Abstract

This invention relates to an improved structure of a stapling gun. The stapling gun comprises a housing; a driving assembly; a transmission assembly; a control assembly and an impacting assembly. The driving assembly includes a power source and at least two power switches. The power source may be a regular electrical main power source or a rechargeable battery. The transmission assembly includes a motor, a transmission gear set and an operation gear that is driven by the on/off state of the driving assembly. The driven gear is merely formed with partial gear crowns. The control assembly includes at least two push buttons, a pressing member and a lock-thrusting piece. The two push buttons operates the driving assembly and transmission assembly upon being pressed, at which time, the pressing member is urged outwards by the lock-thrusting piece. The impacting assembly includes at least one impacting cylinder, a striking plate and a resilient member. The resilient member is provided in the impacting cylinder so as to cause the striking plate to push and strike the stapler cartridge outwards upon its relaxation. The impacting cylinder is driven by the working gear crowns of the operation gear. As such, when power is on, the impacting cylinder would strike forwards to push out the stapler cartridge when the working gear crowns no longer engage the impacting cylinder due to retraction of the impacting cylinder caused by the operation gear. The pressing member may be urged by a pushrod of the operation gear so as to disengage from the lock-thrusting piece thereby returning to its original position and turning off the power. Then one of the press buttons is released to cause the lock-thrusting piece to return to the engagement position with the pressing member. This invention provides a stapling gun structure that can be easily implemented and is of a simple and inventive construction.

Description

1243738 V. Description of the invention (1) [The invention of the invention belongs to the action of dividing the number of teeth in time to return the impact, resulting in [prior art] In the face of the current heterogeneous technology, there is no technical field, and the nail gun is an example. The functions of various industries require the source of power of the gun. Its equipment must be fired, so it is inconvenient in the surroundings, especially it can be used in air pressure chambers. It is new, streamlined, and powerful to win. [Content of the Invention] Good, especially A nail gun structure that reaches the retracting of the impact barrel, the power assembly, and the control assembly by the part. [Technical Field] Refers to a new structure of nailing gears that smashes into a structure to streamline the structure of the market. It does not endeavor to manufacture the knots in a timely manner, and the structural ideas are almost all required. Air equipment is required to change the construction site. Wait for the equipment here to find new opportunities to improve the user. Whether the structure of the gun is changed or not, the design, and the efficiency increase are intense, and various research and development, the structure can be said to be the first organization in the market, but the most dynamic way, the compressor and the air are many, and when construction, Moreover, the lack of a market for nail guns to change makes the industrial technology of the industry hope to break through. Therefore, the lack of extremely many types lies in that it is almost impossible to connect the power production gas pipeline to use it in ordinary households. In the competition, the effectiveness is improved, and the new moon has a customary product, and each has its current use of pneumatic squares to nail the carrying of Naibu-cho in general homes have created and increased their competition. The inventor felt this, and set out to make breakthroughs and innovations. Therefore, he considered that the pneumatic method of the user must be changed to an electric method, and it is best to use a wireless electric method to increase its use and portability. Convenience; therefore, the main technical structure of the present invention provides a new structure
