[0061] Before any embodiments of the application are explained in detail, it is to be understood that the application is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the following drawings. It is being understood that the same are merely exemplary and explanatory.

[0062] In this application, the terms "comprise", "comprising", "include", "including", "have", "has", "contain", "containing", or any other similar phrase are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus. An element proceeded by "comprises... a" does not, without more constraints, exclude the presence of additional identical elements in the process, method, article, or apparatus that comprises the element.

[0063] ​​​​In the present application, the term "and / or", is a description of an associated relationship with associated objects, which means that there can be three kinds of relationships. For example, A and / or B, can represent: the existence of A alone, the existence of A and B together, and the existence of B alone. In addition, the character " / " in the present application generally indicates that the front and rear associated objects are in a "and / or" relationship.

[0064] In the present application, the terms "connected", "combined", "coupled", "mounted" can be direct connection, combination, coupling or mounting, or indirect connection, combination, coupling or mounting. Among them, for example, direct connection refers to the connection of two parts or components without the need for an intermediate part, while indirect connection refers to the connection of two parts or components with at least one intermediate part. In addition, "connection" and "coupling" are not limited to physical or mechanical connection or coupling, and can include electrical connection or coupling.

[0065] In the present application, those of ordinary skill in the art will understand that the relative terms used in connection with quantities or conditions (for example, "about", "approximately", "substantially" and the like) include the values described and have the meaning indicated by the context. For example, the relative terms at least include the degree of error related to the measurement of a specific value, the tolerance caused by manufacturing, assembly, use, etc. related to a specific value. Such terms should also be considered to disclose the range defined by the absolute values of the two endpoints. The relative term can refer to a certain percentage (e.g. 1%, 5%, 10% or more) of the indicated value. The numerical value without the relative term should also be disclosed as a specific value with a tolerance. In addition, "substantially" when expressing the relative angular positional relationship (for example, substantially parallel, substantially perpendicular), can refer to a certain number of degrees (e.g. 1 degree, 5 degrees, 10 degrees or more) added or subtracted from the indicated angle.

[0066] In the present application, those of ordinary skill in the art will understand that the functions performed by the components can be performed by one component, multiple components, one part, or multiple parts. Similarly, the functions performed by the parts can also be performed by one part, one component, or multiple parts in combination.

[0067] In the present application, the terms "upper", "lower", "left", "right", "front", "back" and the like are described in the orientation and positional relationship shown in the drawings, and should not be understood as a limitation on the embodiments of the present application. In addition, it is also understood in the context that when referring to one element connected to another element "on" or "under", it can be directly connected to another element "on" or "under" or indirectly connected to another element "on" or "under" through an intermediate element. It should also be understood that the terms "upper", "lower", "left", "right", "front", "back" and the like not only represent the positive direction, but also can be understood as the side direction. For example, the lower side can include the directly below, left below, right below, front below and back below, etc.

[0068] At present, the existing bar saw 100a includes an oil pot, the oil pot includes an oil filling port and a pot cover, the oil filling port and the pot cover are matched by threads, the pot cover seals the oil filling port based on the threads, so that the lubricant can be stored in the oil pot. As shown in Figure 1 When the cutting object 100b is located on the upper side of the bar saw 100a, the cutting object 100b will move relative to the bar saw 100a as the bar saw 100a cuts, and there is a probability of touching the oil pot. Further, the cutting object 100b will move relative to the oil pot, and in the process of repeated movement, the pot cover has a probability of rotating relative to the oil filling port, so that the threads matched by the pot cover and the oil filling port are loose, the pot cover is detached from the oil filling port, and the lubricant stored in the oil pot leaks out, so that the bar saw 100a is difficult to continue normal work. Based on this, the present application proposes a bar saw 100, the stability of the pot cover matched with the oil filling port is good, and the probability of accidental rotation and loosening of the pot cover relative to the oil filling port is reduced.

[0069] As shown in Figures 2 to 4 A handheld cutting tool of an embodiment of the present application is shown, in the embodiment, the handheld cutting tool is a bar saw 100. It can be understood that the bar saw 100 is a handheld cutting tool including an oil pot, in other alternative embodiments, the handheld cutting tool can be other handheld cutting tools including an oil pot, such as a chain saw. In order to clearly illustrate the technical solutions of the present application, the upper side, the lower side, the left side, the right side, the front side and the back side as shown in Figure 2 are defined.

[0070] As shown in Figures 2 to 5 The bar saw 100 includes a connecting rod 110, a head 120 and a tail 130, the head 120 and the tail 130 are distributed at both ends of the connecting rod 110 and are connected by the connecting rod 110. Among them, the head 120 is located at the front end of the bar saw 100, and the tail 130 is located at the back end of the bar saw 100.

[0071] The machine head 120 comprises a machine shell 140, a motor 150, a saw chain 160, a guide plate 170 and an oil pot 180. The motor 150 is supported by the machine shell 140 and arranged inside the machine shell 140 to drive the saw chain 160 to perform a cutting function. The saw chain 160 is arranged around the guide plate 170, and the guide plate 170 supports and guides the saw chain 160 so that the saw chain 160 can rotate around the guide plate 170 to achieve cutting. The guide plate 170 extends along the front-rear direction. The oil pot 180 is supported by the machine shell 140 and used to store lubricant to lubricate the saw chain 160 or the guide plate 170. The oil pot 180 comprises a pot body 181, a filling port 182 and a pot cover 183. The filling port 182 is formed on the pot body 181 and used to inject lubricant into the pot body 181. The pot cover 183 cooperates with the filling port 182 to seal the filling port 182 so that the lubricant cannot flow out of the oil pot 180.

[0072] The machine tail 130 is provided with a handle 131 located at the rear end of the pole saw 100. The handle 131 is a main handle 131 for a user to hold and operate the pole saw 100. The pole saw 100 further comprises a secondary handle 132 arranged on the connecting rod 110 between the machine head 120 and the machine tail 130, and the secondary handle 132 is close to the main handle 131 so that the user can hold the secondary handle 132 with the other hand when holding the main handle 131 with one hand, thereby improving the stability of the user holding and operating the pole saw 100.

[0073] As shown in Figure 3 The pole saw 100 further comprises a power supply assembly 133 for supplying power to the motor 150. The power supply assembly 133 is arranged at the machine tail 130, and the machine tail 130 is formed with a connecting portion cooperating with the power supply assembly 133, and the power supply assembly 133 is detachably connected to the connecting portion. The power supply assembly 133 and the machine head 120 are respectively arranged at the two ends of the connecting rod 110, so that the overall weight of the pole saw 100 is balanced. In this embodiment, the power supply assembly 133 comprises a direct current power supply, for example, a battery pack 133. The battery pack 133 cooperates with a corresponding power supply circuit to supply power to the corresponding components in the pole saw 100. Those skilled in the art should understand that the power supply assembly 133 is not limited to the scenario of using the battery pack 133, and can also be powered by mains or alternating current power supply, cooperating with a corresponding rectifier, filter and voltage regulator circuit to supply power to the corresponding components in the machine. In this embodiment, the direct current power supply is specifically arranged as the battery pack 133, and the battery pack 133 will be used instead of the direct current power supply hereinafter, but it cannot be regarded as a limitation of the present application.

[0074] In some embodiments, as Figure 6As shown, an oil inlet thread 1821 is formed on the oil inlet 182, and a lid thread (not shown in the figure) is formed on the lid 183 to mate with the oil inlet thread 1821. Thus, the lid 183 and the oil inlet 182 can mate with each other based on the oil inlet thread 1821 and the lid thread, so that the lid 183 can rotate to seal the oil inlet 182, preventing the lubricant stored in the oil can 180 from leaking out from the oil inlet 182.

[0075] In some embodiments, such as Figure 7 As shown, in the vertical direction, the oil inlet 182 is located on the upper part of the pot body 181. The oil inlet 182 is in a slightly upper position on the pot body 181, that is, the oil inlet 182 is in a slightly upper position on the entire bar saw 100. Therefore, when the bar saw 100 is in Figure 2 In the operating state shown, if the lubricant in the oil reservoir 180 needs to be replenished, the user only needs to tilt the bar saw 100 at a certain angle, rotate the reservoir cap 183 away from the oil inlet 182, and then directly add the lubricant into the oil reservoir 180. Furthermore, because the oil inlet 182 is positioned slightly upwards, the reservoir 181 can hold a larger amount of lubricant without leakage when adding it. If the oil inlet 182 were located in the middle or lower part of the reservoir 181 in the vertical direction, the user would need to lay the bar saw 100 flat so that the oil reservoir 180 is almost parallel to the horizontal plane to replenish the lubricant. Otherwise, if only tilted at a certain angle, the lubricant may leak from the oil inlet 182, and directly replenishing the lubricant would be inconvenient. Therefore, in this application, the oil filling port 182 is located on the upper part of the pot body 181, which not only improves the convenience for users to directly add lubricant during use, but also ensures the storage capacity of the oil pot 180 when adding lubricant to the tilt bar saw 100.

[0076] In some embodiments, such as Figure 7 As shown, the distance X1 between the lid 183 and the top of the housing 140 is greater than or equal to 0 mm and less than or equal to 15 mm. A smaller distance X1 means the oil inlet 182 is positioned slightly above the top of the pot body 181. Specifically, distance X1 is the distance between the topmost point of the lid 183 and the top of the housing 140. Optionally, the distance X1 between the lid 183 and the top of the housing 140 is 3 mm. Optionally, the distance X1 between the lid 183 and the top of the housing 140 is 4.5 mm. Optionally, the distance X1 between the lid 183 and the top of the housing 140 is 6 mm. Optionally, the distance X1 between the lid 183 and the top of the housing 140 is 6.6 mm. Optionally, the distance X1 between the lid 183 and the top of the housing 140 is 12 mm. Optionally, the distance X1 between the lid 183 and the top of the housing 140 is 13.7 mm. In some embodiments, a protrusion 184 is formed on the body 181, such as... Figures 2 to 4As shown, the protrusion 184 can cover at least a portion of the lid 183, and the protrusion 184 is disposed radially outward around at least a portion of the lid 183. Optionally, the protrusion 184 is integrally formed with the pot body 181, and the protruding protrusion 184 is formed directly from the pot body 181. Optionally, the protrusion 184 is separately disposed from the pot body 181, and the protrusion 184 is formed separately and fixedly connected to the pot body 181.

[0077] like Figure 8a and Figure 8b As shown, a protrusion 184 is disposed on the upper side of the lid 183, and the protrusion 184 extends and protrudes along the axial direction of the body 181, that is, the protrusion 184 extends and protrudes along the left and right direction. Since the lid 183 protrudes relative to the body 181 in the left and right direction, and the protrusion 184 is disposed along the radial outer side of the lid 183, the protrusion 184 can at least partially cover the lid 183 in the front-back direction and the top-bottom direction. This application does not limit the shape of the protrusion 184; the protrusion 184 can be any shape that can provide a certain degree of coverage. Optionally, the protrusion 184 can also be disposed around the front half of the lid 183. Optionally, the protrusion 184 can also be disposed around the upper half of the lid 183. Optionally, the protrusion 184 can also be disposed around the entire circumference of the lid 183, thereby more comprehensively preventing the lid 183 from contacting the object to be cut and being rotated. This application does not limit the specific details of how the protrusion 184 surrounds the lid 183, as long as the protrusion 184 can at least cover part of the front and part of the top of the lid 183.

[0078] In some embodiments, the protrusion 184 extends from the body 181 toward the top 1831 of the lid 183 beyond the base 1832 of the lid 183, meaning that in the left-right direction, the protrusion 184 at least partially covers the lid 183, and the protruding length of the protrusion 184 is less than the width of the lid 183. In some embodiments, the protrusion 184 extends from the body 181 toward the top 1831 of the lid 183 beyond the top 1831 of the lid 183, meaning that in the left-right direction, the protrusion 184 completely covers the lid 183, and the protruding length of the protrusion 184 is greater than or equal to the width of the lid 183. Wherein, as... Figure 8a and Figure 8b As shown, the root 1841 of the protrusion 184 may be more offset to the left of the bar saw 100 than the root 1832 of the lid 183. Optionally, the root 1841 of the protrusion 184 may also be more offset to the right of the bar saw 100 than the root 1832 of the lid 183. Optionally, the root 1841 of the protrusion 184 may also be on the same vertical plane extending in the front-back direction as the root 1832 of the lid 183.

[0079] In some embodiments, the upper end 1842 of the protrusion 184 is flush with the top 185 of the oil can 180 in the up-down direction. In some embodiments, the upper end 1842 of the protrusion 184 is lower than the top 185 of the oil can 180 in the up-down direction. As shown in FIG. 1 8, the upper end 1842 of the protrusion 184 is not higher than the top 185 of the oil can 180 in the up-down direction. Thus, the structure of the oil can 180 with the protrusion 184 is simple, and the processing technology in the manufacturing process is simple. In some embodiments, as shown in FIG. 1 9, the thickness X2 of the protrusion 184 is less than or equal to 5 mm. In some embodiments, the thickness X2 of the protrusion 184 is 1.5 mm. In some embodiments, the thickness X2 of the protrusion 184 is 2.3 mm. In some embodiments, the thickness X2 of the protrusion 184 is 3 mm. In some embodiments, the thickness X2 of the protrusion 184 is 4.8 mm. In some embodiments, as shown in FIG. 20, the gap X3 between the lid 183 and the protrusion 184 is less than or equal to 10 mm, and the gap X3 between the lid 183 and the protrusion 184 is greater than 0 mm because the lid 183 needs to be rotated and removed from the oil injection port 182. Figure 9 Figure 9 Figure 9

[0080] Thus, by limiting the thickness X2 of the protrusion 184 and the gap X3 between the lid 183 and the protrusion 184, the thickness X2 of the protrusion 184 is thin, and the gap X3 between the lid 183 and the protrusion 184 is small. This avoids the problem that the thickness X2 of the protrusion 184 is thick and the gap X3 between the lid 183 and the protrusion 184 is too small, making it difficult to rotate and remove the lid 183 from the oil injection port 182. This also avoids the problem that the thickness X2 of the protrusion 184 is thick, causing a cavity to be formed in the protrusion 184, which cannot store lubricant and wastes the space of the oil can 180. At the same time, it also avoids the problem that the gap X3 between the lid 183 and the protrusion 184 is too large and the thickness X2 of the protrusion 184 is thick, causing the protrusion 184 to exceed the top 185 of the oil can 180, making the processing technology complex and the production difficult.

[0081] ​​​The application forms the protruding portion 184 on the kettle body 181, so that when the oil inlet 182 and the kettle cover 183 are located on the upper part of the pole saw 100, if the cutting object is located on the upper side of the saw chain 160, the cutting object will contact the protruding portion 184, the protruding portion 184 blocks the cutting object from contacting the kettle cover 183, or even if the cutting object contacts the kettle cover 183, the cutting object is also difficult to drive the kettle cover 183 to rotate based on the protruding portion 184. Thus, the probability of the kettle cover 183 being contacted by the cutting object and being driven to loosen and fall off from the oil inlet 182 is reduced, and the stability of the cooperation between the kettle cover 183 and the oil inlet 182 is greatly improved.

[0082] The pole saw 100 further comprises a stopper 190, which is arranged on the top end of the machine shell 140 or on the oil kettle 180. In the extension direction of the guide plate 170, that is, in the front-rear direction, the frontmost end of the stopper 190 is located on the front side of the center O of the kettle cover 183, wherein the center O of the kettle cover 183 is the geometric center of the kettle cover 183, that is, the geometric center of the surface of the kettle cover 183. Alternatively, the surface of the kettle cover 183 can be a horizontal plane. Alternatively, the surface of the kettle cover 183 can be a concave-convex plane. Then the geometric center of the surface of the kettle cover 183 is as follows: as shown in the figure, a vertical plane M extending along the front-rear direction and passing through the surface of the kettle cover 183, and the geometric center O of the projection of the surface of the kettle cover 183 on the vertical plane M is the center O of the kettle cover 183. Thus, when the pole saw 100 cuts the cutting object, in the front-rear direction, the cutting object will first contact the stopper 190. And the stopper 190 will prevent the cutting object from contacting the kettle cover 183, or the cutting object can contact the kettle cover 183, but the stopper 190 prevents the cutting object from driving the kettle cover 183 to rotate relative to the oil inlet 182. Figure 10

[0083] In some embodiments, when the stopper 190 is arranged on the kettle body 181, it extends from the kettle body 181 to the top 1831 of the kettle cover 183 beyond the root 1832 of the kettle cover 183, at which time the stopper 190 is the protruding portion 184. As shown in the figure, in the front-rear direction, the frontmost end of the protruding portion 184 is located on the front side of the center O of the kettle cover 183. Wherein, the specific structure and related attributes of the stopper 190 at this time are the same as those of the protruding portion 184 described above in the application, which will not be described here. Figure 10

[0084] In some embodiments, when the stopper 190 is arranged on the top end of the machine shell 140, as shown in the figure, the stopper 190 is a protruding structure 191 extending along the up-down direction. In the front-rear direction, the frontmost end of the protruding structure 191 is located on the front side of the center O of the kettle cover 183. Alternatively, the protruding structure 191 can be Figure 10 Figure 10 ​​​The protruding structure 191 is shown to be arranged almost perpendicularly to the housing 140. Alternatively, the protruding structure 191 can also be arranged at an angle to the housing 140, which is not limited in the present application. Alternatively, the protruding structure 191 can be a rectangular structure as shown. Figure 10 Alternatively, the protruding structure 191 can include a partially serrated structure at the front end in the front-rear direction. Alternatively, the protruding structure 191 can also be any other shape that can block the cutting object, which is not limited in the present application. In addition, the present application does not limit the height H of the protruding structure 191 extending along the up-down direction. The height H of the protruding structure 191 can be any height that can block the cutting object.

[0085] In some embodiments, only one stopper 190 can be arranged on the bar saw 100, and the bar saw 100 is provided with the protrusion 184 or the protruding structure 191. In some embodiments, two stoppers 190 can be arranged on the bar saw 100, and the bar saw 100 is provided with the protrusion 184 and the protruding structure 191.

[0086] In some embodiments, the lid 183 includes a flap 1833 and a body 1834, and the flap 1833 is arranged at the upper half of the lid 183. The flap 1833 can be flipped open relative to the body 1834 to the open state as shown. Figure 11 When the flap 1833 is in the open state, the body 1834 still cooperates with the oil filling port 182 to seal the oil filling port 182, and at this time the flap 1833 is not blocked by the protrusion 184. The present application does not limit the angle A at which the flap 1833 is flipped open relative to the body 1834, which can be 30 degrees, 60 degrees, 90 degrees, etc. Thus, when the user needs to add lubricant to the oil can 180, the user can flip open the flap 1833 and hold the rotating flap 1833 to drive the body 1834 to rotate relative to the oil filling port 182, which facilitates the user to rotate and take off the lid 183 from the oil filling port 182.

[0087] In some embodiments, the flap 1833 is provided with a rotation stopper 1835, and the upper part of the body 1834 is provided with a fixing member 1836 cooperating with the rotation stopper 1835, so that when the flap 1833 is in the open state as shown. Figure 9The stopper 1835 can cooperate with the fixing part 1836 to lock the cover 183 in the closed state, so that the cover 183 cannot be rotated. When the force is applied to the cover 1833 along the left and right directions to make the stopper 1835 and the fixing part 1836 disengage, the cover 1833 is in the open state, and the cover 183 can be rotated. In addition, the fixing part 1836 can also be arranged on the kettle body 181 at other positions capable of cooperating with the stopper 1835, or the fixing part 1836 can also be arranged on the machine shell 140 at positions capable of cooperating with the stopper 1835, which is not limited in the present application.

[0088] In some embodiments, as shown in Figure 12a and Figure 12b The stopper 1835 is a recess, and the fixing part 1836 is a matching protruding component, which cooperates to prevent the cover 183 from rotating. In some embodiments, the stopper 1835 can be a protruding component, and the fixing part 1836 is a matching recess, which cooperates to prevent the cover 183 from rotating. In addition, the stopper 1835 and the fixing part 1836 can also be other components that cooperate to prevent the cover 183 from rotating, which is not limited in the present application.

[0089] Therefore, when the stopper 1835 is arranged on the cover 1833, as shown in Figure 12c When the cover 1833 is in the closed state, the oil canister 180 does not need to be provided with the stopper 190, and even if the cover 183 contacts the object to be cut at this time, the object to be cut cannot drive the cover 183 to rotate, which improves the stability of the cooperation between the cover 183 and the oil inlet 182. Alternatively, the rod saw 100 is provided with the stopper 190 and the stopper 1835 on the cover 1833 at the same time, which further improves the stability of the cooperation between the cover 183 and the oil inlet 182.

[0090] The basic principles, main features and advantages of the present application are shown and described above. Those skilled in the art should understand that the above embodiments do not limit the present application in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation fall within the protection scope of the present application.
