The utility model discloses a medium-voltage circuit breaker handcart execution unit box with a locking mechanism, which is used on an electric execution mechanism of a medium-voltage circuit breaker handcart and comprises a box body, an execution mechanism and the locking mechanism. The box body is provided with a box door; the executing mechanism comprises a motor and a driving assembly, and the driving assembly is provided with a manual connecting part; the locking mechanism comprises a baffle assembly, a buckling block and a travel switch assembly. According to the utility model, the manual connection part is used for being connected with an external crank to realize manual operation, and the external hanging mechanism of the medium-voltage circuit breaker handcart can be ensured to be normally used in combination with electric driving realized by the motor; the baffle assembly is arranged and used for controlling the travel switch assembly to conduct electrical action and controlling the manual connecting part to conduct closing or opening action. Through the cooperation of the clamping groove and the clamping block, an execution mechanism for opening the box door for misoperation is prevented from violating five-prevention, and the use safety is improved.

This invention relates to a log management method and a log management system. Embodiments for reliable, safety-critical system logs are disclosed. In one embodiment, a method includes: obtaining data to be added to a log; creating entries for the data; and adding the entries to a linked sequence of entries in the log, wherein the linked sequence of entries includes a plurality of data entries and a plurality of sentinels intertwined with the plurality of data entries, wherein each data entry in the entry chain is appended to an error detection code calculated for that entry and a previously calculated error detection code or error detection root of the preceding data entry, and each sentinel in the entry chain includes an error detection code calculated for that sentinel and a previously calculated error detection code or error detection root of the preceding data entry, and each sentinel includes a previously calculated and encrypted blockchain value or blockchain root value of the preceding sentinel.

The utility model relates to the technical field of combined machine tools, in particular to a two-way expanding tool bit of a combined machine tool. The body flange is a main body structure of the expanding tool bit; the movable gear shaft penetrates through the body flange and is meshed with the left side helical teeth and the right side helical teeth; the left moving block is fixedly connected with the left helical tooth, and the right moving block is fixedly connected with the right helical tooth; the middle pressing plate, the right pressing plate and the left pressing plate press the left moving block and the right moving block on the body flange through bolts; the left side helical teeth and the right side helical teeth are bidirectional asymmetric helical racks, the left moving block and the right moving block are driven to move independently in two directions through axial movement of the moving gear shaft, and multi-procedure machining is completed through one-time feeding. The utility model provides the combined machine tool expanding tool bit which is compact in structure, zero in transmission clearance and capable of supporting two-way synchronous or asynchronous machining, the problems of low efficiency, poor precision, insufficient reliability and the like of traditional equipment are fundamentally solved, and technical guarantee is provided for machining of high-precision complex parts.
