[0017] The present invention will be further described below with reference to specific embodiments. The accompanying drawings are for illustrative purposes only, representing schematic diagrams rather than actual physical objects, and should not be construed as limiting the present invention. To better illustrate the embodiments of the present invention, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0018] Example 1 like Figure 1-6 As shown, this utility model provides a multifunctional composite sander, including a sander body 10, with movable grooves 20 fixed on both sides of the sander body 10; an auxiliary grip component 30, which is disposed in the movable grooves 20 for gripping the sander body 10; and an angle limiting component 40, which is connected to the bottom of the auxiliary grip component 30 for angle positioning of the auxiliary grip component 30.

[0019] This utility model discloses a multi-functional composite sander. The auxiliary grip component 30 is connected in the movable slot 20. When needed, the auxiliary grip component 30 can be flipped to provide multiple gripping points during sanding. The user can choose the appropriate gripping point according to actual needs. At the same time, the angle limiting component 40 can be used to adjust the angle of the auxiliary grip component 30, thereby improving the flexibility of the sander.

[0020] Furthermore, in another embodiment, the angle limiting component 40 includes a rotating disk 401, a positioning hole 402, a through hole 403, a through rod 404, a limiting spring 405, and a pull rod 406. The rotating disk 401 is rotatably connected to the inner wall of the movable groove 20 via a movable shaft. Several positioning holes 402 are evenly provided on the rotating disk 401. The through hole 403 is provided in the movable groove 20. The through rod 404 passes through the movable groove 20, and the end of the through rod 404 away from the rotating disk 401 is detachably connected to the pull rod 406. The pull rod 406 has a preset hole for fixing the through rod 404. A baffle 4041 is provided at the end of the through rod 404 near the outer wall of the movable groove 20.

[0021] The limiting spring 405 is sleeved on the outside of the through rod 404. When it is necessary to adjust the angle of the auxiliary grip component 30, the relevant personnel can pull the pull rod 406, causing the through rod 404 to move away from the rotating disk 401. At this time, the baffle 4041 compresses the limiting spring 405, and the other end of the through rod 404 disengages from the positioning hole 402. The rotating disk 401 is released from its fixed state. Subsequently, the relevant personnel can rotate the auxiliary grip component 30, and the rotating disk 401 rotates synchronously with the auxiliary grip component 30. After rotating to the required angle, the pull rod 406 is released, and the limiting spring 405, under the action of elastic restoring force, moves the through rod 404 away from the rotating disk 401. 4. Insert the rod into the corresponding positioning hole 402 to re-fix the rotating disk 401, thereby completing the angle positioning of the auxiliary grip component 30. This structural design makes the angle adjustment operation convenient and efficient. Moreover, by setting multiple positioning holes 402, it can meet the diverse needs of the angle of the auxiliary grip component 30 in different working scenarios, further improving the flexibility and adaptability of the sander during use. It is worth noting that when the pull rod 406 is loosened, the through rod 404 will not be accurately inserted into the positioning hole 402. During the adjustment process, relevant personnel need to manually position the through rod 404 with the positioning hole 402.

[0022] Furthermore, in another embodiment, the auxiliary grip assembly 30 includes an auxiliary grip rod 301, a connecting rod 302, a fixing groove 303, and a movable locking block 304. The connecting rod 302 is fixed to the middle of the rotating disk 401. The auxiliary grip rod 301 is fixed above the connecting rod 302. The fixing groove 303 is opened at one end of the connecting rod 302 near the auxiliary grip rod 301. The movable locking block 304 is rotatably connected to the middle of the top of the movable groove 20. The movable locking block 304 and the fixing groove 303 cooperate with each other to fix the connecting rod 302.

[0023] When the auxiliary grip component 30 is needed, the operator can rotate the movable locking blocks 304 to both sides to disengage it from the fixed slot 303. At this time, the connecting rod 302 is released from its fixed position, and the auxiliary grip rod 301 can be rotated downwards around the rotating disk 401. After the auxiliary grip rod 301 is rotated to the appropriate position, it can be fixed in place by cooperating with the angle limiting component 40. The auxiliary grip rod 301 allows the operator to select the gripping point according to actual needs, bringing convenience to the operator. In addition, when the auxiliary grip rod 301 is not in use, the operator can rotate the auxiliary grip rod 301 upwards and then lock it into the fixed slot 303 by the movable locking blocks 304 to fix the auxiliary grip rod 301 in place. This combination of folding and fixing structure not only saves storage space for the sander, but also allows for quick switching of the auxiliary grip component's usage state according to operational needs, enhancing the practicality of the equipment.

[0024] Furthermore, in another embodiment, the pull rod 406 and the through rod 404 are fixed together by bolts.

[0025] This fixing method facilitates the disassembly of the pull rod 406 by relevant personnel. After the pull rod 406 is removed, the limit spring 405 can be replaced.

[0026] Furthermore, in another embodiment, a positioning groove 407 is provided inside the rotating disk 401, and a biting block 408 is provided at the upper and lower ends of the rotating disk 401. A positioning block 409 is provided on the side of the biting block 408 near the rotating disk 401.

[0027] The positioning block 409 is engaged in the positioning groove 407 in the rotating disk 401. During the rotation of the rotating disk 401, it can limit the rotation of the rotating disk 401 and ensure the stability of the rotating disk 401 during the rotation process.

[0028] Furthermore, in another embodiment, the sander body 10 is provided with a gripping rod 50 at one end, and the gripping rod 50 is provided with an anti-slip groove 501.

[0029] The anti-slip groove 501 effectively increases the friction between the operator's palm and the grip bar 50, preventing slippage caused by sweaty hands or equipment vibration during sanding operations, thereby improving grip stability and safety during operation.

[0030] Furthermore, in another embodiment, there are two movable blocks 304. The movable blocks 304 are connected to the movable groove 20 by threaded posts. The movable groove 20 has corresponding threaded grooves. The end of the movable blocks 304 near the connecting rod 302 is semi-circular. The contact surface of the two movable blocks 304 is made of magnetic material. The ends of the two movable blocks 304 near the connecting rod 302 are fixed by magnetic adsorption.

[0031] When it is necessary to fix the connecting rod 302, the two movable locking blocks 304 are attracted to each other by magnetic material, and their semi-circular ends can fit tightly against the outer wall of the connecting rod 302, thus forming a stable clamping of the connecting rod 302. When it is necessary to release the fixation, the threaded column is rotated in the opposite direction to separate the two movable locking blocks 304, so that the connecting rod 302 can be moved easily. This effectively improves the flexibility and reliability of adjusting the position of the connecting rod 302 during the use of the sander, thereby ensuring the accuracy of the sanding operation.

[0032] Working principle: The limiting spring 405 is sleeved on the outside of the through rod 404. When it is necessary to adjust the angle of the auxiliary grip component 30, the relevant personnel can pull the pull rod 406, which will drive the through rod 404 to move away from the rotating disk 401. At this time, the baffle 4041 compresses the limiting spring 405, and the other end of the through rod 404 disengages from the positioning hole 402. The rotating disk 401 is released from its fixed state. Subsequently, the relevant personnel can rotate the auxiliary grip component 30, and the rotating disk 401 rotates synchronously with the auxiliary grip component 30. After rotating to the required angle, the pull rod 406 is released, and the limiting spring 405, under the action of elastic restoring force, drives the through rod. Inserting 404 into the corresponding positioning hole 402 re-fixes the rotating disk 401, thereby completing the angle positioning of the auxiliary grip component 30. This structural design makes the angle adjustment operation convenient and efficient. Moreover, by setting multiple positioning holes 402, it can meet the diverse needs of the angle of the auxiliary grip component 30 in different working scenarios, further improving the flexibility and adaptability of the sander during use. It is worth noting that when the pull rod 406 is loosened, the through rod 404 will not be accurately inserted into the positioning hole 402. During the adjustment process, relevant personnel need to manually position the through rod 404 and the positioning hole 402. When the auxiliary grip component 30 is needed, the operator can rotate the movable locking blocks 304 to both sides to disengage it from the fixed slot 303. At this time, the connecting rod 302 is released from its fixed position, and the auxiliary grip rod 301 can be rotated downwards around the rotating disk 401. After the auxiliary grip rod 301 is rotated to the appropriate position, it can be fixed in place by cooperating with the angle limiting component 40. The auxiliary grip rod 301 allows the operator to select the gripping point according to actual needs, bringing convenience to the operator. In addition, when the auxiliary grip rod 301 is not in use, the operator can rotate the auxiliary grip rod 301 upwards and then lock it into the fixed slot 303 by the movable locking blocks 304 to fix the auxiliary grip rod 301 in place. This combination of folding and fixing structure not only saves storage space for the sander, but also allows for quick switching of the auxiliary grip component's usage state according to operational needs, enhancing the practicality of the equipment.
