The fixing component includes a rectangular box 3 with openings on the left and right sides, a U-shaped wire groove 4, a lower clamping jaw 5, an upper clamping jaw 6 and an adjusting screw 7. The U-shaped wire groove 4 is arranged on the inner bottom surface of the rectangular box 3 and both ends extend out from the left and right side openings of the rectangular box 3. The lower clamping jaw 5 is arranged on the U-shaped wire groove 4 located inside the rectangular box 3. The upper clamping jaw 6 is movably arranged between the front and rear side walls of the rectangular box 3 and corresponds to the lower clamping jaw 5. The adjusting screw 7 is threadedly penetrated through the top of the rectangular box, and its lower end is vertically downward and arranged on the upper clamping jaw 6. A touch screen 8 is arranged on the front side of the chassis 1. The driving motor 2 and the touch screen 8 are respectively connected to the controller. Among them, the chassis is composed of a sheet metal box and an aluminum plate on the top. An openable box door is arranged on one side of the sheet metal box. A handle is arranged on the box door, and a reserved through hole for handle installation can be seen from the figure. The driving motor is connected with a servo driver, and the servo driver is connected to the controller. Through the servo driver, precise positioning is achieved. In order to conform to the ergonomic design, the upper part of the front side of the chassis is designed as a slope, so that the touch screen is inclined, which is convenient to view and not easy to reflect light.

[0022] During use, place at least one connector on one side of the U-shaped wire groove. The front end of the connector and its front waterproof ring should be located outside the U-shaped wire groove. The wire at the rear side of the connector is placed along the U-shaped wire groove and extends into the rectangular box. The wire of the connector is fixed by the lower clamping jaw and the upper clamping jaw. Straighten the wire, measure the length from the front waterproof ring of the connector to the center of the rectangular box, input the length on the touch screen, and the motor speed will be automatically brought out. Set the rotation holding time (usually 10s), drive the motor to act, drive the connector and the waterproof ring to rotate. After the rotation stops, record the position of the waterproof ring (i.e., the seal) on the connector to determine whether the waterproof ring falls off at a certain rotational speed, and then determine whether its holding force meets the requirements. If the position remains unchanged, it can be considered that the waterproof ring does not fall off and its holding force meets the requirements; if the position changes, it can be considered that the waterproof ring falls off and its holding force does not meet the requirements. Of course, two connectors can also be placed on both sides of the U-shaped wire groove at the same time. At this time, the distances from the front waterproof rings of the two connectors to the center of the rectangular box should be equal or close.
