[0023] The structure of the vacuum chuck of the embodiment is shown in the drawing as Figs. 1 to 3 The handle assembly 2 is located at the top of the base 1, and one end of the handle assembly 2 is provided with the vacuumizing device 4, and the other end of the handle assembly 2 is provided with the battery pack 5. The sealing ring 3 is located at the bottom of the base 1, and the sealing ring 3 defines a sealed space in the inner periphery of the sealing ring 3. The battery pack 5 is used to power the vacuumizing device 4, and the vacuumizing device 4 is responsible for extracting air from the sealed space to achieve the effect of vacuum adsorption.

[0024] The handle assembly 2 includes the first handle 6 and the second handle 7, the first handle 6 and the second handle 7 form an inverted U-shaped type, the vacuumizing device 4 is located in the first handle 6, the battery pack 5 is detachably connected with the second handle 7, the second handle 7 includes two battery seats 8, the two battery seats 8 are symmetrically spliced and are in butt joint with the first handle 6 to form an installation structure for installing the battery pack 5, and the battery pack 5 is detachably installed on the installation structure formed by the two battery seats 8 in an upper and lower plug-in manner. This divides the handle assembly 2 into two parts, the first handle 6 is used to accommodate the vacuumizing device 4, and the second handle 7 is used to install the battery pack 5. Moreover, the second handle 7 is composed of two symmetrical battery seats 8, the two battery seats 8 can be spliced together and butt joint with the first handle 6 to form a complete and fully functional installation structure, so that the user can conveniently replace the second handle 7, i.e. the battery seat 8 part without disassembling the first handle 6, which not only simplifies the replacement process of the battery seat 8, but also greatly improves the compatibility of the vacuum chuck for different models and capacity battery packs, so that the product is more flexible and the application scenarios are more extensive.

[0025] In order to ensure the stable connection between the handle assembly 2 and the base 1, a first mounting slot 9 and a second mounting slot 10 are respectively arranged at the two ends of the top of the base 1. When the first handle 6 and the second handle 7 are butted, the first handle 6 and the second handle 7 will be respectively inserted into the corresponding first mounting slot 9 and the second mounting slot 10. Specifically, the first handle 6 comprises an upper cover 11 and a lower cover 12, the lower cover 12 is inserted into the first mounting slot 9 and connected with the base 1, and the upper cover 11 is located above the lower cover 12 and encloses the lower cover 12 to form a containing cavity for accommodating the vacuumizing device 4.
