The technical scheme that the utility model solves its technical problem adopts is:

A saw capable of replacing multiple saw blades, characterized in that it includes: a handle, which has a gripping portion on one side, and a hand guard on the other side, and the hand guard is inwardly facing the end A slot is recessed; several sawing parts that can be replaced and installed on the handle, each sawing part is placed in the slot of the hand guard at one end, and a detachable hand guard is attached to the handle The sawing part is fixed by a fixed device of the type.

In the aforementioned saw that can replace multiple saw blades, the several sawing parts include a bow for installing the saw blade and a saw blade, the bow and the saw blade respectively have an insertion part at one end, and the bow The inserting portion of the end and its inserting portion and the saw blade have a shape corresponding to the slot of the handle and can be inserted correspondingly. The handle has two first through holes, and the bow portion and the saw blade are in the One end of the insertion part has two second perforations respectively, and the handle communicates with the perforations of the bow part and the saw blade when any two are engaged. together and fixed.

In the aforementioned saw that can replace multiple saw blades, the several sawing parts include a bow for installing saw blades and a saw blade, and the bow and the saw blade have slots for the handle at one end respectively The opposite shape and corresponding insertion, the fixing device is provided with a clamping part on the side of the handle for clamping and fixing the bow or the saw blade after being inserted into the slot.

The beneficial effect of the utility model is that in addition to saving purchase cost without buying various types of saws, it also saves storage space and is easy to carry, so that the gripping part and the sawing part can be easily disassembled and assembled.

Detailed ways

Please refer to Fig. 1 to Fig. 3, shown in the figure is the selected embodiment structure of the utility model.

This embodiment provides a saw that can replace various saw blades, which includes:

A handle 1, which has a grip portion 11 on one side, and a hand guard 12 on the other side, and the hand guard 12 is provided with a slot 13 inwardly recessed on the end surface 121;

A plurality of sawing parts 2 that can be replaced and installed on the handle 1, each sawing part 2 is placed in the slot 13 of the hand guard 12 at one end, and the hand guard 12 of the handle 1 is provided with a A detachable fixing device 3 fixes the sawing part 2 .

In this embodiment, several sawing parts 2 include a bow 21 which can be equipped with a saw blade, a saw blade 22 and another saw blade 23. The bow 21 and the saw blade 22 respectively have an insert at one end. There are parts 211, 221, 231, the end of the bow part 21 and its insertion part 211 and the insertion part 221 of the saw blade 22 respectively have a shape opposite to the slot 13 of the handle 1 and can be inserted correspondingly. The handle 1 has two first through holes 14, and the bow portion 21 and the saw blade 22 have two second through holes 212, 22 at one end of the insertion portion 211, 221, 231 respectively.

2, 232, the handle 1 communicates with the through holes 212, 222, 232 of the bow 21 and the saw blade 22 when any two are engaged, and the fixing device 3 passes through each of the two with a locking member 31 respectively. Perforate the holes 212 (222, 232) and lock and fix them.

Therefore, when the worker is sawing, he can choose a suitable saw blade. For example, when sawing a workpiece with a thinner thickness, he can choose the saw blade 21 locked by the bow 21 to perform the sawing action. When sawing thicker workpieces, the lock 31 on the handle 1 can be loosened, and the saw blade 22 can be fixed with the lock 31 after replacing the saw blade 22 to perform sawing.

It can be seen that the main advantage of the present utility model is that when it is desired to perform sawing work in different forms, it is only necessary to easily replace the sawing part 2 matched with the handle 1 to perform the sawing work, which not only saves the purchase of different forms The cost of the saw can also save the storage space of various saws.

Of course, there are still many examples of the present invention, between which only the details vary. Please refer to Fig. 4, which is the second embodiment of the present utility model, wherein the plurality of sawing parts 2A include a bow portion and a saw blade (not shown in the figure) on which a saw blade can be installed, the bow portion and the saw blade The saw blades have a shape opposite to the slot 13 of the handle 1 at one end and can be inserted correspondingly. The fixing device 3 is provided with a slot 13 on the side of the handle 1 for the bow or the saw blade to be inserted into. The fixed clamping part 32 is clamped behind.

In this embodiment, the difference from the first embodiment is that the bow and the saw blade are not provided with the insertion parts 211, 221, 231 as in the first embodiment, and the guard is inserted into the bow and the saw blade. The slot 13 of the hand 12 is fixed by the clamping part 32, and the sawing part 2A can be easily replaced through the switch of the clamping part 32, so as to achieve the same effect as the first embodiment.

Please refer to FIG. 5 , which is a third embodiment of the present invention, wherein the fixing device 3 can also be a button-type pressing component 33 to fix the saw blade.
