Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

Please refer to Figure 1-2, the present invention provides a technical solution:

An easy-to-use control switch for a hand-held cutting and grinding machine, comprising a handle 1, a fixing plate 2, a sliding plate 3 and a spring 4, a fixing plate 2 is fixedly connected to the inner side of the right end surface of the handle 1, and the front end surface of the fixing plate 2 is fixedly connected. The left end is provided with a chute a, and the fixed plate 2 is slidably connected to a sliding plate 3 through the sliding groove a. The left end surface of the sliding plate 3 is fixedly connected with a spring 4, and the other end of the spring 4 is fixedly connected to the handle 1. The sliding plate 3. The lower end face is rotatably connected with a first set of rods 5, the lower end of the first set of rods 5 is sleeved with a tilting rod 6, and the tilting rod 6 is rotatably connected with a first rotating rod 7, and the first rotating rod 7 is connected with the The handle 1 is fixedly connected, the upper end surface of the sliding plate 3 is rotatably connected with a second sleeve rod 8, the other end of the second sleeve rod 8 is sleeved with a double-ended sleeve 9, and the center of the double-ended sleeve 9 is rotatably connected with A fixed rod 10, the rear end surface of the fixed rod 10 is fixedly connected with the handle 1, the upper end surface of the double-ended sleeve 9 is sleeved with a third set of rods 13, and the other end of the third set of rods 13 is rotatably connected to a second set of rods Rod 11, the second rotating rod 11 is rotatably connected with the handle 1, a protective cover 12 is fixedly connected to the upper end surface of the second rotating rod 11, and a panel switch 14 is arranged on the inner side of the protective cover 12, and the panel switch 14 is connected with The handle 1 is fixedly connected, the left end surface of the handle 1 is fixedly connected with a baffle plate 15, the left end surface of the handle 1 is fixedly connected with a grinder 16, and the right end surface of the grinder 16 is slidably connected with a protective cover 17.

The shape of the rocking rod 6 is L-shaped, and the sliding plate 3 can be slid by the rocking rod 6. The protective cover 12 is in the shape of a cup cover. This setting can prevent the panel switch 14 from being activated at will. The axis of the spring 4 and the center of the sliding plate 3 are located in the same plane. This arrangement can make the pulling force of the spring 4 on the sliding plate 3 be vertical to the right, reducing the frictional force of the sliding plate 3 on the fixed plate 2, so The angle formed between the lower end face of the tilting rod 6 and the bottom end face of the handle 1 is 30°, and this setting can be done by pressing the tilting rod 6 during use. It is convenient to use. The protective cover 17 is made of a glass block of transparent material. This setup prevents sparks from flying around without compromising the crew's line of sight.

Workflow: When using, four fingers are facing down, thumbs are placed on the handle 1, and the forefinger is used to hold the rocker 6, the rocker 6 will rotate and drive the first set of rods 7 to move to the left, and the first set of rods 7 drive the sliding plate 3 Moving to the left, the sliding plate 3 drives the second set of rods 8 to move to the left, the second set of rods 8 drives the double-ended sleeve 9 to rotate to the left, the double-ended sleeve 9 drives the third set of rods 13 to move to the right, and the third set of rods 8 moves to the left. The sleeve rod 13 drives the second rotating rod 11 to rotate, and the second rotating rod 11 drives the protective cover 12 to move upward. At this time, the thumb presses the panel switch 14, the index finger is lifted, and then the index finger is pressed on the lower end surface of the handle 1, and the sliding plate 3 It will automatically reset according to the pulling force of the spring 4, and the protective cover 12 will automatically descend to cover the panel switch 14. When not in use, press down the tilt lever 6, the protective cover 12 can be raised with the thumb and the panel switch 14 can be pressed down, and the shutter 15 will be closed. To block the hand from being hurt by the frosted plate, when the workpiece is in contact with the protective cover 17, the protective cover will automatically slide upward without affecting the use. This setting is convenient to use and can work for a long time, which is worth popularizing.
