[0023] The technical solution of the present invention will be described below in conjunction with the accompanying drawings of the present invention.

[0024] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of the present utility model, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0025] The utility model provides a hand-held staggered-layer grinding device. In the prior art, when performing the staggered-layer grinding process, the maintenance worker is sent to the maintenance area by a hanging basket, and then the grinding is performed with a hand-held angle grinder. This operation process has a high risk factor and poor operation convenience. In order to solve the above technical problems, the utility model optimizes the hand-held staggered-layer grinding device to achieve the purpose of improving the convenience of operation and reducing the risk factor.

[0026] Please see Figures 1 to 6 The utility model provides a handheld staggered-layer grinding device, comprising a folding bracket 10 in a hollow rectangular shape, and a first slide groove 111 is provided on the top of the folding bracket 10, and a sliding rod 20 is slidably matched on the first slide groove 111, and a second slide groove 21 is provided on the side of the sliding rod 20, and an engraving machine 22 is slidably matched in the second slide groove 21. As shown in the figure, the first slide groove 111 is perpendicular to the cross section where the groove direction of the second slide groove 21 is located. Under the interaction of the first slide groove 111 and the second slide groove 21, the engraving machine 22 can move in multiple directions in the hollow rectangular folding bracket 10, so that it can grind different parts.

[0027] The engraving machine 22 is specifically installed by providing a slider 23 in the second slide groove 21, and providing a mounting ring 24 at the free end of the slider 23. The engraving machine 22 is installed in the mounting ring 24. In order to facilitate the up and down movement of the engraving machine 22, an adjusting spring 25 is also sleeved between the mounting ring 24 and the outer wall of the engraving machine 22, as shown in the figure.

[0028] The engraving machine 22 operates through the tool at the bottom, so that it can ensure that the materials to be processed are taken away efficiently and easily. In addition, an adjusting sleeve 26 is provided on the outside of the engraving machine 22, which is specifically arranged on the outside of the tool to adjust the protruding height of the tool, thereby achieving more precise milling work. Specifically, the adjusting sleeve 26 is connected to the engraving machine 22 by threaded cooperation, so that the purpose of adjustment can be achieved.

[0029] In order to make the grinding equipment adaptable to the working environment, the folding bracket 10 is further optimized. Specifically, the folding bracket 10 includes a support rod 11 and a connecting rod 12. The support rod 11 and the connecting rod 12 are connected end to end by a hinge 13 to form a hollow rectangular frame structure. As shown in the figure, the support rod 11 has two, which are arranged opposite to each other. The first slide groove 111 is opened at the top of the support rod 11, so that the sliding rod 20 can slide on the support rod 11. In this embodiment, the connecting rod 12 is composed of two support rods, and the adjacent support rods are connected by a hinge 13, so that the folding bracket 10 can be folded in half to achieve the purpose of easy storage. As shown in the figure, in addition, vacuum suction cups 14 are arranged at the bottom of the four corners of the folding bracket 10, and the handheld staggered grinding equipment is fixed to the surface of the blade by the vacuum suction cups 14, so that the operator does not need to rely on manpower to maintain the weight of the workpiece during use, thereby reducing the work intensity.

[0030] The workflow of this utility model is as follows:

[0031] After opening the connecting rod 12 of the folding bracket 10, so that the folding bracket 10 forms a hollow rectangular structure, the folding bracket 10 is fixed to the surface of the area to be processed by the vacuum suction cup 14. After fixing, the sliding rod 20 is installed in the first slide groove 111 by means of bolts or fixings, and then the engraving machine 22 with the adjusting sleeve 26 is installed in the mounting ring 24 so that it can move in the second slide groove 21. Under the action of the adjusting sleeve 26, the tool extension height of the engraving machine 22 can be adjusted. After the overall installation is completed, the operator only needs to hold the upper end of the engraving machine 22, press the engraving machine 22 to make it fit the surface of the blade, and then move it relatively through the second slide groove 21 to achieve the purpose of moving along the shape required by oneself.

[0032] The handheld staggered-layer grinding equipment provided by the utility model is equipped with a vacuum suction cup 14 on the folding bracket 10, so that the whole equipment can be fixed in the area to be ground, which simplifies the operation of the operator to fix the equipment and improves the convenience and safety of operation. By arranging a first slide groove 111 on the folding bracket 10 and a second slide groove 21 on the sliding rod 20, the engraving machine 22 can be moved in the hollow area of ​​the folding bracket 10, and then the corresponding grinding area can be locked, thereby improving the grinding efficiency.

[0033] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
