Abstract

The invention relates to a nail clasp, and belongs to the field of civil machines. The problem that round objects cannot be hung on a nail in the wall is solved. One end of a middle joint (2) is movably connected with the position, above the middle, of a base joint (1), one end of a tail joint (3) is movably connected with the position, above the middle, of the middle joint (2), and one end of a tip joint (4) is movably connected with the position, above the middle, of the tail joint (3). The two ends of a pull line (6) are movably connected with the top of the base joint (1) and the position, below the middle, of the tail joint (3) respectively, and the two ends of a pull line (7) are movably connected with the top of the middle joint (2) and the position, below the middle, of the tip joint (4). A rack (12) is installed on a T-shaped rod (9) and can only move vertically. A sleeve fork (13) is arranged on the rack (12), and a tooth on the rack is sleeved with the sleeve fork (13). The nail clasp is used for conveniently hanging or tightly clasping objects in daily life.

Description

Nail is grabbed

Technical field

A kind of nail is grabbed, national's mechanical field.

Background technique

Nail on known wall, though can hang thing, the round object of generally losing control of one's feelings.As the round log and so on of losing control of one's feelings.

Summary of the invention

Here provide a kind of nail to grab, not only can on-hook object, can also firmly grasp object, or grab and hang circular object.

This invention is such: the place on the upper side, middle part of base pitch (1), and one end of joint (2) in flexible connection, the place on the upper side, middle part of middle joint (2), one end of flexible connection periproct (3), the place on the upper side, middle part of periproct (3), is flexibly connected slightly one end of joint (4).Base pitch (1) top, with the place on the lower side, middle part of periproct (3), be respectively flexibly connected one end of bracing wire (6), the top of middle joint (2), with the place on the lower side, middle part of joint (4) slightly, is respectively flexibly connected one end of bracing wire (7).More than group forms a mechanical finger.Tee T bar has two statures on (9), is symmetric figure, and every stature is fixedly connected with the base pitch (1) of a mechanical finger, upper at tee T bar (9), and a tooth bar (12) is installed, and tooth bar can only be moved up and down.On tooth bar (12), have cover fork (13), cover fork is overlapping a tooth on tooth bar.There is wheel disc (10) one end of cover fork (13), and rotating wheel disk just can make cover fork rotate.The place on the lower side, middle part of middle joint (2), is fixedly connected with an arc strip (8), and one end of arc strip (8) has bracing wire (5) to be movably attached on tooth bar (12).In the present invention, slightly joint can shorten, or slightly joint need not.

When use, the nail that nail is grabbed is squeezed in wall, or the tip of the nail that nail is grabbed, and fixes, and then fix on the wall with setscrew.Working principle: middle joint (2) and bracing wire coexist, and base pitch (1) is upper to be flexibly connected, but because the difference of position, the place on the upper side, middle part (with the tie point place of middle joint) of base pitch is to the distance at the top of base pitch, add the length of bracing wire (6), ability and sagacity equals middle joint (therefrom joint count with the place being connected of base pitch) to top, adds that the bottom joint of middle joint (with) of periproct arrives the mid point place on the lower side of the periproct joint of bracing wire 6 (with).So, work as rotating wheel disk, cover fork rotates, the rib tooth on cover fork cover carry-over bar, will make tooth bar move up and down time, bracing wire (5) also can move up and down, thereby pulls middle joint to move up and down.When central joint moves down, whole middle joint and periproct are along with middle joint moves down, but the top of base pitch not with middle joint and bracing wire (6) synchronizing moving, thereby make base pitch place on the upper side to this segment distance of base pitch top, and produce foldedly with its bracing wire (6), become more and turn back, so, the length of bracing wire (6), to the distance of base pitch, do not add the place on the upper side, middle part (with the tie point place of middle joint) of base pitch to the distance at the top of base pitch, thereby distance shortens.Therefore, in the process moving down at middle joint, bracing wire (6) can pull periproct, in the time that distance shortens, is bent downwardly movement along with moving down of middle joint.When periproct moves down, slightly joint also in like manner.Like this, whole mechanical finger is clenched fist with regard to turning-in.Two mechanical fingers are held to center, just can grip circular wooden stick or circular object.Very easy to use!

Owing to adopting above-mentioned design, make nail grab to hang and grab circular object and do not come off.

Brief description of the drawings

Fig. 1 is that nail is grabbed full figure.

In Fig. 1, the place on the upper side, middle part of base pitch (1), one end of joint (2) in flexible connection, the place on the upper side, middle part of middle joint (2), one end of flexible connection periproct (3), the place on the upper side, middle part of periproct (3), is flexibly connected slightly one end of joint (4).Base pitch (1) top, with the place on the lower side, middle part of periproct (3), be respectively flexibly connected one end of bracing wire (6), the top of middle joint (2), with the place on the lower side, middle part of joint (4) slightly, is respectively flexibly connected one end of bracing wire (7).More than group forms a mechanical finger.Tee T bar has two statures on (9), is symmetric figure, and every stature is fixedly connected with the base pitch (1) of a mechanical finger, upper at tee T bar (9), and a tooth bar (12) is installed, and tooth bar can only be moved up and down.On tooth bar (12), have cover fork (13), cover fork is overlapping a tooth on tooth bar.There is wheel disc (10) one end of cover fork (13), and rotating wheel disk just can make cover fork rotate.The place on the lower side, middle part of middle joint (2), is fixedly connected with an arc strip (8), and one end of arc strip (8) has bracing wire (5) to be movably attached on tooth bar (12).
