The end of thread is embedded in the annular groove of fixing axle, by fixed shaft locking；The bottom of adjusting rod is equipped with threaded hole two；Fixing axle it is upper
End is threadedly coupled by external screw thread with the threaded hole two on adjusting rod；Nut is threaded between fixing axle and adjusting rod；
Further, the upper end of the stretching bracket is equipped with draft cylinder；The bottom for drawing high bracket is equipped with sealing cylinder；It draws
The tailpiece of the piston rod and moving mass for stretching cylinder are sequentially connected；The lower part of moving mass is equipped with pull rod；
Further, one end of moving mass is fixed with attachment cap；Attachment cap is equipped with buffer；Buffer is same with adjusting rod
Axis.
After adopting the above structure, the utility model has the beneficial effect that a kind of stretch rod limit described in the utility model is fast
It changes planes structure, performance is stable, replacement is quick, easy to adjust, and has many advantages, such as that structure is simple, setting is reasonable, low manufacture cost.
Detailed description of the invention

Specific embodiment
With reference to the accompanying drawing, the utility model is further described.
Referring to shown in Fig. 1-2, present embodiment the technical solution adopted is that: it includes fixed block 4, fixing axle 1, ten
Word handle 12, adjusting rod 3；The fixed block 4 is fixed below the middle part for stretching bracket 9；The upper end of fixed block 4 is equipped with counterbore
4-2；One 4-1 of threaded hole being connected to counterbore 4-2 is equipped in the middle part of the side of fixed block 4；The upper end of fixing axle 1 is equipped with external screw thread 1-
2；The lower end of fixing axle 1 is equipped with annular groove 1-1；And it is plugged in the counterbore 4-2 of 4 upper end of fixed block；Palm grip knob 12 and solid
Determine the one 4-1 connection of threaded hole of 4 side of block, the end of thread of palm grip knob 12 is embedded in the annular groove 1-1 of fixing axle, will fix
Axis 1 is locked, and guarantees that it will not shake；The bottom of adjusting rod 3 is equipped with two 3-1 of threaded hole；The upper end of fixing axle 1 passes through external screw thread 1-
2 are threadedly coupled with two 3-1 of threaded hole on adjusting rod 3；Nut 2 is threaded between fixing axle 1 and adjusting rod 3；2 spiral shell of nut
Line is connected to the upper end of fixing axle 1, plays the role of loosening, and the length variation of adjusting rod 3 can be used to control the stroke of stretch rod；
Referring to shown in Fig. 2, the upper end of the stretching bracket 9 is equipped with draft cylinder 8；The bottom for drawing high bracket 9 is equipped with envelope
Mouth cylinder 5；The tailpiece of the piston rod and moving mass 7 of draft cylinder 8 are sequentially connected；The lower part of moving mass 7 is equipped with pull rod 6；
Referring to shown in Fig. 2, one end of moving mass 7 is fixed with attachment cap 11；Attachment cap 11 is equipped with buffer 10；Buffer
10 is coaxial with adjusting rod 3.
The working principle of the present embodiment is as follows: the piston rod in draft cylinder 8 pushes down on when bottle base starts blowing
Moving mass 7 is sent, pull rod 6 is moved downward, while being passed through high pressure gas into sealing cylinder 5, the piston in sealing cylinder 5 is driven to transport downwards
It moves and completes to seal.When buffer 10 is contacted with adjusting rod 3 and tends to be static by of short duration buffering, bottle base blowing terminates,
Pull rod 6 is lifted up with the piston rod contraction of draft cylinder 8, is blown bottle process and is completed.
When the bottle-type of blowing changes and the length of adjusting rod 3 needs to change, unscrew palm grip knob 12, by adjusting rod 3, spiral shell
The limit assembly that mother 2 and fixing axle 1 form takes out, and is inserted into the limit assembly for needing replacing size, tightens palm grip knob 12,
Complete the replacement of limit assembly.
The above is only to illustrate the technical solution of the utility model, rather than limits those of ordinary skill in the art couple
The other modifications or equivalent replacement that the technical solution of the utility model is made, without departing from technical solutions of the utility model
Spirit and scope should all cover in the scope of the claims of the utility model.
