In addition, due to the small size of the bills, traditional financial binding machines all perform two-hole binding, which is not compatible with the binding of documents such as archives, and has a small scope of application for binding. In the prior art, in order to be able to use different binding objects and binding methods, a drill and a threading needle are movably provided to adjust the hole distance, so that it is compatible with more binding objects and binding methods.

[0036] A multi-purpose multi-hole file financial binding machine, such as Figures 1 to 8 As shown, it includes a frame 1, a threading device, a drilling device 3 and a control circuit. The drilling device 3 is arranged on the upper part of the frame 1, the threading device is arranged on the lower part of the frame 1, and a binding platform 11 is arranged in the middle part of the frame 1. The control circuit is electrically connected to the drilling device 3. The drilling device 3 is provided with at least four drill clamping mechanisms arranged at intervals along the transverse direction. The threading device is respectively provided with a threading clamping mechanism corresponding to the position of each drill clamping mechanism. Two or three of the drill clamping mechanisms of the drilling device 3 are movably installed with a drill 4, and a threading needle 21 movably installed on the threading clamping mechanism is respectively provided under each drill 4. The binding hole spacing of traditional financial binding machines is fixed, and most of them adopt single hole or two holes, which can only perform two-hole binding on bills, and bills can only be bound flat or obliquely, and the scope of application is small. The existing financial binding machines that can adjust the binding hole spacing are realized by moving the position of the drill 4, which leads to complex structure, high cost, poor reliability and stability. The utility model can perform two-hole binding by installing two drills 4 and corresponding two threading needles 21, and can perform three-hole binding by installing three drills 4 and corresponding three threading needles 21, so that the switching of two-hole or three-hole binding can be performed, and the flexibility is high; by selectively installing the drill 4 and the corresponding threading needle 21, the binding hole spacing can be adjusted, and files and bills can be bound flat or obliquely with two holes or three holes, so that it is applicable to both bill and file binding at the same time, and the scope of application of binding is expanded; the position of the drill clamping mechanism and the threading clamping mechanism is fixed, and only the drill 4 and the corresponding threading needle 21 need to be disassembled and assembled, so the structure is simple, the cost is low, and the reliability and stability are high.

The chip receiving box 37 is magnetically attracted to the drill bit sleeve 35 by a magnet, which is convenient for disassembly and cleaning.

[0052] Specifically, the drilling device 3 is also provided with a paper pressing mechanism 5, which includes a paper pressing paperboard 51, two paper pressing guide pillars 52 and two paper pressing springs 53.

The paper pressing paperboard 51 is provided with a knife groove 511 at the position corresponding to each drilling tool 4. When the drill sleeve 35 descends, the paper pressing paper 51 is pushed downward by the paper pressing spring 53 until it is pressed against the binding object. When the drill sleeve 35 moves upward, the paper pressing paper 51 is kept pressed against the binding object under the action of the paper pressing spring 53 until the drill sleeve 35 pulls the paper pressing guide post 52 to drive the paper pressing paper 51 upward to reset.
