Between 43, to help main shaft 51 to reset.In the present embodiment, elastic component 60 is spring.
Please refer to Fig. 4 in the lump again, when cylinder 100 works, extraneous gas enters cylinder body 10 by the first passage 114 first
Host cavity 111 in.When gas pressure intensity reaches preset value, piston 20 is promoted to be moved towards bonnet 13.Piston rod 30 is lived
Plug 20 drives and is moved towards bonnet 13.The also slip in slide slot 32 simultaneously of fixture 52.Now, directional 123 is in gathering sill
Slide in 31 spire, piston rod 30 is directed part 123 while moving towards bonnet 13 and drives and starts to rotate.
Meanwhile, main shaft 51 is driven by piston rod 30 and is rotated around same axis.In the present embodiment, main shaft 51 is in same level
Rotate in face.Then, when 123 motion straight trough portion of directional, piston rod 30 stops the rotation motion, and main shaft 51 is also corresponding
Stopping rotates.Now, the slide slot 32 of piston rod 30 is contacted away from the end of piston 20 with fixture 52, it is impossible to continued
Slide, the relative slide slot 32 of main shaft 51 is fixed.The axially-movable of piston rod 30 drives main shaft 51 to make axially-movable, so as to compress bullet
Property part 60.In present embodiment, cylinder 100 realizes main shaft 51 and first rotates and is re-directed towards the motion that bonnet 13 is pushed, and it pushes row
Stroke of the journey less than piston rod 30.
When extraneous gas enters the host cavity 111 of cylinder body 10 by the second passage 115, while the first passage 114 pairs
Outer deflation.When gas pressure intensity reaches preset value, piston 20 is promoted to be moved towards guide 40.Directional 123 is first in leading
Move into the straight trough portion of groove 31, piston rod 30 makees axially-movable.Now, the elastic component 60 for being compressed is main to the applying power of main shaft 51
Axle 51 is towards its initial position motion.Then, when directional 123 moves to spire, piston rod 30 is being moved towards protecgulum 12
Meanwhile, it is driven and starts to rotate.Meanwhile, main shaft 51 is driven by piston rod 30 and is rotated around same axis.Now,
Because fixture 52 slides in slide slot 32, the opposing pistons bar 30 of main shaft 51 slides, and main shaft 51 only does in same level
Rotary motion, does not continue to axially move.
The simple structure of cylinder provided by the utility model 100, and due to being provided with slide slot 32, phase on piston rod 30
The fixture 52 that can be slided in slide slot 32 is installed so that main shaft 51 first rotates and pushes again, and then makes on the main shaft 51 answered
Obtain main shaft 51 pushes stroke of the stroke less than piston rod 30.Therefore, there is no need to the headspace in cylinder body 10, the body of cylinder 100
Product is less, can be applied to small space.
This utility model is not restricted to described in description and embodiment, therefore for the personnel of familiar field
For be easily achieved additional advantage and modification, therefore in the general concept limited without departing substantially from claim and equivalency range
Spirit and scope in the case of, this utility model be not limited to specific details, representational equipment and shown here as with retouch
The examples shown stated.
