Description
The technical field is as follows:
the utility model belongs to the technical field of the screw rod, especially, relate to a novel clamping screw.
Background art:
among the clamping screw wide application in the life, some fixed connector for the clamping screw pole head on the existing market are mostly solid construction, pull to twist the mode and all fix the pole head through the spanner, then twist soon, need prepare corresponding spanner according to the size and the shape of screw pole head when twisting, and are very inconvenient.
The utility model has the following contents:
the utility model aims at the above problem, a novel clamping screw is provided.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a novel fixing screw, includes the pole head and the body of rod, the pole head is hollow circular cylinder, pole head upper portion surface equidistance is equipped with a series of circular through-holes, the inside bottom surface equidistance of pole head is equipped with a series of springs, the one-to-one about the position of spring and the position of through-hole, every upper portion of spring all is equipped with the pillar of cylinder structure, inside the pole head was located to the pillar half, half passed the through-hole and exposed in pole head upper portion surface, the pole head lower part is equipped with the body of rod, the body of rod is the cylinder structure, the vertical center pin of the body of rod and the vertical center pin of pole head are on a.
The distance between the through hole and the through hole is not less than the diameter of the through hole.
In the novel fixing screw, the diameter of the pillar is equal to that of the through hole.
In the novel fixing screw, the length of the strut is equal to the thickness of the cavity in the club head, and is equal to twice the length of the spring.
In the novel fixing screw, the length of the threaded section is greater than that of the non-threaded section.
The utility model has the advantages that: because all be equipped with the spring below every pillar of screw rod pole head, every can all independently stretch out and draw back, so when fastening or taking off the screw rod with the spanner, to the spanner of arbitrary size and shape, at the in-process that the spanner head pushed down, all contract with every pillar of spanner head contact, the pillar that is not pressed keeps the original state and tightly surrounds around the spanner head or spanner head intermediate space, and then steadily overlaps firmly the spanner head, thereby lock the spanner head when the rotatory fastening of spanner or the pine take off the screw rod, make the operation of twisting of screw rod more convenient.
Description of the drawings:
the invention will be further explained with reference to the following description and examples.
FIG. 1 is a schematic view of a screw configuration;
fig. 2 is a top view of the screw.
In the drawings, 1. a head; 2. a rod body; 21. a non-threaded section; 22. a threaded segment; 3. a spring; 4. a pillar; 5. and a through hole.
The specific implementation mode is as follows:
the following is a specific embodiment of the present invention, and the technical solution of the present invention is further described with reference to the accompanying drawings.
Referring to the attached drawings, the utility model discloses a novel fixing screw, including the pole head 1 and the body of rod 2, pole head 1 is hollow circular cylinder, 1 upper portion surface equidistance of pole head is equipped with a series of circular through- holes 5, 1 inside bottom surface equidistance of pole head is equipped with a series of springs 3, the one-to-one about the position of spring 3 and through-hole 5's the position, every upper portion of spring 3 all is equipped with the pillar 4 of cylinder structure, inside pole head 1 was located to pillar 4 half, half passed through-hole 5 and exposed in 1 upper portion surface of pole head, 1 lower part of pole head is equipped with the body of rod 2, the body of rod 2 is the cylinder structure, the vertical center pin of the body of rod 2 and the vertical center pin of pole head 1 are on a straight line, 2 upper portions of the body of rod are non.
The utility model discloses an use flow: when the fixing screw is used for fixing, a wrench with any size and shape can be selected, the head of the wrench is placed on the pillar 4 of the club head 1, the head of the wrench is pressed downwards by hand until the head of the wrench is attached to the upper surface of the club head 1, and then the wrench is rotated to fasten or loosen the screw.
The utility model discloses an application principle: in the process of pressing the head of the wrench downwards, because the spring 3 is arranged below each strut 4, each strut 4 contacted with the head of the wrench shrinks in the process of pressing the head of the wrench downwards, the struts 4 which are not pressed are kept to be tightly enclosed around the head of the wrench, and a part of the struts 4 which are not pressed exist in the middle gap of the head of the wrench, so that the struts 4 which are not pressed around the head of the wrench or in the middle gap of the head of the wrench are in a shape matched with the head of the wrench, the head of the wrench is stably sleeved firmly, and the struts 4 which are not pressed lock the head of the wrench in the process of rotating and fastening or loosening a screw rod of the wrench.
The present invention is not limited to the above embodiments, and obvious changes can be made by those skilled in the art according to the description of the above embodiments, but all such changes are within the scope of the present invention.
