- the side portion of the U-shaped member protrudes outward, so that a finger can be caught or It is a driver with rotation assistance according to the first invention of the present application.
- the U-shaped member of the chuck portion has a plurality of bent portions
- the overall size of the side portion projecting outward of the U-shaped member is such that the side portion projecting outward that is larger than the thickness of the handle shaft rotates with a smaller force.
- the handle shaft can be rotated with a greater force
- the fourth invention of the present application is according to claim 2, wherein a socket hole is formed in an upper end of the driver body, and a lower end of the handle shaft is fitted in the socket hole. It is a driver with rotation assistance.
- the driver body has a rectangular parallelepiped shape, and each side of the U-shaped member abuts on its four side surfaces with rigidity. It is a driver with rotation assistance of the present invention.
- a cutout portion having a predetermined depth is formed in a portion of the rectangular parallelepiped driver main body where the bent portion of the tip of the U-shaped member contacts the chuck portion.
- a rotation assist driver of the fifth invention of the present application formed.
- the driver main body is held so as to be replaceable with respect to the chuck portion, or the tip is fixed so as to be replaceable with respect to the driver main body. This is a driver with rotation assistance of the second invention of the present application.
- an eighth invention of the present application is the driver with rotation assist of the seventh invention of the present invention, which can be used as an ordinary driver in a state where the driver main body also removes the chuck force.
- a partial force S below the handle is designed so that the driver can rotate without resistance under the hand.
- the outer circumference of the shaft is larger than before so that it can be rotated using the muscles of the entire hand as well as the rotational force of the finger muscles.
- FIG. 1 to Fig. 3] D can be rotated around the axis C while the handle A is fixed.
- a single-driver system and structure that allows the main body of the clip chuck and driver to be set around the handle shaft while the handle is fixed in the palm of the hand.
- the clip chuck for setting the driver has a cross-shaped impeller shape. Since the outer periphery of the impeller is larger than the outer periphery of the driver shaft, it can be rotated powerfully and easily, and if the impeller part is used, the clip of the driver can be hooked with the index finger middle finger etc. Chuck system and structure.
- Dl and D2 in Figs. 1 to 3 are the base parts of the clip chuck. As shown in Fig. 3, the four sides of the driver are not flat! Although it is /, it is a square 1 /, which fits perfectly, and becomes a shape. This solid part of the square reduces the rotational force applied to the driver's rotating shaft.
- D3 and D4 in Fig. 1 to Fig. 3 are the tip of the clip.
- the tip shown in Fig. 3 is a panel clip so that force is applied toward the inside to keep the driver from coming off.
- the clip chuck system and structure that the panel clip holds so that the driver cannot be pulled out.
- the driver E in Figure 1 can be easily removed as shown in Figure 2. It can be set and used as required, and the tip of E2 can be changed as necessary, for example, changing to a screwdriver with a plus-type tip, or changing the tip itself.
- a driver system and structure that can be quickly replaced and used in various ways.
- the finger that rotates the driver is both rotating and holding the driver.
- the conventional driver is used by picking it with the thumb and the middle finger of the index finger, etc., but this driver can rotate with a bow that hooks the finger on the blade. In this case, you can rotate the index finger and middle finger without using the thumb, and you can use it effectively when turning like an idle rotation.
- FIG. 1 is a front view of a driver with rotation assistance according to an embodiment of the present invention.
- FIG. 9 is a front view of a driver with rotation assistance according to another embodiment of the present invention.
- A is the handle
- B is the handle fixing bracket
- B1 is the side hole
- C is the handle shaft
- D is the clip chuck
- Dl and D2 are the base of the clip chuck
- D3 and D4 are the tip of the clip chuck
- E is the dry Bar
- E1 is a driver socket hole
- E2 is a driver tip
- F is a screw
- G is an assist plate
- H is a punch
- I is a notch
- J is a screw.
- FIG. 1 is a front view of the driver
- FIG. 2 is a side view thereof
- FIG. 3 is a bottom view thereof
- Fig. 8 is a perspective view thereof.
- A is the handle.
- the width has been reduced to make it easier to fit in the palm of the hand, and the length has been reduced to one side on one side.
- the movable range of the hand can be changed by moving the hand position to the wrist side.
- B in Fig. 1 to Fig. 3 is a handle fixing bracket.
- the handle is designed not to lose its axial force. However, since the handle itself is not fixed, the handle does not come out, and the part below the handle can be rotated. That is, the handle A is provided with a lateral hole B1, and the lateral hole B1 is further provided with a hole through which the lower force handle shaft C passes. further At the same time, the upper end of the handle shaft c is fitted into the through-hole, and at the same time, an annular fixing bracket larger than the size of the through-hole is fitted into the upper end of the handle shaft c. It is fixed.
- the handle shaft C is coupled to the handle A and is rotatable.
- E in Fig. 1 to Fig. 3 is the main body of the driver, and D is the clip chuck part where the driver is set.
- This chuck portion is formed by crossing U-shaped members having two bent portions in a cross shape at the bottom and mutually using band H to use a catch plate G. Further, the auxiliary plate G is fixed to the hand nose shaft C by screws F. As described above, this chuck has an impeller shape with spring clips assembled in a cross shape.
- the U-shaped member is a metal member having a strong elasticity and rigidity at the base portion near the bottom of the U-shaped member.
- the two U-shaped cross-cross type chuck portions are rotated by hooking the finger of the right hand on the blade, that is, the U-shaped side portion. Things are possible.
- Dl and D2 in Fig. 1 are the base parts of the clip chuck. As shown in Fig. 3, it has a square shape with different steps that fits exactly on the four sides of the driver's square. This square part is designed to withstand the rotational force applied to the rotating shaft of the driver.
- D3 and D4 in Fig. 1 are the tip of the clip chuck.
- the tip shown in Fig. 3 is a spring clip so that the force is applied inward so that the screwdriver cannot be pulled out. Hold on to.
- the E driver in Figure 1 can be easily removed as shown in Figures 4, 5, 6, and 7. It can be set and used as needed. If necessary, the tip of the E2 is different. For example, you can change it to a dryper with a plus-type tip or change the tip itself for quick replacement or various uses.
- the driver itself can be used as an ordinary driver with the chuck part removed.
- FIG. 9 is a front view of a driver with rotation assistance according to another embodiment of the present invention
