IV. Structure of the Child Car and Stool Impact Testing Machine： 
1.This machine adopts a frame structure and its surface is treated with high-temperature resistant enamel coating. 
2. The controller is operated via touch control. 
3. The test bench is constructed with steel structure. 
4. The impact principle employs a precision cylinder-type free-falling hammer. 
V. Precautions for the Child Car Seat Impact Testing Machine：
1.During the test, drainage should be carried out at any time to prevent damage to the cylinder's lifespan. 
2. During the test, the test personnel should keep observing on-site to prevent the detached parts from getting stuck in the transmission components, which could cause damage to the testing machine. If any abnormal phenomenon occurs during the test, the machine should be stopped immediately for inspection. 
3. When the machine is not in use, please turn off the main power supply. 
4. The instrument should be kept clean. Especially on the test table, it must not be damaged by impact and must not be contaminated. 
5. Please regularly add lubricating oil to the bearing housing to ensure the normal operation of the bearings. 
6. The lifting and lowering screw rod should be kept clean and regularly lubricated to maintain its condition. 
7. After each test is completed, please turn off all the switches and the power supply of the machine.
