Description

Plastic draw-bar clamp

Technical Field

The utility model relates to a pole clamp technical field especially relates to a plastics pole clamp of taking out.

Background

The pull rod clamp can clamp and fix a thin object, the pull rod can be used only by being extracted when the object is clamped, and the steps of punching and binding are not needed, so that the use is very convenient. The draw-bar clamp is widely applied to environments such as schools, office environments, families and the like, and has a very remarkable sorting function for classified storage and storage of paper products such as various data, documents and the like.

However, when the existing draw bar clamp inserts the paper to be stored into the two clamping pieces of the draw bar clamp, the paper is difficult to be directly inserted into the middle of the two clamping pieces because the two clamping pieces are close to each other at the side far away from the clamp back. The user needs to slightly break the opening sides of the two clamping pieces before inserting the paper into the two clamping pieces smoothly, and the process is very troublesome. In addition, the two jaws may be deformed due to long-term use or expansion and contraction due to heat, and when the number of sheets of paper to be stored is small, the paper may slip out of the two jaws.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a plastics are taken out pole and are pressed from both sides, and the user need not break two clamping pieces off with the fingers and thumb the back and insert the paper in two clamping pieces again. A notch is formed in the port of the clamping piece on one side, so that a user can insert paper into the middle of the two clamping pieces more conveniently and quickly. In addition, the clip is arranged on the clip back to further fix the paper contained in the two clips, so that the paper is prevented from sliding out of the two clips and being lost.

The above technical purpose of the present invention can be achieved by the following technical solutions: the utility model provides a plastics pole clamp of taking out, includes the back of the clamp and is located the clamping piece of both sides about the back of the clamp, one side wherein the clamping piece top is provided with the breach, the breach enlarges gradually to the direction of keeping away from the back of the clamp, the inboard edge of breach is provided with arc chamfer one, the back of the clamp is close to the position of upper end and has seted up the mounting hole, be provided with the clip in the mounting hole, the mouth that presss from both sides of clip is towards two the opening direction of clamping piece.

Through the technical scheme, when the object is vertically inserted downwards into the clamping pieces on the two sides of the draw bar clamp, the object cannot be firstly contacted with the joint parts of the two clamping pieces, but is firstly inserted into the parts, close to the back of the clamp, of the two clamping pieces, and the clamping pieces on the two sides of the position are separated by a larger distance, so that the object can be smoothly inserted.

Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

The present invention will be described below with reference to fig. 1 to 5.

A plastic draw-bar clamp comprises a clamp back 1 and clamping pieces 2 positioned on the upper side and the lower side of the clamp back 1. The position of the clip back 1 near the lower end is provided with a baffle plate 14, and the baffle plate 14 is positioned between the clip pieces 2 at two sides. The worker inserts the document between the two jaws 2 and moves it downward, and the document is stopped by the stopper 14 and cannot move further downward when the document moves to the bottom of the draw bar clip. The lower end of the file is prevented from being exposed outside the lower end of the draw bar clamp due to the fact that the file moves downwards and exceeds the head, and wrinkles of the file exposed outside the draw bar clamp are prevented. The inner wall edge position that clip 2 kept away from back of the clamp 1 is provided with a plurality of hemisphere rubber convex blocks 13 along its length direction, and hemisphere rubber convex blocks 13 have certain elasticity, enable the clip 2 of both sides to carry out the centre gripping to the paper better. Wherein the top of the clamping piece 2 on one side is provided with a notch 3, the notch 3 is an arc-shaped notch 3, and the notch 3 is gradually enlarged towards the direction far away from the clamp back 1. When vertically and downwards inserted into the clamping pieces 2 at two sides of the draw bar clamp, an object is not firstly contacted with the joint parts of the two clamping pieces 2, but is firstly inserted into the parts of the two clamping pieces 2 close to the clamp back 1, and the clamping pieces 2 at two sides of the position are separated by a larger distance, so that the object can be smoothly inserted. When continuing inserting the object again in two clamping pieces 2, the object can strut the clamping piece 2 of both sides naturally to can not be blockked by the laminating position of two clamping pieces 2, make the object more easily the centre in the middle of two clamping pieces 2.

The edge of 3 inboards in breach is provided with arc chamfer one 4, and arc chamfer one 4 can the time paper downward along arc chamfer one 4 take the advantage of the situation downward when inserting, make paper male process more smooth. The cover is equipped with rubber protective sheath 7 on breach 3, and rubber protective sheath 7's upper end inside wall is provided with arc chamfer two 8. Rubber protective sheath 7 can play the guard action to breach 3, and rubber protective sheath 7 can prevent that the user from being scratched by breach 3 when using simultaneously.

The position of the clamp back 1 close to the upper end is provided with a mounting hole 5, a clamp 6 is arranged in the mounting hole 5, and the opening of the clamp 6 faces the opening direction of the two clamping pieces 2. When the paper is inserted into the two clamping pieces 2, the clamp 6 is opened, and the paper is completely inserted and then clamped at the upper end of the paper by using the clamp 6, so that the auxiliary clamping effect can be achieved. The paper is prevented from slipping out of the two clips 2 when the number of the stored paper is small. The clamp 6 comprises a fixing rod 9, two clamping pieces 10 and a torsion spring 11, wherein the fixing rod 9 is vertically arranged, and the upper end and the lower end of the fixing rod are fixed on the inner walls of the upper side and the lower side of the mounting hole 5. The two clamping pieces 10 are located on two sides of the fixing rod 9 and are rotatably connected with the fixing rod 9, the torsion spring 11 is sleeved on the fixing rod 9, and two ends of the torsion spring 11 are respectively fixed on the side walls of the two clamping pieces 10 close to the fixing rod 9. Under the action of the torsion spring 11, the ends of the two clamping sheets 10 far away from the clamp back 1 are clamped with each other, so that a good clamping effect is provided for paper between the two clamping sheets 10, and the paper is prevented from sliding out of the two clamping sheets 2. The inner walls of the two clamping sheets 10 far away from the clamp back 1 are provided with rubber pads 12, and the rubber pads 12 have certain flexibility and can prevent the clamp 6 from damaging the paper when clamping the paper.
