Further, the hexagonal rod coordinates with hexagonal set for slide fit.
The utility model has the advantages that:
When ripple pearl set down compresses the second spring, expose ripple pearl hole, for installing ripple pearl, ripple pearl set resets, ripple
Pearl, which is stuck in ripple pearl hole, to be difficult to drop out, and when crosspoint tip screwdriver head inserts end-face hole, ripple pearl blocks crosspoint tip screwdriver head so that crosspoint tip screwdriver head is complete
Fix entirely;The novel lock screw transmission mechanism employs the first candan universal joint and the second candan universal joint, it is possible to achieve
Hole and the transmission of output shaft decentraction are processed, it is achieved thereby that the multiposition on small-size product is processed simultaneously, production is improved
Efficiency.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the accompanying drawing used required in description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
It is some embodiments of the present utility model, for those of ordinary skill in the art, is not paying the premise of creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
The structural representation for the novel lock screw transmission mechanism that Fig. 1 provides for the utility model embodiment;
The exploded view for the novel lock screw transmission mechanism that Fig. 2 provides for the utility model embodiment.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the premise of creative work
Lower obtained all other embodiment, belongs to the scope of the utility model protection.
Such as Fig. 1 and Fig. 2, the utility model embodiment provides a kind of novel lock screw transmission mechanism, including buckle head 1, institute
Buckle head 1 is stated to be installed on electric screwdriver.Or, the buckle head 1 is installed on some other rotatable output shaft, Ke Yigen
Selected according to demand.
Such as Fig. 1 and Fig. 2, the buckle head 1 is connected with the first candan universal joint 2, first candan universal joint 2 and 1
Angle rod 4 is connected, and the hexagonal rod 4 is connected with the second candan universal joint, and hexagonal set 3 and the first bullet are arranged with the hexagonal rod 4
Spring 5, the cross section of the hexagonal rod 4 is hexahedron, and it has six angles, and the hexagonal set 3 is endoporus hexagonal, is sheathed on described
The outside of hexagonal rod 4.Wherein, the hexagonal rod 4 is that slide fit coordinates with hexagonal set 3.First candan universal joint 2 can make
The rotation in certain angle of the hexagonal rod 4.
Such as Fig. 1 and Fig. 2, the two ends of the first spring 5 abut the hexagonal set 3 and second candan universal joint 6 respectively,
First spring 5 plays a part of buffering.
Such as Fig. 1 and Fig. 2, second candan universal joint 6 connects one end of an axis of guide 7, the other end of the axis of guide 7
Provided with stage portion 8, the external diameter of the stage portion 8 is less than the external diameter of the axis of guide 7, in this preferred embodiment, the step
Portion 8 is integrally formed with the axis of guide 7 so that its overall processing is more convenient.Second candan universal joint 6 can cause institute
State the axis of guide 7 to rotate in certain angle, the cooperation pilot hole slide fit of the axis of guide 7 and lock screws apptss coordinates.
Such as Fig. 1 and Fig. 2, the end face of the stage portion 8 is provided with the mounting hole for being used for installing crosspoint tip screwdriver head 12, the stage portion
8 side is provided with the bead hole 11 for being used for installing bead, and the mounting hole connects setting, the step with the bead hole 11
Second spring 9 and bead set 10 are arranged with portion 8, the bead set 10 is sheathed on the outside of bead hole 11, second bullet
The two ends of spring 9 are connected with bead set 10 and the axis of guide 7 respectively.When ripple pearl set down compresses the second spring 9, dew
Go out ripple pearl hole, for installing ripple pearl, ripple pearl set is resetted, and ripple pearl, which is stuck in ripple pearl hole, to be difficult to drop out, when the insertion end of crosspoint tip screwdriver head 12
Face, ripple pearl blocks crosspoint tip screwdriver head 12 so that crosspoint tip screwdriver head 12 is completely fixed.
The utility model can effectively fix crosspoint tip screwdriver head by setting bead to cover the structure of 10 and second spring 9
12, fixed form is installed simple, firm.The novel lock screw transmission mechanism employs the first candan universal joint 2 and the 20th
Word universal joint 6, it is possible to achieve processing hole and the transmission of output shaft decentraction, it is achieved thereby that the multiposition on small-size product is same
Shi Jiagong, improves production efficiency.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
