[0022] Refer to Figures 1-5The utility model provides a kind of angle grinder protection device for fire engineering, including angle grinder body 1, angle grinder body 1 one end bottom is provided with output shaft 103, and output shaft 103 is fixedly connected with angle grinding wheel 101, angle grinder body 1 is close to the side of angle grinding wheel 101 is provided with handle 102, angle grinder body 1 is located output shaft 103 and is fixedly connected with fixed sleeve 2, and fixed sleeve 2 is coaxial with output shaft 103, fixed sleeve 2 circumferential outer wall one side is fixedly connected with semicircle protection 201, fixed sleeve 2 circumferential outer wall is also rotatably connected with rotating ring 3, rotating ring 3 is rotatably connected with fixed sleeve 2, with certain damping effect, rotating ring 3 circumferential outer wall one side is fixedly connected with semicircle baffle 301, semicircle baffle 301 both ends are rotatably connected with the same arc baffle 4 by pivot, semicircle baffle 301 both ends are fixedly connected with side column 5, the side of the mutual far away of two side columns 5 is equipped with recess 501, the top and bottom of each recess 501 is fixedly connected with vertical rod 6, the circumferential surface of each vertical rod 6 is rotatably connected with sliding block 602, each sliding block 602 is rotatably connected with connecting rod 603, and the other end of each connecting rod 603 is rotatably connected outside arc baffle 4.

[0023] In the embodiment, the circumferential surface of the two vertical rods 6 on the top of the sliding block 602 is sleeved with a spring 601, and the vertical rod 6, the spring 601, the sliding block 602 and the connecting rod 603 are arranged so that the arc baffle 4 always covers the angle grinding wheel 101 when it is not subjected to external force. The top of the arc baffle 4 is fixedly connected with a limiting block 401.

[0024] In the embodiment, the top of the semicircle baffle 301 is provided with an arc-shaped observation window 302, and a glass plate is fixedly installed on the arc-shaped observation window 302. One end of the top of the semicircle baffle 301 is provided with a push block 303.

[0025] In the embodiment, the two ends of the arc baffle 4 close to the side column 5 are fixedly connected with a second magnet 304, and the outer side of each side column 5 close to the fixed sleeve 2 is fixedly connected with a first magnet 202. The two first magnets 202 close to each other have the same magnetism, and each second magnet 304 close to the first magnet 202 attracts each other. The first magnet 202 and the second magnet 304 are arranged to facilitate the positioning of the position of the semicircle baffle 301 and the arc baffle 4, so that the arc baffle 4 is better positioned when it is stored in the semicircle protection 201.

[0026] In the embodiment, a plurality of mounting grooves 402 are equidistantly arranged on the bottom of the arc baffle 4, and a rolling mechanism is arranged in each mounting groove 402.

[0027] In this embodiment, the rolling mechanism comprises a U-shaped rotating frame 7 rotatably connected to the top of the mounting groove 402, and a roller 701 rotatably connected between the two ends of the bottom of the U-shaped rotating frame 7. The arrangement of the roller 701 and the U-shaped rotating frame 7 ensures that the arc-shaped baffle 4 does not affect the movement of the angle grinder body 1 when it contacts the component.

[0028] Working principle: when in use, when normally used, the arc-shaped baffle 4 and the semicircular baffle 301 are accommodated on one side of the semicircular protection 201, so that the angle grinder wheel 101 exposed on one side of the semicircular protection 201 can work normally, and the semicircular protection 201 can prevent sparks and iron filings from splashing on the worker during grinding. When used in special places, sparks cannot be allowed to splash, at which time the toggle block 303 is toggled to make the semicircular baffle 301 rotate with the arc-shaped baffle 4 to the other side of the semicircular protection 201. Through the arrangement of the arc-shaped baffle 4, the semicircular protection 201 and the semicircular baffle 301, the angle grinder wheel 101 is fully protected. Through the cooperation of the first magnet 202 and the second magnet 304, the arc-shaped baffle 4 and the semicircular baffle 301 are accommodated in the semicircular protection 201, which is convenient for accurate positioning. During grinding, when the angle grinder wheel 101 contacts the component on the side away from the semicircular protection 201, the component will first abut against the arc-shaped baffle 4, causing the arc-shaped baffle 4 to rotate. Through the pulling of the connecting rod 603, the slider 602 moves upward and compresses the spring 601, so that the arc-shaped baffle 4 does not affect the normal work of the angle grinder body 1 during work. At the same time, according to the user's hand angle, the top of the arc-shaped baffle 4 is always in contact with the surface of the component. Through the arrangement of the arc-shaped observation window 302, the user can clearly observe the position of the angle grinder wheel 101, so as not to affect the working condition of the angle grinder wheel 101. At the same time, the arc-shaped baffle 4 covers the angle grinder wheel 101, so that the flying sparks will not splash out. Through the arrangement of the U-shaped rotating frame 7 and the roller 701, the arc-shaped baffle 4 does not provide a large friction force when the angle grinder body 1 moves, so as not to affect the movement of the angle grinder body 1. When the angle grinder body 1 is used for simple cutting, the toggle block 303 is toggled to change the angle at which the semicircular protection 201 and the arc-shaped baffle 4 together wrap the 101, so as to avoid sparks during cutting, improve safety, and prevent broken angle grinder wheels 101 from injuring the user.
