Description

Technical Field

[0001] This utility model relates to the field of grinding machine technology, and in particular to a grinding machine depth probing support device. Background Technology

[0002] In many professional fields such as building decoration, wall treatment and woodworking, sanders are undoubtedly an extremely common and indispensable tool. In the building decoration process, whether it is the interior decoration of new buildings or the renovation of old houses, sanders play a vital role.

[0003] With existing sanders, workers need to firmly grip the handle and move their arms to control the sanding disc to slide across the wall, thus sanding the wall surface evenly and achieving the desired sanding effect.

[0004] However, when facing large or high wall areas, workers often find it difficult to move the sanding disc smoothly to all corners and edges of the wall due to the short handheld portion of the disc. This makes it impossible to perform a comprehensive and detailed sanding of the entire wall surface, which not only affects the efficiency of the sanding operation but may also lead to uneven sanding results and affect the final wall surface quality. Utility Model Content

[0005] This addresses the technical problem of existing sanders having a short handheld part that makes it difficult to move the sanding disc smoothly to various corners and edges of the wall, thus preventing the entire wall surface from being sanded thoroughly and meticulously.

[0006] The technical solution of this utility model is as follows: a grinding machine depth probing support device, including a grinding machine body; it also includes an extension rod and an angle adjustment component; the upper end of the grinding machine body is fixedly connected to the grinding machine body, a handle is provided on one side of the connecting block, an angle adjustment component is provided on one side of the connecting block, an extension rod for lengthening the handle is provided on one side of the handle, an extension sleeve is slidably connected to the outside of the extension rod, an elastic clamping block is fixedly connected to one side of the extension sleeve, a fixing ring is threadedly connected to one side of the elastic clamping block, a first spring is fixedly connected to the inside of the extension rod, a movable block is fixedly connected to one side of the first spring, a pressing block is fixedly connected to one side of the movable block, and a locking block is fixedly connected to one side of the movable block.

[0007] Preferably, the extension rod has a slot, and the movable block is slidably connected to the inside of the extension rod through the slot.

[0008] Preferably, the handle has a second slot, and the locking block is engaged with the inside of the handle through a third slot.

[0009] Preferably, the angle adjustment assembly includes a second spring, a second spring is fixedly connected to the inner side of the connecting block, a first gear is fixedly connected to one side of the second spring, a limit block is fixedly connected to the outer side of the first gear, a rotating rod is provided on one side of the first gear, and a second gear is fixedly connected to one side of the handle, with the second gear meshing with the first gear.

[0010] Preferably, a groove three is provided on the inner side of the connecting block, and the first toothed disc is slidably connected to the inner side of the connecting block through the groove three.

[0011] Preferably, a slot four is provided on one side of the handle, and the rotating rod is movably connected to the inside of the handle through the slot four.

[0012] Preferably, the connecting block has a slot five, and the limiting block is slidably connected to the inner side of the connecting block through the slot five.

[0013] The beneficial effects of this utility model are as follows: Compared with traditional sanders, the handheld part is too short, making it difficult to move the sanding disc smoothly to various corners and edges of the wall, thus preventing a comprehensive and detailed sanding of the entire wall surface. This device, by inserting an extension rod into the handle, uses a beveled design on one side of the locking block. The handle presses against the locking block, causing it to slide. The locking block drives the movable block to slide, which in turn presses against the first spring. When the extension rod is in place, the first spring loses pressure, causing the first spring to slide. The movable block then drives the locking block to slide, allowing the locking block to engage with the groove on the handle, thereby extending the handheld length. By rotating the fixing ring, the fixing ring is disengaged from the elastic clamp, releasing the fixed connection to the extension sleeve. The extension sleeve is then pulled to slide outside the extension rod, allowing for readjustment of the handheld length. This enables comprehensive sanding of the wall surface, improving sanding efficiency and quality. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-6This utility model provides an embodiment of a grinding machine depth probing support device, including a grinding machine body 1; it also includes an extension rod 401 and an angle adjustment component; the upper end of the grinding machine body 1 is fixedly connected to the grinding machine body 1, a handle 3 is provided on one side of the connecting block 2, an angle adjustment component is provided on one side of the connecting block 2, an extension rod 401 for lengthening the handle 3 is provided on one side of the handle 3, an extension sleeve 402 is slidably connected to the outer side of the extension rod 401, an elastic clamping block 403 is fixedly connected to one side of the extension sleeve 402, a fixing ring 404 is threadedly connected to one side of the elastic clamping block 403, and a first spring 405 is fixedly connected to the inner side of the extension rod 401. A movable block 406 is fixedly connected to one side of the handle 5. A push block 407 is fixedly connected to one side of the movable block 406. A locking block 408 is fixedly connected to one side of the movable block 406. A groove is provided on the extension rod 401. The movable block 406 is slidably connected to the inner side of the extension rod 401 through the groove. The groove on the extension rod 401 allows the movable block 406 to slide and be slidably connected to the inner side of the extension rod 401, thus providing a guiding and limiting effect for the movable block 406. A groove is provided on the handle 3. The locking block 408 is engaged with the inner side of the handle 3 through the groove. The groove on the handle 3 allows the locking block 408 to engage with the inner side of the handle 3, thus providing a guiding and limiting effect for the handle 3. The extension rod 401 is fixed by inserting it into the handle 3. Because one side of the locking block 408 is beveled, the handle 3 presses against the locking block 408, causing it to slide. The locking block 408 then drives the movable block 406 to slide, which in turn presses against the first spring 405. When the extension rod 401 is fully installed, the first spring 405 loses pressure, causing the movable block 406 to slide. The movable block 406 then drives the locking block 408 to slide, causing the locking block 408 to engage with the slot on the handle 3, thus extending the handheld length. Rotating the fixing ring 404 disengages it from the elastic clamp 403, thereby releasing the locking mechanism. For the fixed connection of the extension sleeve 402, pull the extension sleeve 402 to slide outside the extension rod 401, thereby readjusting the handheld length. Then rotate the fixing ring 404 to cause the elastic clamp 403 to retract and clamp the extension rod 401, thereby fixing the extension sleeve 402. When disassembling the extension rod 401, press the push block 407. The push block 407 drives the movable block 406 to move. The movable block 406 squeezes the first spring 405. The movable block 406 drives the locking block 408 to move, causing the locking block 408 to disengage from the slot 2 on the handle 3, releasing the limiting fixation of the extension rod 401. Then pull the extension rod 401 to pull it out, completing the disassembly.

[0023] Please see Figures 5-6In this embodiment, the angle adjustment assembly includes a second spring 501. The second spring 501 is fixedly connected to the inner side of the connecting block 2. A first gear 502 is fixedly connected to one side of the second spring 501. A limit block 503 is fixedly connected to the outer side of the first gear 502. A rotating rod 504 is provided on one side of the first gear 502. A second gear 505 is fixedly connected to one side of the handle 3. The second gear 505 meshes with the first gear 502. A groove three is provided on the inner side of the connecting block 2. The first gear 502 is slidably connected to the inner side of the connecting block 2 through the groove three. The groove three on the inner side of the connecting block 2 allows the first gear 502 to... 502 is slidably connected to the inner side of the connecting block 2, thereby guiding and limiting the first gear 502. A slot four is opened on one side of the handle 3, and the rotating rod 504 is movably connected to the inner side of the handle 3 through the slot four. The slot four on one side of the handle 3 allows the rotating rod 504 to be movably connected to the inner side of the handle 3, thereby limiting the handle 3. A slot five is opened on the connecting block 2, and the limiting block 503 is slidably connected to the inner side of the connecting block 2 through the slot five. The slot five on the inner side of the connecting block 2 allows the limiting block 503 to be slidably connected to the connecting block 2, thereby limiting the first gear 502 and preventing it from rotating.

[0024] During operation, pressing the rotating rod 504 causes the first gear plate 502 to slide, which in turn causes the limiting block 503 to slide. The first gear plate 502 then presses against the second spring 501, causing it to disengage from the second gear plate 505, thus releasing the limiting fixation on the handle 3. Then, rotating the handle 3 causes the second gear plate 505 to rotate. When the handle 3 rotates to a suitable angle, releasing the rotating rod 504 allows the second spring 501 to slide the first gear plate 502. When the first gear 502 moves, it drives the limiting block 503 to slide. The limiting block 503 drives the rotating rod 504 to slide inside the handle 3, so that the first gear 502 and the second gear 505 mesh, thereby fixing and limiting the handle 3. When the grinding distance is extended, the extension rod 401 is inserted into the handle 3. Since one side of the locking block 408 is designed with a slope, the handle 3 presses against the locking block 408, causing the locking block 408 to slide. The locking block 408 drives the movable block 406 to slide, and the movable block 406 presses against the first spring 405. When the extension rod 401 is installed in place, the first spring 405 loses pressure, causing the movable block 406 to slide. The movable block 406 then causes the locking block 408 to slide, engaging with the slot 2 on the handle 3, thereby extending the handheld length. By rotating the fixing ring 404, the fixing ring 404 disengages from the elastic clamp 403, thus releasing the fixed connection to the extension sleeve 402. Pulling the extension sleeve 402 to slide outside the extension rod 401 allows for readjustment of the handheld length. Rotating the fixing ring 404 causes the elastic clamping block 403 to retract and clamp the extension rod 401, thereby fixing the extension sleeve 402. When disassembling the extension rod 401, by pressing the pressing block 407, the pressing block 407 drives the movable block 406 to move. The movable block 406 squeezes the first spring 405, and the movable block 406 drives the locking block 408 to move, so that the locking block 408 disengages from the slot 2 on the handle 3, releasing the limiting fixation of the extension rod 401. Then, pull the extension rod 401 to pull it out, completing the disassembly.

[0025] Through the above steps, by inserting the extension rod 401 into the handle 3, the handle 3 presses against the locking block 408 due to its beveled design, causing the locking block 408 to slide. The locking block 408 then drives the movable block 406 to slide, which in turn presses against the first spring 405. When the extension rod 401 is fully installed, the first spring 405 loses pressure, causing the movable block 406 to slide. The movable block 406 then drives the locking block 408 to slide, causing the locking block 408 to engage with the slot on the handle 3, thus extending the handheld length. By rotating the fixing ring 404, the fixing ring 404 disengages from the elastic clamp 403, thereby releasing the extension rod. The long sliding sleeve 402 is fixedly connected. Pulling the extended sliding sleeve 402 to slide it outside the extension rod 401 allows for readjustment of the handheld length. Then, rotating the fixing ring 404 causes the elastic clamp 403 to retract and clamp the extension rod 401, thus fixing the extended sliding sleeve 402. When disassembling the extension rod 401, pressing the push block 407 causes the push block 407 to move the movable block 406. The movable block 406 presses against the first spring 405, causing the movable block 406 to move the locking block 408, disengaging the locking block 408 from the groove on the handle 3 and releasing the limiting fixation of the extension rod 401. Then, pulling the extension rod 401 pulls it out, completing the disassembly.
