With this use, processed object item the device which locks 1 of especially surface condition and 9 is explained, this has the installation aspect 2. The installation aspect 2 is formed elastically, possesses one retention device at least. The result of forming the installation aspect 2 elastically, the various processed object items to make 1 which possess the surface form which differs and 9 conform it is possible the device. Airtightness in order to seal, one or the plural retention devices, are actualized, as sphere 5 sphere 5 is kept in opening 6 where it is actualized with the form of the especially hole by elastic elastic surface condition section 8. Elastic surface condition section with 8 and the installation aspect 2, the presser bar pressure exists, the processed object item 1 which is installed on the installation aspect 2 by presser bar pressure or the pneumatics of the environment, and 9, is pushed vis-a-vis the installation aspect 2. Processed object item with consequence of weight of 1 and 9, sphere 5 is pushed out outside opening in only the territory of the installation aspect 11, when because of this, processed object item 1 and 9 has the groove 10 of the big area, as for the presser bar pressure, it is not possible and, to come out, it cannot flow the air from around environment. It is possible to lock with that device the processed object item 1 which possesses the groove 10 and 9, at the time of processing with the device which relates to this invention, various surface forms and.
