[0022] The lifting seat 1 is provided with at least one connecting arm 11 , the length direction of the connecting arm is parallel to the radial direction of the lifting seat, and the upper cutter and the lower cutter are respectively connected to the corresponding lifting seat through the connecting arm.

[0023] The upper cutter 31 also includes an upper cutter seat 313 and a mounting seat 314. The upper cutter head 311 and the upper abutment portion 312 are integrally installed and fixed below the upper cutter seat. The mounting seat is fixedly installed on the upper end of the upper cutter seat, and the size of the mounting seat is larger than the size of the upper cutter seat. A accommodating cavity is provided in the connecting arm 11 corresponding to the upper cutter. The internal size of the accommodating cavity is adapted to the installation, and the opening size of the accommodating cavity is adapted to the upper cutter seat. The pressure sensor is located in the accommodating cavity and fits the top of the mounting seat.

[0024] The lower support portion 322 is provided with a plurality of through grooves with an arc-shaped cross-section. The lower cutter head 321 and the upper cutter head 311 both include a plurality of arc-shaped cutting edges symmetrically arranged along the central axis of the lower cutter head or the upper cutter head and adapted to the wiring harness. The number and position of the through grooves are adapted to the arc-shaped cutting edges of the lower cutter head to facilitate guiding and positioning of the wiring harness.

[0025] The lifting seat 1 is provided with a guide column 2, which is in the shape of a vertical column. The two lifting seats are both sleeved on the guide column and can move in opposite directions along the guide column.

[0026] A return spring 12 is installed between the lifting seats 1, and both ends of the return spring are connected to the opposite sides of the two lifting seats so as to facilitate the return of the lifting seats after movement.

[0027] The twisted pair wire opening device of this embodiment uses the relative movement of the lifting seat to drive the upper and lower blade heads closer together when stripping the wires. The upper and lower blade heads are misaligned but still have opposite side faces close to each other to ensure that the blades of the upper and lower blade heads are basically located on the same vertical plane. When the upper and lower blade heads approach each other, the upper abutment and the lower support plate also approach and fit each other. The lower support part undergoes elastic deformation under pressure to prevent obstruction of the relative movement between the two blades. At the same time, the pressure sensor also converts the pressure generated by the direct contact between the upper abutment and the lower support part into the pressure generated by the blade on the wire harness and outputs it, thereby controlling the working state of the driving mechanism of the lifting seat (not shown), adjusting its driving pressure and other working parameters, and ensuring that the pressure on the wire harness does not exceed expectations.

[0028] The beneficial effects of the present invention are: through the pressure sensor cooperating with the abutment part and the support part in the tool, precise pressure control of the wire harness when opening the wire harness is achieved; at the same time, the cutter adopts a multi-blade symmetrical design, which can accommodate multiple wires for opening at the same time, ensuring that the wires are under uniform pressure, helping to maintain the wire lay pitch from being destroyed while improving the integrity and strength of the wire harness, and avoiding damage caused by excessive pressure on the wires.

Ordinary technicians in this field can change, modify and modify the above embodiments within the scope of the present invention.
