[0008] Further limit, one end of the crankshaft is sequentially penetrated by combination oil seal, oil seal seat and machine body from left to right, and the oil seal seat is fixedly installed on the machine body.

[0009] Further limit, three waist-shaped holes are arranged on the positioning seat, and the sliding block is installed on the positioning seat by screw and the waist-shaped hole.

[0010] Further limited, the positioning seat is in the form of a boss, a through interface is provided at the center of the positioning seat, the through interface and the center hole of the crankshaft are on the same horizontal line, and the mounting bolt penetrates through the positioning seat through the through interface and is fixedly installed on the positioning seat.

[0011] The beneficial effects of the utility model relative to the present stage technology are:

[0012] 1. The positioning seat is clamped on the crankshaft through the fixed block and the sliding block and is located in the mounting groove on one side of the crankshaft, the positioning seat is rotated through the mounting bolt, and the oil seal is pulled out, so that the dismounting quality of the oil seal is ensured, and relevant parts are prevented from being damaged.

[0013] 2. Three waist-shaped holes are arranged on the positioning seat, the position of the sliding block on the positioning block is adjusted to a certain extent, and thus the position of the oil seal groove on one side of the crankshaft is adjusted. BRIEF DESCRIPTION OF DRAWINGS
