Description

Saw blade fixing mechanism

The present invention relates to a saw blade locking mechanism consisting of two holding devices, U-shaped bends and a handle located at two ends constituting the saw blade.

Generally, the fasteners are used for sawing different materials and for fastening saw blades having a wire shape or having a small width and flatness. Generally the saw blade or wire is fixed to the ends between the rigid jaws at both ends of the bend. The jaws have rigid fastening parts, mainly at both ends of the bend, with other moving parts consisting of plates, through which the screws are screwed onto the fastening parts. When the screw is rotated in one direction, the moving part is fixed to a flat surface, and as a result, the saw blade is fixed.

According to the method used for decades, the fixed state is uncertain, the positioning is incorrect, and often the problem is that the saw blade is twisted and the saw deforms while sawing while the plate is tightened.

It is an object of the present invention to provide saw holders, in particular saw blade holders, which are used by jewelers regardless of their relatively small and flat structure or wire shape.

According to the saw blade fixing mechanism of the present invention, two fixing devices are identical, and each of the fixing devices is composed of a fixing body having a longitudinal passage member, and the cross-sectional size of the passage member matches the cross-sectional size of the saw blade. It is possible to control and center the saw blade, the first screw of the fixing function assembled in the vertical direction with respect to the passage member is configured in the fixing body, it is possible to tighten the corresponding end of the saw blade in the passage member It features.

According to the present invention, there is also provided a saw blade fixing mechanism capable of easily replacing defective or worn components. Thus all components consisting of bends, fixtures and handles can be replaced.

In order to lighten the saw blade holding mechanism, the curved portion is constituted by a compression pipe having sufficient strength or similar properties for the work performed by the jewelers.

In addition, the handle is covered with foamed plastic, so that when the user sweats, the saw blade fixing mechanism can be prevented from slipping.

The present invention is described in more detail with reference to the accompanying drawings.

A U-shaped bend 1 with two fasteners 3, 4 for the saw blade 5 and a handle 2 is shown in FIG. 1. The five components can be replaced and separated. For example, screws or similar devices are used to join the different components together.

The simplest variant of the fixing device 3, 4 is shown in FIG. 2. The fixing body 31 to which the longitudinal passage member 32 is fitted is constituted by the fixing devices 3 and 4, and the cross-sectional dimension of the passage member 32 coincides with the cross-sectional dimension of the saw blade 5, The saw blade 5 is controlled and centered. Once the saw blade 5 is fitted into the passage member 32, the saw blade 5 is tightened against the wall of the passage member 32 by a screw 33 having a toothed screw head 34. The saw blade is fixed. The fixing devices 3 and 4 are identical.

Referring to another variant of FIG. 3, a passage member 36 is constructed across the stationary body 35, and a screw 37 with a toothed screw head 38 is fitted to the stationary body 35. Is tailored. Compared to the stationary body 31, another screw 39 is fitted to the stationary body 35, which screw 39 is located in the extension of the screw 37. The screw 39 secures the saw blade 5 between the screw 37 and the ends of the screws 39 by means of the screw 39, tightens the fixation state, tightens it precisely, and at the same time advantageous light for the saw blade fixing mechanism. The fixed body 35 can be manufactured by an alloy). Also with the screw 39, the screws 37, 39 can be adjusted to make the saw suitable for left- or right-handed users.

Referring to the fixing device of FIG. 4, the fixing body 35 is the same as or similar to the fixing body of FIG. 3, and the fixing body 35 has a screw 37 which is moved by the screw head 38 of the tooth structure. Is fitted on. The member 41 has a T-shape, and the fixing body 35 is formed on the side of the leg portion formed in the member 41 by a screw 39 'longer than the screw 39. Are assembled. The fixing body 35 is fixed to the member 41 by the screw 39 ', and as shown in FIG. 4, a saw blade (B) between two ends of the screw 37 and the screw 39' is fixed. 5) is fixed. In this case, the member 41 is assembled so that the leg portion of the member 41 is located in the plane formed by the curved portion 1, so that the saw blade 5 is eccentric with respect to the plane of the curved portion 1. It is advantageous because the working plane is completely visible when the work is carried out on a small workpiece.

On the other hand, according to the above configuration, the fixing body 35 can be assembled to the left side or the right side of the member 41, so that the saw can be adapted for the left-handed or right-handed user. Further, for example, by using the screw 42 shown only in FIG. 4, the member 41 is fixed on the curved portion 1 together with the fixing body 35 of FIG. 3 and the fixing body 31 of FIG. 2. Also, by the eccentric position, a saw having a length larger than the distance from one end of the curved portion 1 can be used.

The handle 2 is assembled to the saw blade fixing mechanism, the handle can be replaced and assembled by screws or similar devices, and is made of a cylindrical part covered with foamed plastic, so that the saw blade fixing mechanism can move accurately.

The above components provide variations and further variations may be provided.

According to the advantage of the saw blade fixing mechanism of the present invention, the saw blade is controlled and centered in the passage member of the fixed body, the dimension of the passage member matches the dimension of the saw blade, while the saw blade is substantially It does not form a space that can move in the passage member.

According to a variant, the saw blade is tightened between the screw located on the side of the passage member and the ends of the screw for tightening or loosening the saw blade. As a result, the saw can be modified for left and right handed users. In fact, when the saw blade is assembled, it is essential that the saw blade is tightly fixed between the two ends of the bend, and for this purpose, by means of the hands or abdomen, the bend is pulled against the obstacle, and then the screw is Is released. Depending on the left- or right-handed user, the screw to be tightened and loosened must be positioned on the correct side, in which case it is sufficient to replace the screw with a toothed screw head in place of the fixed screw. During assembly, the modifications can be very easily provided by future users, as long as they provide a saw blade locking mechanism for left- or right-handed users, without providing other special configurations.

According to another embodiment of the present invention, the fixing device has a T-shaped member and a T-shaped member so that the saw blade is slightly moved to the outside of the plane formed by the curved portion so that the working member can be seen. The head of the member is perpendicular to the plane of the bend, and the fixing body is assembled to the left or right side of the leg of the member according to the user's hand. The member is fixed by a screw that is formed across the leg portion formed in the T-shaped member, and the configuration of the screw ends in the passage member. The saw blade is fixed by screws and toothed screw heads. When commencing work, assembling the stationary body on one side or on the other side provides a saw for left- or right-handed users. In addition, according to the above modification, a saw having a saw blade having a length greater than the gap between the ends of the curved portion can be used.
