Description

Special contact pin of safe formula accounting bill

The technical field is as follows:

the utility model relates to a special contact pin of safe formula accounting bill.

Background art:

at present, in the accounting field, when arranging financial document in order, often need insert some bills in bill fork needle, be used for carrying out financial document's save or collection, bill fork needle structure used at present is in inserting the contact pin for direct with the bill, when the paper of some bills is thick, when inserting the contact pin with the bill, make the below of bill slide on the contact pin easily, when exerting oneself too big, make personnel's stabbing very easily, when the contact pin does not use, the needle point exposes at the top and does not have the safeguard measure, also can cause the staff to take place the phenomenon of being stabbed by the fork needle, simultaneously, current accounting bill contact pin when needs to look for earlier time male financial document, need take off the financial document on the whole contact pin and look up, when the financial document that inserts on the fork needle is too much, the bill turns over to look for very inconveniently.

The invention content is as follows:

the utility model aims at providing a special contact pin of safe formula accounting bill.

The above purpose is realized by the following technical scheme:

a special contact pin of safe formula accounting bill, its constitution includes: holding down plate, bottom backing plate and stand slide bar, the top of bottom backing plate be connected with two perpendicularly the stand slide bar, two the stand slide bar be parallel structure, and the centre of a circle is on same water flat line, the intermediate position of holding down plate seted up the contact pin jack, the both ends of contact pin jack seted up two slide bar jacks that the diameter is the same, the face of slide bar pass the slide bar jack, the top intermediate position of holding down plate be connected with the hollow tube, the top of hollow tube be connected with the arc and press the handle, the arc press the handle the hollow tube with the holding down plate structure as an organic whole, just the inner wall pipe diameter of hollow tube with the aperture of contact pin jack the same.

The special contact pin of safe formula accounting bill, the top of stand slide bar be connected with last spacing baffle, the stand slide bar be close to intermediate position and be provided with down spacing baffle, the holding down plate with down be provided with compression spring between the spacing baffle, compression spring cover the stand slide bar on.

The special contact pin of safe formula accounting bill, the top intermediate position of bottom backing plate be connected with the combination contact pin through helicitic texture, the diameter of combination contact pin be less than the diameter of contact pin jack.

The special contact pin of safe formula accounting bill, every section intubate of combination contact pin between through helicitic texture interconnect, just needle point portion below of combination contact pin be the screw thread post structure, the screw thread post structure of the intubate of the bottom of combination contact pin close in the screw hole on the backing plate of bottom soon.

The utility model has the advantages that:

1. the utility model discloses when inserting the contact pin with the bill, at first the bill is held to one hand, place the bill between holding down plate and the contact pin, then the staff pushes down the arc clamp plate, the arc clamp plate passes through the hollow tube and is connected with the holding down plate, it moves down the clamp plate vertically when pressing the arc and pressing the handle, when the holding down plate moves down a take the altitude, the bill receives the extrusion and inserts the bill in the contact pin, then will insert the bill in the contact pin with the hand with the bill vertical slip in the below of contact pin can, loosen the arc clamp plate, elasticity through compression spring will hold down the clamp plate bounce to the primary importance can, can not cause the injury to personnel.

The utility model has the characteristics of simple structure, convenient operation etc, during the contact pin was inserted with the bill that work people's eye can be quick, when inserting the contact pin to the bill that the paper is thicker, during the contact pin was sent into to the bill that pushes down through the holding down plate, when the contact pin did not use, owing to set up the holding down plate in the top of contact pin, avoided making the needle point directly expose in the top, can guarantee staff's safety.

The utility model discloses a contact pin adopts combination formula contact pin, closes the connection through revolving between screw thread post and the thread groove each other between the needle tubing of every section contact pin, adopts the partial shipment structure with traditional solitary fork needle structure, has avoided traditional fork needle to need all take off the drawback of looking up with the bill, makes looking for of bill more swift, has also practiced thrift the time of looking for simultaneously.
