[0060] The ejection mandrel 43 is fixedly connected to the external threaded rod 42 , or the ejection mandrel 43 is connected to the external threaded rod 42 via an adjustment device 5 .

[0061] As a further implementation:

[0062] The adjusting device 5 includes a through hole 51 arranged at the center of the external threaded rod 42, a built-in convex ring 52 arranged in the middle of the through hole 51, and anti-rotation plugs 53 uniformly distributed circumferentially on the left side of the inner wall of the through hole 51.

A cross-shaped screwdriver can be used to drive the rotating terminal 54 to rotate through the adjustment opening.

[0064] The specific implementation methods are as follows:

[0065] Step 1: Clamp and fix the connecting sleeve 8:

[0066] As the instruction manual Figure 3 .Instruction manual attached Figure 4 As shown:

[0067] Hold the holding housing 1, insert the side transverse tube 12 from right to left into the connecting transverse cylinder 81, the right end of the connecting transverse cylinder 81 presses the pressure inclined surface 26 to make it retract against the damping of the compression spring 23, until the clamping device 2 completely passes over the right edge of the connecting transverse cylinder 81 and aligns with the clamping ring groove 83, the clamping device 2 pops out to reset and lock the clamping ring groove 83;

[0068] At the same time, the hexagonal inner tube 36 is also sleeved on the fixing nut 94 .

[0069] Step 2, twist the twisting device 3 and remove the fixing nut 94:

[0070] As the instruction manual Figure 5 As shown:

[0071] The rotating motor 37 and the driving gear 38 rotate, driving the driven gear 34, the enlarged outer ring 32, the internal threaded tube 31, the side plate with holes 35, and the internal hexagonal tube 36 to rotate;

[0072] The hexagonal inner tube 36 rotates and drives the fixing nut 94 to rotate and retreat along the fixing screw 93 until it slips off the fixing screw 93.

[0073] Step 3, the ejection device 4 is activated, and the cable terminal head 7 and the connecting sleeve 8 are removed:

[0074] As the instruction manual Figure 6 As shown:

[0075] During step 2, the internal threaded tube 31 rotates to drive the external threaded rod 42 and the ejection mandrel 43 to move leftward relative to the gripping housing 1. When step 2 is completed, the ejection mandrel 43 abuts against the fixing screw 93.

[0076] The ejection core shaft 43 continues to move to the left relative to the holding shell 1, but because the ejection core shaft 43 is blocked by the fixing screw 93, the holding shell 1, the clamping device 2, the torsion device 3, the cable terminal head 7, and the connecting sleeve 8 move to the right relative to the ejection core shaft 43 and the fixing screw 93, completing the disassembly of the cable terminal head 7 and the connecting sleeve 8.

[0077] Furthermore, the method further comprises step 4 of separating the connecting sleeve 8 and the disassembly device 6:

[0078] The sliding ring 27, the active insertion rod 28, and the limiting socket 29 are pushed to the left, and the active insertion rod 28 acts on the reset inclined surface 25 to drive the clamping slider 21 to overcome the damping of the compression spring 23 and lift upward, and the clamping device 2 slides out of the clamping ring groove 83. At this time, the disassembly device 6 can be removed from the connecting sleeve 8.

[0079] Furthermore, the action timing of the ejection device 4 can also be adjusted:

[0080] The rotating terminal 54 and the driving screw 56 are twisted, and the driving screw 56 acts on the driven screw hole 57, thereby driving the ejection mandrel 43 to move in the left and right directions. By adjusting the position of the ejection mandrel 43, it is ensured that the ejection mandrel 43 just pushes against the fixing screw 93 at the end of step 2.
