Edge trimmer

This creation is related to woodworking tools, especially with regard to an edge trimmer.

In the woodworking work such as wood furniture or decoration, the edge of the item is often not flat due to skin or splicing, which makes it safe to use and not ideal in appearance. Therefore, in order to facilitate the edge of the item For trimming and flattening, it is necessary to cut off the protruding edge portion by the cutter to make it flat and safe, and in order to facilitate the cutting operation, the conventional technique discloses a dressing tool as shown in the first figure, which is used for In order to achieve the main technical content of trimming the edge of the article, the blade portion (2) of the blade (1) protrudes from the side of a sliding surface (3), and the sliding surface (3) is slidably attached thereto. At the same time as the edge portion of the article is slipped, the protruding portion of the edge is cut off by the blade portion (2), thereby achieving the effect and purpose of trimming the edge of the article.

However, due to the wide variety of wooden objects, the shape is also very varied, and the edges of the objects are not all at right angles. Therefore, the conventional technology can achieve the effect of trimming the edges of the objects, but only for fixed right angles. The edge, still limited in its use, is still not an ideal technical content.

Therefore, the main purpose of the present invention is to provide an edge trimmer which, in addition to trimming the right-angled edges, can be adapted by the user to be applied to the trimming of different angular edges, compared to conventional techniques. More flexible and convenient to use.

Therefore, in order to achieve the above object, the edge trimmer provided by the present invention is provided with a blade with a knife seat, and the tool holder is movably accommodated in a base, and the tool holder can be The activity is to change the angle of the angle between the blade and the one of the contact faces of the base, and the edge trimming effect can be provided according to the angle change of the edge of different articles.

In addition to the technical content, the edge trimmer further includes a guide portion and a locking portion in addition to the base, the seat and the blade. The pedestal has a pedestal body and is disposed in the pedestal body for accommodating one of the locomotives, and an opening is disposed on the pedestal and communicates with the accommodating space, and The contact surface is located on one side of the opening. The blade has a blade body fixed to the blade holder, and at least one blade portion is located outside the opening and spaced apart from the contact surface by the trimming angle. The guiding portion is disposed between the seat and the base, and guides the seat to move between the first position and the second position in the receiving space. When the seat is located in the first position, the trimming The value of the angle is different from the value when the seat is in the second position. The engaging portion can restrain and position the seat in the receiving space, so that the value of the trimming angle is maintained.

The guiding portion has a guiding space and a conductor extending and sliding in the guiding space, and the guiding space and the conductor are disposed on the base and the holder.

The guiding space is an arc-shaped hole, and is disposed on the base, and the conductor is in the shape of a rod, is disposed on the seat, and is slidably engaged in the guiding space by the rod end.

Wherein, the locking portion has a locking member which is located outside the other outer end surface of the base body and is coupled to one end of the shaft of the conductor, and is clamped by reducing the distance between the locking member and the holder The base body positions the seat.

The coupling structure between the fastener and one end of the shaft of the conductor is screwed.

The holder has a seat body and is received in the receiving space, and a joint portion is disposed on one side of the blade body and fixed to the blade body.

Wherein, the joint further comprises a groove recessed on one side of the seat body and the slot is communicated with the opening.

Wherein, the opening extends linearly, and the contact surface is located on one side of the extending direction.

Wherein, the opening and the contact surface are on the same plane.

First, referring to the second to fifth figures, the edge trimmer (10) provided in the first preferred embodiment of the present invention mainly comprises a base (20) and a knife seat ( 30), a guide (40), a blade (50) and a card portion (60).

The base (20) has a base body (21) which is hollowed at both ends and has a shell shape, and a top open receiving space (22) is located in the shell of the base body (21). The opening (23) extending in a straight line is formed on the bottom end of the base body (21) and communicates with the receiving space (22), and a contact surface (24) on the same plane as the opening (23) , located at the bottom end of the base body (21) and corresponding to one side of the direction in which the opening (23) extends.

The knife seat (30) is movably located in the accommodating space (22), and has a substantially rectangular plate-shaped blade body (31), wherein the two ends of the long axis are adjacent to the pedestal body (21) ) on the inner side of the left and right side wall (211) (212), and the direction of the body is the same as the direction of extension of the opening (23), so that the short end of the blade body (31) is one end (311) In the opening (23), a through hole (32) extends along the long axis direction of the blade body (31) and is disposed on the short end (312) of the blade body (31). The groove-shaped joint portion (33) is recessed on one end (311) of the short shaft of the blade body (31) for inserting and coupling the blade (50).

The guiding portion (40) has a guiding space (41) and a conductor (42) extending through the guiding space (41), and the conductor can be restrained by the guiding space (41) ( 42) a moving path, specifically, the guiding space (41) is an arc-shaped hole (411) having two arcs of the same arc, and is disposed on the left and right sides of the base body (21) (211) (212), and the axis between the centers of curvature of the arcuate holes (411) is parallel to the extending direction of the opening (23);

The conductor (42) is in the form of a rod extending through the through hole (32) and coupled to the blade body (31), and the two ends are respectively extended and slidably connected to the arc holes ( 411), so that the seat (30) can be guided by the guide (40) on a predetermined moving path, as shown in the sixth and seventh figures ( 22) moving between a first position and a second position.
