Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of flat-nose pliers, specifically to a valve block anti-floating flat-nose pliers. BACKGROUND

[0002] Flat-nose pliers, also known as machine vices, are general-purpose clamps commonly used for installing small workpieces. They are random accessories of milling machines and drilling machines, which are fixed on the machine tool workbench to clamp workpieces for cutting processing.

[0003] The patent document with publication number CN221474838U discloses a valve block anti-floating flat-nose pliers. To address the problem of the valve block easily moving upward and inconvenient angle adjustment, the following solution is proposed. It includes a pliers body, a fixed jaw is welded to the top outer wall of the pliers body, and a lifting block is connected to the inner wall of the fixed jaw. A lifting screw is screwed to the outer wall of one side of the lifting block. The height of the anti-floating pressure plate is adjusted by turning the lifting screw. The anti-floating pressure plate is fixed by turning the tightening screw, so that it can be tightly pressed above the valve block, avoiding the problem of the valve block floating upward, improving the overall stability of the flat-nose pliers, and the pliers body can rotate along the axis of the pliers seat hinge, so that the processing angle of the valve block can be quickly changed. The positioning groove plate can be fixed by rotating the tightening screw, preventing the pliers body from shaking, making the operation convenient and stable, greatly improving the convenience of valve block processing. However, the patent still has the following problems in actual use:

[0004] The flat-nose pliers achieve the anti-floating effect of the valve block by setting the anti-floating pressure plate and cooperating with the tightening screw. However, when using the flat-nose pliers, the worker still needs to hold the valve block for clamping. When the valve block is placed, it is difficult to control the supporting force when the valve block is in contact with the bottom surface of the anti-floating pressure plate, which may cause deformation of the anti-floating pressure plate or the valve block to tilt and float. Moreover, the tightening of the tightening screw makes the use of the flat-nose pliers inconvenient, thus reducing the practicality of the anti-floating flat-nose pliers.
