Description

Blade body with groove

The present invention relates to a woodworking tool, in particular to a knife body with a groove.

In order to be used in different situations, woodworking knives derive different forms. Among them, there is a composite tool, which is a tool composed of two different metal materials. The steel of the general blade will be different from the steel of the handle and the body. The blade made of steel with higher hardness is installed in the integrally formed blade body. However, it is known that the combination of the two steels is not stable, and the blade is easy to fall off and damage. It can strengthen the process technology of firmly combining the blade with the blade.

The invention provides a blade body with a groove, the main purpose of which is to enable the blade edge to be firmly combined with the blade body.

In order to achieve the aforementioned purpose, the novel blade body with a groove includes

A shank;

A blade body portion is connected to one end of the shank portion, which defines that the shank portion and the blade body portion are connected and extended along a longitudinal direction, the blade body portion has a plurality of clamping grooves extending along the longitudinal direction, the clamping The groove is provided with a blade.

As can be seen from the foregoing, the novel blade body with a groove is mainly provided with a plurality of clamping grooves extending along the longitudinal direction of the blade body portion, so that the blade is installed in the clamping groove, and then the blade can be stabilized The purpose of combining with the blade body.

The present invention provides a blade body with a groove. In the first embodiment, please refer to FIG. 1 and FIG. 2, including:

A shank portion 10, which is cylindrical;

A blade body portion 20 is connected to one end of the shank portion 10 to define that the shank portion 10 and the blade body portion 20 are connected and extended along a longitudinal direction X. The blade body portion 20 has a plurality of cards extending along the longitudinal direction X The fixing groove 21 is used for accommodating a blade 90.

In a preferred embodiment, the number of the clamping grooves 21 is two, and the two clamping grooves 21 are disposed at symmetrical positions of the blade portion 20.

In a preferred embodiment, the blade body portion 20 has a first fixing surface 211, a second fixing surface 212, and a third fixing surface 213 facing the locking groove 21, when the blade 90 is installed on the When the groove 21 is locked, the first fixing surface 211, the second fixing surface 212, and the third fixing surface 213 are all attached to the blade 90, so that the blade 90 is firmly installed in the clamping groove 21 to further improve the stability between the blade 90 and the blade body 20; the number of the first fixing surface 211, the second fixing surface 212 and the third fixing surface 213 is the same as the number of the clamping groove 21 Therefore, when the number of the locking grooves 21 is two, the blade body portion 20 has two first fixing surfaces 211, two second fixing surfaces 212, and two third fixing surfaces 213, each A first fixing surface 211, a second fixing surface 212, and a third fixing surface 213 all face one of the fixing grooves 21.

In a preferred embodiment, the locking groove 21 is a rectangular groove, and an end 91 of the blade 90 installed on the locking groove 21 is also rectangular.

In a preferred embodiment, the blade body portion 20 has a stop structure 22, the stop structure 22 is located on one side of the clamping groove 21, and the stop structure 22 is attached to the blade 90 to provide The blade 90 is supported, and the third fixing surface 213 is located in the blocking structure 22.

Specifically, it is defined that the first fixing surface 211 and the third fixing surface 213 are parallel to each other and separated by a distance, and the second fixing surface 212 is perpendicular to the first fixing surface 211 and the third fixing surface 213, And located between the first fixing surface 211 and the third fixing surface 213, the second fixing surface 212 is connected to one end of the first fixing surface 211 and the third fixing surface 213, so that the second The fixing surface 212 is the bottom surface of the fixing groove 21, and defines that the extending direction of the first fixing surface 211 and the third fixing surface 213 is a depth direction H, and the length of the third fixing surface 213 in the depth direction H is greater than the length The length of the first fixing surface 211 in the depth direction H.

Preferably, the length of the first fixing surface 211 in the depth direction H is defined to be between 0.3 and 0.5 mm, and the depth of the locking groove 21 in the depth direction H is 0.3 to 0.5 mm.

As can be seen from the foregoing, the present invention is mainly to provide the blade body 20 with a plurality of clamping grooves 21 extending along the longitudinal direction X, so that the blade 90 can be installed in the clamping groove 21, and then welding Means, so that the blade 90 can be more firmly coupled to the blade portion 20.
