Abstract

<P>PROBLEM TO BE SOLVED: To provide a reciprocating and turning operation structure of a spanner, overcoming the disadvantage that reversing and backward moving of an opening spanner takes much time. <P>SOLUTION: This reciprocating and turning operation structure includes a spanner body 10. The spanner body is provided with an open type fitting part 11 at least at one end. The fitting part is U-shaped, and a jaw part 12 holding an engagement part such as a nut to be turned is formed in a position of a suitable depth of the U-shaped fitting part. A Y-shaped elastic part 14 including a holding jaw 16 is provided by the jaw part. A smooth part 13 having the width of an opening part a little larger than the jaw part and connected to the jaw part is formed in the further inmost position of the fitting part. Since the smooth part has a width a little larger than the width of the jaw part, the spanner body is raised by an elastic part due to looseness of force in turning operation, and released from holding of the jaw to cause a racing phenomenon, so that the backward turning in the reverse direction can be performed. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to a kind of spanner reciprocating rotation operation structure. In particular, the present invention relates to a structure of an open-type open spanner for reverse rotation recovery with a simple structure and low cost.

The known plum-shaped spanner structure mainly uses a fitting portion installed on the spanner head, is fitted to a hexagonal screwed part such as a nut, and is turned to tighten the screwed part. .
However, when an ordinary spanner is used to tighten a screwed part, it is often necessary to reciprocate the opening spanner several times. Also, when tightening or removing the threaded part, there are often obstacles around the threaded part. Therefore, after the opening spanner has rotated the screwed part to an angle at which it comes into contact with the obstacle, the opening spanner is removed from the screwed part, and the fitting portion of the open spanner is again connected to the hexagon of the screwed part. The threaded part is rotated again in accordance with the fitting portion. Thus, it is necessary to repeat the complicated procedure of rotating, removing, fitting with it, and rotating several times several times.
Therefore, since this kind of known open spanner structure needs to perform the operation | movement which adjusts to the structure of a taking-out and a hexagonal fitting part several times, it becomes troublesome when a user reversely rotates and reverses.
Furthermore, since this type of structure requires that the opening spanner fitting portion be aligned with the hexagonal fitting portion of the threaded part, the opening spanner is not threaded due to lack of space when used in a narrow space. It cannot be engaged with the joint part.
A ratchet wrench has been devised for the above drawbacks, but the structure of the ratchet wrench has many parts, so the cost becomes very high and much time is required for assembly.

In order to solve the drawbacks of the known structure, it is an object of the present invention to provide a structure for reciprocating rotation of a spanner.
The present invention utilizes the design of a jaw portion installed at the inner edge of the open-type fitting portion and a smooth portion having a larger diameter than the jaw portion, and allows the spanner body to achieve a simple and quick reverse rotation restoring function. Accordingly, the present invention solves the disadvantage that in the known spanner structure, it is only necessary to install a jaw part having the same width as the threaded part on the inner edge of the fitting part, and therefore it takes time to reversely reverse the opening spanner. be able to.
In addition, the spanner body can perform reverse rotation and retraction with a small angle as described above, which is advantageous for use in a narrow space. The known opening spanner removes the fitting portion each time, and the angle to match the screwed part again. Since it is large, it is possible to solve the disadvantage that it is not suitable for use in a narrow space.
Further, since the elastic part is attached to the jaw part of the present invention, the spanner body automatically rises due to the recovery force of the elastic part, the threaded part enters into the smooth part, and the reverse rotation and retraction of the spanner body is prevented. It can be done more quickly and without labor.
The present invention can achieve a reverse rotation and retreat function similar to that of a ratchet spanner having a complicated structure and high cost only by installing a smooth portion in the open fitting portion, and is very economical.

In order to solve the above-mentioned problems, the present invention provides the following spanner reciprocating rotation operation structure.
It mainly includes the spanner body.
The spanner body is provided with an open fitting part at least at one end. The fitting portion has a U shape, and a jaw portion that can be screwed by gripping a screwed part is formed at an appropriate depth position of the U shape fitting portion, and the jaw portion includes a clamping jaw. Provide Y-shaped elastic parts. At a position adjacent to the fitting portion, a smooth portion which is continuous with the jaw portion and whose opening width is slightly larger than the jaw portion is formed. Due to the smooth part slightly wider than the jaw part, the spanner body that has come off from the jaw part due to the elastic force of the Y-shaped elastic parts and has reached the smooth part causes an idling phenomenon and has a reverse function in the reverse direction. Achieve.

  As described above, the present invention uses the structure of the jaw portion installed at the inner edge of the open-type fitting portion and the smooth portion having a larger width than the jaw portion, and allows the spanner body to achieve a simple and quick reverse rotation restoring function. Furthermore, since the spanner body of the present invention can perform reverse rotation and retraction at a small angle, it is advantageous for use in a narrow space. Further, since the elastic part is attached to the jaw part of the present invention, the spanner body is automatically raised by the elastic force of the elastic part, the screwed part enters into the smooth part, and the spanner body reversely moves backward. Can be done more quickly and without effort. That is, the present invention can achieve a reverse rotation and retreat function similar to a ratchet spanner having a complicated structure and high cost only by installing a smooth portion in the open fitting portion, and is very economical.

As shown in FIGS. 1-4, the present invention includes a spanner body 10.
The spanner body 10 is provided with an open fitting part 11 at least at one end. The fitting portion 11 has a U-shape, and constitutes a jaw portion 12 that can be screwed by gripping a screwed part to an appropriate fitting depth of the U-shaped fitting portion 11. A resilient part 14 is installed at the gripping position of the jaw part 12, and at a position deeper than the gripping position of the fitting part 11, the jaw part 12 is continuous with the jaw part 12, and the width of the opening part is the jaw part. A smooth portion 13 slightly larger than 12 is formed. Due to the smooth part 13 having a slightly larger width than the jaw part 12, the spanner body 10 causes an idling phenomenon and achieves a reverse rotation function in the reverse direction.
The elastic component 14 installed in the jaw portion 12 is used corresponding to various types of screwed components 20, and a Y-shaped elastic component 14 having a clamping jaw 16 is used. Moreover, the sandwiching jaw 16 is designed to be bent upward at an angle of 20 to 30 degrees, and the curved sandwiching jaw 16 makes it easier to fit the spanner body 10 and the screwed part 20 together. .

When the screwed part 20 is tightened, the fitting part 11 of the spanner body 10 is used to fit onto the screwed part 20. At this time, the bolt 22 to be screwed on the screwing component 20 passes between the clamping jaws 16 (see FIG. 5). When the user subsequently applies a downward force, the elastic component 14 contracts upward by the screwed component 20 (the height of the pressed elastic component is approximately the same as the apex of the fitting portion). At the same time, the hexagonal fitting portion 21 of the threaded component 20 enters the jaw portion 12 and has a fitting relationship with the jaw portion 12 (see FIG. 6).
Further, as FIG. 7 shows, when the spanner body 10 rotates and collides with an obstacle and cannot be rotated any more, the user simply releases the force, and the elastic component 14 generates recovery elasticity, The spanner body 10 rises upward. Thus, the threaded part 20 hexagonal fitting part 21 fitted to the jaw part 12 settles in the smooth part 13 having a width larger than that of the threaded part 20 hexagonal fitting part 21 (see FIG. 8). Thus, the spanner main body 10 causes an idling phenomenon, and the spanner main body 10 quickly achieves the reverse function in the reverse direction. By repeating the above steps, the screwing function of the screwing component can be achieved.

Next, as shown in FIGS. 9 and 10, in the second embodiment of the present invention, in the first embodiment, the smooth portion 13 having a U-shape is a smooth portion 131 having a partially circular diameter. Due to the design of the smooth part 131 having a larger diameter, the idling relationship between the screwed part 20 and the spanner body 10 that have entered the smooth part 13 becomes smoother.
Further, as shown in FIGS. 11 to 13, in the third embodiment of the present invention, the main body of the spanner can be obtained by simply installing a bar-like elastic part 141 that is bent in the same manner and releasing the force in the same manner. 10 can achieve the function of increasing by elasticity.
Subsequently, as shown in FIGS. 14 and 15, in the fourth embodiment of the present invention, the elastic component 14 having the accommodation opening 17 is installed on the jaw portion 12 of the fitting portion 11. The elastic part 14 provided with the receiving opening 17 can similarly achieve the function of raising the spanner body 10 by elasticity.
In addition, as shown in FIGS. 16 and 17, in the fifth embodiment of the present invention, a semi-arc elastic component 142 constituted by an inclined elastic piece 143 is installed on the jaw portion 12 of the fitting portion 11. Similarly, the function of raising the spanner body 10 by elasticity can be achieved by the semi-arc elastic component 142.
