Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
As shown in fig. 1 to 9, the heavy stapler comprises a base 1 and a scale assembly 10 of the stapler, wherein a strip-shaped hole 11 is formed in the middle of the base 1, scales are marked on the upper end surface of the base 1 and on the left side and the right side of the strip-shaped hole 11, and the scale assembly 10 is arranged on the base 1 in a manner of sliding back and forth along the strip-shaped hole 11 and used for adjusting the paper feeding depth; the scale component 10 comprises a scale 2, a scale seat 3, a scale switch 4 and a top block 5, the scale 2 is erected above a base 1, the middle part of the upper end of the scale 2 is concavely provided with a notch 20 convenient for a pressure head of a stapler to press down, the bottom of the scale 2 penetrates through a strip-shaped hole to be fixedly connected with the scale seat below the base and can slide back and forth along the strip-shaped hole, the middle part of the lower end surface of the scale 2 is convexly provided with a connecting column 24, the scale seat 3 is a square plate with the size larger than the width of the strip-shaped hole 11, the scale seat 3 is positioned on the lower end surface of the base 1, the middle part of the scale seat 3 is formed with a bulge part 31 corresponding to the connecting column 24, the bulge part 31 is provided with a connecting hole corresponding to the connecting column 24, the scale 2 penetrates through the strip-shaped hole 11 to be inserted into the connecting hole through the connecting column 24 and is fixed with the scale seat, the ejector block 5 is arranged on the right side of the upper end of the scale 2 in a left-right sliding mode, so that the stapler cannot be pressed down and plays a role in withdrawing nails. Scale 2 is for the width matched with base 1, the outline is trapezoidal piece generally, scale 2's preceding terminal surface is vertical as the plane of dog, scale 2's the downward shaping of the left and right sides has the gliding border 23 of both sides cooperation counterbalance with base 1 about, scale 2's upper end right side shaping has the recess 22 that supplies kicking block 5 to put into and spacing gliding, recess 22 link up with breach 20 mutually, 20 left side bottom opening of scale 2 and upwards shaping have the appearance chamber 21 that supplies scale switch 4 to put into and control spacing gliding, set up the opening that supplies scale switch 4's button portion to stretch out on scale 2's the left surface. The principle of positioning of the scale switch 4 is such that: the inner wall of the strip-shaped hole 11 is positioned at one side of the scale switch 4 and is formed into a tooth surface 12, the bottom of the scale switch 4 extends inwards to form a convex tooth 41 which is engaged with the tooth surface 12 of the strip-shaped hole 11, the lower end surface of the scale 2 is formed with a concave part which is used for the convex tooth 41 of the scale switch 4 to insert and limit sliding, the convex tooth 41 is supported between the scale switch 4 and the inner wall of the accommodating cavity 21 of the scale switch 2 and is provided with a spring 6 which is always engaged and locked with the strip-shaped hole 11, the cross section outline of the scale switch 4 is basically rectangular, the length of the accommodating cavity 21 of the scale 2 is larger than that of the scale switch 4, when the scale switch 4 slides inwards to the bottom, the convex tooth 41 just breaks away from the tooth surface 12 of the strip-shaped hole 11, the width of the scale switch 4 is larger than the width of the left side opening of the scale switch 2, the opening is a rectangular opening, the button, a spring hole is formed in the scale switch 4, one end of the spring 6 is supported and arranged on the inner wall of the accommodating cavity 21 of the scale 2, and the other end of the spring is inserted into the spring hole, so that the scale switch 4 has the tendency of always moving outwards to enable the convex teeth 41 to be meshed and locked with the tooth surface 12 of the strip-shaped hole 11.
The kicking block 5 is the right angle trapezoidal piece corresponding with the right side of scale 2, kicking block 5 sets up and meets with the outer terminal surface smoothness of scale 2 on the upper end right side of scale 2, the bottom surface epirelief of the recess 22 of scale 2 is equipped with T shape direction muscle 26, the bottom of kicking block 5 is equipped with corresponding guide way 51, the protruding bump 52 that is equipped with in bottom of kicking block 5, corresponding fluting and gear muscle 25 have been seted up on the bottom surface of the recess 22 of scale 2, make kicking block 5 have the damping to feel also can not drop, the bottom surface of the breach 20 of scale 2 is low for the front portion, the inclined plane structure of rear portion branch height, just so play limiting displacement to the front end of kicking block 5. For the convenience of operation, the upper end face of the top block 5 is provided with a solid arrow mark sliding inwards, and the left side of the upper end of the scale 2 is provided with a solid arrow mark sliding inwards of the scale switch 4.
When the ruler assembly is used, the button part of the ruler switch 4 is pressed by a hand to push inwards, so that the convex teeth 41 are separated from the tooth surface 12, the ruler assembly 10 can be moved forwards and backwards to reach the required paper feeding depth, after the ruler assembly is adjusted to be in place, the ruler switch 4 is loosened, the ruler switch 4 is reset under the action of the spring 6 and is meshed with the tooth surface 12 to lock the ruler assembly 10, and the operation is very convenient; when the staple withdrawing is needed, the ejector block 5 is pushed inwards, so that the ejector block 5 moves to the position of the notch 20, and the stapler cannot be pressed down to withdraw the staple.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the technical principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
