[0002] In actual construction projects, the walls are covered with putty. The conventional method is for workers to grind the walls with handheld sandpaper, but this method is time-consuming and labor-intensive, and the grinding is uneven. In order to avoid this drawback, electric grinding devices are now used to achieve efficient operation. However, existing electric grinding devices, such as angle grinders, are all one-piece designs, and the grinding angle of the machine must be adjusted by hand during use. When the machine needs to be tilted at a certain angle for a long time to operate, the handheld method is not only laborious, but the machine cannot be stabilized at the specified angle. This is not only inefficient, but also affects the quality of construction. Therefore, it is necessary to improve the existing electric grinding devices to solve the above problems.

[0032] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without inventive work.

[0033] To simplify the drawings, only the parts relevant to the utility model are schematically shown in each figure; they do not represent the actual structure of the product. Furthermore, to simplify the drawings and facilitate understanding, in some figures, only one of the components with the same structure or function is schematically shown or labeled. In this document, "one" not only means "only one" but also "more than one," and "several" includes "two" and "more than two."

[0034] It should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0035] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0036] like Figures 1 to 7 As shown, an automatic grinding machine for construction includes a grinding body 1 with a limiting groove 2; a bracket 3 is located on one side of the grinding body 1; a connecting member 4 is movably set on the bracket 3, and the grinding body 1 is rotatably set on the bracket 3, and the rotation axis of the grinding body 1 is parallel to the moving direction of the connecting member 4. The connecting member 4 has a limiting portion 5. After the connecting member 4 moves, the limiting portion 5 clamps or cancels the clamping of the limiting groove 2, so that the grinding body 1 is locked or rotates freely.

[0037] In this embodiment, in order to solve the problem in the related art that the electric grinding device used in construction is not convenient to be fixed at a specified angle for a long time for grinding, a limit groove 2 is opened on the grinding body 1, and the limit part 5 of the connecting member 4 is used to cooperate with it. When the connecting member 4 is moved, the limit part 5 is stuck in or disengaged from the limit groove 2, so that the grinding body 1 can adjust its own angle easily and quickly, and lock it at the specified angle, avoiding the laborious and unstable problems caused by manually holding the grinding body 1 at an inclined angle for a long time, and adapting to different work scenarios and requirements.

[0038] Specifically, the grinding body 1 mainly includes a grinding disc and a drive motor. Similar to the existing angle grinder body, when there is no need to adjust the inclination angle of the grinding body 1, it can be used normally. When the angle needs to be adjusted, you only need to simply push the connecting part 4 to make the limiting part 5 and the limiting groove 2 stuck or disengaged, so as to realize the locking and free rotation state switching of the grinding body 1. There is no need for complicated operation procedures, the operation is simple and fast, and it can adapt well to different work scenarios and requirements.

[0039] Furthermore, the grinding body 1 has a through hole 1 6, and the bracket 3 has a through hole 2 7. Both ends of the through hole 1 6 abut against the bracket 3. The connecting member 4 passes through the through hole 1 6 and the through hole 2 7 in sequence and is movably set on the bracket 3. The limiting groove 1 2 is located on the inner wall of the through hole 1 6, and the limiting portion 1 5 is located on the side wall of the connecting member 4.

[0040] In this embodiment, the bracket 3 is C-shaped. A through-hole 1 (6) extends through the grinding body 1, and a corresponding through-hole 2 (7) is provided on the bracket 3. The ends of through-hole 1 (6) are designed to tightly abut against the bracket 3, ensuring that the movement of the connector 4 does not affect the grinding body 1 and enhancing the stability of the grinding body 1 during rotation. The connector 4 passes through through-hole 1 (6) and through-hole 2 (7) sequentially, allowing for movement on the bracket 3. A stopper 2 (2) is provided on the inner wall of through-hole 1 (6). A protruding portion on the sidewall of the connector 4 serves as a stopper 5. As the connector 4 moves within through-hole 1 (6) and through-hole 2 (7), the stopper 5 can align or misalign with the stopper 2. When misaligned, the stopper 5 does not interfere with the stopper 2, allowing the grinding body 1 to rotate freely for angular adjustment. Once adjusted, the stopper 5 can be aligned with the stopper 2. When aligned, it engages the stopper 2, locking the grinding body 1 in place and preventing rotation. Realize the state switching of the grinding body 1. Realize the state switching of the grinding body 1.

[0041] Furthermore, the bracket 3 has a second limiting groove 8 , and the connecting member 4 also has a second limiting portion 9 , which is used to clamp the second limiting groove 8 .

[0042] In this embodiment, the connection member 4 and the bracket 3 also have a matching limit portion 2 9 and a limit groove 2 8. The principle is the same as that of the limit portion 1 5 and the limit groove 1 2. The function is to prevent the connection member 4 from rotating itself and affecting the tilt angle of the grinding body 1.

[0043] Furthermore, when the connecting member 4 moves, the second limiting portion 9 remains clamped in the second limiting groove 8.

[0044] In this embodiment, the second limiting portion 9 can be configured so that no matter whether the connecting member 4 moves or not, the second limiting portion 9 is always stuck in the second limiting groove 8, so that the connecting member 4 can only move but not rotate, thereby avoiding the influence of the rotation of the connecting member 4 itself.

[0045] Furthermore, when the connecting member 4 moves, the second limiting portion 9 is stuck in or disengaged from the second limiting groove 8.

[0046] In this embodiment, the limiting portion 2 9 can also be configured so that after the connecting member 4 moves to the limiting portion 1 5 and disengages from the limiting groove 1 2, the limiting portion 2 9 also disengages from the limiting groove 2 8. At this time, the connecting member 4 itself can also rotate. The function is that after the grinding body 1 is adjusted to a good angle, the limiting portion 1 5 can be snapped into the limiting groove 1 2 by rotating the connecting member 4, thereby avoiding the special situation that the limiting portion 1 5 cannot be snapped into the limiting groove 2 after the grinding body 1 is adjusted to a good angle.

[0047] Furthermore, the bracket 3 also has a receiving groove 10, which is located on one side or both sides of the second limiting groove 8 and is used to accommodate the moved second limiting portion 9.

[0048] In this embodiment, when the connector 4 moves, the second limiter 9 also moves. The bracket 3 has an accommodating slot 10 to provide space for the second limiter 9 to move. Furthermore, accommodating slots 10 are provided on both sides of the second limiter 8, allowing the second limiter 9 to move in either direction. This allows the connector 4 to move forward or backward, driving the first limiter 5 out of the first limiter 2. This means that when adjusting the angle of the grinding body 1, the movement direction of the connector 4 is no longer limited; simply moving the connector 4 can lock or unlock the grinding body 1.

[0049] Furthermore, a cover 11 is included. One end of the connecting member 4 is provided with the cover 11. One end of the elastic member 12 acts on the cover 11, and the other end acts on the bracket 3 to provide a force for restoring the cover 11.

[0050] In this embodiment, a cover 11 is mounted on one end of the connector 4 to prevent it from accidentally falling off the bracket 3. An elastic member 12 is also provided, one end of which is connected to the cover 11 and the other end to the bracket 3. When the connector 4 moves, the elastic member 12 is compressed. When the external force disappears, the elastic force of the elastic member 12 causes the cover 11 to automatically return the connector 4 to its original position. For example, after pushing the connector 4 to lock or freely rotate the grinding body 1, releasing the connector 4 will quickly pull the connector 4 back to its original position, facilitating the next operation.

[0051] Furthermore, a cover 11 is also provided at the other end of the connecting member 4 .

[0052] In this embodiment, covers 11 are provided at both ends of the connector 4 to further enhance the stability and safety of the connector 4. The covers 11 at both ends are connected to elastic members 12. When the connector 4 moves, the elastic members 12 at both ends are compressed simultaneously. When the external force disappears, the elastic members 12 at both ends work together to allow the connector 4 to automatically return to its original position more smoothly.

[0053] Furthermore, the cover is provided with an anti-slip groove 13 .

[0054] In this embodiment, anti-slip grooves 13 are machined on the surface of the cover 11. When operating the connector 4, the operator can use their fingers or tools to contact the anti-slip grooves 13, increasing friction and making it easier to push or pull the connector 4. The shape and depth of the anti-slip grooves 13 can be designed according to actual operating requirements to improve operational comfort and efficiency.

[0055] Furthermore, a handle 14 is provided on the bracket 3 , and the handle 14 has an anti-slip layer 15 .

[0056] In this embodiment, a handle 14 is mounted on the bracket 3. The shape and size of the handle 14 are ergonomically designed to facilitate gripping by the operator. The surface of the handle 14 is covered with an anti-slip layer 15, such as a rubber anti-slip cover, which increases friction between the operator's hand and the handle 14, preventing slipping during operation of the grinder and improving operational safety and stability.

[0057] In summary, the automatic building sander mainly consists of a sanding body 1, a bracket 3, a connecting piece 4, a cover 11, an elastic piece 12 and a handle 14. The sanding body 1 is located on one side of the bracket 3, and the various components cooperate with each other to achieve efficient building material sanding.

[0058] When using an automatic construction sander, the operator first grasps handle 14 and aligns the sanding body 1 with the surface of the building material to be sanded. Initially, the sanding body 1 is locked, preventing rotation, allowing precise, fixed-point sanding. To tilt the sanding body 1, the operator pushes connector 4, causing limiter 1 5 to unblock limiter 1 2. The sanding body 1 can then adjust its tilt angle to suit the specific situation. Releasing connector 4 automatically resets the lock on the sanding body 1, preparing it for the next operation.

[0059] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
