Description

Technical Field

[0001] This utility model relates to the field of hoe polishing fixture technology, specifically a hoe polishing fixture. Background Technology

[0002] The hoe is a traditional Chinese long-handled agricultural tool with a flat, thin, horizontally mounted blade. It can be used for harvesting, digging holes, ridging, tilling, covering soil, weeding, breaking up soil, cultivating, and hilling, making it a versatile tool and one of the most commonly used tools by farmers. During production, hoes need to be polished using a polishing machine.

[0003] However, the current clamps are not convenient for holding and fixing the hoe, and the operation is cumbersome and inconvenient to use. Utility Model Content

[0004] The present invention provides a hoe polishing clamp, which solves the problems of existing clamps being inconvenient to hold and fix the hoe, cumbersome operation, and inconvenient use.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A hoe polishing fixture includes a base with a bracket on the base. A first fixed plate is rotatably connected to the bracket. A movable component is mounted on the first fixed plate, and a fixed platform is mounted on the movable component. The fixed platform is linearly displaced by the movable component, and a tightening screw is rotatably connected to the fixed platform. The fixture also includes a second fixed plate threadedly connected to the tightening screw. The second fixed plate has two limiting members, and the first fixed plate has limiting grooves that mate with the limiting members. A support rod for supporting the hoe is mounted on the base. The position of the limiting grooves on the first fixed plate remains constant, but the position of the limiting members on the second fixed plate can be adjusted according to different hoe sizes to secure the hoe in conjunction with the limiting grooves. In use, the tightening screw is passed through the through hole on the hoe head for inserting the hoe handle. Then, a second fixing plate with a width corresponding to the width of the hoe is selected, and the second fixing plate is threadedly connected to the tightening screw, so that the limiting parts are located in the limiting groove. Then, by rotating the tightening screw, the second fixing plate is brought closer to the first fixing plate, thereby clamping the hoe located between the two. Then, the lower side of the hoe is supported by the support rod, and the upper side of the hoe is polished by the polishing device. After the upper side is polished, the first fixing plate is rotated so that the lower side of the hoe faces upward, and the support rod is used again for support, so that the lower side of the hoe is polished by the polishing device. At the same time, the position of the fixing platform on the first fixing plate can be adjusted by the moving component to accommodate hoes of different lengths. The structure of this application allows for the selection of a second fixing plate to accommodate the hoe to be processed, thereby clamping the hoe in conjunction with components such as the first fixing plate; it also allows for adjustment of the position of the fixing platform to accommodate hoes of different lengths and through holes in the hoe handle for polishing; and it allows for the use of a limiting member and a limiting groove to prevent the second fixing plate from rotating with the tightening screw, and to prevent the hoe from becoming misaligned during processing.

[0007] Furthermore, a through slot is formed on the first fixed plate. The moving component includes a guide rod fixedly connected to the through slot and an adjusting screw rotatably connected to the through slot. The adjusting screw is axially parallel to the guide rod, and its outer end extends beyond the first fixed plate. The fixed platform is threadedly connected to the adjusting screw and slidably connected to the guide rod. This structure allows the adjusting screw to be rotated, thereby cooperating with the guide rod to adjust the displacement of the fixed platform. The overall structure is simple, easy to use, and does not affect the installation of the tightening screw.

[0008] Furthermore, the limiting component is a limiting block, which is disposed on the second fixing plate. The limiting component using this structure is simple and practical.

[0009] Furthermore, a connecting block is provided at the lower end of the support rod, and two connecting slots are provided on the base to cooperate with the connecting block. The connecting block is inserted into either of the connecting slots. In use, the connecting block can be inserted into the connecting slot to achieve fixation, and different connecting slots can be replaced to support the rotating hoe.

[0010] Furthermore, the support rod is a telescopic rod. This structure allows for length adjustment to accommodate different hoes.

[0011] Beneficial effects: The structure of this application allows for the selection of a second fixing plate based on the type of hoe to be processed, thereby clamping the hoe in conjunction with components such as the first fixing plate; it also allows for adjustment of the position of the fixing platform to accommodate hoes of different lengths and through holes in the hoe handle for polishing; and it allows for the use of a limiting member and a limiting groove to prevent the second fixing plate from rotating with the tightening screw, and to prevent the hoe from becoming misaligned during processing.
