[0030] A strip-shaped housing 28 is fixedly installed at the top of the inner part of the frame 10. The bottom and front bottom of the strip-shaped housing 28 are open structures. An adjusting motor 29 is fixedly installed at the top of one side of the strip-shaped housing 28, and the adjusting motor 29 is energized and connected to the control switch 11. An adjusting screw 30 is rotatably installed at the top of the inner part of the strip-shaped housing 28. The output shaft of the adjusting motor 29 passes through one side of the strip-shaped housing 28 and is fixedly connected to one side of the adjusting screw 30. A threaded sleeve 31 is threadedly installed inside the strip-shaped housing 28 and outside the adjusting screw 30. A positioning slider 38 is fixedly installed at the top of the threaded sleeve 31. A positioning groove 39 is opened through the top of the strip-shaped housing 28, and the positioning slider 38 is slidably installed through the groove. Inside the positioning groove 39, the interaction between the positioning slider 38 and the positioning groove 39 enables the threaded sleeve 31 to achieve better stability during movement. A connecting block 32 is fixedly installed at the bottom of the threaded sleeve 31, and a transmission rack 33 is fixedly installed at the bottom of the connecting block 32. The transmission rack 33 is meshed with the transmission gear 25. A first rubber block 34 and a second rubber block 35 are fixedly installed at both ends of the transmission rack 33, respectively.

The side of the first rubber block 34 away from the transmission rack 33 is in contact with the first pressure sensor 36, and the second rubber block 35 is horizontally aligned with the second pressure sensor 37.

[0031] Working principle: First, the mounting base 1 is fixedly installed using mounting bolts that match the diameter of the mounting hole 2, thereby achieving the fixed installation of the entire device. Then, the crystal head that needs to be crimped is placed inside the five crimping grooves 4 on the top of the mounting base 3, and then the wire is manually fed into the square hole of the crystal head.

[0032] Then, control switch 11 starts the adjusting motor 29. The adjusting motor 29 drives the adjusting screw 30 to rotate, which in turn moves the threaded sleeve 31. The threaded sleeve 31 causes the positioning slider 38 to slide inside the positioning groove 39, ensuring better stability during movement. Simultaneously, the threaded sleeve 31 moves the connecting block 32, which in turn moves the transmission rack 33. The transmission rack 33 causes the first rubber block 34 to disengage from the first pressure sensor 36. At the same time, the transmission rack 33 drives the transmission gear 25 to rotate, which in turn drives the transmission shaft 24 to rotate within the positioning sleeve 26. The internal rotation is achieved by the drive shaft 24 driving the driven bevel gear 23 to rotate, which in turn drives the synchronous bevel gear 22 to rotate. The synchronous bevel gear 22 then drives the rotating shaft 16 to rotate within the two positioning frames 17, ensuring better stability of the rotating shaft 16 during rotation. Simultaneously, the rotating disk 18 drives the connecting shaft 19 to move, which in turn drives the movable bar 20 to move. The movable bar 20 pushes the movable plate 12 downward via the movable shaft 21, and the movable plate 12 drives the positioning slide rod 14 to slide within the positioning sleeve 13, ensuring better stability of the movable plate 12 during movement.

[0033] Simultaneously, the movable plate 12 drives the strip plate 5 to move downwards, and the strip plate 5 drives the crimping seat 6 to move downwards. During this process, when the threaded sleeve 31 moves to the middle of the adjusting screw 30, the rotating disk 18 rotates half a turn, and the bottom of the crimping seat 6 moves down into the crimping groove 4. At the same time, the crimping seat 6 moves down to perform crimping and forming operations on the crystal head and wire harness terminals inside the crimping seat 6. After the threaded sleeve 31 moves to the other end of the adjusting screw 30, the transmission rack 33 drives the second rubber block 35 to move to contact the second pressure sensor 37. At this time, the rotating disk 18 completes the half-turn rotation operation, and the second pressure sensor 37 is squeezed and sends a signal. The control switch 11 receives the signal and controls the adjusting motor 29 to stop working, completing the crimping and forming operation of five crystal head wire harness terminals. Then, the operator manually removes the crimped crystal head wire harness terminals.
