New description: [New technical field] [0001] A safety trigger structure for a power tool, in particular a power tool trigger structure with a safety switch. [Prior Art] [0002] Small power tools (including pneumatic or electric) are popular because of their small size, low price and low energy consumption, and the power tools include a variety of variations, such as grinders and drills. , pneumatic (electric) wrench and other types. [0003] A conventional power tool can be found in the Chinese Civil Religion Patent Notice. No. 4 〇 1 908 ", · · The safety switch of the power tool's push switch _: 改ΐ良The previous patent system V. ;; ' ' . The one side of the press-opening relationship is set on the side of the air. The body is above the air control valve stem, and the other side of the push switch has a long slot and two piercing lugs are preset. The safety member can be pivotally connected to the long slot in the long slot, and the pin is not provided with a torsion spring. The torsion spring is abutted against the inner end surface of the push switch, and the other end One side is abutted against the safety stop, and the safety block has a stop edge above it, so that the safety block and the grip of the pneumatic tool body are at an angle of a pure angle, so that the safety stop can stop The push switch is pressed so that the push switch cannot be pressed down without pressing the air control valve stem, and when it is intended to be used, the safety stop must be pivoted forward to press the push switch to press the interlocking air control valve. a rod; the feature is: the push switch is pivoted by a safety push block The lower part is provided with a slot for pivoting a pulley, so that when the safety stop is pivoted forward, the lower pulley can be in contact with the upper end surface of the pneumatic tool base grip - the pivot form number Α 0101 3 Page / Total 18 pages 1099015 Smoother and smoother, more convenient and convenient to operate. However, the safety block is mounted on the exterior of the power tool and is an easily movable stop structure. It is possible for children or pets at home. When the pulley is installed under the safety stopper, it is more likely to be displaced from the stop state due to vibration or collision, and it is easy to accidentally touch and start to cause danger. [0004] Another prior patent such as the Republic of China patent certificate No. M259674, "Improvement of Pneumatic Tool Safety Start Switch", the prior patent discloses that a pneumatic tool is provided with a push button and a linkage block, and the push button and the linkage block can select the movement of the stop plate by the user.

[0005] The conventional pneumatic tool protection mechanism is all moving; the trigger of the pneumatic tool, by limiting the trigger action: the cloth is more 丨 open. However, under the experience of actual operation, it is found that under the good habit of the operator, the conventional safety switch does not automatically return to the state of the lock state after being turned on, and may still cause 矣. If the pneumatic tool is not grasped during use, it may cause danger due to improper operation and excessive power output, which may make the user unable to operate stably. [New content] [0006] In view of the conventional power tool, the safety protection device may be unintentionally released and malfunction, so the purpose of the present invention is to provide an improved safety starting mechanism, which is set on the trigger pressed by the user. There is a gap and a safety switch, and a safety actuating mechanism can be provided to avoid false start. [0007] This case is a safety trigger structure of a power tool, which is a power tool form No. A0101 Page 4 / 18 pages M399015 has a switch The power tool is controlled by the actuating switch to determine whether to operate. The power tool further includes a trigger and a safety switch, wherein the trigger has a track and a trajectory on the trigger displacement of the trigger that prevents the trigger from interlocking a gap of the actuating switch. The safety switch package is a force applying member for pushing by a user and a linking member coupled with the force applying member, wherein the force applying member is mounted on the track of the trigger and can be applied by the user. The orbital displacement. The linkage member includes a starting position in the displacement path interlocked by the force applying member to abut the trigger switch.

Because the trigger was accidentally pressed: move. And % safety, the switch can start the power tool with the trigger of the user under the force of the user, and the power tool is not affected in normal use. [Embodiment] [0009] The present invention is a safety trigger structure of a power tool. The technical content of the present invention will be described below in conjunction with the drawings. Please refer to FIG. 1 to FIG. 3, which shows a part of the appearance of the tool body 1 of a power tool. The present invention does not limit the shape of the power tool. The power tool can be a common grinding machine or a drilling machine. The power tool can be a pneumatic tool or an electric tool. Any simple replacement that can be easily considered by those skilled in the art should be included in the scope of the patent application scope of the present application. The trigger body 2 is coupled to the tool body 1 for the user to control the operation of the power tool. As shown in FIG. 1 to FIG. 3, the trigger 2 has a joint portion 20, and the joint portion 20 is limited to the tool through a positioning member 10. On the body 1. And the trigger 2 is pressed by the user according to the form number A0101, page 5/18, M399015, with the clamping element 10 as the sleeve and having the pressure displacement. The tool body 1 further includes an actuating switch U, and the actuating switch 11 is triggered or not to determine whether the power tool is actuated. The trigger 2 is provided with a notch 21' and the position of the notch 21 is just on the trajectory of the trigger 2 being displaced by the trigger 2 so that the trigger 2 cannot interlock the actuating switch 丨丨. In other words, after the trigger 2 is pressed, the position of the notch 21 happens to be located on the actuating switch 11, so that the simple pressing of the trigger 2 cannot start the power tool β. There is a track 200 on the 2, and a safety switch is arranged in the case to be displaced along the track 2〇〇 on the trigger 2. The safety opening relationship is composed of a force applying member 3, a linkage rod 31 and a linkage member 32, wherein the force applying member 3 is mounted on the rail 2'': a miscellaneous, drunk. A connecting portion 30 is applied. Connecting the slats 3 such as _3 () through the track 2 〇〇 extends to the other side of the trigger 2, the face Iv: the brother _ bar 3 丨 is also located on one side below the trigger 2 . In order to guide the movement of the linkage rod 31, the trigger 2 is provided with at least one limiting portion 22 for the linkage rod 31 to pass through to limit the displacement range of the linkage rod 31, and the interlocking sleeve 31 has a resilient member. 33 is respectively abutted on the connecting portion of the limiting portion 2, 2 and the urging member 3 to provide the elastic force of the urging member 3 to return. The other end of the connecting rod 31 is connected to the linking member 32. Therefore, the user of the force member 3 pushes and pushes through the connecting portion 30 and the interlocking lever 31 to drive the linking member 32 to move. The linkage member 32 includes a displacement position in the coupled displacement rail that can be abutted against the actuation, that is, after the linkage member 32 is displaced to the activation position, the pressed displacement of the trigger 2 is matched. The linkage 32 can be caused to trigger the actuation switch to "start" the power tool. [0010] For the safety design of the above trigger 2, please refer to FIG. 4_Buxin_2, wherein the chart 箪 No. A0101 δ page / 丨 8 pages M399015, Fig. 4-2 respectively represent the safety switch does not operate, and the trigger 2 is activated. Two schematics. As can be seen in FIG. 4-1, the trigger 2 is in a normal position that is not pressed by the user, and a resilient member 100 is also connected between the trigger 2 and the tool body 1 in FIG. 4-1. The resilient member 100 provides its returning spring force after the trigger 2 is displaced. After the trigger 2 is pressed, as shown in FIG. 4-2, since the notch 21 on the trigger 2 just corresponds to the position of the switch 11, the actuator switch 2 is pressed through the notch 21 after the trigger 2 is pressed. The actuation switch 11 is triggered. This design avoids inadvertent force or a child accidentally touching the trigger 12.
