Multi-function spanner of the present invention by combining the first spanner member (A1) and the second spanner member (A2) of different sizes capable of rotating the bolt or circular pipe on both ends of the handle bar (1) of various sizes The bolts or pipes can be rotated.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, FIGS. 1 to 5.

According to the drawings, the multi-function spanner of the present invention has a first spanner member (A1) and a second spanner member (A2) of different sizes capable of rotating bolts or circular pipes at both ends of the handle bar (1) Combined to rotate the various sizes of bolts or pipes.

The first and second spanner members A1 and A2 are

The coupling portion 11 is formed at an end of the handle bar 1 at an angle, and the lower end portion of the head 2 is formed so that one side is opened so that bolts or circular pipes can be fitted into the coupling portion 11. And rotatably coupled to the rivet (4), the head (2) is bent by the elastic force of the return spring (3) via the return spring (3) between the head (2) and the coupling portion (11) Configure it to return to its original position.

At this time, the thickness is thicker than the coupling portion 11 at the end of the coupling portion 11, and the upper surface is convexly convex while blocking the head 2 to which the elastic force of the return spring 3 is no longer rotated. The formed curved support portion 14 is formed, and the uneven portion 15 is formed on the surface of the curved support portion 14 to rotate the bolts or circular pipes sandwiched between the curved support portion 14 and the head 2. Make sure

Here, the shape and configuration of the head 2 will be described in more detail as follows.

The head 2 is composed of a head body 21 formed in a 'C' shape, a pair of coupling pieces for coupling to the coupling portion 11 at the lower end of the head body 21 by rivets ( 22 and a first coupling hole 12 for fitting the rivet 4 into the coupling portion 11 and a second coupling hole 28 corresponding thereto is formed in the coupling piece 22. do.

Therefore, the head 2 is rotatably coupled to the coupling portion 11 as the rivet 4 is fitted into the first and

second coupling holes

12 and 28.

On the other hand, the head body 21 is formed with a fitting groove 23 for fitting the bolt or circular pipe that is the workpiece to the inside, the fitting groove 23 in the vertical direction to the inside of the head body 21. A long side 24 formed in a long straight shape is formed, and a head side 21 is formed on the upper side of the long side 24 by forming an upper side 25 having a 'S' shape having a shorter length than the long side 24. By holding the workpiece on the upper end of the work piece is to form a ring portion 26 to be in close contact with the curved support (14).

The reason for forming the long side 24 is to rotate the bolts and pipes of various sizes that the head 2 can accommodate, and the hook portion 26 is the handle bar 1 to rotate the bolts and pipes. When rotating in one direction, the workpiece (bolts and pipes) is in close contact with the surface of the curved support portion 14 serves to rotate the workpiece.

The reason why the curved support 14 is convexly streamlined is to rotate the bolts or pipes of various sizes so that the workpiece is selectively contacted with the curved portions of the curved support 14 to make the workpiece easier to contact. This is to allow rotation.

In addition, in addition to the concave-convex portion 15 formed on the surface of the curved support 14, a separate concave-convex portion 15a is further formed on one surface of the coupling portion 11 so as to increase the contact area with the workpiece. .

Meanwhile, the installation state of the return spring 3 will be described.

A recessed groove 13 for installing the return spring 3 is recessed in one surface of the coupling portion 11 having the first coupling hole 12 into which the rivet 4 is fitted, and the coupling portion 11 is formed. 1 The return spring 3 is inserted into the rivet 4 inserted into the coupling hole 12 so that the return spring 3 is embedded in the seating groove 13, and the first spring hole 16 is mounted on the seating groove 13. ) And a corresponding second spring hole 27 is formed on the coupling piece 22, and one side end 31 of the return spring 3 is inserted into the first spring hole 16. The second end 32 of the other side is fitted into the second spring hole 27 so that the head 2 may be folded back to its original position by the elastic force of the return spring 3.

As described above, in the present invention, each of the first spanner member A1 and the second spanner member A2 is installed at both ends of the handle bar 1, and the first and second spanner members A1 and A2 are respectively provided. By setting the size differently, it is possible to rotate various sizes of bolts (or nuts) and pipes, and to allow continuous tightening work.

Referring to the case when you want to rotate a small size bolt as shown in Figure 4 (a),

When the head 2 is flipped so that the bolt is fitted into the fitting groove 23 of the head 2, the head 2 is returned to its original position by the restoring force of the return spring 3, and the loop portion 26 of the head 2 is returned. ) Is wrapped around the bolt and the bolt is fitted between the head (2) and the curved support (14), when the user rotates the handle bar (1) clockwise, the ring portion 26 tightens the bolt further Therefore, the bolt sandwiched between the ring portion 26 and the curved support portion 14 is to be rotated.

And, even when trying to rotate the bolt of a large size as shown in Figure 4 (b), while the ring portion 26 of the head 2 is in close contact with the bolt, so that the bolt is firmly in close contact with the curved support 14, a large size The bolt can also be easily rotated.

When rotating a small size bolt, the bolt is held in close contact with the front (left end of the drawing) of the curved support 14, and when rotating a large size bolt, the bolt is behind the curved support 14 (right of the drawing). However, it is rotated by being closely attached to the part.

On the other hand, Figure 5 (a) (b) is an example when rotating the circular pipe,

As in the case of rotating the bolt, the annular portion 26 of the head 2 firmly adheres the circular pipe to the curved support portion 14, so that the uneven portion 15 formed on the surface of the curved support portion 14 is provided. It will not slip and will be able to easily rotate the circular pipe.

The spanner of the present invention can continuously rotate workpieces such as bolts and pipes.

That is, when the handle bar 1 is rotated in the direction in which the workpiece is to be rotated in the state in which the workpiece is fitted into the fitting groove 23 of the head 2, the tightening force and the curved support portion of the ring part 26 ( The force supported by 14) is applied to the workpiece to rotate the workpiece, and when the handle bar 1 is rotated in the opposite direction, the tightening force of the hook portion 26 is not applied to the workpiece so that the head 2 After being slightly flipped, it can be rotated in the opposite direction as desired. Afterwards, when the handle bar 1 is rotated in the direction to be rotated again, the tightening force of the ring part 25 and the force supported by the curved support part 14 are Since the object can be rotated by being applied to the workpiece, the operator can work continuously without removing the spanner from the workpiece.

The spanner of the present invention is able to tighten or loosen bolts and pipes of various sizes in a continuous operation, which can be used very easily at home or industrial sites.
