Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without making creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution:

the utility model provides a gear bores oilhole location frock, which comprises a base 1, be provided with curb plate 2 on the base 1, be provided with backing plate 3 on the curb plate 2, be provided with fixed axle 4 on the backing plate 3, convex key 5 has on the fixed axle 4, the outside of fixed axle 4 is provided with holding ring 6, the inner wall of holding ring 6 has the keyway 12 with convex key 5 adaptation, sliding fit through keyway 12 and convex key 5 makes holding ring 6 slide on fixed axle 4, and prevent that holding ring 6 from taking place to rotate, spout 13 has on the holding ring 6, sliding connection has slider 7 in the spout 13, be provided with the adjustment mechanism of the removal of control holding ring 6 on the fixed axle 4, a control ring 6 controls.
