[0034] The switch member 201 includes a strip groove 201a, a sliding frame 201b, a paddle 201c, a connecting plate 201d, a pulley 1 201e, a fixed frame 201f and a pulley 2 201g. The strip groove 201a is opened on the side of the support plate 101, the sliding frame 201b is slidably set on the inner side of the strip groove 201a, the paddle 201c is fixedly set on the side of the sliding frame 201b and slidably set on the side of the support plate 101, the connecting plate 201d is fixedly set on the inner side of the sliding frame 201b, the pulley 1 201e is rotatably set at both ends of the connecting plate 201d, the fixed frame 201f is fixedly set on the side of the connecting plate 201d, and the pulley 2 201g is rotatably set on the inner side of the fixed frame 201f.

[0035] The clamping member 202 includes an L-shaped frame 202a, a rubber sheet 202b and a bending plate 202c. The L-shaped frame 202a is slidably set on the side of the support plate 101, the rubber sheet 202b is fixedly set on one side of the L-shaped frame 202a, and the bending plate 202c is fixedly set on the side of the L-shaped frame 202a. The side of the bending plate 202c is slidably connected to the pulley 201e. The bending plate 202c is bent as a whole, and gradually protrudes inward from both sides, and is slightly concave in the middle. The concave here is used to limit the movement of the switch member 201.

[0036] The reinforcement 203 includes a fixed frame 203a, a rocker arm 203b, a bent rod 203c and a top rod 203d.

The end of the rocker arm 203b away from the fixed frame 203a is rotatably arranged on one side of the bent rod 203c, and the top rod 203d is fixedly arranged on the side of the support plate 101. The top rod 203d and the rocker arm 203b are abutted. The bent rod 203c is bent as a whole, and is convex from both sides to the middle toward the side away from the support plate 101, and is slightly concave at the center. The concave here is used to limit the movement of the switch member 201.

[0037] Usage process: During specific use, first fix the guide rail mechanism on both sides of the metallographic grinder and polisher, and then set the protective cover on the side of the guide rail. First, place the L-shaped frame 202a on the upper and lower sides of the metallographic grinder and polisher, and then the staff slides the paddle 201c to the center of the support plate 101, and the paddle 201c moves through the sliding frame 201b, and the sliding frame 201b simultaneously drives the connecting plate 201d and the fixed frame 201f to move. During the movement of the connecting plate 201d, the pulley 201e squeezes the bending plate 202c, and the bending plate 202c drives the L-shaped frame 202a to approach the support plate 101, until the L-shaped frame 202a drives the rubber sheet 202b to clamp the metallographic grinder and polisher. When the pulley 201e slides to the central depression of the bending plate 202c, the clamping piece is in a fixed state.

[0038] In addition, during the sliding of the fixed frame 201f, the second pulley 201g squeezes the side of the curved rod 203c. After being squeezed, the curved rod 203c slides on the side of the support plate 101 and also drives the swing rod 203b to approach the top rod 203d until the two are abutted. Then the swing rod 203b squeezes the fixed frame 203a with the top rod 203d as a fulcrum. Under the action of the fixed frames 203a on the upper and lower sides of the support plate 101, the L-shaped frame 202a is closer to the metallographic grinder and polisher, thereby increasing the clamping force of the L-shaped frame 202a, ensuring that the protective cover is firmly connected to the metallographic grinder and polisher through the fixing mechanism.

[0039] Example 3, reference Figure 5 to Figure 7 , which is the third embodiment of the utility model, further provides a metallographic grinding and polishing machine protective cover. It includes a guide rail mechanism; and,

[0040] The protection component 300 includes a transparent shell 301, which is made of an acrylic plate to facilitate staff to observe the inside of the protective cover, a lifting member 302 arranged on the side of the transparent shell 301, and an operating member 303 arranged on one side of the transparent shell 301; the inner side of the transparent shell 301 is slidably arranged on the inner wall of the clamping groove 103b, and the transparent shell 301 can slide up and down on the side of the T-rail 102 through the slider 103a.

[0041] The lifting member 302 includes a stop plate 302a, a limiting rod 302b and a spring 302c. The stop plate 302a is slidably arranged on the side of the transparent shell 301. The limiting rod 302b is fixedly arranged on the side of the stop plate 302a and slidably arranged on the inner side of the transparent shell 301 through an ear plate. The two ends of the spring 302c are respectively fixedly arranged on the side of the limiting rod 302b and one side of the ear plate.

[0042] The operating member 303 includes an operating port 303a, a movable plate 303b, an operating hole 303c, a cover plate 303d and a silicone corrugated plate 303e. The operating port 303a is opened on the side of the transparent frame, the movable plate 303b is slidably set on the inner side of the operating port 303a, the operating port 303a is opened on the side of the movable plate 303b, the cover plate 303d is slidably set on the inner wall of the operating hole 303c, and a plurality of silicone corrugated plates 303e are provided and are respectively fixed on the inner wall of the operating port 303a and the side of the movable plate 303b.

[0043] Usage process: After fixing the guide rail mechanism, remove the slider 103a and clamp it on the inner side of the transparent shell 301, then slide the slider 103a into the T-rail 102. After sliding the transparent shell 301 along the slide rail to a suitable height, rotate the cam 103c through the lever 103d to fix the slider 103a on the side of the T-rail 102.

[0044] In the process of lifting and sliding the transparent shell 301, the limit rod 302b is squeezed by the spring 302c, which always drives the abutment plate 302a to abut against the metallographic grinder and polisher, thereby fully protecting the staff. In addition, if the staff needs to use the metallographic grinder and polisher, the cover of the transparent shell 301 can be opened to install polishing paper, etc. When polishing the metal sample, the transparent shell 301 is closed again, and then the cover plate 303d is opened. The staff's hands can be extended into the interior of the transparent shell 301 through the operating hole 303c. During the operation, the staff's arms can squeeze the moving plate 303b, and the moving plate 303b can move along the inner wall of the operating port 303a. During the movement of the moving plate 303b, the silicone corrugated plate 303e is moved and can always protect the staff.

[0045] By squeezing the movable plate 303b, the positions of the worker's hands can be changed, so that the worker can adjust his hands in time according to his operating habits.
