[0022] The application will now be described in further detail with reference to the drawings. These drawings are simplified schematic diagrams which only show the basic structure of the application in a schematic manner, and thus only show the components relevant to the application.

[0023] In the description of the application, it should be noted that unless otherwise explicitly specified and limited, the terms "connected", "connected" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the application can be understood according to the specific circumstances.

[0024] Figure 1 、 Figure 2 、 Figure 3 and Figure 4 A high-stability electric circular saw base is shown in the drawings, which comprises a main shell 1, a lateral protective cover 2 movably assembled on the side wall of the main shell 1, an electric control type cutting circular saw 3 installed on the side wall of the main shell 1 inside the lateral protective cover 2, a lateral stability adjusting seat 4 provided on one side of the main shell 1, a side-hung dust collection box 5 installed on the side wall of the lateral stability adjusting seat 4, and a pull-out dust extraction pipe 6 installed on the side-hung dust collection box 5 and connected to the inside of the lateral protective cover 2.

[0025] In order to cooperate with the installation and adjustment, an embedded top guide rail 7 is fixedly assembled on the lateral stability adjusting seat 4.

[0026] In order to cooperate with the electric control translation, an electric control lead screw 71 for controlling the translation of the main shell 1 is installed inside the embedded top guide rail 7, and the main shell 1 is sleeved on the electric control lead screw 71 and threadedly assembled with the electric control lead screw 71 through an internally threaded mounting block 8 of the bottom integral structure.

[0027] The electric control lead screw 71 controls the translation adjustment of the internally threaded mounting block 8 along the inside of the embedded top guide rail 7 by rotating.

[0028] In order to cooperate with the movable assembly and angle adjustment, the main shell 1 has an integral lateral connecting boss 9 at the connecting end of the side wall in the lateral protective cover 2, the lateral protective cover 2 is movably assembled with the main shell 1 by being sleeved on the lateral connecting boss 9, and an angle adjusting support rod 10 is installed between the main shell 1 and the lateral protective cover 2.

[0029] The angle adjustment strut 10 controls the rotation adjustment of the lateral protective cover 2 along the lateral connecting boss 9 through extension and retraction. One end of the angle adjustment strut 10 is connected to the outside of the lateral protective cover 2, and the other end is connected to the outside of the main shell 1.

[0030] In order to match the infrared control, the infrared monitoring module 11 for controlling the angle adjustment strut 10 is fixedly arranged on the arc-shaped surface of the lateral protective cover 2.

[0031] The infrared monitoring module 11 monitors the two sides of the lateral protective cover 2 downwardly, and the infrared monitoring mode includes infrared temperature measurement or infrared distance measurement. When the infrared monitoring module 11 at the position detects that the temperature is high or the distance is short, the infrared monitoring module 11 controls the extension and retraction of the angle adjustment strut 10, so as to change the angle of the lateral protective cover 2, thereby reducing the gap and improving the blocking efficiency.

[0032] In order to match the synchronous extension and retraction control, the lateral extension hole 51 is formed in the side wall of the side-hung dust collecting box 5, the transversely arranged section of the pull-out dust extraction pipe 6 is inserted into the inside of the lateral extension hole 51 and is slidingly arranged with the side-hung dust collecting box 5, the inner side guide sealing piston 61 is fixedly arranged in the section of the pull-out dust extraction pipe 6 inside the side-hung dust collecting box 5, and the outer end of the pull-out dust extraction pipe 6 is fixedly communicated with the lateral protective cover 2 through the communication pipe.

[0033] When the electric control screw rod 71 rotates to drive the inner threaded mounting block 8 to translate, the lateral protective cover 2 drives the pull-out dust extraction pipe 6 to slide in the lateral extension hole 51, and then drives the inner side guide sealing piston 61 to slide in the side-hung dust collecting box 5. When the pull-out dust extraction pipe 6 is pulled out, the inner side guide sealing piston 61 expands the dust collecting space inside the side-hung dust collecting box 5 at this time. When the pull-out dust extraction pipe 6 is retracted, the inner side guide sealing piston 61 extrudes the dust collecting space inside the side-hung dust collecting box 5 inwardly at this time, so as to facilitate the extrusion and guide of the internal garbage outwardly.

[0034] In order to improve the installation and limiting stability, the telescopic limiting dowel 12 is elastically arranged at the top corner position of the lower end of the lateral stability adjusting seat 4, and the operation top hat 13 is arranged at the upper end of the telescopic limiting dowel 12.

[0035] The lateral stability adjusting seat 4 is internally provided with a lateral telescopic hole for elastically assembling the telescopic limiting pin 12. The telescopic limiting pin 12 is downwardly extruded by the extrusion spring inside the lateral telescopic hole, so that the telescopic limiting pin 12 can be conveniently inserted into the surface of the material to be cut. The telescopic limiting pin 12 is designed as a traceless nail, which can greatly reduce the influence on the surface of the material. The operation of the top cap 13 is to insert the telescopic limiting pin 12 into the material when the lateral stability adjusting seat 4 is placed on the surface of the material, so as to limit and fix the lateral stability adjusting seat 4.

[0036] In order to cooperate with manual control and carrying, the handle 14 for convenient control is fixedly assembled on the upper surface of the main shell 1.

[0037] When the main shell 1 is in the storage state, it is translated to the upper end of the lateral stability adjusting seat 4. People only need to hold the handle 14 to carry the entire device.

[0038] In order to cooperate with internal function expansion, the bottom expansion groove 15 is provided on the lower surface of the lateral stability adjusting seat 4.

[0039] As shown in Figure 5 and Figure 6 In order to cooperate with internal limiting, the internal limiting clamping groove 16 is provided on both sides of the bottom expansion groove 15.

[0040] The device for function expansion, such as the bottom track for convenient translation, is inserted through the opening on one side of the bottom expansion groove 15. The limiting of the telescopic limiting pin 12 is avoided through the bottom track to drive the entire base to translate. The bottom guide plate can also be inserted through the opening on one side of the bottom expansion groove 15. After the electric circular saw cuts a strip-shaped groove, the vertically placed guide plate at the lower end of the bottom guide plate is inserted into the strip-shaped groove, and then the translation cutting is carried out along the strip-shaped groove. The guide wheel inside the bottom guide plate reduces the friction.

[0041] Working principle: people place the device on the surface of the material to be cut. The electric control type cutting circular saw 3 cuts a strip-shaped cutting groove on the surface of the material. Finally, the telescopic limiting pin 12 at the lower end of the lateral stability adjusting seat 4 is inserted into the surface of the material. Then, the lateral stability adjusting seat 4 is turned over and attached to the surface of the material. At the same time, the main shell 1 at the upper end of the lateral stability adjusting seat 4 is translated along the embedded top guide rail 7. At the same time, the electric control type cutting circular saw 3 is opened for translation cutting. At the same time of translation cutting, the side hanging type dust collecting box 5 is translated and telescoped at one side of the side hanging type dust collecting box 5, driven by the side protection cover 2 and the pull-out type dust collecting pipe 6. The dust collecting inside the side protection cover 2 is quickly sucked into the side hanging type dust collecting box 5 through the externally hanging type gas pump at the end of the side hanging type dust collecting box 5.

[0042] With the above ideal embodiments according to the present application as the inspiration, through the above description, relevant staff can make various changes and modifications without deviating from the technical idea of the present application. The technical scope of the present application is not limited to the content of the specification, and must be determined according to the scope of the claims.
