[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) During installation, the operator places the bottom of the transfer case body on the top of the mounting seat, and inserts the insert block and the positioning block into the insert tube and the positioning groove respectively. Then, the operator starts the drive motor to drive the worm to rotate along the positioning strip. When the worm rotates, the rotating rod is driven to rotate through the worm gear. When the rotating rod rotates, the two first bevel gears are driven to rotate along the two rotating shafts. When the two first bevel gears rotate, the two first gears are driven to rotate along the two rotating frames through the two second bevel gears. When the two first gears rotate, they will drive the gear column to move downward;

[0015] When the tooth column moves downward, it drives the insert cylinder downward, and when the insert cylinder moves, it drives the four first slide bars to slide along the inside of the four first slide grooves, thereby increasing the stability of the insert cylinder when it moves.

When the two moving rods move toward each other, they will drive the two limit heads to be stuck in the inside of the two limit grooves, so that when the insert cylinder continues to move downward, the two limit heads can pull the insert block downward, and when the insert block moves downward, the pad will tighten the top of the mounting seat, thereby performing limited installation;

[0016] (2) When the insertion tube moves downward, the two moving blocks are pulled toward each other through the two transmission rods. When the two moving blocks move, they both drive the third slide bar to slide along the inside of the third slide groove, thereby increasing the stability of the two moving blocks when they move. When the two moving blocks move toward each other, they drive the two clamping rods to be clamped into the inside of the two clamping grooves for limited installation, thereby improving the stability of the installation;

[0017] (3) When the insertion tube moves downward, the two vertical rods will be driven downward through the two support rods. When the vertical rods move, they will drive the second slide bar to slide along the inside of the second slide groove, which increases the stability of the vertical rod when it moves. When the two vertical rods move downward, the two second gears will be driven to rotate along the two positioning seats through the two racks. When the two second gears rotate, the two shaft rods will be driven to rotate inside the two shaft sleeves. When the two shaft rods rotate, the two insertion rods will be driven to move toward each other through the threaded rods. When the two insertion rods move, the sliding sleeves will be driven to slide along the surface of the sliding rods, which increases the stability of the insertion rods when they move. When the two insertion rods move toward each other, they will be inserted into the inside of the two slots for limit, thereby further improving the stability of the limit installation.

[0018] (4) The transfer case is easy to install and has strong installation stability, thereby reducing the workload of operators and improving efficiency, and the limit will not loosen in a moving and vibrating environment. BRIEF DESCRIPTION OF THE DRAWINGS
