The lower surface of the upper plate 4 is provided with a downwardly protruding pressing tooth 45, and the upper surface of the lower plate 5 is provided with a downwardly concave pressing groove 55, which is used to place cables and copper noses. The rotation of the operating handle 2 can drive the wire pressing seat 3 to move up and down in parallel with the base 1, and make the pressing tooth 45 and the wire pressing groove 55 press together accordingly. By setting a connecting mechanism 6 to connect with the wire pressing seat 3, the pressing operating handle 2 can be pressed down to drive the upper plate 4 of the wire pressing seat 3 to press down in parallel with the lower plate 5 on the base 1 to complete the wire pressing action, which is simple to operate, quick and convenient.

[0030] The lower surface of the wire pressing seat 3 is provided with a first slide groove 41 arranged along the length direction, and the top of the upper plate 4 is provided with a first protruding edge 42 protruding upward, and the first protruding edge 42 can be inserted along the first slide groove 41 and the upper plate 4 is limited to the lower surface of the wire pressing seat 3; the base 1 is provided with a second slide groove 51 arranged along the length direction, and the bottom of the lower plate 5 is provided with a second protruding edge 52 protruding downward, and the second protruding edge 52 can be inserted along the second slide groove 51 and the lower plate 5 is limited to the base 1; one end of the wire pressing seat 3 is provided with a first locking piece 43 protruding outward, and one end of the upper plate 4 is provided with a first protruding outward. Locking seat 44, when the upper plate 4 is inserted into the first slide groove 41 through the first protruding edge 42, the first locking piece 43 and the first locking seat 44 are correspondingly arranged up and down, and are locked on the first locking seat 44 by setting a bolt passing through the first locking piece 43; one end of the lower plate 5 is provided with a second locking piece 53 protruding outward, and one end of the base 1 is provided with a second locking seat 54 protruding outward, when the lower plate 5 is inserted into the second slide groove 51 through the second protruding edge 52, the second locking piece 53 and the second locking seat 54 are correspondingly arranged up and down, and are locked on the second locking seat 54 by setting a bolt passing through the second locking piece 53. The installation of the upper plate 4 and the lower plate 5 is facilitated by arranging the structure of the slide groove (the first slide groove 41, the second slide groove 51) and the protruding edge (the first protruding edge 42, the second protruding edge 52), and the locking plate and the locking seat are arranged to fix the upper plate 4 and the lower plate 5 to prevent them from slipping during use; the upper plate 4 and the lower plate 5 are detachable, so that the upper plate 4 and the lower plate 5 can be replaced according to the specifications of the cable, and the crimping operation of cables of different specifications can be adapted by means of crimping teeth 45 and crimping grooves 55 of different specifications, so that the crimping pliers have a wider range of applications.

[0031] The connecting mechanism 6 includes a connecting plate 61, a first rotating shaft 62, and a second rotating shaft 63. The first rotating shaft 62 is arranged through the operating handle 2. The top of the wire pressing seat 3 is provided with two spaced mounting blocks 64. The second rotating shaft 63 is mounted on the two mounting blocks 64. The connecting plate 61 is provided with two pieces. The two connecting plates 61 are respectively arranged on both sides of the operating handle 2, and the upper end of each connecting plate 61 is rotatably connected to the first rotating shaft 62, and the lower end of each connecting plate 61 is rotatably connected to the second rotating shaft 63. The two ends of the connecting plate 61 can be rotatably arranged, and one end is connected to the wire pressing seat 3. Due to the cooperation of the square guide block 31 and the square hole 111, the wire pressing seat 3 will not be found to rotate, and the parallel working position of the wire pressing seat 3 can be changed by pulling and pressing down the operating handle 2.

[0032] A baffle 7 is provided on one side of the lower plate 5, and the baffle 7 extends outward and vertically upward to the top of the crimping groove 55, and a gap is set between the end of the crimping groove 55 and one side of the baffle 7. Before crimping, the copper nose needs to be placed in the crimping groove 55, and the copper nose is placed at the end of the crimping groove 55, and one end of the copper nose is against the baffle 7, which can effectively prevent the copper nose from being offset when the cable is inserted into the copper nose or during the crimping operation.

[0033] A long plate 8 protruding outward is provided on one side of the lower end of the base 1. The long plate 8 is provided with a plurality of limiters 81. The limiters 81 are used to fix the cable, and one limiter 81 is provided corresponding to one wire pressing groove 55. The limiter 81 includes a cushion block 811 and a spring sheet 812. The cushion block 811 is fixedly provided. Two spring sheets 812 are provided and are spaced apart. The cable can overcome the elastic force of the spring sheet 812 and be clamped between the two spring sheets 812. The function of providing the limiter 81 is to limit the cable so that the cable can be limited one by one corresponding to the wire pressing groove 55, which can prevent the cable from running off or being messy.

[0034] The working principle of this improved bench crimping pliers is as follows:

[0035] Preparation for wire pressing: first select the upper plate 4 and the lower plate 5 that are suitable according to the diameter of the cable to be pressed, then insert the first protruding edge 42 of the upper plate 4 into the first slide groove 41 and lock it with the first locking seat 44 through the first locking piece 43, insert the second protruding edge 52 of the lower plate 5 into the second slide groove 51 and lock it with the second locking seat 54 through the second locking piece 53, and make the pressing teeth 45 of the upper plate 4 and the wire pressing groove 55 of the lower plate 5 correspond to each other;

[0036] During the wire crimping process, the copper noses are placed in the wire crimping groove 55 in sequence and one end of the copper nose is placed against the baffle 7. The cable connectors to be crimped are then inserted into the copper noses along the wire crimping groove 55 in sequence, and the middle section of the cable is pressed between the two spring sheets 812 to overcome the elastic force of the spring sheets 812. The operating handle 2 is then pressed downward, and the operating handle 2 moves downward and pushes the wire crimping seat 3 to move downward parallel to the lower plate 5. When the wire crimping seat 3 moves downward until the pressing teeth 45 of the upper plate 4 contact the copper nose, continue to press downward with force, so that the copper nose is wrapped and pressed tightly with the cable connector, thereby completing the operation of crimping multiple cables at the same time.

[0037] The above is only a specific implementation of the present utility model, but the design concept of the present utility model is not limited to this. Any non-substantial changes to the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
