Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

A cable cutter comprises a cutter frame 1, wherein a fixed cutter head 12 is fixedly connected to one side of the cutter frame 1, two driving arms 2 are arranged on one side, away from the fixed cutter head 12, of the cutter frame 1, one driving arm 2 is fixedly connected with the cutter frame 1 and arranged at the bottom of the joint of the fixed cutter head 12 and the cutter frame 1, and the end part of the other driving arm 2 is arranged in the cutter frame 1 and is rotatably connected with the cutter frame 1. The tail end of the fixed cutter head 12 is hinged with an active cutter head 11, the outer contour of the active cutter head 11 is arc-shaped, teeth are uniformly distributed along the outer contour, when the outer contour of the active cutter head 11 rotates into the cutter frame 1, the active cutter head 11 and the fixed cutter head 12 form a closed cutter edge, the end part of the driving arm 2 which is rotatably connected with the cutter frame 1 is provided with a transmission mechanism 13 which is matched with the teeth and drives the active cutter head 11 and the fixed cutter head 12 to rotate relatively, and therefore the closed cutter edge cuts the cable. The transmission mechanism 13 is prior art in the field of cable shears and will not be described in detail here.

As shown in fig. 1 and 2, the driving arm 2 includes an insertion rod 22 and a sleeve 21 disposed on an outer peripheral surface of the insertion rod 22, and the sleeve 21 is slidably connected to the insertion rod 22 along a length direction of the insertion rod 22. One of the insertion rods 22 has its end fixed in the tool holder 1, and the other insertion rod 22 has its end rotatably connected in the tool holder 1 and connected to the transmission mechanism 13. The inner peripheral surface of sleeve pipe 21 has the fixed ring 211 of a plurality of (fixed ring 211 sets up to four in this embodiment) along the coaxial rigid coupling of the length direction of sleeve pipe 21, and adjacent fixed ring 211 interval sets up, and the inner peripheral surface of fixed ring 211 is seted up there is the internal thread, and the one end coaxial rigid coupling that keeps away from knife rest 1 corresponding inserted bar 22 has a cylindrical fixed block 221, and the outer peripheral surface of fixed block 221 is seted up and is fixed the internal thread external screw thread that mutually supports with fixed ring 211.

When the staff is using the cable to cut the cable conductor, if meet the diameter thick or during the hard cable of texture, the staff can control the sliding of inserted bar 22 in sleeve pipe 21, and then the whole length of adjustment actuating arm 2, and make mutual rotation between inserted bar 22 and the sleeve pipe 21, advance fixed ring 211 that corresponds with fixed block 221 screw in, thereby realized the regulation and the fixing of the whole length of actuating arm 2, through the physical demands of the mode that increases the arm of force in order to save staff's shearing. The arrangement of the fixing rings 211 enables the driving arm 2 to be adjusted in multiple lengths, so that the whole length of the driving arm 2 can be adjusted conveniently by a worker according to actual conditions, and the purpose of saving labor is achieved.

As shown in fig. 2, a stop ring 212 is fixed to the end of the sleeve 21 facing the tool holder 1, and the inner peripheral surface of the stop ring 212 abuts against the outer arm of the insert rod 22. When the fixing block 221 slides to the port of the sleeve 21, the limiting ring 212 and the fixing block 221 contact with each other, so that the insertion rod 22 is limited from being separated from the sleeve 21, and the stability of the cable cutter in use is improved. Both end surfaces of the fixing block 221 are respectively provided with a chamfer which is convenient for the fixing block 221 to slide into the fixing ring 211. When the fixing block 221 slides to a position corresponding to the fixing ring 211, the cut angle formed by the fixing block 221 guides the fixing block 221 and guides the end of the fixing block 221 into the fixing ring 211, so that accuracy of screwing the fixing block 221 and the fixing ring 211 is improved, and difficulty in butt joint of the fixing block 221 and the fixing ring 211 is reduced.

When a worker is cutting thick cables, as shown in fig. 3 and 4, the worker often places the driving arm 2 fixedly connected to the tool post 1 on the ground and cuts the cables by vertically pressing down the other driving arm 2. However, in the actual use process, since the contact area between the driving arm 2 and the ground is small, it is difficult to stably place the driving arm, and when a worker presses down another driving arm 2, the cable cutter may be entirely toppled, which is inconvenient for the cutting work. In order to solve the problem, a connecting rod 31 is vertically and fixedly connected to the side wall of the tool rest 1 far away from the driving arm 2 rotationally connected with the tool rest 1, one end of the connecting rod 31 far away from the tool rest 1 is rotationally connected with a supporting seat 3, and the supporting seat 3 is perpendicular to the rotating shaft of the connecting rod 31 and the plane where the axes of the two driving arms 2 are located. When supporting seat 3 can place on ground, increased the area of contact of cable scissors with ground, strengthened the stability of cable scissors side when standing on ground.

As shown in fig. 3 and 4, the driving arm 2 on the same side of the supporting seat 3 is further provided with a placing plate 4 for assisting in supporting the supporting seat 3, the placing plate 4 is located on one side of the sleeve 21 facing the supporting seat 3 and is rotatably connected with the sleeve 21, the placing plate 4 is parallel to the supporting surface of the supporting seat 3, and the rotating shafts of the placing plate 4 and the sleeve 21 are parallel to the connecting rod 31. When the cable is cut the side and is stood on ground, the staff can rotate and place board 4, makes the length direction of placing board 4 and actuating arm 2 mutually perpendicular to improve the base area on actuating arm 2 and ground, improved the stability that the cable was cut and was established. When the cable scissors are operated by hands, the length direction of the placing plate 4 is rotated to be parallel to the length direction of the driving arm 2, so that the occupied space of the placing plate 4 is reduced, and the cable scissors are convenient for the handheld operation of workers.

The working process is as follows: when the staff uses the cable to cut the cable conductor, can put into the cable conductor between initiative tool bit 11 and the fixed tool bit 12, then press and move two actuating arms 2, make interlock each other between initiative tool bit 11 and the fixed tool bit 12, and then cut the cable wire, if meet the cable wire thick, the condition that the inner core is harder, the staff can control sleeve pipe 21 and inserted bar 22 and slide, and with sleeve pipe 21 and inserted bar 22 rotation each other, make fixed block 221 threaded connection advance solid fixed ring 211 in, thereby adjust and fix the whole length of actuating arm 2. The staff can also place board 4 rotatory to with sleeve pipe 21 mutually perpendicular to will place board 4 and supporting seat 3 and place subaerial simultaneously, the vertical actuating arm 2 that pushes down and be located the top this moment, thereby cut the cable cutter.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
