Ratchet structure

The creation department is related to a ratchet structure, especially a ratchet structure is provided with a second body, the second system can be rotated by the user, and the control unit of the control group is adjusted to adjust the switching direction, so that the ratchet structure is created. The second body is adjusted to achieve the control effect of the two-way switching.

As previously known to us, the conventional ratchet structure, such as U.S. Patent No. US7434493B2, and Taiwan Patent Application No.: 095212552, certificate number: M308143, the patent name: ratchet device, a ratchet device, suitable for various screwdriver head installations The ratchet device includes a fixed unit 3 including a longitudinally extending body 31. The body 31 has a working end surface 311, a driving end surface 312 opposite to the working end surface 311, and a connecting operation and driving end surface 311. The outer peripheral surface 313 of the 312, and the two mutually spaced receiving grooves 34 are adjacent to the working end surface 311. Each receiving groove 34 extends through the body 31 and opposite ends are formed on the outer peripheral surface 313. a switching unit 4 includes a switching ring 41 rotatably sleeved on the body 31, the switching ring 41 has four latching slots 414 corresponding to the receiving groove 34 formed on an inner peripheral surface; and a ratchet unit 5, comprising a set of a working surface 311 disposed on the body 31 and a ratchet wheel 51 for mounting the driver head, and two elastic members 52 respectively disposed on the receiving slots 34, and respectively disposed on a first latch 53 , a second latch 54 , a third latch 55 and a fourth latch 56 at opposite ends of the elastic member 52 , the latching slots 414 respectively for the latches 53 , 54, 55, 56 extend, the ratchet 51 has a plurality of rings arranged on an inner peripheral surface of the ratchet restricted by the fingers 53, 54, 55, 56 511.

But the missing structure of this custom structure is:

1. The switching ring 41 of the switching unit 4 of the conventional ratchet device has a certain thickness, so that the overall height of the conventional ratchet device is increased.

2. The ratchet unit 5 is provided with a first latch 53 , a second latch 54 , a third latch 55 and a fourth latch 56 . The components are complicated and complicated, and the conventional ratchet device is increased. The cost of making components.

3. The switching unit 4 is pivotally disposed on the body 31. The switching unit 4 may automatically rotate due to impact, drop or other possible factors, such that the switching unit 4 has an automatic switching ratchet device that is reversed.

In view of the lack of the ratchet structure of the above-mentioned conventional patent case, the creator has borrowed many years of experience in related industries, and finally has a product that can solve the drawbacks of the ratchet structure.

The conventional ratchet structure needs to be achieved with another component. Switching to the effect of positive reversal, the creation is related to a ratchet structure, especially a ratchet structure is provided with a second body, the second system can be rotated by the user, and the control unit of the control group is adjusted to adjust the switching direction. The artificial ratchet structure is used to adjust the second body to achieve the effect of controlling the two-way switching.

A ratchet structure comprising: a first book The system is provided with a first pivoting portion, a first acting end, a second pivoting portion, an actuating slot and a missing slot; a ratcheting system is pivotally disposed at the first active end, the ratcheting wheel is provided with a ratchet portion; The toothing system is provided with a plurality of occlusal portions for engaging the ratchet portion; a control group includes a control member, a top cap and a first elastic member, and the front end of the control member is provided with a third pivot Department, the third pivotal pivot In the second pivot portion, the control member is provided with a protruding rod, and the protruding rod is received in the actuating groove, and the protruding rod is displaceable in the actuating groove by the third pivot portion. The end of the extension rod is provided with a groove, and the two sides of the front end of the third pivot portion are respectively provided with abutting surface, and the two abutting surfaces are respectively provided with a first control portion; the top hat is received at the front end of the groove; The elastic element is received in the groove, the elastic element is configured to abut the top cap against the tooth; a second system is provided with a fourth pivot, the fourth pivot is pivoted on the first pivot The second body is provided with an outer peripheral surface, and the outer peripheral surface is provided with a second control portion.

The ratchet structure of the creation is controlled by the second body The switching direction of the workpiece, and then the top hat of the control group drives the teeth to engage with the ratchet, so that the ratchet structure achieves the effect of two-way control. When the second system is close to being vertical, the second control unit can be used to move the first control unit to the other end. When the second body drives the first body and the ratchet to rotate the screw, the second body Most of the rotation with the first body is in a state of rotation between two and ninety degrees, and it is impossible for the second body to switch the control member when it is rotated. After the switching is reversed, the control surface of the control group is limited to the outer circumferential surface of the second body, and the control component cannot automatically switch forward and reverse due to falling, impact or other factors, and it is impossible to automatically switch positively. The reversal is a creative design for the creation.

In order to enable the members of the Board and those skilled in the art to fully understand the effects of this creation, the structure and composition of the creation are described in conjunction with the drawings and drawings, but the following are only used to explain the implementation of this creation. For example, it is not intended to impose any form of restriction on this creation. Any modification made in the spirit of this creation should still fall within the scope of this creation.
