INSTRUCTIONS OF THE INVENTION: Technical Field of the Invention The present invention relates to an improvement of a safety lighter, which is characterized in that the fire cover is provided with an extension portion, so that the gear teeth and/or the grinding wheel combined with the grinding wheel are compulsively resisted. Stop the lighter safety protection structure that avoids the easy rotation of the grinding wheel combination of the young children. [Prior Art] The easy-to-use lighter brings convenience and cost reduction to consumers. It can be said that it has been used for thousands of years but in modern times. The biggest breakthrough, but it also has a big worry in safety. The earlier structure is shown in Figure 1, including: a body 1 〇〇, a top cover 200, a grinding wheel 300, a fire cover 4 〇〇 The body 1 is a hollow body filled with liquid gas, and the closed portion fixed on the body is provided with a fire mouth 1〇〇1 having a neck portion 1002, and a top cover 2〇〇 is correspondingly disposed. Above the body 1〇〇, and extending two grinding wheel seats 2001, the two grinding wheel seats 2〇〇1 are each provided with a hole 20011, and an inner hole t has a toothed adjusting wheel 2004 correspondingly disposed on the base of the fire mouth looi , a press plate 2003 use set The portion 20031 is set in the hole 20012 at the bottom of the grinding wheel holder 20011, a spring yellow 3002 and a flint 3001 are placed in the fixing seat 2002, and the convex shaft 3000 of the grinding wheel 300 is then placed corresponding to the hole 20011 of the grinding wheel holder 2001, and then the fire cover 400 is placed. Set on the outermost part, it forms the most widely used simple lighter. However, because it is extremely easy to ignite, children in general are often in danger of being out of control due to the lack of crisis. 4 200844373 Subsequently, lighters with various safety structure designs appeared. As shown in Figure 2, the main structure is the same as that shown in Figure 1. It will not be repeated here. The difference lies in the cover. 200 - a through hole 20012 is disposed on the side, a safety tip 2004 is inserted into the top cover 200 from the through hole 20012, and a spring 20013 is disposed under the extension portion 20041 of the safety tip 2004, and the front end of the safety tip 2004 is provided with a hook In the rear part of 20042, a convex portion 20043 is provided, and a front end of the pressing plate 2003 is provided with a top portion 20032 (please refer to the drawing of FIG. 3A to FIG. 3C), and a flange 20031 is provided at the rear end, (' generally as shown in FIG. 3A The upper plane of the rear section of the aforementioned safety tip 2004 is a flange 20031 that abuts against the rear section of the aforementioned pressure plate 2003. The other pressure plate 2003 cannot pull the neck 1〇〇2 of the burner 1001 by the principle of lever to open the gas discharge, and The adjustment wheel 20041 is used to adjust the amount of gas discharge. If the safety tip 2〇〇4 is pushed from the right to the left horizontal direction (as shown in FIG. 3B), the flange 20031 below the pressure plate 2〇〇3, Ik is off the plane of the female full-length extension 20041 Therefore, the pressure plate 2〇〇3 can be easily pressed down by pressing the plate 2〇〇3 to open the gas discharge of the burner as shown in Fig. 3C, and after the force of the field release plate 2003, the safety tip 2〇〇 4 Because the spring force of the spring 20013 is instantaneously exited to the right side, the abutting top surface 2 of the thin front end of the pressing plate and the hook portion 20042 at the front end of the safety tip 2004 are also hooked and positioned to restore the protective structure against the action of the pressing plate 2003. The figure is a three-dimensional exploded view of the lighter structure after re-improvement, please refer to the 5A to 5B drawings. The main structure is similar to that of the earlier lighter. The difference lies in the use of the structure of the grinding wheel 300 to fix the grinding wheel 300. The shaft 3000 is slightly 200844373. The long three-piece safety wheel 3003 whose outer diameter is larger than the largest outer diameter of the grinding wheel 300 is set to have a convex axis. When used, the young child's fingers cannot be pressed with a large force. Therefore, most of the safety wheel 3003 with a large outer diameter can only be rotated, and the grinding wheel cannot be smoothly rotated to make the friction with the flint to form another safe lighter. Then there is a product of the invention patent No. 6676445B2.
