Deng.
In an embodiment of the present invention, 11 limit holes 1112 can be set, the first blend stop 1311 and the second blend stop 1313 it
Between angle be 100 °.After spacing ball 15 is moved to another adjacent limit hole 1112 by a wherein limit hole 1112, head group
The angle A that part 30 rotates is 10 degree.
It should be understood that the spacing of the quantity and adjacent limit hole 1112 of limit hole 1112 can be set according to actual needs,
It adjusts after spacing ball 15 is moved to another adjacent limit hole 1112 by a wherein limit hole 1112, what nose assembly 30 rotated
Angle.
The limit hole 1112 of technical solution of the present invention is distributed in center of rotation axis and the first side wall with the shaft 13
The intersection point of 111 place planes is the center of circle, with the distance between the intersection point and the spacing ball 15 on the circumference of radius so that
Spacing between spacing ball 15 and any limit hole 1112 is equal so that nose assembly 30 under the drive of tilting component 10 in
During vertical direction turns to a preset pitch angle, spacing ball 15 can be limited in any limit hole 1112.
The spacing ball 15 of technical solution of the present invention is contained in holding tank 1321, drive of the nose assembly 30 in tilting component 10
Under during vertical direction turns to a preset pitch angle, which can roll along the first side wall 111, and limit
Positioned at the hole wall of corresponding limit hole 1112.When spacing ball 15 is limited in the hole wall of corresponding limit hole 1112, head can be made
Component 30 is maintained at the pitch angle without gliding.By the cooperation between spacing ball 15 and limit hole 1112, user adjusts limit
Nose assembly 30 can be moved to suitable pitch angle by the position of position ball 15.
The tilting component 10 further includes the elastic component 17 for being contained in holding tank 1321, and one end of the elastic component 17, which abuts, to be accommodated
The bottom wall of slot 1321, the other end abut spacing ball 15.
Elastic component 17 can be spring.
Spacing ball 15 is movably arranged at by elastic component 17 in holding tank 1321, and the bottom wall of holding tank 1321 and are passed through
The restriction effect of one side wall 111 to elastic component 17 to apply a fixed pretightning force, and elastic component 17 is in long compression shape at this time
State.When nose assembly 30 is faced upward or when nutation, spacing ball 15 is moved to another limit from a limit hole 1112 in vertical direction
In the hole 1112 of position, in the process, elastic component 17 further compression and then again slow release first, always due to elastic component 17
In long compressive state, therefore after spacing ball 15 is moved to another limit hole 1112, elastic component 17 applies spacing ball 15
One elastic force is against with being stopped on the hole wall of limit hole 1112, and nose assembly 30 can be made to be maintained at a pitch angle without under
It is sliding.
Join Fig. 6 a, 1315 the first blend stop of backstop 1311 of limited post, at this point, elastic ball 15 is limited in close to 11 edge of holder
Limit hole 1112, at this point, tilting component 10 is in initial position 1117 (final position of bowing on that is), the pitching of tilting component 10
Angle is 90 °, and nose assembly 30 is blown towards day.At this point, torsional spring 135 has been in compressive state.
Join Fig. 6 b, rotating shaft 13, after being moved close to the direction of limited post 1315, elastic ball 15 limits the second blend stop 1313
Positioned at the limit hole 1112 positioned at intermediate region, tilting component 10 is in pitch position, and the pitch angle of tilting component 10 is
Less than 90 °, it is more than -10 °.At this point, torsional spring 135 is also in compressive state, and the radius of torsional spring 135 respectively enclosed is less than in initial
The radius of torsional spring 135 when position 1117 respectively enclosed.
Join Fig. 6 c, is rotated further shaft 13, the second blend stop 1313 is moved along close to the direction of limited post 1315, and elastic ball
15 are limited in the limit hole 1112 close to 11 other edge of holder positioned at one, and tilting component 10, which is in down, faces upward final position, pitching
The pitch angle of component 10 is -10 °.At this point, torsional spring 135 is also in compressive state, and the radius of torsional spring 135 respectively enclosed is less than place
The radius of torsional spring 135 when pitch position 1117 respectively enclosed.
The shaft 13 further includes connecting second end 133 with the first end 131, and the cross-sectional area of the shaft 13 is along from first end
131 successively decrease to the direction of second end 133.
Successively decrease from first end 131 to the direction of second end 133 on the cross-sectional area edge of the shaft 13 so that torsional spring 135 can jail
Admittedly be sheathed in shaft 13, and torsional spring 135 between one end and shaft of limit hole 1112 and spacing ball 15 13 have compared with
Good switching performance.
The tilting component 10 further includes a gear line muscle 1315, and one end of the gear line muscle 1315 connects with the first blend stop 1311

In an embodiment of the present invention, which further bends, to form bending segment 1115.The bending segment
1115 can protect user during installing spacing ball 15, not be scratched.
By spacing ball 15 by the guiding on inclined-plane 1114, after installation to holding tank 1321, rotatable shaft 13, so that limit
Ball 15 is limited in the hole wall of a limit hole 1112.It defines spacing ball 15 and is limited in the limit hole 1112 near holding tank 1321
The position of hole wall is initial position 1117, is rotated further shaft 13, so that spacing ball 15 leaves from the initial position 1117, and after
The continuous hole wall for being limited in other limit holes 1112, to keep nose assembly 30 that there is preferable stability in pitching movement.
It should be understood that elastic component 17 also under the guiding on inclined-plane 1114, is rolled along inclined-plane 1114 to be contained in holding tank
In 1321.
The nose assembly 30 of the present invention turns to a preset pitch angle under the drive of tilting component 10 in vertical direction
When spending, which is limited in the hole wall of corresponding limit hole 1112, so that nose assembly 30 can be in the preset pitch angle
Degree keeps stablizing.Since the second end 1113 of holder 11 is bent relative to first end 1111 to form inclined-plane 1114, holder 11
Second end 1113 and the gap of the end face of shaft 13 become larger so that when spacing ball 15 is installed on holding tank 1321, spacing ball 15
It can be rolled along inclined-plane 1114 to be contained in holding tank 1321 so that nose assembly of the invention under the guiding on inclined-plane 1114
30 have the advantages that simple installation.
Join Fig. 7-10, the present invention also provides a kind of head section mechanisms 100, including nose assembly 30 and runner assembly 50, also wrap
Include the tilting component 10, the nose assembly 30 is connect with tilting component 10, the tilting component 10 drive nose assembly 30 in
Vertical direction turns to preset pitch angle；The runner assembly 50 connect with tilting component 10 and positioned at tilting component 10
Lower section, the runner assembly 50 drive nose assembly 30 to be rotated in horizontal direction.
Since the head section mechanism 100 uses whole technical solutions of above-mentioned all embodiments, at least have above-mentioned
All advantageous effects caused by the technical solution of embodiment, this is no longer going to repeat them.
In an embodiment of the present invention, the both ends of shaft 13 are convexly equipped with protruding end (not indicating), which can be with phase
The connection wall 311 answered connects.The both ends of shaft 13 are connected with corresponding connection wall 311 respectively so that, can band when shaft 13 rotates
Dynamic connection wall 311 rotates, so that nose assembly 30 can rotate under the drive of tilting component 10.
It should be understood that pitch orientation shown in Fig. 7 be nose assembly 30 in the direction that vertical direction rotates.
In an embodiment of the present invention, the pitch angle is ranging from：- 30 °~70 °, -30 °~80 °, -30 °~90 °, -
30 °~120 °, -30 °~110 °, -30 °~100 °, -20 °~80 °, -20 °~90 °, -20 °~100 °, -20 °~110 °, -
