The limiting mechanism 4 is located between the bottom of the inner wall of the installation box 1 and the bottom of the support plate 3. An adjusting mechanism 5 for adjusting the position of the limiting mechanism 4 is arranged between the limiting mechanism 4 and the installation box 1. The adjusting mechanism 5 includes an adjusting rod 51, one end of the adjusting rod 51 is rotatably connected to the movable box 41, and the end of the adjusting rod 51 away from the movable box 41 passes through the installation box 1 and extends to the outside of the installation box 1. The adjusting rod 51 is a threaded rod and the end located outside the installation box 1 is fixedly connected to an adjusting handwheel, and the adjusting rod 51 is threadedly connected to the installation box 1 through a threaded barrel 52. The threaded barrel 5 2 is fixedly connected to the installation box 1, an impact hammer 7 is arranged on the top of the installation box 1, the impact hammer 7 penetrates the installation box 1 and the connection box 61 and is slidably connected to the installation box 1 and the connection box 61, a driving mechanism 6 for adjusting the position of the impact hammer 7 is arranged between the impact hammer 7 and the installation box 1, the driving mechanism 6 includes a connection box 61, the connection box 61 is fixedly connected to the top of the installation box 1, a driving motor 62 is fixedly connected to one side of the connection box 61, the driving motor 62 has the function of forward and reverse rotation, and is connected to the control system and the power supply through a wire, the output end of the driving motor 62 is fixedly connected to a driving screw rod 63, the driving screw rod 63 penetrates the connection box 61 and extends to the inside of the connection box 61, the surface of the driving screw rod 63 is threadedly connected with a threaded tube 64, the threaded tube 64 is fixedly connected to the impact hammer 7 through a movable block 65, and the movable block 65 is slidably connected to the inner wall of the connection box 61.

[0023] Through the coordinated arrangement of the adjusting mechanism 5 and the driving mechanism 6, the adjusting mechanism 5 drives the distribution box to move laterally, and the driving mechanism 6 drives the impact hammer 7 to move forward and backward, so that the impact hammer 7 can fully cover the top surface of the distribution box, thereby facilitating impact testing of multiple points of the distribution box, effectively avoiding the randomness of the impact test results, and thus improving the accuracy of the test.

[0024] Figure 2 and 3 A second embodiment is shown, and its main difference from the first embodiment is that the limiting mechanism 4 includes a movable box 41, which is slidably connected to the bottom of the inner wall of the installation box 1, and one side of the inner wall of the movable box 41 is rotatably connected to a bidirectional threaded rod 42, one end of the bidirectional threaded rod 42 penetrates the movable box 41 and the installation box 1 and extends to the outside of the installation box 1, and one end of the bidirectional threaded rod 42 located outside the installation box 1 is fixedly connected to an adjusting handwheel, and a threaded sleeve 43 is threadedly connected to the surface of the bidirectional threaded rod 42, and a connecting block 44 is fixedly connected to the surface of the threaded sleeve 43, and the connecting block 44 penetrates the support plate 3 and extends to the top of the support plate 3, and one end of the connecting block 44 away from the threaded sleeve 43 is fixedly connected to a limiting plate 45.
