Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

The quick-release insert rod shown in fig. 1 to 6 includes:

the elastic body comprises a rod body 10 and a head 20, wherein one end of the rod body 10 is connected with one end of the head 20, an opening structure 30 is arranged on the head 20, the opening structure 30 extends from the center of the end face of the head 20 to the axial side face of the head 20 and is used for dividing the head 20 into a plurality of elastic bodies 21 with equal size, and the elastic bodies 21 can be close to each other.

Through set up open structure 30 on the head 20 at the inserts pole, cut apart into a plurality of elastomer 21 structures with the head 20 of inserts pole, when carrying out the assembly of inserts 01, can directly insert inserts 01 with head 20, elastomer 21 is close to each other and limits in the hole of inserts 01, under the frictional force effect of elastomer 21 and hole helicitic texture, can not take off easily, after injection moulding accomplishes, can extract the inserts pole from the finished piece after burying, thereby realized the process of installing and removing fast, and the production efficiency is improved.

It should be noted that the elastic body 21 can be made of a material such as phosphor bronze, which has high corrosion resistance and wear resistance, and also has high toughness and elasticity, so that the elastic bodies 21 can be close to each other.

Specifically, the diameter of the head 20 is slightly larger than the inner hole diameter of the corresponding insert 01, a chamfer is arranged at the end of the head 20 away from the rod body 10, the head 20 of the insert rod is conveniently inserted into the inner hole of the insert 01 through the chamfer, and the diameter of the head 20 is slightly larger than the inner hole diameter of the corresponding insert 01, so that in the process of inserting the inner hole of the insert 01, the thread structure of the inner hole of the insert 01 acts on the elastic body 21, the elastic body 21 is stressed to be close to and shrunk, the shrunk head 20 can be smoothly inserted into the inner hole of the corresponding insert 01, and due to the elastic effect, pressure action is generated on the inner hole wall of the insert 01, friction force is formed, and the insert rod cannot be easily separated from the inner hole of the insert 01.

Wherein, the central axes of the rod body 10 and the head 20 are positioned on the same straight line, so as to ensure the coaxiality of connection.

As one of the arrangement forms, the opening structure 30 is a trisected trough body 30a, an included angle between two adjacent trough bodies 30a is 120 °, that is, 3 elastic bodies 21 are formed, and the elastic bodies 21 and the trough bodies 30a are arranged at intervals.

As another arrangement form, the opening structure 30 is a cross-shaped slot body 30a, an included angle between the two slot bodies 30a is 90 °, that is, 4 elastic bodies 21 are formed, and the elastic bodies 21 and the slot bodies 30a are arranged at intervals.

Of course, the arrangement form of the opening structure 30 is not particularly limited in the present application, and the above-mentioned only examples of the arrangement form of the opening structure 30, but not limited to the above two arrangement forms, can achieve the effects of the present invention; because the more the cell bodies 30a are, the more the space that the elastomer 21 finished piece can be close to each other is, therefore the less the required plug force is, the more easily the insert pole is deviate from the inner hole of the insert 01, therefore, the cell bodies 30a need to be set according to the demand of actual plug, and under general conditions, the cell bodies 30a adopting the two trisections and the cross cell bodies 30a can meet the use demand.

On the basis of the above embodiment, each elastic body 21 includes the first separating surface 21a and the second separating surface 21b, the first separating surface 21a is disposed opposite to the second separating surface 21b of the adjacent elastic body 21, when the head 20 is inserted into the inner hole of the insert 01, the first separating surface 21a and the second separating surface 21b of the adjacent elastic body 21 are close to each other, and the amount of movement of one end departing from the rod 10 is greater than the amount of movement of one end close to the rod 10, i.e. the amount of movement of the connecting position of the head 20 and the rod 10 is the smallest, the pressure action on the inside of the insert 01 is the largest, thereby ensuring that the insert rod cannot be released from the insert 01.

In order to prevent the elastic bodies 21 from being damaged by force in the inserting process, an arc-shaped portion 30b is formed at one end of the groove body 30a close to the rod body 10, one end of the arc-shaped portion 30b is connected with the first separating surface 21a, and the other end of the arc-shaped portion is connected with the second separating surface 21b of the adjacent elastic body 21, that is, the two adjacent elastic body 21 pieces form smooth arc-shaped transition connection.

On the basis of the above-mentioned embodiment, body of rod 10 includes shoulder 11, connecting portion 12 and afterbody 13, shoulder 11 one end is connected with head 20, the other end is connected with the one end of connecting portion 12, afterbody 13 is connected to the other end of connecting portion 12, shoulder 11, the axis of connecting portion 12 and afterbody 13 all is located same straight line, shoulder 11 has location and axial limiting displacement, when needs are pulled out the inserts pole from inserts 01, only need catch afterbody 13, and along the axis to the direction application of force that is from head 20 away from can.

The diameter of the shoulder part 11 is larger than that of the head part 20, so that the situation that materials are drilled between the contact end faces of the insert rod and the insert 01 in the injection molding process is avoided, and the molding precision of a workpiece is guaranteed.

It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
