[0040] In the production and processing of traditional electrical components, it is usually necessary to weld corresponding cable structures to form corresponding electrical connection paths in the product structure. Most traditional cables are in a coiled state. In the actual production process, they need to be cut into appropriate lengths in advance before they can be assembled and used on the production line. The traditional cable cutting method mostly uses manual cutting. In this cutting method, during the actual operation process, while the operator fixes the cable, the operator also needs to operate the cutting device to cut the cable. The operation process is not convenient enough, and it is difficult to complete the cutting operation of multiple cables at the same time, and it is also difficult to improve the efficiency.

[0041] The present utility model proposes a cutting device 100 to solve the above problems.

[0042] Please refer to Figures 1 to 5 , in an embodiment of the present utility model, during the process of cutting a cable, the traditional clamping and fixing structure and the cutting structure 9 are integrated. Not only is the structure more compact, but it is also convenient to fix and cut the cable. Specifically, a jaw structure 2 is provided on the base 1. Driven by the first driving member 21, two jaws 5 can be driven to rotate simultaneously on the base 1, so that the two clamping ends 511 on the two jaws 5 rotate towards each other simultaneously. When cutting the cable, when the two clamping ends 511 come into contact with each other, the cable can be fixed between the two clamping ends 511. When the extraction length of the cable meets the use requirements, the second driving member in the cutting structure 9 drives the cutter to move on one of the jaws 5, so that one end of the cutter member 91 moves towards the clamping end 511 on the other jaw 5, thereby cutting the cable between the two clamping ends 511. When cutting a plastic part, the cutting process is similar. When the plastic part is placed between the two jaws 5 and the position of the plastic part is appropriately adjusted, the plastic part can be cut by the cutter member 91. The above structure can integrate the cutting structure and the clamping structure. When cutting the cable, it can simultaneously realize the automatic fixing and cutting operations of the cable, which is more convenient than the traditional method.

[0043] Among them, in order to enable the entire device to simultaneously cut multiple cables during use, a plurality of corresponding arc-shaped clamping openings 5111 are provided on the two clamping ends 511. Rubber pads 5112 are provided on the inner arc-shaped side walls of the plurality of arc-shaped clamping openings 5111. When the corresponding two arc-shaped clamping openings 5111 are closed, the rubber pads 5112 on their inner side walls are in contact with the arc-shaped peripheral wall of the cable, thereby avoiding damaging the coating layer on the outer periphery of the cable during the hard contact with the peripheral wall of the cable. It should be noted that after the corresponding two rubber pads 5112 are in contact with the outer peripheral wall of the cable, the cable is allowed to move on its inner wall. In the actual operation process, first, the first driving member 21 drives the two jaws 5 to close simultaneously, fixing a plurality of cables between the corresponding plurality of arc-shaped clamping openings 5111. Then, one end of the cable can be pulled upward. Due to the force exerted by the rubber pad 5112, the retraction of the cable can be effectively prevented. Then, the cable is pulled upward to an appropriate length, and the second driving member drives the cutter member 91 to move in the installation groove 5113. One end of the cutter member 91 moves outward from the opening, thereby simultaneously cutting a plurality of cables between the two clamping ends 511. When one end of the cutter member 91 moves into the sinking groove 5114, it can ensure that the upper and lower ends of the plurality of cables are fully cut and separated.

[0044] It can be imagined that the radius specifications of the plurality of arc-shaped clamping openings 5111 can be set differently to adapt to a variety of different cables. At the same time, in addition to cutting cables, during the process of cutting plastic products, the plurality of arc-shaped clamping openings 5111 can effectively increase the friction force between the surface of the plastic part, thereby avoiding displacement of the plastic part during the application of force by the cutter member 91, and thus causing deformation at the cut.

[0045] The jaw 5 is specifically set as an L-shaped structure, which includes two parts: a mounting part 51 and a driving part 512. The mounting part 51 is used to perform fixing and cutting operations. The clamping end 511 and the installation groove 5113 are both provided at the position of the mounting part 51. The two driving parts 512 correspond to the first driving member 21. When the first driving member 21 works, it drives the two jaws 5 to rotate simultaneously on the base 1 by contacting the two driving parts 512. Specifically, when the two jaws 5 are installed, a convex mounting shaft 11 is provided on the upper end surface of the base 1. A collar part 5115 is provided at one end of each of the two mounting parts 51 corresponding to the base 1. The two collar parts 5115 are rotatably installed on the mounting shaft 11. During the rotation of the two jaws 5, they both rotate based on the mounting shaft 11 as the rotation basis.

[0046] In this embodiment, the first driving member 21 is arranged as a pneumatic structure. Specifically, the first driving member 21 specifically includes a first air supply device 211, a Y-shaped guiding structure 212 and two ejector rods 213. The first air supply device 211 is arranged as an air pump structure. When it supplies air, gas enters the inner cavity of the Y-shaped guiding structure 212 through the air inlet port. The air pressure in the inner cavity of the Y-shaped guiding structure 212 increases, driving the two sliding ends 2132 to slide on the inner walls of the two output ports 2121. During this process, the contact ends 2131 on the outer ends of the two sliding ends 2132 are in contact with the abutting surface 5121 on the driving part 512 and apply force to it, thereby driving the two mounting parts 51 to rotate simultaneously, so as to fix the cable or plastic part between the two clamping ends 511. On the contrary, when the first air supply device 211 sucks air, it will drive the two ejector rods 213 to retract simultaneously, so as to release the cable and plastic part by the two clamping jaws 5.

[0047] The first driving member 21 is a structural member with a rotational driving effect. In addition to the above implementation structure, it can also be arranged as a separated push rod structure. Through a rotary motor or two independent push rod members, etc., the movement effects of the above two clamping jaws 5 can be achieved. In the actual implementation process, it can be selected and used according to the existing production materials.

[0048] In order to enable the two clamping jaws 5 to automatically reset when the first air supply device 211 is in the air suction state, in this embodiment, an installation plate 3 is provided on one side of the base 1 corresponding to the separation of the two mounting parts 51, and a spring 4 is connected between the installation plate 3 and the corresponding driving part 512. When the first air supply device 211 is in the air suction state, the spring 4 performs a reset movement, which can enable the ejector rod 213 to always be in contact with the contact end 2131 during the retraction process, realizing the automatic reset of the clamping jaw 5, and at the same time making the rotational movement of the two clamping jaws 5 more stable.

[0049] In this embodiment, for cable shearing, in order to improve the convenience during the shearing process, a wire feeding structure is provided on the base 1, which can pre-fix various types of cables. During use, select the corresponding cable and cut it above the base 1. A communication port 12 is provided on the base 1 corresponding to the two clamping jaws 5, and the wire feeding structure is arranged below the base 1, which is beneficial to reducing the space occupied by the whole device and is beneficial to the overall miniaturization design of the whole device.

[0050] Specifically, a plurality of legs are provided below the base 1 to define a certain layout space below the base 1. The wire-releasing structure includes a fixed shaft 6 installed below the base 1. Two limit blocks 61 are provided on the fixed shaft 6 corresponding to the connecting port 12. The two limit blocks 61 are detachably installed on the fixed shaft 6 through threads. In actual use, the fixed shaft 6 is removed from the base 1, one of the limit blocks 61 is pre-installed, and then a plurality of winding rollers corresponding to a plurality of cables are sequentially inserted into the winding roller installation area, and then another limit block 61 is installed, so that the plurality of winding rollers are limited in the winding roller installation area, but the rotation of the plurality of winding rollers on the fixed shaft 6 is not affected. Then the entire fixed shaft 6 is installed on the base 1. During use, one end of the cable is pulled upward through the connecting port 12 to take the cable.

[0051] In this embodiment, the second driving member is configured as an air driving structure, specifically, a second air supply device 92, one end of the second air supply device 92 is connected to the air inlet 93 on the mounting groove 5113, and when the second air supply device 92 supplies and inhales air, the air pressure inside the mounting groove 5113 can be changed, thereby driving the cutting member 91 to slide on the inner wall of the mounting groove 5113.

[0052] It is conceivable that, in addition to the above configurations, the second driving member may also be configured as a push rod member or a cylinder member, etc., and may be selected and configured according to actual needs.

[0053] In order to protect the corresponding driving structure and to make it relatively isolated from the outside world, the safety of the whole device during operation is improved. In this embodiment, a first shell 7 is provided on the base 1 corresponding to the first air supply device 211 and the second air supply device 92, and a control button 71 is provided on the first shell 7 to control the start and stop of the whole fixing and shearing action. A second shell 8 is provided on the base 1 corresponding to the two driving parts 512 and the outside of the Y-shaped guide structure 212, and the corresponding structural parts are shielded by the second shell 8. An opening is provided on one end of the second shell 8 to avoid the two clamping claws 5.

[0054] A measuring tape 72 is also provided on the base 1 at a side position corresponding to one of the clamping jaws 5. In actual use, the length of the pulled cable can be measured by the measuring tape 72. The opening of the measuring tape 72 and the two clamping ends 511 are located at the same vertical height, which can improve the measurement accuracy during actual measurement.

[0055] The above is only an exemplary embodiment of the present utility model, and does not thereby limit the patent scope of the present utility model. Any equivalent structural transformation made under the technical concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields, is included within the patent protection scope of the present utility model.
