When concrete dust adheres to the interior of the transparent protective cover 34, the pull rod 334 is pulled, and the pull rod 334 drives the fixing block 333 to move and compress the fixing spring 335, so that the fixing block 333 disengages from the square plug block 332, and then the square plug block 332 can be separated from the disassembly seat 331, so that the transparent protective cover 34 fixed to the square plug block 332 can be removed for cleaning, so that the device can conveniently protect the workbench 1 when in use to prevent debris from splashing, and the structure is practical and the setting cost is low.

[0032] Example 2

[0033] The difference between this embodiment and embodiment 1 is that: specifically, the adjustment component 6 includes an adjustment seat 61, a bidirectional trapezoidal screw 62, a rotating block 63, a square slider 64 and an adjustment block 65, wherein an adjustment seat 61 is provided on one side of the support frame 4, a bidirectional trapezoidal screw 62 is provided inside the adjustment seat 61, a rotating block 63 is provided at one end of the bidirectional trapezoidal screw 62, the surface of the bidirectional trapezoidal screw 62 is symmetrical and is threadedly connected to the square slider 64, and an adjustment block 65 is provided at one end of the square slider 64.

[0034] By adopting the above technical solution, the rotating block 63 is rotated, and the rotation of the rotating block 63 will drive the bidirectional trapezoidal screw 62 to rotate, and the rotation of the bidirectional trapezoidal screw 62 will drive the square slider 64 to move, and the movement of the square slider 64 will drive the adjustment block 65 to move, thereby adjusting the position of the clamping assembly 7. When the device is in use, the position of the clamping assembly 7 can be easily adjusted without the need for step-by-step operation, thereby improving the convenience of use.

[0035] Specifically, the surface of the rotating block 63 is covered with an anti-slip sleeve, and corrugated dust-proof tubes 66 are provided on both sides of the square slider 64 , and the corrugated dust-proof tubes 66 are covered on the surface of the bidirectional trapezoidal screw 62 .

The setting of the anti-slip sleeve makes it easy to rotate the rotating block 63, and the setting of the corrugated dust-proof tube 66 makes it easy to prevent dust from adhering to the bidirectional trapezoidal screw 62, so that the position of the clamping assembly 7 can be easily adjusted when the device is in use, without the need for step-by-step operation, thereby improving the convenience of use.

[0038] The structure and use principle of the hardness detection component 5 and the clamping component 7 in the utility model have been disclosed in a hardness detection device for building concrete disclosed in Chinese patent application No. 201921883698.0. Its working principle is to place the concrete slab in the inner cavity of the U-shaped block, rotate the turntable to drive the threaded rod to rotate, and thread the threaded rod to be threadedly connected to the first threaded hole through the threaded rod, so that the threaded rod drives the clamping plate to move downward, and the clamping plate presses the concrete slab. The controller controls the first electric telescopic rod to extend to drive the pressure sensor and the pressure plate to move downward, and the pressure plate pushes the concrete slab until it breaks. The pressure sensor sends the detected pressure to the controller, and the controller controls the display screen to display the pressure data.

[0039] The working principle and use process of the utility model are as follows: The utility model is used to test the hardness of building concrete. When in use, the position of the clamping component 7 is adjusted by the adjusting component 6, and then the concrete plate is clamped and fixed by the clamping component 7. Then the protective component 3 is closed, and the hardness detection component 5 can be used for detection. When the protective component 3 is used, the transparent protective cover 34 is pushed down. When the transparent protective cover 34 moves down, it will drive the damping slider 32 to slide on the damping slide rod 35, and at the same time compress the reset spring 36. When the damping slider 32 and the clamping rod 37 are in contact, the damping slider 32 and the clamping rod 37 are in contact. When the transparent protective cover 34 needs to be opened, the clamping rod 37 is pulled out of the clamping hole, and the reset spring 36 is then reset, driving the damping slider 32 to move up slowly, so that the transparent protective cover 34 is closed. The transparent protective cover 34 is automatically opened. When concrete dust adheres to the inside of the transparent protective cover 34, the pull rod 334 is pulled, and the pull rod 334 drives the fixing block 333 to move and compress the fixing spring 335, so that the fixing block 333 is separated from the square plug block 332. Then, the square plug block 332 can be separated from the disassembly seat 331, so that the transparent protective cover 34 fixed to the square plug block 332 can be removed for cleaning. When the device is in use, it can conveniently protect the workbench 1 from debris splashing. The structure is practical and the setting cost is low. When the adjustment component 6 is used, Rotate the rotating block 63, and the rotation of the rotating block 63 will drive the bidirectional trapezoidal screw 62 to rotate. The rotation of the bidirectional trapezoidal screw 62 will drive the square slider 64 to move. The movement of the square slider 64 will drive the adjustment block 65 to move, thereby adjusting the position of the clamping assembly 7. The setting of the anti-slip sleeve makes it easy to rotate the rotating block 63. The setting of the corrugated dust-proof tube 66 makes it easy to prevent dust from adhering to the bidirectional trapezoidal screw 62, so that the position of the clamping assembly 7 can be easily adjusted when the device is in use. There is no need to operate in steps, which improves the convenience of use.
