Description

Technical Field

The bidirectional screw passes through the workbench and extends to the outside of the workbench. The clamping plate is threadedly connected to the bidirectional screw, and a handle is welded at one end of the bidirectional screw. A fixing groove is opened at the front end of the outer wall of the clamping plate. Adapted to the production and application in the field of sealing strip technology, the sealing strip clamp that is easy to cut is conducive to fixing sealing strips of different sizes by providing bidirectional screws, clamping plates, fixing plates, upper clamping blocks, fixing blocks, first extension blocks, lower clamping blocks, second extension blocks, etc. The sealing strip is fixed to the workbench while the cut surface of the sealing strip is fixed to the upper clamping block and the lower clamping block. The fixing method is simple and quick, and the cut surface of the sealing strip is smooth after cutting, which is conducive to the splicing of the sealing strip.

[0004] When the above-mentioned sealing strip clamp is in use, the sealing strip itself has a certain elasticity, so that the sealing strip is prone to bounce up and down during the processing, affecting the smooth progress of the processing operation. In addition, since the sealing strip itself is relatively soft, it is easy to be inconvenient to clamp when fixed, and the position of the sealing strip needs to be repeatedly adjusted, affecting the efficiency of the fixing and clamping operation. Therefore, in view of the above problems, an automotive EPDM sealing strip fixing clamp is proposed. Utility Model Content
