DETAILED DESCRIPTION

[0019] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] In this embodiment, refer to Figure 1-Figure 4 The invention specifically implements a flat-nose pliers which is easy to position, comprising a positioning assembly 1, a fixed pliers body 2 and a movable pliers body 3 which slides with the fixed pliers body 2. The positioning assembly 1 comprises a sliding shaft 4 which is installed on one side of the fixed pliers body 2, the sliding shaft 4 is provided with a movable and rotatable sliding block 5, the sliding block 5 is provided with a slidable and rotatable clamping block 6, and the clamping block 6 is provided with a slidable positioning rod 7.

[0021] Furthermore, the sliding shaft 4 is fixed to the fixed pliers body 2 by means of threads. By adjusting the positions of the sliding block 5 and the clamping block 6, the positioning rod 7 can be moved to any position as a positioning reference for the part. When the side of the part is an inclined surface, the positioning rod 7 can be made parallel to the inclined surface by adjusting the angle of the clamping block 6. Even if the size of the part is larger than the width of the flat-nose pliers, it can be adjusted by moving the sliding block 5 on the sliding shaft 4. The positioning requirements of different parts can also be met by replacing the positioning rod 7.

[0022] Furthermore, the sliding block 5 and the clamping block 6 are respectively provided with a limiting hole 8 and a limiting groove 9, and the limiting hole 8 is slidably matched with the limiting groove 9 through the first fixing member 10. This makes the clamping block 6 more stable when it fits the sliding block 5, and is not prone to displacement or shaking, thereby improving the accuracy and reliability of positioning.

[0023] Furthermore, the sliding block 5 is provided with a clamping groove 11 which is fastened with the first fixing member 10. The first fixing member 10 fixes the clamping block 6 on the sliding block 5 and fixes the position of the sliding block 5 on the sliding shaft 4 at the same time. The sliding block 5 and the clamping block 6 are double fixed, and the steps required for fixing are reduced.

[0024] Furthermore, a locking groove 12 is provided at one end of the clamping block 6, and the locking groove 12 is fastened with the positioning rod 7 through the second fixing member 13. The position of the positioning rod 7 is firmly fixed to avoid deviation during the processing and affect the accuracy of positioning.

[0025] Furthermore, the fixed jaw body 2 and the movable jaw body 3 are respectively provided with a first step groove 14 and a second step groove 15 for matching each other. The corresponding shapes of the first step groove 14 and the second step groove 15 enable the flat-nose pliers to clamp parts of different heights, increasing the processing range of parts without the need for additional shims and other items.

[0026] Furthermore, a mounting groove 16 is provided in the fixed pliers body 2, and the mounting groove 16 is slidably matched with the movable pliers body 3 through a screw rod 17. The screw rod 17 is installed in the mounting groove 16 by a bearing, so that the screw rod 17 can only rotate in situ in the mounting groove 16. One end of the movable pliers body 3 is inserted into the mounting groove 16, and the self-locking nut cooperates with the screw rod 17, so that the movable pliers body 3 is restricted by the screw rod 17 to slide in the mounting groove 16. After the screw rod 17 stops rotating, the self-locking nut fixes the movable pliers body 35 by friction, thereby achieving the effect of clamping and loosening parts.

[0027] Furthermore, one end of the screw rod 17 is provided with a handle interface 18 protruding from the fixed pliers body 2. When installing or removing parts, the handle is inserted into the handle interface 18 and rotated to achieve the effect of clamping and loosening the parts. The handle can be directly removed before processing, saving the space occupied by the flat-nose pliers. This allows more flat-nose pliers to be installed for processing.

[0028] The beneficial effects of the utility model are as follows: through the sliding shaft 4 installed on one side of the fixed pliers body 2, the sliding shaft 4 is installed with a movable and rotatable sliding block 5, the sliding block 5 is installed with a slidable and rotatable clamping block 6, and the clamping block 6 is installed with a slidable positioning rod 7. In the process of mass production, the position can be adjusted according to the size and shape of different parts as a positioning reference. Thus, the effect of rapid positioning is achieved. Thus, the convenience and practicality of the flat-nose pliers are improved.
