It should be noted that, without conflict, the embodiments of the present utility model and features of the embodiments may be combined with each other. The utility model will be described in detail below with reference to the drawings in connection with embodiments.

In order that those skilled in the art will better understand the present utility model, a technical solution in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present utility model without making any inventive effort, shall fall within the scope of the present utility model.

It should be noted that the terms "first," "second," and the like in the description and the claims of the present utility model and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate in order to describe the embodiments of the utility model herein. Furthermore, the terms "include" and "have," and the like, mean that other content not already listed may be "included" and "provided" in addition to those already listed in "include" and "provided; for example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements not expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

As shown in fig. 1, the utility model relates to a hand saw with a blade trimming function, which comprises a tool holder 1, wherein the tool holder 1 is connected with a double-sided blade 2, and a blade trimming mechanism is detachably arranged on the double-sided blade 2.

In the embodiment, the tool holder 1 is a bent handle, and one end of the tool holder 1 is detachably connected with the double-sided blade 2 through a bolt. The bent handle 1 has the advantages that an operator can perform force operation better, and meanwhile, the bent handle 1 has the disadvantage that after one side of the cutting edge is worn, the bent handle 1 needs to be disassembled and turned over for 180 degrees to be connected with the double-sided blade 2.

In other embodiments, the handle 1 may be a straight handle. The advantage of using a straight handle grip 1 is that the connection location with the double-sided blade 2 does not need to be changed, and the disadvantage is that the operation is not very handy.

As shown in fig. 2, the saw teeth 2-1 on both sides of the double-sided blade 2 have different numbers of teeth to cope with different cutting needs. The double-sided blade 2 is made of carbon tool steel and needs to be heat treated to a hardness of about HRC 60.

In this embodiment, the thickness of the double-sided blade 2 is 6.7mm, which is advantageous in reducing resistance at the time of cutting. The tooth density on both sides is 14 teeth and 17 teeth per inch, respectively, to cope with different tree species. The double-sided blade 2 adopts the steel as SK5, and the hardness after quenching is HRC60-63.

The sharpening mechanism comprises a sharpening frame 3 and a sharpening slider 4. The coping frame 3 is arranged on the periphery of the unilateral saw teeth, and a coping slide block 4 is arranged on the coping frame 3 in a sliding manner.

Specifically, as shown in fig. 3-4, a sawtooth groove 3-1 is formed in the middle of the grinding frame 3 and used for accommodating the sawtooth 2-1, sliding grooves 3-2 are formed in two sides of the sawtooth groove 3-1, and a grinding sliding block 4 is slidably arranged in the sliding grooves 3-2. The coping frame 3 is connected with the double-sided blade 2 through bolts.

As shown in fig. 5, grooves 4-1 are provided up and down in the middle of the coping slider 4 for being embedded in the chute 3-2, the inner side surface of the coping slider 4 is adapted to the side surface of the saw tooth 2-1, and the abrasive 5 is coated.

In order to facilitate production, manufacture and assembly, the coping frame 3 and the coping slide 4 adopt a split structure.

In order to fix the grinding frame 3 and the grinding slide block 4, the grinding frame 3 is connected with the supporting bolt 6 in a threaded manner, the tail of the supporting bolt 6 faces the sliding groove 3-2, when the grinding frame 3 and the grinding slide block 4 are required to be fixed, the grinding slide block 4 is slipped below the supporting bolt 6, and the supporting bolt 6 is rotated until the bottom of the supporting bolt 6 abuts against the grinding slide block 4.

The working process of the utility model is as follows:

after the saw teeth 2-1 on one side are worn, the grinding frame 3 is arranged on the periphery of the saw teeth 2-1 on the worn side, and the grinding slide block 4 is moved for grinding.

It is to be understood that the above embodiments are merely illustrative of the application of the principles of the present utility model, but not in limitation thereof. Various modifications and improvements may be made by those skilled in the art without departing from the spirit and substance of the utility model, and are also considered to be within the scope of the utility model.
