[0017] The present application provides a telescopic variable distance clamping tool.

[0018] 1. This invention uses a first cylinder to push a fixed block, which in turn pushes a connecting frame connected to the fixed block forward. The movement of the connecting frame then drives the telescopic frame to extend forward, thereby causing each first clamping block connected to its joint point to move forward. Since each extension part of the telescopic frame moves by the same distance, the first clamping blocks connected to its joint points can move at equal distances. Combined with the telescopic movement of the first cylinder and the stable sliding forward movement of the first clamping blocks on the connecting rods on both sides, this invention achieves equidistant telescopic movement and variable-distance clamping adjustment between multiple clamping blocks. This enables rapid clamping and loosening of multiple workpieces and allows for simultaneous processing, effectively improving production efficiency.

[0019] 2. This invention uses a second motor to drive a fixed rod to rotate, which in turn drives a connecting flip plate to rotate horizontally, so that its reverse side faces upward and its bottom structure is aligned. Then, a first electric telescopic rod raises and lowers the bottom panel until its height is level with the height of the clamping blocks in the clamping mechanism. The first motor then drives a threaded rod to rotate, using the force of the threaded rotation as a driving force to move a connecting rod. This moving rod, in turn, causes multiple connected second clamping blocks to move at equal distances, aligning them with the equidistant distribution of the first clamping blocks in the clamping mechanism. This expands the clamping work line, allowing for the clamping of more workpieces. It can effectively adjust the production line by increasing or decreasing it according to actual production needs, thereby improving the efficiency of processing operations.

[0020] 3. This invention uses a handheld vacuum cleaner to manually remove processing waste. When a clamping mechanism is used for clamping operations and then the clamping expansion mechanism is activated, processing waste will fall onto a fixed frame. As the fixed frame moves, the waste will fall downwards and onto a slanted slide. Through its sliding action, the waste will slide into a waste box, where the vacuum head and transfer pipe will absorb the processing waste and store it in a vacuum cleaner. This facilitates the removal and processing of processing waste and ensures the cleanliness of the tooling. Attached Figure Description

[0036] By utilizing the clamping mechanism 2, the telescopic variable-distance clamping of the clamping fixture is achieved. In conjunction with the extension mechanism 4, the clamping expansion mechanism 3 is moved out, which can effectively extend the processing line and improve the efficiency of processing operations. Furthermore, by utilizing the cleaning mechanism 5, the processing waste is effectively cleaned up, ensuring the cleanliness of the equipment and the stability of the processing operation.

[0037] refer to Figures 4-5 The clamping mechanism 2 includes a placement plate 201. Vertical plates 202 are fixedly connected to the top left and right sides of the placement plate 201.

The movement of the connecting frame 209 then drives the connected telescopic frame 210 to extend forward, which in turn drives each of the first clamping blocks 206 connected to its joint points to move forward. Since the movement of each extension part of the telescopic frame 210 is basically the same, the first clamping blocks 206 connected to its joint points can move at equal distances and adjust pitch in coordination with the telescopic movement of the first cylinder 203. At the same time, the first clamping blocks 206 in the moving state slide forward on the connecting rods 205 on both sides, which makes them more stable.
