[0006] Preferably, one side of the opposite surface of the clamping plate is an arc-shaped structure, which is used to make the clamping plate suitable for cables of different specifications, and the clamping plates are symmetrically distributed around the transmission rod, which is used to ensure that the clamping plates synchronously fit the outer surface of the cable.

[0007] Preferably, an adjustment handle is provided at one end of the transmission rod, and the adjustment handle is located outside the movable frame and the fixed frame, and is used to facilitate the user to adjust the spacing between the clamping plates.

[0008] Preferably, the limiting assembly includes a connecting rod, which is located inside grooves opened on both sides of the hydraulic chamber, and a movable plate and a fixed plate are sequentially arranged on the outer surface of the connecting rod. A return spring is arranged between the movable plate and the opposite surface of the hydraulic chamber, and the return spring is sleeved on the outer surface of the connecting rod.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model is further described in detail below based on the drawings and embodiments.

[0023] Example

[0024] Please refer to Figures 1 to 5 As shown, in order to solve the problems mentioned in the technical solution, the embodiment of the present application provides an adjustable hardware hydraulic pliers, including a hydraulic chamber 1, and a pushing structure is arranged in the hydraulic chamber 1, which is used to push the movable frame 5 and the fixed frame 13 closer together, and prompt the clamping plates 8 arranged on the two to crimp the cable together; a pressure rod 2 is arranged on one side of the hydraulic chamber 1, which is used to control the extension of the pushing structure inside the hydraulic chamber 1; an adjusting knob 4 is arranged on the outer surface of the hydraulic chamber 1, which is used to control the reset of the pushing structure inside the hydraulic chamber 1; a blocking rod 3 is arranged at the front end of the hydraulic chamber 1, which is used to limit the movement of the fixed frame 13, and the inner surface of the front end of the hydraulic chamber 1 is evenly provided with mounting grooves 18. A movable frame 5 and a fixed frame 13 are sequentially arranged inside the installation groove 18. The side of the fixed frame 13 away from the movable frame 5 is in contact with the outer surface of the blocking rod 3. A bidirectional lead screw 6 and a limit rod 7 are arranged inside the movable frame 5 and the fixed frame 13. A clamping plate 8 is arranged on the outer surfaces of the bidirectional lead screw 6 and the limit rod 7. A worm gear 9 is arranged in the middle of the outer surface of the bidirectional lead screw 6. A transmission rod 10 is arranged inside the movable frame 5 and the fixed frame 13. A worm 11 is arranged in the middle of the outer surface of the transmission rod 10. The worm 11 is meshed with the worm gear 9. Limiting components are arranged on both sides of the hydraulic chamber 1 through the grooves opened, which are used to assist and fix the cable to be processed.

[0025] It should be noted that one side of the opposite surface of the clamping plate 8 is an arc-shaped structure, which is used to make the clamping plate 8 suitable for cables of different specifications, thereby improving the practicability of the hydraulic pliers; and the clamping plates 8 are symmetrically distributed with the transmission rod 10 as the center, which is used to ensure that the clamping plates 8 synchronously fit the outer surface of the cable, and prevent the clamping plates 8 from not synchronously contacting the outer surface of the cable and causing the cable to slip during the crimping process; at the same time, an adjustment handle 12 is provided at one end of the transmission rod 10, and the adjustment handle 12 is located outside the movable frame 5 and the fixed frame 13, which is used to facilitate the user to adjust the spacing between the clamping plates 8.

[0026] Further examples:

[0027] Please refer to Figures 1 to 5 As shown, the limit assembly includes a connecting rod 14, which is located inside the grooves opened on both sides of the hydraulic chamber 1, and a movable plate 15 and a fixed plate 16 are sequentially arranged on the outer surface of the connecting rod 14, and a return spring 17 is arranged between the opposite surfaces of the movable plate 15 and the hydraulic chamber 1, and the return spring 17 is sleeved on the outer surface of the connecting rod 14, which is used to ensure that the movable plate 15 and the fixed plate 16 always fit the two sides of the cable to be crimped; at the same time, the opposite surfaces of the movable plate 15 and the fixed plate 16 are provided with arc-shaped convex plates, which are used to facilitate and stabilize the cable to be processed, and the fixed plate 16 and the fixed frame 13 are located on the same vertical plane, which is used to ensure that the cable is in a straight state, thereby avoiding shaking during the crimping process and resulting in a poor crimping effect.

[0028] Everything in the above example works like this:

[0029] When in use, the user first adjusts the spacing of the clamping plates 8 according to the diameter of the cable to be crimped, and then the user turns the adjusting handle 12, causing the worm 11 on the connecting rod 14 to drive the worm wheel 9 meshing with it to rotate, and then the worm wheel 9 drives the bidirectional lead screw 6 to rotate, and causes the two clamping plates 8 on the bidirectional lead screw 6 to move relative to each other along the axial direction of the limit rod 7 until it is adjusted to the length of the cable diameter to be crimped and stops, thereby being able to quickly adjust the size of the crimping interface to adapt to cables of different specifications, so that the user does not need to spend a lot of time manually changing the mold, thereby greatly shortening the preparation time and improving the work efficiency, while also reducing the frequency of mold replacement, which can effectively reduce the risk of mold damage and loss, thereby further reducing the cost of use; then pull the movable plate 15 on one side of the hydraulic chamber 1 to cause the movable plate 15 to be fixed The plates 16 are separated from each other, and the reset spring 17 is contracted. Then, one end of the cable to be crimped is passed through between the movable plate 15 and the fixed plate 16 set on one side of the hydraulic chamber 1 and extended into the hydraulic chamber 1. Similarly, the same steps are followed as above to cause the movable plate 15 on the other side of the hydraulic chamber 1 to separate from the fixed plate 16. Then, the portion of the cable to be crimped is aligned with the clamping plate 8, and the movable plate 15 is released at the same time. The elastic action of the reset spring 17 pushes the movable plate 15 to slide axially along the connecting rod 14, and the movable range of the cable is limited by the fixed plate 16 and the limiting convex plates on the movable plate 15, thereby avoiding the situation where the cable shakes during the crimping process and causes a poor crimping effect, and making the crimping process more stable, thereby improving the quality of crimping and ensuring the stability and safety of the cable connection.
