[0028] Embodiment 1:

[0029] As Figures 1 to 4 shown, this embodiment provides a cable stripping knife, which includes a knife handle 1 and a blade 2. The knife handle 1 has a cavity 3 for storing at least one blade 2, and spare blades can be stored in the cavity 3. If multiple blades are stored, a positioning structure can also be provided in the cavity 3 to prevent the blades from shaking in the cavity 3 after the number of blades 2 decreases. For example, elastic clamping arms can be provided in the cavity 3 to clamp the blade 2, or a spring and an abutting block can be provided. Under the action of the spring, the abutting block presses against the blade 2. Secondly, a finger holding part 8 is provided on the knife handle 1. When the user holds the knife handle 1, the fingers fit with the finger holding part 8.

[0030] The blade 2 is detachably connected to the knife handle 1. Specifically, it also includes a fixing member 11. The blade 2 is detachably connected to the knife handle 1 through the fixing member 11. Among them, the detachable connection includes at least one of snap connection, magnetic connection, threaded connection, and mortise and tenon connection. Preferably, threaded connection is adopted, so that the blade 2 and the knife handle 1 have better connection strength. A cutting edge part and a connecting part are provided on the blade 2, and a slot adapted to the connecting part is provided on the knife handle 1. After the connecting part is inserted into the slot, it can only move along the slot direction. The fixing member 11 includes a rotating operation end 111 and a threaded end 112. Among them, the threaded end 112 can be integrally injection-molded with a stud in the fixing member 11, and the rotating operation end 111 facilitates the user to perform a rotating operation by hand.

[0031] Secondly, at least a first through hole 12 for the threaded end 112 to pass through is provided on the knife handle 1, and at least a second through hole 13 for the threaded end 112 to pass through is provided on the blade 2. In this embodiment, the rotating operation end 111 includes an operation part and a rotating part. The outer diameter of the operation part is larger than that of the rotating part. The threaded end 112 is connected to the rotating part. The first through hole 12 can allow the operation part to pass through. After the blade 2 is fixed, the fixing member 11 will be embedded in the first through hole 12 and will not form a protrusion on the surface of the knife handle 1. The second through hole 13 can allow the rotating part to pass through, and the end face of the operation part close to the rotating part abuts against the blade 2. Among them, a threaded hole matching the threaded end 112 is provided on the back of the second through hole 13 on the blade 2 and / or a threaded hole matching the threaded end 112 is provided on the opposite side of the first through hole 12 on the knife handle 1. The blade 2 can be fixed in the slot through the fixing member 11 to prevent the blade 2 from being pulled out of the slot when stripping the cable.

[0032] An opening 4 communicating with the cavity 3 and allowing the blade 2 to pass through is provided on the tool handle 1, and a cover body 5 is provided corresponding to the opening 4. It should be understood that there are various positions for the opening 4. For example, the opening 4 is provided at the tail of the tool handle 1. Another example is that the opening 4 is provided at the finger gripping portion 8. In this embodiment, the opening 4 is provided on the opposite side of the finger gripping portion 8. In this way, the length of the opening 4 is relatively long, and it is more convenient to load and unload the blade 2.

[0033] The cover body 5 has a first state of blocking the opening 4 and a second state of opening the opening 4. When the cover body 5 is in the first state, the blade 2 is stored in the cavity 3 and will not fall out. When the cover body 5 is in the second state, the spare blade can be taken out from the opening 4. Through this setting, storing the spare blade in the cavity 3 can cope with the sudden situation of blade damage, improving the practicability and fault tolerance of the cable stripping knife; specifically, the user can conveniently carry an extra spare blade 2. When the current blade 2 has a problem, the user does not need to look for other tools or spend time to obtain a new blade 2, but can immediately take out the spare blade 2 from the cavity for replacement, thus greatly reducing the downtime and improving the work efficiency.

[0034] In addition, when technicians and electricians are working on-site, they usually need to carry a variety of tools. Integrating a storage function for a spare blade on the tool handle 1 can store blades different from the current blade, enriching the functionality of the product and improving the convenience of the product.

[0035] It should be understood that there are various structures for the cover body 5 to have these two states. For example, the cover body 5 is detachably connected to the tool handle 1. When the cover body 5 is connected to the tool handle 1, it is in the first state. When the cover body 5 is separated from the tool handle 1, it is in the second state. Another example is that one end of the cover body 5 is hinged to the tool handle 1, and the other end is detachably connected to the tool handle 1. When the cover body 5 rotates around its hinge center, it can switch between the first state and the second state. In this embodiment, the former structure is adopted. Among them, the detachable connection includes at least one of snap connection, magnetic connection, screw connection, and mortise and tenon connection. Among them, the snap connection includes snap-fastener connection and plug-in connection. In this embodiment, the snap connection is adopted. The front end of the cover body 5 is provided with a plug-in block, the tool handle 1 is provided with a plug-in hole corresponding to the plug-in block, the rear end of the cover body 5 is provided with an elastic clamping arm, and the tool handle 1 is provided with a clamping groove corresponding to the elastic clamping arm. During assembly, first insert the plug-in block into the plug-in hole, and then press to make the elastic clamping arm deform and insert into the clamping groove. After that, the elastic clamping arm resumes deformation and forms a snap connection with the clamping groove. When it is necessary to disassemble the cover body 5, just apply a certain force to lift the cover body 5.

[0036] A knife holder groove 6 communicating with the cavity 3 is provided on the knife handle 1. When the cover body 5 is in the second state, the knife holder groove 6 exposes at least part of the blade 2. In this embodiment, the knife holder groove 6 is a semi-circular notch, which is convenient for users to quickly access the blade. This not only improves the user experience, but also increases the overall durability and practical value of the cable stripping knife, making it an ideal choice for electricians and technicians.

[0037] Secondly, a shielding plate 7 adapted to the knife holder groove 6 is provided on the cover body 5. When the cover body 5 is in the first state, the shielding plate 7 shields the knife holder groove 6, making the cavity 3 a relatively closed chamber to prevent external moisture and debris from entering.

[0038] Furthermore, a knife sheath 9 detachably connected to the knife handle 1 is also included. Among them, the detachable connection includes at least one of snap connection, magnetic connection, threaded connection, and mortise and tenon connection. When not in use, the knife sheath 9 covers the outside of the blade 2 to protect the blade 2 and prevent the blade 2 from hurting the user. A guide head 10 is provided at the tip of the blade 2. When stripping the protective outer skin of the cable, first make a small cut in the protective outer skin, then insert the guide head 10 into the cable through the small cut, and then pull the knife handle 1 along the extension direction of the cable to cut the protective outer skin of the cable to the target length. Since the guide head 10 is very blunt, it can effectively prevent the tip of the knife from cutting the inner core of the cable when it enters the cable first.
