[0013] (III) Beneficial Effects

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. Since the connecting rod and vertical beam have a certain length, when the clamping plate and liner hold the high-temperature workpiece, there is still a certain distance between the robot or palletizer and the high-temperature workpiece and heating device. This allows the robot or palletizer to stay away from the high-temperature heat source, thus protecting the automated equipment and preventing related parts from aging due to high temperatures. This reduces the frequency of maintenance or replacement of related parts of the automated equipment under this working condition, ensuring the service life of the automated equipment and reducing the increase in later operating costs to a certain extent. This makes later use more worry-free and labor-saving. Moreover, the fixture has a simple structure, is easy to manufacture and maintain, has low production costs, and can achieve fast and accurate clamping while being stable and reliable. Therefore, it can ensure the safe and orderly transfer of high-temperature workpieces. Attached Figure Description
