Description

Technical Field

[0001] This utility model relates to the field of manual hardware tools, specifically a multi-presser foot pliers. Background Technology

[0002] Currently, common C-type bolt clamps on the market include an A-foot, a B-foot, a fixed arm, a movable arm, a fixed handle, a movable handle, an adjusting screw, a tension spring, a support plate, a hinge, and rivets. The A-foot connects to the fixed arm, the B-foot connects to the movable arm, the fixed arm connects to the fixed handle, the hinge connects to the movable handle, the support plate connects to the movable handle, the movable arm connects to the fixed handle, and the movable arm connects to the movable handle. The fixed handle has an adjusting screw at its end, and the tension spring connects the movable arm to the fixed handle at both ends. When clamping objects, it can only clamp flat objects and can only apply a force perpendicular to the clamped plane, resulting in a less than secure clamping effect. Summary of the Invention

[0003] The purpose of this invention is to solve the problem that ordinary C-type bolt clamps cannot clamp round tubes and cannot firmly clamp square tubes, and to provide a multi-presser bolt clamp that is reasonably designed, easy to manufacture, and can more firmly clamp square and round tubes. The technical solution adopted by this utility model to solve its technical problem is: a multi-presser foot pliers, including an A presser foot, a B presser foot, a V-shaped presser foot, a pin, a fixed arm, a movable arm, a rivet, a fixed handle, a movable handle, an adjusting screw, an internal hex screw, a tension spring, a support plate, a lifting plate, and pads, etc. The A presser foot is connected to the fixed arm, the B presser foot is connected to the fixed arm, the fixed arm is connected to the fixed handle, the A pad and the B pad are placed between the V-shaped presser foot and the movable arm, the V-shaped presser foot is connected to the movable arm, the movable arm is connected to the movable handle, the lifting plate is connected to the movable handle, the support plate is connected to the movable handle, the movable arm is connected to the fixed handle, an adjusting screw is installed at the tail of the fixed handle, and the two ends of the tension spring are connected to the movable arm and the fixed handle. The fixed arm has an A presser foot and a B presser foot, and the movable arm has a V-shaped presser foot. The A presser foot is connected to the fixed arm by an A rivet, the B presser foot is connected to the fixed arm by a B rivet, and the V-shaped presser foot is connected to the movable arm by an internal hex screw. The three presser feet can achieve a more secure clamping of square tubes and round tubes.

[0004] In summary, this utility model provides a multi-foot clamping pliers that is reasonably designed, easy to manufacture, and can more firmly clamp square and round tubes. Attached Figure Description
