[0006] As an optimal technical solution of a fixing pin auxiliary installer of the utility model, the limiting ring includes a second limiting tube, a fixing plate is arranged on the top of the second limiting tube, a fixing hole is opened in the center of the top of the fixing plate, and a second connecting groove is opened on the surface of the second limiting tube.

[0007] As a preferred technical solution of a fixing pin auxiliary installer of the utility model, the inner diameter of the second limiting tube is larger than that of the first limiting tube, and the diameter of the fixing hole is the same as the outer diameter of the connecting tube and the inner diameter of the first limiting tube.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0009] The fixing pin auxiliary installer of the utility model only needs one person to complete the operation. The presser is pressed with one hand, and the fixing pin is clamped out with tweezers, which reduces the number of operators and reduces the operation time and improves work efficiency. The device is easy to operate and easy to use, and the fixing pin installer can be universally used for fixing pins of different models, and only the limit ring needs to be replaced.

[0017] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0018] In the drawings, the same reference numerals all refer to the same components.

[0019] Example 1

[0020] like Figure 1-5 As shown, it includes an operating handle 1 and a limiting ring 2. The operating handle 1 includes an operating block 3. A connecting tube 4 is provided at the top center of the operating block 3. An annular tooth 5 is provided at the top of the connecting tube 4. The connecting tube 4 passes through the operating block 3. The limiting ring 2 includes a first limiting tube 6. A first connecting groove 7 is provided on one side of the surface of the first limiting tube 6.

[0021] Specifically, when in use, the limiting ring 2 is sleeved on the fixing pin surface of the wheel hub, and the first connecting groove 7 faces one side of the wheel hub wall, so that the first limiting tube 6 can be conveniently sleeved on the fixing pin surface of the wheel hub without being hindered by the wheel hub wall. At this time, the user supports the limiting ring 2 with one hand, and aligns the connecting tube 4 with the center of the first limiting tube 6 with the other hand to slide it into the first limiting tube 6 so that its annular tooth 5 contacts the top surface of the fixing pin. The user then grasps the operating block 3 with the other hand, presses the operating block 3 and rotates it 90° counterclockwise to remove the fixing pin inside the wheel hub, and the fixing pin can be taken out with tweezers. The set annular tooth 5 increases the friction between the first limiting tube 6 and the fixing pin, which facilitates the operation handle 1 to drive the fixing pin to rotate and disassemble. When installing, press the operating block 3 and rotate it 90° counterclockwise to install the fixing pin inside the wheel hub.

[0022] Furthermore, the limiting ring 2 includes a second limiting tube 10 , a fixing plate 8 is arranged on the top of the second limiting tube 10 , a fixing hole 9 is opened in the center of the top of the fixing plate 8 , and a second connecting groove 11 is opened on the surface of the second limiting tube 10 .

[0023] The inner diameter of the second position limiting tube 10 is larger than that of the first position limiting tube 6 , and the diameter of the fixing hole 9 is the same as the outer diameter of the connecting tube 4 and the inner diameter of the first position limiting tube 6 .

[0024] Specifically, when disassembling a large-sized fixing pin, the second limiting tube 10 is sleeved on the surface of the fixing pin and the connecting tube 4 is aligned with the fixing hole 9 so that the annular tooth 5 contacts the top surface of the fixing pin. The user then grasps the operating block 3 with the other hand, presses the operating block 3 and rotates it 90° counterclockwise to disassemble the fixing pin inside the wheel hub, and the fixing pin can be taken out with tweezers. The annular tooth 5 increases the friction between the first limiting tube 6 and the fixing pin, making it convenient for the operating handle 1 to drive the fixing pin to rotate and disassemble. When installing, press the operating block 3 and rotate it 90° counterclockwise to install the fixing pin inside the wheel hub.

[0025] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
