[0029] Embodiment 1:

[0030] like Figure 1 , Figure 2 As shown, a tool pliers which is convenient for replacing the corresponding adapter chuck 3 includes:

[0031] A handle 1, a jaw 2 is provided at the end of the handle 1, and a groove 1 is provided on the jaw 2; a limit member 4, the limit member 4 is located in the groove 1, and a protrusion 401 is provided at the end of the limit member 4; a chuck 3, a groove 2 is provided on the chuck 3, and the groove 2 is adapted to the shape of the protrusion 401; a support member 5, the support member 5 is movable in the groove 1, and is located on one side of the limit member 4, and is used to abut the chuck 3, and a stop member 6 is provided in the middle of the support member 5, and the posture of the support member 5 is limited by abutting the limit member 4.

[0032] On the basis of the original tool pliers, a groove 1 is left on the pliers mouth 2, a limit piece 4 is set in the groove 1, and a support piece 5 is movably set at the bottom of the groove 1, wherein the support piece 5 is used to resist the chuck 3, wherein a stop piece 6 is also set on the support piece 5, which is used to resist the limit piece 4, so as to prevent the support piece 5 from shaking left and right and loosening when the chuck 3 is locked, a protrusion 401 is set at the end of the limit piece 4, and a corresponding groove 2 is set on the chuck 3, so as to cooperate with the support piece 5 to lock the chuck 3, and the chuck 3 can be quickly locked or quickly loosened by adjusting the support piece 5 to be updated and replaced, so that the pliers mouth 2 can be easily replaced with the corresponding adapter chuck 3, thereby solving the problem that the tool pliers need to replace the corresponding adapter chuck 3.

[0033] Specifically, in order to enable the support member 5 to be movably arranged in the groove 1 and to facilitate the placement and removal of the chuck 3 by swinging left and right to a limited extent, a receiving groove is arranged at the bottom of the groove 1, and a protrusion 2 is arranged at the bottom of the support member 5. The protrusion 2 is located in the receiving groove and is used to enable the support member 5 to swing left and right within a predetermined range.

[0034] Specifically, in order to limit the movement of the support member 5 and increase the stability of the swinging of the support member 5, the support member 5 is selected to be eccentrically arranged, the receiving groove and the protrusion 2 are arc-shaped, the pliers mouth 2 is provided with a through hole 1, which is located below the center of the arc-shaped shape of the receiving groove, and the protrusion 2 is provided with a through hole 2, which is located at the center of the arc-shaped shape of the protrusion 2. By passing the pin through the through hole 1 and the through hole 2, the protrusion 2 is connected to the receiving groove through the pin, thereby completing the eccentric connection of the protrusion 2, thereby increasing the stability of the support member 5 while ensuring that the support member 5 can only perform limited activities.

[0035] Specifically, a plurality of oblique teeth 402 are provided in the middle of the limit member 4, and the stop member 6 is used to abut against the oblique teeth 402 to limit the inward rotation of the support member 5. The stop member 6 includes a pawl. The limit member 4 is arranged in an arc shape on the inner side and extends toward a center direction of the groove. By arranging the pawl, the support member 5 can only perform one-way intermittent movement, thereby preventing the chuck 3 from loosening during use, and ensuring that the chuck 3 can be easily replaced and used normally.

[0036] Specifically, in order to further lock the chuck 3, a bolt 501 is provided on the support member 5, which is threadedly connected to the support member 5. A supporting portion is provided on the bolt 501, which is used to make the supporting portion contact the chuck 3, and cooperate with the limit member 4 and the stop member 6 to lock the chuck 3. The shape of one side of the chuck 3 is adapted to the arc shape of the limit member 4. A protrusion 301 is provided on the chuck 3, which is adapted to the shape of the opening on the clamped workpiece, so that the support member 5 can further stably lock the chuck 3.

[0037] Although the above describes the illustrative specific implementation methods of the present application so that technicians in this technical field can understand the present application, the present application is not limited to the scope of the specific implementation methods. For ordinary technicians in this technical field, as long as various changes are within the spirit and scope of the present application defined and determined by the attached claims, all application creations using the concept of the present application are protected.
