The present invention relates to a stapler structure which accommodates a ruler easily and adjusts a desired stapling position quickly.
Referring to
However, as stapling a peripheral side of a paper, the ruler 2 is unnecessary and cannot be removed. Furthermore, a distance between the abutting section 4 and the extending arm 5 is too long to reduce a size of the conventional stapler.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
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.
With reference to
An accommodation seat 30 is formed on a front end of the base 10 and a rear end of the accommodation seat 30 connects with a rotation member 40. The accommodation seat 30 has a guiding groove 31 defined on a front end thereof, and the guiding groove 31 has a through trough 32 formed in a central portion thereof, wherein the accommodation seat 30 houses a locking sheet 33 which abuts against an insertion 44 on a front end of the rotation member 40 and is locked by at least one screw bolt, such that the locking sheet 33 and the rotation member 40 are in connection with the accommodation seat 30. Furthermore, the locking sheet 33 has two raised ribs 34 arranged on a front end thereof and extending out of the through trough 32 of the guiding groove 31, and a coupling plate 35 is joined with the accommodation seat 30 and has a recess 36 defined on a top thereof.
The rotation member 40 is in a U shape and has a hollow chamber 43 defined on a central portion thereof, an elongated orifice 41 formed on a central portion of a top thereof, and multiple fixing orifices 42 parallelly arranged beside two sides of the elongated orifice 41.
A movable adjuster 50 is mounted on the top of the rotation member 40, and the movable adjuster 50 has a first protrusion 51 extending outwardly from a front end thereof and has a coupling shaft 52 configured to connect a second protrusion 53 with the first protrusion 51, such that the first protrusion 51 rotates upwardly or downwardly along the coupling shaft 52. A first positioning post 54 is inserted into the elongated orifice 41 via the second protrusion 53, a second compression spring 56 is accommodated in the hollow chamber 43, and a C retaining ring 55 retains with a bottom of the second compression spring 56. In addition, two second positioning posts 57 selectively extend into two opposite of the multiple fixing orifices 42 via a bottom of the second protrusion 53.
Referring further to
As shown in
As illustrated in
As stapling a peripheral side of a paper 60, the first protrusion 51 is rotated upwardly so as to stop the paper 60. As desiring to staple a central position of the paper 60, the movable adjuster 50 is moved backwardly and the first protrusion 51 is pressed downwardly so that the paper 60 moves to locate under a bottom of the rotation member 40, thus stapling the central position of the paper 60.
While the preferred embodiments of the invention have been set forth for the purpose of disclosure, modifications of the disclosed embodiments of the invention and other embodiments thereof may occur to those skilled in the art. Accordingly, the appended claims are intended to cover all embodiments which do not depart from the spirit and scope of the invention.
