As shown in FIG. 1 , in this embodiment, the chainsaw 10 includes a housing 100 , a power device 110 , a cutting member 120 , a handle 130 , and a grip portion 140 . Wherein, the power device 110 is arranged in the casing 100 to provide power for the rotation of the cutting member 120 . For example, power unit 110 may be a motor. It should be noted that the power device 110 can be powered by an external power source, such as connecting the power device 110 to the external power source through a connection line, or a DC power source can be provided in the casing 100 to provide power for the power device 110 . In this embodiment, a power source is used to provide power for the power device 110 , the power source is detachably disposed in the casing 100 , the power source is a battery pack, and the power device 110 is a DC motor. The battery pack is adopted, so that the working area of the chain saw is not restricted by the power cord, and the movement is more flexible. When the chainsaw is not in use, the battery pack can be removed to reduce the weight of the chainsaw.

The cutting member 120 is connected with the power device 110 and driven by the power device 110 . In this embodiment, the cutting member 120 is a strip saw chain with cutting teeth, and the saw chain can rotate under the drive of the power device 110 to complete the cutting work.

One end of the handle 130 is rotatably connected to the housing 100 , and the other end is provided with a gripping portion 140 . Wherein, the handle 130 is provided with an accommodating chamber, and when the handle 130 is rotated to a position overlapping with the cutting member 120, the cutting member 120 is accommodated in the accommodating chamber. Wherein, the position where the handle 130 overlaps with the cutting part 120 means that the cutting part 120 is facing the accommodating cavity of the handle 130, and the cutting part 120 is located above the handle 130, which is the position shown in FIG. 3. At this time, the cutting part 120 is accommodated in the handle 130. In addition, as shown in FIG. 2, when the chain saw is in the extended position, the handle 130 is rotated to a position separated from the cutting member 120, and the cutting member 120 is exposed for cutting work. At this time, the cutting member 120 is substantially on the same straight line as the handle 130 , and the cutting member 120 is exposed to the outside for cutting work.

The length of the handle 130 is greater than or equal to the length of the cutting member 120 . When the handle 130 is rotated to a position overlapping with the cutting part 120 , the cutting part 120 is completely accommodated in the accommodating chamber of the handle 130 , which avoids the phenomenon that the cutting part 120 is not completely accommodated in the handle 130 .

As shown in Figure 1, in this embodiment, the chainsaw 10 is also provided with a support portion 160, the support portion 160 is connected to the housing 100, and when the handle 130 is rotated to the unfolded position, the support portion 160 is located between the grip portion 140 and the cutting member. Between 120. In the working state, the operator can hold the grip part 140 with one hand and the support part 160 with the other hand, so that the two arms form a triangle with the handle 130, making the operation of the chain saw more stable and safe.

As shown in FIG. 3 , when the chain saw is in a non-working state, the handle 130 is rotated to a position coincident with the cutting member 120 , and at this time, the cutting member 120 is accommodated in the accommodating cavity of the handle 130 . The occupied space of the cutting part 120 is saved, and the transportation is also very convenient, and the cutting part 120 will not cause harm to the human body.

As shown in FIG. 2 , the chain saw is further provided with a shield 150 , one end of which is connected to the housing 100 and arranged on the cutting member 120 . When the cutting part 120 is cutting wood or other objects, the saw chain rotating at a high speed may pick up wood chips or other debris, and the guard 150 can prevent the wood chips or other debris from floating upwards and prevent the wood chips or other debris from entering the operator's eyes . In this embodiment, one end of the shield 150 is rotatably connected to the casing 100 , and the other end has an end extending downward. The shield 150 can be hingedly connected with the casing 100 , that is, the shield 150 can be arranged on the cutting part 120 , and can also be opened to expose the cutting part 120 . The end portion of the shield 150 extending downward can protect the end portion of the cutting member 120 , preventing the operator from injuring the operator when the operator rotates the handle 130 to a position overlapping with the cutting member 120 .

As shown in FIG. 2 , in this embodiment, the chainsaw is further provided with a control key 170 , which is disposed on the grip portion 140 and connected to the power device 110 . The control key 170 controls the start and stop of the power device 110 , and further controls the operation and stop of the cutting member 120 . The control key 170 is arranged on the grip part 140, which can facilitate the manipulation of the operator. In other embodiments, the control key 170 may not be provided, and the power device 110 may be directly connected to the power source.

As shown in FIG. 2 , in this embodiment, a ventilation hole 132 is opened on the handle 130 . When the cutting part 120 cuts a relatively wet object, after the cutting is finished, a certain amount of moisture will remain on the cutting part 120, and a ventilation hole 132 is provided on the handle 130, so that when the cutting part 120 is accommodated in the accommodating chamber of the handle 130, The accommodating cavity can be kept well ventilated, and then the moisture remaining on the cutting member 120 can be taken away, so as to prolong the service life of the chain saw.

When the above-mentioned chain saw is working, the power device 110 drives the cutting member 120 to trim the branches. When the work is completed, the handle 130 is rotated to a position coincident with the cutting member 120 , and the cutting member 120 is stored in the handle 130 . In the above chain saw, the handle 130 can be folded, which saves space during transportation and storage, and the cutting part 120 is stored in the accommodation cavity of the handle 130, which will not hurt people and is safe to store.

The above-mentioned embodiments only express several implementations of the utility model, and the description thereof is relatively specific and detailed, but it should not be construed as limiting the patent scope of the utility model. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the scope of protection of the utility model patent should be based on the appended claims.
