Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of micro electric polisher, especially micro electric polisher handle structure. BACKGROUND

[0002] In many fields such as industrial manufacturing, hand DIY, micro electric polisher plays a very important role. Its handle structure is directly related to the operation experience and work efficiency of the user. With the continuous development of technology and the increasing demand for fine operation, higher standards are put forward for the design of micro electric polisher handle structure. An ideal handle structure not only ensures the comfort of the user's hand during long-term use, but also can adapt to different working scenes and operation requirements. Whether it is fine polishing in complex and narrow space or rapid processing on large area objects, the handle should give a stable and reliable holding feeling, and also has enough convenience in daily maintenance and cleaning, which prompts related technical personnel to continuously explore more optimized micro electric polisher handle structure design scheme.

[0003] The existing micro electric polisher handle usually adopts integrated molding design or simple bolt fixing method. The handle of integrated molding is closely connected with the main device and cannot be disassembled, which requires high mold precision and high cost in the production process. The handle fixed by bolts needs to use special tools such as wrench during installation and disassembly, which is more cumbersome. The length of the handle is generally fixed and cannot be flexibly adjusted according to the actual needs of the user and different use environment. And in the holding part, most of them only simply use rubber sleeve or rough surface treatment to increase friction and have limited anti-skid effect. In the case of long-term use or more sweating, the handle is still prone to slipping, which affects the normal operation of polishing.

[0004] The existing micro electric polisher handle structure has many inconveniences. For example, due to the fixed connection method of the handle and the main device, the handle cannot be disassembled and cleaned thoroughly when cleaning, and it often needs to be cleaned together with the main body, which not only increases the difficulty of cleaning, but also causes water or dust to enter the inside of the main body due to improper cleaning, affecting the service life and performance of the polisher. At the same time, during use, if the length of the handle is not suitable for the user or the current working scene, the user can only operate reluctantly because the length cannot be adjusted conveniently, which not only reduces the work efficiency, but also causes hand fatigue due to uncomfortable holding, and even causes polishing failure in some fine polishing operations, affecting the quality of the final product. Therefore, the micro electric polisher handle structure is proposed to solve the above problems. UTILITY MODEL CONTENTS

[0033] Specifically, when using the micro electric polisher, first, handle one 6 and handle two 7 are placed on the outer wall of the main device 1. Because the negative magnet 11 in handle two 7 and the positive magnet 10 in handle one 6 have mutual adsorption force, they will be tightly fixed on the main device 1, forming a complete handle structure. The user can put his fingers into the grip groove 4, which can make holding more convenient and comfortable. The anti-slip ball 3 in the grip groove 4 and the anti-slip groove 2 on the outer wall of the main device 1 can effectively increase the friction force to prevent the handle from slipping off during operation. After all preparations are completed, press the start button 8, and the polishing head 9 will rotate at high speed, thereby precisely polishing the target object, facilitating disassembly and assembly, and enhancing the anti-slip property.

[0034] Referring to Figure 1 , Figure 3 , and Figure 4 , the telescopic assembly includes a slide column 15, the outer wall of the slide column 15 is made of finely polished stainless steel material, has good smoothness and wear resistance, the outer wall of the slide column 15 is slidingly connected in the main device 1, one end of the slide column 15 is fixedly connected with the tail end 5, a sliding groove 14 is formed in the slide column 15, a rotating groove 13 is formed in the slide column 15, a clamping groove 12 is formed in the slide column 15, a limiting plate 17 is slidingly connected in the main device 1, the limiting plate 17 is made of lightweight aluminum alloy material, which reduces the weight of the overall structure while ensuring sufficient strength, and a high-precision sliding block is installed on the outer wall of the limiting plate 17, which tightly cooperates with the guide rail in the main device 1 to ensure that the limiting plate 17 is stable and does not shake during sliding, the outer wall of the limiting plate 17 is slidingly connected in the main device 1, a spring 18 is arranged in the main device 1, one end of the spring 18 is fixedly connected to the inner wall of the main device 1, the other end of the spring 18 is fixedly connected to the outer wall of the limiting plate 17, an arc-shaped clamping block 16 is fixedly connected to the bottom of the limiting plate 17, the arc-shaped clamping block 16 has a specially designed arc-shaped structure, the outer wall of the arc-shaped clamping block 16 is made of alloy steel material after quenching treatment, has high surface hardness and smoothness, and can flexibly and smoothly slide in the main device 1 and the clamping groove 12, the rotating groove 13 and the sliding groove 14, thereby realizing the clamping and unlocking functions during the length adjustment process of the handle, accurately adjusting the length of the micro electric polisher handle to meet the use requirements of different users in various working scenarios, the outer wall of the arc-shaped clamping block 16 is slidingly connected in the main device 1, the outer wall of the arc-shaped clamping block 16 is slidingly connected in the clamping groove 12, the outer wall of the arc-shaped clamping block 16 is slidingly connected in the rotating groove 13, and the outer wall of the arc-shaped clamping block 16 is slidingly connected in the sliding groove 14.

[0035] Specifically, when the length of the handle needs to be adjusted to adapt to different use requirements, the tail end 5 can be rotated. The rotation of the tail end 5 drives the synchronous rotation of the slide column 15 connected thereto. Since the arc-shaped clamping block 16 clamped with the clamping groove 12 is arc-shaped, the arc-shaped clamping block 16 is pushed upward during the rotation of the slide column 15. The upward movement of the arc-shaped clamping block 16 drives the sliding of the limiting plate 17 inside the main body device 1, and the spring 18 is compressed in this process. With the continuous movement of the arc-shaped clamping block 16, it gradually slides from inside the rotating groove 13 to inside the sliding groove 14. At this time, the tail end 5 can be pulled, and the tail end 5 drives the smooth sliding of the slide column 15 inside the main body device 1 until the appropriate length is reached. Then turn back the tail end 5, the arc-shaped clamping block 16 will slide from the rotating groove 13 back to the clamping groove 12 inside, at this time the compressed spring 18 rebounds, pushes the arc-shaped clamping block 16 back to the clamping groove 12, thereby realizing the fixation of the length of the handle, completing the entire length adjustment process, so that the micro electric polisher can better meet the operation requirements of different users in different working conditions.
