Description

Technical Field

[0001] This utility model relates to the field of cutting tool technology, and in particular to a safety auxiliary structure for an electric cutting tool. Background Technology

[0002] Electric cutting tools include various types such as beveling saws and electric saws. Among them, the beveling saw is a cutting tool that can cut both straight and beveled, and it is widely used in various industries. It can cut not only metal materials but also non-metal materials. When cutting a workpiece, the user holds the beveling saw handle with one hand and the workpiece with the other hand, so that the bottom of the workpiece rests on the cutting table of the beveling saw base and the back rests against the fixed grid, and the cutting operation can be carried out.

[0003] In existing technologies, during beveling operations, to improve workpiece cutting accuracy, it is often necessary to place the hand on the cutting table of the base to ensure that the workpiece does not shift during the cutting process. However, this operating method has a drawback: because the saw blade is tilted during beveling, the hand holding the workpiece is too close to the saw blade, which can easily cause safety accidents. To address this, when performing beveling operations on longer workpieces, users place the hand holding the workpiece away from the cutting table and use a movable guard on a fixed guard and an extension table on the base to limit the workpiece. However, because there is a certain gap in the height direction between the movable guard and the extension table of existing beveling saws, they usually cannot effectively limit thinner workpieces in the horizontal direction. As a result, the workpiece is prone to shift under the force of the hand during the cutting process, which affects the cutting accuracy. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned problems by providing a safety auxiliary structure for electric cutting tools, which has the advantage of providing effective support even for thinner workpieces.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a base, an extension platform, and a fixed support grid. The extension platform is disposed at the end of the base, and the fixed support grid is disposed on the base. The upper surface of the base is provided with a cutting table surface, and the upper surface of the extension platform is provided with an auxiliary support surface. The cutting table surface and the auxiliary support surface are coplanar in the horizontal direction to support the workpiece. A movable support grid is slidably disposed on the fixed support grid. The movable support grid has a downwardly extending extension portion that cooperates with the auxiliary support surface. The movable support grid and the extension portion cooperate to form a first abutment surface. The fixed support grid has a second abutment surface. The first abutment surface and the second abutment surface are coplanar in the vertical direction to support the workpiece.

[0006] Preferably, the first abutting surface includes a main abutting surface and an extension abutting surface, and the second abutting surface and the extension are both located below the main abutting surface.

[0007] Preferably, the extension platform is telescopically coupled with the base.

[0008] Preferably, the fixed rail is provided with a sliding groove arranged along the length direction, and the bottom of the movable rail is provided with a sliding part that slides in cooperation with the sliding groove.

[0009] Preferably, the sliding part is provided with a sliding groove, and the side wall of the sliding groove is provided with a slider that cooperates with the sliding groove, and the bottom of the slider is limited to cooperate with the bottom of the sliding groove.

[0010] Preferably, the fixed guardrail is provided with a first locking component for fixing the movable guardrail.

[0011] Preferably, the extension is located at the end of the movable gate.

[0012] Preferably, the extension extends vertically downward relative to the movable gate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This utility model provides a safety auxiliary structure for an electric cutting tool. When cutting long workpieces, the movable support grid needs to be moved to extend the effective support length of the abutment surface. Although moving the movable support grid will cause a gap between the bottom of the main abutment surface and the cutting table surface, thinner workpieces can be effectively supported by the second abutment surface and the extended abutment surface, thus solving the problem that the support grid cannot provide effective support for thinner workpieces. After the extended abutment surface provides effective support for thinner workpieces, it can prevent the workpiece from shifting under the force of the hand during the cutting process, thereby improving the accuracy when cutting thinner workpieces. In addition, the hand is safer because it is away from the saw blade, and there is no risk of the saw blade cutting the hand and causing a safety accident. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1-4 As shown, a safety auxiliary structure for an electric cutting tool includes a base 1, an extension platform 5, and a fixed support 2. The extension platform 5 is disposed at the end of the base 1, and the fixed support 2 is disposed on the base 1. The upper surface of the base 1 is provided with a cutting table 10, and the upper surface of the extension platform 5 is provided with an auxiliary support surface 50. The cutting table 10 and the auxiliary support surface 50 are coplanar in the horizontal direction to support the workpiece. A movable support 3 is slidably disposed on the fixed support 2. The movable support 3 has an extension portion 31 that extends downward and cooperates with the auxiliary support surface 50. The extension portion 31 is located at the end of the movable support 3 and extends vertically downward relative to the movable support 3. The movable support 3 and the extension portion 31 cooperate to form a first abutment surface 30. The fixed support 2 has a second abutment surface 20. The first abutment surface 30 and the second abutment surface 20 are coplanar in the vertical direction to support the workpiece.

[0022] The fixed rail 2 is provided with a sliding groove 21 arranged along the length direction, and the bottom of the movable rail 3 is provided with a sliding part that slides in cooperation with the sliding groove 21.

[0023] The first abutment surface 30 includes a main abutment surface 301 and an extension abutment surface 302. The second abutment surface 20 and the extension 31 are both located below the main abutment surface 301. Preferably, the height of the extension 31 is equal to the height of the fixed abutment 2, and the initial position between the movable abutment 3 and the fixed abutment 2 is such that the extension 31 and the end of the fixed abutment 2 are in a limiting contact engagement. When it is necessary to adjust the movable abutment 3, by pulling the movable abutment 3, the movable abutment 3 will move and cause the main abutment surface 301 to be lowered. The lower end creates a gap with the end face of the cutting table 10. When cutting thinner workpieces, the workpiece does not contact the main abutment surface 301, but the workpiece can be effectively supported by the second abutment surface 20 and the extension abutment surface 302. However, in the prior art, when cutting longer and thinner workpieces, the part of the workpiece outside the cutting table 10 is suspended in the air. Therefore, the abutment cannot provide effective support for the thinner workpiece, which causes the workpiece to easily deviate under the force of the hand during the cutting process, resulting in a decrease in cutting accuracy.

[0024] The front and / or rear faces of the sliding part are provided with a sliding groove 320. The front wall and / or the sliding groove 21 are provided with a slider 22 that cooperates with the sliding groove 320. The bottom of the slider 22 is limited to the bottom of the sliding groove 320. Through the limited cooperation between the slider 22 and the sliding groove 320, the movable rail 3 can move in the vertical direction.

[0025] The fixed rail 2 is provided with a first locking component 4 for fixing the movable rail 3. The first locking component 4 includes a first wrench 41 and a first bolt 42. The first bolt 42 is inserted into the slide groove 21. The first wrench 41 drives the first bolt 42 to reciprocate along the axial direction of the first bolt 42 at a first position and a second position.

[0026] When the first bolt 42 is in the first position, the movable guard 3 and the fixed guard 2 are in sliding engagement. At this time, the relative position between the movable guard 3 and the fixed guard 2 can be adjusted, so that workpieces of different lengths can have sufficient contact surface.

[0027] When the first bolt 42 is in the second position, the end of the first bolt 42 abuts against the movable guard 3, so that the movable guard 3 is fixedly engaged with the fixed guard 2. This prevents relative sliding between the movable guard 3 and the fixed guard 2 during the processing, thereby preventing interference and danger caused by the sliding between the fixed guard 2 and the movable guard 3.

[0028] An extension platform 5 is provided at the end of the base 1. The upper surface of the extension platform 5 has an auxiliary support surface 50 that cooperates with the cutting table surface 10. The extension platform 5 is telescopically connected with the base 1. The extension platform 5 is used to provide support in the vertical direction. The lower end surface of the extension abutment surface 302 is on the same horizontal plane as the auxiliary support surface 50.

[0029] The extension table 5 is movably provided with a baffle 51 at its end. The baffle 51 is used to restrict the sliding of the workpiece in the length direction of the slide groove 21, thereby improving the processing accuracy.

[0030] The extension platform 5 is equipped with a slide rod 52, which is slidably disposed in the base 1. In this application, there are two slide rods 52. The base 1 is provided with a second fastening assembly 6 for fixing the slide rod 52. The second fastening assembly 6 includes a second wrench 61 and a second bolt 62. The second wrench 61 drives the second bolt 62 to reciprocate between the third position and the fourth position along the axial direction of the second bolt 62.

[0031] When the second bolt 62 is in the third position, the slide bar 52 slides with the base 1, which can adjust the relative position between the extension table 5 and the base 1, so that workpieces of different lengths can have sufficient support surface;

[0032] When the second bolt 62 is in the fourth position, the end of the second bolt 62 abuts against the slide bar 52, so that the slide bar 52 is fixedly engaged with the base 1.

[0033] When cutting thin, long workpieces, by pulling the extension table 5 out relative to the base 1, an adjustable gap is formed between the extension table 5 and the base 1. This gap provides space for the user's hands, making the user more comfortable and safer while keeping them away from the saw blade. Although the workpiece does not contact the main abutment surface 301, the workpiece can be effectively supported by the second abutment surface 20 and the extension abutment surface 302. In contrast, in the prior art, when cutting long and thin workpieces, the part of the workpiece outside the cutting table 10 is suspended in the air. Therefore, the abutment cannot provide effective support for the thin workpiece, which can easily cause the workpiece to shift under the force of the hand during the cutting process, resulting in reduced cutting accuracy. Furthermore, placing the user's hands in the gap position keeps them away from the saw blade, making it safer and preventing accidents caused by the saw blade cutting the hand.
