Description

Technical Field

[0001] This utility model belongs to the technical field of new construction tools, and specifically relates to a wire stripping device. Background Technology

[0002] In engineering, especially in electromechanical, installation, plumbing, decoration, and renovation projects, it is often necessary to strip the insulation from electrical wires. Currently, the task of stripping the insulation from wires on construction sites or in other scenarios is done with scissors and pliers. In practice, using scissors and pliers to strip the insulation from wires is somewhat stiff and clumsy; they have enough force but lack the dexterity. When using traditional scissors and pliers to strip the outer insulation of wires, it is often difficult to control the force, resulting in damage to the internal metal wires (copper wires), leaving small cuts that can lead to changes in resistance and safety hazards in the long term. Utility Model Content

[0003] The main purpose of this invention is to provide a wire stripping device that addresses the problem that workers on construction sites only have two relatively crude options when stripping the insulation of wires: scissors and pliers. This wire stripping device allows for more precise operation when stripping the insulation, effectively reducing the risk of cutting and damaging the internal metal wires and leaving tiny cuts. It also prevents these tiny cuts from becoming weak points due to changes in resistance over time.

[0004] This utility model provides a wire stripping device, comprising:

[0005] Thumb sleeve, used to be worn over the thumb;

[0006] A blade is mounted on the thumb sleeve;

[0007] Index finger sleeve, used to be worn on the index finger; and

[0008] A gasket is provided on the index finger sleeve, the gasket having a limiting groove that mates with an electrical wire, the limiting groove being located at the second joint of the index finger;

[0009] The thumb sleeve and the index finger sleeve are respectively used to be worn on the thumb and index finger of the same hand. With the coordinated operation of the thumb and index finger of the same hand, the blade can cut the insulation shell of the wire located in the limiting groove.

[0010] In one embodiment, the thumb sleeve is elastic, allowing it to elastically conform to the thumb; and / or

[0011] The index finger sleeve is elastic, so that it can fit snugly against the index finger.

[0012] In one embodiment, the thumb sleeve is made of plastic, rubber, or resin; and / or

[0013] The index finger sleeve is made of plastic, rubber, or resin.

[0014] In one embodiment, the thumb sleeve is a hollow structure with one end open and the other closed; and / or

[0015] The index finger sleeve is a hollow structure with one end open and the other end closed.

[0016] In one embodiment, the thumb sleeve is a hollow structure with one end open and the other end closed, and the index finger sleeve is a hollow structure with one end open and the other end closed.

[0017] The opening of the thumb sleeve is located at the second phalanx of the thumb; and / or

[0018] The opening end of the index finger sleeve is located at the third joint of the index finger.

[0019] In one embodiment, a blade holder is further included, which is disposed on the thumb sleeve, and the blade is detachably connected to the blade holder.

[0020] In one embodiment, there are multiple blades, and the blades of the multiple blades have different cutting edges.

[0021] In one embodiment, the blade holder has a snap-fit, and the end of the blade away from the cutting edge has a fixing plate, the snap-fit ​​being engaged with the fixing plate; or

[0022] The blade holder has a threaded hole, and the end of the blade away from the cutting edge has a threaded portion, which is threadedly connected to the threaded hole.

[0023] In one embodiment, the gasket includes two straight segments and an arc segment connecting the two straight segments, the arc segment having the limiting groove.

[0024] In one embodiment, the gasket is made of metal.

[0025] When using the aforementioned wire stripping device, first, place a thumb sleeve containing the blade and an index finger sleeve containing a pad on the thumb and index finger of the same hand, respectively. Then, place the wire whose insulation needs to be cut into the limiting groove of the pad on the index finger sleeve. Next, with the coordinated operation of the thumb and index finger of the same hand, the blade cuts the insulation of the wire located in the limiting groove, and finally peels the cut insulation off the wire. Because finger strength control is the most flexible and sensitive in the human body, and the thumb and index finger also provide strength, it can perform precise, sensitive, and relatively forceful operations. Therefore, the blade of the aforementioned wire stripping device can make relatively precise cuts to the insulation of the wire (the cutting position can be rolled during the cutting process), effectively reducing the probability of leaving small cut damage on the metal wire.

[0026] The aforementioned wire stripping device, through detailed research on finger joints, provides a more precise finger-like tool, replacing the traditional, rather crude methods of stripping insulation from metal wires using scissors and pliers. This significantly reduces operational errors associated with scissors and pliers, ensuring a more precise stripping operation. This device solves the problem on construction sites where workers only have scissors and pliers as relatively crude options for stripping wire insulation. It ensures a more precise stripping operation, effectively reducing the risk of cutting the internal metal wires and leaving tiny cuts. This prevents these small cuts from becoming weak points over time due to changes in resistance.

[0027] Furthermore, traditional scissors and pliers usually leave a certain amount of insulation residue after cutting, which workers often have to pull repeatedly to remove. This method can easily cause damage to the internal metal wire due to repeated pulling. The aforementioned wire stripping device, however, can roll over the cutting area during the cutting process, avoiding the presence of excess insulation and further reducing the probability of damage to the metal wire. In addition, traditional scissors and pliers are not suitable for applications with limited space, while the aforementioned wire stripping device is an ergonomically designed portable tool based on the characteristics of human fingers, making it usable even in confined spaces.

[0037] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0038] like Figures 1-4 As shown, this utility model discloses an embodiment of a wire stripping device. This wire stripping device is worn on the thumb 700 and index finger 800. Wherein, as... Figure 8 and Figure 9 As shown, 700 represents the thumb, 800 represents the index finger, and 900 represents the web of the hand. The thumb 700 includes a first phalanx 710 and a second phalanx 720, with a thumb nail 730 on the first phalanx 710. The index finger 800 includes a first phalanx 810, a second phalanx 820, and a third phalanx 830, with an index finger nail 840 on the first phalanx 810.

[0039] The wire stripping device includes a thumb sleeve 200, a blade 300, an index finger sleeve 400, and a washer 500. The thumb sleeve 200 is fitted onto the thumb 700. The blade 300 is mounted on the thumb sleeve 200. The index finger sleeve 400 is fitted onto the index finger 800. The washer 500 is mounted on the index finger sleeve 400. The washer 500 has a limiting groove 510 that mates with the wire. The limiting groove 510 is located at the second phalanx 820 of the index finger 800. The thumb sleeve 200 and index finger sleeve 400 are fitted onto the thumb 700 and index finger 800 of the same hand, respectively. With the coordinated operation of the thumb 700 and index finger 800 of the same hand, the blade 300 can cut the insulation of the wire located in the limiting groove 510.

[0040] When using the aforementioned wire stripping device, first, place a thumb sleeve 200 containing a blade 300 and an index finger sleeve 400 containing a pad 500 on the thumb 700 and index finger 800 of the same hand, respectively. Then, place the wire whose insulation needs to be cut into the limiting groove 510 of the pad 500 of the index finger sleeve 400. Next, with the coordinated operation of the thumb 700 and index finger 800 of the same hand, the blade 300 cuts the insulation of the wire located in the limiting groove 510. Finally, peel the cut insulation off the wire. Since finger strength control is the most flexible and sensitive in the human body, and the thumb 700 and index finger 800 also provide strength, it can perform precise, sensitive, and relatively forceful operations. Therefore, the blade 300 of the aforementioned wire stripping device can make relatively precise cuts to the insulation of the wire (the cutting position can be rolled during the cutting process), which can effectively reduce the probability of leaving small cut damage on the metal wire.

[0041] The aforementioned wire stripping device, through detailed research on finger joints, provides a more precise finger-like tool, replacing the traditional, rather crude methods of stripping insulation from metal wires using scissors and pliers. This significantly reduces operational errors associated with scissors and pliers, ensuring a more precise stripping operation. This device solves the problem on construction sites where workers only have scissors and pliers as relatively crude options for stripping wire insulation. It ensures a more precise stripping operation, effectively reducing the risk of cutting the internal metal wires and leaving tiny cuts. This prevents these small cuts from becoming weak points over time due to changes in resistance.

[0042] Furthermore, traditional scissors and pliers usually leave a certain amount of insulation residue after cutting, which workers often have to pull repeatedly to remove. This method can easily cause damage to the internal metal wire due to repeated pulling. The aforementioned wire stripping device, however, can roll over the cutting area during the cutting process, avoiding the presence of excess insulation and further reducing the probability of damage to the metal wire. In addition, traditional scissors and pliers are not suitable for applications with limited space, while the aforementioned wire stripping device is an ergonomically designed portable tool based on the characteristics of human fingers, making it usable even in confined spaces.

[0043] In this embodiment, the thumb sleeve 200 is made of plastic, rubber, or resin. The index finger sleeve 400 is also made of plastic, rubber, or resin. This facilitates the manufacture of the aforementioned wire stripping device. In other embodiments, when one of the thumb sleeve 200 and the index finger sleeve 400 is made of plastic, rubber, or resin, the other can be made of a material other than plastic, rubber, or resin. Specifically, in this embodiment, the thumb sleeve 200 and the index finger sleeve 400 are made of the same material. This further facilitates the manufacture of the thumb sleeve 200 and the index finger sleeve 400. It is understood that in other embodiments, the thumb sleeve 200 and the index finger sleeve 400 may also be made of different materials.

[0044] In this embodiment, the thumb sleeve 200 is elastic, allowing it to elastically and tightly adhere to the thumb 700. The index finger sleeve 400 is elastic, allowing it to elastically and tightly adhere to the index finger 800. In other embodiments, when one of the thumb sleeve 200 and the index finger sleeve 400 is elastic, the other may not be elastic. This makes it very convenient for the aforementioned wire stripping device to be securely fitted onto the finger. It is understood that in other embodiments, both the thumb sleeve 200 and the index finger sleeve 400 may be non-elastic, and the aforementioned wire stripping device may be securely fitted onto the finger by means of binding or other methods.

[0045] In this embodiment, the thumb sleeve 200 is a hollow structure with one open end and one closed end, and the index finger sleeve 400 is a hollow structure with one open end and one closed end. This protects the fingers. In other embodiments, when one of the thumb sleeve 200 and the index finger sleeve 400 is a hollow structure with one open end and one closed end, the other can be a hollow structure with openings at both ends. It is understood that in other embodiments, both the thumb sleeve 200 and the index finger sleeve 400 can also be hollow structures with openings at both ends.

[0046] In this embodiment, the open end of the thumb sleeve 200 is located at the position of the second phalanx 720 of the thumb 700. The open end of the index finger sleeve 400 is located at the position of the third phalanx 830 of the index finger 800. This makes it very convenient for the aforementioned wire stripping device to be securely fitted onto the finger. In other embodiments, when the open end of the thumb sleeve 200 is located at the position of the second phalanx 720 of the thumb 700, the open end of the index finger sleeve 400 may not be located at the position of the third phalanx 830 of the index finger 800, but rather at the junction of the second phalanx 820 and the third phalanx 830 of the index finger 800. In other embodiments, when the open end of the index finger sleeve 400 is located at the position of the third phalanx 830 of the index finger 800, the open end of the thumb sleeve 200 may also not be located at the position of the second phalanx 720 of the thumb 700, but rather at the junction of the first phalanx 710 and the second phalanx 720 of the thumb 700.

[0047] In this embodiment, the wire stripping device further includes a blade holder 600. The blade holder 600 is disposed on the thumb sleeve 200. The blade 300 is detachably connected to the blade holder 600. This facilitates the detachable connection between the blade 300 and the thumb sleeve 200, and makes it very convenient to replace the blade 300.

[0048] In this embodiment, there are multiple blades 300. The cutting edges of the multiple blades 300 are different. Thus, the above-described wire stripping device can be applied to a variety of different wires. Specifically, as... Figure 5-7 As shown, Figure 5 The blade shown is 300, which is a common type of blade, relative to... Figure 5 The blade shown is 300. Figure 6 The blade 300 shown is more suitable for wires with stiffer insulation, such as... Figure 7 The blade 300 shown is more suitable for wires with thinner and stiffer insulation.

[0049] In this embodiment, the blade holder 600 has a snap-fit. The end of the blade 300 away from the cutting edge has a fixing plate 310. The snap-fit ​​engages with the fixing plate 310. This facilitates a detachable connection between the blade 300 and the blade holder 600. In other embodiments, the blade holder 600 has a threaded hole. The end of the blade 300 away from the cutting edge has a threaded portion. The threaded portion is threadedly connected to the threaded hole.

[0050] In this embodiment, the gasket 500 includes two straight segments 520 and an arcuate segment connecting the two straight segments 520. The arcuate segment has a limiting groove 510. This makes it very convenient to form the limiting groove 510. It will be understood that in other embodiments, the two straight segments 520 may be omitted.

[0051] In this embodiment, the gasket 500 is made of metal. This not only facilitates cutting with the blade 300 but also effectively protects the index finger sleeve 400. It is understood that in other embodiments, the material of the gasket 500 is not limited to metal and can also be stone. Specifically, in this embodiment, the gasket 500 is fixed to the index finger sleeve 400 by adhesive.

[0052] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
