As shown in the first figure and the second figure, the valve nozzle valve (hereinafter referred to as a valve tool) includes a tool bar 10, a handle 20 combined with the first end of the tool bar 10, and a combination of the tool The picking head 30 is at the second end of the rod 10.

The picking head 30 and the tool bar 10 are combined by a structure that is detachable. The structure of the detachable set includes a combined section 11 extending from the second end of the tool bar 10, and a combined hole 31 disposed inside the first end of the picking head 30. In the first embodiment, the combination section 11 has an external thread, and the combination hole 31 is a threaded hole, and the two are combined by a screw. In order to make the combination of the two more stable, the two surfaces (or one of the surfaces) can be dispensed before the combination, so that the two are fixed by the glue in addition to the thread bonding, Make sure the two are in stable engagement. The benefit of ensuring a stable engagement between the two is that the tool bit 10 can indeed drive the pick-up head 30 whether it is rotated in the forward or reverse direction.

The second end of the pick-up head 30 is internally provided with an through hole 32 having a smaller aperture than the aperture of the combined hole 31. The inside of the picking head 30 is a spring space 33 between the through hole 32 and the combined hole 31. A waist spring 40 is disposed in the spring space 33. The two ends of the second end of the picking head 30 extend outwardly from the two latching blocks 34. The two latching blocks 34 are between the latching blocks 34.

As shown in the third figure, a conventional air nozzle 50 is described. One end of the air nozzle 50 is internally coupled with a gas valve 52 by a threaded hole 51. The air valve 52 is a conventional structure and will not be described herein. The gas valve 52 has a flat block-shaped top end 53 which is provided with a ejector pin 54 having an enlarged diameter projection 55 at the open end.

The fourth to sixth figures further describe how the valve taking tool of the present case performs the disassembly of the gas valve 52.

First, the picking head 30 of the valve taking tool of the present case is inserted into the air nozzle 50, and the two snap blocks 34 of the picking head 30 are clamped to the top end 53 of the air valve 52, even if the top end 53 is located at two In the snap groove 35 between the snap blocks 34. At this time, the ejector pin 54 and the protrusion 55 of the air valve 52 pass through the through hole 32 of the dipper head 30, and enter the waist spring 40. The waist of the smallest diameter of the waist spring 40 is engaged with the ejector pin 54. At the junction with the bumps 55. Then, the handle 20 is rotated to rotate the tool bar 10 and the pick-up head 30 synchronously. The pick-up head 30 drives the air valve 52 to rotate, and is screwed out along the internal thread hole 51 of the air nozzle 50. When the air valve 52 is disengaged from the air nozzle 50, the valve taking tool can pass the air valve 52 from the air nozzle 50 through the picking head 30 based on the buckle relationship between the waist spring 40 and the thimble 54 and the bump 55. Pull out. The manner of locking the air valve 52 is the same as described above, and only the operation direction is reversed.

As shown in the seventh and eighth figures, a second embodiment of the structure of the detachable set of the picking head 30 and the tool bar 10 is shown. The combination section 11 of the tool bar 10 is a corner column structure, and the combination hole 31 of the dip head 30 is an angular hole, and the two are mutually nested. In order to make the fit of the two sets more stable, the two surfaces (or one of the surfaces) can be dispensed before the combination, so that the two are assembled and then fixed by the adhesive to ensure stable bonding. .

The configuration of the waist spring 40 and the correspondence between the ejector pin 54 and the bump 55 of the air valve 52 will be further described herein.

As in the ninth figure, the first embodiment of the waist spring 40, that is, the embodiment described in the first to eighth figures. The first and second ends of the waist spring 40 are respectively a first flare 41 and a second flare 42. The first flare 41 and the second flare 42 are connected between the first flare 41 and the second flare 42. The waist portion 43 has a small waist 431 at an intermediate position. The inner diameters B1 and B2 of the first flare 41 and the second flare 42 are equal. The inner diameter B1 of the first flare 41 is equal to or greater than the maximum outer diameter C1 of the bump 55 of the gas valve 50. The inner diameter A1 of the small waist 431 is smaller than the maximum outer diameter C1 of the projection 55 of the air valve 50.

Accordingly, referring to the fifth and sixth figures, the picking head 30 extends into the air nozzle 50, and the thimble 54 and the protrusion 55 of the air valve 52 pass through the through hole 32 of the picking head 30. Because the inner diameter B1 of the first flare 41 of the waist spring 40 is equal to or larger than the maximum outer diameter C1 of the bump 55, the thimble 54 and the bump 55 can smoothly pass through the first expansion of the waist spring 40. The mouth 42 enters the waist portion 43 of the waist spring 40.

When the protrusion 55 reaches the small waist 431 of the waist spring 40, although the inner diameter A1 of the small waist 431 is smaller than the maximum outer diameter C1 of the protrusion 55, the coil spring of the spring has limited elastic expansion. Therefore, when the bump 55 passes through the small waist 431, the inner diameter A1 of the small waist 431 is enlarged by the bump 55, so the bump 55 can pass through the small waist 431. After the bump 55 passes through the small waist 431, the small waist 431 is returned to the original inner diameter A1, and the inner diameter A1 just snaps the boundary between the ejector pin 54 and the bump 55, so the waist spring 40 and The gas valve 50 produces a good and stable joint relationship, so that the pick-up head 30 can smoothly pull out the gas valve 50.

To disengage the gas valve 50 from the pick-up head 30, the thimble 54 and the bump 55 need to be separated from the waist spring 40 by pulling the gas valve 50 away from the pick-up head 30 because the thimble 54 The junction with the bump 55 has a funnel-shaped surface (the diameter is gradually reduced from the maximum diameter of the bump 55 to form the ejector pin 54 extending in equal diameter), so that when the gas valve 50 is pulled outward, the bump 55 can pass through the funnel The surface of the small waist 431 is enlarged, so that the bump 55 can pass through the small waist 431 in the opposite direction, so that the ejector pin 54, the bump 55 and the waist spring 40 are separated.

A second embodiment of the waist spring 40 is shown in the tenth figure. The waist spring 40 has a flared portion 435, a waist portion 436 and an extension portion 437 which is curved toward the center. The inner diameter B3 of the flared portion 435 is greater than the minimum inner diameter A2 of the waist portion 436, and the inner diameter of the extended portion 437 is equal to the minimum inner diameter A2 of the waist portion 436. The inner diameter B3 of the flared portion 435 is equal to or larger than the bump 55 of the gas valve 50. Maximum outer diameter C1. The minimum inner diameter A2 of the waist portion 436 is smaller than the maximum outer diameter C1 of the projection 55 of the air valve 50.

As shown in the eleventh figure, since the inner diameter B3 of the flared portion 435 of the waist spring 40 is equal to or larger than the maximum outer diameter C1 of the bump 55, the thimble 54 and the bump 55 can smoothly pass through the flared portion 435. And entering the waist portion 436 of the waist spring 40, because the coil spring wire of the spring has limited elastic expansion property, when the protrusion 55 passes the minimum inner diameter A2 of the waist portion 436, the minimum inner diameter A2 is enlarged by the protrusion 55. The bump 55 can pass through the minimum inner diameter A2 and enter the extension portion 437. After the projection 55 passes the waist portion 436, the waist portion 436 is returned to the original minimum inner diameter A2, and this minimum inner diameter A2 just snaps over the junction of the thimble 54 and the projection 55.

To separate the thimble 54 and the bump 55 from the waist spring 40, the valve 50 is pulled away from the picking head 30 because the apex 54 and the bump 55 have a funnel-shaped surface at the junction (from the convex The maximum diameter of the block 55 is gradually reduced to form the ejector pin 54) of the equal diameter extension. Therefore, when the gas valve 50 is pulled outward, the projection 55 can extend the minimum inner diameter A2 of the waist portion 436 through the funnel-shaped surface, thereby convex The block 55 can pass through the waist 436 in the opposite direction to separate the ejector pin 54, the bump 55 from the waist spring 40.

In summary, the valve taking tool of the present invention buckles the ejector pin 53 and the protrusion 55 of the air valve 52 with the waist of the waist spring 40, so that the valve taking tool and the ejector pin 53 of the air valve are stably engaged, so the valve taking tool is adopted. The gas valve 52 can be screwed out or locked in from the gas nozzle more stably.

The waist spring 40 is disposed in the picking head 30, and the picking head 30 is coupled to the tool bar 10 through a detachable structure. Therefore, the picking head 30 and the tool bar 10 are a two-piece combination structure. The replacement of the waist spring 40 also facilitates the tool bar 10 to combine different sizes of the picking head 30 and the waist spring 40 to disassemble the air valve 52 according to different sizes.

In order to ensure that the combination of the picking head 30 and the tool bar 10 is stable, the picking head 30 and the tool bar 10 When combined, the glue sticking is combined to enable the tool bar 10 to move the picking head 30 in the forward or reverse rotation, thereby preventing the problem that the tool bar 10 is idling or disengaging from the picking head 30. The glued head 30 and the tool bar 10 can be detached by heating the sol to separate the tool bar 10 and the pick-up head 30.
