New Description: [New Technology Field] This creation is about the brakes of a kind of power tools. [Prior Art] It is known that there are a lot of power tools, such as gardening tools such as portable lawn mowers. These image force tools are the cranes and cranes (4), and the tools installed on the output shaft (Example (4) , ugly, etc.). When the action is stopped, although the mail engine no longer provides any driving force to the output shaft, the output will generate additional output due to the loss of __. Small lack of turn. At this time, if the pure lion cutting tool is installed on the output shaft, the operator may be surprised, and the accident is likely to occur. The lighter is additionally cut to the part being processed, which affects the processing accuracy; more serious is Risk of injury to the operator. Therefore, in order to reduce the risk of the power tool, the brake device of many power tools has been developed. When the engine is stopped, the operator can read the money and the output shaft can be stopped immediately. In the case of Taiwan Patent Publication No. 36, a "mountain sawing machine for a table saw" is a centrifugal plate that is attached to the heart of the motor casing, the shaft is rotated, the centrifugal device, and the - brake plate are finely packed. The contact between the bearing and the bearing of the motor produces a braking effect. When the motor power is turned off, the motor speed is rapidly slowed down and the centrifugal force is weakened. The sea away from the plate will drive the braking body into contact with the pomelo bearing, and the friction braking effect can be achieved, and the motor spindle can be stopped in a short time. M284781 In the case of the sensitive car ^ brother 4793064, 'disclosed the brakes of the power chain saw, there is no ... in the basin, the handlebars, the frame of the brakes, ', by ordering the handlebars, so that the brake steel belt is close to ^ = Winter parts, the user can force the wheel to stop. ..., 摩擦 煞 煞 钢 上述 上述 上述 上述 上述 上述 上述 上述 上述 上述 上述 上述 上述 上述 上述 上述 上述 上述 上述 上述 上述 上述 上述 上述 上述 上述 上述 上述 上述 上述 上述 上述 上述 上述 上述 上述 上述 上述 上述 上述 上述 上述 上述 上述 上述Shirt, complex structure, t; 1Γ1 ° ^j 吏=P to let go of the throttle, stop the engine's action, still need to take a step to stop the output _ sexual rotation, operational comparison. Therefore, it is indeed necessary that the miscellaneous work is quite simple, the number of parts is small, the weight is light, and the cost is relatively cheap. [New content] It is mellow to the above problems, so the design of the creator is deliberately designed. Out of this creation. The brake device of the power tool of the present invention mainly comprises a brake assembly, a bearing part and a pinion gear, wherein the wheel part comprises a brake base, a base cover, a first throttle line and a second oil line 'oil pressure block. , throttle line guide column, brake action block, brake guide column, bomb I, brake steel belt and brake drum. The brake base and the base cover enclose the outer casing of the entire brake assembly to accommodate other components in the space formed between the two. The end of the first-oil line is connected to the carburetor, and the other end is connected to one end of the 6 M284781 of the brake actuating block, and an elastic cyanine is arranged between the first throttle line and the brake actuating block. The second line of the second oil (10) is connected to the throttle, and the other end of the second oil (10) is connected to the other end of the brake car, so that the 2-oil line, the brake actuating block and the second throttle line are linearly connected in series. The contour of the car's actuating block is designed to have two bevels, which can be respectively released with the brake guide column in a parking position, and the position f is closely attached. The other end of the 煞 柱 column and the brakes are in pure contact. ▲+杰ΐ车钢τ. The material guide column is sleeved with a section, and the length of the steel strip is set to be sufficient for the age of the earth (four) in the drum, and the ribs stop the rotation of the drum. = Under normal circumstances, when _ is not refueled, the _ moving block has no car guide column at the ‘vehicle position. At this time, the brake steel belt is close to the brake drum, so the brake drum cannot rotate. When the second tool pulls the first throttle line to open the carburetor, it will drive the brake throttle to m-throttle line to be pulled in the direction of pulling, and then refueling by the second brake to make the door open. When the moving block moves, the brake guide column moves along the slanting surface of the car and the moving block to the 篦-moving to the younger-slope surface, so that the two enter the release position. In the middle:: the brake guide column is squeezed 'Make the end of the brake steel 2 煞 car drum' money car drum can be rotated with the output shaft, this day, the normal use of power tools 0 line and brakes to reduce the resilience between the material, Dimen line along the first - The oil sling line resumes the direction of the brake position, and the brake guide column moves back to the first slope along the two inclined planes of the moving block, so that the two recover the brake position. As a result, the M284781 also hinders the steel belt from being damaged again. The drum is stopped, and the rotation of the brake drum is stopped, and the inertia of the output shaft is stopped. Disc—According to the above, this creation # is the _ brake device, the throttle line is divided into the first throttle line, the brother-one machine line is connected to the brakes in the middle, and the fine oil line is used to control the position of the vehicle. Wheels and _ belts, directly _ use or release ... role ' without the need for additional brake handles and brakes pivoting a lot of material, can achieve the advantages of fewer parts, , ·, σ structure, etc. Because of the second; the amount is reduced, the manufacturing is done in the (four) _ 丨 ... car _ can be received _ between the _ tightness of the eight system ' so the user only wants to release the throttle, it automatically brakes, no need to additionally press the wire handle The operation and the operation are quite convenient. [Embodiment] Hereinafter, the brake device of the power tool of the present invention will be described in detail with reference to the accompanying drawings. It is basically divided into several parts: - brake assembly (10), bearing coffee wheel box coffee. The brake group includes a base on the brake guide column 4, brake brake block 5, the first - throttle line 8 _ ^ door up line = ΓΓ line guide column 9 , brake base 11 and brake drum _ main = cattle. 3 The present and brake base 11 is used to define the entire brake cylinder member (10). Its parts are housed in the space formed between the two. The double '8' can be included in the 8 M284781 bearing portion 200 - bearing pressure plate 16, bearing i7 And the main gearbox such as pinion i8 includes - gearbox upper cover 21, bearing four, c-type buckle 7 output shaft 25, eccentric block 27, such as 8 and gearbox lower cover 36. In this creation, As a paradigm, a blade assembly 29 is assembled on the wheel shaft 25. The f-track is that the output shaft 25 can be assembled in other forms, such as "1 film or marriage." The department and the gears are not the characteristics of this creation, which can make the structure of the job known to him. Therefore, in the book of the creation, the detailed description of the bearing part and the gear box is omitted. Eight=, start the brake assembly (10) Scale structure. Refer to the third to fourth figure, the perspective view and plan view of the knife, , and , to create the state of the position of the brake assembly (10), in which the cover i of the base is removed for observation. The first throttle line 8 = Ι = Γ carburetor (not shown) on the 'the other end is passed - The bomb* is connected to one end of the brake block 5 in the assembly 100. Immediately outside the brake assembly, the oil guide line 9 and the nut 1G are arranged so that the first throttle line δ energy domain (four) The electric ship can be moved along the guiding direction of the inter-line guide post 9. The second W 糸 of the second throttle line η is connected to the state (not shown), and the other is connected to the other of the car damper 5 One end is set in the brake assembly (10) - the oil line Wei 6 so that the second throttle line 2 can be held on the brake assembly. Thus, the first-oil line 8, the brake actuator 5 and the first-throttle line 13 The linear arrangement is shown in series. The porch of the brake actuating block 5 is implemented as a slanted-slope 5a and a second slanted surface, when the brake guide 4 abuts against the first slant, 5a A brake position, and the brake guide 4 abuts against the second slope. At this time, it is called 9 M284781. The other end of the brake guide 4 is in contact with the brake actuator 8 and is connected to the bracket to be fixed on the brake base u: The scoop is set on the ° ° and #弹耳 3. The length of the brake steel strip 2 is designed to be close enough to the end of the money drum 14 (4). =' Describes the actuation of the brake assembly. As shown in the fourth figure, when the user's rth throttle line 8 is not pulled, the elastic force of the spring 3 is pushed to the sensitive beam, so that the first inclined surface 5a of the shunting car 5 is closely attached to the car guide post. 4 Where is the "car position, at this time the brake steel belt 2 is close to the brake drum 14, so the brake drum 14 benefits the reference to the fifth picture, when the user pulls the first throttle line 8 (that is, the carburetor is turned on) , the brake actuating block 5 and the second throttle line 13 are moved along the direction in which the first throttle line 8 is pulled, and the second closing line (4) is used to move the oil; when the brake lying block 5 moves, the 柱^ column 4 Then, the first slope % of the fresh motion block 5 is moved to the second slope surface %, so that the two enter the position of the release. In the position of the arrangement, the brake guide column 4 is pressed by the carriage 5, so that the tension is tightened. When the brake steel strip 2 is loosened, the brake drum 14 is released, and the brake drum U can rotate freely with the output shaft 25, and the power tool can be used normally. The user releases the first throttle line 8 (ie, closes) In the case of the carburetor, the restoring force of the spring 3a existing between the first throttle line 8 and the brake actuating block 5 forces the brake actuating block 5 and The second throttle line 13 moves along the first throttle line 8 to resume the braking position, and the throttle is also closed. The brake guide 4 moves north along the second slope of the brake actuator 5 back to the first inclined surface 5a, and the spring 3 pushes again. The brake guide column 4 is in close contact with the first inclined surface 5a of the brake actuating block 5, so that the two positions are restored to the braking position, so that the brake steel strip 2 is again tightly wrapped with M284781 ..., and the vehicle branch 14 stops the brake drum μ Rotation, at the same time, also prevents the inertia rotation of the output shaft 25. ―According to the above, in the brake assembly of the present invention, the -off line is divided into a second section of the first throttle line 8 and the second oil sling line 13, and the two are connected to each other. 5, _ throttle line to control the position of the brakes for the pure 5, into the * with the car guide column 4 and the brake steel belt 2, directly generate the brake effect or view the side of the section needs additional car handles, touch the pivoting components and other parts, The structure is simplified, and many of them can achieve the advantages of a small number of parts, a simple modular structure, and a reduction in the cost of the core. In addition, since the brake side can be said to be synchronously controlled by the tightness of the throttle line, the user Just release the room, just Automatic braking, completely does not require the book to press down the scale handle, it is quite convenient to operate. Although the creation has been described according to the above embodiment, it is known that for those who are familiar with the technology, Wei After the _ red, other modifications and equivalent substitutions can still be envisaged. Therefore, the aspects of the creation should not be limited by the specific embodiments described above, and should be defined by the following patent application scope.
