[0037] This utility model provides a handheld hole punch, such as Figures 1-4 As shown, it includes a handle part 3, an opening part 1, and a punching part 2; the punching part 2 and the opening part 1 are detachably installed on both sides of the handle part 3; the opening part includes a cutting and retaining structure, which can cut the packaging bag to form a bag hole and retain the cut packaging bag film in the cutting and retaining structure; the punching part 2 is used to pass through the bag hole to punch a hole for the object inside the packaging.

[0038] The punched part 2 is detachably connected to the handle part 3 via a threaded structure; the opening part 1 is detachably connected to the handle part 3 via a threaded structure. Specifically, the punched part 2 is connected to one side of the handle part 3 via a first thread 23, and the opening part 1 is connected to the other side of the handle part 3 via a second thread 16.

[0039] The punching part 2 includes a punching post 21 and a limiting piece 22. One end of the punching post 21 is used to punch holes in objects inside the packaging, and the other end is detachably connected to the handle part 3. The limiting piece 22 is located between one end of the punching post 21 and the handle part 3. Specifically, the punching post 21 is the component that directly performs the punching operation, and the limiting piece is fitted onto the punching post 21 to limit the depth or position of the punching, preventing the punch from being too deep.

[0040] The opening 1 further includes a main body 17, a movable outer shell 13, and a spring 14; the cutting and retaining structure includes an annular blade 11; one end of the main body 17 is detachably connected to the handle 3, and the movable outer shell 13 is slidably mounted on the other end, with the annular blade 11 installed inside the movable outer shell 13; the spring 14 is fitted onto the main body 17, with one end of the spring 14 abutting against the movable outer shell 13 and the other end abutting against a protrusion 18 on the main body 17, in a preferred embodiment, the protrusion 18 being a nut structure.

[0041] The opening 1 also includes a retaining spring 15. The other end of the spring 14 abuts against the protrusion 18 on the main body 17 through the retaining spring 15. Specifically, the retaining spring 15 is used to fix the position of components such as springs to prevent them from falling off.

[0042] The handheld punch further includes a push rod 12, which is slidably disposed within the opening 1 and coaxially arranged with the annular blade 11. The push rod 12 has an extended state and a retracted state. When the push rod 12 is in the extended state, the end of the push rod 12 extends beyond the plane of the blade tip 111 of the annular blade 11. When the push rod 12 is in the retracted state, the end of the push rod 12 does not reach the plane of the blade tip 111 of the annular blade 11.

[0043] The annular blade 11 includes a blade body 112 and a plurality of blade tips 111, which are arranged in a ring and located on the blade body 112; in a preferred embodiment, the blade tips 111 are integrally connected to the blade body.

[0044] The blade tip 111 includes a cutting portion 1111 and a retention portion 1112; the thickness of the cutting portion 1111 is less than the thickness of the retention portion 1112, and the annular diameter formed by the multiple cutting portions 1111 is greater than the annular diameter formed by the multiple retention portions 1112; in a preferred embodiment, the cutting portion 1111 and the retention portion 1112 are transitionally connected, that is, the annular diameter formed by the tips of the multiple cutting portions 1111 gradually decreases to the annular diameter formed by the multiple retention portions 1112.

[0045] In a preferred embodiment, the handle portion 3 includes a long, straight handle, which facilitates handheld operation and provides a stable grip for punching holes. The handheld punch is a metal punch.

[0046] The working principle of this utility model is as follows:

[0047] In use, the operator holds the handle and first cuts the packaging bag using the opening 1. Specifically, the movable outer shell 13 is aligned with the position on the auricularia auricula-judae bag where a hole needs to be punched, so that the movable outer shell 13 abuts against the auricularia auricula-judae bag. The handle is pressed towards the auricularia auricula-judae bag. At this time, since the movable outer shell 13 is slidably mounted on the main body 17 and is already abutting against the auricularia auricula-judae bag, the movable outer shell 13 does not move relative to the auricularia auricula-judae bag, but the annular blade 11 will move relative to the auricularia auricula-judae bag until it cuts into the bag. At this time, the spring 14 is in a compressed state. Figure 5 As shown, and because the annular diameter formed by the cutting section 1111 is larger than the annular diameter formed by the plurality of retention sections 1112, the packaging bag (usually a plastic film) cut by the cutting section 1111 will be stuck in the retention section 1112 and collected by the opening 1. After the operator detaches the movable outer shell 13 from the auricularia auricula-judae bag, the elastic restoring force of the spring 14 returns the movable outer shell and the annular blade 11 to their initial positions, completing one punching operation.

[0048] After the auricularia auricularia bag is opened, the operator uses the punching part 2 to punch holes in the auricularia auricularia. Specifically, the operator holds the handle and aligns the punching part 2 with the position where the packaging bag has been cut and removed by the opening part 1. This position is where the auricularia auricularia needs to be punched. The punching pin pierces the auricularia auricularia under the pressure of the operator's hand. During this process, the punching pin 21 first contacts the auricularia auricularia and punches a hole. After the limiting plate contacts and abuts against the auricularia auricularia, the limiting plate prevents the punching pin from penetrating too deeply, ensuring the appropriate punching depth.

[0049] It is worth noting that the punching part 2 of this utility model can also be used to punch holes in shiitake mushrooms. Since shiitake mushrooms do not require cutting packaging bags, the punching part 2 can be used directly when punching holes in shiitake mushrooms.

[0050] In addition, because this utility model also includes a push rod 12, when the push rod 12 switches from the retracted state to the extended state, the push rod 12 will push out the plastic film that is stuck in the retention part 1112 and collected by the opening part 1 from the opening part 1, thereby cleaning the opening part 1. In a preferred embodiment, the switching between the retracted and extended states can be driven by gravity. In another preferred embodiment, the push rod 12 is connected to one end of a handle, and the other end of the handle extends radially outward from the main body 17 and finally passes through the main body 17, serving as a handle for switching the retracted and extended states of the push rod 12. The operator can switch the push rod 12 between the retracted and extended states by pushing and pulling the handle.

[0051] In summary, this invention utilizes the elastic potential energy of a spring at the opening. When the handle is pressed, the spring stores and releases energy, assisting the punching needle to penetrate the mushroom bag or substrate more easily and smoothly. Compared to purely manual pressing, it is less strenuous to operate and has relatively higher punching efficiency. This invention, by using a push rod 12 at the opening, solves the problem of quickly removing and recycling the plastic film collected from the mushroom substrate opening, facilitating hygiene management at the operating site. Furthermore, by employing a threaded structure on both sides of the handle, this invention allows for the replacement of matching opening and punching parts according to the required punching size, achieving the desired process.

[0052] This utility model's punching tool allows for the removal of the plastic film before punching, significantly improving punching quality and work efficiency. It is easy to operate, lightweight, and convenient to hold, allowing for flexible punching on auricularia auricula-judae bags or substrates, without limitations of site or space, even in small cultivation areas. Compared to existing punching tools on the market that produce inconsistent hole depths, this utility model allows for precise control of hole depth and diameter. Generally, auricularia auricula-judae cultivation requires holes of 1-2 cm in diameter and 2-3 cm in depth. The handheld punching tool, through its design, accurately punches holes meeting these requirements, ensuring better contact between the auricularia auricula-judae mycelium and the culture medium. This utility model is hygienic and safe, made of non-toxic and harmless stainless steel, and will not pollute the auricularia auricula-judae growth environment. It also includes replaceable punching needles for easy disassembly and cleaning, facilitating disinfection before and after use and reducing the risk of contamination by other microorganisms.
