Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power tools, in particular to a housing assembly of a power tool and the power tool. BACKGROUND

[0002] In construction, manufacturing and assembly operations, material workpieces, such as wood, plastic and metal (i.e. workpieces to be processed) must be cut to precise lengths, shapes and dimensions. In many cases, power tools are used to cut these workpieces. For example, the power tool is a miter saw, which for example includes a base member, a mounting bracket and an output saw assembly mounted to the mounting bracket. In order to improve the safety of using the miter saw, a stop pin is often arranged on the base member, and the stop pin is used to prevent the mounting bracket from rotating relative to the base member during the cutting process of the workpiece to be processed placed on the base member by the output saw assembly, so as to prevent the output saw assembly from directly impacting the base member.

[0003] Specifically, since the rotating connection between the mounting bracket and the base member is provided with a spring for making the output saw assembly move away from the base member, the end of the mounting bracket away from the base member is tilted away from the base member, so that when the housing assembly of the miter saw is packaged, a packaging box with a large height volume needs to be provided, thereby increasing the packaging cost, and increasing the transportation volume, and further reducing the transportation efficiency. SUMMARY

[0004] The present application solves the technical problem that due to the rotating connection between the mounting bracket and the base member being provided with a spring for making the output saw assembly move away from the base member, the end of the mounting bracket away from the base member is tilted away from the base member, so that when the housing assembly of the miter saw is packaged, a packaging box with a large height volume needs to be provided, thereby increasing the packaging cost, and increasing the transportation volume, and further reducing the transportation efficiency.

[0005] To solve the above problems, the present application provides a housing assembly of a power tool, comprising: a base member; a mounting bracket, the mounting bracket being movably connected with the base member; a locking member, the locking member being mounted on any one of the base member and the mounting bracket, and the locking member being further used to connect the other one of the base member and the mounting bracket; wherein when the mounting bracket is in a locked state by the locking member, a first overall height formed by the combination of the base member and the mounting bracket is less than at least one second overall height in an unlocked state.

[0006] Compared with the prior art, the technical effects achieved by adopting the technical scheme are as follows: in order to facilitate understanding, the mounting bracket is divided into a mounting end part and a connecting end part, the mounting end part is used for mounting the output saw assembly, the connecting end part is connected with the base part, the base part and the mounting bracket are simultaneously connected by the locking part to make the mounting bracket in a locked state, at this time, compared with a conventional state, i.e., an unlocked state, the distance formed between the base part and the mounting end part is reduced, i.e., the distance between the base part and the mounting end part is shortened, so that the overall height of the second whole machine is reduced to the first overall height, i.e., the overall height of the whole machine formed by the combination of the base part and the mounting bracket is reduced, thereby the accommodating height of the packaging box is reduced, and the packaging material cost and the packaging cost are reduced.

[0007] In an example of the present application, the locking part is detachably connected with at least one of the base part and the mounting bracket.

[0008] Compared with the prior art, the technical effects achieved by adopting the technical scheme are as follows: in a specific example, in order to facilitate operation, the locking part can be detachably connected with the base part and the mounting bracket, since the locking part is mainly used for resisting the elastic force of the torsional spring, the structure of the locking part is prone to deformation and damage after long-term use, therefore, the locking part is detachable with the base part and the mounting bracket at the same time, so as to facilitate timely replacement of the locking part and ensure that the mounting bracket can be in a stable and reliable locked state.

[0009] In an example of the present application, the base part comprises: a pull rod part, one end of the pull rod part is rotatably connected with the mounting bracket; a machining platform, the machining platform is connected with the other end of the pull rod part, and the mounting bracket is located above the machining platform in the vertical direction; wherein the locking part is used for connecting the pull rod part and the mounting bracket.

[0010] Compared with the prior art, the technical effects achieved by adopting the technical scheme are as follows: by connecting the pull rod part and the mounting bracket through the locking part, the distance between the mounting end part of the mounting bracket and the machining platform can be shortened, and the position of the mounting bracket relative to the machining platform can be adjusted during the sliding of the pull rod part, so as to better package the housing assembly or the miter saw and reduce the packaging difficulty.

[0011] In an example of the present application, the locking part comprises: a first locking part, the first locking part is connected to the base part; a second locking part, the second locking part is connected to the mounting bracket at a position corresponding to the first locking part; wherein when the mounting bracket is in a locked state, the first locking part and the second locking part are inserted, clamped or screwed.

[0012] Compared with the prior art, the technical effects achieved by the technical scheme are: the mutual matching mode of the first locking member and the second locking member is simple and reliable, so that the switching of the mounting bracket between the locked state and the unlocked state is convenient to operate.

[0013] In one example of the present application, the mounting bracket is used for mounting a workpiece; characterized in that the mounting bracket is rotationally connected with the base component to drive the workpiece to approach or move away from the base component; wherein when the mounting bracket rotates relative to the base component, the second locking member is correspondingly arranged in one of the at least one locking position of the first locking member in sequence.

[0014] Compared with the prior art, the technical effects achieved by the technical scheme are: it can be understood that the miter saw can select a workpiece, i.e., a cutting saw blade, of a size that is suitable for the cutting requirements, and often needs to reasonably adjust the distance between the mounting bracket and the machining platform to avoid the size of the cutting saw blade being too large to cause the mounting bracket to fail to smoothly enter the locked state, or the size of the selected cutting saw blade being too small to cause the distance between the mounting end of the mounting bracket and the machining platform to be too large to increase the height of the packaging space and thus increase the packaging cost.

[0015] In one example of the present application, either of the first locking member and the second locking member is a locking rod, and the other is at least one locking hole matched with the locking rod; the housing assembly further comprises: a shielding component for shielding the at least one locking hole.

[0016] Compared with the prior art, the technical effects achieved by the technical scheme are: on the one hand, when the locking rod and the locking hole are separately arranged, the shielding of the locking hole by the shielding component improves the appearance of the housing assembly, and also avoids the machining waste residues generated during the machining process using the miter saw in the unlocked state from being left in the locking hole, which hinders the maintenance of the stable locked state of the subsequent mounting bracket; on the other hand, the shielding of the locking hole by the shielding component limits the accidental insertion of the locking rod into the locking hole during the actual machining process, ensuring the machining process; in addition, the stopping of the locking rod by the shielding component can also avoid the accidental situation of the cutting saw blade hitting the machining platform due to the mounting bracket driving the output saw assembly to be too close to the machining platform.

[0017] In one example of the present application, the first locking member is a locking hole; the shielding component comprises: a shielding member arranged on the base component and used for shielding the locking hole; and a reset member arranged in a mounting groove of the base component and matched with the shielding member; wherein the reset member has an elastic force for maintaining the shielding member to shield the locking hole.

[0018] Compared with the prior art, the technical effects achieved by the technical scheme are as follows: specifically, the reset member can be a reset torsion spring, one end of the reset torsion spring is connected with the matching hole on the shielding member, when it is needed to install the support in the locked state, the user needs to overcome the elastic force of the reset torsion spring to move the shielding member away from the position of the shielding locking hole, so that the locking rod enters the corresponding locking hole. In short, the stability of the shielding member shielding the locking hole is ensured by the elastic force of the reset member.

[0019] In an example of the present application, the part of the shielding member away from the locking hole is provided with a pushing member.

[0020] Compared with the prior art, the technical effects achieved by the technical scheme are as follows: the operation of pushing the pushing member to open the locking hole is more labor-saving and convenient.

[0021] In an example of the present application, the shielding member is rotationally connected to the base part to open or shield the locking hole; when the mounting support is in the unlocked state, the shielding member prevents the second locking member from entering the locking hole.

[0022] Compared with the prior art, the technical effects achieved by the technical scheme are as follows: the smooth progress of the miter saw machining process is further ensured, and the accidental entry of the locking rod into the locking hole is avoided.

[0023] On the other hand, the present application also provides a power tool, comprising: the housing assembly provided in any of the above examples; a driving assembly mounted to the mounting support; a machining member rotationally connected to the driving assembly and driven by the driving assembly.

[0024] Compared with the prior art, the technical effects achieved by the technical scheme are as follows: the corresponding technical effects of any of the above technical schemes can be achieved, which will not be repeated here.

[0025] After adopting the technical scheme of the present application, the following technical effects can be achieved:

[0026] (1) The mounting support is divided into a mounting end part and a connecting end part, the mounting end part is used to install the output saw assembly, the connecting end part is connected with the base part, and the base part and the mounting support are connected by the locking part to make the mounting support in the locked state, at this time, compared with the conventional state, i.e. the unlocked state, the distance formed between the base part and the mounting end part is reduced, i.e. the distance between the base part and the mounting end part is shortened, so that the overall height of the whole machine is reduced from the second overall height to the first overall height, i.e. the overall height formed by the combination of the base part and the mounting support is reduced, thereby realizing the reduction of the accommodation height of the packaging box, and further reducing the packaging material cost and the packaging cost.

[0027] (2) On one hand, when the locking rod is separated from the locking hole, the locking hole is shielded by the shielding component to improve the appearance of the shell assembly, and also avoid the machining waste generated during the processing by the miter saw in the unlocked state from being left in the locking hole, which hinders the stable locking state of the subsequent installation support; on the other hand, the shielding of the locking hole by the shielding component limits the accidental insertion of the locking rod into the locking hole during actual processing, ensuring the processing process; in addition, the shielding effect of the shielding component on the locking rod can also avoid the accidental situation of the cutting saw blade hitting the processing platform due to the installation support driving the output saw assembly too close to the processing platform.

[0028] (3) Specifically, the reset member can be a reset torsional spring, one end of the reset torsional spring is connected with the matching hole on the shielding component, when the installation support needs to be in the locked state, the user needs to overcome the elastic force of the reset torsional spring to move the shielding component away from the position of shielding the locking hole, so that the locking rod enters the corresponding locking hole. In short, the stability of the shielding component shielding the locking hole is ensured by the elastic force of the reset member. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0037] In order to make the above objectives, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0038] Embodiment one:

[0039] Referring to Figure 1 , which is a structural schematic view of a housing assembly of a power tool according to the embodiment one of the present application. In combination with Figures 2-6 , the housing assembly comprises a base component, a mounting bracket 10 and a locking component 30. The mounting bracket 10 is movably connected with the base component; the locking component 30 is mounted on either one of the base component and the mounting bracket 10, and the locking component 30 is also used to connect the other one of the two; wherein when the mounting bracket 10 is in a locked state by the locking component 30, the first overall height formed by the combination of the base component and the mounting bracket 10 is less than at least one second overall height in an unlocked state.

[0040] In one specific example, the power tool is a miter saw 100, and the mounting bracket 10 is used to mount an output saw assembly 110 of the miter saw 100. Commonly, the mounting bracket 10 is rotatably connected with the base component, and the output saw assembly 110 has a large weight due to the inclusion of parts such as a motor and a cutting saw blade. In combination with the mounting position characteristics of the output saw assembly 110 on the mounting bracket 10, i.e. the output saw assembly 110 is mounted to the end of the mounting bracket 10 away from the base component, the mounting bracket 10 will move towards the workpiece placement end face of the base component under the action of gravity. Therefore, in order to avoid the output saw assembly 110 from colliding with the base component, a torsion spring is often arranged at the position where the mounting bracket 10 is rotatably connected with the base component. The elastic force of the torsion spring causes the end of the mounting bracket 10 provided with the output saw assembly 110 to move towards the direction away from the workpiece placement end face, i.e. the end is raised relative to the base component and is at a higher position of the entire power tool.

[0041] Further, in combination with the actual packaging situation, the end of the mounting bracket 10 away from the base component is the highest point of the entire power tool when it is normally placed on a horizontal table top, i.e. the distance between the end and the base 213 in the base component is the largest. Due to the above-mentioned situation that the end of the mounting bracket 10 is raised under the action of the torsion spring, the required accommodation height for packaging the entire miter saw 100 is increased. If the output saw assembly 110 is not mounted on the mounting bracket 10, the end of the mounting bracket 10 away from the base 213 assembly will be further raised, thereby further increasing the height of the packaging box required for packaging. Therefore, it means that the cost of the required packaging is increased.

[0042] Therefore, in order to facilitate understanding, the mounting bracket 10 is divided into a mounting end portion 11 and a connecting end portion 12. The mounting end portion 11 is used for mounting the output saw assembly 110, and the connecting end portion 12 is connected with the base 213. The locking component 30 is used for simultaneously connecting the base 213 and the mounting bracket 10 to make the mounting bracket 10 in a locked state. Compared with a conventional state, i.e., an unlocked state, the distance between the base 213 and the mounting end portion 11 is reduced, i.e., the distance between the base component and the mounting end portion 11 is shortened, so that the overall height of the power tool is reduced from a second overall height to a first overall height, i.e., the overall height of the power tool formed by the base component and the mounting bracket 10 is reduced, thereby reducing the accommodating height of the packaging box, further reducing the packaging material cost, and reducing the packaging cost. In order to facilitate understanding, the overall height is denoted by H.

[0043] Briefly, the larger the distance between the mounting end portion 11 and the base component, the larger the overall height of the power tool.

[0044] Preferably, the locking component 30 is detachably connected with at least one of the base component and the mounting bracket 10.

[0045] In a specific example, in order to facilitate operation, the locking component 30 is detachably connected with both the base 213 and the mounting bracket 10. Since the locking component 30 is mainly used for resisting the elastic force of the torsional spring mentioned above, the structure of the locking component 30 is prone to deformation and damage after long-term use. Therefore, the locking component 30 is detachably connected with both the base 213 and the mounting bracket 10, so as to facilitate timely replacement of the locking component 30 and ensure that the mounting bracket 10 can be in a stable and reliable locked state.

[0046] Further, the base component includes a pull rod 22 and a processing platform 21. One end of the pull rod 22 is rotatably connected with the mounting bracket 10. The processing platform 21 is connected with the other end of the pull rod 22, and the mounting bracket 10 is located above the processing platform 21 in the vertical direction. The locking component 30 is used for connecting the pull rod 22 and the mounting bracket 10.

[0047] In a specific example, the pull rod 22 and the processing platform 21 are in sliding connection. Specifically, the pull rod 22 and the processing platform 21 are used for maintaining parallel arrangement between the processing end face of the to-be-processed piece, i.e., when the pull rod 22 slides relative to the processing platform 21, the distance between the pull rod 22 and the processing end face remains unchanged. During the movement, the pull rod 22 drives the mounting bracket 10 to move above the processing platform 21.

[0048] Further, by connecting the pull rod member 22 and the mounting bracket 10 through the locking member 30, the distance between the mounting end 11 and the processing platform 21 can be reduced, that is, the height H of the entire machine is reduced, and the position of the mounting bracket 10 relative to the processing platform 21 can be adjusted during the sliding of the pull rod member 22, so that the housing assembly or the miter saw 100 is better packaged, and the packaging difficulty is reduced.

[0049] Specifically, the processing platform 21 includes a base 213, a rotating platform 211, and an extension table 212. The base 213 is provided with a mounting surface, and one end of the base 213 is slidably connected to the corresponding end of the pull rod member 22. When the pull rod member 22 is adjusted to slide relative to the base 213, the mounting bracket 10 connected to the pull rod member 22 is driven to move above the processing platform formed by the combination of the rotating platform 211 and the extension table 212, so that the processing piece mounted on the mounting bracket 10 can cut the different positions of the workpiece placed on the processing platform. The rotating platform 211 is rotatably connected to the mounting surface. The extension table 212 is arranged adjacent to the rotating platform 211. The extension table 212 and the base 213 are detachably connected. For example, the processing piece is a cutting piece, and the cutting piece is a cutting blade.

[0050] In a specific example, the workpiece is often placed on the rotating platform 211, and different parts of the workpiece are cut by rotating the rotating platform 211. When the size of the workpiece is large, the extension table 212 and the rotating platform 211 are combined to support the workpiece.

[0051] Although the related art has appeared to add the extension table 212 to the base 213 to increase the support of the workpiece, the extension table 212 and the base 213 are often integrally formed, which has the following problems. On the one hand, the overall weight of the miter saw 100 is increased, the user's difficulty in carrying the miter saw 100 is increased, and the portability is reduced. On the other hand, it can be understood that the extension table 212 is often arranged on both sides of the rotating platform 211, so that during the movement of the miter saw 100, the extension table 212 will inevitably collide with other objects in the actual environment. If the damage is serious, the stable support effect of the rotating platform 211 on the workpiece will be affected, and the cutting efficiency of the miter saw 100 on the workpiece will be reduced. For example, the base 213 is made of aluminum.

[0052] Therefore, according to the technical solution, the extension table 212 is detachably connected with the base 213. On the one hand, when the extension table 212 is damaged, for example, the supporting end surface of the extension table 212 for supporting the workpiece is deformed or the end of the extension table 212 away from the rotating platform 211 is deformed to form a protrusion protruding to the supporting end surface, the stable supporting effect of the rotating platform 211 on the workpiece will be affected. In this case, only the extension table 212 needs to be replaced, and the base 213 does not need to be replaced, thereby reducing the replacement cost. On the other hand, during the transportation of the miter saw 100, the extension table 212 can be detached in advance to avoid collision of the extension table 212.

[0053] Preferably, the locking component 30 includes a first locking piece and a second locking piece. The first locking piece is connected to the base 213, and the second locking piece is connected to the mounting bracket 10 at a position corresponding to the first locking piece. When the mounting bracket 10 is in the locked state, the first locking piece and the second locking piece are inserted, clamped, or screwed. The simple and reliable mutual cooperation of the first locking piece and the second locking piece makes it easy to switch the mounting bracket 10 between the locked state and the unlocked state.

[0054] Preferably, the mounting bracket 10 is used for mounting a workpiece. The mounting bracket 10 is rotatably connected to the base 213 to drive the workpiece to approach or move away from the base 213. When the mounting bracket 10 rotates relative to the base 213, the second locking piece is correspondingly arranged in at least one of the locking positions of the first locking piece.

[0055] In a specific example, it can be understood that the miter saw 100 can select a workpiece, i.e., a cutting saw blade, of a size that is suitable for the cutting requirement. The distance between the mounting bracket 10 and the workbench 21 needs to be reasonably adjusted to avoid the size of the cutting saw blade being too large to allow the mounting bracket 10 to be in the locked state, or the size of the cutting saw blade being too small to cause the distance between the mounting end 11 of the mounting bracket 10 and the workbench 21 to be too large, i.e., the height H of the entire machine is too large, thereby increasing the height of the packaging space and increasing the packaging cost.

[0056] Therefore, in combination with the above analysis, a plurality of locking positions can be provided, and the plurality of locking positions are sequentially arranged along the rotation direction of the mounting bracket 10 around the base 213, so that after the mounting bracket 10 is rotated by a certain angle, the second locking member can cooperate with the locking position at the corresponding position at this time, thereby locking the mounting bracket 10 to the corresponding position, and then under the locking effect of the mounting bracket 10, the locking state of the mounting bracket 10 is more refined, so that the distance formed between the mounting end 11 and the base 213 in the locked state can be adjusted according to different models of power tools, thereby reasonably adjusting the overall height H and minimizing the cost of the packaging box.

[0057] Preferably, either of the first locking member and the second locking member is a locking rod 31, and the other is at least one locking hole 32 cooperating with the locking rod 31; the shell assembly further comprises a shielding part 40, for example, for shielding the at least one locking hole 32. Specifically, on the one hand, when the locking rod 31 and the locking hole 32 are arranged separately, shielding the locking hole 32 by the shielding part 40 improves the appearance of the shell assembly, and also avoids the machining waste generated during the machining process of the miter saw 100 from being left in the locking hole 32, which hinders the subsequent maintenance of the stable locking state of the mounting bracket 10; on the other hand, shielding the locking hole 32 by the shielding part 40 limits the accidental insertion of the locking rod 31 into the locking hole 32 during actual machining, ensuring the machining process; in addition, the shielding part 40 can also stop the locking rod 31 to avoid the mounting bracket 10 driving the output saw assembly 110 too close to the machining platform 21, causing the cutting saw blade to hit the machining platform 21.

[0058] It should be noted that, compared to the state where the locking rod 31 enters the locking hole 32 and the state where the locking rod 31 is stopped by the shielding part 40, the mounting end of the mounting bracket 10 in the former state is closer to the machining end face of the machining platform 21.

[0059] Preferably, the first locking member is the locking hole 32; the shielding component 40 comprises a shielding member 41 and a reset member 42. Specifically, the shielding member 41 can be a shielding plate, which is arranged on the base 213 and used to shield the locking hole 32; the reset member 42 is arranged in a mounting groove of the base 213 and cooperates with the shielding member 41; the reset member 42 has an elastic force to maintain the shielding member 41 to shield the locking hole 32. Specifically, the reset member 42 can be a reset torsion spring, one end of which is connected with a cooperating hole on the shielding member 41; when it is needed to install the support 10 in the locked state, the user needs to overcome the elastic force of the reset torsion spring to move the shielding member 41 away from the position of the locking hole 32, so that the locking rod 31 enters the corresponding locking hole 32. In short, the stability of the shielding member 41 to shield the locking hole 32 is ensured by the elastic force of the reset member 42.

[0060] Preferably, the shielding member 41 is provided with a knob 43 away from the locking hole 32. The knob 43 is easier to operate and saves labor by moving the knob 43 to open the locking hole 32.

[0061] Preferably, the shielding member 41 is rotationally connected to the base 213 to open or shield the locking hole 32; when the support 10 is in the unlocked state, the shielding member 41 prevents the second locking member from entering the locking hole 32. This further ensures the smooth progress of the miter saw 100 during processing.

[0062] Preferably, the base 213 further comprises an auxiliary handle 23. One end of the pull rod 22 cooperates with the output saw assembly 110 of the miter saw 100; the auxiliary handle 23 is arranged at the end of the pull rod 22 away from the output saw assembly 110; the auxiliary handle 23 is rotationally connected to the pull rod 22 around the first axis.

[0063] Further, in order to facilitate the adjustment of the sliding of the pull rod 22 relative to the base 213, it is common to fixedly arrange a handle on the pull rod 22. However, this brings the problem that the user can only hold the handle with a fixed grip to realize the pulling of the pull rod 22 relative to the base 213, which leads to the user's inability to adjust the position of the handle relative to the pull rod 22 to exert the pulling force on the handle according to the user's usage habit, thereby reducing the user's experience and the pulling efficiency.

[0064] Further, the handle is often vertically fixedly connected with the pull rod 22, that is, the two form an "L" shape. Therefore, when the user exerts the pulling force on the handle, the pulling force cannot be completely converted into the force to push the pull rod 22 to slide relative to the base 213, further reducing the adjustment efficiency.

[0065] In one specific example, in combination with the above-mentioned, the user can also hold the handle to achieve the carrying of the miter saw 100. There are various ways to carry the miter saw 100, specifically, the base 213, for example, includes the base 213, the rotating platform 211 and the extension table 212. The base 213 is provided with a mounting surface; the rotating platform 211 is rotatably connected to the mounting surface; the extension table 212 is provided on the mounting surface and is arranged adjacent to the rotating platform 211, and in addition, the extension table 212 is provided with a handle structure, and the user can hold the handle structure to achieve the carrying of the miter saw 100. Specifically, the number of extension tables 212 can be two, and the two extension tables 212 are arranged on both sides of the rotating platform 211, so that the two handle structures are held with both hands to achieve the effect of carrying the miter saw 100. However, the problem of carrying by this way is that due to the large size of the base 213, in combination with the distribution of parts of the miter saw 100, the heavy motor is arranged on the output saw assembly 110, and the pull rod 22 is connected to the base 213, so that the output saw assembly 110 is above the base 213. When the above-mentioned carrying method is used, the center of gravity of the miter saw 100 is high, and it is difficult to keep stable during carrying. In addition, the carrying method of holding two handle structures with both hands makes the user more tired during carrying, further reducing the efficiency of using this carrying method.

[0066] Therefore, the handle provided on the pull rod 22 can be held to achieve the carrying of the miter saw 100. However, similarly, the handle in the related art is fixedly connected with the pull rod 22, so that the user can only maintain a fixed lifting posture when carrying the miter saw 100, which reduces the user's experience, and in addition, the fixed connection between the handle and the pull rod 22 is easy to cause damage to the connection.

[0067] Therefore, in combination with the present technical solution, by rotatably connecting the auxiliary handle with the pull rod 22, the auxiliary handle 23 can be arranged in a linear manner with the pull rod 22 during the process of applying a pulling force to the pull rod 22 to adjust the sliding of the pull rod 22 relative to the base 213, so that the pulling force applied by the user can be completely converted into an effective pushing force to push the pull rod 22 to slide, thereby improving the adjustment efficiency. In addition, during the carrying of the entire miter saw 100, the inertia force generated by the rotation of the output saw assembly 110 relative to the pull rod 22 in the dynamic carrying environment can be reduced by the rotatable connection between the auxiliary handle 23 and the pull rod 22, that is, the auxiliary handle can be rotated relative to the pull rod 22 to offset part of the above-mentioned inertia force, so that the process of carrying the miter saw 100 is more comfortable.
