Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of locking pliers, in particular to a combined multifunctional locking pliers. Background Art
[0002] Locking pliers are mainly used to clamp parts for various processing. Commonly used locking pliers control the opening and closing of the pliers through the toggle clamping mechanism, and generate a large clamping force after locking through the tension spring, so that the clamped parts will not loosen, and the jaws have multiple adjustment functions for clamping parts of different thicknesses.
[0003] Patent CN105328596B records a kind of locking pliers with a multi-speed adjustment function. On the basis of ensuring high-strength clamping force, it can clamp parts of different thicknesses and is suitable for a variety of complex processing conditions. However, the opening and closing degree of the locking pliers is limited. The opening and closing degree of the locking pliers is affected by the range of motion of the pliers arm and the crank. It is impossible to clamp parts whose thickness is much greater than the width between the two pliers handles of the locking pliers. Therefore, there are still great limitations in the application process. Utility Model Content
[0004] In order to make up for the above shortcomings, the utility model provides a combined multifunctional locking pliers.
[0005] The utility model is achieved in this way:
[0006] A combined multifunctional locking pliers comprises a locking pliers body and an adjusting mechanism, wherein the locking pliers body comprises a fixed handle and a movable handle, a sliding groove is provided at the top end of the fixed handle, the adjusting mechanism comprises a first threaded rod, and the first threaded rod is rotatably installed in the sliding groove, a first knob is provided on the outer side of the fixed handle, and a connecting rod is connected between the first knob and the first threaded rod, a sliding block is bite-connected on the outer side of the first threaded rod, and the sliding block can slide in the sliding groove, a first movable pliers is provided on the outer side of the fixed handle, the first movable pliers is connected to the sliding block, a second movable pliers is hinged on the top end of the movable handle, and the second movable pliers is hinged to the fixed handle.
[0007] The beneficial effect of adopting the above further scheme is that the first knob is used to drive the first threaded rod to rotate, so that the slider can be moved in the slide groove, thereby driving the first movable clamp to move, thereby changing the distance between it and the second movable clamp. When the pliers reach the maximum opening and closing, if the thickness of the object to be clamped still exceeds the distance between the first movable clamp and the second movable clamp, the position of the first movable clamp can be adjusted so that it and the second movable clamp can clamp the object, thereby improving the functionality of the pliers.
[0008] Furthermore, a first threaded hole is opened on one side of the sliding block, and the first threaded rod is engaged with the first threaded hole.
[0009] Furthermore, an adjusting block is hinged on the inner side of the movable handle, one end of the adjusting block slides inside the fixed handle, and a tension spring is connected between the adjusting block and the second movable clamp.
[0010] Furthermore, a limiting groove is provided inside the fixing handle, limiting blocks are installed on both sides of the adjusting block, and the limiting blocks slide inside the limiting groove.
[0011] Furthermore, a second threaded hole is formed at the end of the fixing handle, and a second threaded rod is engaged and connected inside the second threaded hole, one end of the second threaded rod is connected to a second knob, and the other end of the second threaded rod abuts against one end of the adjustment block.
[0012] The beneficial effect of adopting the above further scheme is that when the second knob is rotated, the second threaded rod can be extended and retracted. Since the adjustment block slides in the fixed handle through the limit block and the limit groove, it will be supported by the second threaded rod and move. Since it is connected to the second movable clamp by a tension spring, the second movable clamp will rotate as a result, further changing the distance between it and the first movable clamp.
[0013] Furthermore, an elastic handle is hinged inside the movable handle, and one end of the elastic handle abuts against the adjustment block.
[0014] The beneficial effect of adopting the above further solution is that after the movable handle and the fixed handle are closed, it may be difficult for the user to separate them. At this time, the elastic handle is pushed to squeeze the adjustment block, so that the movable handle and the fixed handle are automatically separated.
[0015] Furthermore, the outer sides of the first knob and the second knob are both provided with anti-slip grooves.
[0016] The beneficial effect of adopting the above further solution is that the anti-slip pattern can facilitate the user to rotate the first knob and the second knob.
[0017] The beneficial effect of the utility model is as follows: the utility model obtains a combined multifunctional locking pliers through the above design, and utilizes the first knob to drive the first threaded rod to rotate, so that the slider can move in the slide groove, thereby driving the first movable clamp to move, so as to change the distance between the first movable clamp and the second movable clamp. When the locking pliers reach the maximum opening and closing, if the thickness of the object to be clamped still exceeds the distance between the first movable clamp and the second movable clamp, the position of the first movable clamp can be adjusted so that the first movable clamp and the second movable clamp can clamp the object, thereby improving the functionality of the locking pliers.

When the pliers reach the maximum opening and closing, if the thickness of the object to be clamped still exceeds the distance between the first movable clamp 1003 and the second movable clamp 1004, the position of the first movable clamp 1003 can be adjusted to enable it to clamp the object together with the second movable clamp 1004, thereby improving the functionality of the pliers.
[0028] Embodiment 2 of the utility model of a combined multifunctional pliers
[0029] Reference Figure 1-Figure 4Specifically, a first threaded hole 2002 is provided on one side of the slider 2001, and the first threaded rod 2004 is engaged with the first threaded hole 2002. An adjusting block 1007 is hinged on the inner side of the movable handle 1002, and one end of the adjusting block 1007 slides inside the fixed handle 1001. A tension spring 1008 is connected between the adjusting block 1007 and the second movable clamp 1004. A limiting groove 1010 is provided inside the fixed handle 1001, and limiting blocks 1012 are installed on both sides of the adjusting block 1007, and the limiting blocks 1012 slide inside the limiting groove 1010.
