Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Please refer to Fig. 1-4, a kind of cement lifting device output shaft with defencive function, including output shaft 1, output shaft
1 is driven by motor, and output shaft 1 is clamped by card ball 6 and card slot 12 and driving wheel 11, and driving wheel 11 is driven to rotate together,
The outside of output shaft 1 offers loose slot compatible with hinge bar 5 and the outside of output shaft 1 is offered with diameter not less than card
The loose slot of 6 diameter of ball, there are four the quantity of loose slot, and the outside of output shaft 1 is opened up there are four equally distributed sliding slot 2, bullet
Spring 1 can be compressed and be extended in sliding slot 2, and the shape of sliding slot 2 is the size of arc and sliding slot 2 not less than spring 1
Size, spring 1 are that the quantity of compressed spring and spring 1 is four, and the middle part of sliding slot 2 is plugged with spring 1, spring 1
Outside be fixedly connected with sliding block 4, sliding block 4 can move under the action of spring 1, and the quantity of sliding block 4 is eight and sliding block 4
Material be steel material, the material of the quantity of hinge bar 5 eight and hinge bar 5 is alloy material, the hardness of hinge bar 5 compared with
Height, the outside of sliding block 4 are rotatably connected to hinge bar 5, and hinge bar 5 drives card ball 6 mobile, make card ball 6 withdraw in output shaft 1 or
It is popped up out of output shaft 1.
The outside of hinge bar 5 is rotatably connected to the card ball 6 with the outside grafting of output shaft 1, and the material of card ball 6 is copper and iron conjunction
The golden material and coefficient of friction on 6 surface of card ball is lower, spring 27 are that the quantity of compressed spring and spring 27 is four, card ball 6
Inside be fixedly connected with the spring 27 being fixedly connected with the inner wall of output shaft 1, spring 27 plays the work for popping up card ball 6
