The first convex portion 513 and the second convex portion 515 can reduce the contact area between the dial 51 and the fixing base 33, so as to reduce the friction between the dial 51 and the fixing base 33, so that the dial The wheel 51 can smoothly rotate on the fixed seat 33.

The third protrusion 516 can reduce the contact area between the dial 51 and the gear 42 to reduce the friction between the dial 51 and the gear 42 so that the gear 42 does not drive the dial 51 when it rotates. Spin.

The dial 51 is further provided with a first rotation stop portion 517 and a second rotation stop portion 518. When the dial 51 rotates to the first angle, the first rotation stop portion 517 abuts the stop body 34 To prevent the dial 51 from continuing to rotate, when the dial 51 rotates to the second angle, the second stop portion 518 abuts the stop body 34 to block the dial 51 from continuing to rotate.

In the preferred embodiment, the fixing seat 33 is connected to the stopping body 34, and the stopping body 34 is fixed to the base 31 so that the fixing seat 33 is supported on the base 31 to fix the roller The gear and the rotation axis of the dial wheel, in actual implementation, the fixing seat 33 and the stop body 34 may also be separate structures, and should not be limited thereto.

The dial 51 is further provided with a first fixed-angle portion 521 and a second fixed-angle portion 522. When the dial 51 is located at the first angle, the second spring 35 abuts against the first fixed-angle portion 521 , So that the dial 51 is maintained at the first angle. When the dial 51 is located at the second angle, the second spring 35 abuts the second fixed angle portion 522, so that the dial 51 is maintained at the The second angle.

The second spring 35 has two bent portions 351 arranged at intervals and connected to the base 31, and a convex portion 352 connected to the two bent portions 351 and protruding upward. The two bent portions 351 can provide the convex The upward elastic force of the abutting portion 352 enables the user to rotate the dial 51, and the protruding portion 352 of the second spring 35 can leave the first fixed-angle portion 521 or the second fixed-angle portion 522. In an embodiment, the first fixed-angle portion 521 and the second fixed-angle portion 522 are grooves provided on the dial wheel 51. In actual implementation, this should not be limited.

The dial 51 is further provided with a dial portion 523, the dial portion 523 is exposed from the opening 38, the dial portion 523 can provide the user to apply force to control the dial 51 from the first angle Rotate to the second angle, or control the dial 51 to rotate from the second angle to the first angle.

From the above description, it can be seen that the new type of roller device does have the following effects:

1. It can provide the rotating feel of the ratchet wheel:

The first spring 32 supports the surface of the gear 42. When the roller 41 rotates, the first spring 32 exerts an elastic force on the surface of the gear 42. As the gear 42 rotates, the roller 41 can provide the rotation of the ratchet. Feel.

2. You can switch the rotation feel:

The dial 51 is switched to the first angle or the second angle. When the dial 51 moves to the first angle, the first spring 32 supports the gear 42 so that the roller 41 provides a ratcheting feel When the dial 51 moves to the second angle, the pushing portion 511 of the dial 51 contacts the first spring 32 and pushes the first spring 32 away from the gear 42 so that the roller 41 provides Smooth turning feel.

3. The angle can be fixed:

When the dial 51 moves to the first angle, the second spring 35 and the first fixed angle portion 521 interfere with each other to maintain the dial 51 at the first angle. When the dial 51 moves to the At the second angle, the second spring 35 and the second fixed angle portion 522 interfere with each other to maintain the dial 51 at the second angle, so the second spring 35 can fix the dial without external force. The angle of the wheel 51.

In summary, when the pushing portion 511 of the dial 51 leaves the first spring 32, the first spring 32 can be pressed against the gear 42 so that the roller 41 provides a ratcheting feel. The pushing portion 511 can push the first spring 32 away from the gear 42 to switch the rotating feel of the roller 41 from a ratchet to smooth. The first protrusion 513 and the second protrusion 515 can reduce the dial 51 The third protrusion 516 can reduce the friction between the dial 51 and the gear 42, and the first anti-rotation portion 517 can make the dial 51 pass the second When the position is moved to the first position, the rotation is stopped. The second rotation stop portion 518 can stop the rotation of the dial 51 when it moves from the first position to the second position. The second spring 35 can be fixed to the first position. The corner portion 521 or the second fixed-angle portion 522 interfere with each other to maintain the dial 51 at the first angle or the second angle, so that it can indeed achieve the purpose of novelty.

However, the above is only a preferred embodiment of the present model, and should not be used to limit the scope of implementation of the present model, that is, simple equivalent changes and modifications made in accordance with the scope of the patent application for the present model and the description of the model , Are still within the scope of this new patent.
