[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Reference Figures 1-3 The present invention provides an embodiment of a shielded cable laying and cutting device, comprising an L-shaped workbench 1. The L-shaped workbench 1 is mainly used as a functional operating platform for laying and cutting cables. A laying reel 2 is provided on the upper surface of the L-shaped workbench 1. The laying reel 2 is used to store the shielded cable. A conveying roller 3 is provided on the upper side wall of the L-shaped workbench 1. The conveying roller 3 can convey the shielded cable to the cutting mechanism. A cutting mechanism 4 is provided on the upper surface of the L-shaped workbench 1.

[0036] Reference Figure 1 and Figures 3-4The thread cutting mechanism 4 includes a motor 41. The output shaft of the motor 41 is fixedly connected to a connecting rod 42. The output shaft of the motor 41 drives the connecting rod 42 to rotate around a center. The end of the connecting rod 42 away from the output shaft of the motor 41 contacts a pressing block 43. A circular block is provided on the surface of the end of the connecting rod 42 away from the output shaft of the motor 41. The rotation of the connecting rod 42 around the center will cause the circular block on the surface to rotate and slide in the groove on the right side of the pressing block 43, and at the same time, it will cause the pressing block 43 to move up and down on the surface of the L-shaped worktable 1. The L-shaped worktable 1 has a sliding groove on its side wall, and a protrusion is provided on the back of the pressing block 43. The protrusion of the pressing block 43 is slidably connected in the sliding groove of the L-shaped worktable 1. The sliding groove on the side wall of the L-shaped worktable 1 serves as a guide, ensuring that the protrusion on the back of the pressing block 43 can only slide back and forth within the sliding groove. A fixed seat 44 is fixedly connected to the upper side wall of the L-shaped worktable 1. A telescopic rod 45 is hinged to the outer side wall of the fixed seat 44. The end of the telescopic rod 45 away from the fixed seat 44 is hinged to a... Push block 46, one end of telescopic rod 45 is hinged to the outer side wall of fixed base 44, and the other end of telescopic rod 45 is hinged to the side wall of push block 46. When the shielded cable contacts telescopic rod 45, it applies a pushing force to telescopic rod 45, causing telescopic rod 45 to rotate and swing in the opposite direction, pushing push block 46 to move to the right. The side wall of L-shaped workbench 1 is provided with a sliding groove, and the back of push block 46 is provided with a protrusion. The protrusion on the back of push block 46 is slidably connected in the sliding groove of L-shaped workbench 1. The sliding groove on the side wall of the worktable 1 serves as a guide, allowing the protrusion on the back of the push block 46 to slide back and forth within the groove. The right side of the push block 46 contacts the rotating block 47. As the push block 46 moves to the right, it drives the rotating block 47 to rotate in the opposite direction until it aligns with the upper surface of the cutter 410. When the pressing block 43 slides downward under the drive of the motor 41, it applies a downward force to the rotating block 47. The rotating block 47 then applies a downward force to the cutter 410, achieving the effect of cutting the shielded cable.

[0037] Reference Figures 5-7The rotating block 47 is elastically connected to the rotating seat 48 via a spiral spring 49. One end of the spiral spring 49 is fixedly connected to the lower surface of the rotating block 47, and the other end is fixedly connected to the surface of the rotating seat 48. The spiral spring 49 is used to automatically reset the rotating block 47 after it has moved. The side wall of the L-shaped worktable 1 is provided with a sliding groove, and the top side wall of the cutting blade 410 is provided with a protrusion. The protrusion on the top of the cutting blade 410 is slidably connected to the sliding groove of the L-shaped worktable 1. The sliding groove on the side wall of the L-shaped worktable 1 serves as a guide, so that the protrusion on the top of the cutting blade 410 can only slide back and forth within the sliding groove. The upper surface of the L-shaped worktable 1 is fixedly connected to the connecting seat 412, and the lower surface of the connecting seat 412 is fixedly connected to the upper end surface of the L-shaped worktable 1. The inner wall of the rotating block 47... The rotating block 47 is slidably connected to the outer wall of the rotating seat 48, which supports the rotating block 47 so that the rotating block 47 can only rotate and slide on the surface of the rotating seat 48. The rotating seat 48 is fixedly connected to the upper surface of the L-shaped worktable 1. The connecting rod 42 is rotatably connected to the front surface of the L-shaped worktable 1, which supports the connecting rod 42 so that the connecting rod 42 can only rotate around the center along the side wall of the L-shaped worktable 1. The connecting seat 412 is elastically connected to the cutting blade 410 through the spring 411. One end of the spring 411 is fixedly connected to the lower surface of the pressing end of the cutting blade 410, and the other end of the spring 411 is fixedly connected to the upper surface of the connecting seat 412. The function of the spring 411 is to reset the cutting blade 410 after it is squeezed. The upper side wall of the L-shaped worktable 1 is provided with a clamping mechanism 5.

[0038] Reference Figures 1-2 and Figure 4 The clamping mechanism 5 includes a pulley 51. The output shaft of the motor 41 passes through and is fixedly connected to the rotation center shaft of the pulley 51. The motor 41 drives the pulley 51 to rotate around the center through the output shaft. The rotating wheel 53 is rotatably connected to the side wall of the L-shaped worktable 1. The L-shaped worktable 1 supports the rotating wheel 53. The pulley 51 is connected to the rotating wheel 53 via a transmission belt 52. The rotation of the pulley 51 drives the transmission belt 52 to rotate, and the transmission belt 52 drives the rotating wheel 53 to rotate around the center. The surface of the rotating wheel 53 contacts a hinge rod 54. The rotation of the rotating wheel 53 around the center drives the circular block on its surface to rotate around the center, thus driving the rotating wheel 53 to rotate. The circular block on the surface of the rotating wheel 53 rotates and slides within the groove on the surface of the hinge rod 54, causing the hinge rod 54 to swing up and down. The hinge rod 54 is rotatably connected to the surface of the rear end of the L-shaped worktable 1. The L-shaped worktable 1 is fixedly hinged to one end of the hinge rod 54, allowing the hinge rod 54 to swing up and down as the rotating wheel 53 rotates. A slider 57 is slidably connected to the right side of the hinge rod 54. The left and right sliding of the slider 57 causes the hinge rod 54 to swing up and down. An upper fixing clamp 55 is slidably connected to the surface of the slider 57. The left and right sliding of the slider 57 causes the hinge rod 54 to swing up and down, and the up and down swing of the hinge rod 54 causes the upper fixing clamp 55 to slide up and down.

[0039] Reference Figures 1-2 and Figure 4 The L-shaped workbench 1 has a sliding groove on its side wall, and the upper fixing clamp 55 has a trapezoidal protrusion on its side wall. The trapezoidal protrusion on the side wall of the upper fixing clamp 55 is slidably connected to the sliding groove of the L-shaped workbench 1. The sliding groove on the side wall of the L-shaped workbench 1 serves as a guide, allowing the trapezoidal protrusion on the side wall of the upper fixing clamp 55 to slide back and forth only within the sliding groove. The side wall of the L-shaped workbench 1 has a cavity, and the rear end of the upper fixing clamp 55 has a notch. The rear end of the upper fixing clamp 55 passes through and is slidably connected to the cavity on the side wall of the L-shaped workbench 1. The cavity on the side wall of the L-shaped workbench 1 serves as a guide and fixation, allowing the upper fixing clamp 55 to slide back and forth only within the cavity, thus achieving the effect of reciprocating fixation of the shielded cable. The upper side wall of the L-shaped workbench 1 is fixedly connected to the lower fixing clamp 56. The lower fixing clamp 56 is fixedly connected to the L-shaped workbench 1, and the shielded cable is fixed by the up and down movement of the upper fixing clamp 55.

[0040] Working principle: When using this equipment, motor 41 drives connecting rod 42 to rotate around the center. The rotation of connecting rod 42 around the center causes pressing block 43 to slide up and down reciprocally. The shielded cable is fed into conveying roller 3 through unwinding reel 2. Conveying roller 3 conveys the shielded cable to wire cutting mechanism 4. The cable is then conveyed to the actuating end of telescopic rod 45. The shielded cable applies a pushing force to the actuating block at the bottom of telescopic rod 45, pushing the other end of telescopic rod 45 to rotate in the opposite direction. The opposite rotation of the other end of telescopic rod 45 pushes push block 46 to slide to the right. Sliding to the right will push the rotating block 47 to rotate to the right. When the rotating block 47 rotates to the surface of the pressing end of the cutter 410, the pressing block 43 will squeeze the rotating block 47, causing the rotating block 47 to slide downward. The downward sliding of the rotating block 47 will drive the cutter 410 to slide downward, achieving the effect of cutting the shielded cable. After the cutting is completed, the pressing block 43 will slide upward driven by the motor 41. The rotating block 47 will be automatically reset by the spiral spring 49, and the cutter 410 will be automatically reset by the spring 411. With this wire cutting mechanism 4, shielded cables can be cut to the same length without manual intervention.

[0041] The lower fixing clamp 56 is fixedly connected to the side wall of the L-shaped workbench 1. The output shaft of the motor 41 drives the pulley 51 to rotate. The pulley 51 drives the rotating wheel 53 to rotate through the transmission belt 52. The rotating wheel 53 rotates around the center and drives the hinge rod 54 to slide up and down. While the hinge rod 54 slides up and down, the slider 57 slides left and right. The up and down sliding of the hinge rod 54 will drive the upper fixing clamp 55 to slide up and down, so as to fix the shielded cable and prevent the shielded cable from deforming during cutting.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
