DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] A drop hammer type crimping tool pliers for power line engineering construction, such as Figure 1 and Figure 3As shown, it includes a crimping pliers 1, a base 2 and a body 3, the body 3 is fixed on the upper surface of the base 2, a U-shaped frame 4 is connected to the left side of the body 3, the crimping pliers 1 is slidably installed on the U-shaped frame 4, the crimping pliers 1 is integrally formed with a crimping pliers body 101 and a crimping pliers head 102, the crimping pliers head 102 is fixed to the lower surface of the crimping pliers body 101, and the crimping pliers head 102 is a quadrangular platform structure, the crimping pliers 1 presses the wiring terminal to connect the electrical wire and the wiring terminal together, wherein the crimping pliers head 102 with a quadrangular platform structure can concentrate the force more during the crimping process, and the crimping is tighter, the right side of the crimping pliers 1 is connected to a movable column 5, and a chamber 6 is provided in the body 3, and left sliding holes 7 are respectively provided on the left and right outer sides of the body 3. The movable column 5 is slidably installed in the left and right sliding holes 8, and the movable column 5 can drive the crimping clamp 1 to move synchronously when the left and right sliding holes 7 and 8 move. The outer wall of the movable column 5 is also connected to one end of a reset spring 13, and the other end of the reset spring 13 is connected to the upper end surface of the chamber 6. When the movable column 5 moves upward, the crimping clamp 1 also moves upward, and the crimping clamp 1 moves away from the machine base 2, leaving space for placing the terminal. At this time, the reset spring 13 is compressed, and when the reset spring 13 rebounds and resets, the movable column 5 moves downward, and at the same time, the crimping clamp 1 moves downward to reset. At the same time, under the action of the rebound force of the reset spring 13, the crimping clamp head 102 can better press the terminal.

[0022] like Figure 2 and Figure 4 As shown, a threaded groove 11 is provided on the outer wall of the right half of the movable column 5, and a threaded hole 11 is provided on the limiting nut 9. The right half of the movable column 5 is threadedly connected to the limiting nut 9. By rotating the limiting nut 9, the limiting nut 9 can be moved on the right half of the movable column 5, and a pair of protrusions 12 are also provided on the limiting nut 9. The setting of the protrusions 12 makes it more convenient to rotate the limiting nut 9. A limiting groove 10 matching the limiting nut 9 is also provided on the right sliding hole 8. When the limiting nut 9 is moved so that its left end enters the limiting groove 10, the movable column 5 realizes self-locking of the position, that is, the crimping pliers 1 also realizes position fixation.

[0023] like Figure 1 and Figure 2As shown, a trapezoidal groove 14 is provided on the machine base 2, and the trapezoidal groove 14 is arranged corresponding to the crimping pliers head 102. The wiring terminals and the electrical wires are placed in the trapezoidal groove 14, and then the user uses a hammer to hit the crimping pliers 1 to achieve crimping between the electrical wires and the wiring terminals. A plurality of anti-slip grooves 17 are evenly spaced on the left and right sides of the trapezoidal groove 14 to prevent the wiring terminals from shifting in position during the crimping process, thereby causing crimping errors. A mounting plate 15 is fixed to the lower surface of the machine base 2, and mounting holes 16 are provided at the four corners of the mounting plate 15. The crimping tool pliers are fixed in position by the mounting plate 15 to prevent the crimping tool pliers from tipping over when the user drops a hammer to hit the crimping pliers 1.

[0024] When the utility model is working, the user lifts the movable column 5 to drive the crimping pliers 1 to move up, and a space is generated between the crimping pliers 1 and the trapezoidal groove 14, and the wiring terminal and the electric wire are both placed in the trapezoidal groove 14, and the wiring terminal is sleeved outside the electric wire. In the process before the wiring terminal is placed, the movable column 5 is slidably installed in the left sliding hole 7 and the right sliding hole 8. The outer wall of the right half of the movable column 5 is provided with a threaded groove 11, and the limiting nut 9 is provided with a threaded hole 11. The right half of the movable column 5 is connected to the limiting nut 9 through threads, and the limiting nut 9 is also provided with a pair of protrusions 12. The right sliding hole 8 is also provided with a limiting groove 10 matched with the limiting nut 9. The user holds the protrusion 12 and lifts it, thereby driving the limiting nut 9 and the movable column 5 to move up. When the movable column 5 reaches the upper end of the sliding hole, it is rotated clockwise. The protrusion 12, that is, the limiting nut 9 rotates clockwise and moves to the left. When the left end of the limiting nut 9 enters and is stuck in the limiting groove 10, the movable column 5 realizes self-locking of the position, that is, the crimping pliers 1 also realizes fixed position. At this time, the user places the terminal in position, which can free the user's arm and does not need to lift the movable column 5 for a long time to place the terminal. After the placement is completed, the user uses an external hammer to hit the crimping pliers 1 and rotates the protrusion 12 counterclockwise, that is, the limiting nut 9 rotates counterclockwise and moves to the right. After leaving the limiting groove 10 counterclockwise, the movable column 5 and the crimping pliers 1 both move downward, and then the crimping pliers 1 is pressed on the outer wall of the terminal. The user then uses a hammer to knock the crimping pliers 1 to achieve crimping between the electrical wire and the terminal.
