Description

Cable Strippers

technical field

The invention relates to a stripping pliers, in particular to a cable stripping pliers, belonging to the field of electric tools.

Background technique

When installing wires and circuits, electricians need to peel off the insulator of the wire end for line connection or switch connection. When connecting the line or switch connection, first peel off the insulator of the wire end, then bend the wire end, and wrap the two ends of the wire end with each other for a fixed connection. . The traditional tools for stripping cables are electrician's knife, hook knife or wallpaper knife. Because the cable sheath is very hard, during construction, construction workers often cut their hands or cut their work clothes or even cut other parts of their bodies. Bleeding incidents occur, and the cable is damaged, especially in winter construction, the cable sheath becomes hard, it is difficult to peel it off with ordinary tools, and excessive force will be more dangerous, so using such tools in the process of peeling the cable sheath Very unsafe.

The currently used wire strippers include two mutually hinged pliers handles one up and one down. A knife for stripping the cable insulation is fixed on one pliers handle, and a groove is provided on the other pliers handle corresponding to the cutting tool. for placing cables. The two pliers handles hingedly connected by the pin shaft realize the stripping of the outer insulation of the cable. The specifications of the slots for the cables on the pliers handle are fixed, but in reality the cables are thick and thin, and the different specifications limit the range of use of existing wire strippers. It is only suitable for cutting in the circumferential direction of the cable, but it is helpless for cutting the insulation in the direction of the cable length. At the same time, in some actual operations, the length of the rubber insulation that needs to be removed from each cable is consistent. This is also necessary to mark the length of the cable in advance, which is time-consuming and laborious.

Contents of the invention

The technical problem to be solved by the present invention is to provide a cable stripping pliers suitable for stripping cable insulation of various specifications, which can accurately control the stripped length of cable insulation, and is small in size and easy to carry.

In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:

Cable stripping pliers, including pliers handle Ⅰ and pliers handle Ⅱ hinged by the pin shaft at the end, horizontal knife and vertical knife are fixed on the pliers handle Ⅰ, the tip of the horizontal knife is parallel to the length direction of the pliers handle Ⅰ, and the tip of the vertical knife is in line with the pliers The length direction of the handle I is vertical, and the tips of the horizontal knife and the vertical knife both extend to between the handle I and the handle II. There are at least two cable placement slots on the handle II opposite to the tip of the horizontal knife. There is a cable placement slot on the position corresponding to the tip of the vertical knife on II, and a slide block is connected to the clamp handle II through a slideway along the length direction of the clamp handle II, and a scale is hinged on the slide block. II vertical.

A further improvement of the technical solution of the present invention lies in that: the scale is connected to the slider through a hinge.

The further improvement of the technical solution of the present invention is that: the cable placement groove is a semicircular groove that runs through the entire thickness of the pliers handle II, and there are three cable placement grooves on the pliers handle II opposite to the tip of the horizontal knife, with diameters in order 2mm, 5mm and 8mm; the diameter of the semicircular cable placement groove on the pliers handle II opposite to the tip of the vertical knife is 2mm.

The further improvement of the technical solution of the present invention is that: the length of the tip of the horizontal knife is 50mm, and the length of the tip of the vertical knife is 10mm.

Owing to having adopted above-mentioned technical scheme, the technical progress that the present invention obtains is:

Cable stripping pliers are equipped with horizontal knife and vertical knife at the same time, the tip of the horizontal knife is perpendicular to the length direction of the cable, which makes the ring cutting of the insulation in the circumferential direction simple and fast; the tip of the vertical knife is parallel to the length direction of the cable, which makes up for the The defect that the existing stripping pliers cannot vertically split the cable insulation skin expands the scope of application.

The use of the scale allows the operator to accurately control the length of the stripped cable insulation, which is suitable for occasions that require the length of insulation removal, and is more convenient to use. At the same time, the ruler is fixed on the handle of the pliers through a hinge, and the position of the ruler can be changed more flexibly. When not in use, the ruler is placed parallel to the handle of the pliers, which is convenient to carry and saves space. The cooperation of the slideway and the slider ensures that the ruler can move freely under the cable placement groove, ensuring that the length of the cable can be accurately measured by the ruler no matter where the cable is placed in any cable placement groove.

Cable slots of different diameters are provided on the handle of the pliers, which are suitable for cables of different specifications and expand the versatility of the stripping pliers.

Detailed ways

Below in conjunction with embodiment the present invention is described in further detail:

As shown in Figure 1, the cable stripping pliers include clamp handle I1 and clamp handle II2, the ends of the clamp handle I1 and clamp handle II2 are hinged into one body through a pin shaft, and the two clamp handles are hinged to realize opening and closing. There are two through slots in the length direction of the pliers handle I1, and the horizontal knife 3 and the vertical knife 4 are fixed by positioning pins in the through slots. The cutters whose length direction is parallel, the vertical cutter 4 is the cutter whose tip is perpendicular to the length direction of the pliers handle I1, the horizontal cutter 3 cutter tip length is 50mm, and the vertical cutter 4 cutter tip length is 10mm. The tips of the horizontal knife 3 and the vertical knife 4 both extend to between the pliers handle I1 and the pliers handle II2, and the pliers handle II 2 opposite to the tip of the horizontal knife 3 is provided with three cable placement slots 5, corresponding to the tip of the vertical knife 4 The pliers handle II 2 is provided with a cable placement groove 5, the cable placement groove 5 is a semicircular groove that runs through the entire thickness of the pliers handle II 2, and the diameter of the cable placement groove 5 opposite to the tip of the horizontal knife 3 is 2mm and 5mm. and 8mm; the diameter of the cable placement groove opposite to the tip of the vertical knife 4 is 2mm. Cable placement slots 5 with different diameters are arranged on the pliers handle II 2, which are suitable for cables of different specifications and expand the versatility of the stripping pliers. The horizontal knife 3 and the vertical knife 4 are installed on the cable stripping pliers at the same time. The horizontal knife 3 makes the circular cutting of the insulation in the circumferential direction simple and fast. The vertical knife 4 makes up for the defect that the existing stripping pliers cannot vertically split the cable insulation. Expand the scope of use.

A slideway 9 is arranged on the surface of the clamp handle II2 perpendicular to the plane provided with the cable placement groove 5, the slideway 9 is arranged along the length direction of the clamp handle II2, and a slide block 8 is embedded in the slideway 9, as shown in Figure 3 As shown, a scale 6 is hinged by a hinge 7 on the slide block 8 . One movable end of the hinge 7 is fixed on the slider 8, and the other end is connected with the scale 6, as shown in FIG. 4 . When it is necessary to control the stripping length of the cable, the ruler 6 can be placed parallel to the cable to be stripped. When not in use, the ruler 6 can be placed parallel to the clamp handle II 2, which is convenient to carry and saves space. The cooperation of the slideway 9 and the slide block 8 ensures that the ruler 6 can move freely below the cable placement groove 5, ensuring that the length of the cable can be accurately measured by the ruler no matter the cable is placed in any cable placement groove 5.
