Description

 Hand tool telescopic structure  

The invention relates to a telescopic structure of a hand tool, in particular to a telescopic structure of a hand tool which is provided with a locking collar, the second locking portion of the locking collar interacts with the first locking portion of the body when the locking When the collar is against the rear side of the control collar, the control collar is less likely to move.

As previously known to us, a conventional hand tool telescopic structure, as shown in U.S. Patent No. 6,408,721, is based on the use of the control sleeve 30 to drive the two positioning beads 32 to drive the two positioning beads 32. Embedding into a ring groove 220 of the driving rod 22 to achieve the telescopic positioning effect, or allowing the two positioning beads 32 to be disengaged from the ring groove 220 on the driving rod 22 to achieve the driving rod 22 at the handle The purpose of the telescopic movement in 10 is to adjust the relative position of the drive rod 22 to the grip 10.

But the lack of the patent structure lies in:

1. The shifting of the control sleeve 30 controls the two positioning beads 32 to be embedded in or out of the annular groove 220, and the control sleeve 30 is not displaced by the elastic force of the elastic member 34. The control sleeve 30 may automatically displace the organic rate of the control sleeve 30 by other external forces to overcome the elastic force of the elastic member 34, and the elastic force of the elastic member 34 is used to impinge, and the control sleeve 30 is caused by the organic rate causing the automatic displacement. .

2. After the two positioning beads 32 are positioned, the two positioning beads 32 are embedded in the ring groove 220 of the driving rod 22, so the handle 10 is free to rotate on the driving rod 22, and once the grip When the handle 10 is rotated relative to the driving rod 22, when the hand grips the handle 10 to rotate, the force of rotating the handle 10 is easily converted into a rotating force for rotating the handle 10, and the hand holds the grip. When the handle is 10, it is easy to cause the loss of the hand.

In view of the lack of the structure of the telescopic portion of the above-mentioned hand tool, the inventors have been engaged in the manufacturing, production, and design experience of related industries for many years, and finally have a product that can solve the drawbacks of the hand-tool expansion and contraction structure.

In the telescopic structure of the hand tool, the control sleeve may automatically shift the organic rate of the control sleeve by other external forces to overcome the elastic force of the elastic element. The present invention is provided with a locking collar, and the second locking portion of the locking collar And interacting with the first locking portion of the body, the control collar is less likely to move when the locking collar is against the rear side of the control collar.

A hand tool telescopic structure, comprising: a system having a receiving groove, a first perforation, a first ring groove and a first locking portion; a control collar is sleeved at a front end of the body, the control sleeve The ring system can be axially moved to a release position and a snap position on the body, the control collar is provided with a spring groove, a retaining edge and a tapered groove; a first buckle ring sleeve is sleeved on the first ring a first elastic member is sleeved on the body and is biased against the retaining edge and the first buckle; a positioning bead is received in the first through hole; a driving rod is disposed on the In the accommodating groove, the driving rod is provided with an axially disposed guiding groove and a plurality of positioning grooves; a locking collar is sleeved on the body, and the locking collar is fastened to the rear side of the control collar, so that The control collar is limited to be displaceable by the locking collar, and the locking collar is provided with a second locking portion, and the second locking portion acts on the first locking portion to make the locking collar The axial displacement of the first locking portion is such that the locking collar does not abut against the rear side of the control collar, the control The collar can be displaced.

The second locking portion of the locking collar interacts with the first locking portion of the body to axially displace the control collar within the range of the first locking portion when the locking collar is in contact with When the control collar is on the rear side, the control collar is limited to the locking collar, and the control collar is less likely to move freely on the body, and the positioning bead is less likely to have an organic rate from the positioning slot. Disengaged, the drive rod is in a fixed position relative to the body.

The structure and composition of the present invention are described in conjunction with the drawings and the drawings, and the following description is only for explaining the implementation of the present invention.

The driving rod 70 depicted in the first figure of the present invention is a ratchet wrench structure, and the thirteenth drawing is a rotating rod structure. Similarly, the driving rod 70 can be a protective range for various hand tool structures.

The advantages of the hand tool telescopic structure of the present invention are:

The second locking portion 91 of the locking collar 90 interacts with the first locking portion 14 of the body 10 to axially displace the control collar 90 within the range of the first locking portion 14. When the locking collar 90 abuts against the rear side of the control collar 20, the control collar 20 is limited to the locking collar 90, and the control collar 20 is less likely to automatically move on the body 10. The positioning bead 50 is unlikely to be disengaged from the positioning groove 72, and the driving rod 70 is in a fixed position relative to the body 10.

2. In the normal operating state, the locking collar 90 does not abut against the rear side of the control collar 20, so that the total length between the driving rod 70 and the body 10 is conveniently adjusted, but in a special state. Preferably, the locking collar 90 abuts against the rear side of the control collar 20 to prevent the control collar 20 from being displaced by other factors, and thus has safety. The locking collar 90 has the necessary state. Safety design.

3. The second elastic member 80 is elastically abutted between the accommodating groove 11 and the driving rod 70, so that the telescopic structure of the hand tool is tied to the shortest length, that is, the length of the fifth figure, the positioning bead 50 is off. After the positioning groove 72 is opened, the elastic force of the second elastic member 80 can automatically eject the driving rod 70 from the receiving groove 11.

4. The driving rod 70 is a ratchet wrench structure. When the working end of the driving rod 70 is placed on a plane upward, the guiding slot 71 is upwardly oriented, that is, the driving rod 70 is placed. In a plane, the first through hole 12, the guiding groove 71 and the positioning groove 72 are all upwards, that is, the positioning bead 50 is easier to install.

5. As shown in the seventh figure, when the control collar 20 is in the buckle position, the positioning bead 50 is pushed by the inner circumferential surface of the tapered groove 23, so that the positioning bead 50 can be embedded. It is located in a positioning slot 72.

6. In addition, as shown in FIG. 11 and FIG. 12, when the control collar 20 is in the release position, one end of the larger inner diameter of the tapered groove 23 is located at the positioning bead 50, that is, the The positioning bead 50 can be moved outwardly to be disengaged from the positioning slot 72. The positioning bead 50 can be freely displaced at the guiding slot 71 of the driving rod 70. The driving rod 70 can be opposite in the receiving slot 11 Move the position to achieve the purpose of telescopic adjustment length.

7. The closure member 60 closes the opening between the body 10 and the tapered groove 23. The sealing member 60 can prevent the positioning bead 50 from moisture or rust and affect the displacement of the driving rod 70. The effect.

Therefore, the structure of the telescopic part of the hand tool of the invention has industrial utilization, novelty and progress, and can meet the application requirements of the invention patent, and submits an application according to law.
