Abstract: This invention discloses a power cable installation device, including a cart frame and an installation frame on the cart frame. An accommodation cavity is disposed at the bottom end face of the installation frame. The accommodation cavity is slidingly connected with a sliding base. Coordinated with the first elastic recovery device and the second elastic recovery device which are interconnected with opposite sides of the accommodation cavity, the sliding base will be more stable when sliding up and down. Meanwhile, with the locking and unlocking between a locking component in the first elastic recovery device and the second guide block, the sliding base will be more stable during the transportation of the cart frame. Thus, automatic control of transmission and driving of digging and drilling work can be achieved.

Abstract: The present invention provides a method for processing a shared file and a cloud storage server. The method comprises: receiving, by a cloud storage server, an update request message from a second client; determining that a first file is located within a storage region of a first client according to an identifier of the first file and acquiring current version information of the first file from the storage region of the first client; and if it is determined that the version of the first file on the second client is older than the version of the first file within the storage region of the first client, generating a first download address and transmitting the first download address to the second client, so that the second client downloads the first file in the current version. According to an embodiment of the present invention, it is able to synchronously update the shared file.
