With the above structure, if the lower pressing block 44 moves to the right of the contact block 39 due to misoperation, when the contact block 39 needs to move reversely, the lower pressing block 44 can be utilized to push the right of the contact block 39, so that the contact block 39 rotates around the rotating seat 47, the lower pressing block 44 is avoided, and then the contact block 39 returns again under the gravity of the contact block 39 and the attraction of the magnet 48, so that the next work is facilitated.

The working principle of the invention is as follows: during operation, the first threaded rod 7 is driven to rotate by the moving motor 6, so that the moving seat 8 drives the impact test mechanism 9 to move, the distance between the impact test mechanism 9 and the first support 2 is adjusted, the impact test requirements of wallboards with different thicknesses are met, then the first lower clamping seat 11 is driven to rotate by the overturning motor 10, the arc-shaped baffle 13 is rotated to a horizontal position, the wallboard is placed above the first lower clamping seat 11 and the second lower clamping seat 18, the lower end of the wallboard is simultaneously abutted against the L-shaped plate 15, the lower end of the wallboard is supported by the transverse part of the L-shaped plate 15, the side face of the wallboard is limited by the vertical part of the L-shaped plate 15, the wallboard cannot slide and displace in the process of erecting the wallboard, the overturning motor 10 is then driven to rotate reversely, so that the wallboard is erected gradually and after being erected, the electric telescopic rod 16 is started to make the positioning block 17 descend, so that the positioning block 17 is used for abutting against and positioning the first upper clamping seat 12, then the hydraulic cylinder 5 is driven, the hydraulic cylinder 5 drives the second support 3 to move towards the first support 2, so that the first lower clamping seat 11 and the second lower clamping seat 18 are used for clamping the lower part of the wallboard, meanwhile, the first upper clamping seat 12 and the second upper clamping seat are used for clamping the upper part of the wallboard, at the moment, the first arc-shaped material guide seat 14 and the second arc-shaped material guide seat 19 are respectively abutted against the two sides of the wallboard, then the driving motor 29 rotates to drive the second threaded rod 30 to rotate, the second threaded rod 30 drives the sliding seat 31 to move, the sliding seat 31 drives the driving block 43 to move through the lifting seat 42, the driving block 43 is abutted against the stop block 38, so as to push the stop block 38, the impact head 37 is driven to move, when the pressing block 44 is contacted with the contact block 39, under the action of the second inclined plane, make briquetting 44 move down, thereby make lift seat 42 descend, lift seat 42 drives drive block 43 and descends, thereby make dog 38 break away from with drive block 43, this moment under elastic component's elasticity, strike head 37 and carry out the impact test to the wallboard, when needing to strike once more, driving motor 29 reverses, drive slide 31 reverse motion, after drive block 43 and dog 38 contact, under the effect of first inclined plane, make drive block 43 descend, thereby make drive block 43 move the left side of dog 38, be convenient for drive dog 38 next time, when the impact test, if the wallboard is cracked, the piece can fall down on first arc guide seat 14 and second arc guide seat 19, slide to both ends under the cambered surface guide of first arc guide seat 14 and second arc guide seat 19, thereby fall into baffle 4, send the crushed aggregates into outside material receiving box or directly fall to ground through baffle 4, thereby can realize collecting the wallboard piece, prevent that the piece from influencing the work of device, thereby arc support and second arc guide seat 13's the support, the convenience of splashing can be improved to the piece collection after the baffle structure sets up.

According to the difference of the impact dynamics that needs, it is rotatory to utilize rotatory handle 36 to drive swivel column 35, swivel column 35 drives threaded column 46 rotatory, thereby make the regulation post 32 remove, make contact block 39 be located different positions, because briquetting 44 contacts the back with contact block 39 down, impact head 37 will kick-back and strike, so contact block 39 and the distance between briquetting 44 down, be exactly to elastic component's compressive capacity, thereby realize the experimental demand of different impact dynamics, cooperation actuating mechanism, make no matter what to elastic component's compressive capacity, can all realize impacting head 37's automatic return, full automation degree is high, and the dynamics of control impact that can be accurate, improve the shock resistance test's rate of accuracy.

In conclusion, through the arrangement of the structures such as the first arc-shaped material guide seat 14, the second arc-shaped material guide seat 19 and the material guide groove 4, the wall plate fragments are collected, and the function of preventing the fragments from influencing the operation of the device is realized.

The specific embodiments described herein are merely illustrative of the spirit of the invention.
