TITLE: CHUCK STRUCTURE

(a) Technical Field of the Invention

The present invention relates to a chuck, and more particularly to a chuck

structure for holding objects.

(b) Description of the Prior Art

Taiwan Patent Publishing No. 201414592, titled "Chuck Strengthening

Structure", includes a support and pressing mechanism, where the support

includes a first support arm, second support arm and assembly member, where

the assembly member is passed through the ends of the first and second

support arms, and both the fist and second support arms are provided with an

inner support rod and outer covering layer, where the inner support rod is

made of metal, and the outer covering layer strengthening plastics; the

pressing mechanism includes a threaded rod section engaged with the second

support arm. Thus, the pressing mechanism can clamp an object or objects

when turned.

During operation, it is necessary to hold a force-applying handle of the

pressing mechanism, and the handle is further turned to cause the pressing

mechanism to move relatively toward the first support arm, making the

pressing mechanism approach the first support arm, and the object can be

clamped through the clamping end and pressing end. However, when the clamping is released, the pressing mechanism needs to be screwed in the opposite direction to move relative to the first support arm, so that the pressing mechanism moves away from the first support arm, which has the disadvantages such as operational inconvenience, and time and labor consumption.

SUMMARY OF THE INVENTION

To overcome the above disadvantages, the present invention proposes a

chuck structure, including: a first chuck, provided with a seat slidable

relatively thereto, the seat provided with a first stop; a limiting element,

swingable relatively to the seat, and provided with a second chuck; and an

operating element, respectively connected with the limiting element and a

second chuck, and driving the second chuck to move relatively to the first

chuck to form an accommodation space between the first chuck and second

chuck, an elastic element configured between the operating element and

limiting element, and the elastic element pressing against the limiting element

to approach the seat, allowing the second stop and first stop to be in contact

with each other,

where the first stop and second stop respectively are a one-way sawtooth

shaped body,

where the first chuck is provided with a rail, and the seat is slidably

configured in the rail,

where the operating element and second chuck are slidably connected to

each other,

where the first chuck is provided with a protrusion.

The present invention can use the operating element 3 to adjust the size of

the accommodation space, and further can use the second stop in contact with

the first stop to make the operating element can only be rotated in a single

direction. In addition, the direction restriction on the operating element can

also be released by pushing the limiting element.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIG 1, a chuck structure of the present invention includes a

first chuck 1, limiting element 2 and operating element 3.

Referring to FIGS. 2 and 3, the first chuck 1 is provided with a seat 11

slidable relatively to the first chuck 1, where the seat 11 is provided with a first

stop 12. Specifically, the first chuck 1 is provided with a rail 13, and the seat

11 is slidably configured in the rail 13, allowing the seat 11 to be slid relatively

to the first chuck 1. The first stop 12 is one-way sawtooth shaped body

similar to a ratchet.

The limiting element 2 can be swung relatively to the seat 11 and is

provided with a second stop 21. Specifically, the second stop 21 is also a

one-way sawtooth typed body similar to a ratchet. The second stop 21 and

first stop 12 correspond to each other.

The operating element 3 is respectively connected with the limiting

element 2 and a second chuck 4 and drives the second chuck 4 to move

relatively to the first chuck 1 to form an accommodation space 5 between the

first chuck 1 and second chuck 4. Furthermore, an elastic element 6 is

configured between the operating element 4 and limiting element 2, and the

elastic element 6 presses against the limiting element 2 to approach the seat 11,

allowing the second stop 21 to be in contact with the first stop 12.

Specifically, the connection of the operating element 3 with the limiting

element 2 is formed by a bearing 31 of the operating element 3 and an axial

hole 22 of the limiting element 2 in a rotating connection shape. The

connection between the operating element 3 and second chuck 4 is formed by

a rectangular hole 32 of the operating element 3, locking element 33 and a

fixing hole 41 of the second chuck 4 in sliding connection shape, namely, the

operating element 3 is in sliding connection with the second chuck 4.

Furthermore, a protrusion 42 of the second chuck 4 is passed through a

through hole 14 of the seat 11, allowing the operating element 3 to drive the

second chuck 4 to move perpendicularly relatively to the first chuck1, where

the elastic element 6 may be a spring.

Referring to FIG 3, in an initial state, since both the second stop 21 of the

limiting element 2 and the first stop 12 of the seat 11 respectively are a

one-way sawtooth shaped body, and the operating element 3 and the limiting

element 2 are connected to each other, the operating element 3 can only be

allowed to be rotated in a single direction (that is, the direction of arrow Ain

FIG 4) by contacting the second stop 21 with first stop 12. Referring to FIG

4, the operating element 3 is pushed in the direction of arrow A upon operation

to make the operating element 3 drive the second chuck 4 in connection

therewith to move relatively to the first chuck 1, and the size of the accommodation space 5 can then be adjusted through the operating element 3.

Referring to FIG 5, the limiting element 2 can be pushed away from the seat

11 in the direction of arrow B upon release to make the second stop 21 and

first stop 12 separate from each other, and the operating element 3 can then

drive the second chuck 4 in connection therewith to move relatively to the first

chuck 1 again, and after stopping pushing the limiting element 2, the elastic

element 6 between the operating element 3 and limiting element 2 will press

against the limiting element 2 again to approach the seat 11, allowing the

second stop 21 and first stop 12 to be in contact with each other to make

operating element 3 can only be rotated in a single direction.

Referring to FIG 6, the chuck structure of the present invention can be

used to clamp an object or objects.

Referring to FIG 7, the first chuck 1 may be provided with a protrusion 8

adapted to be in combination with an electronic device to fix the electronic

device.

The present invention can use the operating element 3 to adjust the size of

the accommodation space 5, and further can use the second stop 21 in contact

with the first stop 12 to make the operating element 3 can only be rotated in a

single direction. In addition, the direction restriction on the operating

element 3 can also be released by pushing the limiting element 2.
