The present disclosure provides a cell group activation and deactivation indication method, system, terminal, network node and storage medium, wherein the method comprises: a terminal sends a cell group activation request or deactivation request to a network node of a network side according to service requirements; the bearer message of the cell group activation request or the cell group deactivation request comprises a MAC CE message; the terminal receives a cell group activation indication or deactivation indication sent by the network node, and performs an activation or deactivation operation corresponding to the cell group activation indication or the cell group deactivation indication; the bearer message of the cell group activation indication or the deactivation indication comprises a MAC CE message. The method, system, terminal, network node and medium of the present disclosure realize fast and flexible cell group activation or deactivation request and indication through MAC CE message in a multi-connection scenario, solve the problem that multiple cell groups cannot be activated or deactivated flexibly and quickly, and can utilize network resources more quickly and flexibly.

This utility model relates to the field of milling cutter technology and discloses a milling cutter with chamfering function, including a cutter handle and a milling cutter body. The top of the milling cutter body is clamped and installed in the bottom clamping structure of the cutter handle. A groove is formed on the surface of the milling cutter body. External thread structures are provided at both the top and bottom of the milling cutter body. An internal thread kit and a chamfering component are slidably installed in the groove and on the surface of the milling cutter body, respectively. The internal thread kit can apply pressure and limit the top of the chamfering component during the helical locking process with the external thread structure at the bottom of the milling cutter body. A positioning screw is installed between the bottom of the internal thread kit and the top of the chamfering component. This utility model forms a multi-functional chamfering structure through the chamfering component, positioning screw, and internal thread kit. After being used alternately with the two external thread structures set at the top and bottom of the milling cutter body, it can provide chamfering conditions for the edges and corners of the milled workpiece without interfering with the cutting use of the milling cutter body itself.

This utility model relates to the field of automotive bracket technology, and more particularly to a surface flatness control device for the demolding process of an automotive bracket mold. It includes: a worktable, a support frame on the worktable, a switching component on the top of the support frame, a mold component on one side of the bottom of the switching component, and a flattening demolding component on the side of the bottom of the switching component away from the mold component. By setting up the switching component, a motor drives a lead screw to rotate, enabling rapid switching between the upper mold and the mounting plate, thus improving the automation and operational efficiency of the demolding process. Furthermore, by setting up the flattening demolding component, the position of the brush can be adjusted by extending and retracting the telescopic rod of the telescopic cylinder five according to the size and specifications of the material. The brush can remove burrs and minor imperfections from the surface of the material during its ascent, improving the surface flatness of the material.
