Sliding amplitude of the T-shaped boss in T-slot is limited, sideslip is avoided, screwdriver bit can be made to be easier to find the center of screw,
Convenient for tightening.
Further, specifically, being also provided with lower radially installed through-hole along lower sleeve radial direction in the T-shaped boss.
Further, lead to specifically, offering upper radially installed along square radial direction on T-slot on the upper bush
Hole, the center line of the length direction of the central axis and T-slot of upper radially installed through-hole is in the same plane.
The utility model has the beneficial effects that the T-slot shaft coupling of the utility model, by shaft coupling fission be upper bush and
Lower sleeve can move between upper bush and lower sleeve, so that screwdriver bit finds the center of screw, by the way that kidney-shaped is arranged
Hole can limit sliding amplitude of the T-shaped boss in T-slot, and movement is avoided excessively screwdriver bit can be made to be easier to find
The center of screw, convenient for tightening.

Specific embodiment
The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram,
Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows composition related with the utility model.
It as shown in Figs. 1-5, is the utility model optimum embodiment, a kind of T-slot shaft coupling, including upper bush 1 and trap
Cylinder 2, the center of upper bush 1 offer installation through-hole 11, and the center of lower sleeve 2 offers lower installation through-hole 21, and upper installation is logical
Hole 11 and the coaxial arrangement of lower installation through-hole 21, the internal diameter of upper installation through-hole 11 are greater than the internal diameter of lower installation through-hole 21, under upper bush 1
T-slot 12 is radially offered on end face, radially evagination there are T-shaped boss 22 for the upper surface of lower sleeve 2, and lower installation through-hole 21 passes through
T-shaped boss 22 are worn, T-shaped boss 22 and T-slot 12 are slidably matched, so that the shape after upper bush 1 and 2 grafting of lower sleeve combination is in
It is cylindric, T-shaped boss sliding limitation structure is additionally provided on T-slot shaft coupling.
T-shaped boss sliding limitation structure includes two gag lever posts 3 for being symmetricly set on 22 two sides of T-shaped boss, under upper bush 1
Two sides on end face positioned at T-slot 12 are symmetrically arranged with upper limit hole 13, and the upper surface of lower sleeve 2 is located at the two of T-shaped boss 22
Side is symmetrically arranged with kidney slot 23, and the upper end of gag lever post 3 is mounted in corresponding upper limit hole 13, and the lower end of gag lever post 3 penetrates
