A wiring notch is vertically formed in the center of the detection table 1 and penetrates the surface of the detection table 1, and a pull wire sliding groove 11 is symmetrically arranged in the wiring notch along the length direction of the detection table 1; a scale 12 is arranged along the length direction of the detection table 1 at the edge of the top surface of the detection table 1. The first clamping mechanism 2 comprises a plurality of front end clamping assemblies, and the second clamping mechanism comprises a plurality of rear end clamping assemblies, and the plurality of front end clamping assemblies correspond one-to-one to the plurality of rear end clamping assemblies. The second clamping mechanism 3 slides on the detection table 1 through a pulley arranged in the pull wire sliding groove 11 and straightens a plurality of mobile phone charging wire materials clamped between the first clamping mechanism 2 and the second clamping mechanism 3, and the length of the charging wire material to be cut is obtained through the measurement pointers arranged on the first clamping mechanism 2 and the second clamping mechanism 3 respectively, and the plurality of mobile phone charging wire materials are cut in alignment by the cutting tool 9.

[0038] The first clamping mechanism 2 comprises a front end fixed plate 21 fixedly arranged on the detection table 1, the front end fixed plate 21 being located at one side of the wiring notch, a plurality of front end clamping assemblies being arranged side by side on the front end fixed plate 21, each front end clamping assembly comprising a fixed first clamping block 22 and a movable second clamping block 23. Each second clamping block 23 is provided with a sliding rail matched with a sliding groove, so that each second clamping block 23 can slide relative to the first clamping block 22 on the front end fixed plate 21, and thus each first clamping block 22 and the corresponding second clamping block 23 can be separated or folded, and the first clamping block 22 and the second clamping block 23 can clamp the front end of the mobile phone charging wire material to be processed when they are folded.

[0039] Further, a half clamping groove is formed on the side of the first clamping block 22 facing the second clamping block 23, and a half clamping groove is also formed on the side of the second clamping block 23 facing the first clamping block 22, the half clamping groove on the first clamping block 22 is opposite to the half clamping groove on the second clamping block 23, so that the first clamping block 22 and the second clamping block 23 are folded to form an oval front end clamping groove 24 for clamping the front end of the charging wire.

[0040] Further, the first clamping block 22 and the second clamping block 23 are connected by a first reset spring 25, so that the first clamping block 22 and the second clamping block 23 remain in the folded state in the initial state, and the first clamping block 22 and the second clamping block 23 can clamp the front end of the charging wire inserted into the front end clamping groove 24 in the folded state, when subjected to external force, the second clamping block 23 slides on the slide rail, so that the second clamping block 23 is separated from the first clamping block 22, at this time, the front end clamping groove 24 is opened and the mobile phone charging wire in the front end clamping groove 24 is released.

[0041] Further, a first measuring pointer 26 is fixedly arranged on the front end face of the front end fixed plate 21, the first measuring pointer 26 points to the starting scale on the scale 12.

[0042] Further, a first pressing assembly 27 is arranged on each front end clamping assembly, the first pressing assembly 27 includes an S-shaped elastic sheet 271 and a lever 272; the S-shaped elastic sheet 271 is arranged horizontally and fixed on the top of the first clamping block 22; the lever 272 is fixed on the second clamping block 23 through a connecting block and extends above the top surface of the first clamping block 22, and the lever 272 is located inside the wave crest of the S-shaped elastic sheet 271 in the initial state. In the initial state of the folded first clamping block 22 and the second clamping block 23, the S-shaped elastic sheet 271 is pressed against the charging wire inserted into the front end clamping groove 24 under the elastic action; when the second clamping block 23 is separated from the first clamping block 22 under external force, the lever 272 on the second clamping block 23 follows the second clamping block 23 away from the first clamping block 22, at this time, the lever 272 will resist and gradually lift the S-shaped elastic sheet 271, so that the S-shaped elastic sheet 271 releases the charging wire in the front end clamping groove 24, so that the charging wire is inserted or pulled out of the front end clamping groove 24. The actual use scene is that when the second clamping block 23 is separated from the first clamping block 22 under external force, the front end clamping groove 24 is opened and the S-shaped elastic sheet 271 is lifted, so that it is easy to insert the charging wire into the front end clamping groove 24, and when the second clamping block 23 is separated from the first clamping block 22 again, the charging wire is easily pulled out of the front end clamping groove 24.

[0043] The second clamping mechanism 3 comprises a rear end sliding plate 31 movably arranged on the wiring slot, and a plurality of rear end clamping assemblies are arranged side by side on the rear end sliding plate 31, each of the rear end clamping assemblies comprises a fixed third clamping block 32 and a movable fourth clamping block 33. Each of the fourth clamping blocks 33 is provided with a sliding rail and a sliding groove matched with each other, so that each of the fourth clamping blocks 33 can slide relative to the third clamping block 32 on the rear end fixed plate, and thus each of the third clamping block 32 and the corresponding fourth clamping block 33 can be separated or folded, and the third clamping block 32 and the fourth clamping block 33 can clamp the rear end of the mobile phone charging wire rod to be processed when being folded.

[0044] Further, a half clamping slot is formed on the side of the third clamping block 32 facing the fourth clamping block 33, and a half clamping slot is also formed on the side of the fourth clamping block 33 facing the third clamping block 32, the half clamping slot on the third clamping block 32 is opposite to the half clamping slot on the fourth clamping block 33, so that the third clamping block 32 and the fourth clamping block 33 form an oval rear end clamping slot 34 for clamping the charging wire rod after being folded, and the rear end clamping slot 34 penetrates the rear end clamping assembly left and right, so that the rear end clamping slot 34 can clamp the rear end of the charging wire rod like a clamp.

[0045] Further, the third clamping block 32 and the fourth clamping block 33 are connected by a second reset spring 35, so that the third clamping block 32 and the fourth clamping block 33 remain in the folded state in the initial state, and the third clamping block 32 and the fourth clamping block 33 can clamp the charging wire rod in the rear end clamping slot 34 in the folded state, when an external force is applied, the fourth clamping block 33 slides on the sliding rail, so that the fourth clamping block 33 is separated from the third clamping block 32, at this time, the rear end clamping slot 34 is opened and the charging wire rod in the rear end clamping slot 34 can be released.

[0046] Further, in the embodiment, the reset elastic force of the second reset spring 35 is smaller than the elastic force of the first reset spring 25, so that the first clamping assembly can "clamp" the front end of the charging wire rod, and the second clamping assembly only "clamps" the rear end of the charging wire rod, so that after the front end of the charging wire rod is aligned and clamped, the rear end of the charging wire rod in the rear end clamping assembly (not necessarily aligned) is still in an adjustable state, and after the charging wire rod between the first clamping assembly and the second clamping assembly is adjusted, the length of the charging wire rod remains consistent, which is more conducive to one-time batch cutting of the charging wire rod.

[0047] Further, a second measurement pointer 36 is fixedly arranged on the front end surface of the rear end sliding plate 31, and the second measurement pointer 36 points to the scale on the scale 12.

[0048] Further, in order to control each fourth clamping block 33 in the rear clamping assembly to separate synchronously with the corresponding third clamping block 32, the second clamping mechanism further comprises a 7-shaped operating rod 37 rotatably connected to each fourth clamping block 33. Specifically, the side surface of each fourth clamping block 33 is provided with an extension plate, and a mounting hole is coaxially arranged on each extension plate. The operating rod 37 is rotatably mounted in the mounting holes of all fourth clamping blocks 33. When the operating rod 37 is pulled manually, each fourth clamping block 33 is driven by the operating rod 37 to separate from the corresponding third clamping block 32. The opening and closing of each rear clamping assembly can be controlled synchronously by one operating rod 37. At the same time, when the operating rod 37 is rotated, the bent part of the operating rod 37 can be clamped on the front side edge of the detection table 1, so that each fourth clamping block 33 and the corresponding third clamping block 32 are kept in a separated state, facilitating the loading and unloading of the charging wire.

[0049] Further, in order to improve the automation degree of the device, a third return spring 38 is further connected to the rear sliding block. One end of the third return spring 38 is fixed to the rear sliding block, and the other end is fixed to the detection table 1. After a plurality of charging wire materials for mobile phones are all loaded onto the detection table 1, the rear sliding plate 31 gradually moves away from the front fixed plate 21 due to the action of the third return spring 38, so that the charging wire material in the originally curved and relaxed state is straightened and tightened, which is more conducive to cutting the charging wire material with consistent length.

[0050] Further, in order to improve the sliding stability of the rear sliding plate 31, a pair of pulleys 39 are further arranged at the bottom of the rear sliding plate 31. The pulleys 39 cooperate with the pull line sliding groove 11 on the detection table 1 to limit the rear sliding plate 31, and make the rear sliding plate 31 slide more smoothly on the detection table 1.

[0051] Please refer to Figure 2 , the pedal control mechanism 4 comprises a first pedal 41, a first traction cable 42, a second pedal 43 and a second traction cable 44.

[0052] One end of the first traction cable 42 is connected to the first pedal 41, and the other end is connected to each second clamping block 23 through a change direction pulley 45 fixed on the detection table 1. When the first pedal 41 is stepped down with the foot, each second clamping block 23 is driven by the first traction cable 42 to separate from the corresponding first clamping block 22. When the first pedal 41 is released, each second clamping block 23 and the corresponding first clamping block 22 are folded due to the action of the first return spring 25. Thus, the opening and closing of all front clamping assemblies can be controlled synchronously by the first pedal.

[0053] The second traction cable 44 is connected to the second pedal 43 at one end and to the limiting spring pin 46 arranged on the detection table 1 at the other end. When the second pedal 43 is stepped down, the second traction cable 44 retracts the limiting spring pin 46 to the top surface of the detection table 1, so that the rear end sliding plate 31 can slide to the direction of the front end fixed plate 21; when the second pedal 43 is released, the limiting spring pin 46 is reset and extends above the top surface of the detection table 1, and the limiting spring pin 46 limits the rear end sliding plate 31.

[0054] The cutting tool 9 is hinged on the rear end sliding plate, and the handle at one end of the cutting tool 9 can be pulled to batch cut a plurality of charging wire lines located between the first clamping mechanism 2 and the second clamping mechanism 3.

[0055] Further, in order to enhance the adaptability of the device, the mobile phone charging wire length batch cutting device also comprises a wire length adjusting assembly 5, which comprises a group of equidistantly arranged adjusting screw holes 51 on the side surface of the detection table, and a right-angled bent adjusting plate 52, a through hole is arranged on the adjusting plate 52, and a pin is arranged in the through hole. The pin cooperates with any adjusting screw hole 51 to fix the adjusting plate 52 on the detection table, the adjusting plate 52 limits the sliding stroke of the rear end sliding plate, so that the length of the charging wire line to be cut can be adjusted, and the adaptability is improved.

[0056] Further, as a preferred embodiment, the inner surfaces of the front end clamping groove 24 and the rear end clamping groove 34 are provided with a layer of elastic soft pad, so as to avoid damage to the charging wire line caused by hard contact of the hard surface with the charging wire line, and to facilitate the quality of the charging wire line after measurement.

[0057] The working process of the mobile phone charging wire length batch cutting device is as follows:

[0058] 1) Adjust the position of the adjusting plate 52 in the wire length adjusting assembly 5 to the appropriate length according to the actual length to be cut;

[0059] 2) Step on the first pedal 41, each second clamping block 23 is separated from the corresponding first clamping block 22, and the S-shaped elastic sheet of each first pressing assembly 27 is lifted by the lever, and the user inserts the front end of the charging wire line into the front end clamping groove 24;

[0060] 3) Release the first pedal 41, the first spring is reset, each second clamping block 23 and the S-shaped elastic sheet of each first pressing assembly 27 are reset, and the front end of each charging wire line is clamped and pressed;

[0061] 4) Step down the second pedal 43, the limit spring pin 46 sinks, manually push the rear end sliding plate 31 to the position close to the front end fixed plate 21, and release the second pedal 43 so that the limit spring pin 46 limits the rear end sliding plate 31, so that the rear end sliding plate 31 remains close to the front end fixed plate 21;

[0062] 5) Turn the control lever 37 to the rear, and the bending part of the control lever 37 is clamped on the front side of the detection table, the control lever 37 drives each fourth clamping block 33, so that each fourth clamping block 33 is separated from the corresponding third clamping block 32, the user clamps the rear end of the charging wire into the rear end clamping slot 34, and then releases the control lever 37, and the second spring resets, each rear end clamping assembly is folded, and the rear end of the charging wire is clamped;

[0063] 6) Step down the second pedal 43 again, and the limit of the limit spring pin 46 to the rear end sliding plate 31 is eliminated, and under the action of the third reset spring 38, the rear end sliding plate 31 slowly moves away from the front end fixed plate 21 until it is limited by the adjusting plate 52 in the wire length adjusting assembly 5 (since the rear end clamping assembly only clamps the charging wire, but does not clamp the wire, in this process, the charging wire transmission wire is straightened and tightened);

[0064] 7) Check the length of the charging wire to be cut through the second measuring pointer 36 on the rear end sliding plate 31;

[0065] 8) Batch cut a plurality of charging wires through the cutting tool 9.

[0066] 9) The process of unloading the cut charging wire from the detection table 1 is opposite to the loading process of steps 1 to 6.

[0067] Compared with the prior art, the beneficial effects of the present application are that the mobile phone charging wire length batch cutting device can simultaneously batch cut a plurality of mobile phone charging wires with the same length, has high precision and high efficiency. The wire length adjusting assembly 5 is arranged to limit the rear end sliding block before cutting, so that the device can be used to cut charging wires of different lengths, and has good adaptability.
