The inner wall of locking block 502 is slidably connected to a movable rod 503. The top of movable rod 503 is fixedly connected to a push block 504. The front of push block 504 extends through to the front of horizontal block 501. The front of locking block 502 is provided with a positioning block 505.

[0018] refer to Figure 3 The limiting component 6 includes a gear 601 located inside the support block 4. The inner wall of the gear 601 is slidably connected to the inner wall of the support block 4 via a second rotating shaft. The top and bottom of the gear 601 are meshed with toothed plates 602. The toothed plates 602 extend from the side near the arc-shaped block 3 to the outside of the support block 4 and are fixedly connected to the surface of the arc-shaped block 3.

[0019] As a technical optimization of this utility model, the position of the arc-shaped block 3 can be limited by the setting of the limiting component 6, so as to prevent the arc-shaped block 3 from detaching from the support block 4.

[0020] refer to Figure 4 Vertical blocks 7 are fixedly connected to both sides of the bottom of the inner wall of the support block 4. The bottom of the horizontal block 501 has a vertical hole 8 that cooperates with the vertical block 7, and the surface of the vertical block 7 has a positioning groove 9 that cooperates with the positioning block 505. As a technical optimization of this utility model, the vertical block 7 and the vertical hole 8 can limit the position of the support block 4, and the positioning groove 9 can position the arc block 3, preventing the arc block 3 from moving when it is not needed.

[0021] refer to Figure 3 Limiting rods 10 are provided at the top and bottom of the support block 4. The side of the limiting rod 10 near the arc block 3 extends through to the front side of the support block 4 and is fixedly connected to the surface of the arc block 3. Limiting blocks 11 that cooperate with the arc block 3 are fixedly connected to both sides of the top of the detection device 1.

[0022] As a technical optimization of this utility model, the position of the arc-shaped block 3 can be limited by the setting of the limiting rod 10 to prevent the arc-shaped block 3 from detaching from the support block 4, and the position of the arc-shaped block 3 can be limited by the setting of the limiting block 11.

[0023] refer to Figure 4Both sides of the top of the push block 504 are movably connected to the spring piece 12 via the third pivot, and the rear side of the bottom of the spring piece 12 is movably connected to the inner wall of the horizontal block 501 via the fourth pivot.

[0025] refer to Figure 2 A rubber pad 13 is fixedly connected to the surface of the arc-shaped block 3, and a slot 14 for use with the card block 502 is opened on the back of the positioning block 505.

[0026] As a technical optimization of this utility model, the rubber pad 13 can increase the protective effect of the arc block 3 on the detection device 1, and the slot 14 can be used to position the arc block 3.

[0027] The working principle and usage process of this utility model are as follows: When in use, the user pushes the push block 504 backward, and the push block 504 moves backward, causing the movable rod 503 to move backward. The movable rod 503 moves backward, pushing the locking block 502 to rotate inward around the first rotating axis. The locking block 502 rotates and compresses the spring 12, causing the locking block 502 to disengage from the locking groove 14. Then, the user pulls the arc-shaped block 3 outward, causing the arc-shaped block 3 to disengage from the limiting block 11, and at the same time, causing the positioning block 505 to disengage from the positioning groove 9. Then, the user pulls the detection device 1 upward, causing the vertical block 7 to disengage from the vertical hole 8, and causing the detection device 1 to disengage from the arc-shaped block 3 and the support block 4. At this time, the detection device 1 can be disassembled. When protecting, the operation is reversed, and the detection device 1 can be protected by the support block 4 and the arc-shaped block 3.

[0028] In summary, this strength testing device for building concrete materials uses positioning component 5 to position the arc-shaped block 3 and support block 4, allowing the arc-shaped block 3 and support block 4 to be removed from the testing device 1 for protection. This solves the problem that the strength testing device cannot be protected during use, and is easily damaged by external impacts and compression, which affects the normal operation of the strength testing device.
