DETAILED DESCRIPTION

[0020] The utility model is further described in connection with the drawings.

[0021] As Figure 1 shown, a novel wide copper wire bending wrench, including clamping mechanism 1 and stop lever 4, clamping mechanism 1 includes holding portion 2 and jaw 3 (clamping mechanism 1 is the conventional wrench), holding portion 2 and jaw 3 are connected through the mode of welding, the two jaw arms of jaw 3 are mutually crossed, the two holding rods of holding portion 2 are fixed on the corresponding jaw arm through the mode of welding respectively, jaw 3 is clamped through holding portion 2, stop lever 4 is fixed on the side of the side of jaw 3 through the mode of welding, stop lever 4 bottom is fixed on the jaw arm at the bottom through the mode of welding, when bending, the end of wide copper wire is embedded in the jaw, wide copper wire and jaw 3 are on the same straight line, the side of wide copper wire leans on stop lever 4, stop lever 4 is located at the top of jaw, jaw 3 clamps wide copper wire, swing clamping mechanism 1 swings to the right (for example), the bending point of wide copper wire is the position of contact with stop lever 4, so that the end of wide copper wire bends to the right. Figure 1

[0022] As Figure 2 shown, the other side of jaw 3 is also provided with stop lever 4, that is, stop lever is fixed on the left and right sides of jaw 3 through the mode of welding, stop lever 4 limits the two sides of lead, the end of wide copper wire is inserted into jaw 3 and clamped, clamping mechanism 1 can swing left and right, when clamping mechanism 1 swings to the right, the right side of wide copper wire contacts with the right stop lever 4, so that the stop lever bends to the right, when clamping mechanism 1 swings left and right, the left side of wide copper wire contacts with the left stop lever 4, so that the stop lever bends to the left, the up and down bending of wide copper wire can be realized by swinging clamping mechanism 1 up and down.

[0023] As Figures 3-6 shown, when the width of wide copper wire is greater than the width of jaw, the gap between the two stop levers needs to be adjusted, width adjusting assembly 5 is arranged between the two stop levers 4, locking module 10 for locking width adjusting assembly 5 is arranged in jaw 3, that is, when jaw 3 clamps, the width between stop levers 4 is locked, that is, the width between the two stop levers 4 is adjusted through width adjusting assembly 5, wide copper wire is clamped between the two stop levers 4, then jaw 3 clamps wide copper wire to bend.

[0024] ​The top of the two guide rods 4 is outwardly inclined to form a horn 14, which facilitates the clamping of the wide copper wire between the two guide rods 4. The bottom of the two guide rods 4 is provided with a width adjusting assembly 5, which is installed at the bottom of the jaw 3. The width adjusting assembly 5 enables the guide rods to move forward and backward along the jaw, i.e., the left guide rod 4 moves forward along the sidewall of the jaw 3, and the right guide rod 4 moves backward along the sidewall of the jaw 3. In this way, the distance between the two guide rods 4 is adjusted. The forward and backward movement of the guide rods 4 of the present application can reduce the torque. If the guide rods 4 move left and right along the jaw 3, the force arm is extended, the torque is increased, and the connection between the guide rods 4 and the jaw 3 is unstable.

[0025] The width adjusting assembly 5 includes a mounting seat 6, a sliding seat 7, and an elastic return assembly 9. The mounting seat 6 is fixed to the bottom of the jaw 3 (i.e., the bottom of the jaw arm) by welding. The sliding seat 7 is installed on the left and right sides of the mounting seat 6 and moves forward and backward along the sidewall of the jaw 3. The guide rod 4 is installed on the sliding seat 7 by welding and moves forward and backward with the sliding seat 7. The elastic return assembly 9 is arranged between the sliding seat 7 and the mounting seat 6. The guide rod 4 is moved to the middle from the front and rear of the jaw by the elastic return assembly 9, so that the guide rod clamps the wide copper wire. A locking module 10 is arranged between the sliding seat 7 and the mounting seat 6 and is locked when the jaw 3 is closed. When the jaw 3 clamps the wide copper wire, the locking module 10 locks the position of the guide rod 4, preventing the guide rod 4 from moving forward and backward and affecting the bending point during bending. The clamping method of the wide copper wire of the present application is changed, i.e., the wide copper wire is perpendicular to the jaw 3.

[0026] The locking module 10 comprises a lifting rod 11, a locking rack 12 and a locking rack groove 13. The sliding seat 7 is provided with sliding grooves 8 on both sides, and the sliding seat 7 is clamped in the sliding grooves 8 for sliding. Then, the outer side of the sliding groove 8 is sealed by welding. The top of the mounting seat 6 is provided with a long strip-shaped slot for the sliding of the stop rod 4. The stop rod 4 is fixedly connected with the sliding seat 7 through the slot in the top of the mounting seat 6. The locking rack groove 13 is provided on the inner side of the sliding seat 7. The locking rack 12 corresponding to the locking rack groove 13 is installed in the sliding groove 8. That is, the notch for embedding the locking rack 12 is provided on the inner side of the sliding groove 8. The locking rack 12 moves left and right in the notch. The vertical through hole is provided on the front arm of the jaw 3 at the bottom. The lifting rod 11 is inserted into the through hole. The lifting rod 11 moves up and down along the through hole. The mounting hole 15 is provided at the center of the mounting seat 6. The lifting rod 11 extends into the mounting hole 15. The bottom of the lifting rod 11 is fixedly provided with a trigger rod 16 by welding. The trigger rod 16 extends to both sides. The left and right ends of the trigger rod 16 extend into the sliding grooves 8 on both sides of the mounting seat 6. The bottom of the trigger rod 16 is inclined (inclined from the inner side to the outer side upward). The top surface of the locking rack 12 is inclined (inclined from the inner side to the outer side upward) and matched with the inclined surface of the trigger rod 16. The spring is fixed between the locking rack 12 and the sliding groove 8 by welding. The spring pulls the locking rack 12 inward and separates it from the locking rack groove 13. When working, the wide copper wire is clamped into the jaw 3. The wide copper wire is located between the stop rods 4. The jaw 3 is closed to press the wide copper wire. The lifting rod 11 is pressed downward when the wide copper wire is pressed tightly. The trigger rod 16 is pressed downward. The inclined block presses the locking rack 12 outward to engage with the locking rack groove 13. The sliding seat 7 cannot move when the jaw 3 presses the wide copper wire tightly.

[0027] The stop rod 4 is a circular stop rod 4. The protective sleeve 17 is sleeved on the outer wall of the stop rod 4. The protective sleeve 17 rotates on the outer wall of the stop rod 4 to prevent the stop rod 4 from being moved due to excessive friction with the wide copper wire. When the bending position needs to be adjusted, the stop rod 4 is clamped on the wide copper wire. When the jaw 3 moves along the wide copper wire, the friction resistance increases when the stop rod 4 is clamped on the edge of the wide copper wire. It is difficult to move. The stop rod 4 is provided with a rotating protective sleeve 17. The protective sleeve 17 contacts the outer wall of the wide copper wire, so that the friction resistance is not reduced, and the jaw 3 can move on the wide copper wire.

[0028] The elastic return assembly 9 is a return spring. The return spring is embedded in the sliding groove 8. One end of the return spring abuts against the end of the sliding seat 7. The other end of the return spring is fixed on the inner wall of the sliding groove 8 by welding. The return spring on the left side of the jaw is located at the front end of the sliding seat 7. The return spring on the right side of the jaw is located at the rear end of the sliding seat 7. The stop rods on both sides are squeezed to the middle by the return spring.
