Novel F-shaped hand screw clamp

Abstract

The invention provides a novel F-shaped hand screw clamp. The novel F-shaped hand screw clamp comprises a guiding rod, a fixed arm, a movable arm, a locking screw rod and a locking handle, wherein the fixed arm is fixed at one end of the guiding rod, and a pressing table is arranged at the end part of the fixed arm; a sleeve hole is formed in one end of the movable arm, the movable arm is mounted on the guiding rod in a sleeving manner through the sleeve hole, and a locking hole is formed in the other end of the movable arm; a U-shaped groove is formed in one end of the locking screw rod, the locking handle is movably hinged to a position in the U-shaped groove through a pin shaft, a rubber pad coats the outer side of the locking handle, and the other end of the locking screw rod penetrates through the locking hole and is matched with the pressing table; V-shaped skid-proof teeth are arranged on the lateral wall of one side of the guiding rod, and inner teeth matched with the skid-proof teeth are arranged in the sleeve hole. The novel F-shaped hand screw clamp disclosed by the invention has the advantages of simple structure, convenience in operation, good practicality and sliding resistance.

Description

technical field [0001] The invention relates to the technical field of auxiliary tools, in particular to a novel F-type woodworking clamp. Background technique [0002] F-type carpentry clamp is a necessary tool for woodworking. It has a simple structure and is dexterous to use. It is a good helper for carpentry. The working principle of the F-type woodworking clamp is: slide the movable arm by hand. When sliding, the movable arm must be kept parallel to the guide rod, otherwise it will not slide. When sliding to the width of the workpiece, the workpiece can be placed between the two force arms. Then slowly rotate the screw bolt on the movable arm to clamp the workpiece, adjust to the appropriate tightness and let go to complete the workpiece fixation. There is a bayonet on the guide rod, which can prevent the guide rod from slipping and ensure that it will not loosen when clamping the workpiece. There is a block on each of the two force arms, which can prevent the workpiec...

AI Technical Summary

Problems solved by technology

The existing F-clamp guide rods are all smooth. When locking, you need to hold the movable arm with your hand to lock it, otherwise it will be offset, and the movable arm is easy to slide during use; and the current locking handles are all 1-shaped, it requires a lot of force to lock the workpiece, and it is easy to slide when rotating, which is inconvenient to operate
