In figure：Hexagon socket head cap screw 1, screw thread 2, piston pin body 3, mandril 4, mounting hole 5, fixed block 6, the first spring 7, limit
Position plate 8, jacking block 9, second spring 10, through hole 11.
Embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
With reference to Fig. 1-2, a kind of Novel piston pin, including piston pin body 3, the inside of the piston pin body 3 offer
Through hole 11, is provided with two mandrils 4 in the through hole 11, two mandrils 4 pass through two first close to the middle part of through hole 11
Spring 7 connects, and two first springs 7 are respectively and fixedly installed to one end both sides of two mandrils 4, and two the first springs 7
It is easy to use easy to fix positioned at the both sides of second spring 10, prevent from coming off.
As shown in Figure 1, when hexagon socket head cap screw 1 is installed on piston pin body 3, the first spring 7 is in the case where two mandrils 4 act on
In contraction state, while two mandrils 4 push out two fixed blocks 6, fixed block 6 is connected with connecting rod, ensure piston
It with connecting rod connective stability, can prevent piston pin from coming off, improve service life.
The piston pin body 3 is connected with hexagon socket head cap screw 1 close to the both ends of through hole 11 by screw thread 2, described in two
