Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to a disassembly knife.

The purpose of the present invention is to ensure the support of the blade, to easily replace the blade, to easily assemble and disassemble the blade, and to make it easy to clean the dissecting knife after use.

(Prior art) Conventionally, dissecting knives could not be disassembled, so when cleaning the dissecting knife after use, dirt such as pieces of meat and blood stains tend to adhere to the gap between the joint between the blade and the grip body, making it difficult to clean. It was difficult and unhygienic.

Regarding the replacement of the blade, although there were some dissecting knives that were replaceable, many had a single-point fulcrum or were simply fitted together, so they remained in use for many years. The blade would rattle or come off during use, making it very dangerous.

(Problems to be Solved by the Invention) Conventional dissecting knives were as described above, making them difficult to clean after use, and the fixing mechanism of the blade had some problems.

(Means for Solving the Problems) In view of these drawbacks, the present invention provides a support column on the handle handle having a gripping part, and a blade fitting groove that extends from the tip of the handle handle toward the middle part. A magnet is installed inside the blade fitting groove, a fitting support piece is provided at the tip of the handle handle, and a side arm shaped to fit into the handle handle is provided with a support post of the handle handle. Drill a corresponding support hole, insert this support hole into the support column, fit the blade into the fitting groove, attach it to the magnet, and support the side arm on the fitting support piece of the handle handle. By removably fixing the handle handle, blade body, and side arm, the blade body is supported securely, the blade body can be easily replaced, and the blade body can be easily assembled and disassembled. This makes cleaning easier.

(effect of invention) The operation of the present invention will be explained.

When replacing the blade of the disassembly dissecting knife according to the present invention, first remove the side arm from the fitting support piece of the handle handle that has the gripping part, rotate it approximately 90 degrees, or rotate it as appropriate and leave it as it is. Remove the side arm from the handle handle that has the gripping part, and remove the blade from the blade fitting groove of the handle handle. At this time, since the blade is fixed by a magnet, the blade can be easily removed from the blade fitting groove by simply pulling the blade upward. Next, the blade to be replaced is fitted into the blade fitting groove of the handle having the gripping portion, and is magnetically attached to the magnet. and,
Rotate the side arm and securely fix both sides using the fitting support piece on the handle handle.

Further, during cleaning, the side arm is removed from the fitting support piece of the handle handle having the gripping portion in the same manner as described above, and the two are removed by appropriately rotating the side arm and cleaning is performed.

(Example) An embodiment of the present invention will be described based on the drawings.

As shown in FIGS. 1 to 3, the disassembly knife 1 according to the present invention has a support column 4 on a handle handle 3 having a grip portion 2. As shown in FIGS. Further, the surface where the gripping portion 2 contacts the side arm 8 is approximately arc-shaped,
The side arm 8 is designed to be able to rotate only about 90 degrees. A blade fitting groove 5 is bored from the tip of the handle handle 3 toward the middle part, and a magnet 6 is installed inside the blade fitting groove 5. Further, a fitting support piece 7 having an L-shaped cross section is provided at the tip of the handle handle 3.

On the other hand, a support hole 9 corresponding to the support column 4 of the handle handle 3 is bored in the side arm 8 in a shape to fit into the handle handle 3. Further, a locking protrusion 11 for fixing the blade body 10 is provided on the back side of the side arm 8. inserting the support hole 9 into the support column 4 of the handle handle 3; inserting the support hole 9 into the support column 4 of the handle handle 3; inserting the support hole 9 into the support column 4 of the handle handle 3;
A blade 10 having a fixing hole 12 in the blade fitting groove 5
At the same time, the side arm 8 is supported by the fitting support piece 7 of the handle handle 3, and the locking protrusion 11 of the side arm 8 is fitted into the fixing hole 12 of the blade body 10. The handle handle 3, the blade body 10, and the main body 8 are detachably fixed to each other.

Blade body 10 of the disassembly knife 1 according to the present invention
When replacing the blade body 1, first remove the side arm 8 from the fitting support piece 7 of the handle handle 3 having the grip part 2, and
Rotate the side arm 8 approximately 90 degrees so that the locking protrusion 11 of the side arm 8 is released from the fixing hole 12 of 0, or remove the side arm 8 from the handle handle 3, and pull the blade 10 up from the magnet 6. Remove it from the blade fitting groove 5 of the handle handle 3. At this time, the side arm 8 does not rotate more than approximately 90 degrees due to the substantially arcuate shape of the grip portion 2. Next, the blade 10 to be replaced is fitted into the blade fitting groove 5 of the handle handle 3 having the grip portion 2, and is magnetically attached to the magnet 6. Then, when the side arm 8 is rotated to its original position, the locking protrusion 11 of the side arm 8 is inserted into the fixing hole 12 of the blade body 10.
The fitting support piece 7 of the handle handle 3 can securely fix the two.

In addition, when cleaning the disassembly dissecting knife 1 of the present invention, the side arm 8 is removed from the fitting support piece 7 of the handle handle 3 having the grip part 2 in the same manner as described above, and the handle is rotated approximately 90 degrees. The side arm 8 is removed from the handle 3, the blade body 10 is pulled up from the magnet 6, and the handle handle 3, side arm 8, and blade body 10 are disassembled and cleaned. Therefore, unlike cleaning a conventional dissecting knife, every corner can be cleaned.

Further, in the embodiment shown in FIG. 4, the grip portion 2 of the handle handle 3 is wave-shaped to make it easier to hold, and the operation and effect are the same as those of the previous embodiment.

In this embodiment, a support piece is provided on the peripheral edge of the tip of the support column 4, a corresponding support hole is provided on the outer peripheral edge of the support hole 9 of the side arm 8, and the support piece is provided on the upper peripheral edge of this support hole. Provided with a rotation hole that can be rotated,
The handle handle 3, side arm 8, and blade body 10 may be prevented from coming off.

(Effects of the invention) According to the disassembly knife according to the invention, the handle handle is provided with a support column and a fitting support piece, a blade fitting groove is provided, and the side arm is shaped to fit therein. A support hole is provided, the support column is inserted into the support hole, the two are rotated, and the two are fitted and fixed, and a magnet is installed in the blade fitting groove as a mechanism for fixing the blade to the handle handle. By installing the blade inside and magnetically attaching the blade to this magnet, the support of the blade is ensured, the blade can be easily replaced, and it can be easily assembled and disassembled. Therefore, it is hygienic as it becomes easier to clean the dissecting knife after use.
Very convenient.
