[0055] Electric circular saw is a tool that uses a single-phase series motor as power to drive a circular saw blade through a transmission mechanism for sawing operations. It has the characteristics of safety, reliability, reasonable structure, and high working efficiency. It is suitable for sawing wood, fiberboard, plastic, soft cable and similar materials.

[0056] At present, in the actual processing process, electric circular saws are often required to perform slope cutting and depth cutting, so it is necessary to adjust the depth and deflection angle between the saw blade and the bottom plate 6. Since the angle and depth adjustment requirements of electric circular saws are relatively low in most cases, most electric circular saws can only be used for rough processing and cannot meet the use requirements of professional processing. In contrast, the guide rail 5 saw has higher processing accuracy and can meet certain precision processing, but the price of the guide rail 5 saw is much higher than that of ordinary electric circular saws. Therefore, under the premise of ensuring the cost, improving the processing accuracy of electric circular saws has received more and more attention.

[0057] In order to solve the above problems, the present application relates to an electric circular saw including a guide rail 5, a base plate 6 and a body. The guide rail 5 has a first track 51 and a second track 52 arranged at intervals along a first direction. The first track 51 and the second track 52 are both extended along a second direction, and the second direction is perpendicular to the first direction. The base plate 6 is movably arranged on the guide rail 5, and the base plate 6 is provided with a sliding part 61, and the sliding part 61 is adapted to the first track 51 and the second track 52. The body is movably arranged on the base plate 6, and the body has a first working state and a second working state. In the first working state, the saw blade of the body is perpendicular to the base plate 6, and the sliding part 61 is adapted to the first track 51. In the second working state, the angle between the saw blade and the base plate 6 is 45°, and the sliding part 61 is adapted to the second track 52.

[0058] The electric circular saw described in the utility model is used in conjunction with a guide rail 5 and a base plate 6, and a first track 51 and a second track 52 are provided on the guide rail 5, so as to meet 90° cutting and 45° cutting. This not only prevents users from using the wrong track due to unclearness and reduces risks, but also helps to improve the stability of the electric circular saw during cutting and the precise cutting in the second direction without increasing the processing cost of the electric circular saw too much.

[0059] Specifically, if Figure 1-3 As shown, the guide rail 5 has a first track 51 and a second track 52 arranged at intervals along a first direction a, and the first track 51 and the second track 52 are both extended along a second direction b, and the second direction b is perpendicular to the first direction a. In this embodiment, the guide rail 5 is arranged in a rectangular structure as a whole, and at this time, the first direction a is the length direction of the guide rail 5, and the second direction b is the width direction of the guide rail 5. It can be achieved that 90° cutting and 45° cutting have their own channels, and at the same time, as a fool-proof design, it helps to avoid users from misusing the tracks and reduce risks. Preferably, the first track 51 and the second track 52 are convexly arranged on the bottom plate 6 along a third direction c, and the third direction c is perpendicular to the first direction a and the second direction b, that is, the third direction c is the height direction, which helps to reduce the processing difficulty of the guide rail 5 and improve the production efficiency of the electric circular saw.

[0060] At this time, the number of guide rails 5 is at least four, and at least four guide rails 5 are spliced ​​and arranged along the second direction b. By providing at least four guide rails 5 that can be spliced ​​together, it is helpful to improve the length of accurate cutting, thereby helping to improve the flexibility of the use of the electric circular saw and meet the requirements of different environmental uses. Preferably, the length of the guide rail 5 is greater than or equal to 340m. Such an arrangement can make the spliced ​​guide rails 5 at least greater than 1.2m, which is convenient for carrying the electric circular saw. In this embodiment,

[0061] like Figure 1-Figure 3 As shown, the electric circular saw further includes a connecting rod 91 and a screw member 92, and at the same time, a plurality of mounting holes are provided on the side of the guide rail 5 away from the bottom plate 6. Since the first rail 51 and the second rail 52 are protrudingly provided on the bottom plate 6, a receiving groove is formed on the side of the first rail 51 and the second rail 52 away from the bottom plate 6. Preferably, a plurality of mounting holes are distributed at intervals on the first rail 51 and the second rail 52, and at this time, the receiving groove can accommodate the connecting rod 91. In this embodiment, a connecting hole is provided on the connecting rod 91, and the screw member 92 can pass through the connecting hole and be fixed in the mounting hole, thereby realizing the splicing between two adjacent guide rails 5, which not only makes the assembly of the guide rail 5 simple, but also has strong flexibility in use, and can effectively ensure the stability of the guide rail 5.

[0062] In some embodiments of the present application, the cross section of the sliding portion 61 is set to be a rectangle, wherein the cross section is perpendicular to the second direction b. Since the first track 51 and the second track 52 are protrudingly arranged on the guide rail 5, the sliding portion 61 on the bottom plate 6 is correspondingly set to be a groove 53, and the groove 53 is made by stamping. The groove 53 is adapted to the first sliding track and the second sliding track, has a simple structure, is easy to install, and helps to reduce the manufacturing and processing costs. Figure 3 As shown, the cross section of the groove 53 is a rectangle, that is, the sliding portion 61 is formed in an inwardly concave manner, which helps to further reduce the difficulty of processing the bottom plate 6, thereby helping to improve the processing and use effect of the electric circular saw. Figure 4 and Figure 5 As shown, when the above structure is used to realize the cooperation between the groove 53 and the first track 51 and the cooperation between the groove 53 and the second track 52, due to the effect of the electric circular saw's own gravity, the connection between the base plate 6 and the guide rail 5 is relatively stable, and it is not easy for the electric circular saw to deviate when moving in the length direction.

[0063] In this embodiment, the body includes a housing 1, a motor 2, a handle 3 and a saw blade 4. The housing 1 is used to be fixedly connected to the bottom plate, and the housing 1 is rotatably connected to the bottom plate 6. The saw blade 4 is arranged inside the housing 1, and the saw blade 4 can pass through the bottom plate 6 as the housing 1 rotates. Along the first direction a, the motor 2 is arranged on one side of the housing 1, and the handle 3 is arranged on the housing 1. The user can adjust the rotation angle of the housing 1, that is, the insertion depth of the saw blade 4, by holding the handle 3.

[0064] In some embodiments of the present application, the electric circular saw further includes an angle adjustment mechanism 7 and a depth adjustment mechanism 8. The angle adjustment mechanism 7 is disposed on the bottom plate 6, and the angle adjustment mechanism 7 is used to adjust the angle between the saw blade and the bottom plate 6. Figure 1 and Figure 6 As shown, the angle adjustment mechanism 7 is arranged on the bottom plate 6 and is arranged at one end of the bottom plate 6 along the length direction. Specifically, the angle adjustment mechanism 7 includes a fixing plate 71, a connecting member 72 and a first locking member 73. Among them, the fixing plate 71 is arranged on the bottom plate 6, the connecting member 72 is rotatably connected to the bottom plate 6, and the first locking member 73 is used to adjust the rotation angle of the connecting member 72.

[0065] Specifically, the fixing plate 71 is detachably disposed on the bottom plate 6, or is integrally formed on the fixing plate 71. Preferably, the fixing plate 71 and the bottom plate 6 are integrally formed. Figure 7 As shown, in this embodiment, an arc structure is provided on the fixing plate 71, and a fixing hole 712 and a positioning hole 711 are provided at one end of the arc structure away from the base plate 6, so as to be used in conjunction with the first arc groove 721 and the limiting hole 723 described below, so as to achieve the adjustment of the cutting angle of the electric circular saw.

[0066] At this time, the bottom plate 6 is also provided with a second pin hole 63. Figure 6 As shown, the connecting member 72 is set in a plate shape, and a first pin hole 724 is opened at the first end of the connecting member 72. By setting a rotating shaft passing through the first pin hole 724 and the second pin hole 63, the connecting member 72 can be rotatably set on the bottom plate 6. In this embodiment, a mounting bracket 722 is also provided at the first end of the connecting member 72 for fixing the connecting member 72 to the body. Specifically, the body of the electric circular saw is rotatably set on the mounting bracket 722, that is, the housing 1 and the mounting bracket 722 are rotatably connected. Preferably, the housing 1 and the mounting bracket 722 are connected in a manner of matching a pin hole and a rotating shaft.

[0067] In this embodiment, a first arc-shaped groove 721 is provided at the second end of the connecting member 72. The first locking member 73 passes through the first arc-shaped groove 721 and is fixedly disposed in the fixing hole 712 of the fixing plate 71. Preferably, the first locking member 73 is configured as a locking knob, which is an existing device and can be directly purchased and used. The locking knob can adjust the spacing between the fixing plate 71 and the connecting member 72 by rotating, thereby realizing the locking and loosening between the fixing plate 71 and the connecting member 72, and can cooperate with the first arc-shaped groove 721 to realize the adjustment of the rotation angle of the connecting member 72.

[0068] Still Figure 6 and Figure 7 As shown, a plurality of limiting holes 723 are provided on the angle adjustment mechanism 7. Specifically, the plurality of limiting holes 723 are arranged at intervals along the extension direction of the first arc groove 721, and the spacing between the plurality of limiting holes 723 and the first arc groove 721 is equal. At the same time, a positioning hole 711 is provided on the fixing plate 71. In this embodiment, the angle adjustment mechanism 7 also includes a pin shaft, which can pass through the limiting hole 723 and be inserted into the positioning hole 711, so that the angle between the saw blade and the bottom plate 6 can be quickly selected, which helps to improve the cutting efficiency. At the same time, it also helps to avoid the offset during cutting, so as to effectively ensure the cutting accuracy.

[0069] like Figure 6 , Figure 8 and Fig. 9 As shown, the depth adjustment mechanism 8 is arranged on the bottom plate 6 and is arranged opposite to the angle adjustment mechanism 7 along the second direction. The depth adjustment mechanism 8 is used to adjust the depth of the saw blade inserted into the bottom plate 6. Specifically, the depth adjustment mechanism 8 includes a depth frame 81 and an adjustment member 83, wherein the depth frame 81 is arranged on the bottom plate 6, an arc-shaped adjustment groove is arranged on the depth frame 81, and a scale 84 is arranged on the depth frame 81. The adjustment member 83 is arranged on the housing 1, and the adjustment member 83 can adjust the distance between the depth frame 81 and the housing 1, thereby adjusting the depth of the saw blade inserted into the bottom plate 6.

[0070] In some embodiments of the present application, the bottom plate 6 is provided with a second arc groove 62, and the depth frame 81 is rotatably connected to the bottom plate 6. At the same time, the depth adjustment mechanism 8 also includes a second locking member 82, which passes through the second arc groove 62 and is fixedly arranged on the depth frame 81, and the second locking member 82 is used to adjust the rotation angle of the depth frame 81. Specifically, a pin hole is provided on the bottom plate 6, and a third pin hole 811 is provided on the depth frame 81. By providing a rotating shaft passing through the pin hole and the third pin hole 811, the rotatable connection between the depth frame 81 and the bottom plate 6 can be achieved.

[0071] At this time, a second locking member 82 is provided on the depth frame 81, and the second locking member 82 can pass through the second arc groove 62. In this embodiment, the second locking member 82 has the same structure as the first locking member 73. The second locking member 82 can adjust the distance between the depth frame 81 and the bottom plate 6 by rotation, thereby realizing the locking and loosening between the depth frame 81 and the bottom plate 6, and can cooperate with the second arc groove 62 to realize the adjustment of the rotation angle of the depth frame 81. By rotatably connecting the depth frame 81 with the bottom plate 6, and providing the second arc groove 62 and the second locking member 82, the depth frame 81 connected to the housing 1 can rotate with the rotation of the angle adjustment mechanism 7. The depth adjustment structure cooperates with the angle adjustment mechanism 7 to realize the front and rear dual fixation of the fuselage, which helps to improve the stability of the fuselage and improve the accuracy of cutting when adjusting the angle.
