Embodiment two:

[0024] The moving component 5 comprises lifting frames 501 which are slidingly installed in the accommodation grooves 4031, the top of the lifting frames 501 is provided with accommodation grooves 502, the inside of the accommodation grooves 502 is rotatably installed with lifting rollers 503, the bottom of the lifting frames 501 is fixedly installed with two lifting strips 504 which are distributed in front and back, the bottom of the left and right lifting strips 504 is commonly connected with a cantilever plate 505, the middle part of the cantilever plate 505 is rotatably installed with a guide wheel 506, the back of the left bearing table 401 and the right bearing table 402 is fixedly installed with a stepping motor 507, the inside of the left bearing table 401 and the right bearing table 402 is rotatably installed with a torsion bar 508, the position of the stepping motor 507 corresponds to the position of the torsion bar 508, and the output shaft end of the stepping motor 507 is fixedly connected with one end of the torsion bar 508, the outer wall of the torsion bar 508 is fixedly installed with a lifting disc 509, the outer wall of the lifting disc 509 is provided with an arc groove 5009, the guide wheel 506 is located in the arc groove 5009, the end of the torsion bar 508 away from the stepping motor 507 is fixedly installed with an incomplete gear 5012, the top of the detection table 2 is fixedly installed with a straight rack 5013, the straight rack 5013 is located at the bottom of the incomplete gear 5012, and the specification of the incomplete gear 5012 is matched with the specification of the straight rack 5013, the right side of the left bearing table 401 is provided with a switching hole 404, and the inside of the switching hole 404 is rotatably provided with a locking component 6. The locking component 6 comprises a torsion bar 601 which is rotatably installed in the switching hole 404, the torsion bar 601 penetrates through the switching hole 404 and extends into the inside of the left bearing table 401, one end of the torsion bar 601 located in the inside of the left bearing table 401 is fixedly installed with a driven bevel gear 602, one of the lifting discs 509 located at the same side of the left bearing table 401 is fixedly installed with a driving bevel gear 603 in the front, the driving bevel gear 603 is matched with the driven bevel gear 602, the end of the torsion bar 601 away from the driven bevel gear 602 is fixedly installed with a lock tongue 604, the specification and position of the lock tongue 604 is matched with the specification and position of the insertion groove 4002 and the locking groove 4003. Specifically, before testing, the two stepping motors 507 are started, the two stepping motors 507 rotate to drive the two incomplete gears 5012 to rotate through the two torsion bars 508, the two incomplete gears 5012 roll along the straight rack 5013 to drive the left bearing table 401 and the right bearing table 402 to move to the middle at a constant speed, until the left bearing table 401 and the right bearing table 402 are combined, so that the left bearing table 401 drives the lock tongue 604 to move, until the lock tongue 604 penetrates through the insertion groove 4002 and inserts into the inside of the locking groove 4003, the toothless part of the two incomplete gears 5012 is just rotated to the lowermost, so as to release the engagement with the straight rack 5013 (as shown in FIG. 10B). Figure 2(As shown in the state), then the stepper motor 507 drives the torsion bar 508 to continue rotating the lifting disk 509 by a certain angle, so that the guide wheel 506 is placed inside the arc groove 5009. During this period, the lifting disk 509 drives the active bevel rack 603 to rotate and mesh with the driven bevel gear 602, and drives the driven bevel gear 602 to rotate. The rotation of the driven bevel gear 602 drives the locking tongue 604 to rotate 90° through the torsion bar 601, thereby forming a locking action with the slot 4002, firmly locking the left support platform 401 and the right support platform 402 together. Thus, when the metal building material board is subjected to pressure resistance testing, the left support platform 401 and the right support platform 402 will not separate, ensuring the stability of the test. When performing a bending resistance test on the metal building material panel, the two stepper motors 507 are started in reverse. The output shafts of the two stepper motors 507 drive the two incomplete gears 5012 in reverse via two torque rods 508. Since the missing teeth of the two incomplete gears 5012 are located at the bottom, the incomplete gears 5012 do not mesh with the top of the rack 5013 at the beginning of the reverse rotation. During this period, the torque rods 508 drive the lifting disc 509 and the driving bevel rack 603 to rotate. The rotation of the lifting disc 509 pushes the guide wheel 506 located inside the arc groove 5009 upward. The upward movement of the guide wheel 506 drives the lifting frame 501 upward via the lifting plate 505 and the lifting bar 504. 1. The upward movement drives the lifting roller 503 to move upward, which lifts the metal building material plate located on top of the bearing plate 403 upward, separating its bottom from the top of the bearing plate 403, until the incomplete gear 5012 just rotates to mesh with the rack 5013. Under the rotation of the incomplete gear 5012, the left bearing platform 401 and the right bearing platform 402 move to both sides. During this process, because the lifting roller 503 lifts the metal building material plate upward, the top of the bearing plate 403 will not rub against the bottom of the metal building material plate when the left bearing platform 401 and the right bearing platform 402 move to both sides, further improving the protection effect on the device and the metal building material plate.

[0025] Furthermore, the bottom wall of the storage groove 4031 is provided with two guide grooves 4032 distributed front and back. The outer wall of the lifting bar 504 is slidably connected to the inner wall of the guide groove 4032. By providing the guide groove 4032, the lifting bar 504 is guided, making the up and down movement of the lifting bar 504 more stable and smooth.

[0026] Further, the outer side middle part of the pick plate 505 is fixedly installed with a spring holder 5010, the top of the spring holder 5010 is fixedly installed with a second spring 5011, the top of the second spring 5011 is fixedly connected with the bottom of the bearing plate 403, when the lifting disc 509 pushes the guide wheel 506 to move upward, the guide wheel 506 drives the pick plate 505 to move upward together, drives the spring holder 5010 to move, causes the second spring 5011 to compress and store power, so that when the arc groove 5009 rotates again to the periphery of the guide wheel 506, the spring-back force of the second spring 5011 pushes the spring holder 5010, the pick plate 505 and the guide wheel 506 to move downward and reset, further drives the lifting strip 504, the lifting frame 501 and the lifting roller 503 to reset downward.

[0027] Further, the top of the lifting roller 503 is lower than the top of the bearing plate 403, because the lifting roller 503 is lower than the top of the bearing plate 403, when the top compression detection is carried out, the bottom of the metal building material plate will not contact with the top of the lifting roller 503, so that the metal building material plate placed on the top of the bearing plate 403 will not move left and right when the top compression detection is carried out. Example three:

[0028] The left side of the right bearing table 402 is provided with a slot 4002, the inside of the right bearing table 402 is provided with a locking groove 4003, the locking groove 4003 is located at the right end of the slot 4002, and the locking groove 4003 is communicated with the inside of the slot 4002, the bottom of the locking groove 4003 is provided with an expansion hole 4004, the inside of the expansion hole 4004 is slidably provided with a positioning part 7; The positioning part 7 comprises a top plate 701 slidably installed in the locking groove 4003, the bottom of the top plate 701 is fixedly installed with a latch 702, the latch 702 is slidably located in the inside of the expansion hole 4004 and extends to the bottom of the right bearing table 402, the periphery of the latch 702 is sleeved with a third spring 703, the third spring 703 is fixedly installed between the bottom of the top plate 701 and the bottom wall of the expansion hole 4004, the top of the detection table 2 is fixedly installed with a socket 704, the position of the socket 704 corresponds to the position of the latch 702, the bottom of the latch 702 is inserted into the inside of the socket 704; The embodiment is specifically, the driving bevel gear 602 rotates through the torsion bar 601 to drive the lock tongue 604 to rotate 90°, so as to form the locking effect with the slot 4002, and the left bearing table 401 and the right bearing table 402 are locked together. At the same time, the lock tongue 604 pushes the top plate 701 downward during the rotation in the locking groove 4003, and the top plate 701 drives the bolt 702 to move downward and insert into the inside of the socket 704, so as to position the right bearing table 402 on the top of the detection table 2, and the right bearing table 402 and the left bearing table 401 are locked, so as to further position the left bearing table 401 and the right bearing table 402, avoid the movement of the left bearing table 401 and the right bearing table 402, and make the left bearing table 401 and the right bearing table 402 not move left and right during the compression detection.

The embodiment is specifically, the output rod of the hydraulic cylinder 301 drives the pressure head 302 to move downward, and the pressure head 302 drives the two guide rods 303, the U-shaped frame 304 and the pressing plate 305 to move downward during the movement. Until the bottom of the pressing plate 305 abuts against the top of the metal building material plate, and with the continuous downward movement of the pressure head 302, the first spring 306 is gradually stretched and stored, and the two pressing plates 305 are further tightly abutted on the top of the metal building material plate under the elastic force of the first spring 306, so as to avoid the loosening of the metal building material plate.
