DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0017] See also Figure 1-2 The utility model provides a technical solution: a hardware tool pliers, including a pliers mouth 1, one end of the pliers mouth 1 is provided with a pliers jaw 2, one end of the pliers jaw 2 is fixedly connected to a connecting rod 3, one end of the connecting rod 3 is sleeved with a handle 4, the surface of the pliers jaw 2 on one side is fixedly connected to a fixing block 5, a limiting groove 6 is fixedly provided on the surface of the fixing block 5, and a locking screw 7 is threadedly connected to the surface of the pliers jaw 2 on the other side, and the locking screw 7 is slidably sleeved in the inside of the limiting groove 6.

[0018] In the present embodiment, when the handle 4 is held and rotated, the pliers mouth 1 can be driven to clamp and fix the object. At this time, during the clamping process, the locking screw 7 can slide inside the limit groove 6. After clamping, the locking screw 7 is turned to lock and fix the fixing block 5, so that the pliers mouth 1 can be fixed. This design method can lock the opening size of the pliers mouth 1, so that it can be locked during clamping, and the locked state does not need to be maintained manually, which is easier and more labor-saving.

[0019] Specifically, a fixing ear 8 is fixedly connected to the inner side of the handle 4 , and a tension spring 9 is clipped and sleeved on one end of the fixing ear 8 .

[0020] In this embodiment, by providing the tension spring 9, the original clamping size can be directly restored after the clamping is released, which is beneficial for the next clamping.

[0021] Specifically, a rubber protective pad 15 is fixedly connected to the inner side of one end of the pliers mouth 1 , and a jaw 16 is fixedly opened at the other end of the pliers mouth 1 .

[0022] In this embodiment, the rubber protective pad 15 can play a certain protective role, and after the rubber protective pad 15 is deformed, the friction force can be increased to facilitate clamping and fixing. The jaws 16 can be used to clamp and fix some angular objects, and the jaws 16 can be fixed to achieve a good fixing effect.

[0023] Specifically, a limiting block 11 is fixedly connected to the surface of the connecting rod 3 , and the connecting rod 3 is limitedly sleeved inside the handle 4 .

[0024] In this embodiment, the limiting block 11 is provided to limit the connection rod 3 so that it can only slide inside the handle 4 but cannot rotate.

[0025] Specifically, a gripping tooth groove 10 is fixedly provided on the outer surface of the grip 4, one end of the grip 4 is rotatably connected to a rotating handle 12, a rotating tooth mouth 13 is fixedly provided on the outer surface of the rotating handle 12, one end of the rotating handle 12 is fixedly connected to a threaded rod 14, and the threaded rod 14 is threadedly sleeved inside the connecting rod 3.

[0026] In this embodiment, the rotating handle 12 can drive the threaded rod 14 to rotate threadedly when it is manually rotated. After the threaded rod 14 is rotated, it can rotate threadedly with the connecting rod 3. Since the connecting rod 3 and the handle 4 can only slide, the rotating handle 12 can drive the handle 4 to slide threadedly on the surface of the connecting rod 3 after it is rotated, so that the length of the handle 4 can be changed, which can meet different usage requirements and is more convenient to use.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
