Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a combination of a screw and a driver that can easily abut the screw to the screw-in portion, and the screw and the driver.

[0002]

[Problems to be solved by conventional techniques and devices]

 Conventionally, when screwing is started by abutting the screw on the screwing part, the screw is held by the fingertip of one hand and the screwdriver is held by the other hand while screwing in, but it is too narrow to hold the hand. When screwing into a place, especially when screwing upward or laterally, screwing is difficult, and the screwing start work is often not smooth.

For this reason, a method has been proposed in which the screw or the driver rod has a magnetic force to attach the screw to the tip of the driver rod. However, since the screw is not firmly attached, there is a risk that it will come off when a pressing force is applied.

The present invention addresses the technical problem of solving this problem.

[0005]

[Means for Solving the Problems]

 The gist of the present invention will be described with reference to the accompanying drawings.

A screw a having a locking hole 1 vertically provided at the center of the top and a locking body 2 fitted and locked in the locking hole 1 of the screw a at the center of the tip of the driver rod 3 It relates to a combination of a screw and a driver characterized by being combined with b.

Further, a locking hole 1 into which a locking body 2 projecting at the tip of the driver rod 3 of the driver b is fitted and locked is vertically provided in the axial center direction of the center of the top. It is related to screws.

Further, the present invention relates to a driver characterized in that a locking body 2 fitted and locked in a locking hole 1 provided vertically at the center of the top of the screw a is provided at the center of the tip of the driver rod 3. It is a thing.

[0009]

[Action]

 If screwing start work is performed with the locking body 2 of the screwdriver b fitted in the locking hole 1 of the screw a, the screw a is firmly held in a continuous state with the tip of the screwdriver b in the extension direction. It is not necessary to press a with a fingertip, and the screwing start work can be easily performed.

[0010]

【Example】

 The drawings show a preferred embodiment, in which a screw a having a locking hole 1 vertically provided at the center of the top and a locking body 2 which is fitted and locked in the locking hole 1 of the screw a are provided in a driver rod 3. The present invention relates to a combination with a driver b protruding from the center of the tip of the.

In this case, the structure of the locking hole 1 and the locking body 2 is such that the relationship between the hole and the rod, the relationship between the taper hole and the punching rod, the relationship between the screw hole and the screw rod, etc. The type that does is desirable. It is also desirable to attach a holding means such as an elastic ring to the locking hole 1 side to improve the fastening effect.

[0012]

[Effect of device]

 Since the present invention is configured as described above, when the screw is started to be screwed, the screw is fixed to the tip of the driver rod in an extended state, so that the screw can be simply screwed in without being held by a fingertip. , It shows the practicality that the screwing start work can be performed very easily.
