The clamping mechanism includes two horizontal plates 20 movably disposed in the inner cavity 11 and arranged vertically at intervals. The top of one of the horizontal plates 20 is fixedly connected to the output end of the tensile sensor 12. The two horizontal plates 20 each have a protrusion 21 on one side facing each other, and the two protrusions 21 each have symmetrically arranged grooves 2 on one side facing each other. 2. A groove 221 is recessed on the inner side wall of the groove 22. A first lead screw 23 is rotatably installed in each groove 221, and a rod sleeve 24 is slidably embedded in each groove 221. One end of the rod sleeve 24 extends into the groove 22 and is fixedly connected to a movable plate 241. The other end of the rod sleeve 24 is fitted onto one end of the first lead screw 23. The driving mechanism includes a rotating shaft 31 that is vertically rotatably inserted into the inner cavity 11. The rotating shaft 31 is used to drive the two first lead screws 23 to rotate. The lifting mechanism is set in the inner cavity 11 and is used to drive the other horizontal plate 20 to move up and down.

[0028] In this embodiment, the protrusion 21 is rotatably mounted on a bushing 25, the bushing 25 is slidably mounted on the rotating shaft 31 and can rotate with the rotating shaft 31, the outer wall of the bushing 25 is fixedly mounted on a first bevel gear 51, and the outer wall of the other end of the first lead screw 23 is fixedly mounted on a second bevel gear 52 that meshes with the first bevel gear 51.

[0029] In this embodiment, the lifting mechanism includes two second lead screws 41 rotatably inserted into the inner cavity 11. The upper and lower ends of the second lead screws 41 have smooth rod sections and threaded rod sections, respectively. The two ends of one horizontal plate 20 are slidably sleeved on the smooth rod sections of the two second lead screws 41, and the two ends of the other horizontal plate 20 are respectively fitted on the threaded rod sections of the two second lead screws 41. The two second lead screws 41 are connected by a transmission assembly.

[0030] In this embodiment, the transmission assembly includes pulleys 61 fixedly disposed at the bottom of the two second lead screws 41, and a transmission belt 62 wound around the two pulleys 61.

[0031] In this embodiment, the lifting mechanism further includes a second motor 42 fixedly disposed on the top of the box body 10, and the output end of the second motor 42 is connected to one of the second lead screws 41 for transmission.

[0034] The specific implementation process is as follows:

[0035] Before the test begins, the lifting mechanism is driven to move the other horizontal plate 20 up and down to a suitable position. Then, the building material sample is placed into the inner cavity 11, so that the upper and lower ends of the building material sample are respectively located in the two grooves 22, and the building material sample is located between the movable plate 241 and the other inner wall of the groove 22. The rotating shaft 31 is driven to drive the two first lead screws 23 to rotate. Because the slide groove 221 restricts the rotation of the sleeve 24, the sleeve 24 moves towards the building material sample as the first lead screw 23 rotates, until the movable plate 241 and the other inner wall of the groove 22 press the building material sample tightly. Then, the lifting mechanism is driven to lower the other horizontal plate 20, thereby stretching the building material sample. At the same time, the reading of the tension sensor 12 is observed to detect the tensile strength of the building material sample.

[0036] The second motor 42 drives one of the second lead screws 41 to rotate. Because the transmission belt 62 is wrapped around the pulleys 61 at the bottom of the two second lead screws 41, it drives the other second lead screw 41 to rotate. Because the two ends of the other horizontal plate 20 are respectively fitted onto the threaded sections of the two second lead screws 41, the other horizontal plate 20 moves up and down as the second lead screw 41 rotates.
