In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0027] As Figures 1 to 2As shown in the figure, the linkage-adjustable wire pressing pliers include a first wire pressing pliers head 1, a second wire pressing pliers head 2 and a handle 3. A fixing nut 4 is arranged on the first wire pressing pliers head 1 and is fixedly connected to the second wire pressing pliers head 2 through a fixing plate 401. The first wire pressing pliers head 1 and the handle 3 are connected through a fixing bolt 5. The rear ends of the first wire pressing pliers head 1 and the second wire pressing pliers head 2 are connected through a connecting rotating shaft 6. During the relative rotation of the first wire pressing pliers head 1 and the second wire pressing pliers head 2, the connecting rotating shaft 6 realizes the movement constraint, allowing the first wire pressing pliers head 1 and the second wire pressing pliers head 2 to move relative to each other, but they are connected at a node. An adjusting knob 7 is arranged on the first wire pressing pliers head 1. A synchronous gear set 8 is arranged inside the adjusting knob 7. The wire pressing space between the first wire pressing pliers mouth 1 and the second wire pressing pliers mouth 2 is adjusted by rotating the adjusting knob 7. The specific process is as follows by Figure 3 and Figure 4 it can be seen that when the adjusting button 7 is rotated, the adjusting button 7 and the first rotating tooth 801 are jointly connected through a rotating shaft. A hexagonal nut 8011 is arranged at the central position of the first rotating tooth 801. The hexagonal nut 8011 is fixedly connected to the second rotating tooth 802. The first rotating tooth 801 and the second rotating tooth 802 are coaxially connected. The second rotating tooth 802 and the fixed rotating tooth 803 are rotatably connected between the two gears. Also, because the gear structures inside the first wire pressing pliers head 1 and the second wire pressing pliers head 2 are symmetrically distributed designs, by rotating the adjusting button 7 to drive the first rotating tooth 801 and the second rotating tooth 802, and driving the fixed rotating tooth 803 through the second rotating tooth 802. Due to the relationship of the symmetrically distributed design, the rotation of the internal gear of the second wire pressing pliers head is driven, thus realizing the adjustment of the internal pliers mouth space of the linkage-adjustable wire pressing pliers. It should be noted that in Figure 4 it can be observed that the teeth on the first rotating tooth 801 are of unequal length design, which to a certain extent improves the adaptability of the wire pressing pliers to the caliber size of the wire to be pressed. The rapid adjustment of the wire pressing space of the entire wire pressing pliers mouth can be realized through a single adjusting button 7. The wire is placed in the gap of the first rotating tooth 801, and the handle 3 is pressed. At this time, the entire first rotating tooth 801 moves upward. An elastic constraint is exerted on the entire synchronous gear set 8 through a limiting plate 1003. When the handle 3 is released, at this time, due to the action of the spring 1002, the limiting plate 1003 exerts a certain degree of resetting action on the synchronous gear set 8, so that the entire linkage-adjustable wire pressing pliers have a better use experience during the use process.

[0028] In the description of the present utility model, it should be noted that unless otherwise clearly defined and limited, the terms "installed", "connected", and "coupled" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
