The cement block 6 is first placed on the top of the base 1 and placed directly below the pressure block 5. The hydraulic cylinder 4 is then started to drive the pressure block 5 to move downward, and the pressure block 5 is used to squeeze the cement block 6 to detect its strength. An inclined groove 7 is provided on the inner wall of the base 1. A protective mechanism 8 is provided on the base 1 to prevent the crushed cement fragments from splashing. By setting the protective mechanism 8, the crushed cement fragments can be blocked to prevent the cement fragments from splashing and accidentally injuring the staff. A positioning mechanism 9 is provided on the base 1 to position the cement block 6. By setting the positioning mechanism 9, the cement block 6 can be positioned to avoid displacement during the extrusion detection process and improve the stability of the cement block 6 during detection.

[0022] The protective mechanism 8 comprises a protective cover 81, a swing rod 82, a limit groove 83, a limit rod 84, a pedal 85 and a torsion spring 86; the protective cover 81 is slidably connected to the outer wall of the base 1, and a limit groove 83 is provided on the protective cover 81. When the limit rod 84 moves along the inner wall of the limit groove 83 and presses the protective cover 81 upward, the protective cover 81 can slide upward on the outer wall of the base 1 and protrude from the top of the base 1. At this time, the protective cover 81 can be used to block the periphery of the cement block 6, and the protective cover 81 can be used to block the crushed cement fragments to prevent the cement fragments from flying. In order to avoid accidental splashing and injuring staff, the middle part of the swing arm 82 is hinged on the outer wall of the base 1, and a torsion spring 86 is arranged at the hinge between the swing arm 82 and the base 1. A limit rod 84 is fixedly installed on one end of the swing arm 82, and the outer wall of the limit rod 84 is in contact with the inner wall of the limit groove 83. A pedal 85 is hinged on the other end of the swing arm 82. Stepping on the pedal 85 can drive the swing arm 82 to rotate and compress the torsion spring 86. At the same time, the swing arm 82 will drive the limit rod 84 to rotate upward with the torsion spring 86 as the center. At this time, the limit rod 84 will move in contact with the inner wall of the limit groove 83 and squeeze the protective cover 81 upward.

[0023] The positioning mechanism 9 includes a slide bar 91, a positioning bar 92, a positioning block 93, a side plate 94, and a spring 95; the slide bar 91 is slidably connected to the inner wall of the inclined groove 7, the inner wall of the slide bar 91 is slidably connected with the positioning bar 92, and the positioning bar 92 penetrates the slide bar 91, and the positioning bar 92 moves upward while pulling the slide bar 91 upward, so that the slide bar 91 slides upward on the inner wall of the inclined groove 7 and gradually approaches the cement block 6, one end of the positioning bar 92 is fixedly installed with the positioning block 93, and the other end of the positioning bar 92 penetrates the protective cover 81 A side plate 94 is fixedly installed, and the positioning rod 92 is fitted with the penetration point of the protective cover 81. When the protective cover 81 moves upward, it will drive the positioning rod 92 to move upward synchronously. A spring 95 is fixedly installed on the side wall of the side plate 94. The end of the spring 95 away from the side plate 94 is fixedly installed on the side wall of the slide bar 91. The slide bar 91 gradually approaches the cement block 6 and cooperates with the positioning rod 92, the positioning block 93, the side plate 94, and the spring 95 to clamp the cement block 6 to avoid displacement during the extrusion detection process.

[0024] Working principle: first place the cement block 6 on the top of the base 1 and directly below the pressing block 5, then step on the pedal 85 with your foot to drive the rocker arm 82 to rotate and compress the torsion spring 86. At the same time, the rocker arm 82 will drive the limit rod 84 to rotate upward with the torsion spring 86 as the center. At this time, the limit rod 84 will move in contact with the inner wall of the limit groove 83 and squeeze the protective cover 81 upward, so that the protective cover 81 can slide upward on the outer wall of the base 1 and protrude from the top of the base 1. At this time, the protective cover 81 can be used to block the outer periphery of the cement block 6, and then start the hydraulic cylinder 4 to drive the pressing block 5 to move downward, and use the pressing block 5 to squeeze the cement block 6 to test its strength. At the same time, the protruding protective cover 81 can be used to block the crushed cement fragments to prevent the cement fragments from splashing and accidentally injuring the staff.

[0025] When the protective cover 81 moves upward, it will drive the positioning rod 92 to move upward synchronously. At the same time, the positioning rod 92 will pull the sliding rod 91 upward, so that the sliding rod 91 slides upward on the inner wall of the inclined groove 7 and gradually approaches the cement block 6. At the same time, the sliding rod 91 will drive the positioning rod 92 and the positioning block 93 to gradually approach the cement block 6. When the positioning block 93 is attached to the side wall of the cement block 6 and the sliding rod 91 continues to slide, the sliding rod 91 will continue to approach the cement block 6, and the positioning block 93 will be tightly attached to the side wall of the cement block 6. Therefore, at this time, the sliding rod 91 will stretch the spring 95, and the side plate 94 can be pulled by the elasticity of the spring 95. At the same time, the positioning rod 92 can drive the positioning block 93 to be tightly attached to the side wall of the cement block 6. The cement block 6 can be positioned by cooperating with the positioning rod 92 and the positioning block 93 to avoid displacement during the extrusion detection process and improve the stability of the cement block 6 during detection.

[0026] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
