As shown in Figure 1, the utility model is a kind of hand saw with trimming function, comprises knife handle 1, and knife handle 1 is connected double-sided blade 2, and the trimming mechanism is detachably installed on double-sided blade 2.

In this embodiment, the knife handle 1 is a curved handle, and one end of the knife handle 1 is detachably connected to the double-sided blade 2 through bolts. The advantage of using the curved handle 1 is that the operator can perform force operation better. At the same time, the disadvantage of the curved handle 1 is that when one edge of the curved handle is worn, it is necessary to disassemble the curved handle 1 and turn it over 180° before connecting the two blades. Face blade 2.

In other embodiments, the knife handle 1 can be a straight handle. The advantage of adopting the straight knife handle 1 is that there is no need to replace the connecting position with the double-sided blade 2, but the disadvantage is that the operation is not very smooth.

As shown in FIG. 2 , the sawtooth 2 - 1 on both sides of the double-sided blade 2 adopts different numbers of teeth to meet different cutting needs. The double-sided blade 2 is made of carbon tool steel, which requires heat treatment to a hardness of about HRC60.

In this embodiment, the thickness of the double-sided blade 2 is 6.7 mm, which is beneficial to reduce the resistance during cutting. The tooth density on both sides is 14 teeth per inch and 17 teeth per inch to deal with different tree species. The double-sided blade 2 is made of steel SK5, and the hardness after quenching is HRC60-63.

The sharpening mechanism includes a grinding frame 3 and a grinding slider 4. The grinding frame 3 is located at the periphery of the sawtooth on one side, and the grinding frame 3 is slidably provided with a grinding slider 4 .

Specifically, as shown in Figures 3-4, there is a sawtooth groove 3-1 in the middle of the grinding frame 3, which is used to accommodate the sawtooth 2-1, and both sides of the sawtooth groove 3-1 are provided with chute 3-2, and the chute In 3-2, slide and install the grinding slide block 4. The grinding frame 3 is connected to the double-sided blade 2 by bolts.

As shown in Figure 5, the middle part of the grinding slider 4 is provided with a groove 4-1 up and down, which is used to be embedded in the chute 3-2. Cover abrasive 5.

In order to facilitate manufacturing and assembly, the grinding frame 3 and the grinding slider 4 adopt a split structure.

In order to fix the grinding frame 3 and the grinding slider 4, the support bolt 6 is threaded on the grinding frame 3, and the tail of the support bolt 6 faces the chute 3-2, when it is necessary to fix the grinding frame 3 and the grinding slider 4 , slide the grinding slider 4 to the bottom of the support bolt 6, and rotate the support bolt 6 until the bottom of the support bolt 6 is against the grinding slider 4.

The working process of the present utility model is as follows:

When one side of the sawtooth 2-1 is worn, the grinding frame 3 is installed on the outer periphery of the worn side of the sawtooth 2-1, and the grinding slider 4 is moved for grinding.
