Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.

In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "fixed" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

Referring to fig. 1 to 2, an embodiment of the present invention provides a combination spring screw, including a rod body 10 and a spring member 30;

specifically, the rod body 10 can be inserted into the components to be connected, so as to connect the components to be connected together; the rod 10 is provided with a limiting member 20.

The spring member 30 is sleeved outside the rod body 10, and one end of the spring member is limited on the rod body 10 by the limiting member 20.

That is to say, through locating part 20, can establish spring part 30 cover and install outside the body of rod 10, like this, when utilizing the body of rod 10 will take the adapting unit to assemble, the elastic component is located the body of rod 10 and treats between the adapting unit to be in the compression state, and then, when the in-process of equipment work produced the vibration, under the elastic action of elastic component, the body of rod 10 is difficult for producing resonance with equipment, and is corresponding, also is difficult for not hard up because of the equipment vibration.

Advantageously, in one embodiment of the present invention, the rod body 10 comprises a screwing portion 11, a connecting section 12 and a threaded section 13;

a screwing groove matched with a screwing piece is formed in one side face of the screwing part 11, the connecting section 12 is connected to the other side face of the screwing part 11, the limiting piece 20 is arranged on the outer peripheral wall of the connecting section 12, and the thread section 13 is connected with the tail end of the connecting section 12;

the spring element 30 is sleeved outside the connecting section 12, and one end of the spring element is limited between the limiting element 20 and the screwing part 11.

That is, the connecting section 12 is disposed on the other side of the screwing portion 11 and connected to the threaded section 13, and when in use, the rod body 10 is screwed by the screwing member adapted to the screwing groove, so that the threaded section 13 can be driven to connect to the component to be connected, and the component to be connected is assembled together. And spring part 30 cover is established outside linkage segment 12, consequently for spring part 30 is compressed and support and is held on treating adapting unit, so, through the effect of spring part 30, just also can avoid the utility model discloses follow equipment vibration and not hard up.

Advantageously, in an embodiment of the present invention, the spring element 30 includes a first end 31 and a second end 32, the first end 31 is defined between the limiting member 20 and the screw part 11, and the inner diameter of the spring element 30 gradually increases from the first end 31 to the second end 32;

the outer diameter of the connecting section 12 is smaller than the inner diameter of the first end 31, and the outer diameter of the limiting member 20 is larger than the inner diameter of the first end 31.

Therefore, the inner diameter of the first end 31 is larger than the outer diameter of the connecting section 12 and smaller than the outer diameter of the limiting member 20, so that the first end 31 of the spring member 30 can be limited between the limiting member 20 and the screwing portion 11 and is not easy to fall off, and further the spring member 30 can be fixed, and the inner diameter of the spring member 30 is gradually increased from the first end 31 to the second end 32, so that a gap is formed between the second end 32 of the spring member 30 and the connecting section 12, and therefore, when the spring member 30 is used, after being compressed by a force, the second end 32 is not easy to contact and rub with the connecting section 12, and accordingly, the plating layer outside the connecting section 12 is not easy to damage.

Advantageously, in another embodiment of the present invention, the outer diameter of the end of the connecting section 12 remote from the screw part 11 is smaller than the outer diameter of the end close to the screw part 11.

In this way, the distance between the connecting section 12 and the second end 32 of the spring element 30 is further increased, and therefore, the spring element 30 can be further prevented from damaging the connecting section 12 in use.

Advantageously, in some embodiments of the invention, the screw groove is in the shape of a "straight line".

Preferably, the screw groove may also be in a cross shape.

Of course, different shapes of screw grooves may require the use of differently shaped tightening members, which may be screwdrivers or the like.

Advantageously, in other embodiments of the present invention, the connecting section 12 is integrally formed with the threaded section 13.

So for linkage segment 12 and screw thread section 13 structure as an organic whole, it is corresponding, the joint strength between the two is also great, and the reliability is higher, and then makes long service life, is favorable to the use.

Finally, it is necessary to supplement that a boss is arranged on the side wall of the screwing part 11, the boss is provided with the screwing groove, meanwhile, a cap is detachably arranged outside the boss, the cap is also provided with the screwing groove, and the shape of the screwing groove on the cap is different from that of the screwing groove on the boss, for example, the screwing groove on the boss is in a shape of Chinese character 'yi', the screwing groove on the cap can be in a shape of Chinese character 'ten', so that when the screwing piece is in a shape of Chinese character 'yi', the cap can be taken off, then the screwing piece in a shape of Chinese character 'yi' is inserted into the screwing groove on the boss for operation, then the cap is assembled, and the screwing groove on the boss can be closed by the cap, so as to avoid the entry of foreign matters; when the tightening piece is in a cross shape, the cross-shaped tightening piece can be directly inserted into the screwing groove on the cap for use, so that the device has better applicability.
