[0026] As an embodiment of the utility model, a stopper 13 is arranged above the measuring ruler 12; the stopper 13 is arranged in a U-shape; the stopper 13 is slidably connected to the measuring ruler 12; a circular groove 131 is provided on the inner wall of the U-shaped end of the stopper 13; a pressing block 132 is slidably and sealedly connected in the circular groove 131; the pressing block 132 is connected to the bottom of the circular groove 131 through a supporting spring 133; a pushing groove 134 connected to the circular groove 131 is provided at the upper end of the stopper 13; a pushing rod 135 is slidably connected in the pushing groove 134.

[0028] As an embodiment of the present utility model, a mounting groove 17 is provided on a side of the stopper 13 close to the workbench 1; a clamping block 171 is slidably connected in the mounting groove 17; a screw 172 is rotatably connected in the mounting groove 17; the threads at both ends of the screw 172 are arranged oppositely; two clamping blocks 171 are provided; the two clamping blocks 171 are connected to the screw 172 in a spiral transmission; a hand wheel 173 fixedly connected to the screw 172 is rotatably connected to the side wall of the clamping block 171;

[0029] When working, the existing cutting device often requires manual support of the wire when cutting the wire. During manual support, the placement position and placement angle of the wire are determined by observation by the operator, and the operator is often a plane cutting device, which makes it impossible for the operator to observe the state of the wire from the best angle, making it difficult for the operator to accurately judge the position and angle of the wire; the wire is prone to deflection during the cutting process, resulting in an uneven cut surface of the wire, which makes the wire poorly matched with the connection terminal or other components, increases the difficulty of connection, and causes an unstable connection, affecting the stability and reliability of the electrical system of the new energy vehicle;

[0030] In this regard, the utility model sets two blocking plates 142 so that the two blocking plates 142 can block the wires, fix the position and angle of the wires, and keep the wires in a straight state under the blocking of the blocking plates 142, thereby preventing the wires from being easily deflected during the cutting process, ensuring the flatness of the wire cutting surface, thereby improving the matching degree between the wires and the connecting terminals or other components, reducing the connection difficulty, and improving the connection firmness of the wires, thereby improving the stability and reliability of the electrical system of the new energy vehicle;

[0031] In the initial state, the pushing groove 134 is filled with hydraulic oil, and the pressing block 132 extends out of the circular groove 131 under the push of the support spring 133 and presses against the side wall of the measuring ruler 12. The user first presses the pushing rod 135 so that the pushing rod 135 pushes the hydraulic oil in the pushing groove 134 into the circular groove 131 connected to the pushing groove 134, so that the hydraulic oil entering the circular groove 131 can push the pressing block 132 in the circular groove 131 to move away from the measuring ruler 12, so that the pressing block 132 can squeeze the supporting spring 133. The support spring 133 penetrates into the circular groove 131 until the abutting block 132 is no longer in contact with the measuring ruler 12, pushing the stopper 13 so that the stopper 13 can move along the measuring ruler 12 in a direction away from the workbench 1; since the distance between the end of the measuring ruler 12 connected to the workbench 1 and the lower blade 113 is fixed, when the stopper 13 is slid, the scale of the measuring ruler 12 corresponding to the stopper 13 plus the distance between the measuring ruler 12 and the lower blade 113 is the length of the wire cut, and the wire length cut as needed After the sliding stopper 13 moves to the designated scale value of the measuring ruler 12, the pushing rod 135 is stopped, so that the pushing rod 135 no longer generates a driving force on the hydraulic oil in the driving groove 134, so that the pressing block 132 is no longer pushed by the hydraulic oil, so that the pressing block 132 extends out of the circular groove 131 and presses against the measuring ruler 12 under the push of the restoring force of the supporting spring 133; because the pressing block 132 is provided with a V-shaped groove 136 on one side close to the measuring ruler 12, the side of the pressing block 132 in contact with the measuring ruler 12 is rubbed against the surface of the pressing block 132. The friction coefficient is increased, thereby increasing the friction between the abutting block 132 and the side wall of the measuring ruler 12, so that the stopper 13 can be clamped with the measuring ruler 12 under the action of the abutting block 132; thereby improving the connection stability between the stopper 13 and the measuring ruler 12; and the abutting block 132 is made of fluororubber material, so that the abutting block 132 has good wear resistance and aging resistance; thereby improving the service life and use effect of the abutting block 132, so that the practicality of the utility model is further improved;

[0032] When the position of the stopper 13 is determined, the hand wheel 173 on one side of the stopper 13 is first rotated so that the hand wheel 173 drives the screw 172 connected thereto to rotate, so that the screw 172 drives the clamping block 171 in the mounting groove 17 to move away from each other. At this time, the two clamping blocks 171 are in an open state, and then one end of the wire is placed between the two clamping blocks 171 so that the wire contacts the stopper 13, and then the hand wheel 173 is rotated in the opposite direction so that the hand wheel 173 drives the screw 172 to rotate, so that the screw 172 drives the two clamping blocks 171 to clamp the wire, and then pulls the wire to a straight state; at this time, the wire is located at the upper end surface of the stopper 13, and since the stopper 13 is located at one end of the strip groove 141 close to the frame 11 in the initial state, when the user rotates Before the screw rod 143 is inserted, the user first places the telescopic rod 15 between the two guide blocks 14, pushes the connecting rod 152 and the fixed rod 151 to move towards each other, so that the connecting rod 152 squeezes the fixed spring 154 in the groove 153 and enters the groove 153, so that the length of the connecting rod 152 and the fixed rod 151 is reduced, and then the connecting rod 152 and the fixed rod 151 are respectively aligned with the worm 146 of the inner guide block 14, so that the rectangular grooves 155 at both ends of the connecting rod 152 and the fixed rod 151 are aligned with the rectangular ends of the two screw rods 172, and the connecting rod 152 is slowly loosened, so that the connecting rod 152 drives the rectangular groove 155 to approach the rectangular end of the worm 146, so that the rectangular end of the worm 146 close to the connecting rod 152 is inserted into the connecting rod 152, and similarly, the rectangular end of the worm 146 near the fixed rod 151 is inserted into the rectangular groove 155 of the fixed rod 151; at this time, the two worms 146 are connected by the telescopic rod 15; since one end of the worm 146 far away from the measuring ruler 12 is fixedly connected with a handle, at this time, the user rotates the handle so that the handle can rotate the worm 146, and at this time, the other worm 146 is driven by the telescopic rod 15 to rotate, and during the rotation of the worm 146, the worm 146 can drive the worm wheel 145 meshing with it to rotate, so that the worm wheel 145 drives the screw rod 143 fixedly connected to it to rotate, so that the screw rod 143 can drive the blocking plate 142 to slide along the strip groove 141 in the direction close to the wire until the blocking plate 142 is aligned with the stretched straight wire. The wire is in contact, at this time the worm 146 is stopped, and then the electro-hydraulic push rod 111 is controlled to descend, so that the electro-hydraulic push rod 111 pushes the upper blade 112 to descend, so that the upper blade 112 cooperates with the lower blade 113 to cut the wire; when the wire is cut, the user turns the hand wheel 173 again to open the clamping block 171, and removes the cut wire. At the same time, the cut end of the long wire is prevented from being clamped again between the two clamping blocks 171, and then the wire clamped by the clamping block 171 is pulled to be close to the blocking plate 142. At this time, the wire is in a straight state, so the user does not need to repeatedly observe the placement position and placement angle of the wire, which greatly reduces the work intensity of the staff, improves the cutting efficiency of the wire, and further improves the practicality of the utility model;The arrangement of the corrugated sheet 16 enables the corrugated sheet 16 to block the notch of the strip groove 141, thereby preventing external dust and wire cut debris from splashing into the strip groove 141, thereby preventing external dust and wire cut debris from blocking the screw rod 143 in the strip groove 141, so that the screw rod 143 can stably and effectively drive the blocking plate 142 to slide in the strip groove 141, so that the practicality of the utility model is further improved. ;
