Tip at, the other end is against on guide block installing rack；Between described middle mountain guide block and needle overturning guide block, there is a lever, lever rotation
Being arranged in the second rotary shaft, the second rotary shaft is fixed on guide block installing rack；Described middle mountain guide block and needle overturning guide block are towards thick stick
The side of bar is equipped with groove, and lever two ends are respectively placed in the groove of middle mountain guide block and needle overturning guide block.
During utility model works, driven by motor cam rotation, on projection outline, each point is different to the distance of motor shaft,
When the convex place of cam rotation to outline, power upwards of middle Rhizoma Atractylodis Macrocephalae bar right-hand member (one end inconsistent with cam) can be given,
Make middle Rhizoma Atractylodis Macrocephalae bar left end push down on middle mountain guide block so that middle mountain guide block is released downwards, enter duty；Meanwhile, middle mountain
Guide block drives one end of lever to move down, then the lever other end drives and moves on needle overturning guide block, state of deactivating.When outside cam rotation
During the recess of profile, the spring at needle overturning guide block tip is to one downward power of needle overturning guide block so that needle overturning guide block is released downwards,
Enter duty, lever drives is moved on the guide block of mountain, state of deactivating simultaneously.This utility model utilizes cam in conjunction with thick stick
Rod principle control in the elevating movement of mountain guide block, it is achieved the work switching of middle mountain guide block and needle overturning guide block, it is ensured that same
Time, that a kind of guide block the most in need was in operating position, met braiding demand.
Accompanying drawing explanation
It is described in further detail below in conjunction with accompanying drawing and embodiment of the present utility model
Fig. 1 is structural representation of the present utility model；
Fig. 2 is side sectional view of the present utility model.
Figure is labeled as: connecting rod base 1, motor 2, middle Rhizoma Atractylodis Macrocephalae bar 3, pole 31, guide block installing rack 4, middle mountain guide block 5, needle overturning
Guide block 6, cam the 7, first rotary shaft 8, bearing 9, spring 10, lever the 11, second rotary shaft 12.
Detailed description of the invention
See accompanying drawing.The present embodiment includes connecting rod base 1, motor 2, middle Rhizoma Atractylodis Macrocephalae bar 3, guide block installing rack 4, middle mountain guide block 5 and
Needle overturning guide block 6；Described motor 2 is arranged on connecting rod base 4, and motor shaft is installed a cam 7；Install in the middle of described middle Rhizoma Atractylodis Macrocephalae bar 3
