Abstract

The invention discloses a handheld woodworking expander. The handheld woodworking expander is characterized by comprising a pair of rotatable handles and a pair of rotatable clamping arms. The handheld woodworking expander has the advantages that when the handheld woodworking expander is in use, a user directly holds the handles to enable the same to inward move at the same time, and the clamping arms outward move at the same time through cooperation of top-pressing protrusions and handle clamping pieces to enable an expanding disc of an expanding rod to be abutted against a woodworking member needing to be machined; the user can adjust position of the expanding rod in an arm tube according to actual needs, so that the handheld woodworking expander is high in flexibility, convenient to operate, convenient and quick to adjust and high in practicability and great convenience is brought to woodworking.

Description

Hand-held type carpenter's expander

Technical Field

The invention relates to a woodworking tool, in particular to a handheld woodworking expander.

Background

In the woodworking process, a wooden workpiece is often required to be expanded and fixed. The existing method utilizes two independent clamps, the distance between the clamps is easy to change due to the sliding of the clamps, and the processing precision of a workpiece is influenced.

Disclosure of Invention

The invention mainly solves the technical problems in the prior art, and provides a handheld woodworking expander.

The technical problem of the invention is mainly solved by the following technical scheme:

a handheld woodworking expander is characterized by comprising a pair of rotatable handles and a pair of rotatable clamping arms, wherein each handle comprises an arc-shaped handle main body, a flat handle clamping piece is arranged at the head of each handle main body, a first connecting round hole and a second connecting round hole are formed in each handle clamping piece, each clamping arm comprises an arc-shaped arm strip, a third connecting round hole and a fourth connecting round hole are formed in the tail of each arm strip, a tubular arm tube is arranged at the head of each arm strip, a detachable expansion rod is arranged in each arm tube and comprises an expansion screw rod, an expansion disc is arranged at the head of each expansion screw rod, a movable positioning nut is arranged on each expansion screw rod, a first screw penetrates through each second connecting round hole, a second screw penetrates through each first connecting round hole and each fourth connecting round hole, and a third screw penetrates through the third connecting round hole respectively, the outer wall of the third connecting round hole is provided with a jacking protrusion protruding inwards, and the jacking protrusion is matched with the handle clamping piece.

As a preferred embodiment of the invention, the expansion rod is made of stainless steel.

The handheld woodworking expander has the following advantages: during the use, the user directly grips the handle for the handle is simultaneously to the internalization, and under the cooperation of the outstanding and handle clamping piece of roof pressure, the arm lock is simultaneously to the outsourcing activity, makes the expansion disc of expansion pole support the wooden work piece that needs processing, and the user can adjust the position of expansion pole in the arm pipe according to actual need, and the flexibility is good, convenient operation, and it is convenient to adjust, has made things convenient for carpenter's processing greatly, and the practicality is strong.
