The mounting block 406 is located on the inner side of the mounting frame 401. The outer surfaces of both sides of the mounting frame 401 are respectively fixedly connected with second fixed shafts 407. The outer surfaces of the two second fixed shafts 407 rotate and penetrate the inner surfaces of both sides of the mounting frame 401. The inner surface of the mounting block 406 is provided with a rebound tester body 408. 1 is fixedly connected to a limiting block 402 on the front surface thereof, the limiting block 402 is matched with a mounting block 406, a fixing hole 410 is provided on an outer surface of one side of the mounting block 406, a bolt 403 is threadedly connected to an inner surface of the fixing hole 410, a first through hole 404 is provided on an outer surface of one side of the mounting frame 401 near the front surface, a second through hole 405 is provided on an outer surface of one side of the mounting frame 401 near the top, and both the first through hole 404 and the second through hole 405 match the position of the fixing hole 410.

[0024] The effect achieved by the entire embodiment 1 is that when testing a high concrete wall, firstly, the fixed posture of the rebound tester body 408 is adjusted according to the test direction of the concrete wall or concrete roof. The initial position of the rebound tester body 408 is vertically upward. The fixed posture for testing the concrete roof surface is that the bolt 403 is inserted into the second through hole 405 and connected with the thread of the fixing hole 410. When the concrete wall needs to be tested, the bolt 403 is held and screwed outward to make it engage with the mounting block 410. 06, and pull the bolt 403 out of the second through hole 405, rotate the mounting block 406, and the mounting block 406 will be rotated 90 degrees counterclockwise in the mounting frame 401 to the limit block 402 with the two second fixed shafts 407 as the axis.

When the fixing hole 410 coincides with the second through hole 405, the rebound tester body 408 is perpendicular to the roof surface. At this time, the concrete roof surface can be inspected after being fixed by the bolt 403. When the fixing hole 410 coincides with the first through hole 404, the rebound tester body 408 fixed in the mounting block 406 is perpendicular to the wall surface. After inserting the bolt 403 into the first through hole 404 and the fixing hole 410 and twisting it, the rebound tester body 408 can be fixed, and the opening device in the rebound tester body 408 is opened to make its firing end pop out, and the self-locking motor 307 is started. When the output end of the self-locking motor 307 drives the first fixed shaft 305 to rotate clockwise in the fixed frame 306, the active gear 304 will drive the extension rod 302 to move up when it meshes and rotates with the gear block 303. When the extension rod 302 moves up to a certain height in the fixed cylinder 301, the self-locking motor 307 stops running and locks the output end, so that the firing end of the rebound tester body 408 stays in the tested concrete wall area, and then pushes the handrail set on the top side of the base plate 1 to make the firing end of the rebound tester body 408 hit the concrete wall for testing, avoiding the need for staff to hold the operation in the air when testing the concrete wall at a higher place, thereby improving the use effect of the concrete structure detection device for construction project quality supervision.
