Abstract:
1. A trigger structure for switching one shoot mode or repeat shoot mode comprising: a trigger member, a top of the trigger member pivoted on a nail gun, a receiving space defined in the trigger member and extending to a bottom of the trigger member, a recess laterally defined on the trigger member, the trigger member having a first pivotal hole defined laterally and opposed to the recess, the trigger member having a second pivotal hole defined therethrough, the first pivotal hole and the second pivotal hole communicated with the receiving space, two protrusions extended from two opposite inner corners of the recess; and a switching member assembled into the receiving space, the switching member further comprising: a pivotal member having two pivotal portions at one end thereof, a connecting hole defined at another end of the pivotal member and corresponding to the first pivotal hole; an adjusting member being assembled to the trigger member by passing through the recess, the first pivotal hole and the connecting hole, a spring placed on the adjusting member and located between the pivotal member and the trigger member; and a trigger plate having a pivotal protrusion which is received between the two pivotal portions, a fixing rod passing through the second pivotal hole, the two pivotal portions and the pivotal protrusion; thereby when the adjusting member is received into the recess, the trigger plate is at a first position so that the trigger structure is under the repeat shoot mode; when the adjusting member is pushed from the first pivotal hole to the recess, the adjusting member is moved out of the recess and the adjusting member drives the pivotal member and the trigger plate to axially move along the fixing rod simultaneously; thereafter the adjusting member is rotated until the adjusting member is above the two protrusions; after the spring is recovering, the adjusting member is abutted against the two protrusions and the trigger plate is also positioned at a second position so that the trigger structure is under the one shoot mode.
