[0049] In order to thoroughly understand the present application, detailed steps and detailed structures will be presented in the following description to illustrate the technical solution of the present application. The preferred embodiments of the present application are described in detail below, but in addition to these detailed descriptions, the present application may also have other implementation methods.
[0050] like Figure 1 , Figure 2 As shown, this embodiment provides a miter saw, and its operating handle includes: a handle grip 2, a handle rotation shaft 21, and a rotation locking member 20. The handle rotation shaft 21 is configured to be connected to the cutting saw body 1 of the miter saw; the handle grip 2 is connected to the handle rotation shaft 21, and can rotate relative to the cutting saw body 1 under the action of the handle rotation shaft 21; the rotation locking member 20 is movably connected to the handle grip 2, and the rotation locking member 20 is partially exposed from the handle grip 2 for manual operation; the rotation locking member 20 can be partially engaged with or separated from the handle rotation limit block 23 of the cutting saw body 1 to limit the rotation of the handle grip 2 relative to the cutting saw body 1 or cancel the rotation restriction of the handle grip 2.
[0051] The cutting saw body 1 is the main part of the miter saw and also the part where the saw blade is located. The handle grip 2 is the part for the user to hold with the palm when using. The user can lift or lower the cutting saw body 1 of the miter saw by holding the handle grip 2 and pushing and pulling it to perform the cutting action on the product to be cut. The handle rotating shaft 21 is an axis for the handle grip 2 to be installed, and the handle grip 2 can rotate around it. The rotary locking member 20 is a locking structure that can be locked and unlocked. In this embodiment, when the rotary locking member 20 is locked, the handle grip 2 is restricted from rotating relative to the cutting saw body 1. When unlocked, the rotation restriction of the handle grip 2 is cancelled. For the user, after unlocking the rotary locking member 20, the handle grip 2 is rotated to the desired position, and then the rotary locking member 20 is locked to fix the handle grip 2 to the desired position.
[0052] like Figure 3 As shown, the operating handle of the miter saw provided in this embodiment, when the miter function is used, the handle working surface forms an angle θ with the horizontal plane when the handle grip portion 2 is not adjusted, and the user unlocks the handle grip portion 2 by rotating the locking member 20, and adjusts the handle grip portion 2 to the angle θ. Figure 4 The position shown is then locked by rotating the locking member 20. At this time, the handle action surface of the handle grip portion 2 is in a horizontal plane, and the user can grip the handle grip portion 2 more smoothly when naturally stretching out his hand, and the user experience is improved.
[0053] Through the above design, the miter saw operating handle and the miter saw provided in this embodiment, the handle grip portion 2 can be rotated to adjust the angle relative to the cutting saw body 1, and can be fixed at a selected angle, so that the user can adjust the handle grip portion 2 to a convenient position when using the miter function, and for left-handed users, the angle of the handle grip portion 2 can be adjusted to be located on the left hand side of the user, thereby improving the user's convenience and comfort.
[0054] In an optional embodiment, if Figure 5 As shown, the rotation locking member 20 includes: a button portion 201 and a limiting column 202, the button portion 201 is exposed on the handle grip portion 2; the limiting column 202 can be engaged with the limiting groove 231 on the handle rotation limiting block 23; when the button portion 201 is moved by external force, the limiting column 202 is driven to move.
[0055] This embodiment provides a structural design of a rotation locking member 20, the principle of which is to utilize the structure that the rotation locking member 20 is connected to the handle grip portion 2 and can partially fit into the limit groove 231 on the handle rotation limit block 23, so that the handle grip portion 2 cannot rotate under the restriction of the limit groove 231. By operating the button portion 201, the position of the limit column 202 can be changed, so that the limit column 202 is inserted into the limit groove 231 or disengaged from the limit groove 231. After the limit column 202 is disengaged from the limit groove 231, the handle grip portion 2 can rotate freely.
[0056] In an optional embodiment, if Figure 2 , Figure 5 As shown, the limiting column 202 is a tapered column, and the inner wall profile of the limiting groove 231 matches the limiting column 202. That is, the limiting column 202 adopts rounded or beveled edge processing, so that when the limiting column 202 is roughly aligned with the limiting groove 231, the slope of the rounded or beveled angle is used for guidance, so that the limiting column 202 gradually completes the alignment with the center of the limiting groove 231 during the process of being inserted into the limiting groove 231, which is conducive to the rapid and accurate locking of the handle grip 2 during the rotation process. It can be understood that in order to reduce the difficulty of the limiting column 202 being inserted into the limiting groove 231, the rounded or beveled angle of the limiting column 202 can be appropriately designed to be a relatively large slope.
[0057] In an optional embodiment, if Figure 2 As shown, the miter saw operating handle further includes a reset member 27, and the reset member 27 is connected to the rotation locking member 20. The rotation locking member 20 keeps the rotation restriction of the handle grip portion 2 under the action of the reset member 27. In this embodiment, by setting the reset member 27, when the user does not operate the rotation locking member 20, that is, when the rotation locking member 20 is not subjected to external force, the rotation locking member 20 is in a locked state, ensuring that the handle grip portion 2 is in a locked state, which is convenient for use.
[0058] In an optional embodiment, if Figure 2 , Figure 5 As shown, the miter saw operating handle further includes a reset member mounting seat 26, and the reset member mounting seat 26 is located inside the handle grip portion 2, and one end of the reset member 27 is fixed on the reset member mounting seat 26, and the other end abuts against the button portion 201. In this embodiment, the reset member 27 can be easily installed by setting the reset member mounting seat 26, so that the position of the reset member 27 is limited to a certain extent, so as to ensure that the other end of the reset member 27 abuts against the button portion 201, so that the rotation locking member 20 can be easily kept in a locked state.
[0059] In an optional embodiment, if Figure 2 , Figure 5As shown, the button portion 201 is cylindrical or conical, the handle grip portion 2 has a button movable hole, one end of the button portion 201 is exposed to the handle grip portion 2 through the button movable hole, and the other end of the button portion 201 is recessed to form a limit hole for the end of the reset member 27 to be inserted into. In this embodiment, the button portion 201 is designed as a cylindrical or conical thin shell structure, which uses less material, and the end is convenient for human hand pressing and is conducive to the insertion of the reset member 27.
[0060] In an optional embodiment, if Figure 2 As shown, the miter saw operating handle also includes a locking rotation shaft 24, the locking rotation shaft 24 is fixed to the handle grip 2, the rotation locking member 20 is connected to the locking rotation shaft 24, and when the rotation locking member 20 rotates around the locking rotation shaft 24, a part of the rotation locking member 20 can be engaged with or separated from the handle rotation limit block 23 of the cutting saw body 1. In this embodiment, the rotation locking member 20 is movable by rotating, the structure is simple, the range of motion is highly controllable, and a simple reset member 27 can be used to reset, such as a spring reset, and the solution is highly feasible and easy to industrialize.
[0061] In an optional embodiment, if Figure 2 As shown, the handle rotating shaft 21 is inserted into the stepped hole of the cutting saw body 1 and fixed by fasteners to ensure that the handle rotating shaft 21 will not rotate or fall off during the rotation of the handle grip 2. The handle grip 2 is connected to the handle rotating shaft 21 through a rotating sleeve 22 so as to rotate around it.
[0062] This embodiment provides a miter saw, such as Figure 1 , Figure 2 As shown, it includes the miter saw operating handle, as well as a cutting saw body 1, a rotating connection member 8 and a base 10. The cutting saw body 1 is connected to the base 10 through the rotating connection member 8, and the cutting saw body 1 can rotate relative to the base 10 around the axis of the rotating connection member 8; the axis of the rotating connection member 8 is parallel to the axis of the handle rotating shaft 21.
[0063] When the miter saw provided in this embodiment uses its miter function, the operator needs to rotate the cutting saw body 1 around the axis of the rotating connecting member 8 to make the cutting saw body 1 tilt relative to the horizontal plane, such as Figure 3 As shown, the base 10 is placed horizontally. When the cutting saw body 1 is tilted relative to the horizontal plane, the handle grip 2 forms an angle θ with the horizontal plane, which is not convenient to use. In order to make the handle grip 2 convenient to use, the operating handle adjustment function of the miter saw operating handle of this embodiment can be used to unlock the handle grip 2 by rotating the locking member 20, and adjust the handle grip 2 to the angle as shown in FIG. Figure 4The position shown is then locked by rotating the locking member 20. At this time, the handle action surface of the handle grip portion 2 is in a horizontal plane, and the user can grip the handle grip portion 2 more smoothly when naturally stretching out his hand, and the user experience is improved.
[0064] Through the above design, the miter saw provided in this embodiment can rotate the handle grip 2 to adjust the angle relative to the cutting saw body 1 and can be fixed at a selected angle, so that the user can adjust the handle grip 2 to a convenient position when using the miter function. For users with left-handed dominance, the angle of the handle grip 2 can be adjusted to be located on the user's left hand side, thereby improving user convenience and comfort.
[0065] In an optional embodiment, if Figure 1 As shown, the miter saw further includes an auxiliary handle 7, which is connected to the cutting saw body 1, and the auxiliary handle 7 and the handle gripping portion 2 are respectively located on opposite sides of the cutting saw body 1. In this embodiment, when the user moves the miter saw, the miter saw of this design is provided with an auxiliary handle 7 for grasping in addition to the operating handle, so that the user can move the miter saw more easily and balancedly.
[0066] In an optional embodiment, if Figure 1 , Figure 2 As shown, the auxiliary handle 7 is rotatably connected to the cutting saw body 1, and the auxiliary handle 7 can be at least in a hidden position or an exposed position when it is rotated. When the auxiliary handle 7 is in the hidden position, it is perpendicular to the axis of the handle rotating shaft 21, and when the auxiliary handle 7 is in the exposed position, it is parallel to the axis of the handle rotating shaft 21. In this embodiment, the auxiliary handle 7 is designed to be hidden, and can be rotated to the hidden position when not in use, so that it does not protrude from the whole miter saw, so as to avoid it occupying more space and affecting use.
[0067] It should be understood that the above embodiments are exemplary and are not intended to include all possible implementations included in the claims. Various modifications and changes may be made on the basis of the above embodiments without departing from the scope of the present disclosure. Similarly, the various technical features of the above embodiments may be arbitrarily combined to form other embodiments of the present application that may not be explicitly described. Therefore, the above embodiments only express several implementations of the present application and do not limit the scope of protection of the patent of this application.
