Description
Technical field
The utility model is related to a kind of stop nut locking pliers, especially a kind of stop nut locking pliers, is adapted to cup-shaped lock
Enclose the locking of stop nut.
Background technology
Stop nut can ensure that nut does not produce rotation after installing.A kind of structure therein produces change by cup-shaped retainer
Shape, to block be uniformly arranged outside stop nut and anti-loosening function is realized in axial locked groove.It has been uniformly arranged altogether outside general nut
Four locked grooves, cup-shaped retainer is using punch tool by the locked groove of retainer blastic deformation to nut.The size of this impulsive force and
The deformation of generation cannot be controlled accurately, there is connection loosing and retainer occurs the assembling risk of crackle etc..
The content of the invention
The purpose of this utility model is to provide a kind of stop nut locking pliers, it is possible to achieve without impulsive force work, it is possible to
Control the deflection of cup-shaped retainer, it is ensured that the functional reliability of stop nut groove.
Concrete technical scheme of the present utility model is that described stop nut locking pliers include caliper, detent mechanism, described
Caliper include clamp handle and jaw, vice jaw part portion is located at the outer rim of cup-shaped retainer and can make the deformation of cup-shaped retainer, detent mechanism
Including guide plate, locating shaft, spacer pin is symmetrically arranged with jaw, is symmetrically arranged with kidney slot on guide plate, the kidney slot of guide plate with
Spacer pin is engaged, and guide plate is arranged on jaw, and the track of spacer pin is set when described kidney slot is opened and closed along jaw, kidney-shaped
Groove limits the opening and closing amount of jaw；One end of locating shaft is fixedly connected in the middle part of guide plate, locating shaft is vertically arranged with guide plate, positioned
The other end of axle is provided with the angular pin being engaged with stop nut locked groove, described angular pin with stop nut end face with merging
With jaw interlaced arrangement.
The position coordinated with stop nut end face on described locating shaft is additionally provided with prolongs with stop nut minor diameter fit
Extending portion.
Extension spring is provided with described jaw, extension spring keeps jaw minimum state in its natural state.
Described locating shaft is coordinated on guide plate by square groove, and cooperation position is provided with straight pin.
The utility model stop nut locking pliers on guide plate by setting stopper slot, it is ensured that jaw opens and closes at
In the scope specified, it is to avoid the unexpected gouge and locking deformation that are caused to part into small space are excessive and produce retainer
Crackle.Tension spring is placed between caliper rotating pin and guide plate, and operator overcomes less pulling force i.e. expansible or clutches pincers
Mouthful, while also ensureing that caliper is in closure state all the time under non-working condition.Protected by using locating shaft and angular latch structure
Demonstrate,prove the accuracy of jaw position.Meanwhile, when needing the stop nut to different size to lock, can be easily to localization machine
Structure carries out replacing and uses, wide using scope, easy to operate.The utility model does not need impulsive force in use, and ensure that
The controllability reinforced during locking, reduces the hidden danger of quality that impulsive force is produced to assembling.

Fig. 2 is structural representation of the present utility model；
Fig. 3 is the A direction views of Fig. 2；
Fig. 4 is the B-B views of Fig. 2.
Specific embodiment
As illustrated, stop nut locking pliers include caliper, detent mechanism, described caliper includes clamp handle 1 and jaw, pincers
Mouth end is located at the outer rim of cup-shaped retainer and can deform cup-shaped retainer, and detent mechanism includes guide plate 6, locating shaft 8, on jaw
Spacer pin 5 is symmetrically arranged with, kidney slot is symmetrically arranged with guide plate 6, the kidney slot of guide plate 6 is engaged with spacer pin 5, makes guide plate
6 are arranged on jaw, and the track of spacer pin 5 is set when described kidney slot is opened and closed along jaw, and kidney slot limits opening for jaw
The amount of closing；The middle part of guide plate 6 is fixedly connected one end of locating shaft 8, and locating shaft 8 is vertically arranged with guide plate 6, the other end of locating shaft 8
The angular pin 9 being engaged with stop nut locked groove is provided with merging with stop nut end face, described angular pin 9 is handed over jaw
Mistake arrangement.
The position coordinated with stop nut end face on described locating shaft 8 is additionally provided with prolongs with stop nut minor diameter fit
Extending portion.
Extension spring 4 is provided with described jaw, extension spring 4 keeps jaw minimum state in its natural state.
Described locating shaft 8 is coordinated on guide plate 6 by square groove, and cooperation position is provided with straight pin 7.
During work, the caliper of hand-held locking pliers, jaw is opened to the outer rim of cup-shaped retainer, by the angular pin 9 on locating shaft 8
Insert in the locked groove of stop nut, while end face is leaned against on the end face of assembled shaft, hold clamp handle position, noted while slow reinforcing
Anticipate the deformation state of cup-shaped retainer, until the deformation of cup-shaped retainer in place or spacer pin 5 reach gain bottom untill.
