Provided with helical tooth, the worm shaft is provided with a through hole, is provided with two locating rods in the through hole, two locating rods it
Between be provided with spring；One end of the worm shaft is provided with the columned installation portion of hexagon；The worm gear includes worm wheel body, the snail
Wheel body periphery is provided with worm-gear toothing, and the inner side of the worm wheel body is provided with through hole, and the through hole is into regular hexagon；The side of the through hole
Periphery is provided with the projection of regular hexagon corresponding with the through hole, and the projection is provided with least one connecting hole.
Further, the groove of annular is additionally provided between the through hole and the installation portion.
As preferable technical scheme, the depth of the groove is more than or equal to the 1/5 of the worm screw shaft diameter and is less than
The 1/3 of the worm screw shaft diameter.
As further preferred technical scheme, the cross section of the groove is in the arc-shaped.
In addition, the helical tooth includes initiating terminal, pars intermedia and terminal, the helical tooth at the terminal and initiating terminal
Thickness is more than the 2/5 of the pars intermedia helical tooth thickness.
As preferable technical scheme, the quantity of the connecting hole is two, and using the center of through hole as symmetrical point symmetry
Set.
The utility model is relative to the beneficial effect of prior art：The worm screw is led to by setting through hole on worm shaft
The locating rod with spring is provided with hole, locating rod need to be only pressed during assembling and then worm screw is inserted into power set, locating rod is just
It can be got up by spring supporting, realize being fixedly connected for worm screw and power set, so can be by worm screw and power set jail
Jail links together, and assembles simple；In addition, by the way that the terminal on worm screw and the helical tooth thickness at initiating terminal are set
Be set to 2/5 more than pars intermedia helical tooth thickness, because thickness is big, so intensity is all right, such worm screw during work,
The phenomenon being broken would not occur, can effectively improve the service life of worm screw；Worm gear is connected using the through hole of hexagon
Output shaft is connect, such long-term use is not in because the phenomenon skidded occurs in abrasion, and is to set through hole to enter furthermore with projection
Row is longitudinally fixed, and effect is more preferable.

Fig. 1 is overall structure figure of the present utility model；
Fig. 2 is worm structure figure of the present utility model；
Fig. 3 is positional lever structure figure of the present utility model；
Fig. 4 is worm gear arrangement figure of the present utility model.
Embodiment
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings.Herein it should be noted that
It is used to help understand the utility model for the explanation of these embodiments, but does not form to restriction of the present utility model.This
Outside, as long as technical characteristic involved in each embodiment of the utility model disclosed below does not form conflict each other
Can is mutually combined.
As Figure 1-3, a kind of follow-on worm gearing, including worm screw 1 and the worm gear that is engaged with
2, wherein, worm screw 1 includes worm shaft 101, and 101 sides of worm shaft are provided with helical tooth 102, and worm shaft 101 is provided with one and led to
Hole 103, through hole 103 is interior to be provided with two locating rods 104, and spring 105 is provided between two locating rods 104；One end of worm shaft 101
Provided with the columned installation portion 106 of hexagon.Locating rod 104 need to be only pressed during assembling and then worm screw is inserted into power set, it is fixed
The position can of bar 104 is supported by spring 105, realizes being fixedly connected for worm screw and power set, so can be by worm screw
