Specific embodiment
The present invention will be described in further detail with reference to the accompanying drawing:
A kind of tool of auxiliary propeller installation, including pull rod 4, briquetting 8, three arm supports 2, screw rod 7 and handle 1；
Three arm support 2 processing is provided with one 2A of groove on each support arm 3, for installing pull rod there are three support arm 3
4, a through-hole one is processed perpendicular to one 2A of groove on support arm 3, straight pin is passed through into through-hole one, support arm 3 and pull rod 4 is fixed
Connection；The position of three support arms 3 of three arm supports 2 being connected is machined with internal thread hole, for installing screw rod 7；
One end of the pull rod 4 can be embedded in the U-type groove 2A of three arm supports 2, and the other end of pull rod 4 is machined with boss,
The intermediate of boss processes two 2B of groove, and nut is placed on two 2B of groove；
7 head of screw rod is machined with through-hole two, to install handle 1；There is one section of external screw thread in the middle part of screw rod 7, be used for
With the screw-internal thread fit of three arm supports 2；There is another section of external screw thread in the tail portion of screw rod 7；
The briquetting 8 is sequentially coaxially connected by cylindrical body one, cylindrical body two and is formed, and the diameter of cylindrical body one is less than cylindrical body
Two diameter is successively machined with coaxial threaded hole and blind hole along axial direction at the center in cylindrical member at one end face, and diameter of blind hole is big
In the diameter of threaded hole；Blind hole is machined with along axial direction at the center of cylindrical body biend；
The threaded hole of cylindrical body one and the external screw thread of screw rod 7 match, and 7 tail portion external screw thread of screw rod is screwed into the blind of cylindrical body one
Kong Zhong；Screw rod 7 can rotate freely after installing；
The blind hole of cylindrical body biend is connected with the head of propeller.
