[0047] To thoroughly understand the present application, detailed steps and detailed structures will be presented in the following description to illustrate the technical solutions of the present application. The preferred embodiments of the present application are described in detail below. However, in addition to these detailed descriptions, the present application may also have other implementation manners.

[0048] This embodiment provides a miter saw, as Figure 1 shown, including: a base 6, a cutting body 1 and an operation handle 2. The base 6 is used to carry the object to be cut. The cutting body 1 is rotatably connected to the base 6. The cutting body 1 has a saw blade 7 for cutting. The operation handle 2 is fixed on the cutting body 1. Among them, the operation handle 2 is for the user to hold with the hand to perform the operations of pressing down and lifting up the cutting body 1. When the cutting body 1 is lifted to the highest point, the saw blade is located at a position away from the base 6. This position is the rest position of the cutting body 1. The rest position of the cutting body 1 is generally used for standby and for placing the object to be cut between the saw blade 7 and the base 6. On the contrary, when the cutting body 1 is pressed down to the lowest point, the saw blade 7 is located at a position close to the base 6. This position is the fully pressed-down position of the cutting body 1. The cutting body 1 pressing down from the rest position to the fully pressed-down position is used to cut the object.

[0049] Generally, a miter saw includes a base 6, a cutting body 1, an operating handle 2, and a saw blade 7. The saw blade 7 is installed on the cutting body 1 of the miter saw, and the cutting body 1 is rotatably connected to the base 6. The base 6 is used to carry the object to be cut. The cutting body 1 is rotatably connected to the base 6 and has a saw blade 7 for cutting. The operating handle 2 is fixed to the cutting body 1. Among them, the operating handle 2 is for the user to hold by hand to perform the operations of pressing down and lifting up the cutting body 1. When the cutting body 1 is lifted to the highest point, the saw blade 7 is located at a position away from the base 6, and this position is the rest position of the cutting body 1. The rest position of the cutting body 1 is generally used for standby and for placing the object to be cut between the saw blade 7 and the base 6; on the contrary, when the cutting body 1 is pressed down to the lowest point, the saw blade 7 is located at a position close to the base 6, and this position is the fully pressed-down position of the cutting body 1. The cutting body 1 is pressed down from the rest position to the fully pressed-down position for cutting the object.

[0050] This embodiment provides a miter saw, as Figure 1 、 Figure 2 shown, including: a saw blade 7, an operating handle 2, a switch group 300, and a status indicator light group 200.

[0051] The operating handle 2 includes a handle body 100 and a grip 101. The grip 101 is connected to the handle body 100 and is configured to be held by the user's hand. A mounting surface 400 is formed at the top of the handle body 100, and the height of the mounting surface 400 is equal to or higher than the top surface of the grip 101. At least a part of the mounting surface 400 is perpendicular to the plane where the saw blade 7 is located.

[0052] The switch group 300 is installed on the mounting surface 400 to control several functions of the miter saw; the status indicator light group 200 is installed on the mounting surface 400 to indicate the enabled status of several functions of the miter saw. The switch styles in the switch group 300 include, but are not limited to, buttons, knobs, rollers, pressure-sensitive elements, touch screens, etc. The enabled status of the functions includes, but is not limited to, states such as on, off, pause, fault, high speed, low speed, etc., and the indicating methods include, but are not limited to, lighting, extinguishing, flashing, partial lighting, lighting to form patterns, numbers, or words, etc.

[0053] The miter saw provided by the embodiment of the present application has an installation surface 400 formed at the top of the handle main body 100. The installation surface 400 is at least partially perpendicular to the plane where the saw blade 7 of the miter saw is located, so that it is easy for the user to clearly see the installation surface 400 from a perspective convenient for observing the cutting situation of the saw blade 7. The height where the installation surface 400 is located is equal to or higher than the top surface of the grip 101. In this layout, the grip 101 and the user's own arm when grasping the grip 101 are not likely to block the line of sight when the user observes the installation surface 400. Therefore, the status indicator light group 200 and the switch group 300 are arranged on the installation surface 400. When the user operates the miter saw, the switch and the corresponding status indicator light can be clearly seen in the field of vision at the same time, which is convenient for operation. Moreover, whether the cutting main body 1 is in the rest position or the fully depressed position, the switch group and the status indicator light group can be within the user's field of vision, which is convenient for the user to view and improves the user experience.

[0054] In an alternative embodiment, as Figure 1 shown, both the installation surface 400 and the top surface of the grip 101 are located above the saw blade 7. In this embodiment, the installation surface 400 and the top surface of the grip 101 are arranged at a position higher than the saw blade 7 and are at the top of the entire miter saw. Generally, the user's line of sight when observing the saw blade 7 is obliquely downward. Therefore, it is easier for the user to observe when it is at the top of the entire miter saw.

[0055] In an alternative embodiment, as Figure 2 shown, the installation surface 400 extends in a first direction, and the grip 101 extends in a second direction. The second direction is perpendicular to the first direction, and the second direction is perpendicular to the plane where the saw blade 7 is located. In this embodiment, the handle main body 100 and the grip 101 of the operating handle 2 extend in two directions respectively, and do not interfere with each other in terms of space occupation. And because the second direction is perpendicular to the first direction, when the user's hand holds the grip 101, from the perspective of the field of vision of the eyes, neither the arm nor the palm will block the installation surface 400.

[0056] In an alternative embodiment, as Figure 2As shown, the first direction is the front - rear direction of the miter saw, and the second direction is the left - right direction of the miter saw. The handle 101 includes: a first grip portion 1011 extending along the left - right direction, and a second grip portion 1012 extending along the front - rear direction. The first grip portion 1011 is in front of the mounting surface 400, and the second grip portion 1012 is on the left or right side of the plane where the saw blade 7 is located. In this embodiment, the first grip portion 1011 is in front of the miter saw, near the position where the user is usually located, facilitating the user's grip. The second grip portion 1012 is on the left or right side of the plane where the saw blade 7 is located, at the possible position of the user, facilitating the user's grip when using the miter saw on the left or right side.

[0057] In an alternative embodiment, as Figure 2 shown, the switch group 300 includes a number of switches, and the status indicator group 200 includes a number of status indicators. The number of switches and status indicators are arranged along the first direction. In this embodiment, the direction in which the number of switches and status indicators are arranged is consistent with the extending direction of the mounting surface 400, which can make full use of the area of the mounting surface 400, enabling the switches and status indicators to be arranged in an orderly manner and not easily causing visual occlusion with each other.

[0058] In an alternative embodiment, as Figure 2 shown, the switch group 300 includes: a speed - regulating knob 3, a laser switch 4, and an LED switch 5. The speed - regulating knob 3 is electrically connected to the saw - blade drive motor to adjust the speed gear of the saw - blade drive motor. The laser switch 4 is electrically connected to the laser lamp of the miter saw to adjust the display or turn - off of the laser - indicating line of the laser lamp. The LED switch 5 is electrically connected to the lighting lamp of the miter saw to adjust the turning - on or turning - off of the lighting lamp. Herein, the saw - blade drive motor refers to the motor used to drive the saw blade to rotate, and the laser lamp is a lamp that emits laser light, which functions to project an indicating line on the surface of the object to be cut. Generally, operators use this indicating line to determine whether the position to be cut is accurate. The lighting lamp is used for lighting in a dark working environment. In this embodiment, arranging the speed - regulating knob 3, the laser switch 4, and the LED switch 5 within the range of the mounting surface 400 facilitates the user to start or turn off the above three functions.

[0059] In an alternative embodiment, as Figure 2As shown, along the first direction, the speed control knob 3 is separately arranged, and the laser switch 4 and the LED switch 5 are arranged side by side. Pointer 31 is provided on both sides of the speed control knob 3, and the pointer 31 is used to point to the corresponding mark on the speed control knob 3 to indicate the gear at which the speed control knob 3 is adjusted. In this embodiment, since the speed control knob 3 needs to occupy a relatively large area and is separately arranged, while the laser switch 4 and the LED switch 5 occupy a relatively small area and are arranged side by side to make full use of the area of the mounting surface 400.

[0060] In an alternative embodiment, as Figure 3 shown, the status indicator light group 200 includes: a gear indicator light 211, a laser indicator light 212, and an LED indicator light 214; the gear indicator light 211 is electrically connected to the speed control knob 3 to display the rotation speed gear of the saw blade drive motor, the laser indicator light 212 is electrically connected to the laser switch 4 to indicate the display state of the laser indication line, and the LED indicator light 214 is electrically connected to the LED switch 5 to indicate the on / off state of the lighting lamp. In this embodiment, by arranging the gear indicator light 211, the laser indicator light 212, and the LED indicator light 214 within the range of the mounting surface 400, it is convenient for the user to know the rotation speed gear, whether the laser indication line is displayed, or whether the lighting lamp is on.

[0061] In an alternative embodiment, as Figure 3 shown, the status indicator light group 200 further includes: a saw blade status light 213, and the saw blade status light 213 is used to indicate the operating state of the saw blade 7. In this embodiment, through the saw blade status light 213, it is convenient for the user to know the operating state of the saw blade, including normal rotation, stop, or abnormality, etc.

[0062] It can be understood that the gear indicator light 211, the laser indicator light 212, the saw blade status light 213, and the LED indicator light 214 are independent of each other and do not affect each other. Therefore, the status indicator light group 200 may include one or more of the above indicator lights.

[0063] In an alternative embodiment, as Figure 3 shown, along the first direction, the gear indicator light 211 is separately arranged, and the laser indicator light 212, the saw blade status light 213, and the LED indicator light 214 are arranged side by side. In this embodiment, since the gear indicator light 211 needs to indicate multiple gears, the arrangement of the lamp beads is relatively complex and the occupied area is relatively large, so it is separately arranged. While the laser indicator light 212, the saw blade status light 213, and the LED indicator light 214 need to indicate relatively less content, so the occupied area is relatively small and they can be arranged side by side. This arrangement makes full use of the area of the mounting surface 400.

[0064] In an alternative embodiment, as Figure 1 、 Figure 2As shown, the operating handle further includes: a start button 19, which is electrically connected to the saw blade drive and the saw blade status light 213, and is used to control the start or stop of the saw blade drive. When the saw blade drive starts or stops, the saw blade status light 213 can give corresponding indications. The start button 19 can be arranged at the rear side of the first grip part 1011, which conforms to the position where the fingers are located when the human hand holds the first grip part 1011, so as to facilitate blind operation.

[0065] In an alternative embodiment, as Figure 4 shown, in the first direction, the height difference between the points on the mounting surface 400 and the top surface of the grip 101 gradually increases in the direction away from the grip 101. In this embodiment, the mounting surface 400 forms a certain slope relative to other parts of the handle body 100. As Figure 4 shown, the farther away from the grip 101, the higher the height of the mounting surface 400. And the user is located on the side of the operating handle 2 where the grip 101 is provided. The farther away from the grip 101, the less visible it is. Therefore, this slope design of the mounting surface 400 can alleviate the problem that the user cannot clearly see the status indicator lights at a farther distance.

[0066] In an alternative embodiment, as Figure 2 shown, in the first direction, a switch group 300 and a status indicator light group 200 are arranged in sequence in the direction away from the grip 101. Such an arrangement preferentially sets the switch at a position close to the grip 101 so that the user can operate the switch with the hand, while the status indicator lights only for viewing are set at a relatively farther position, making reasonable use of the space of the mounting surface 400.

[0067] In an alternative embodiment, as Figures 1-4 shown, the mounting surface 400 is a single plane. Under this design scheme, the orientation of the mounting surface 400 is single, and it is easy to arrange various switches or status indicator lights thereon. It can be understood that in other embodiments, the mounting surface 400 can also be a single arc surface, a combination of several planes, a combination of several arc surfaces, or a combination of several planes and arc surfaces.

[0068] It should be understood that the above embodiments are all exemplary and do not cover all possible implementation manners included in the claims. Without departing from the scope of the present disclosure, various deformations and changes can also be made on the basis of the above embodiments. Similarly, various technical features of the above embodiments can also be arbitrarily combined to form other embodiments of the present application that may not be clearly described. Therefore, the above embodiments only represent several implementation manners of the present application and do not limit the protection scope of the patent of the present application.
