FIELD OF THE INVENTION

The present invention relates to a stapler structure which accommodates a ruler easily and adjusts a desired stapling position quickly.

BACKGROUND OF THE INVENTION

Referring toFIG. 1, a conventional stapler contains: a base1, a ruler2, and a stapling mechanism3. The base1includes an abutting section4arranged on a bottom thereof and an extending arm5extending upwardly from a top of the abutting section4. The abutting section4is fixed on a desk, and the ruler2is in connection with a free end of the abutting section4. The stapling mechanism3is coupled with a free end of the extending arm5and includes an outlet6defined one end thereof corresponding to a notch7of the ruler2.

However, as stapling a peripheral side of a paper, the ruler2is unnecessary and cannot be removed. Furthermore, a distance between the abutting section4and the extending arm5is too long to reduce a size of the conventional stapler.

SUMMARY OF THE INVENTION

The primary objective of the present invention is to provide a stapler structure which accommodates a ruler easily and adjusts a desired stapling position quickly.

To obtain above-mentioned objective, a stapler structure provided by the present invention contains: a base, a stapling mechanism, and a press block.

A rear end of each of the stapling mechanism and the press block is in connection with a connector on a rear end of the base, and the stapling mechanism includes an elastic sheet disposed on a bottom thereof.

The stapling mechanism also includes a trigger portion arranged on a front end thereof and accommodating a control column, and the control column fits with a first compression spring and has a horizontal stein laterally extending from a top of the control column, wherein the horizontal stein has a slot defined on a bottom thereof, and the first compression spring abuts against the slot and a top of the trigger portion, two ends of the horizontal stein retain with two holders on two front sides of an interior of the press block, respectively, and two bearings fit with the two ends of the horizontal stein.

An accommodation seat is formed on a front end of the base and a rear end of the accommodation seat connects with a rotation member, the accommodation seat has a guiding groove defined on a front end thereof, and the guiding groove has a through trough formed in a central portion thereof, wherein the accommodation seat houses a locking sheet which abuts against an insertion on a front end of the rotation member and is locked by at least one screw bolt, such that the locking sheet and the rotation member are in connection with the accommodation seat, wherein the locking sheet has two raised ribs arranged on a front end thereof and extending out of the through trough of the guiding groove, and a coupling plate is joined with the accommodation seat and has a recess defined on a top thereof.

The rotation member is in a U shape and has a hollow chamber defined on a central portion thereof, an elongated orifice formed on a central portion of a top thereof, and multiple fixing orifices parallelly arranged beside two sides of the elongated orifice.

A movable adjuster is mounted on the top of the rotation member, and the movable adjuster has a first protrusion extending outwardly from a front end thereof and has a coupling shaft configured to connect a second protrusion with the first protrusion, wherein a first positioning post is inserted into the elongated orifice via the second protrusion, a second compression spring is accommodated in the hollow chamber, and a C retaining ring retains with a bottom of the second compression spring, wherein two second positioning posts selectively extend into two opposite of the multiple fixing orifices via a bottom of the second protrusion.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

With reference toFIGS. 2 to 5, a stapler structure100according to a preferred embodiment of the present invention comprises: a base10, a stapling mechanism13, and a press block20. A rear end of each of the stapling mechanism13and the press block20is in connection with a connector11on a rear end of the base10, and the stapling mechanism13includes an elastic sheet12disposed on a bottom thereof. The stapling mechanism13also includes a trigger portion14arranged on a front end thereof and accommodating a control column16, wherein the control column16fits with a first compression spring15and has a horizontal stein17laterally extending from a top of the control column16, wherein the horizontal stein17has a slot18defined on a bottom thereof, and the first compression spring15abuts against the slot18and a top of the trigger portion14, two ends of the horizontal stein17retain with two holders21on two front sides of an interior of the press block20, respectively, and two bearings19fit with the two ends of the horizontal stein17.

An accommodation seat30is formed on a front end of the base10and a rear end of the accommodation seat30connects with a rotation member40. The accommodation seat30has a guiding groove31defined on a front end thereof, and the guiding groove31has a through trough32formed in a central portion thereof, wherein the accommodation seat30houses a locking sheet33which abuts against an insertion44on a front end of the rotation member40and is locked by at least one screw bolt, such that the locking sheet33and the rotation member40are in connection with the accommodation seat30. Furthermore, the locking sheet33has two raised ribs34arranged on a front end thereof and extending out of the through trough32of the guiding groove31, and a coupling plate35is joined with the accommodation seat30and has a recess36defined on a top thereof.

The rotation member40is in a U shape and has a hollow chamber43defined on a central portion thereof, an elongated orifice41formed on a central portion of a top thereof, and multiple fixing orifices42parallelly arranged beside two sides of the elongated orifice41.

A movable adjuster50is mounted on the top of the rotation member40, and the movable adjuster50has a first protrusion51extending outwardly from a front end thereof and has a coupling shaft52configured to connect a second protrusion53with the first protrusion51, such that the first protrusion51rotates upwardly or downwardly along the coupling shaft52. A first positioning post54is inserted into the elongated orifice41via the second protrusion53, a second compression spring56is accommodated in the hollow chamber43, and a C retaining ring55retains with a bottom of the second compression spring56. In addition, two second positioning posts57selectively extend into two opposite of the multiple fixing orifices42via a bottom of the second protrusion53.

Referring further toFIGS. 2 to 4, a ruler27is housed in the guiding groove31of the accommodation seat30and has an opening38configured to retain with the two raised ribs34.

As shown inFIGS. 5 to 7, the press block20is pressed so that the horizontal stein17rotates on the two holders21by way of the two bearings19, and the control column16is driven by the horizontal stein17to actuate the trigger portion14, wherein when the horizontal stein17presses downwardly, the first compression spring15is accommodated in the slot18, hence the press block20moves upwardly to an original position.

As illustrated inFIGS. 5 and 8-10, when the first protrusion51of the movable adjuster50rotates 45 degrees, it pushes the second protrusion53upwardly so that the two second positioning posts57remove from said two opposite fixing orifices42of the rotation member40, and the movable adjuster50is moved toward a desired position of the elongated orifice41, then the first protrusion51is rotated upwardly or downwardly so that the two second positioning posts57extend into said two opposite fixing orifices42, thus fixing the movable adjuster50.

As stapling a peripheral side of a paper60, the first protrusion51is rotated upwardly so as to stop the paper60. As desiring to staple a central position of the paper60, the movable adjuster50is moved backwardly and the first protrusion51is pressed downwardly so that the paper60moves to locate under a bottom of the rotation member40, thus stapling the central position of the paper60.
