a rotating handle is arranged at the upper part of the lifting sleeve;

the draw hook assembly comprises a draw pin hook and a draw hook seat sleeved on the outer surface of the middle part of the draw pin hook;

the pull pin hook is fixedly connected with the pull hook seat;

the lower part of the pin hook is provided with a barb-shaped drag hook matched with the barb groove of the pin;

the outer surface of the draw hook seat and the inner surface of the lifting sleeve are both provided with thread structures and are matched, and the draw hook seat and the lifting sleeve are connected through the thread structures.

Furthermore, the rotating handle is two deflector rods arranged on the outer surface of the opposite side of the upper end of the lifting sleeve.

Further, the draw hook seat lateral wall sets up the screw hole, the tight screw fixed connection in the top of screw hole is passed through to broach hook and draw hook seat.

Further, the outer diameter of the upper portion of the draw hook seat is larger than that of the lower portion of the draw hook seat, and a thread structure used for being in threaded connection with the lifting sleeve is arranged on the outer surface of the upper portion of the draw hook seat.

Furthermore, the pull pin hook and the pull hook seat are of an integrated structure.

The utility model has the advantages that:

1. the utility model discloses pin remove device can guarantee that the pin keeps vertical upwards when withdrawing from, does not harm the pressure disk pinhole.

2. The utility model discloses pin remove device's easy operation, it is controllable to take out the process, has avoided the pressure disk damage, has effectively reduced the product disability rate.

3. The utility model discloses pin remove device design has barb form drag hook, and the fixture seat is placed on clutch case assembly, borrows clutch case assembly body and takes out the pin as supporting the impetus point, and remove device easy operation and efficient.

4. The utility model discloses pin remove device is provided with twist grip, labour saving and time saving, convenient and high-efficient.

Detailed Description

As shown in figure 1, the utility model relates to a pin remove device, including lifting unit and drag hook subassembly.

The lifting assembly comprises a lifting sleeve 1, a rolling bearing 7 and a fixture seat 4 arranged at the lower end of the lifting sleeve; the upper end of the inner side of the fixture seat 4 is provided with an annular step gap, and the rolling bearing 7 is arranged in the annular step gap; the lifting sleeve 1 is connected with the fixture seat 4 through a rolling bearing 7, the outer surface of the lower end of the lifting sleeve 1 is in contact with the inner surface of the upper end of the annular step notch of the fixture seat 4, and the rolling bearing 7 can drive the lifting sleeve 1 to rotate.

The drag hook component comprises a drag hook 2 and a drag hook seat 3 which is sleeved on the outer surface of the middle part of the drag hook 2. The pull pin hook 2 is fixedly connected with the pull hook seat 3. In this embodiment, 3 lateral walls of drag hook seat set up screw hole 9, and the blind pin hook 2 is connected through the tight screw fixed connection in the top that sets up in screw hole 9 with drag hook seat 3, and other embodiments also can set up blind pin hook 2 and drag hook seat 3 structure as an organic whole. The lower part of the pin hook 2 is provided with a barb-shaped drag hook matched with the barb groove of the pin 6. The surface of the draw hook seat 3 and the inner surface of the lifting sleeve 1 are both provided with thread structures and are matched, and the draw hook seat 3 and the lifting sleeve 1 are connected through the thread structures. The upper portion external diameter of draw hook seat 3 is greater than the external diameter of lower part, and the upper portion surface is provided with the helicitic texture that is used for carrying out threaded connection with lifting sleeve 1.
