Ask how to remove the metal clasp behind the rocker.... It is difficult to restore the pressure when the machine is opened. And that clip is very easy to break. The main thing is that when you open it, there is no dust at all. It's better to buy a domestic assembly and replace it with the one that will pop up in an instant. Try to change it directly in an open place, or scrap it directly Do not open the rocker. The opening process of the rocker is destructive, and it is difficult to install it back again. It needs gluing seriously. moreover, even if it is installed, the center may deviate. Moreover, the rocker adjustment of the machine itself is almost useless. It is very troublesome to manually break the bottom plate for hardware alignment, which is very cap hat manufacturer troublesome Why do I know? Because I demolished click here

 original title: manufacturers in these shop here industries should reflect after the epidemic a new coronavirus pneumonia without gunsmoke has spread in China. As of today, the epidemic growth has slowed down. The epidemic has brought some impacts on people's lives and enterprise production, but it has also made China's science and technology level show in front of the world. Cloud computing, artificial intelligence, big data and other new technologies have appeared one after another. At the same time, many intelligent equipment have participated in the war, such as intelligent robots and logistics UAVs. Therefore, people have to re-examine and recognize these high-tech products. 2. Patrol UAV. The patrol UAV not only undertakes the tasks of publicizing the epidemic prevention measures, but also monitors the access, gathering and road traffic conditions of personnel, which greatly improves the work efficiency. 3. The UAV is equipped with disinfectant to spray ...

Guiyang Jinyang New Area high grade fingerprint lock installation | nondestructive unlocking | sales fingerprint lock mainly engaged in unlocking, repairing, changing locks, installing locks, lock engineering, building intercom engineering, opening and repairing various safes, filing cabinets, special-shaped locks, magnetic locks, electronic password box locks, anti-theft doors, various high, medium and low-grade car locks. Sell all kinds of locks. The following news about lock safety is for reference only. Ms. Wang, who lives in a nearby community, went to buy vegetables in the morning. She forgot to bring the key because of carelessness when she went out. When she came back from buying vegetables, she found that she could not enter the house. She contacted Zhang, the master of unlocking, to open the door for her. Both parties agreed that the cost of unlocking was 150 yuan. According to the work requirements, Mr. Zhang asked Ms. Wang to provide her ID card to verify her identity befo...

Jinhua domestic frequency converter I. internal main circuit structure low voltage frequency converter with "AC-DC-AC" structure, its internal main circuit is composed of rectifier and inverter, as shown in Figure 1. The three-phase alternating current input from R, s and t terminals is rectified to direct current by three-phase rectifier bridge (composed of diodes d1-d6), and the voltage is UD. Capacitors C1 and C2 are filter capacitors. Six IGBT transistors (insulated gate bipolar transistors) V1-V6 form a three-phase inverter bridge, which inverts the direct current into three-phase alternating current with adjustable frequency and voltage. Figure 1 In Figure 1, the two ends of filter capacitor C1 and C2 are connected in parallel to each other to make the voltage on the two capacitors basically equal and prevent the capacitor from being damaged in operation (at present, due to the advancement of technology, most of the electrolytic capacitors of low-voltage (380V) inv...
