[Prior technology] Power tools are widely used in construction, machinery, electric power, petrochemical, metallurgy, transportation, agriculture and other industries. At the same time, because of their own hands-on (10), d〇 is a trend, so power tools have become a family 5\771t (4), for example, (4) Patent Announcement Vehicle, Zhangmu, Wuguo Patent Announcement No. 5, 738, 469, US Patent, ..., 5 Wei, and Taiwan: Taiwan No. 271 1281. For example, the power tools such as electric drills are roughly used for impact drills, hammer drills, etc., where the impact drill should be the most “two-acting tool. As the name suggests, the impact drill is applied for two people: for the hammer The function of Ua Zhannuan ringWt(10)) is similar to that of a general electric drill. It has the same design before the change. The user can attach the screw to the current or the grinding tool according to different needs. The screwdriver, the drill bit, and the second hitting drill generally have a lock screw groove, an electric drill slot, and a punching k-impact. The drill will determine the heart according to the torque setting of the screw groove. At this time, the impact drill rotates the motor continuously, but the screw is flat ^^ the skip wheel ^ High torque. When using electric drill, the rotary motor and the 5 M343562 front-end drill keep the same action all the time, output the maximum torque, and maintain the non-jump. When using the impact file, in addition to retaining the original electric drill function, it will start the shock at the same time. The mechanism provides impacts such as hoes and can be used to drill holes more efficiently, such as cement walls or other hard objects. In order to operate and adjust according to different needs. The impact conversion structure is usually designed between the rotating motor and the front end fitting to achieve the mechanical adjustment of the operation, and provides a user to set the control interface of the impact drill. For example, the first to third figures are conventional shock conversion. Structure φ As shown in Figure la, a single-cup impact conversion structure is designed. The output spindle 20 is threaded with a torque cup 2 2 ' and one end is exposed to the torque cup 2 2 for mounting the front end fitting (not The other end can be connected to a motor (not shown). The torsion cup 22 can be used to adjust the function of the impact drill. It has a slot mark 2 2 2 for indicating the screw groove and the torque setting. The stronger the large torque, the electric drill position indication portion 2222 indicates the position of the electric drill position, and the impact position indication portion 2224 indicates the position of the impact position. If the electric drill or the impact position is to be activated, the torque cup 22 must be clockwise (forward), for example. 10 Rotate to switch from the lowest torque screw to the drill or impact file. t - As shown in Figure lb, this conventional impact conversion structure is transmitted through the drive gear 242, planet gear 244, planet The planetary gear train 24 composed of the gear base 246 and the internal gear 248 transmits rotational power to the output spindle 20, and in addition to using the reduction ratio to increase the torque, the motor can be kept rotated and the output spindle 20 can be kept stationary. This is the so-called screw-gear function. This prior art technique utilizes the rotation of the torsion cup 22 to adjust the height of the screw 26 relative to the spacer 28 through the thread inside the torsion cup 22, M343562 = this 'sorghum compression spring 23, and then through the gasket force 1 in the steel ball 21 and then forced to 趴 趴 〇 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内The purpose of the force control (or called the jump control). In addition, the adjustment screw 9 p + tired, , 糸 26 and the spacer 28 maintain a space: the space of the steel ball 21, when the wheel When the main shaft 2〇 is subjected to the resistance of the second wire operation), the internal gear 248 will start to rotate and the bevel will lift the steel ball 21 up, so that the internal gear 24δ is opened steel = the output shaft 20 is captured 4 L,疋• or the control of the impact file without skipping the file’ As for the height of the electric drill file #塾片28, Hi can also be found by changing the adjusting screw. This kind of conventional technology cannot be directly switched from the lowest torque screw to the electric drill file or the impact groove. ,,, Μ also, after using the electric drill file or punching ^ α to switch to the screw file, must be from the electric drill file or impact; ^ 1 ± S screw file, can not directly return from the electric drill 'Tianzhu back to this from the use If you want to frequency (four) back to the screw slot. Slots, or impact grooves, must be ugly every time. It is inconvenient to use screw slots and electric drills. The mother turned the torque cup to nearly 360 degrees. At the same time, this conventional technique simply uses the jump control of the rotating torsion screw 26. It is difficult to clear the boundary ☆ Κ adjust the position of the electric drill file and continue to Twist:::: = : Threading: Torque screwing 'often provides the most than the general locking screw. Moreover, when applying this technique, in the screw groove 42, the change can not provide a significant step-type torque change, plus [ The book turns the steel ball 21 to raise the space 'user must rotate: Torque: the second two: reach the reduction 2 2 push the adjustment screw 7 M343562 = the end of the ,, at this time the dust-shrink spring 23 accumulated a very large elastic car ^The force cup 22 becomes very difficult. Force, the company ^ shows the double-cup impact conversion structure, there are two separately controlled torsion cups 42 and ", on: the main conversion between the gears, the lower layer of the cup" force adjustment. The third picture is also a kind of double cup: the number of the smashing floor is changed with the number of the single cup, and the yoke is made to make the same torque # 2 force, and the sliding push 62 can directly change the different slots.糸 “The two types of technology are required to be used on the same day in the use of the screw broadcast: two control interfaces, one set screw file, and the other: the door:: weekly, time-consuming and laborious. At the same time, the double cups of the two ugly wheels are mixed, huge, and heavy, unable to move parts and requirements, and the cost is relatively high. The moving tool is lighter and the female is fully considered. No matter the front structure can be directly (four) = early cup or double cup impact design, so, in such as lock;, :, file, will cause the jump function Loss and output the most; ^ Touch the drill or impact function, so that the screw body or the above-mentioned conventional technology is twisted and forced the transmission mechanism can not jump the second wide circumference of the spring, the elasticity of the spring itself is fatigued and By mechanical wear, it will lead to the quasi-phase of the shirt. When the above-mentioned conventional technology is used, the second-gear file will be skipped. The solution is not only more: two r no = 8 M343562, so not only the product ( The durability is greatly burdened. The acquaintance also increases the user's use cost. It can be seen from the above that the switching process of the conventional technology is complicated. "There is no obvious step-type torque change. Wang: The switch is not easy." Various kinds of impacts in the impact-switching, switching-off technology, in fact, T to avoid the conventional [new content], for the purpose of (4) technical problems to be solved. In view of the above-mentioned shortcomings of the prior art, a power tool Compared with the awkward w (three) is to provide soil, 丨: structure '俾 easy to switch gear.
