For realizing above-mentioned purpose, the technical solution of the utility model is: a kind of with gearshift location and spacing flexible axle manipulator, comprise operating rod bearing; The lower end of operating rod bearing is provided with bearing, and the intermediate vertical of operating rod bearing offers mounting hole, and positioning means is installed in the mounting hole; Said positioning means is by holddown spring, steel ball and tighten plug screw and constitute; The bottom of positioning means is provided with steel ball, and the top of steel ball is provided with holddown spring, and the upper end of holddown spring is equipped with tightens plug screw; Offer intermediate groove corresponding to steel ball on the arc surface of said bearing, the both sides of intermediate groove offer the side groove respectively.
The cross section of said intermediate groove and side groove is trapezoidal, and the width of side groove cross section is grown 1 millimeter-10 millimeters than the width of intermediate groove cross section.
Notch outer rim between said intermediate groove and the side groove is set to fillet.
Said intermediate groove and side groove are along being set on the sidewall of normal direction and the corresponding cambered surface of steel ball.
The bottom land of said intermediate groove and side groove is set to cambered surface, and its cambered surface center of circle is on the axle center of bearing.
The beneficial effect of the utility model is:
1. the utility model offers mounting hole on operating rod bearing; Be equipped with by holddown spring, steel ball in the mounting hole and tighten the positioning means that plug screw constitutes; Steel ball can be level and smooth under the effect of holddown spring entering bearing arc surface on intermediate groove or side groove in, with the gearshift location of realizing the flexible axle manipulator and spacing.
2. the utility model is simple in structure, and part processing is easy, and is easy to use, and wearing and tearing backs is changed easily, and the switching of flexible axle manipulator on different gears is smooth and easy, and the location that can realize shifting gears and spacing, and Applicable scope is extensive.

Embodiment
Below in conjunction with description of drawings and embodiment the utility model is done further to describe in detail.
Referring to Fig. 3, Fig. 4, a kind of of the utility model locatees and spacing flexible axle manipulator with gearshift, comprises operating rod bearing 5; The lower end of operating rod bearing 5 is provided with bearing 4; The centre of operating rod bearing 5 is equipped with positioning means, and said positioning means is by holddown spring 2, steel ball 3 and tighten plug screw 1 and constitute, and the bottom of positioning means is provided with steel ball 3; The top of steel ball 3 is provided with holddown spring 2; The upper end of holddown spring 2 is equipped with tightens plug screw 1, offers intermediate groove 7 corresponding to steel ball 3 on the arc surface of said bearing 4, and the both sides of intermediate groove 7 offer side groove 8 respectively.
The cross section of said intermediate groove 7 and side groove 8 is trapezoidal, and the width of side groove 8 cross sections is grown 1 millimeter-10 millimeters than the width of intermediate groove 7 cross sections.
Notch outer rim between said intermediate groove 7 and the side groove 8 is set to fillet.
Said intermediate groove 7 and side groove 8 are along being set on the sidewall of normal direction and steel ball 3 corresponding cambered surfaces.
The bottom land of said intermediate groove 7 and side groove 8 is set to cambered surface, and its cambered surface center of circle is on the axle center of bearing 4.
The intermediate vertical of operating rod bearing 5 offers mounting hole, and positioning means is installed in the mounting hole, and positioning means faces the bearing 4 that is positioned at the below, and positioning means is by holddown spring 2, steel ball 3 and tighten plug screw 1 and constitute.The bottom of positioning means is provided with steel ball 3; The top of steel ball 3 is provided with holddown spring 2, and the upper end of holddown spring 2 is equipped with tightens plug screw 1, offers internal thread on the upper end inwall of mounting hole; Tighten plug screw 1 and fix, holddown spring 2 is compressed through tightening plug screw 1 through this internal thread.
