Description

Technical Field

[0001] This application relates to the field of cutting technology, specifically to an electronic cutting knife with built-in blade replacement. Background Technology

[0002] An electric cutter is a handheld knife that uses electrical energy to heat up and cut. There are two main types: a simpler type has a heating wire inside the blade that heats up when electricity is applied. The advantages of this type are its low price, low cost, and simple structure. The disadvantages are that the blade is relatively thick, preheating is slow, and it can only be used to cut foam products. There are also modified soldering irons with smaller blades on the head, suitable for cutting smaller products. Another type uses the resistance of the blade to generate heat through a large current. This type of electric cutter has a very short preheating time; the blade reaches a red-hot state in just a few seconds, making it highly efficient.

[0003] Existing electric cutters are all installed in a toolbox, along with the blades and other related equipment. When workers need to change the cutter blades, they have to retrieve them from the toolbox, making the entire replacement process cumbersome and inefficient.

[0004] Therefore, it is necessary to provide an electronic cutter with built-in blade replacement to solve the above problems. Summary of the Invention

[0005] In view of the above-mentioned problems in the prior art, the purpose of this application is to provide an electronic cutter with built-in blade replacement to solve the problems mentioned in the background art.

[0006] The technical solution adopted by this application to solve its technical problem is: an electronic cutter with built-in blade replacement, including a cutter body, a cutter disc rotatably connected to the upper front end of the cutter body, and at least three blade groups are installed at intervals along the circumferential direction on the front end face of the cutter disc.

[0007] The blade assembly includes a blade fixedly connected to the front end face of the blade disc. The rear end of the blade is fixedly connected to a cathode contact and an anode contact. Both the cathode contact and the anode contact extend rearward to protrude from the rear end face of the blade disc.

[0008] When the cutter head rotates, the cutter assembly will pass through the conductive end and become electrically connected to the conductive end. The cathode contact and anode contact of the electrically connected cutter assembly will simultaneously contact the conductive end.

[0009] Furthermore, the end of the cutter body near the cutter disc is a conductive end, and the top of the conductive end is concentrically provided with an arc-shaped cathode guide rail and an anode guide rail, with the cathode guide rail on one side of the anode guide rail.

[0010] The cathode contact can pass through the cathode guide rail and make contact with the cathode guide rail as the cutter head rotates, and the anode contact can pass through the anode guide rail and make contact with the anode guide rail as the cutter head rotates.

[0011] Furthermore, the cathode and anode contacts, as well as the cathode and anode rails, are all concentrically arranged.

[0012] Furthermore, the material of the cutter head is plastic.

[0013] Furthermore, a positioning block extends upward from the top of the cutter body, and a connecting shaft is rotatably mounted on the positioning block, with one end of the connecting shaft fixedly connected to the center of the cutter disc.

[0014] Furthermore, a limiting hole is provided at one end of the conductive end, and a handle screw that abuts against the outer peripheral wall of the cutter head is installed in the limiting hole.

[0015] The beneficial effects of this application are as follows: This application provides an electronic cutter with built-in blade replacement. By setting a rotatable cutter head, all the blades that need to be replaced frequently are installed together. The blades can be switched by rotating the cutter head and fixing it. The whole process is simple and efficient. It solves the technical problem that existing electric cutters are installed in a toolbox, along with the blades and other related equipment. When the operator needs to replace the cutter blades, they still need to retrieve them from the toolbox. The whole replacement process is cumbersome and the replacement efficiency is low.

[0016] In addition to the purposes, features, and advantages described above, this application has other purposes, features, and advantages. A further detailed description of this application will be provided below with reference to the figures. Attached Figure Description

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0029] like Figure 1-6 As shown, this application provides a technical solution: an electronic cutter with built-in blade replacement, including a cutter body 1, a cutter disc 2 rotatably connected to the upper front end of the cutter body 1, and at least three blade sets 21 are installed at intervals along the circumferential direction on the front end face of the cutter disc 2.

[0030] The blade assembly 21 includes a blade 211 fixedly connected to the front end face of the blade disc 2. The rear end of the blade 211 is fixedly connected to a cathode contact 212 and an anode contact 213. Both the cathode contact 212 and the anode contact 213 extend rearward to protrude from the rear end face of the blade disc 2.

[0031] When the cutter head 2 rotates, the cutter assembly 21 will pass through the conductive end 12 and be electrically connected to the conductive end 12. The cathode contact 212 and anode contact 213 of the electrically connected cutter assembly 21 will simultaneously contact the conductive end 12.

[0032] The end of the cutter body 1 closest to the cutter disc 2 is a conductive end 12. The top of the conductive end 12 is concentrically provided with an arc-shaped cathode guide rail 122 and an anode guide rail 123, with the cathode guide rail 122 on one side of the anode guide rail 123.

[0033] The cathode contact 212 can rotate with the cutter head 2, pass through the cathode guide rail 122, and contact the cathode guide rail 122. The anode contact 213 can rotate with the cutter head 2, pass through the anode guide rail 123, and contact the anode guide rail 123.

[0034] The cathode contact 212 and anode contact 213, as well as the cathode rail 122 and anode rail 123, are all concentrically arranged.

[0035] The cutter head 2 is made of plastic, which serves as insulation.

[0036] A positioning block 11 extends upward from the top of the cutter body 1. A connecting shaft 3 is rotatably mounted on the positioning block 11, and one end of the connecting shaft 3 is fixedly connected to the center of the cutter head 2.

[0037] A limiting hole 121 is provided at one end of the conductive end 12, and a handle screw 4 that abuts against the outer peripheral wall of the cutter head 2 is installed in the limiting hole 121.

[0038] In one embodiment, the required blades 211 are installed on different blade sets 21. The blade disc 2 is rotated so that the cathode contact 212 on the blade set 21 to be used is in the cathode guide rail 122 and the anode contact 213 is in the anode guide rail 123. The handle screw 4 is screwed into the limiting hole 121 and pressed against the outer peripheral wall of the blade disc 2 to prevent the blade disc 2 from rotating. At this time, the blade set 21 forms a circuit with the conductive end 12. The switch on the cutter body 1 is pressed, and the blades 211 on the blade set 21 are energized and begin to heat up, so that the operation can be carried out.

[0039] When it is necessary to replace the blade set 21 for operation, loosen the handle screw 4, place the cathode contact 212 on the replacement blade set 21 in the cathode guide rail 122 and the anode contact 213 in the anode guide rail 123, tighten the handle screw 4, and press the switch on the cutter body 1 to turn on the power and start the operation.

[0040] In summary, this device, with its rotatable cutter head, houses all the frequently used blades. Blade switching is achieved simply by rotating and fixing the cutter head. The entire process is simple and efficient, solving the technical problem of existing electric cutting tools being stored in a toolbox along with the blades and other related equipment. This cumbersome process, characterized by low efficiency, requires operators to retrieve the blades from the toolbox for replacement.

[0041] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
