Meanwhile, the main body 200 serves to connect and support the respective components. 2, the rotary shaft 400 is installed to be rotatable through a central portion of the main body 200, and the handle 100 is preferably provided on at least one side of the main body 200 The spring 700 is fixed to the inner surface of the main body 200 and the latch 800 is connected to the main body 200 by being coupled to the spring 700, The spring 500 and the ratchet wheel 600 are connected to the main body 200 by being installed on the rotation axis 400 as a central axis.

Next, the rotation shaft 400 is rotatably installed through the center of the main body 200, and an end of the rotation shaft 400 is fixedly coupled to a central portion of the handle 100. This configuration is for rotating the rotary shaft 400 inside the main body 100 by rotation of the handle 100 (operation by the user). The rotation of the rotation shaft 400 rotates the winding spring 500 to accumulate elastic energy in the winding spring 500.

Meanwhile, the rotary shaft 400 is provided with the driver blade 300 at least at one end thereof. This is because elastic energy is accumulated in the spring 500 by a series of processes and then the driver blade 300 rotates together when the rotation axis 400 is rotated by the accumulated elastic energy, So that the screws can be loosened or tightened without being caught.

Here, the driver blade 300 may be formed by various methods, for example, a method in which the driver blade 300 is integrally coupled to at least one end of the rotation shaft 400, Or a method in which the driver blade 300 is inserted and fixed to the hollow portion A formed at the end of the rotation shaft 400 as shown in FIGS. 1 to 3 may be used.

In this case, the driver blade 300 may be provided on the rotation axis 400 And is inserted and extracted into the hollow portion A of the main body A. In this case, the tabs 310 and 320 having different shapes are formed on both end surfaces of the driver blade 300 so that the user can select the tab according to the shape of the screw, insert the tab into the hollow portion A, (300).

Here, the magnet 1000 is made of a neodymium magnet, and is suitable for fixing the driver blade 300 by a strong magnetic force.

Next, the manual winding spring 500 automatically rotates the rotation shaft 400 and the driver blade 300 through a series of processes, and is wound around the rotation axis 400 as a center axis. Hereinafter, the series of processes will be described in detail. When the rotation of the rotation shaft 400 by the handle 100 causes the winding spring 500 to be wound, elastic energy is accumulated in the winding spring 500, A process of rotating the driver blade 300 provided on at least one end of the rotation axis 400 and the rotation axis 400 while the spring 500 is released by elastic energy (restoring force of the spring) It says.

Specifically, when the latch 800 is engaged with the teeth of the ratchet wheel 600, the handle 100 and the rotary shaft 400 can be rotated only in one direction by the ratchet wheel 600, Elastic energy is accumulated by rotating the handle 100 and the rotation shaft 400 by winding the winding spring 500 in one direction so that the winding spring 500 is wound. However, when the latch 800 is separated from the teeth of the ratchet wheel 600, the function of controlling the rotation direction of the handle 100 and the rotation shaft 400 is lost.

2, the position where the ratchet wheel 600 is installed may be provided on the outer bottom surface of the handle 100, between the handle 100 and the main body 200, Although not shown, may be installed inside the main body 200. This can be easily modified by a person skilled in the art.

Next, the latch 800 controls the rotation direction of the handle 100 and the rotation shaft 400 together with the ratchet wheel 600, as described above. To this end, the latch 800 is coupled to a spring 700, one end of which is fixed to the inner surface of the main body 200, and the other end of the latch 800 is hooked on the teeth of the ratchet wheel 600. 2, the inner surface of the main body 200, on which the spring 700 is installed, is disposed on one side of the main body 200 on the opposite side of the position where the ratchet wheel 600 is installed, The spring 700 is compressed by the movement of the latch 800 and the latch 800 can be moved again by the restoration of the compressed spring 700. [ For reference, the process of moving the latch 800 and the operation thereof will be described in the operation process of the driver tool according to the present invention.

As shown in FIG. 2, the latch 800 preferably has a rod shape or a cylindrical shape.

Next, the moving member 900 moves the latch 800 so that the latch 800 is engaged with the teeth of the ratchet wheel 600 and the latch 800 is moved from the ratchet wheel 600 It also plays a role of separating. For this, the moving member 900 is fixed to the latch 800 to move the latch 800 in the axial direction X of the rotating shaft 300. For reference, the axial direction X of the rotary shaft 400 refers to the center of rotation of the rotary shaft 400, that is, the same direction as the rotary shaft 400. In FIG. 2, 400 in the axial direction.

2, a groove B is formed in one side surface of the main body 200 to allow the movable member 900 to move, The moving member 900 may be inserted into the groove B and fixed to the latch 800. Here, the method of fixing the moving member 900 to the latch 800 is not particularly limited, and a known method such as screw coupling may be used.

<Operation procedure>

The user moves the movable member 900 in the direction in which the ratchet wheel 600 is installed so that the latch 800 engages with the teeth of the ratchet wheel 600, The winding is rotated a certain number of times in the direction. The rotation of the handle 100 causes the rotation shaft 400 fixed to the handle 100 to rotate, and the spring of the spring 500 is wound. By this process, elastic energy is accumulated in the spring 500.

Then, the user aligns the tab formed on the end face of the driver blade 300 with the screw groove.

Thereafter, the shifting member 900 is moved in a direction in which the ratchet wheel 600 is not installed, and the latch 800 is separated from the ratchet wheel 600. The rotation direction control of the handle 100 and the rotary shaft 400 by the ratchet wheel 600 and the latch 800 is released and as a result the elastic energy accumulated in the spring 500 The rotary shaft 400 is rotated in the direction in which the spring 500 is released and the driver blade 300 is rotated by the rotation of the rotary shaft 400. [ By the rotation of the driver blade 300, the screw corresponding to the tab formed on the end surface of the driver blade 300 is tightened or loosened.

According to the above-described process, since the screw is tightened or loosened by the elastic energy (restoring force of the spring) stored in the spring 500, the user can perform the operation of tightening or loosening the screw without applying any force.
