[0023] As attached Figure 1 As shown, an adjustable wire-stopping mechanism for ultrasonic wire harness welding comprises a terminal positioning seat 1, a wire-stopping block 2, a base 3, a wire-stopping block linear pushing portion 4, and a wire-stopping block stroke limiting portion 5.

[0024] Combined with Figure 3 and attached Figure 4 As shown, the linear push part 4 of the stop line block includes a single-rod power cylinder 41, a slide 42, an oblique groove 43, a pin 44, and a waist-shaped hole 45. The cylinder body of the single-rod power cylinder 41 is fixed on the base 3, the piston rod of the single-rod power cylinder 41 is connected to the slide 42, the slide 42 is slidably connected in the base 3, the slide 42 is provided with an oblique groove 43, the base 3 is provided with a waist-shaped hole 45, the bottom of the stop line block 2 is connected to one end of the pin 44, the other end of the pin 44 is placed in the oblique groove 43, and the pin 44 passes through the waist-shaped hole 45.

[0025] The piston rod of the single-rod power cylinder 41 is extended and retracted to drive the slide 42 to move horizontally and linearly. When the slide 42 moves, the bottom end of the pin 44 is driven to move along the oblique groove 43, and the rod body of the pin 44 moves linearly along the waist-shaped hole 45, and the pin 44 can drive the stopper block 2 to move linearly back and forth on the base 3.
