[0024] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0025] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0026] This embodiment mainly describes the support for a precision angle grinder, as detailed below:

[0027] like Figures 1-3 As shown, the precision angle grinder stand includes a base 4 and a support base 10. The base 4 has symmetrical upright plates 13 on both sides. One upright plate 13 has two screw holes. When the base 4 is placed on the rib to be cut, the corresponding positioning bolt 3 passes through the screw hole and abuts against the rib. Under the continuous pushing of the positioning bolt 3, the rib abuts against the inner wall of the other upright plate 13, so that the base 4 is placed stably, which makes it convenient for the user to cut the rib.

[0028] The other side of the upright plate 13 is provided with a first extension plate 12 extending outward, and correspondingly, the support base 10 is provided with a second extension plate 11 extending towards the base 4. The first extension plate 12 and the second extension plate 11 are arranged in parallel and intersecting with each other, and the second extension plate 11 does not abut against the upright plate 13.

[0029] A slide rail 15 and a lead screw 19 are fixedly installed on the first extension plate 13. The slide rail 15 is fixedly installed on the first extension plate 12 by screws.

[0030] As Figure 4 shown in the figure, the lead screw 19 is provided with a limiting groove 20, the first extension plate 12 is provided with a sleeve ring 18, the sleeve ring 18 is sleeved on the limiting groove 20, which ensures the rotation of the lead screw 19 while limiting the back and forth sliding of the lead screw 19, the sleeve ring 18 is provided with a fixed knob 17, when the rotation adjustment of the lead screw 19 is completed, the lead screw 19 can be locked by tightening the fixed knob 17, which prevents unnecessary rotation of the lead screw 19 during work, ensuring the stability of the angle grinder position, in the embodiment, the axial direction of the lead screw 19 is set as the X axis.

[0031] As Figure 3 shown in the figure, the second extension plate 11 is provided with a sliding block 16 and a lead screw nut 26, the sliding block 16 is arranged on the sliding rail 15, specifically, the both sides of the sliding rail 15 are provided with a strip-shaped groove 25, the sliding block 16 is fixedly arranged on the second extension plate 11 by screwing, the sliding block 16 is provided with a hook 24 corresponding to the groove 25, the sliding block 16 is inserted into the groove 25 through the hook 24, so that the sliding block 16 can slide back and forth on the sliding rail 15.

[0032] The both ends of the sliding rail 15 are fixedly provided with a limiting block 14 through a screw, the maximum sliding range of the sliding block 16 on the sliding rail 15 is limited by the limiting block 14.

[0033] The lead screw nut 26 is fixedly arranged at one end of the second extension plate 11 by screwing, and the bottom of the lead screw nut 26 does not abut against the first extension plate 12.

[0034] The lead screw nut 26 is sleeved on the lead screw 19 by thread connection, when the lead screw 19 is rotated, because the sleeve ring 18 limits the back and forth movement of the lead screw 19 on the X axis, the lead screw nut 26 will drive the bracket seat 10 to slide back and forth along the X axis according to the screw transmission principle, thereby realizing the position adjustment of the angle grinder in the X axis direction.

[0035] As Figure 5 , Figure 6 shown in the figure, the bracket seat 10 is provided with a moving seat 6, the moving seat 6 is fixedly arranged on the bracket seat 10 by screwing.

[0036] As Figure 6 shown in the figure, the moving seat 6 is provided with two perforations 27, each perforation 27 is provided with a sliding rod 5, the two sliding rods 5 slide back and forth synchronously in the perforation 27 to adjust the cutting position of the angle grinder, the axial direction of the sliding rod 5 is set as the Y axis.

[0037] One side of the perforation 27 is provided with a locking knob 21, when the sliding rod 5 is adjusted to the appropriate position in the perforation 27 of the angle grinder, the locking knob 21 is tightened to fix the position of the sliding rod 5 in the perforation 27, so that the user can use the angle grinder more stably.

[0038] AsFigure 7 As shown, a connecting seat 23 is provided at one end of the slide rod 5. The connecting seat 23 is located above the second extension plate 11 and does not abut against the second extension plate 11.

[0039] like Figure 8 As shown, a mounting base 9 is also hinged to the connecting base 23. The mounting base 9 is used to fix the angle grinder. Specifically, the mounting base 9 is provided with a positioning base 22 and auxiliary bolts 8. There are two positioning bases 22 and two auxiliary bolts 8. One end of the positioning base 22 is set on the mounting base 9 and fixed by screws. The other end is provided with bolts for fixing the angle grinder. After the angle grinder is fixed by the positioning base 22, the auxiliary bolts 8 are rotated from the other side so that the two auxiliary bolts 8 abut against the angle grinder, making the installation of the angle grinder more stable.

[0040] The mounting base 9 is equipped with a handle 1, and a return spring 7 is provided between the mounting base 9 and the connecting base 23. When normally placed, the return spring 7 is in a contracted state. When the user uses the angle grinder, the user rotates the mounting base 9 by the handle 1, and the return spring 7 undergoes elastic deformation, changing from a contracted state to a stretched state. After use, the mounting base 9 returns to the contracted state from the stretched state under the elastic deformation of the return spring 7, preventing accidents caused by the angle grinder slipping out of the user's hand.

[0041] A limiting bolt 2 is fixedly installed on one side of the mounting base 9. The limiting bolt 2 rotates synchronously with the mounting base 9. During the rotation of the mounting base 9, one end of the limiting bolt 2 will abut against the connecting seat 23 to limit the maximum rotation range of the mounting base 9 and prevent the user from over-rotating the angle grinder and causing an accident.

[0042] In summary, the usage process of the precision angle grinder bracket is as follows: When the angle grinder is needed for cutting operations, the first step is to fix the angle grinder on the mounting base 9. Then, adjust the positioning in the X-axis direction. According to the cutting requirements, rotate the lead screw 19 so that the lead screw nut 26 sleeved on the lead screw 19 slides along the X-axis direction. Because the lead screw nut 26 and the slider 16 are fixedly connected to the bracket base 10, and the limit blocks 14 at both ends of the slide rail 15 will ensure that the slider 16 slides on the slide rail 15, the bracket base 10 will move along the slide rail 15 in the X-axis direction as the lead screw nut 26 moves, thereby driving the mounting base 9 and the angle grinder to move to the appropriate position in the X-axis direction. After reaching the required position, tighten the fixing knob 17 on the collar 18 to fix the lead screw 19 and prevent the position of the angle grinder from changing due to the rotation of the lead screw 19 during the cutting process.

[0043] After the positioning of the angle grinder in the X-axis direction is completed, the positioning adjustment in the Y-axis direction is performed, the mounting base 9 is axially pushed in the moving base 6 along the slide rod 5, and after the angle grinder on the mounting base 9 is adjusted to the appropriate position in the Y-axis direction, the locking knob 21 on one side of the moving base 6 is locked to fix the positioning of the angle grinder in the Y-axis.

[0044] After the positioning in the X-axis and Y-axis directions is completed, the angle grinder can be used for precise cutting operation, when the cutting is completed, the mounting base 9 is reset under the elastic action of the reset spring 7 between the mounting base 9 and the connecting base 23, and then the fixing knob 17 and the locking knob 21 are loosened, so that the angle grinder can be adjusted and reset in the X-axis and Y directions, and the next operation is facilitated.
