The driving assembly is disposed pivotally on the toy gun and linked with a shaft to pivot by the action bar. The firing assembly has a pushing portion and a triggering portion disposed oppositely to the pushing portion. The triggering portion makes the firing assembly reciprocate by an elastic member. The shaft is disposed with a pushing surface. The pushing surface pushes the triggering portion of the firing assembly when the shaft rotates pivotally. ## Claims ### Claim 1 A pneumatic valve mechanism, disposed in a toy gun, the pneumatic valve mechanism comprising: a trigger, comprising an action bar; a driving assembly, disposed pivotally on the toy gun, and linked with a shaft to pivot by the action bar; and a firing assembly, comprising a pushing portion and a triggering portion disposed oppositely to the pushing portion, and the triggering portion configured to make the firing assembly move reciprocally by an elastic member; wherein the shaft comprises a pushing surface, and the pushing surface is configured to push the triggering portion of the firing assembly when the shaft rotates pivotally. ### Claim 2 (depends on 1) The pneumatic valve mechanism of claim 1, wherein the pushing surface is a bevel. ### Claim 3 (depends on 1) The pneumatic valve mechanism of claim 1, wherein the pushing surface is formed by inward denting from a cylindrical surface of the shaft. ### Claim 4 (depends on 3) The pneumatic valve mechanism of claim 3, wherein the firing assembly is pressed by the elastic member to make the pushing portion be flatly attached with the pushing surface. ### Claim 5 (depends on 1) The pneumatic valve mechanism of claim 1, wherein the driving assembly comprises a fork portion disposed protrusively thereon to be linked with the action bar. ### Claim 6 (depends on 5) The pneumatic valve mechanism of claim 5, wherein the action bar comprises a recess disposed concavely thereon, and the fork portion is configured to clamp the recess. ### Claim 7 A toy gun structure comprising: a launcher, comprising a barrel with a loading space; and a pneumatic valve mechanism, disposed behind the loading space of the barrel, and comprising a trigger, comprising an action bar; a driving assembly, disposed pivotally on the barrel, and linked with a shaft to pivot by the action bar; and a firing assembly, comprising a pushing portion and a triggering portion disposed oppositely to the pushing portion, and the triggering portion configured to make the firing assembly move reciprocally toward the loading space by an elastic member; wherein the shaft comprises a pushing surface, the pushing surface is configured to push the triggering portion of the firing assembly toward the loading space when the shaft rotates pivotally. ### Claim 8 (depends on 7) The toy gun structure of claim 7, wherein the barrel comprises an installing position located behind the loading space for the pneumatic valve mechanism to be disposed. ### Claim 9 (depends on 7) The toy gun structure of claim 7, wherein a latch is disposed on the barrel. ### Claim 10 (depends on 7) The toy gun structure of claim 7, wherein the pushing surface is a bevel. ### Claim 11 (depends on 7) The toy gun structure of claim 7, wherein the pushing surface is formed by inward denting from a cylindrical surface of the shaft. ### Claim 12 (depends on 11) The toy gun structure of claim 11, wherein the firing assembly is pressed by the elastic member to make the pushing portion be flatly attached with the pushing surface. ### Claim 13 (depends on 7) The toy gun structure of claim 7, wherein the driving assembly comprises a fork portion disposed protrusively thereon to be linked with the action bar. ### Claim 14 (depends on 13) The toy gun structure of claim 13, wherein the action bar comprises a recess disposed concavely thereon, and the fork portion is configured to clamp the recess.
