Description of the new type: [Technical field to which the new type belongs] The present invention relates to a polishing machine, particularly a polishing machine with a braking effect and a quick stop for the sanding disc, and an auxiliary quick stop rotation structure. [Prior technology] For the existing polishing machine, please refer to the new patent case No. 529515 "Improved Structure of Pneumatic Sanding Polishing Machine". The overall structure u is shown in the case Φ, which is driven by pressure gas inside the polishing machine body. The power motor uses the power motor to drive the eccentric shaft set at its axial position to rotate, and the bottom of the eccentric shaft is eccentrically pivoted with a rotatable sanding disc shaft center, and is combined with the bottom of the sanding disc shaft center for polishing Sanding disc. When the polishing machine is used, the eccentric shaft is driven by the power motor to rotate, so that the eccentric sanding disc axis oscillates and rotates, so that the sanding disc combined with the sanding disc axis will reciprocate horizontally and can be used for friction polishing. The surface of the object. However, when the polishing machine wants to stop, the power motor stops rotating and has a certain braking effect, so that the eccentric shaft directly linked to the power motor stops quickly, but the axis of the rotating sanding disc will continue to rotate for a while, making It takes a while for the sanding disc to settle, and it takes time to wait for the sanding disc to stop, causing inconvenience to use, or someone presses the bottom of the sanding disc to the ground and stops the sanding disc quickly by friction, but this way However, it will cause the wear of the sanding disc, which is not economical and needs to be improved. [New content] Due to the disadvantages of the existing polishing machine that requires a lot of time to wait for the sanding disc M279440 after use, this creation is a polishing machine with an assisted rapid stop rotation structure. The brake unit is designed to reach the sanding disc faster. The effect of stopping. In order to achieve the above purpose, this creative system includes two aspects. The first energy system includes: ^ The polishing machine body, which is provided with a ring-shaped dust cover on the periphery of the bottom of the polishing machine. It is set in the body of the polishing machine, and an eccentric shaft is extended downward at the bottom axis position, and the eccentric shaft is eccentrically pivoted at the bottom. The center of the sanding disc, which can rotate, is the top of the center of the sanding disc. A screw is provided, and the screw is combined with the shaft center of the sanding disc. The dust cover is provided with a plurality of braking units at equal intervals around the bottom. Each braking unit is provided with a cylinder, and the cylinder is screwed on the cylinder. The bottom of the dust cover can be lifted up and down, and a large head is formed at the bottom of each cylinder. A friction body is provided at the bottom end of the large head, and each friction body abuts the top surface of the sanding disc. Preferably, the dust cover is provided with a plurality of cylinders at an equally spaced ring at the bottom. Each cylinder is provided with vertical screw holes, and the screw units are screwed with the screw holes, and the friction system brush body. The second aspect includes: a polishing machine body, a ring-shaped dust cover is provided at the periphery of the bottom of the polishing machine body, and a power motor is installed in the body of the polishing machine and is positioned at the bottom axis. An eccentric shaft is extended downward, and the bottom of the eccentric shaft is eccentrically pivoted with a rotatable shaft center of a sanding disc, a sanding disc, a top end of the sanding disc is provided with a screw, and the screw is combined with the shaft of the sanding disc. Among them, the dust cover of M279440 is provided with a plurality of braking units around the bottom, and each braking unit abuts the top surface of the sanding disc. Preferably, the braking unit is a convex post formed on the bottom of the dust cover. When this creation is used, the power motor drives the sanding disc to swing for friction polishing. When the power motor stops, the brake units contact the sanding disc. As a result, a predetermined friction force is applied to the sanding disc to make the sand When the disc loses its power and rotates, the abrasive disc can achieve a faster stopping braking effect due to the friction force applied by each braking unit. [Embodiment] This creation is a polishing machine with a structure for assisting rapid stop rotation. Please refer to the first preferred embodiment of the first to fourth figures, which includes: a polishing machine body (10), a polishing machine body (丄 〇) is a shell with an open bottom, and an inlet valve (work 1) and a dust collector (12) are respectively extended above and below one side. 'With a dust collection tube (12) and a polishing machine ( 1 0) The lower side of the interior of the body communicates with each other and can be used for air extraction and dust collection. The polishing machine body (1 0) is pivotally provided at the top with a plate press (1 3) that can press and control the intake valve (work 1). ). A power motor (20). The power motor (20) is installed on the upper side of the polishing machine body (1 0) and provides a power source through an air inlet valve (i 丄) connected to the air pressure source. In addition, the power motor (2 Q) can also be the type of electric motor. There is no limitation in this creation. The power motor (20) is provided with an eccentric shaft (2 1) at the bottom axis position, and the bottom of the eccentric shaft (2 1) It is a counterweight crankshaft part (2 1 1). The counterweight crankshaft part (6 M279440 2 1 1) is a long part (2 1 1) with one end protruding outward and horizontally eccentrically pivoted at the bottom. Heavy crankshaft). The center of the sanding disc (2 2 dust cover (30A), the dust cover (an annular body forming a ring supporting part (3 1A), 0 A) is the peripheral edge of the peripheral edge toward the bottom of the polishing machine body (10) The inner circumference of the dust is combined with the bottom equally spaced ring with 12 cylinders (3 2 A cover (30 A) and A) with vertical screw holes (3 2 1 A). (3 2 1A) A screw car unit 卩 is screwed together, which is inferior to each screw hole (32 ,, dry early 70 (40 A), each Min A) is provided with a screw screwed to each screw hole (3, 2, 3) (4 0, the cylinder (4 1 A) is a stud and is connected to the cylinder; the body (4 1 A) is a large head (411A), which forms an A in this preferred embodiment) is a hexagonal block. The head (4 °° 4 1 1 has a friction body cuw and the bottom extends 2A) is a brush body. In addition, the number of cylinders (32A) is less than two. The number of Wu i 4 〇A can be increased or decreased as needed, It is not necessary to make equal intervals between each other. :: It is also possible to attach the cylinder (4 7 to the bottom of the dust cover (30A) without a cylinder (3 2 A). In this preferred embodiment, the grinding disc (5〇) 'The sanding disc (5Q) is a disc body larger than the dust cover (and is located under the dust cover (30A). The sanding disc (50) is vertically extended from the center of the top surface to a vertical direction. A screw ($ " 'A screw (5i) is screwed to the bottom of the sanding disc axis (2 2), and the sanding disc (5 0) The peripheral edge of the top surface contacts the M279440 friction body (4 2 A) of each brake unit (4 OA) and is rubbed by it. The more consistent embodiment is a modified dust cover 改良 /, ο Π R, ^ soap (30A), wherein the dust cover (JOB) is not provided with a cylinder (32a, ^ 3, ^ J Λ), and on the outer periphery to the next iridium shoulder (3 1 β), and there are several brake units (4 〇Β 、 The raft A πτ is a cylindrical convex column (and each convex column (4
