[0039] Refer to Figure 1 and Figure 2 , FIG. 1 shows a schematic diagram of the overall structure of a sawing tool in an embodiment of the present application. Figure 2 shows a schematic diagram of the internal structure of a barrel part in an embodiment of the present application. An embodiment of the present application provides a sawing tool, including a housing 1, a motor 2, a transmission mechanism 3, a tool accessory 4, and a toggling member 5. Among them, the housing 1 includes a main body part, and a barrel part 11 and a clamping part 12 are formed on the main body part. The barrel part 11 and the clamping part 12 can be installed on the main body part or integrally formed on the main body part. In the embodiment of the present application, the barrel part 11 and the clamping part 12 are preferably integrally formed on the main body part.

[0040] The motor 2 is installed in the housing 1, and may be partially exposed or completely contained in the housing 1. The motor 2 is used to receive energy to output power. The transmission mechanism 3 is connected to the motor 2, and the transmission mechanism 3 receives the power of the motor 2 and transmits the power to the output shaft of the transmission mechanism 3. The saw blade can be installed on the output shaft through the tool attachment 4, and the tool attachment 4 can have a first end 41 and a second end 42, and the extension lines of the first end 41 and the second end 42 are perpendicular to each other.

[0041] The first end 41 of the tool accessory 4 is located in the barrel 11, and the second end 42 is connected to the clamping portion 12, so that the tool accessory 4 can be installed on the main body of the housing 1. Preferably, the tool accessory 4 can be an inner hexagonal wrench. The inner hexagonal wrench is installed on the housing 1, which is convenient to carry and reduces the probability of loss.

[0042] See also Figure 2 and Figure 3 FIG3 shows an enlarged schematic diagram of the barrel structure in an embodiment of the present application. The toggle member 5 can be mounted on the barrel 11 and one end can be located inside the barrel 11. When the tool accessory 4 is in the unlocked state, the toggle member 5 abuts against the first end 41, thereby pushing the tool accessory 4 out of the clamping and fixing of the clamping portion 12, thereby facilitating the removal of the tool accessory 4. When the tool accessory 4 is in the locked state, there can be a certain distance between the end of the toggle member 5 and the first end 41. Of course, those skilled in the art can understand that when the tool accessory 4 is in the locked state, the end of the toggle member 5 can also fit or contact the first end 41. Only when the tool accessory 4 needs to be switched to the unlocked state, the toggle member 5 abuts against the first end 41, that is, there is a thrust force to facilitate unlocking the tool accessory 4.

[0043] In one or other preferred embodiments, the end of the toggle member 5 away from the first end 41 may further extend out of the barrel 11, and the end of the toggle member 5 away from the first end 41 extending out of the barrel 11 may serve as the operating end 6. In addition, preferably, the operating end 6 may be connected to the portion of the toggle member 5 away from the first end 41 extending out of the barrel 11, or the operating end 6 may be directly connected to the end of the toggle member 5 away from the first end 41, and the operating end 6 extends into the barrel 11 and is connected to the toggle member 5.

[0044] See also Figure 3 and Figure 44 shows an enlarged schematic diagram of the barrel structure in another embodiment of the present application. In one or other preferred embodiments, when the tool accessory 4 is in a locked state, the height of the operating end 6 protruding from the housing 1 is less than or equal to the length of the operating end 6. At this time, the locked state should be that the tool accessory 4 is embedded in the barrel 11, and the sawing tool can be in a working state. The height of the operating end 6 protruding from the housing 1 is less than or equal to the length of the operating end 6, so that the operating end 6 does not protrude too much, thereby reducing the impact on the normal operation of the sawing tool and / or reducing the obstruction to the user's hand.

[0045] In one or other preferred embodiments, the operating end 6 can be fixedly connected to the toggle member 5, the extension direction of the operating end 6 can be consistent with the toggle member 5, and the extension direction of the operating end 6 can also be tilted, for example, tilted toward the direction of the second end 42 of the tool accessory 4, or tilted toward the main body of the shell 1, as long as the height of the operating end 6 protruding from the shell 1 is less than or equal to the length of the operating end 6.

[0046] In particular, the extension direction of the operating end 6 can be parallel to the extension direction of the barrel 11, that is, the extension direction of the operating end 6 is parallel to the length direction of the first end 41, as long as the distance between the operating end 6 and the barrel 11 is sufficient to drive the toggle member 5 to push the tool accessory 4 out of the barrel 11.

[0047] See also Figure 4 and Figure 5 5 shows an enlarged schematic diagram of the barrel structure in another embodiment of the present application. In one or other preferred embodiments, the toggle member 5 can be rotatably connected to the barrel 11. Specifically, the toggle member 5 can be pivoted on the barrel 11, thereby facilitating the operation of the tool accessory 4 through the lever principle.

[0048] In one or other preferred embodiments, the ratio of the force arm of the operating end 6 to the force arm of the toggle member 5 close to the first end 41 is at least 1. Preferably, the ratio of the force arm of the operating end 6 to the force arm of the toggle member 5 close to the first end 41 is greater than 1, thereby making the operation of the operating end 6 more labor-saving.

[0049] In one or other preferred embodiments, the above-mentioned sawing tool also includes a limiting portion 7, which is located on the side of the operating end 6 away from the second end 42. The limiting portion 7 can be located on the operating end 6 or on the toggle member 5. When the tool accessory 4 is in an unlocked state, the limiting portion 7 abuts against the side wall of the operating end 6 or the toggle member 5, thereby limiting the position of the operating end 6 and transmitting the force applied to the operating end 6 to the toggle member 5.

[0050] Specifically, the limiting part 7 can be located at the rotational connection between the operating end 6 and the barrel part 11, and the limiting part 7 can protrude from the rotational connection between the operating end 6 and the barrel part 11; if the limiting part 7 is located on the operating end 6, when the tool accessory 4 is in the unlocked state, the limiting part 7 abuts against the toggling part 5, thereby driving the toggling part 5 to rotate; if the limiting part 7 is located on the toggling part 5, when the tool accessory 4 is in the unlocked state, the limiting part 7 abuts against the operating end 6, thereby driving the toggling part 5 to rotate.

[0051] Refer to Figure 6 and Figure 7 , Fig. 6 shows a schematic diagram of the structure around the barrel part in another embodiment of the present application, and Fig. 7 shows an enlarged schematic diagram of the structure around the tool accessory in an embodiment of the present application. In one or other preferred embodiments, a positioning part 61 is provided on the operating end 6, and a fixing part 111 is provided on the barrel part 11. When the tool accessory 4 is in the locked state, the positioning part 61 cooperates with the fixing part 111. Among them, one of the positioning part 61 and the fixing part 111 can be a convex block, and the other can be a concave hole. The convex block can be inserted into the concave hole to fix the position of the operating end 6. In the embodiment of the present application, the positioning part 61 is preferably a concave hole, and the fixing part 111 is preferably a convex block to facilitate clamping and fixing of the operating end 6.

[0052] Refer to Figure 2 and Figure 8 , Fig. 8 shows a schematic diagram of the structure around the clamping part in an embodiment of the present application. In one or other preferred embodiments, the clamping part 12 includes an extending part 121 and a stopping part 122. The extending part 121 can be integrally formed on the main body part or can be installed on the main body part. The stopping part 122 can be integrally formed on the extending part 121 or can be installed on the extending part 121. In the embodiment of the present application, the extending part 121 and the stopping part 122 are integrally formed and integrally formed on the main body part. The extending part 121 can be plate-shaped, and the stopping part 122 can be a hemispherical or triangular protrusion. When the working accessory is installed on the clamping part 12, the working accessory abuts against the stopping part 122, pushing the extending part 121 to move in a direction away from the working accessory. When the tool accessory 4 passes over the stopping part 122, the extending part 121 is restored under the elastic force to clamp and fix the tool accessory 4.

[0053] Preferably, there can be two clamping parts 12, and the two clamping parts 12 are arranged oppositely, that is, the stopping parts 122 of the two clamping parts 12 both face the tool accessory 4. The two clamping parts 12 can be arranged in alignment or staggered. Of course, there can also be three or more clamping parts 12, and the clamping parts 12 can be arranged in a staggered manner, so as to be more convenient for fixing the tool accessory 4.

[0054] Preferably, the vertical distance L between two opposite said stoppers 122 is less than the maximum value D of the external dimensions of the tool attachment 4. Here, the vertical distance L refers to the distance between the parallel line extending from one of the stoppers 122 to the corresponding position of the other stopper 122 and the corresponding stopper 122.

[0055] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0056] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application.
