Description

Staple remover

Technical Field

The utility model relates to an office supply.

Background

At present, with the complexity of economic activities, a plurality of bound materials need to be decomposed, and a staple claw exists at present, but the staple claw is relatively labor-consuming, especially when used by women.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the technical problem who solves: how to provide a labor-saving staple remover.

The technical scheme of the utility model specifically does:

The utility model provides a staple nail puller, includes upper handle and lower handle, and upper handle is articulated through the round pin axle with lower handle, and the upper handle is last holding head in the part of round pin axle front end, goes up the tip of holding head and fixes the tool bit, and lower handle is holding head down in the part of round pin axle front end, tool bit under the tip of lower holding head is fixed. The upper cutter head and the lower cutter head both extend towards the inner side, the inner ends of the upper cutter head and the lower cutter head are mutually meshed blades, and the thickness from one side of each blade to the other side of each blade is gradually increased. Go up the supporting head and fix the bracing piece to the skew outside, the end fixing supporting seat of bracing piece.

The cutting edge of the upper cutter head protrudes outwards, and the cutting edge of the lower cutter head is sunken inwards.

The supporting seat is made of rubber materials, and the lower surface of the supporting seat is a part of a spherical surface.

Compared with the prior art, the technical effect of the utility model is that, the utility model discloses the design has the bracing piece, and it can regard as the fulcrum, is utilizing the handle as the lever, can pry the staple, and is more laborsaving.

Detailed Description

Referring to fig. 1 to 3, a staple remover comprises an upper handle 10 and a lower handle 20, wherein the upper handle 10 is hinged to the lower handle 20 through a pin shaft 30, the upper handle 10 is an upper clamping head 11 at the front end of the pin shaft 30, the end of the upper clamping head 11 is fixed with an upper tool bit 12, the lower handle 20 is a lower clamping head 21 at the front end of the pin shaft 30, and the end of the lower clamping head 21 is fixed with a lower tool bit 22.

The upper cutter head 12 and the lower cutter head 22 both extend inwards, the inner ends of the upper cutter head and the lower cutter head are mutually engaged cutting edges 14, and the thickness of the cutting edges 14 is gradually increased from one side to the other side.

The upper clamping head 11 fixes the support rod 40 in a slanting outward direction, and the end of the support rod 40 fixes the support base 41.

To facilitate shearing of the staple back staple (also known as a short leg), the blade edge 14 of the upper blade 12 is convex and the blade edge 14 of the lower blade 22 is concave.

In order for the supporting base 41 to scratch the document, the supporting base 41 is made of a rubber material, and the lower surface thereof is a part of a spherical surface (see reference numeral 42 of fig. 5).

other content participates in the prior art.

Referring to fig. 1-5, especially fig. 4, a staple 51 is provided on a document 50, if the staple is bound, the upper tool bit 12 and the lower tool bit 22 can be extended into the gap from the two sides of the gap between the staple and the document (front surface) respectively until the two tool bits are engaged, so that the staple is enclosed in the space between the upper tool bit 12, the lower tool bit 22, the upper clamping head 11 and the lower clamping head 21, then the entire nail puller rotates towards one side of the supporting seat 41, the supporting seat 41 is contacted with the document, the nail puller continues to rotate, the supporting seat 41 plays a role of a fulcrum, the upper handle 10 and the upper clamping head 11 form a lever, and the staple 51 is levered out by the lever, which is labor-saving.

If the staple is firm, the method can not take out the staple, and the nail shearing operation is firstly carried out: the back of the document is upward, the upper cutter head 12 and the lower cutter head 22 are clamped on two sides of the short nail (also called short leg), and the short nail (also called short leg) is cut off by holding the two handles.

When the two staples (also called short legs) are sheared off, the staple 51 is levered out by the method, so that the staple is very easy and suitable for women.

While the preferred embodiments of the present invention have been described, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the general inventive concept, and it is intended to cover all such changes and modifications as fall within the true spirit and scope of the invention.
