Description

Technical Field

[0001] The utility model relates to the technical field of deep hole locking screws, in particular to a locking device used for deep hole locking screws. Background Art

[0002] On the assembly line of the air conditioner electronic control box, after the PCB board is installed in the plastic shell, it is necessary to first install the PCB board on the plastic shell and fix the PCB board with screws, and then install the PCB board and the plastic shell on the PCB board on the radiator at the same time. In order to ensure that the screws are locked and not locked crooked to affect the heat dissipation effect, using traditional electric screwdrivers to lock the screws cannot meet production needs.

[0003] Since deep hole screws require longer screw lockers to ensure complete tightening, traditional electric screwdrivers may not be able to achieve the required depth and tightening force, which may cause the screws to fail to be completely fixed in the plastic shell, resulting in loose installation. If the screws are not completely tightened, the close contact between the heat sink and the PCB board may be affected, thereby affecting the heat dissipation effect and increasing the risk of overheating of components. Therefore, the existing locking device has the problem of not being able to lock deep hole screws. Utility Model Content
