DETAILED DESCRIPTION OF THE INVENTION

The following is a better example to execute this invention, which thus does not restrict the protective scope of this invention.

Please refer to attached FIG. 1 to attached FIG. 5: this invention of binding machine is mainly composed of Main Body 10, Non-Slip Mat 20, Scroll 30, Ratchet Wheel 40, Hand Knob 50, Spring leaf 60, Control Pulling Plate 70.

Among them, Main body 10 is made of steel plate, and has a level bottom board, which's left and right sides kink to form Side Plate 11. The two Side Plates 11 form the hollow cavity. To make main body 10 look better and enhance comfortable operation,

Non-slip mat 20, which is made of soft plastic materials and is connected with the bottom board of Main Body 10, has hand piece 21 that is attached to two Side Plates 11 of main body 10. There is recess 211 that goes match with fingers in hand piece 21. In addition, on the rear side of Non-slip mat 20, there is a retaining wall 22 that links with hand piece 21. Retaining wall 22 is attached to the steel plate on the rear side of main body 10, and there is retaining wall 221 in the middle that allows for the passage of lacings.

Scroll 30 is inside the hollow cavity formed by the two side plates 11 of main body 10, and there is the horizontal locating notch 301 allows for the passage of lacings in the middle. The left and right ends of scroll 30 go through side Plate 11. There is plastic knob 31 on its end in order for the users to rapidly retract and release the lacings by directly rotating Scroll 30.

Two ratchet wheels 40 are set in the outside of the hollow cavity formed by two Side Plates 11 of main body 10 (surely it can also be set inside the hollow cavity). Two ratchet wheels 40 are set on the two sides of scroll 30, which can drive scroll 30 to rotate.

Hand knob 50 crosses above main body 10, and the side plates 51 on its left and right sides are respectively connected with the left and right ends of scroll 30, and it can rotate back and forth around the central axis. Spring leaf 60, is located between two side plates 11 and in the rear side of scroll 30, with its front end goes together with Ratchet 40 to prevent the reverse rotation of ratchet 40.

Control pulling plate 70 is located between two side plates 51 of hand knob 50. Its projecting parts on the left and right ends are inserted into Fastener 52 on Side Plate 51 that is fixated on hand knob 50, and they can move up and down along the sliding way of fastener 52. Their bottom can maintain the contact with ratchet wheel through the elastic force of compressing spring 53 inside Fastener 52. When the user pushes hand knob 50, Control Pulling Plate 70 can drive scroll 30 to rotate.

Main lacing 80 is within the hollow cavity formed by two Side Plates 12 of main body 10, and it goes through the horizontal retaining nest 31 in the middle of scroll 30. Its two ends project out of the front and back sides of Main Body 10. Among them, there is the main hook 81 in the tail of lacing that reaches to the rear of Main Body 10. The lacing tail that extends out to the front of main body 10 circles for several rounds and is sewed together, which forms Knot 82. The thickness of knot 82 must be larger than the horizontal retaining Nest 301 in the middle of Scroll 30, which can prevent Main Lacing 80 from taking off scroll 30.

The tail of auxiliary lacing 90 is fixated in horizontal beam 12 in the front side of main body 10, and there is the auxiliary hook 91 that goes together with main hook 81 in its front end.

Before using this utility model, hold the handle on the top end Hand knob 50 first, and use the fingers to pull up Control Pulling Plate, push hand knob 50 forward. The bottom of control pulling plate 70 relieves ratchet wheel 40 of its restriction. Then, you can pull main lacing 80 to a proper length to tie up the objects.

When the object is tied up, hold the handle of hand knob 50 with your hands, and press Hand Knob 50. Control pulling plate 70 brings scroll 30 to rotate some angle clockwise through ratchet wheel 40. Afterwards, use the fingers to pull up control pulling plate 70 and push hand knob 50 forward in position and then press down hand knob 50. Repeat for several times. Then retract main lacing 80 tightly to have the object tied up firmly by main lacing 80 and auxiliary lacing 90.
