Creation Instructions (1) [The new creation belongs to the creative technique, the purpose mask, and the auxiliary arm. When the first piece is not lowered and the saw blade does not cut the workpiece, the piece is at the end_ [Previous technology press, Xi Silver cover, full effect when sawing the workpiece. The upper saw cover is exposed. Do not cut the workpiece. The saw blade may be cut off when it rises by mistake. In addition, it may be overwritten, but it is only applicable to the technical field of repeated sawing and inseparable effects.]: The practicality of making the circular misalignment better is: the gap in the saw cover of the saw blade; Γί and safety function ;. The main θ ^ ^ > the auxiliary auxiliary cover without a rotatable angle and the machine are provided with a song composed of flute, ancient $ 1 and two linkage arms _ _ ^ ^ rotation angle, so, you have to form a saw When the cover saw does not cut the workpiece, the auxiliary cover — Shan, Tai η, Thousand's full effect of the full cover of the saw cover. When the saw cover blade is lowered, the two-link arm can automatically pull to open the auxiliary cover to expose the mine. It is free of manual operation and convenient to use. J: Know: The structure of circular saw saw cover, all are: circular saw blade-half is set up and a part of the saw blade is cut out for sawing the workpiece. When the circular saw blade is lowered, the circular saw blade is covered with saw f To achieve the safety of avoiding accidental injury to the person '[, it has the following disadvantages: Because it does not have a gap in the auxiliary cover package, when the saw cover saw blade does not fall (rise) =, the saw blade must be exposed. In addition, the danger of injury due to exposure. In particular, after the saw blade rotates at high speed, although the source is still on, there will still be the phenomenon of inertial rotation. It is easier to accidentally injure people. 1 At the gap where the saw cover exposes the saw blade, add The auxiliary hoods provided with an auxiliary hood package are all required to be manually closed and removed. When the workpiece is not cut for a long time, it is not suitable for the situation where reverse recording 1 is required for a short time. Are too lazy to cover repeatedly, take time and convenience, but often not used, resulting in unsafety

[New content]: Please refer to Figures 1, 2, and 3. The machine 1 has a motor M that can be integrated and lifted, a handle 3, a saw blade 2, and a spring 5. The outer periphery of the saw blade 2 is notched. The wrong cover 10 'has a gap to expose a part of the ore sheet 2 for tapering, and it is also provided with an auxiliary cover 20, a first linking arm 24, and a second linking arm 26; wherein the outer side of the mine lift 10' A shaft post 11 is provided at the center, and a fulcrum post 12 is provided at the setting of the outer side; the auxiliary cover 20 can be set to be transparent, and a shaft seat 21 is provided at the center, and the shaft _ seat 21 is exactly fitted It is integrated with the shaft post 11 of the saw cover 10 and is pivoted together to form a rotatable angle of the auxiliary cover 20. The auxiliary cover 20 is provided with a connection hole 23 at the setting position. In addition, the shaft cover 21 of the auxiliary cover 20 is provided with a bearing 22. The hole of the bearing 22 can fit the shaft 11 of the saw cover 10, and the bearing 22 can make the auxiliary cover 20 rotate more smoothly when the angle is rotated; 'The first and second linkage arms 24, 26 are pivoted at one end. The combination is rotatable. The other end of the first linkage arm 26 is pivotally connected to the connection hole 23 of the auxiliary cover 20, and the other end of the first linkage arm 24 is pivotally combined to the machine 1. The first linkage 24 and abutment on the fulcrum column 12, when the ore cover is moved up and down, the first link arm ⑯24 is formed, and the fulcrum column 12 is used as the fulcrum to move the second link arm 26, and then the auxiliary cover 20 is rotated; in addition, the The first linking arm 24 is provided with a fulcrum groove 250 at the end with a convex portion 25. The convex portion 25 and the fulcrum groove 250 can keep the first linking arm 24 against the fulcrum post 12 of the miscellaneous cover 10, and the saw cover 10 A bearing 13 can be sleeved on the outer periphery of the fulcrum post 12, so that the first linkage arm 24 abuts on the bearing 13, so that the effect of the first linkage f 24 changing smoothly and reducing wear is obtained.
M271635 創作說明（3) 【實施方式 如圖三（A)所示，不使用鋸切工件時，鋸片2鋸罩 10整體呈較南（上升）位置，此時辅助罩2〇係呈全包覆鋸 罩10之缺口，使鋸片2不外露，而得不誤傷人之安全功效 。當欲鋸切工件時，使用者手握握把3下壓、並使其開關4 (如圖一所示）呈通電狀態，得鋸罩10鋸片2整體彎弧角 f下降（如圖三B所示），此時因第一連動臂24下端連 :於不動之機台1，而鋸罩10之支點柱12軸承13係在改變 角度位置，因此，可推使第一連動臂24變化角度，即是可 ⑩形成第一連動臂24往後拉動第二連動臂26之作用，又因輔 ，罩20樞組於鋸罩10中心處（軸柱u)，故第二連動臂26 拉動輔助罩2 0向上凝轉角度，即是可使輔助罩2 〇打開讓 雜片2露出供鋸剖工件（如圖三◦所示）。 當鑛切完成而呈鋸片2鋸罩1〇上升脫離工件時，鑛罩 B上升得使其支點柱12軸承13向上頂推第一連動臂24，令 第:連動臂24反向往回復原狀動作，此時第二連動臂26 ^ 與，:連動臂24樞接，故第二連動臂26可呈向下彎角度， =是第二連動臂26向前、向下之彎弧角度動作，而得^使 ❶辅助罩20反向旋轉，即是可包覆鋸罩1〇缺口處之鋸 如圖三A所示）。 由上述說明可知，本創作得於鋸片未鋸切工件時呈辅 助罩20全包覆鋸片，於鋸片欲鋸切工件之下降過程時，斤 自動打開輔助罩20，又於鋸切完成鋸片脫離工件之過程= ’亦得辅助罩20自動蓋合包覆鋸片，完全免人工操作輔^M271635 Creation instructions (3) [The implementation is shown in Figure 3 (A). When the workpiece is not used for sawing, the saw blade 2 and the saw cover 10 are generally in the south (raised) position. At this time, the auxiliary cover 20 is inclusive. The notch of the saw cover 10 prevents the saw blade 2 from being exposed, so as not to accidentally injure people. When sawing a workpiece, the user presses down on the grip 3 and makes the switch 4 (as shown in Fig. 1) in an energized state, so that the overall bending angle f of the saw cover 10 and the saw blade 2 decreases (see Fig. 3). (Shown in B), at this time, because the lower end of the first link arm 24 is connected to the stationary machine 1 and the fulcrum post 12 bearing 13 of the saw cover 10 is at an angle change position, therefore, the first link arm 24 can be pushed to change The angle is that it can form the first linking arm 24 and pull the second linking arm 26 backward. Due to the auxiliary, the cover 20 is pivoted at the center of the saw cover 10 (shaft post u), so the second linking arm 26 is pulled. The auxiliary cover 20 is coagulated upward, that is, the auxiliary cover 20 can be opened to expose the miscellaneous piece 2 for sawing the workpiece (as shown in Figure 3). When the ore cutting is completed and the saw blade 2 saw cover 10 rises away from the workpiece, the mining cover B rises so that its fulcrum post 12 bearing 13 pushes up the first link arm 24 upward, so that the link arm 24 reverses to return to the original state At this time, the second linking arm 26 ^ is connected to the: linking arm 24, so the second linking arm 26 can be bent downward, = is the arc angle action of the second linking arm 26 forward and downward, and It is necessary to make the ❶ auxiliary cover 20 rotate in the reverse direction, that is, the saw that can cover the gap of the saw cover 10 is shown in FIG. 3A). As can be seen from the above description, the present invention can be obtained by fully covering the saw blade with the auxiliary cover 20 when the saw blade is not cutting the workpiece. When the saw blade is about to cut the workpiece, the auxiliary cover 20 is automatically opened and the sawing is completed. The process of the saw blade detaching from the workpiece = 'You also need to cover the saw blade automatically with the auxiliary cover 20, which is completely free of manual operations.
