[0006] To achieve the above objectives, the present invention provides the following technical solution: a wire and cable cutting device with adjustable cutting spacing, comprising: a workbench for installation, and a fixing plate fixedly installed on the rear side of the upper end of the workbench;

[0007] It also includes: a transmission rod, on the upper end of the fixed plate, a handle on the left side of the transmission rod, a first bevel gear on the right end of the transmission rod, a second bevel gear connected to the lower end of the first bevel gear, a first threaded rod connected to the middle of the second bevel gear, a connecting frame connected to the outer side of the first threaded rod, a first grooved wheel and a second grooved wheel connected inside the connecting frame, the second grooved wheel being located to the right of the first grooved wheel, a third grooved wheel at the lower end of the first and second grooved wheels, a first gear and a first motor installed at the front end of the first grooved wheel, the first motor being located in front of the first gear, a transmission belt connected to the outer side of the first gear, a second gear connected to the right end of the transmission belt, a telescopic rod on the right side of the front end of the fixed plate, a support plate at the lower end of the telescopic rod, a fixed connecting block at the lower end of the support plate, a bolt connected inside the fixed connecting block, a blade body and a first spring on the outer side of the bolt, the first spring being located to the right of the blade body;

[0008] A cutting platform is set at the upper middle part of the workbench. A second threaded rod is installed inside the cutting platform, and a sliding plate is connected to the outside of the second threaded rod. A second motor is installed at the right end of the second threaded rod. A sensing plate is set at the upper right side of the sliding plate, and a fixing rod is set at the right side of the sensing plate.

[0013] Preferably, the second threaded rod is connected to the sliding plate by a thread, and the sliding plate forms a sliding structure inside the cutting platform.

[0014] Preferably, the baffle forms a rotating structure on the outside of the fixed rod, and the front and rear ends of the baffle are connected to the torsion spring by a snap-fit ​​method.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the adjustable cutting spacing wire and cable cutting device facilitates the adjustment of the cable size and transmission device distance, facilitates the quick replacement of the cutting blade, and facilitates the controllable adjustment of the cable cutting spacing;

[0016] 1. The device is equipped with a second bevel gear, a connecting frame, and a second grooved wheel. Due to the different widths of cables, in order to be suitable for cutting various cables, the point connection line is placed in the middle of the third grooved wheel. At this time, holding the handle drives the first bevel gear to rotate through the transmission rod, and the first bevel gear drives the first threaded rod to rotate through the second bevel gear. This causes the connecting frame to move downward along the path of the first threaded rod. The connecting frame then drives the first and second grooved wheels to fit against the upper end of the cable according to the width of the cable, ensuring that the cable is in a limited position during transmission and cutting, which facilitates the adjustment of the transmission device distance according to the size of the cable.

[0017] 2. It is equipped with bolts, blade body and first spring. Due to the long-term cutting of the cable by the cutting device, the bottom of the blade body is prone to damage. At this time, the bolt is rotated inside the fixed connecting block. As the thread path moves to the right, it disengages. When the fixed connecting block and the bolt are no longer connected, pinch the blade body wall and pull the bolt to the right. The blade body can then be disassembled and replaced, which facilitates quick replacement of the cutting blade.

[0018] 3. Equipped with a second threaded rod, a sliding plate, and a sensing plate, when the cutting distance needs to be adjusted, the second motor is started to drive the second threaded rod to rotate. When the second threaded rod rotates, it drives the sliding plate to extend to the right. The position of the sliding plate is determined according to the cable cutting length. When the cable output end enters the inside of the sensing plate, it is transmitted to the telescopic rod through the sensor inside the sensing plate. This causes the telescopic rod to drive the lower cutting device to cut the cable, making it easy to controllably adjust the cable cutting spacing. Attached Figure Description

[0027] When it is necessary to clamp and transmit cables of different sizes, such as Figure 1 , Figure 2 and Figure 5As shown, a transmission rod 3 is installed on the upper end of the fixing plate 2, and a handle 4 is provided on the left side of the transmission rod 3. A first bevel gear 5 is provided on the right end of the transmission rod 3. A second bevel gear 6 is connected to the lower end of the first bevel gear 5, and a first threaded rod 7 is connected to the middle of the second bevel gear 6. A connecting frame 8 is connected to the outer side of the first threaded rod 7. A first grooved wheel 9 and a second grooved wheel 10 are connected inside the connecting frame 8, and the second grooved wheel 10 is located to the right of the first grooved wheel 9. A third grooved wheel 11 is provided at the lower end of the first grooved wheel 9 and the second grooved wheel 10. A first gear 12 and a first motor 13 are installed at the front end of the first grooved wheel 9, and the first motor 13 is located in front of the first gear 12. A transmission belt 14 is connected to the outer side of the first gear 12, and a second gear 15 is connected to the right end of the transmission belt 14. First, place the lower end of the cable on... At the upper end of the third grooved wheel 11, the handle 4 is held and the transmission rod 3 drives the first bevel gear 5 to rotate. The lower end of the first bevel gear 5 is connected to the second bevel gear 6 in a meshing manner. The first bevel gear 5 drives the first threaded rod 7 to rotate through the second bevel gear 6, so that the connecting frame 8 moves downward along its path, causing the lower ends of the first grooved wheel 9 and the second grooved wheel 10 to fit against the upper end of the cable. After the limit is set, the first motor 13 is started. When the first grooved wheel 9 is rotated, the first gear 12 is also driven to rotate. The first gear 12 drives the second gear 15 to rotate in the same direction through the transmission belt 14. The transmission belt 14 is fixedly connected to the second grooved wheel 10. Therefore, the first grooved wheel 9 and the second grooved wheel 10 drive the lower end of the cable to be transported and cut to the right through their own friction.

A baffle 28 and a torsion spring 29 are provided on the outside of the fixing rod 27, and the torsion spring 29 is located at the front and rear ends of the baffle 28. When it is necessary to adjust the cable cutting distance, the second motor 25 is started to drive the second threaded rod 23 to rotate, and the second threaded rod 23 drives the sliding plate 24 to move and extend to the right according to the cable cutting distance. At the position of the cutting sliding plate 24, when the output end of the cable is inserted into the induction plate 26 and abuts against the left side of the baffle 28, the induction plate 26 transmits the signal to the telescopic rod 16 through the internal sensing device. The telescopic rod 16 then drives the lower cutting device to cut the cable. After the cable is cut, the cable continues to be input, causing the cut cable to press against the baffle 28 to the right. The baffle 28 flips upward until the cut cable is output. The torsion spring 29 uses its elasticity to drive the baffle 28 back to its original position, thus blocking and limiting the next cable to be cut. This is the usage method of the adjustable cutting spacing wire and cable cutting device.
