BRIEF DESCRIPTION OF THE DRAWINGS
[0020] Figure 1 It is a schematic diagram of the appearance structure of the present invention.
[0021] Figure 2 It is a schematic diagram of the internal structure of the present invention. DETAILED DESCRIPTION
[0022] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following is a further detailed description in conjunction with the accompanying drawings and preferred embodiments.
[0023] See also Figure 1 and Figure 2The multifunctional electric network cable pliers of the present invention are suitable for large-scale network cable construction. The pliers include a pliers body 1 and two pliers legs 2 symmetrically hinged at the bottom of the pliers body. The pliers body 1 is provided with a crystal head fixing groove 3 and a pressing piston 4 which is guided and slidably assembled in the crystal head fixing groove. Each pliers leg is hinged to one end of a transmission rod 41, and the other ends of the two transmission rods are hinged to the bottom of the pressing piston. The hinge points of the two transmission rods and the bottom of the pressing piston are on the same axis. A reset spring 5 is provided between the two pliers legs. In the initial state, the reset spring opens the two pliers legs to Figure 1 The initial position shown is that the pressing piston is located at the bottom of the crystal head fixing groove. When crimping the network cable, put the crystal head into the crystal head fixing groove, then hold the clamp legs and bring the two clamp legs 2 close to each other, then the pressing piston is pushed upward under the action of the transmission rod, thereby realizing the pressing work of the network cable and the crystal head. After the pressing is completed, release the clamp legs 2, and the clamp legs open to the initial position under the action of the reset spring 5, and the crystal head can be taken out.
[0024] In this embodiment, the multifunctional electric network cable pliers also include an annular skin cutting device 6 and a wire unwinding device 7, wherein the annular skin cutting device includes a shell 8, a network cable fixing plate 9 and a blade 10, the shell 8 is a circular disc-shaped body, arranged parallel to the side wall of the pliers body, a double output shaft motor 11 is installed in the pliers body through a frame, a first gear 12 is provided on the right end shaft of the double output shaft motor, the first gear is engaged with a first reduction gear 14 arranged at the left end of the hollow shaft 13, the hollow shaft 13 is rotatably installed on the right shell of the pliers body through a bearing, the right end of the hollow shaft passes through the pliers body and is connected to the shell 8, the blade 10 is embedded in the shell, and the network cable fixing plate 9 is arranged parallel to the side wall of the pliers body. The fixed plate 9 is slidably installed in the shell and is located on the opposite side of the blade. A net cable fixing groove 12 is provided on the net cable fixing plate, and the net cable fixing groove cooperates with the blade to position the net cable; the first pull ring 15 passes through the shell and is connected to the net cable fixing plate 9, and the upper and lower ends of the net cable fixing plate are respectively connected one by one with the columnar bodies 16 that are guided and slidably installed on the upper and lower ends of the shell. An adjustment hole 17 is opened in the semicircular area of the shell on one side of the blade. After the screw is threadedly connected to the adjustment hole 17, one end of the tension spring 18 can be fixed, and the other end of the tension spring 18 is hung with the columnar body 16. Therefore, under the tension of the tension spring, the net cable fixing groove can press the net cable onto the blade. Furthermore, a through transparent hole 19 is provided in the clamp body, and the right end of the transparent hole is connected with the left end outlet of the hollow shaft 13 without contact between the two. The network cable passes through the hollow tube and enters the transparent hole. A length mark 20 is engraved on the transparent hole, and the shell of the clamp body is also designed to be transparent at the corresponding position of the transparent hole, so that the operator can observe the depth of the network cable, so as to cut off the specified length of the network cable skin. The connection relationship between the transparent hole and the hollow shaft can adopt at least the following two schemes: 1. There is a gap between the right end of the transparent hole and the left end outlet of the hollow shaft, and the transparent hole and the hollow shaft are concentrically arranged; 2. The outer diameter of the hollow shaft is smaller than the inner diameter of the transparent hole, so that the left end of the hollow shaft can enter the transparent hole for a short distance, and the transparent hole and the hollow shaft are concentrically arranged.
[0025] Since the thickness and toughness of the outer sheath of network cables of different batches and models are different, in order to adjust the cutting force, a plurality of adjustment holes are provided on the semicircular area on one side of the blade along the direction from the network cable fixing plate to the blade. By selecting a screw and installing it into a certain adjustment hole to press the tension spring, the clamping force of the network cable fixing plate and the blade on the network cable can be adjusted. Before large-scale cutting, the strength of the tension spring can be adjusted and large-scale cutting work can be carried out. When cutting the skin, pull up the first pull ring 15, then insert the mesh cable into the mesh cable fixing groove and then into the hollow shaft. The inner diameter of the hollow shaft is larger than the diameter of the mesh cable. In this embodiment, the inner diameter of the hollow shaft is 8mm-10mm. Then, after determining the cutting length, loosen the first pull ring to fix the mesh cable, start the dual output shaft motor to drive the first reduction gear 14 to operate, and the hollow shaft drives the annular skin cutting device 6 to rotate. When the mesh cable is held in hand, the outer skin of the mesh cable is easily cut off under the rotating ring cutting of the blade. Pull out the mesh cable to the right, and the cut outer skin will naturally fall off the clamp body from the left end of the transparent hole, thus completing the first stage of mesh cable production.
[0026] The unwinding device is used to unwind the wound wire group, which includes a rotating barrel 21, a second pull ring 22, a fixed magnet 23 and a moving magnet 24, wherein the second pull ring 22 passes through the rotating barrel 21 and is connected to the moving magnet 24, the fixed magnet 23 is fixed in the rotating barrel and arranged opposite to the moving magnet, one end of the rotating barrel is open, and the other end is fixed to one end of the rotating drum shaft 25, and the other end of the rotating drum shaft 25 is connected to the second reduction gear 26, and the second reduction gear is meshed with the second gear 27 arranged on the left end shaft of the dual output shaft motor. The control end of the dual output shaft motor is electrically connected to the forward button 28 and the reverse button 29, and the forward button and the reverse button are both arranged on the clamp body for manual pressing.
[0027] When unwinding the wires, pull the second pull ring to pull up the upper moving magnet and separate it from the lower fixed magnet, then put the two wound data wires between the two magnets, release the pull ring, and the two magnets clamp the head of the wire group, turn on the forward or reverse button to unwind the two data wires, and complete the second stage of network cable production. Then send the arranged wires into the crystal head for pressing to complete the network cable production.
[0028] It is worth mentioning that the rotation speeds of the annular skin cutting device and the wire unwinding device in the present invention are both relatively low. For example, the annular skin cutting device can generally cut off the outer skin of the network cable A by rotating about three circles, and the wire unwinding device can complete rapid wire unwinding at a speed of two to three revolutions per second. The first and second reduction gears increase the rotational force of each device while reducing the rotation speed, thereby achieving the purpose of low speed and high torque, which is very suitable for the application scenario of the present invention.
[0029] In addition, the purpose of setting the two buttons, the forward button and the reverse button, is that the network cable manufacturer divides the braiding into two situations, clockwise braiding and counterclockwise braiding, so when unwinding the cable in the reverse direction, the present invention provides two-way unwinding functions to prevent different manufacturers from having different production standards. When unwinding the cable, if the network cable is purchased from the same manufacturer, then the braiding direction is theoretically unified, so when unwinding the batch of network cables, it is sufficient to determine whether to use forward or reverse rotation to unwind, and then large-scale construction can be carried out.
[0030] Preferably, the present invention also integrates a wire cutting device, which includes a wire cutting blade 30 and a wire groove 31. The wire cutting blade is arranged on one of the pliers legs, and the wire groove is arranged at a corresponding position of the other pliers leg. In order to prevent the wire cutting blade from cutting the operator, a protective cover 32 is arranged on the outside of the blade.
[0031] As a preferred embodiment, the present invention is further provided with a wire-punching device, which includes a wire-punching knife 33 and a push spring 34 arranged inside the pliers legs. Both pliers legs are hollow structures. The push spring is connected to the tail of the wire-punching knife. A spring pin 35 is provided on the wire-punching knife. A pin hole 36 cooperating with the spring pin is provided on the pliers legs. A push-pull slide cover 37 is provided at the bottom of the pliers legs. When using the wire-punching knife, the push-pull slide cover is opened, the wire-punching knife pops out under the action of the push spring, and then the head of the wire-punching knife is pulled outward by hand and the spring pin falls into the pin hole to realize the positioning of the wire-punching knife; when it needs to be folded, the spring pin is pressed down to disengage it from the pin hole, and then the wire-punching knife is pushed into the pliers legs and the push-pull slide cover is closed.
[0032] Preferably, the rod portion on the first pull ring connected to the network cable fixing plate is slidably connected to the outer shell through a sleeve embedded in the outer shell to prevent the pull ring from shaking and making abnormal noise during the rotation of the annular skin cutting device; similarly, the second pull ring is also limited by the sleeve, which will not be elaborated.
[0033] In this embodiment, a battery for powering the dual output shaft motor is arranged in the right caliper leg. The battery is preferably a small lithium battery. The caliper leg is also provided with a charging port 38 for charging the battery and an indicator light 39 for displaying the remaining battery power.
[0034] The above is only a preferred embodiment of the present invention. Any technician familiar with the profession, without departing from the scope of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention, still falls within the scope of the technical solution of the present invention.
