Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority to Chinese Patent Application No. 202423062711.X filed on Dec. 12, 2024, in China National Intellectual Property Administration, the contents of which are incorporated by reference herein. FIELD The subject matter herein generally relates to field of testing equipment technology, particularly to a sealing workpiece and a vacuum testing equipment. BACKGROUND In reliability testing, high altitude and vacuum testing are common test items, and both high altitude and vacuum testing can be performed in a piece of vacuum testing equipment. In some testing processes, the items to be tested need to be tested at high altitude or in a vacuum when the device is turned on. It is often necessary to connect the items to be tested in the vacuum testing equipment with a piece of peripheral equipment outside the vacuum testing equipment to obtain various test parameters of the items to be tested through the peripheral equipment. The vacuum testing equipment is usually provided with an external connection hole, and wires can be used to connect the items to be tested in the vacuum testing equipment with the peripheral equipment outside the vacuum testing equipment via the external connection hole. In order to improve the accuracy of the test, after the items to be tested are connected to the peripheral equipment, the external connection hole needs to be sealed. To seal the external connection hole, the method commonly used in the relevant technology is: using a sealing strip to seal the external connection hole, and then using specialized clay to fill and seal the wire located at the external connection hole. However, in the above described method, filling the clay or removing the clay cannot be completed in one go, which is time-consuming and labor-intensive. In addition, in some more stringent test environments, when the material strength of the clay is not enough to support the vacuum pressure, the clay often collapses and be sucked into the vacuum testing equipment, resulting in a vacuum leakage problem, which, in turn, affects the test efficiency of the items to be tested.
