Description

Technical Field

[0001] The invention discloses an electric tool with an adjustable handle, belonging to the technical field of electric tools. Background Art

[0002] An electric circular saw is a commonly used electric cutting tool. A DC electric circular saw is particularly popular with users and is more widely used because it is not restricted by the workplace. An electric circular saw usually uses a drive motor to drive the circular saw blade to rotate, thereby performing cutting.

[0003] The casing of an electric circular saw is usually provided with a handle for the user to hold, but in existing electric circular saws, the handle and the casing are usually an integrated structure. When the electric circular saw is in use, the user needs to bend his arm in order to apply external force to better control the electric circular saw. When the electric circular saw is used against a wall, the distance between the handle and the wall is small, which may cause the arm to hit the wall, affecting the position adjustment of the arm, making it difficult for the user to apply force, thereby increasing the difficulty of the electric circular saw cutting operation against the wall. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that the existing electric circular saw is difficult to cut against a wall. To this end, an electric tool with an adjustable handle is provided. By rotating the handle, the distance between the handle and the wall can be increased to reduce the difficulty of the electric circular saw cutting against the wall.

[0005] To solve the above technical problems, the present invention adopts the following technical solutions:

[0006] An electric tool with an adjustable handle comprises a casing and a handle rotatably connected to the casing, the casing is provided with a circular saw blade and a driver for driving the circular saw blade, a positioning groove is provided at the connection between the casing and the handle, a positioning lock cooperating with the positioning groove is provided in the handle, the positioning groove comprises a first groove for positioning the handle in a first position and a second groove for positioning the handle in a second position, a first reset member is provided in the handle, the first reset member enables the positioning lock to have a movement tendency to be positioned in the first groove or the second groove, the positioning lock has an operating part extending out of the surface of the handle, the operating part drives the positioning lock to switch between the first groove and the second groove, when the handle is in the first position, the plane where the handle is located remains parallel to the circular saw blade, and when the handle is in the second position, the handle is tilted toward the side away from the circular saw blade.

[0007] The beneficial effects of adopting the present invention are:

[0008] The handle described in the present invention is rotatably connected to the casing, and a positioning lock and a positioning groove are provided at the connection between the handle and the casing. The positioning groove includes a first groove and a second groove. When the positioning lock is located in the first groove, the handle is located in the first position. At this time, the end of the handle is perpendicular to the connecting surface of the casing, and the handle and the circular saw blade remain parallel. When the positioning lock is located in the second groove, the handle is located in the second position. At this time, the handle is tilted toward the side away from the circular saw blade, thereby increasing the distance between the top of the handle and the circular saw blade. When the electric tool is used for wall cutting, the handle is positioned in the second position, which can increase the distance between the handle and the wall, providing a larger space for the user's handle, thereby reducing the risk of the electric tool being used for wall cutting. The first reset member enables the positioning lock to have a movement tendency to be positioned in the first groove or the second groove, thereby simplifying the adjustment process of the positioning lock. The user only needs to apply external force to the positioning lock when switching the position of the positioning lock. At the same time, the first reset member can also limit the positioning lock from being arbitrarily separated from the positioning groove, which helps to improve the matching stability between the positioning lock and the positioning groove, reduce the possibility of the positioning lock being arbitrarily separated from the positioning groove, make the positioning of the handle more firm and reliable, and help to improve the safety of the use of the power tool; secondly, when the handle is in the second position, the overall height of the power tool can be reduced, thereby reducing the required packaging size of the power tool, which helps to reduce the packaging and transportation costs of the power tool.

[0009] Preferably, a partition is provided between the first groove and the second groove, and the operating part drives the positioning lock to cross the partition to switch the positioning lock between the first groove and the second groove. With the above technical solution, the presence of the partition provides a clear boundary for the positioning lock, ensuring that when the positioning lock is located in the first groove or the second groove, it can be firmly maintained in the corresponding position, reducing the possibility of the positioning lock switching between the first groove and the second groove at will.

[0010] Preferably, the first groove and the second groove are distributed along the axial direction of the positioning lock and staggered in the axial direction. A second reset member is provided in the handle, and the second reset member acts on the end of the positioning lock away from the operating part, pressing the operating part to drive the positioning lock to move along the axial direction.

[0011] Preferably, the end of the positioning lock away from the operating portion is provided with a second limiting groove for the second reset member to extend into. With the above technical solution, the second reset member forms a stable connection with the positioning lock by extending into the second limiting groove, which helps to improve the matching stability of the second reset member and the positioning lock, and also reduces the possibility of the second reset member being separated from the abutment column; in addition, the second reset member acts on the positioning lock, which can make the positioning lock always exposed to the handle, avoiding the possibility of the positioning lock being completely sunk into the handle, making the assembly of the positioning lock and the handle more stable and reliable.

[0012] Preferably, a positioning column is provided on the side of the positioning lock facing the positioning groove, and the positioning column is inserted into the first groove or the second groove to position the positioning lock and the positioning groove. With the above technical solution, the tight fit between the positioning column and the first groove or the second groove ensures the positioning stability of the positioning lock, and can also reduce the possibility of the positioning lock accidentally moving or loosening due to external vibration, impact or improper operation. At the same time, when the positioning column is inserted into the positioning groove, the positioning lock and the positioning groove form a stable and reliable positioning through the positioning column, thereby improving the connection stability and reliability of the handle and the housing.

[0013] Preferably, the positioning lock is provided with an abutment column on one side away from the positioning groove, and the end of the abutment column is provided with a first limiting groove for the first reset member to extend into. With the above technical solution, the first reset member forms a stable connection with the abutment column by extending into the first limiting groove, which helps to improve the matching stability between the first reset member and the abutment column, and also reduces the possibility of the first reset member being separated from the abutment column; in addition, after the first reset member extends into the first limiting groove, it can provide stable support and guidance for the positioning lock.

[0014] Preferably, a slide groove is provided in the handle, and the abutment column is restricted in the slide groove. With the above technical solution, the slide groove can provide a stable moving path for the abutment column, so that the positioning lock can move more smoothly along the length direction of the abutment column, reducing the possibility of the abutment column being offset or stuck; in addition, the slide groove can also limit the abutment column, ensuring that the positioning lock can be aligned with the positioning groove, thereby improving the positioning accuracy of the positioning lock and the positioning groove.

[0015] Preferably, the housing is provided with a boss extending toward the handle, a positioning groove is formed on the top surface of the boss, two connecting plates are provided at the end of the handle, the boss is embedded between the two connecting plates, and shaft holes are provided on the boss and the connecting plate, and the handle and the housing are rotatably connected by the cooperation of a rotating pin and the shaft hole. With the aforementioned technical solution, the design of the boss and the connecting plate makes the assembly process of the handle and the housing simpler and more intuitive. The user only needs to insert the boss between the two connecting plates and achieve connection by the cooperation of the rotating pin and the shaft hole. When the handle needs to be maintained or replaced, the user can easily separate the handle from the housing by disassembling the rotating pin, thereby simplifying the maintenance process and reducing costs.

[0016] Preferably, the end of the handle is provided with an escape notch for the handle to rotate. With the above technical solution, the escape notch can provide an escape space for the handle to rotate, thereby preventing the handle from abutting against the housing and limiting the normal rotation of the handle.

[0017] Preferably, the operating part is threadedly connected to the positioning lock, and the diameter of the operating part is larger than the diameter of the positioning lock. With the above technical solution, the operating part has a larger diameter, so that the user can more easily hold and apply sufficient force to control the positioning lock when using it, which helps to improve the switching efficiency of the handle and also makes the switching of the handle simpler and more convenient.

[0032] Embodiment 1:

[0033] like Figures 1 to 7As shown, this embodiment shows an electric tool with an adjustable handle 2, including a housing 1 and a handle 2 rotatably connected to the housing 1, the housing 1 is provided with a circular saw blade 4 and a driver for driving the circular saw blade 4, the handle 2 is C-shaped as a whole, both ends of the handle 2 are hinged to the upper surface of the housing 1, a positioning groove 12 is provided at the connection between the housing 1 and the handle 2, a positioning lock 3 cooperating with the positioning groove 12 is provided in the handle 2, the positioning groove 12 includes a first groove 121 for positioning the handle 2 at a first position and a second groove 122 for positioning the handle 2 at a second position, a first reset member 322 is provided in the handle 2, the first reset member 322 enables the positioning lock 3 to have a movement tendency to be positioned in the first groove 121 or the second groove 122, the positioning lock 3 has an operating portion 31 extending from the surface of the handle 2, the operating portion 31 drives the positioning lock 3 to switch between the first groove 121 and the second groove 122, when the handle 2 is in the first position, the plane where the handle 2 is located remains parallel to the circular saw blade 4, and when the handle 2 is in the second position, the handle 2 is tilted toward the side away from the circular saw blade 4.

[0034] In the present embodiment, the handle 2 is rotatably connected to the casing 1, and a positioning lock 3 and a positioning groove 12 are provided at the connection between the handle 2 and the casing 1. The positioning groove 12 includes a first groove 121 and a second groove 122. When the positioning lock 3 is positioned in the first groove 121, the handle 2 is positioned in the first position. At this time, the end of the handle 2 is perpendicular to the connecting surface of the casing 1, and the handle 2 and the circular saw blade 4 remain parallel. When the positioning lock 3 is positioned in the second groove 122, the handle 2 is positioned in the second position. At this time, the handle 2 is tilted toward the side away from the circular saw blade 4, thereby increasing the distance between the top of the handle 2 and the circular saw blade 4. When the electric tool is used for cutting against a wall, positioning the handle 2 in the second position can increase the distance between the handle 2 and the wall, thereby providing a larger space for the user's handle 2, thereby reducing the distance between the electric tool and the wall. The difficulty of cutting operation is reduced, which provides convenience for users; the first reset member 322 enables the positioning lock 3 to have a movement tendency to be positioned in the first groove 121 or the second groove 122, thereby simplifying the adjustment process of the positioning lock 3. The user only needs to apply external force to the positioning lock 3 when switching the position of the positioning lock 3. At the same time, the first reset member 322 can also limit the positioning lock 3 from arbitrarily disengaging from the positioning groove 12, which helps to improve the matching stability of the positioning lock 3 and the positioning groove 12, and reduce the possibility of the positioning lock 3 arbitrarily disengaging from the positioning groove 12, so that the positioning of the handle 2 is more firm and reliable, which helps to improve the safety of the use of the power tool; secondly, when the handle 2 is in the second position, the overall height of the power tool can be reduced, thereby reducing the packaging size required for the power tool, which helps to reduce the packaging and transportation costs of the power tool.

[0035] like Figures 3 to 5As shown, in this embodiment, the upper surface of the housing 1 and the connection between the housing 1 and the handle 2 are provided with a boss 11 extending toward the handle 2, and two connecting plates 21 are provided at the end of the handle 2. When the handle 2 and the housing 1 are assembled, the boss 11 is embedded between the two connecting plates 21, and the boss 11 and the connecting plate 21 are both provided with an axis hole 13. The handle 2 and the housing 1 are rotatably connected by cooperating with the axis hole 13 through the rotating pin 5, and the handle 2 rotates around the rotating pin 5; in addition, as shown in FIG. Figure 1 and Figure 2 As shown, in order to ensure that the rotation of the handle 2 is not hindered, an avoidance gap 25 is provided between the end of the handle 2 and the casing 1 in this embodiment. When the handle 2 is in the first position, the avoidance gap 25 is located on the side of the handle 2 away from the circular saw blade 4, so that the handle 2 can be rotated toward the side away from the circular saw blade 4, so that the handle 2 can be rotated to the second position; and when the handle 2 is in the second position, the avoidance gap 25 is located on the side of the handle 2 close to the circular saw blade 4, so that the handle 2 can be rotated toward the side close to the circular saw blade 4, so that the handle 2 can be rotated back to the first position. During the assembly process of the handle 2 and the boss 11, the design of the boss 11 and the connecting plate 21 makes the assembly process of the handle 2 and the casing 1 simpler and more intuitive. The user only needs to insert the boss 11 between the two connecting plates 21 and achieve the connection by cooperating with the rotating pin 5 and the shaft hole 13. When the handle 2 needs to be maintained or replaced, the user can easily separate the handle 2 from the casing 1 by disassembling the rotating pin 5, thereby simplifying the maintenance process and reducing costs.

[0036] like Figures 3 to 5 As shown, the positioning lock 3 described in this embodiment is installed inside the handle 2, and the positioning groove 12 is set on the upper surface of the boss 11. When the handle 2 is assembled with the housing 1, the handle 2 covers the boss 11, and the positioning lock 3 is on the upper side of the boss 11. The front side of the handle 2 is provided with a through hole, and the end of the positioning lock 3 passes through the through hole and is exposed on the surface of the handle 2. A positioning column 33 is provided on the side of the positioning lock 3 facing the positioning groove 12, and an abutment column 32 is provided on the side of the positioning lock 3 facing away from the positioning groove 12. A first abutment plate 22 is provided in the handle 2, and a first reset member 322 is installed on the first abutment plate 22. One end of the first reset member 322 abuts against the first abutment plate 22, and the other end of the first reset member 322 abuts against the first abutment plate 22. One end abuts against the abutment column 32, and the first reset member 322 acts on the abutment column 32, so that the positioning lock 3 as a whole has a movement tendency to move toward the positioning groove 12. In addition, the end of the abutment column 32 is provided with a first limiting groove 321 for the first reset member 322 to extend into. The first reset member 322 forms a stable connection with the abutment column 32 by extending into the first limiting groove 321, which helps to improve the matching stability of the first reset member 322 and the abutment column 32, and at the same time can also reduce the possibility of the first reset member 322 detaching from the abutment column 32; in addition, after extending into the first limiting groove 321, the first reset member 322 can provide stable support and guiding effect for the positioning lock 3.

[0037] like Figure 6 and Figure 7 As shown, in this embodiment, a slide groove 24 is provided on the lower side of the first abutment plate 22, and the slide groove 24 is formed between the two limit plates. The abutment column 32 is in the slide groove 24, and the slide groove 24 can provide a stable moving path for the abutment column 32, so that the movement of the positioning lock 3 along the length direction of the abutment column 32 is smoother and smoother, and the possibility of the abutment column 32 being offset or stuck is reduced; in addition, the slide groove 24 can also limit the abutment column 32, ensuring that the positioning lock 3 can remain aligned with the positioning groove 12, thereby improving the positioning accuracy of the positioning lock 3 and the positioning groove 12.

[0038] like Figure 4 and Figure 5 As shown, in this embodiment, a partition 123 is provided in the positioning groove 12, and the partition 123 divides the positioning groove 12 into the first groove 121 and the second groove 122. The first groove 121 and the second groove 122 are distributed along the axial direction of the positioning lock 3, and the first groove 121 and the second groove 122 are staggered in the axial direction. In addition, a second abutment plate 23 is provided in the handle 2, and a second reset member 34 is installed on the second abutment plate 23. One end of the second reset member 34 abuts against the second abutment plate 23, and the other end abuts against the end of the positioning lock 3 away from the operating portion 31. A second limiting groove for the second reset member 34 to extend into is provided at the end of the positioning lock 3 away from the operating portion 31. The second reset member 34 forms a stable connection with the positioning lock 3 by extending into the second limiting groove, which helps to improve the matching stability of the second reset member 34 and the positioning lock 3, and also reduces the possibility of the second reset member 34 detaching from the abutment column 32; in addition, the second reset member 34 acts on the positioning lock 3, which can make the positioning lock 3 always exposed to the handle 2, avoiding the possibility of the positioning lock 3 being completely sunken into the handle 2, and making the assembly of the positioning lock 3 and the handle 2 more stable and reliable.

[0039] like Figure 3 As shown, the operating part 31 described in this embodiment is threadedly connected with the positioning lock 3, and the end of the positioning lock 3 exposed from the handle 2 is provided with a threaded hole, and the operating part 31 is provided with a threaded column threadedly matched with the threaded hole. When the operating part 31 and the positioning lock 3 are installed, the threaded column of the operating part 31 extends into the threaded hole and is threadedly connected with the threaded hole. In addition, the diameter of the operating part 31 is larger than the diameter of the positioning lock 3. The larger diameter of the operating part 31 makes it easier for the user to hold and apply enough force to control the positioning lock 3 when in use, which helps to improve the switching efficiency of the handle 2 and also makes the switching of the handle 2 simpler and more convenient.

[0040] like Figure 6 and Figure 7 As shown, the position switching of the handle 2 between the first position and the second position in this embodiment is as follows: Figure 6As shown, at this time, the handle 2 is in the first position, and the handle 2 as a whole remains parallel to the circular saw blade 4, so that the normal operation of the power tool can be realized. In addition, when the handle 2 is in the first position, the positioning column 33 of the positioning lock 3 is embedded in the first groove 121, and the inner wall of the first groove 121 forms a circumferential and axial limit for the positioning column 33, thereby reducing the shaking amplitude of the positioning column 33, so that the handle 2 has a more reliable positioning stability when it is in the first position, and the possibility of the handle 2 shaking is reduced; in addition, the first reset member 322 acts on the abutment column 32 and forms an axial limit for the positioning column 33, reducing the possibility of the positioning column 33 arbitrarily detaching from the first groove 121, ensuring that the positioning column 33 can be firmly maintained in the first groove 121, reducing the possibility of the positioning lock 3 arbitrarily switching between the first groove 121 and the second groove 122; at the same time, the positioning lock 3 squeezes the second reset member 34, and the length of the positioning lock 3 exposed from the handle 2 is shorter.

[0041] like Figure 7 As shown, at this time, the handle 2 is in the second position, and the handle 2 is tilted toward the side away from the circular saw blade 4 as a whole, which can reduce the difficulty of the electric tool cutting against the wall. In addition, when the handle 2 is in the second position, the positioning column 33 of the positioning lock 3 is embedded in the second groove 122, and the inner wall of the second groove 122 forms a circumferential and axial limit for the positioning column 33, thereby reducing the shaking amplitude of the positioning column 33, so that the handle 2 has a more reliable positioning stability when it is in the second position, and reduces the possibility of the handle 2 shaking; in addition, the first reset member 322 acts on the abutment column 32 and forms an axial limit for the positioning column 33, reducing the possibility of the positioning column 33 arbitrarily detaching from the second groove 122, ensuring that the positioning column 33 can be firmly maintained in the second groove 122, and reducing the possibility of the positioning lock 3 switching between the first groove 121 and the second groove 122 at will; at the same time, because the second groove 122 is closer to the front end of the handle 2 than the first groove 121, and the length of the second reset member 34 is longer than the length when the handle 2 is in the first position, the length of the positioning lock 3 exposed from the handle 2 is longer.

[0042] When the handle 2 is in contact with the casing 1, the user releases the positioning lock 3, and the elastic forces of the first and second positioning members 322 and 34 are both released. The second positioning member 34 acts on the positioning lock 3 to move the positioning lock 3 in the axial direction. When the abutting column 32 abuts against the limiting plate of the slide groove 24, the positioning column 33 is aligned with the second groove 122, and the first positioning member 322 acts on the abutting end to make the positioning column 33 extend into the second groove 122, so that the positioning column 33 is positioned in the second groove 122, thereby positioning the handle 2 in the second position.

[0043] The first reset member 322 acts on the abutting end to make the positioning lock 3 move downward, so that the positioning column 33 extends into the first groove 121, and the positioning column 33 is positioned in the first groove 121, so that the handle 2 is positioned in the first position, that is, the handle 2 is parallel to the circular saw blade 4.

[0044] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes but is not limited to the contents described in the drawings and the above specific embodiments.
