[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-5 As shown, a broach guide sleeve includes a guide sleeve body 1. The outer surface of the guide sleeve body 1 is slidably connected to a fixing frame 2. A plurality of fixing bolts 3 are installed inside the fixing frame 2. The fixing frame 2 is connected to the connecting workpiece above the outer guide sleeve body 1 through the fixing bolts 3. It can play an auxiliary connection role between the guide sleeve body 1 and the connecting workpiece, and there is no need to change the internal structure of the connecting workpiece, which is convenient for installation.

[0023] A fixing plate 4 is fixedly installed on the lower surface of the fixing frame 2. There are multiple groups of fixing plates 4 and they are arranged in an array on the lower surface of the fixing frame 2. A fixing hole 5 is opened inside the fixing plate 4. A limiting groove 6 is opened inside the fixing plate 4. A clamping plate 7 is slidably connected to the inside of the fixing hole 5. The position of the clamping plate 7 corresponds to the fixing hole 5 one by one. When the guide sleeve body 1 is connected, the clamping plate 7 will enter the inside of the fixing hole 5, and the outside of the guide sleeve body 1 can be fixed by the clamping plate 7.

[0024] A control board 8 is fixedly installed on one side of the card plate 7, and the movement of the card plate 7 can be controlled by the control board 8. A fixing box 12 is fixedly installed on the outer surface of the guide sleeve body 1, and a limiting rod 13 is fixedly installed on the inner wall of the fixing box 12. The outer surface of the limiting rod 13 is slidably connected to the inside of the control board 8 and the card plate 7. The control board 8 and the card plate 7 can be limited by the limiting rod 13, which can ensure that the control board 8 and the card plate 7 move in a straight line.

[0025] The outer surface of the control plate 8 is slidably connected to a top plate 9, which is a wedge-shaped structure and is slidably connected to the outer surface of the guide sleeve body 1. When the top plate 9 moves upward, it can push the control plate 8 to move, and can further drive the clamping plate 7 to move and enter the interior of the fixing hole 5.

[0026] A spring 14 is sleeved on the outside of the limiting rod 13, one end of the spring 14 is fixedly installed on one side of the control board 8, and the other end of the spring 14 is fixedly installed on the inner wall of the fixing box 12. When the top plate 9 is out of contact with the control board 8, the spring 14 can pull the control board 8 to reset. At this time, the control board 8 drives the card plate 7 to break away from the contact with the fixing hole 5 and can contact the fixation of the card plate 7.

[0027] A moving ring 10 is fixedly installed on the lower surface of the top plate 9, and the outer surface of the moving ring 10 is slidably connected to the outer surface of the guide sleeve body 1. By pushing the moving ring 10 to move, multiple groups of top plates 9 can be driven to move at the same time, and multiple groups of control boards 8 can be driven to move at the same time, which facilitates the synchronous movement of multiple groups of card plates 7.

[0028] Multiple groups of support plates 15 are fixedly installed on the outer surface of the guide sleeve body 1. The outer surface of the support plate 15 is slidably connected to the inside of the top plate 9. The movement of the top plate 9 can be controlled by the support plate 15, and the top plate 9 can be controlled to move vertically outside the guide sleeve body 1, ensuring that the top plate 9 can smoothly enter the interior of the fixed plate 4 when moving, thereby ensuring stability during connection.

[0029] The lower surface of the movable ring 10 is slidably connected to a fixed ring 11. The outer surface of the fixed ring 11 is threadedly connected to the outer surface of the guide sleeve body 1. By rotating the fixed ring 11, the movable ring 10 can be pushed to move. The threaded connection between the fixed ring 11 and the guide sleeve body 1 is relatively stable.

[0030] A mounting hole 16 is provided inside the fixing ring 11, and a fixing bolt 2 17 is connected to the internal thread of the mounting hole 16. The outer surface of the fixing bolt 2 17 is slidably connected to the inside of the guide sleeve body 1. During the rotation of the fixing ring 11, force can be applied to the fixing ring 11 through the mounting hole 16 and tools. After the position of the fixing ring 11 is fixed, the fixing ring 11 can be connected to the guide sleeve body 1 through the fixing bolt 2 17. At this time, the fixing ring 11 will not rotate, which can ensure the stability of the connection between the fixing plate 4 and the clamping plate 7.

[0031] During installation, first connect the fixing frame 2 and the connecting workpiece through the fixing bolt 3, and connect the guide sleeve body 1 to the fixing frame 2. At this time, the fixing box 12 will enter the interior of the fixing plate 4, and rotate the fixing ring 11 through the installation hole 16. When the fixing ring 11 rotates, it can push the movable ring 10 to move upward, and the movable ring 10 can drive the top plate 9 to move. The top plate 9 pushes the control plate 8 to move to the outside of the fixing plate 4, and the control plate 8 can drive the card plate 7 to enter the interior of the fixing hole 5. At this time, the card plate 7 can fix the guide sleeve body 1. When disassembling, rotate the fixing ring 11 in the opposite direction and drive the movable ring 10 to move downward. Under the pull of the spring 14, the control plate 8 will drive the card plate 7 to move. At this time, the card plate 7 will be out of contact with the fixing hole 5, and the guide sleeve body 1 can be quickly disassembled.
