Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of electrician's tools, more particularly, it relates to a novel photoelectric composite wire stripping pliers. BACKGROUND

[0002] Wire stripping pliers play an important role in the field of electricians, especially for inside wire electricians, motor repairers and instrument and meter electricians, and are one of the commonly used tools. The main function is to strip the surface insulation layer of the wire head. Through ingenious design, the cut-off insulation skin and the wire can be cleanly separated, which provides a safety guarantee for electricians to a certain extent and prevents electric shock accidents.

[0003] However, it must be pointed out that the current wire stripping pliers have many obvious shortcomings in actual use. First of all, when facing some specific work requirements, the wire stripping pliers often appear to be inadequate, and other tools must be used to complete the task. For example, when 4G or 5G wire needs to be cut, it is far from enough to rely on wire stripping pliers alone, and a double-port wire pliers or a special 4G or 5G wire pliers is needed. This not only increases the number of tools to be carried and the complexity of operation, but also reduces work efficiency. Secondly, the wire stripping pliers have serious limitations when dealing with optical fiber surface coatings. Only one optical fiber surface coating can be stripped at a time, which is extremely inefficient for work scenarios that require a large number of optical fibers. Moreover, the wire stripping pliers have no spare port, and once a failure occurs or multiple tasks need to be handled simultaneously, the situation will be helpless. These shortcomings not only bring many inconveniences to electricians, but also limit the improvement of work efficiency. In summary, the existing wire stripping pliers technology indeed cannot be underestimated, and further improvement and development are needed to better meet the growing needs of the electrician industry.

Preferably, the flat side of the first fastening cap 301 and / or the second fastening cap 302 is provided with a slotted, cross-shaped, or star-shaped groove for easy tightening with a screwdriver.

[0044] The first jaw 101 and the second jaw 201 constitute two upper jaws of the wire stripping pliers, which are used to strip the insulating sheath of the outer layer of the optical fiber.

[0045] The first limiting hole 102 and the second limiting hole 202 constitute the accommodating space of the fastening unit 300, which is used to fix the top and rotate the two plier body parts.

[0046] The first handle 104 and the second handle 204 constitute two handle parts of the wire stripping pliers, which are used to hold and exert force by hands, and the positions close to the fastening unit 300 of the first handle 104 and the second handle 204 constitute two lower jaws of the wire stripping pliers, which are used to strip the insulating sheath of the outer layer of the electric wire. Preferably, the outer sides of the first handle 104 and the second handle 204 are wrapped with insulating sheath sleeves, which are used to protect and increase the friction.

[0047] Preferably, the reset spring 400 is arranged between the first elastic space 103 of the first plier body 100 and the second elastic space 203 of the second plier body 200 below the fastening unit 300. When the reset spring 400 is compressed, the distance between the jaw of the first plier body 100 and the jaw of the second plier body 200 is reduced, and when the reset spring 400 is stretched from the compressed state, the distance between the jaw of the first plier body 100 and the jaw of the second plier body 200 is increased. The first elastic space 103 and the second elastic space 203 constitute the accommodating space of the reset spring 400. Meanwhile, the first elastic space 103, the second elastic space 203 and the reset spring 400 also play a limiting role on the wire stripping pliers.

[0048] Preferably, the first limiting unit 500 and the second limiting unit 600 are arranged on the first plier body 100. The first limiting unit 500 is fixed at the third limiting hole 105, and the second limiting unit 600 is fixed at the fourth limiting hole 106. The first limiting unit 500 is used to limit the closed position and the maximum opening position of the jaws of the first plier body 100 and the second plier body 200. When the utility model is not in operation, the jaws are in the closed position, which is convenient for the storage and carrying of the wire stripping pliers. When the utility model is in operation, the maximum opening range of the upper jaw and the lower jaw is the maximum opening position, which avoids the falling and damage of the reset spring due to the overlarge opening. The second limiting unit 600 is used to limit the minimum opening position of the jaws of the first plier body 100 and the second plier body 200, that is, the opening range of the jaws when the handles are pinched tightly. Meanwhile, the second limiting unit 600 limits the caliber of each wire stripping port in the upper jaw and the lower jaw.

[0049] Specifically, as shown in FIG. 1, the first plier body 100 and the second plier body 200 are connected by the fastening unit 300, and the first handle 104 and the second handle 204 are arranged on the first plier body 100 and the second plier body 200, respectively. Figure 4As shown in the figure, the first limiting unit 500 includes a yoke 501 and a rivet 502, one side of the yoke 501 has a hole, and the other side is three-dimensionally bent. The diameter of the rivet 502 is the same as the hole diameter of the third limiting hole 105. The rivet 502 is fixed on the third limiting hole 105 through the hole of the yoke 501, and the three-dimensionally bent side of the yoke 501 can rotate around the rivet 502. The first limiting unit 500 is used to limit the closing position and the maximum opening position of the jaw of the first jaw body 100 and the second jaw body 200. When the novel photoelectric composite wire stripping pliers of the utility model is not working, the jaw is in the closing position, which is convenient for the storage and carrying of the wire stripping pliers. When the jaw is working, the maximum opening degree of the jaw is the maximum opening position, which avoids the opening being too large and the reset spring falling off and damaging the tool.

[0050] As shown in the figure, Figure 5 As shown in the figure, the second limiting unit 600 includes a specified fixed screw 601 and a clamping screw 602. The specified fixed screw 601 is fixed on the fourth limiting hole 106 of the first jaw body 100 by riveting or threaded rotation. The part of the specified fixed screw 601 protruding from the fourth limiting hole 106 is provided with a hole transversely penetrating the specified fixed screw 601. The clamping screw 602 is connected in the hole of the specified fixed screw 601 by threaded rotation. The part of the clamping screw 602 protruding from the hole of the specified fixed screw 601. The length of the part of the clamping screw 602 protruding from the hole of the specified fixed screw 601 can be adjusted by rotation. When the wire stripping pliers are pinched, one end of the clamping screw 602 protruding is tightly pressed against the second jaw body 200. Therefore, the second limiting unit 600 is used to limit the minimum opening position of the jaw of the first jaw body 100 and the second jaw body 200, that is, when the handle is pinched, the opening degree of the jaw, so as to limit the diameter of each wire stripping port in the jaw of the first jaw body 100 and the second jaw body 200. The minimum opening position can be adjusted by adjusting the clamping screw 602, so as to adjust the size of the gap between each two opposite wire stripping ports when the wire stripping pliers are working.

[0051] As shown in the figure, Figure 6 and Figure 7 As shown in the figure, the first jaw head 101 and the second jaw head 201 are provided with two upper jaws which are symmetrically arranged. The two upper jaws can be bevel jaw with acute angle or flat jaw with right angle. It is worth noting that when the upper jaw is a bevel jaw, the two upper jaws are respectively on two adjacent planes, like a pair of scissors. The smaller the angle of the bevel jaw, the easier the wire stripping operation, and the higher the damage rate of the wire stripping pliers. When the upper jaw is a flat jaw, the two upper jaws can be respectively on two adjacent planes or on the same plane.

[0052] Preferably, the two upper jaws have a symmetrical structure design, taking the upper jaw of the second jaw head 201 as an example, the upper jaw comprises a first jaw segment 710, a second jaw segment 720 and a third jaw segment 730 from top to bottom.
