plate 4, a torsion spring 6 fixedly connected to the central shaft at one end of the side plate 4, one end of the torsion spring 6 fixedly connected to the pressure plate 3, a return spring 7 fixedly connected to the bracket 2, the upper end of the return spring 7 fixedly connected to the pressure plate 3, a compression spring 8 fixedly connected to the base plate 1, the upper end of the compression spring 8 fixedly connected to the bracket 2, and a pressure pin 14 fixedly connected to one end of the pressure plate 3.

[0020] In addition, in this embodiment, the base plate 1 is rotatably connected to the bracket 2, pressure plate 3, and side plate 4 via a pivot and hinge, and the torsion spring 6, return spring 7, and compression spring 8 provide elastic force; the effect is that each component can rotate and return to its original position, thus forming the basic binding structure.

[0021] Specifically, the bracket 2 is provided with a sliding groove 9, and a push plate 10 is slidably connected to the sliding groove 9. A spring 11 is fixedly connected to one side of the push plate 10. One end of the spring 11 is fixedly connected to the bracket 2. One end of the bracket 2 is provided with a nail groove 12, and one side of the base plate 1 is provided with a guide hole 13.

[0022] In this embodiment, the push plate 10 slides in the groove 9, the spring 11 pushes the push plate 10 to move the nail bar, the nail groove 12 allows the nail to pass through, and the guide hole 13 guides the nail to bend, thereby realizing the movement of the nail bar and the bending of the nail for fastening.

[0023] Specifically, a plum petal-shaped nail strip is placed in the cavity inside the bracket 2, and the nail groove 12 is connected to the cavity inside the bracket 2.

[0024] In a preferred embodiment, the cavity accommodates the nail strip, and the nail groove 12 provides a downward pressing channel for the nail, which ensures that the nail strip is placed stably and the nail can be pressed down smoothly.

[0025] Specifically, a groove is provided on the top of the bracket 2, and the reset spring 7 is located in the groove inside the bracket 2.

[0026] Specifically, the pressure pin 14 is located above the nail groove 12, and the shape of the inner groove of the pressure pin 14 is the same as that of the plum petal nail.

[0027] With this setup, the pressure pin 14 is aligned with the nail in the nail groove 12 and pressed down, ensuring that the nail is precisely pressed down and the binding position is accurate.

[0028] Specifically, spring 11 is located inside the cavity of bracket 2.

[0029] Among them, the extension and retraction of spring 11 drives the push plate 10 to move in the cavity, so that the push plate 10 exerts a uniform pushing force on the nail bar, and the nail bar moves smoothly.

[0030] Specifically, the pressure plate 3 is provided with a receiving groove, and the side plate 4 is located in the receiving groove of the pressure plate 3.

[0031] In this embodiment, the side plate 4 does not occupy extra space when not in use and does not affect the normal operation of the pressure plate 3.

[0032] Working principle: When in use, first pull the push plate 10 to one side to slide on the slide groove 9 and compress the spring 11. Then place the plum petal-shaped staple strip in the cavity of the bracket 2. Then release the push plate 10. The spring 11 rebounds and causes the push plate 10 to abut against one side of the plum petal-shaped staple strip to push the plum petal-shaped staple strip, thereby ensuring that the plum petal-shaped staple strip can be pushed and displaced during the binding process to achieve continuous binding. Then place the material to be rotated at one end of the base plate 1 and below its nail groove 12. Then press down on the pressure plate 3 and compress the return spring 7. When the pressure needle 14 at one end of the pressure plate 3 contacts the petal-shaped nail strip, it drives the bracket 2 to rotate on the base plate 1. When one end of the bracket 2 is attached to the material, it continues to apply pressure to the pressure plate 3, so that the pressure needle 14 presses down on a group of nails in the petal-shaped nail strip. As the nail is pressed down, it penetrates the material. When the lower end of the nail contacts the guide hole 13, the guide hole 13 guides the two ends of the nail to bend to both sides to complete the binding of the material. When the bound materials are thick, the side plate 4 is pulled out through the slot 5 and the torsion spring 6 is twisted. When the side plate 4 is rotated to 180 degrees, the pressure plate 3 can be pressed down. The side plate 4 increases the length of the pressure plate 3, making it easier for the user to bind thicker materials. After binding, the side plate 4 is released, and the torsion spring 6 twists in the opposite direction to reset the side plate 4 in the receiving groove of the pressure plate 3 for storage.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
