Problems solved by technology
Due to the large number of models and the pursuit of high efficiency in production, electric screwdrivers are still used to remove the locks, resulting in tighter locks during assembly, and it is difficult to manually disassemble them for the first time.
And when the locking torque is reduced, the vibration test is easy to fall off
Therefore, the customer can only be required to use a screwdriver to dismantle it for the first time, and then manually tighten and disassemble it later, which brings some inconvenience to the customer

The invention discloses a PC case and a hand screw with an adjustable force arm. The hand screw with the adjustable force arm comprises a screw body and a cap-shaped handle fixed to the periphery of the head of the screw body in a sleeving mode. And a handle capable of rotating relative to the cap-shaped handle to open and close is arranged at the periphery of the cap-shaped handle. According to the hand screw with the adjustable force arm, the requirement for automatic assembly is met, when the fastening torque of automatic fastening installation is large, it is convenient for a client to adjust and increase the force arm of the hand screw to complete disassembly of the hand screw with small driving force in a bare-handed mode, the user experience is improved, and meanwhile extra installation space is not occupied.
Description
technical field [0001] The invention relates to the technical field of chassis assembly, in particular to a thumb screw with adjustable force arm. The invention also relates to a PC case using the thumb screw of the adjustable force arm. Background technique [0002] As customers put forward more requirements for tool-free disassembly of the chassis, our PC case side cover widely uses thumb screws, which include screws and cap-shaped handles integrated with the screws. Due to the large volume of models and the pursuit of high efficiency in production, electric screwdrivers are still used to remove the locks, resulting in tighter locks during assembly, and it is difficult to manually disassemble them for the first time. And when the locking torque is reduced, the vibration test is easy to fall off. Therefore, the customer can only be required to use a screwdriver to disassemble for the first time, and then manual fastening and manual disassembly can be performed later, whic...
