The utility model is simple to operate. The connecting sleeve is placed on the pressing platform 2, the insulating layer on the outside of the cable is stripped, and the stripped connecting ends are inserted into the two ends of the connecting sleeve. The screw 404 is rotated, and the lower pressing seat 401 connected thereto moves downward under the action of the sliding block 601 and the first sliding groove 301, so that the pressing block 403 is pressed toward the connecting sleeve. As the rotating rod 405 rotates, the connecting sleeve is continuously squeezed, so that the connecting sleeve and the cable placed inside it are squeezed into a whole. This process is not affected by the strength of the operator. According to the actual crimping situation, the screw 404 is rotated a corresponding number of turns to complete the connection between the cables.

[0029] The support frame 3 is provided with a wire stripping assembly 7 mounted on the side thereof. The wire stripping assembly 7 is composed of a wire payout seat 701, a knife seat 703, and a second spring 705. The wire payout seat 701 is mounted on the side thereof. One end of the knife seat 703 is rotatably mounted on the wire payout seat 701. The other end of the knife seat 703 is connected to the wire payout seat 701 via the second spring 705. A wire cutting groove is provided on the top of the wire payout seat 701. A blade 704 is mounted on the bottom of the knife seat 703. The position of the blade 704 corresponds to the position of the wire cutting groove. The cable is placed in the placement groove on the wire payout seat 701, and the knife seat 703 is pressed downward so that the blade 704 in the knife seat 703 cuts into the cable insulation layer. The cable is then rotated so that the blade 704 can cut the cable insulation layer, thereby completing the stripping of the cable's outer insulation layer. No other tools are required to further strip the cable, thereby shortening the time required for cable crimping and improving the work efficiency during crimping.

[0030] The base 1 is provided with a second chute 101, in which a bidirectional screw rod 5 is rotatably connected. One end of the bidirectional screw rod 5 passes through a handwheel 501 provided on the side of the base 1.

The cable from which the insulation layer has been stripped is connected to the guide assembly 6, and the bidirectional screw rod 5 is rotated by the handwheel 501, so that the two guide assemblies 6 on it move relative to each other, so that the connecting ends of the two cables are inserted into the connecting sleeve for crimping. The two guide assemblies 6 can limit and fix the cables during the crimping process, thereby achieving a better crimping effect.

[0031] The guide assembly 6 comprises a sliding block 601, an upper pressing seat 603, and a limiting block 602. The sliding block 601 is slidably connected to the second slide groove 101 via the limiting blocks 602 on both sides and is threadedly connected to the bidirectional screw rod 5.

The guide post 606 is installed in the guide cylinder 605. The mutual cooperation between the guide post 606 and the guide cylinder 605 limits the position of the sliding block 601 and the upper pressure seat 603 to avoid misalignment during the process of fixing the cable.

[0033] The stripping assembly 7 also includes a contact plate 302, which is installed on the support frame 3 and is located directly behind the wire pay-out seat 701. The cable is inserted into the placement groove opened on the wire pay-out seat 701 until the front end of the cable contacts the contact plate 302, and then the knife seat 703 is pressed down to strip the insulation layer. Through the setting of the contact plate 302, the stripping lengths of the two cables can be kept at the same length, without the need to use an additional stripping device, thereby improving work efficiency.

[0034] A rotating rod 405 is installed on the upper end of the screw rod 404 .

[0035] When used specifically:

[0036] When two cables need to be crimped, the insulation layers of the two cable connection ends are firstly stripped by the wire stripping assembly 7. At the same time, the contact plate 302 provided can make the stripped cable lengths basically consistent. After the two cables are stripped, the hand wheel 501 is turned to drive the bidirectional screw rod 5 to rotate, so that the two guide assemblies 6 threadedly connected on the bidirectional screw rod 5 move in opposite directions. After moving a certain distance, the upper pressing seat 603 is pulled upward for a certain distance, and then the stripped connection end of the cable is passed out from between the sliding block 601 and the upper pressing seat 603, and then the upper pressing seat 603 is released at the first spring 6 04 The rebound force compresses and fixes the cable. Similarly, the same operation is performed on the other side to fix the two cables. Then, the connecting sleeve is placed on the pressing platform 2. After the connecting sleeve is placed, the bidirectional screw rod 5 is rotated in the opposite direction to move the two guide components 6 relative to each other, so that the connecting ends of the two cables are inserted into the connecting sleeve. Then, the screw rod 404 is rotated downward by the rotating rod 405, and the lower pressing seat 401 is pushed downward to make the pressing block 403 squeeze the connecting sleeve, thereby squeezing the connecting sleeve and the cable placed inside it into a whole, and the crimping work of the two cables is completed.
