In order to achieve the purpose, the invention provides an integral shaft fork for EPS, which comprises a first cylinder body, a second cylinder body, fixing lugs and protruding strips, wherein the top of the first cylinder body is fixedly provided with two fixing lugs which are symmetrically distributed, the fixing lugs are provided with lug holes, the two lug holes are positioned on the same axis, the bottom of the first cylinder body is fixedly provided with the second cylinder body, the side wall of the second cylinder body is provided with a plurality of protruding strips, the direction of the protruding strips is the same as that of the second cylinder body, and the first cylinder body, the second cylinder body, the fixing lugs and the protruding strips are of an integral structure.
Preferably, the diameter of the second cylinder is smaller than that of the first cylinder, a transition table is arranged between the first cylinder and the second cylinder, and the transition table is in an inverted cone frustum shape.
Preferably, the cross section of the convex strip is in an isosceles trapezoid shape, and the cross section of the second column body is in a gear shape.
Preferably, the upper end surface of the fixing lug is an arc surface concentric with the lug hole.
Preferably, the side edges of the fixing lugs facing away from each other are chamfered.
Preferably, the upper end of the first column body and the two fixing lugs form a U-shaped structure, and a fillet is arranged at the joint of the fixing lugs and the first column body.
Preferably, the bottom edge of the second column body is provided with a rounded corner.
The invention has the beneficial effects that: according to the invention, the first cylinder, the second cylinder, the fixing lug and the convex strip are made into an integrated structure, so that the shaft fork structure is simpler, firmer and convenient to process; the arrangement of the convex strips enables the shaft fork to be conveniently fixed with other parts and to be firmly fixed; the transition table enables the connection between the first column body and the second column body to be firmer.
