A pressing block 26 is connected to the end of the fifth telescopic member 25. A pressure gauge 28 is installed on the fifth telescopic member 25. A control box 7 is installed on the outer wall of the base 6. All functional drive components and detection components are connected to the control box 7 by wiring.
[0019] Please see Figure 2The driven gear 11 is installed on the lower outer wall of the rotating sleeve 10, the driving component 13 is installed on the inner bottom surface of the base 6, and the driving gear 14 is installed on the top output end of the driving component 13. The driven gear 11 is meshed with the driving gear 14.
[0020] Please see Figures 2 to 4 The top of the turntable 9 is fitted with a first mounting sleeve 20. The third telescopic member 21 is detachably mounted inside the first mounting sleeve 20. The top of the fourth telescopic member 23 is fitted with a second mounting sleeve 24. A fifth telescopic member 25 is detachably mounted inside the second mounting sleeve 24.

[0021] Example 2: See Figure 1 Based on Embodiment 1, the steel fastener includes a standard part 1, conversion parts 2 installed at both ends of the standard part 1, corner bolts 4 installed at the ends of the two conversion parts 2 that are far apart from each other, and a connector 3. The connector 3 is used to enhance the connection stability between the conversion parts 2 and the standard part 1. The connection and fixation between the components are achieved by high-strength bolts 5.
[0022] Please see Figure 2 Anti-slip pads 19 are installed on the top of the placement plate 16 and the bottom of the upper clamping plate 18. The anti-slip pads 19 are made of rubber.
[0023] Working Principle: Taking standard part 1 as an example, a strength test is performed on a single steel fastener component. Standard part 1 is placed on the placement plate 16. The height of standard part 1 is adjusted by the first telescopic member 15. The upper clamping plate 18 is moved down by the second telescopic member 17. The upper clamping plate 18 cooperates with the placement plate 16 to clamp standard part 1. The horizontal position of the slider 22 is adjusted by the extension or shortening of the third telescopic member 21. The height of the fifth telescopic member 25 is adjusted by the extension or shortening of the fourth telescopic member 23, so that the pressing block 26 is located on the side of standard part 1. The extension of the fifth telescopic member 25 moves the pressing block 26 closer to the outer wall of standard part 1. The end of one pressing block 26 abuts against one side of the outer wall of standard part 1, while the other pressing block 26 continuously applies pressure to the other side of the outer wall of standard part 1. The pressure value is controlled by the pressure gauge 28, so that the load of one pressing block 26 is reduced from 0 kN. After increasing the load from 0kN / m² to 30kN / m² and then unloading, the load is increased again from 0kN / m² to 60kN / m² and held for two minutes. If no part of the standard component 1 is damaged, the strength test is qualified. The same method is used to test the conversion component 2 and the corner bolt 4. When testing the high-strength bolt 5, the connected steel fastener is placed on the placement plate 16, and the positions of the two compression blocks 26 are adjusted so that the right-angle groove 29 of one compression block 26 is aligned with the bottom corner of one end of the standard component 1, and the right-angle groove 29 of the other compression block 26 is aligned with the bottom corner of one end of the conversion component 2. Then pressure is applied so that the load of one compression block 26 is increased from 0kN / m² to 65kN / m² and then unloaded. The load is increased again from 0kN / m² to 135kN / m² and held for two minutes. If the connection between the standard component 1 and the conversion component 2 is not damaged, the strength test is qualified. The actual pressure value during the test can be adjusted according to the test requirements.
