In the prior art, pliers are generally used to clamp the workpieces of automobile parts. For example, the patent with publication number CN220012713U discloses a workpiece clamping device for quenching, including a pliers handle, a parallel clamping installation assembly, a replaceable clamping assembly and a clamping handle assembly. The pliers handle is provided with two, The front ends of the two clamp handles are respectively fixedly connected with scissor rods, the middle parts of the two scissor rods are cross-arranged, and the intersection of the two scissor rods is movably connected through a movable shaft. The parallel clamping installation assembly includes a mounting seat, and the mounting seats are provided with two and correspondingly arranged on the left and right.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] See also Figures 1 to 5 The utility model provides a technical solution: a clamping device for quenching, including a connecting rod 1, a connecting shaft 2 is fixed at one end of the connecting rod 1, a clamping assembly is rotatably matched on the connecting shaft 2, a slider 13 is slidably matched on the connecting rod 1, a first rotating shaft 10 is fixed on the slider 13, a pulling assembly is installed between the first rotating shaft 10 and the clamping assembly, a first handle 15 is fixed at the other end of the connecting rod 1, a second handle 16 is fixed on the lower side of the slider 13, a limiting block 17 is fixed on the connecting rod 1, and a lifting assembly is installed on the lower side of the connecting rod 1.

[0023] In this embodiment, the clamping assembly includes a connecting shaft 2, a first swivel 3, a second swivel 4, a first clamp 5 and a second clamp 6. The first swivel 3 and the second swivel 4 are rotatably connected to the connecting shaft 2, the first clamp 5 is fixedly connected to the first swivel 3, the second swivel 4 is fixedly connected to the second clamp 6, a first extension rod 7 is fixed on the first swivel 3, a second extension rod 8 is fixed on the second swivel 4, a second rotating shaft 11 is fixed on the first extension rod 7 and the second extension rod 8, the pulling assembly is two pull rods 9, one end of the pull rod 9 is rotatably connected to the first rotating shaft 10, and the other end of the pull rod 9 is rotatably connected to the second rotating shaft 11, a sliding groove 12 is opened in the connecting rod 1, the sliding groove 12 corresponds to the slider 13, and a spring 14 is fixed between the slider 13 and the groove wall of the sliding groove 12.

[0024] Specifically, when the accessory needs to be clamped, the first handle 15 and the second handle 16 are manually held to move the second handle 16 toward the first handle 15, thereby driving the slider 13 to slide, so that the slider 13 pulls the pull rod 9 through the first rotating shaft 10, so that the first extension rod 7 and the second extension rod 8 are close to each other, thereby driving the first clamping plate 5 and the second clamping plate 6 to approach each other, thereby clamping the accessory. When quenching is completed, the second handle 16 is released, and the spring 14 rebounds at this time, which can drive the slider 13 to reset, thereby pushing the first extension rod 7 and the second extension rod 8 to rotate, so that the first clamping plate 5 and the second clamping plate 6 can release the accessory.

[0025] The lifting assembly includes a lifting block 18 and a telescopic rod 19. The lifting block 18 is fixedly connected to one end of the telescopic rod 19. The lifting block 18 and the limiting block 17 are both semi-annular structures.

[0026] Specifically, when one end of the clamping assembly is heavier, the lifting block 18 can be manually clamped on the connecting rod 1 through the telescopic rod 19. At this time, the limit block 17 limits the lifting block 18, and the end of the connecting rod 1 with the clamping assembly can be lifted upward through the telescopic rod 19 and the lifting block 18, thereby preventing the device from tilting and causing the accessories to fall.

[0027] A baffle 20 is fixed on the connecting rod 1 to prevent the high temperature emitted by the accessories from damaging the hands holding the first handle 15 and the second handle 16 .

[0028] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
