New description: [New technical field] The present invention relates to a device for protecting a shifting mechanism of a power tool. [Prior Art] A power tool for drilling, locking, etc. is conventionally configured to transmit power of a motor to an output shaft via a gear system, thereby achieving a shifting function of deceleration or increasing speed; in order to achieve deceleration or speed increase The effect of current power tools is usually to have a mechanism to change their output speed. In addition, depending on the application, the gears of general power tools usually include three-speed rotations of low speed, constant speed, and high speed. The control method of the different speed output is to set the shifting mechanism connected to the flip in the body of the electric private body, and the shifting mechanism can be controlled when the push button is moved forward or backward by a straight line. The position of the position, so that the output shaft outputs the desired speed. As soon as the switch is pressed, the general power tool has a press _ off, the user will start the motor when the switch is pressed, and when the button is released, the horse 'The power tool_bit switching device is not protected, 'μ while the motor is running, the user can report it, use it, and cause the parent/person == force component to be damaged. Dare to even make the machine [New content] The gear shifting device of the tool The main purpose of this creation is that the electric M332563 has no f protection, so that it is easy to be accidentally touched and cause damage to the machine. The feature of the creation is that an outer ring is arranged on the outer casing of the power tool, and the push button in the outer switching mechanism is rotated and rotated, and the number - 丨 < ° is connected to a right-handed from ~,, > There are a number of clamp holes, and the button opens ^, the clamp piece 'When pressing the button to start the motor operation two = _, the card is inserted into the __ hole, __

Compared with the conventional power tools, the switching mechanism of the present invention is well protected, so that it can avoid accidentally touching the push button due to inadvertent or external force during the operation, thereby preventing the shifting mechanism from being reported. . M332563 [Embodiment] The following is a more detailed description of the implementation of the 70-symbol symbol in the figure, so that those skilled in the art can implement it after studying this specification. Illustrated in the first and second drawings, a structure of a power tool is provided, which is provided with a Wei mechanism 4 at the =1 _ section, and the shifting mechanism 4 is composed of a planetary gear train and a plurality of sorrowful gears. The motor gear 6 is driven by a motor (10) (not shown), and after the rotation speed is converted by the speed change mechanism 4, the output shaft 7 finally receives a (four) force. The shifting mechanism i is connected to a switching mechanism 3; as shown in the second figure D, the switch has a puller 33, and both ends of the pull rod 33 penetrate from the groove n on both sides of the outer casing i into the outer casing and connect the shifting The mechanism 4 is further combined with the outer periphery of the outer casing — - the outer ring 2 (as shown in the second c figure). The wall surface of the outer soil 2 is provided with a through-folded and meandering gear groove 21 at a suitable position on the wall surface of the outer ring 2. There are also a plurality of positioning holes arranged along the circumferential direction thereof. If the tool includes three stages of high speed, constant speed and low speed, the creation also includes a second hole = u hole 22B and a third The positioning holes are as shown in the third figure). This creation will smash the gear slot 21 of the ghost 32 teeth over the outer ring 2 to the tie rod 33 (as in the second B diagram:) - 'Right, the push button 31 is combined with the slider 32 (as shown in the second figure A) Show). No. 2 4 is not created in the power tool body to control the motor to start the port: the second switch 5 is connected with a positioning piece 5 with a - cassette 511;: on the diameter, when 1 in the second positioning hole When the circumferential path of the 22A to the third positioning holes 22C is inserted into the clicker 551, the push button switch 5 can be used to pull the 乂/, the middle one of the boring holes to prevent the outer ring from rotating. :W's Bao Wei set 'When the button 5 is not pressed, the motor does not start, the latch 5J1 on the positioning piece 51 of the M332563 is not inserted or rotated, so the user can dial her 3 隹 hole (4) outside Ring 2 can be freely _ change the speed, · Because slip (10) is located in the broadcast slot: when the block 32 is off the pole 榫 5n; if the city solves the frequency, can make the second card 511 '· or switch to the low-speed building, The third positioning hole, 榫 511 '· at this time press the button switch 5 to start the motor, the card 511 = insert the first - _ 22A, the second positioning hole or the third button, let the outer two... , and go. In other words, in the state where the outer ring cannot be rotated, the push (4) can not be moved even if it is subjected to the action of force and force, thereby protecting the shifting mechanism in the outer casing and avoiding the mechanical parts.
