A counterforce-counteracting device for a nailer comprises an active device, a rotating member, and a weight device. The active device drives the rotating member and the weight device to move. After the active device moves, the weight device is driven by the rotating member to produce a counterforce, so as to counteract the counterforce of the nailer. Thereby, such a device is secure and is easy to assemble.

What is claimed is: 1. A counterforce-counteracting device for a nailer, comprising: an active device disposed in the nailer and including an active member and at least one first driving member, the first driving member being located at one side of the active member; a rotating member pivotally disposed in the nailer and moved by the first driving member of the active member; a weight device disposed in the nailer and including a weight member and at least one second driving member, the second driving member being located at one surface of the weight member facing the rotating member and driven by the rotating member; when the active device being moving, the first driving member of the active member driving the rotating member to move, and then the rotating member moving the second driving member of the weight member of the weight device, enabling the active device and the weight device to produce a counterforce, and the weight device being used to produce a counterforce to counteract a counterforce produced by the active device. 2. The counterforce-counteracting device for a nailer as claimed in claim 1, wherein the active device includes the active member, a nail-hitting member, a first elastic member, and two first driving members, the active member is disposed in the nailer, the nail-hitting member is located at one end of the active member close to a muzzle of the nailer and is provided for hitting the nail into a work piece, an other end of the active member is formed with a containing portion for receiving one end of the first elastic member, an other end of the first elastic member is abutted against an inside of the nailer, the first driving members are located at one end of the active member facing the rotating member, each first driving member is formed with a first driving portion serves to drive the rotating member to move. 3. The counterforce-counteracting device for a nailer as claimed in claim 1, wherein the rotating member includes a pivot member and at least one engaging portion, the pivot member is inserted into the rotating member from one side of the nailer, the rotating member is rotated around the pivot member, the engaging portion is rotated by the first driving portion of the first driving member of the active member and then drives the weight device to move. 4. The counterforce-counteracting device for a nailer as claimed in claim 1, wherein the weight device includes the weight member and two second driving members, the weight member is disposed in one end of the nailer close to the rotating member, the second driving member is located at one side of the weight member close to the rotating member, each second driving member is formed with a second driving portion for engaging with the engaging portion of the rotating member. 5. The counterforce-counteracting device for a nailer as claimed in claim 1, wherein an buffer member is disposed in one end of the nailer close to the active device and is abutted against the weight member, the buffer member is made of flexible material that can absorb shock and stress, such as soft pad, plastic, rubber, and cork. 6. The counterforce-counteracting device for a nailer as claimed in claim 1, wherein one end of the first driving member of the active member of the active device is defined with a first positioning portion, one end of the weight member of the weight device is defined with a second positioning portion diagonally opposite the first positioning portion, the first positioning portion of the first driving member of the active member and the second positioning portion of the weight member are provided for fixing a pulling member, the pulling member winds around a containing portion formed in the rotating member, the active device cooperates with the weight device to drive the pulling member to move, enabling the pulling member to extend and retract, such that the active device and the weight device are used to produce a counterforce. 7. The counterforce-counteracting device for a nailer as claimed in claim 1, wherein one end of the weight member of the weight device is formed with a containing portion for receiving one end of a second elastic member, and an other end of the second elastic member is abutted against an inside of the nailer.
