Lever 5 is rotated, the quantity for the second positioning groove 512 being arranged on lever 5 is identical as the quantity of positioning convex platform 402, positioning
It can be arranged in the axial sliding of the second positioning groove 512, swivel head 3 while boss 402 and often chimeric the second positioning groove 512
The quantity of the first positioning groove 312 be then greater than the quantity of positioning convex platform 402, guaranteeing that swivel head 3 rotates relative to lever 5
There can be positioning groove chimeric with positioning convex platform in the range of 0 ° -90 °, the first different positioning grooves 312 is in 3 phase of swivel head
To chimeric with positioning convex platform 402 respectively after the rotation respective angles of lever 5.
For the ease of the assembly of 5 internal structure of swivel head 3 and lever, swivel head 3 and lever 5 are adopted in practical applications
With shell half-and-half by buckle or screw splicing, wherein swivel head 3 is by the first rotation casing 31 and the second rotation casing
32 synthesis, lever 5 are synthesized by the first lever shell 51 and the second lever shell 32, the first rotation casing 31 and the second swivel head
The cover of shell 32 is outside the hinged place of lever 5, wherein passes through shaft between the second rotation casing 32 and the second lever shell 52
521 is freely hinged, and shaft 521 can form on the outside cylindrical projection and the second rotation with 52 integrated injection molding of the second lever shell
Rotary head shell 32 is hinged, then forms shaft boss close to 52 inside of the second lever shell, which is provided with the bullet for retaining spring 8
Spring location hole 522.Swivel head mounting hole 311 and lever is respectively set on the first rotation casing 31 and the first lever shell 51
Mounting hole 511, the first rotation casing 31 and the second lever shell 51 pass through swivel head mounting hole 311 and lever mounting hole 511
It is sleeved on adjusting knob 4, is respectively equipped with the first positioning groove 312 in the inner wall of swivel head mounting hole 311 and lever mounting hole 511
It is chimeric with positioning convex platform with the second positioning groove 512.
Adjusting knob 4 is a cylindrical body, and one end is equipped with adjusting knob location hole 401, and adjusting knob 4 passes through adjusting knob location hole
401 are sleeved on the shaft boss of shaft 521, and the both ends of spring 8 are respectively positioned at adjusting knob location hole 401 and location hole of the spring
In 522, adjusting knob 4, which compresses spring 8, to be arranged, and passes through the axial limit of compressed spring between adjusting knob 4 and the first lever shell 51
Position shaft shoulder limit.4 other end of adjusting knob stretches out the first rotation casing 31 and is arranged, by pressing inward against adjusting knob 4, it can be achieved that fixed
Position boss 402 is separated along axial slide onto of the second positioning groove 512 with the first positioning groove 312, and swivel head 3 opposite can be held at this time
Handle 5, which is freely rotated, realizes punch tip angular adjustment, after having adjusted, unclamps adjusting knob 4, will adjust under the elastic force effect of spring 8
4 return of button is saved, keeps positioning convex platform 402 same with the first positioning groove 312 after the second positioning groove 512 and adjustment angle simultaneously
When it is chimeric, locking adjusts the swivel head 3 and lever 5 after angle.
