[0019] The right lower end of oil cylinder 1 is fixedly connected with a hand grip 2, and the lower end of the oil cylinder 1 is fixedly connected with a supporting handle 3 on the left side; the inside of the hand grip 2 and the supporting handle 3 is installed with a battery to supply power to the oil pump group 18, and a wire can also be used to supply power to the oil pump group 18; the power supply mode is diversified and can be suitable for different working scenes.

[0020] Four oil pumps are installed in the oil pump group 18, and the oil cylinder 1 is filled with hydraulic oil; the oil cylinder 1 is communicated with the inside of the four oil pumps respectively; the hydraulic oil in the oil cylinder 1 flows into the inside of the four oil pumps respectively; the right end of the oil cylinder 5 is provided with a first oil valve 15, and the left end of the oil cylinder 5 is provided with a second oil valve 16; the oil pumps are connected with the first oil valve 15 and the second oil valve 16 through pipelines respectively; each pair of oil pumps is connected to the first oil valve 15 and the second oil valve 16 through a conduit respectively, that is, the first oil valve 15 is connected with two oil pumps through two conduits respectively, and the second oil valve 16 is connected with the other two oil pumps through two conduits respectively (the two oil pumps connected with the first oil valve 15 and the second oil valve 16 respectively pump hydraulic oil in opposite directions); only one of the two oil pumps connected with the first oil valve 15 works, and only one of the other two oil pumps connected with the second oil valve 16 works; the left end of the hand grip 2 is provided with a trigger 4; the oil pumps connected with the first oil valve 15 and the second oil valve 16 respectively need to be switched to any corresponding oil pump circuit by operating the trigger 4, so that the first oil valve 15 and the second oil valve 16 can work with any corresponding oil pump.

[0021] The trigger 4 is provided with four circuit switches for controlling each oil pump. The trigger 4 is provided with two positions, each of which controls the circuit of two oil pumps respectively (the two oil pumps respectively refer to one of the oil pumps connected to the first oil valve 15 and one of the oil pumps connected to the second oil valve 16). The power supply circuit of each two oil pumps is switched by pulling the trigger 4. When the trigger 4 is pulled to the corresponding position, the power supply of each two oil pumps connected to the position of the trigger 4 is turned on, so that the corresponding oil pump can work.

[0022] When the cable core joint needs to be compressed, the left hand holds the handle 3, the right hand holds the handle 2, the connector 19 connects the oil cylinder 5 and the oil pump group 18 together, the connector 19 can provide a supporting fulcrum for the oil cylinder 5 when holding the handle 2 and the handle 3, so as to align the cable core joint to be compressed by the supporting arm 8. Each core joint of the cable is respectively inserted between the fixed die 7 and the movable die 6 on each supporting arm 8, and the second die 12 and the first die 11 on the same supporting arm 8 are respectively located on the left and right sides of the adjacent joint, so as to complete the process of placing the cable core joint in the wire pressing position between the fixed die 7 and the movable die 6. A reset power button is additionally installed near the trigger 4. The right thumb presses the reset power button to turn on the power supply of the trigger 4 (it needs to be pressed all the time, and the power will be turned off when it is released). Then the right index finger pulls the trigger 4, and the trigger 4 is switched to the first position. One of the oil pumps connected to the first oil valve 15 sucks the hydraulic oil from the inside of the oil cylinder 1 and pumps it into the inside of the oil cylinder 5 on the right side of the piston 14. At the same time, one of the oil pumps connected to the second oil valve 16 sucks the residual hydraulic oil in the inside of the oil cylinder 5 on the left side of the piston 14 and pumps it back into the inside of the oil cylinder 1. At this time, the oil pressure in the inside of the oil cylinder 5 on the left side of the piston 14 is less than the oil pressure in the inside of the oil cylinder 5 on the right side of the piston 14. The hydraulic oil in the inside of the oil cylinder 5 on the right side of the piston 14 pushes the piston 14 to the left, and the piston 14 simultaneously moves the plurality of push-pull rods 13 to the left along the left end of the oil cylinder 5, so that the movable die 6 moves towards the fixed die 7. The joint of the cable core is extruded to the right of the fixed die 7 by the movable die 6, and the joint of the cable core is compressed between the movable die 6 and the fixed die 7 on the same side.

At this time, the two oil pumps will be closed, and the circuit will be switched to the other oil pump connected to the first oil valve 15 and the second oil valve 16 respectively. That is, the other oil pump connected to the first oil valve 15 will be started, and the other oil pump connected to the second oil valve 16 will also be started. The other oil pump connected to the first oil valve 15 will suck the hydraulic oil in the oil cylinder 5 to the right of the piston 14 and pump it back to the inside of the oil tank 1. The other oil pump connected to the second oil valve 16 will suck the hydraulic oil in the oil tank 1 and pump it into the oil cylinder 5 to the left of the piston 14. The oil pressure in the oil cylinder 5 to the left of the piston 14 is greater than that to the right of the piston 14. The hydraulic oil in the oil cylinder 5 to the left of the piston 14 pushes the piston 14 to move right in the oil cylinder 5. The piston 14 will move the multiple push-pull rods 13 right along the left end of the oil cylinder 5 at the same time, so that the movable head 6 moves away from the fixed head 7, the first die 11 and the second die 12 are separated from the surface of the cable core joint, and the cable core joint can be separated from the position between the movable head 6 and the fixed head 7. That is, the pressed cable core joint can be separated from the head machine. Then, the trigger 4 and the reset power button are released. The built-in torsion spring of the trigger 4 will return to its original position and make the power switch disengage from the two gears. After the power button is released, the entire oil pump group 18 will be powered off.
