[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-4 The utility model provides a technical solution: it includes a blade 10, one end of which is rotatably connected to a base 1, a clamping plate 2 is rotatably connected to the base 1, a guide groove 12 is provided on the clamping plate 2, the other end of the blade 10 is slidably connected to the guide groove 12, and the guide groove 12 is inclined.

[0020] When the user needs to use the blade 10, the clamping plate 2 is rotated to make the other end of the blade 10 slide along the guide groove 12. Since the guide groove 12 is inclined, the other end of the blade 10 will move closer to or away from the axis of the base 1 when sliding along the guide groove 12, thereby making the two ends of the blade 10 extend and retract between the base 1 and the base 1, so that it can be extended to unpack the express when needed, and the blade 10 can be retracted after use to prevent its blade from being exposed and scratching people or things.

[0021] By adopting the above design, the blade 10 is stored between the base 1 and the clamping plate 2 in the non-working state, avoiding the potential safety hazard caused by the blade 10 being exposed to the outside, thereby improving the safety of the device. The blade 10 can be easily extended and retracted through simple sliding and fixing operations without complicated operating steps, making the operation of the device easier.

[0022] Specifically, a telescopic slot 3 is provided on the top surface of the base 1, and a connecting column 4 is provided on the top surface of the telescopic slot 3. A hole is provided on the top surface of the splint 2, and a connecting bolt 5 is inserted in the hole. The connecting bolt 5 is threadedly connected to the connecting column 4. A limiting slot 6 is provided on the top surface of the base 1, and a limiting block 7 is provided on the bottom surface of the splint 2. The limiting block 7 is inserted in the limiting slot 6, and the limiting block 7 can only slide along the opening direction of the limiting slot 6. A lower splint 8 and an upper splint 9 are provided on both sides of the blade 10. Sockets are provided on the bottom surface of the base 1 and one end of the lower splint 8, and a rotating bolt 11 threadedly connected to one end of the upper splint 9 is inserted in the socket. A guide bolt 13 is inserted in the guide groove 12. A socket adapted to the guide bolt 13 is provided at the other end of the upper splint 9, and the guide bolt 13 passes through the socket and is threadedly connected to the lower splint 8.

[0023] The coordinated use of the limit groove 6 and the limit block 7 ensures the stability and accuracy of the splint 2 during the sliding process. By rotating the connecting bolt 5 and the rotating bolt 11, the device can be easily disassembled and assembled, which is convenient for internal cleaning and maintenance, thereby extending its service life to a certain extent.

[0024] Further, refer to Figure 3 and Figure 4 One end of a return spring 14 is fixedly connected to the limiting groove 6 , and the other end of the return spring 14 abuts against the limiting block 7 .

[0025] By adopting the above design, when the rotating clamp 2 makes the blade 10 extend, the limit block 7 will compress the reset spring 14, causing it to deform and accumulate elastic potential energy. After use, it is only necessary to loosen the clamp 2, and the reset spring 14 will convert the elastic potential energy previously accumulated into kinetic energy, driving the limit block 7 to reset, and then driving the clamp 2 to reset, so that the blade 10 is automatically recovered, making the use of the device more convenient, and the blade 10 can be always stored between the base 1 and the clamp 2 under normal circumstances, which can prevent the blade 10 from extending from between the base 1 and the clamp 2 due to non-human factors and scratching people or things, thereby further improving the safety of the device.

[0026] Working principle:

[0027] In the initial state, one end of the blade 10 is connected to the base 1 through a rotating connection, and the other end is slidably connected to the guide groove 12 opened on the splint 2. Since the guide groove 12 is opened at an angle, the blade 10 is in a non-working state at this time, that is, part of the blade 10 does not protrude from the plane of the splint 2.

[0028] When in use, the splint 2 is manually pushed to slide along the limit groove 6 on the top surface of the base 1. With the cooperation of the limit block 7 and the limit groove 6, the splint 2 can only slide along the preset direction. As the splint 2 slides, the other end of the blade 10 gradually extends out of the plane of the splint 2 under the guidance of the guide groove 12. At this time, the blade 10 is in a working state and can be used to cut the seal of the express box. At this time, align the blade 10 with the seal of the express box for cutting.

[0029] After use, the clamping plate 2 is released, the limit block 7 is pushed back under the action of the return spring 14, and the blade 10 is automatically retracted into the clamping plate 2.
