Description

Technical Field

[0001] The utility model belongs to the technical field of office supplies, and in particular relates to an environmentally friendly stapler. Background Art

[0002] Stapler is one of the tools widely used in daily office work. Traditional staplers are composed of a cover, a staple box and a base. The staplers are made of ferroalloy. Recycled paper often contains staplers, which are often crushed together with the paper during recycling and cannot be separated. As a result, the recycled paper is mixed with heavy metals, which reduces the texture and biosafety of the paper and reduces the use value of the recycled paper.

[0003] Chinese patent CN201810252703.1 confirms that it provides a pinless stapler, including a bottom cover and a base. Although this device solves the problem of recycled paper mixed with heavy metals, the pins do not penetrate the paper layers, and the internal stress between the paper layers is insufficient to support the paper layers to stick together. Too many bound paper layers and long-term placement can easily cause the paper layers to fall off, resulting in a limit on the number of sheets of paper to be stapled, and it cannot be widely used. Summary of the invention

[0004] The object of the present invention is to solve the above problems to at least a certain extent. To this end, the present invention provides an environmentally friendly stapler.

[0015] Figure 2 It is a cross-sectional structural schematic diagram of the utility model;

[0016] Figure 3 It is a schematic diagram of the exploded structure of the utility model; Specific implementation methods

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0018] like Figure 1 , 2 As shown in Figure 3, an environmentally friendly stapler includes a stapler 1 and a raised wooden block 2 that can cooperate with each other to perform stapling work, and is characterized in that: the stapler 1 is placed above the raised wooden block 2, wherein the stapler 1 includes a transmission mechanism 3 and a follower assembly 4, the transmission mechanism 3 is provided with an electromagnet mechanism 5 and a needle pressing assembly 6, and the follower assembly 4 is provided with a crescent belt 41 and a gear 42 for a straight stapler 7.

[0019] The utility model provides a straight-stitching staple 7 made of PLA as a binding consumable, provides a crescent-shaped arc-shaped toothed extrusion and storage straight-stitching staple 7 arranged on the outer ring of a crescent-shaped belt 41, utilizes an electromagnet mechanism 5 to drive a needle pressing assembly 6, and during the process, the needle pressing assembly 6 drives the crescent-shaped belt 41 to complete binding and refilling. Through this transmission system, the straight-stitching staple 7 can replace ferroalloy staples for binding, and the recycled paper does not contain heavy metals; and the product stapler 1 and the padding wooden block 2 are separately arranged and driven by the electromagnet mechanism 5, thereby expanding the binding flexibility and the thickness of the paper layer.

[0020] like Figure 2 , 3 As shown, a limit groove 13 of the needle pressing assembly 6 extends upward from the lower end of the left and right circular bin shells 11 of the stapler 1, the inner ring of the crescent belt 41 is provided with a tooth shape that cooperates with the transmission of the gear 42, and the outer ring of the crescent belt 41 is provided with a crescent arc tooth shape for storing and squeezing the straight stapler 7. The purpose of squeezing the straight staple 7 is to reserve internal stress for the straight staple 7 before binding so that it can rebound after binding, and to limit the straight staple 7 from falling off the paper layer by rebounding and straightening.

[0021] The square housing 12 of the stapler 1 is provided with three rows and two columns of support rod mounting holes 14 symmetrically distributed front to back. A pair of support rods 15 for supporting gears 42 are provided in the support rod mounting holes 14. The support rods 15 are provided to support the gears 42 so as to realize the binding and refilling of the straight staples 7 in the crescent belt 41.

[0022] The electromagnet mechanism 5 is provided with a rivet reset spring 8 and a rivet 9, and a circular through hole 51 and an annular groove 52 are provided in the middle of the electromagnet mechanism 5. A button battery 53 is provided in the circular through hole 51, and a copper wire 54 wound around a column is provided in the annular groove 52. When power is on, the rivet 9 will be attracted by the copper wire and enter the circular through hole 51, and at the same time compress the rivet reset spring 8. When power is off, the rivet reset spring 8 releases its internal stress, pushes the rivet 9 forward, and hits the pressure needle tip groove 61, thereby realizing the transmission work of the electromagnet mechanism 5.

[0023] A square needle loading hole 17 is provided at the top of the stapler 1 for filling the straight stapler 7, a square needle outlet hole 18 is provided in the center of the bottom plate 16 of the stapler 1 for passing through the needle tip groove 61, and the bottom plate 16 is provided with a needle pressing reset spring 19 corresponding to the left and right round bin shells 11 for the needle tip groove 61 to rebound after the needle is pressed. The needle tip groove 61 moves forward due to the advancement of the rivet 9, thereby compressing the needle pressing reset spring 19. When the electromagnet mechanism 5 is powered on again, the needle pressing reset spring 19 completely releases the internal stress, and the needle tip groove 61 performs a return movement.

[0024] A pressure needle tip groove 61 and a tip groove slide rail 62 are provided in the pressure needle assembly 6. An inverted cone-shaped support block 63 is provided at the end of the pressure needle tip groove 61 to limit the movement of the straight stitching needle 7 before binding is completed. The pressure needle tip groove 61 slides on the tip groove slide rail 62, and the straight stitching nail 7 for filling restricted by the crescent belt 41 is pressed against the tip groove slide rail 62, wherein the straight stitching nail 7 to be used for binding is pressed against the pressure needle tip groove 61, and is restricted by the inverted cone-shaped support block of the pressure needle tip groove 61, and passes through the paper layer together with its movement and stays, and then the pressure needle return spring 19 makes a return movement together with the pressure needle tip groove 62 to leave the paper layer.

[0025] A conical needle tip 71 and three strip-shaped barbs 72 are provided at both ends of the straight stapler 7. After being stapled into the paper layer, the originally bent straight stapler 7 will rebound and become straight. The resulting deformation will further cause the barbs on the straight stapler 7 to contact with the bottom of the paper layer and deform, thereby preventing the straight stapler 7 from falling off the paper layer by standing upright.

[0026] Combined with the drawings and the above display and description of the basic principles and main features of the utility model and the advantages of the utility model, the technical personnel in the industry should understand that the utility model is not limited by the above implementation method. The above implementation method and the specification only describe the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
