Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
As shown in Figure 1 to Figure 2, the utility model provides one kind and repairs pawl device comprising index dial 1 and several pull rod limit groups
Part 2, is provided with the through-hole 11 being evenly distributed on the index dial 1, the pull rod limitation unit 2 include pull hook 27, with pull hook 27
Integrally formed bolt draw bar 21, the pull rod limitation unit 2 are connected on through-hole 11 by pull hook 27 and are drawn by bolt
Bar 21 passes through the through-hole 11 and extends to outside index dial 1, wherein brute spring 24 is socketed on the bolt draw bar 21, it is described
24 one end of brute spring is in contact with index dial outer surface 12, the other end is fixed on bolt draw bar 21 by nut 22,
The external screw thread 28 being spirally connected with nut 22 is provided on the bolt draw bar 21, the pull hook 27 is whole to be drawn in rectangle and with bolt
Bar 21 is integrally formed, and is provided with vertical protrusion 26 on the pull hook 27, and the vertical protrusion 26 is fixed on pull hook 27, described to hang down
The groove 29 being cooperatively connected with scroll chuck 4 is additionally provided in straight protrusion 26；The vertical protrusion 26 is protected with 1 inner surface of index dial
Stay the gap 3 of adjustable 2 position of pull rod limitation unit, wherein the vertical protrusion 26 is cylinder；In the vertical protrusion 26
It is provided with for the first groove 25 with soft pawl positioning；21 end of bolt draw bar is provided with the first counterbore 23.
The utility model provides one kind and repairs pawl device, and there are three equally distributed pull rod limit groups for setting on the index dial 1
Part 2, wherein the angle of every two pull rod limit assembly 2 is 120 degree, such to be evenly distributed on index dial 1, effectively
The stability for stablizing index dial 1, improves reliability.
The utility model provides one kind and repairs pawl device, and manufacturing method is to hold the opposite of diameter using index dial 1 as soft claw clip
Foundation has beaten three through-holes 11 respectively on index dial 1, and the angle between through-hole 11 and through-hole 11 is according to three jaw self-centering cards
120 degree of angle manufactures of disk, are inserted into a bolt draw bar 21 respectively in each through-hole 11, then use brute spring 24 and nut
22 progress springs are fixed, consistent with scroll chuck since the angle in three holes of index dial is exactly 120 degree, so this is for behaviour
It can simply directly coincide with soft pawl when installation trims device for author, installation speed speeded, then due to three
Dog chuck is in loosening state before no holding parts, by the control of 24 one pulling force of row of brute spring in bolt draw bar 21
System, brute spring 5 both play the role of pulling force in entire mechanism, since brute spring 24 has certain elastic force limit,
Play the role of a soft pawl again in mechanism and repair choosing device and trimming range；
In addition the position between bolt draw bar 21 and nut 22 can also play a soft pawl diameter selection, therefore self-control is repaired
Choosing the range that trims of device, also to choose device than common repairing big；
