Abstract: The method for sending the trunking paging includes: after receiving a group paging request, a base station sending a paging message to trunking terminals in a present cell in a predetermined paging time slot, wherein the paging message includes a group identification of a group needing to be paged. A base station for sending the trunking paging includes a receiving module and a sending module. A method for receiving the trunking paging includes: after monitoring a paging message, when determining that a group identity included in the paging message is the same as a group identity of the group to which the present terminal belongs, a trunking terminal accessing the group service, and sending a paging response to base station, or not sending a paging response to base station. A trunking terminal for receiving the trunking paging includes a monitoring module, a judging module and a group service processing module.

Abstract: A chain saw includes a housing, a sprocket wheel which is provided in the housing for driving a saw chain, and a chain guide for guiding the movement of the saw chain. The chain guide extends out longitudinally from the housing and is movable longitudinally relative to the housing. The chain saw includes a chain tensioning device. The chain tensioning device comprises a driven member arranged on the chain guide, a driving member which drives the driven member to move the chain guide longitudinally, a rotating device rotating the driving member, a clutch device arranged between the rotating device and the driving member, and an elastic component which is disposed between the rotating device and the clutch device. The chain tensioning device presses the chain guide while it tensioning the saw chain. Thus it prevents effectively the chain guide from loosing after the saw chain is tensioned.
