Abstract

The utility model relates to a binding file, which comprises an upper and a lower file boards, and positioning rods which are respectively and vertically fixed at both ends of the lower file board. The upper file board is sheathed on the positioning rods through positioning holes. Locking mechanisms are respectively arranged at positioning holes where the upper file board positioned. Due to the adoption of the structural characteristics, the upper file board can freely move up and down along the positioning rods when the axis of through holes overlap with the axis of positioning rods. When a power arm of a lever is pulled upward, the axis of the through holes crosses with the axis of the positioning rods. The inner wall of each through hole clamps the positioning rods tightly at the moment. Consequently, the goals of pressing and loosening vouchers or accounting books can be realized conveniently.

Description

A kind of bookbinding folder

The utility model relates to a kind of stationery, relates to a kind of bookbinding folder specifically.

The structure of existing bookbinding folder is in the backstay upper end at lower plate two ends and is provided with a screw thread, during bookbinding, the locating hole of train wheel bridge is sleeved on the backstay, by screwing nut voucher between the upper and lower clamping plate or account book are compressed then, if will take out voucher or account book, need nut is unscrewed, the aforesaid operations process is comparatively loaded down with trivial details, brings many inconvenience to the user.

The purpose of this utility model provides a kind of bookbinding folder with regard to being at above-mentioned existing in prior technology deficiency.

The purpose of this utility model can realize by following technical measures:

The utility model comprises upper and lower clamping plate, and the backstay that is vertically fixed on described lower plate two ends respectively, described train wheel bridge is sleeved on the described backstay by locating hole, is positioned at described position of positioning hole place at the upper surface of train wheel bridge and is provided with a retaining mechanism respectively.

Described retaining mechanism is a lever and is opened in through hole on this lever resistance arm; Described through hole is sleeved on the described backstay in mode movingly; The power arm of described lever extends outside the housing; Between lever resistance arm and described housing upper wall, be provided with a stage clip.

For conveniently lifting train wheel bridge, on the backstay between the described upper and lower clamping plate, be respectively installed with a stage clip.

Advantage of the present utility model just is that being positioned at described position of positioning hole place at described train wheel bridge upper surface is provided with a retaining mechanism of being made up of lever respectively, and be opened in through hole on this lever resistance arm, when described through-bore axis and described backstay axis coincided, train wheel bridge can freely move up and down along backstay; When the power arm to the moving lever of upper plate made described through-bore axis and backstay axes intersect fork, at this moment, through-hole wall tightened backstay, thereby has realized compressing and unclamping the purpose of voucher or account book easily.

Fig. 1 is a front view of the present utility model.

Fig. 2 is the A-A partial enlarged view of Fig. 1.
