Fixture structure

A fixture structure contains: a first body, a second body, and an actuation rod. The first body includes a first clamp, a holding grip, a drive mechanism, and a press lever. The actuation rod includes two extensions. The second body includes a base, a second clamp, and an accommodation groove. A locking mechanism is disposed in the base and includes two release button, two springs, and two positioning sheets. A respective positioning sheet has a flat section, two upward tilted guide sections, and a through orifice. The respective positioning sheet is urged by the respective spring to push the flat section to engage into the accommodation groove. The respective release button has multiple posts aligned with the respective positioning sheet. When the respective release button is pressed, the multiple posts push the respective positioning sheet so that the flat section removes from the accommodation groove.

FIELD OF THE INVENTION

The present invention relates to a fixture structure which contains the second body connected with or removed from the actuation rod by ways of the locking mechanism so as to clamp the workpiece quickly and easily.

BACKGROUND OF THE INVENTION

A conventional fixture is applied to clamp a workpiece made of wood by pressing a pressing lever to drive two bodies to move close to or away from each other, thus clamping the workpiece.

However, when clamping the workpiece, the second body is moved to two ends of an actuation rod and is fixed, thus causing inconvenient operation.

SUMMARY OF THE INVENTION

The primary aspect of the present invention is to provide a fixture structure which contains the second body connected with or removed from the actuation rod by ways of the locking mechanism so as to clamp the workpiece quickly and easily.

To obtain the above mentioned aspect, a fixture structure provided by the present invention contains: a first body, a second body, and an actuation rod.

The first body includes a first clamp and a holding grip, and the actuation rod is movably accommodated and moves in the first body via the second body. The first body further includes a drive mechanism configured to pull the actuation rod, and a press lever fixed on a bottom of the first body and configured to control the drive mechanism.

The actuation rod includes two extensions horizontally extending from two ends thereof, the second body includes a base, a second clamp corresponding to the first clamp, and an accommodation groove configured to receive the actuation rod.

A locking mechanism is disposed in the base and includes two release button, two springs, and two positioning sheets. A respective release button is arranged on each of two sides of the base, a respective spring is located inside the respective release button, and a respective positioning sheet has a flat section and two upward tilted guide sections. A respective upward tilted guide section is located beside each of two sides of the flat section, the respective positioning sheet has a through orifice defined on a center thereof, and the respective positioning sheet is located at the base and is urged by the respective spring to push the flat section to engage into the accommodation groove.

The respective release button has multiple posts aligned with the respective positioning sheet. When the respective release button is pressed, the multiple posts push the respective positioning sheet so that the flat section removes from the accommodation groove.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

With reference toFIGS. 1 and 2, a fixture structure according to a preferred embodiment of the present invention comprises: a first body1, a second body2, and an actuation rod3.

The first body1includes a first clamp11and a holding grip12, and the actuation rod3is movably accommodated and moves in the first body1via the second body2. The first body1further includes a drive mechanism (because the drive mechanism is a well-known art, further remarks are omitted) configured to pull the actuation rod3, and a press lever13fixed on a bottom of the first body1and configured to control the drive mechanism.

The actuation rod3includes two extensions31horizontally extending from two ends thereof. The second body2includes a base21, a second clamp22corresponding to the first clamp11, and an accommodation groove23configured to receive the actuation rod3.

A locking mechanism4is disposed in the base21and includes two release button41, two springs42, and two positioning sheets43, wherein a respective release button41is arranged on each of two sides of the base21, a respective spring42is located inside the respective release button41, and a respective positioning sheet43has a flat section431and two upward tilted guide sections432, wherein a respective upward tilted guide section432is located beside each of two sides of the flat section431, wherein the respective positioning sheet43has a through orifice433defined on a center thereof, and the respective positioning sheet43is located at the base21and is urged by the respective spring42to push the flat section431to engage into the accommodation groove23.

The respective release button41has multiple posts411aligned with the respective positioning sheet43, wherein when the respective release button41is pressed, the multiple posts411push the respective positioning sheet43so that the flat section431removes from the accommodation groove23.

Referring toFIGS. 3-8, when desiring to connect the second body2with the actuation rod3, the actuation rod3is inserted through the accommodation groove23(as shown inFIG. 3), and a respective extension31contacts with the respective upward tilted guide section432, then the respective positioning sheet43is pushed to move outward (as shown inFIG. 4) so that the respective extension31moves into the flat section431. After the through orifice433of the respective positioning sheet43is aligned with the respective extension31, the respective positioning sheet43is forced by the respective spring42to engage with the respective extension31(as shown inFIG. 5). When desiring to remove the second body2from the actuation rod3, the respective release button41is pressed to push the respective positioning sheet43by using the multiple posts411, the flat section431of the respective positioning sheet43removes from the accommodation groove23to release the respective extension41, and the actuation rod3is pulled out of the accommodation groove23(as illustrated inFIGS. 6-8).

Thereby, the second body2is connected with or removed from the actuation rod3by ways of the locking mechanism4so as to clamp the workpiece quickly and easily.

While various embodiments in accordance with the present invention have been shown and described, it is clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
