Abstract

The invention discloses a universal base of a scroll saw. The universal base of the scroll saw comprises a rectangular base plate, a rotational round hole is formed in the center of the base plate, a pair of clamping protrusions is arranged on the head of the substrate, and a pair of upwards-swelling clamping arc strips and a downwards-bending clamping flange are arranged at the tail of the base plate. The universal base of the scroll saw has the advantages that a user can adjust the angle of a complete machine body at anytime by the aid of the rotational round hole in the center of the base plate, so that the proceeding direction of a saw blade is changed easily, a saw web can cut smaller arcs, and a processing range of the scroll saw is widened; in addition, since the upwards-swelling clamping arc strips are arranged, the universal base is rapid to connect, firm in fixation and high in practicality.

Description

Universal base of scroll saw

Technical Field

The invention relates to a woodworking processing device, in particular to a universal base of a curve saw.

Background

The jig saw is a common woodworking tool, and can cut complex curved shapes by utilizing a saw blade which moves up and down quickly to cut curves. The base and the machine body of the existing jig saw are fixedly connected, and the machine body cannot rotate, so that the rotating radius of the whole jig saw is limited to a certain extent.

Disclosure of Invention

The invention mainly solves the technical problems in the prior art, and provides a universal base of a curve saw.

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

the utility model provides a universal base of scroll saw, universal base of scroll saw contain a rectangular substrate, the center of substrate be equipped with one and rotate the round hole, the head of substrate be equipped with a pair of block protrudingly, the afterbody of substrate is equipped with a pair of block arc strip and the block bead of a decurrent uplift.

As a preferred embodiment of the invention, a limit protrusion protruding upwards is arranged between the clamping arc strips.

The universal base of the scroll saw utilizes the rotating round hole at the center of the substrate, and a user can adjust the angle of the whole machine body at any time, so that the advancing direction of the saw blade is easily changed, the saw blade can cut smaller circular arcs, and the processing range of the scroll saw is improved. In addition, due to the fact that the clamping arc strips protruding upwards are arranged, connection is fast, fixing is firm, and practicability is high.

Detailed Description

The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the scope of the present invention will be more clearly and clearly defined.

As shown in fig. 1 to 2, a universal base 1 of a jigsaw of the present invention includes a rectangular substrate 2, a rotation circular hole 3 is formed at the center of the substrate 2, a pair of engaging protrusions 4 are formed at the head of the substrate 2, and a pair of upwardly protruded engaging curved bars 6 and a downwardly bent engaging protrusion 7 are formed at the tail of the substrate 2.

A limit protrusion 5 protruding upwards is arranged between the clamping arc strips 6.

The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through the inventive work should be included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope defined by the claims.
