Abstract: An apparatus, having a server and processor, is configured to receive a first set of security rules applicable to a set of users or a set of files for a first period of time. The first set of security rules are executable in an order of priority. The processor receives an interim security policy that is different from the first set of security rules. The interim security policy is applicable to a subset of the set of users for a second period of time that is less than the first period, or a subset of the set of files for a second period of time that is less than the first period. The processor determines, in the first set of security rules, an insertion point among the order of priority. The processor executes, at the insertion point and in the first set of security rules, the interim security policy.

Abstract: A multi-functional bench vice with a quick-change jaw includes a movable vice body, a fixed vice body, a screw rod, and a handle. The fixed vice body is provided with a fixed jaw. A quick-change assembly and a movable jaw assembly are installed on the movable vice body. The quick-change assembly includes an adjustment rod and a pull rod. The adjustment rod is installed on the movable vice body through an external thread, and is connected to one end of the pull rod through the internal thread. The helical direction of the external thread is opposite to the helical direction of the internal thread. The other end of the pull rod passes through the movable vice body and is clamped on the movable jaw assembly. The movable jaw assembly corresponds to the fixed jaw.

Abstract: A bench vice includes a fixed vice body, a movable vice body, a screw rod, a screw nut, a quick-action mechanism, and an operating handle. The quick-action mechanism controls the screw rod and screw nut to engage or disengage so as to move slowly or quickly. The operating handle operates the quick-action mechanism. The movable vice body is assembled with the screw rod into an assembly, and both the quick-action mechanism and the operating handle are arranged on the front end of the fixed vice body. Since the quick-action mechanism and the operating handle are arranged on the front end of the fixed vice body, the operator can operate more conveniently, and thereby the working efficiency is improved.
