[0002] Pipe cutters are a common tool used in pipeline installation and maintenance, primarily for cutting pipe fittings. Pipe cutters have blades that need to be replaced after a period of use. The ease of blade replacement significantly impacts user experience.

[0003] For example, Patent No. CN215968879U discloses a pipe cutter with convenient blade replacement. The cutter comprises a main handle and a secondary handle that are hinged to each other. The front end of the main handle is provided with a cutting blade, and the secondary handle is provided with a snap member for engaging the cutting blade. The main handle is provided with a detachable hinge shaft, and the cutting blade is hinged to the main handle via the hinge shaft. A limit member is provided at one end of the hinge shaft, and a limit hole that matches the limit member is provided on one side of the main handle. The limit member is disposed in the limit hole and engages with the main handle. In this structure, to remove the blade, the hinge shaft is removed by rotating and tightening the nut, thereby removing the cutting blade from the mounting slot. This makes blade disassembly and assembly inconvenient, time-consuming, and labor-intensive, making it very inconvenient to use. Utility Model Content

[0032] The following describes the technical solutions provided by various embodiments of the present application in conjunction with the accompanying drawings.

[0033] See Figures 1 to 7 The present invention provides a pipe cutter with a quick-detachable blade, comprising a housing 1 and a movable handle 2 hingedly connected to the housing 1. A blade 3 is detachably mounted on one end of the movable handle 2 disposed within the housing 1 via a quick-detach structure, which is used to achieve quick assembly and disassembly of the blade 3.

[0034] See Figure 2 and Figure 3The quick-release mechanism includes a slot 201 disposed within one end of the movable handle 2 and a locking member 4 movably mounted on the outer wall of the slot 201. A plug interface is provided on the outer side of the slot 201, connecting the slot 201 to the outside world. One end of the blade 3 is provided with a plug portion 301 that plugs into the slot 201. The locking member 4 is used to lock the plug portion 301, ensuring a secure connection between the plug portion 301 and the movable handle 2. To remove the blade 3, the locking member 4 unlocks the plug portion 301, allowing the blade 3 to be directly removed from the slot 201.

[0035] In some embodiments, as Figures 3 to 6 As shown, the locking member 4 is provided with a clamping head 401 that can be inserted into the insertion slot 201, and the movable handle 2 is provided with a through-hole for the clamping head 401 to pass through. The insertion portion 301 is provided with a slot 302 that engages with the clamping head 401. When the clamping head 401 engages with the slot 302, the locking member 4 locks the blade 3. This structure, through the clamping head 401 and the slot 302, locks the blade 3 stably and reliably.

[0036] In some embodiments, as Figures 3 to 5 As shown, the locking member 4 is hinged to the movable handle 2; one end of the locking member 4 is provided with a clamping head 401, and the other end of the locking member 4 is provided with a pressing portion 402. To unlock, the pressing portion 402 is pressed, and the locking member 4 rotates so that the clamping head 401 is disengaged from the locking groove 302. The hinged installation of the locking member 4 makes unlocking and locking very convenient.

[0037] In some embodiments, as Figure 3 As shown, a spring 5 is installed between the locking member 4 and the movable handle 2. The spring 5 is located at the end of the locking member 4 away from the clamping head 401. Under the elastic force of the spring 5, the spring 5 always tends to move the clamping head 401 toward the insertion slot 201. The spring 5 not only ensures that the clamping head 401 is stably engaged with the clamping slot 302, but also facilitates the reset of the locking member 4 after pressing the locking member 4.

[0038] In some embodiments, as Figures 3 to 5 As shown, a spring groove 202 is provided on the outer wall of the movable handle 2, and a spring positioning post 403 corresponding to the spring groove 202 is provided on the locking member 4. One end of the spring 5 is placed in the spring groove 202, and the other end is sleeved on the spring positioning post 403. This structure, through the cooperation between the spring groove 202 and the spring positioning post 403, limits the position of the spring 5, prevents the spring 5 from shifting, and ensures the stability of the structure.

[0039] In some embodiments, as Figure 3 and Figure 5As shown, a beveled push surface 404 is provided on one side of the clamping head 401; when the inserting portion 301 is inserted into the inserting slot 201, the inserting portion 301 can use the beveled push surface 404 to push the clamping head 401 toward the outside of the inserting slot 201, preventing the clamping head 401 from blocking the inserting portion 301 from entering the inserting slot 201. This structure, by providing the beveled push surface 404, eliminates the need to press the locking member 4 when inserting the blade, making the operation easier.

[0040] In some embodiments, as Figure 5 and Figure 7 As shown, the locking member 4 is symmetrically provided with a first hinge shaft 405 , the movable handle 2 is provided with an axis hole 203 adapted to the first hinge shaft 405 , and the first hinge shaft 405 is placed in the axis hole 203 ; the first hinge shaft 405 is located between the spring positioning column 403 and the clamping head 401 .

[0041] In some embodiments, as Figure 3 and Figure 4 As shown, the movable handle 2 is hinged to the housing 1 via a second hinge axis 6, which extends through the insertion slot 201. The end of the insertion portion 301 is provided with a U-shaped slot 303 adapted to the second hinge axis 6. The U-shaped slot 303, one end of which is open to the outside world, prevents the second hinge axis 6 from blocking the removal of the blade, ensuring the feasibility of the structure.

[0042] In some embodiments, as Figure 1 and Figure 2 As shown, the housing 1 is provided with a blade holder 101 corresponding to the blade 3, and the blade holder 101 is provided with a cutting groove 102 for the blade 3 to enter. A torsion spring 7 is installed between the housing 1 and the movable handle 2, which always tends to move the movable handle 2 away from the housing 1. A U-shaped frame 8 is hingedly connected to the end of the movable handle 2, and the U-shaped frame 8 can be installed on the housing 1 when the movable handle 2 is closed.

[0043] The same or similar parts between the various embodiments in this specification can be referred to each other, and each embodiment focuses on the differences from other embodiments.

[0044] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
