The screw disassembling device 10 capable of initial loosening of the screw according to an embodiment of the present invention uses the tool (driver tip) only in the screw axial direction to generate the initial loosening that requires the greatest force when disassembling the screw. It is a device that can rotate the screw head by attaching it closely.

When a tool (driver, etc.) is rotated, manpower is not used to adhere the tool (driver, etc.) to the axial direction of the screw, and the manpower is applied only to rotate, and a force that can be accurately adhered only in the axial direction of the screw is generated.

The screw joint 100 is joined to the screw 21 to be removed of the external object 20 .

The screw joint 100 includes a driver tip 110 and a tip fastening part 120 .

Since the connecting block is supported by the special screw head and the spring supporting the connecting block, it can be rotated based on the special screw.

The lever operation unit 400 is positioned to extend on one side of the rotation driving unit with the fixing unit as the center, and induces vertical movement of the screw junction to apply a force in the vertical direction when the screw junction is joined to the screw.

The lever operation unit 400 includes a clamp lever 420 that generates a force for pressing the driver tip.

The support part 410 passes one end of the connection block to the inside, and is installed in contact with the bottom surface part.

The clamp lever 420 is located on the upper end of the support part, presses the support part, and is fixed to the bottom surface part.

When the screw is assembled with a strong torque or a screw fixing agent is applied, a strong force is required to disassemble the screwdriver tip while pushing it in the screw axis direction. It is very likely that the tip will come off the screw head and wear out the grooves in the screw head.

The screw disassembling device 10 capable of initial loosening according to an embodiment of the present invention uses the fixing unit 300 and the lever operation unit 400 to disassemble the screw in a state in which the screw joint is completely in close contact in the screw axial direction. Therefore, it is possible to prevent the screwdriver tip from deviated from the screw head and abrading the groove of the screw head.

Since the thrust bearing can separate the rotational force of one side and the other side, even if the shaft fixed on one side of the thrust bearing rotates, the non-rotating housing block and the spring supported on the other side of the thrust bearing do not rotate. Therefore, it is possible to prevent twisting of the spring due to rotation of the shaft.

In addition, the pressing member 213 presses the screw joint that rises integrally when the screw rotates and rises.

In a state where the screwdriver bit is positioned on the screw head, the pressing member generates a force for pressing the screwdriver bit and the fixed shaft in the direction of the screw head. In this state, if the ratchet is inserted into the upper part of the shaft and rotated, the screw head will rotate. At this time, the screw rises in the axial direction of the screw while rotating, and the spring is compressible and can compensate for the displacement, so that the screwdriver tip can rotate while continuously pressing the screw head. As it is a device to be applied in the initial loosening section where problems may occur when disassembling the screw, displacement is not required until the screw is completely removed from the object.
