Then the worker can pull the handrail 5 provided on the inner side of the left end of the fixing sleeve 2 outward. Since the right side of the handrail 5 is fixedly connected with the limiting plate 4 which is engaged with the fixing sleeve 2, the upper and lower ends of the limiting plate 4 are engaged with the limiting rods 6 which are fixedly connected with the fixing sleeve 2, the right end of the limiting rods 6 is nested with the gasket 7 which is provided in close contact with the limiting plate 4, and the left end of the limiting rods 6 is nested with the spring 8 which is in close contact with the fixing sleeve 2 and the gasket 7. Therefore, by pulling the handrail 5 outward, the limiting plate 4 is engaged and limited by the fixing sleeve 2 and the limiting rods 6, and moves outward under the pressure of the spring 8 to disconnect the buckle connection between the limiting plate 4 and the receiving plate 3 which is nested with the right end of the fixing sleeve 2. Therefore, the worker can adjust the connection distance between the receiving plate 3 and the fixing sleeve 2 according to the height requirement of the drop ball impact test bench, and can loosen the pull of the handrail 5 after the adjustment is completed, so that the limiting plate 4 is buckled with the receiving plate 3 under the action of the spring 8, the receiving plate 3 is limited with the fixing sleeve 2, and the height adjustment of the drop ball impact test bench is completed.

[0029] The worker can first place the drop ball impact test bench in the position to be used, and then screw through the outer end of the base 1 to install and fix the drop ball impact test bench. Then the worker can pull the handrail 5 provided on the inner side of the left end of the fixing sleeve 2 outward. Since the right side of the handrail 5 is fixedly connected with the limiting plate 4 which is engaged with the fixing sleeve 2, the upper and lower ends of the limiting plate 4 are engaged with the limiting rods 6 which are fixedly connected with the fixing sleeve 2, the right end of the limiting rods 6 is nested with the gasket 7 which is provided in close contact with the limiting plate 4, and the left end of the limiting rods 6 is nested with the spring 8 which is in close contact with the fixing sleeve 2 and the gasket 7. Therefore, by pulling the handrail 5 outward, the limiting plate 4 is engaged and limited by the fixing sleeve 2 and the limiting rods 6, and moves outward under the pressure of the spring 8 to disconnect the buckle connection between the limiting plate 4 and the receiving plate 3 which is nested with the right end of the fixing sleeve 2. Therefore, the worker can adjust the connection distance between the receiving plate 3 and the fixing sleeve 2 according to the height requirement of the drop ball impact test bench, and can loosen the pull of the handrail 5 after the adjustment is completed, so that the limiting plate 4 is buckled with the receiving plate 3 under the action of the spring 8, the receiving plate 3 is limited with the fixing sleeve 2, and the height adjustment of the drop ball impact test bench is completed.
