[0027] The end of the floating sleeve 6 on one side of the retaining spring sleeve 8 is elastic.

[0028] First, manually remove the retaining spring sleeve 8, and then manually place the retaining spring 15 on the inclined surface of the retaining spring sleeve 8, and then install the retaining spring sleeve 8 with the retaining spring 15 on the sliding guide rod 4. During operation, the retaining spring pressure head of the shaft moves downward, and when the lower end surface of the retaining spring sleeve 8 contacts the end of the shaft, the retaining spring sleeve 8 no longer moves downward. At this time, the floating sleeve 6 presses the retaining spring 15 downward, and the retaining spring 15 is gradually expanded on the inclined surface of the retaining spring sleeve 8 until the retaining spring 15 moves down to the retaining spring groove of the shaft, and the retaining spring 15 is in place.

[0029] In some scenarios, an external thread is provided on the top of the sliding guide rod 4, and the retaining spring sleeve 8 and the sliding guide rod 4 are matched through threads to achieve the detachable relationship between the retaining spring sleeve 8 and the sliding guide rod 4; in some scenarios, an elastic plunger 13 is provided at one end of the sliding guide rod 4, and the retaining spring sleeve 8 is engaged on the elastic plunger 13 to achieve the detachable relationship between the retaining spring sleeve 8 and the sliding guide rod 4; in some other scenarios, the retaining spring sleeve 8 and the sliding guide rod 4 can also be in other ways, as long as the retaining spring sleeve 8 and the sliding guide rod 4 are detachable.

[0030] In some scenarios, the port of the floating sleeve 6 on one side of the retaining spring sleeve 8 is made of elastic material, so that the port of the floating sleeve 6 on one side of the retaining spring sleeve 8 is elastic. The elastic material is an existing material, such as rubber.

[0031] In some embodiments, the shaft retaining spring pressure head includes a proximity switch 14, which is located on the side of the floating sleeve 6 away from the retaining spring sleeve 8. A detection push rod 9 and a detection plate 10 are installed between the proximity switch 14 and the floating sleeve 6. One end of the detection push rod 9 is connected to one side of the floating sleeve 6, and the other end is connected to the detection plate 10.

[0032] When in use, when the circlip sleeve 8 has the circlip 15, the circlip 15 moves upward against the floating sleeve 6, and the floating sleeve 6 pushes the detection push rod detection piece 10 to move upward. The proximity switch 14 has a signal, indicating that the circlip 15 is in place, preparing for the formal installation of the circlip 15.

[0033] In some embodiments, the shaft retaining spring pressure head includes an upper pressing assembly, which is used to press down the floating sleeve 6 so that the downward moving floating sleeve 6 squeezes the retaining spring 15 on the retaining spring sleeve 8, and the retaining spring 15 is gradually expanded on the inclined surface of the retaining spring sleeve 8 until the retaining spring 15 moves down into the retaining spring groove of the shaft.

[0034] In some cases, the upper pressing assembly includes a fixing seat 1, a replacement head 2 is placed in the inner cavity of the fixing seat 1, a pressure head spring 12 is installed on the replacement head 2, and the other end of the pressure head spring 12 is installed on the sliding guide rod 4;

[0035] A sliding sleeve 3 is provided between the fixed seat 1 and the floating sleeve 6, and the sliding sleeve 3 is sleeved on the sliding guide rod 4;

[0036] In some scenarios, there is a gap between the sliding sleeve 3 and the fixed seat 1; in some scenarios, there is a gap between the sliding sleeve 3 and the floating sleeve 6; in some scenarios, there is a gap between the sliding sleeve 3 and both the fixed seat 1 and the floating sleeve 6;

[0037] When in use, the fixed seat 1 is pressed down, so that the shaft retaining spring pressure head moves downward as a whole, until the lower end surface of the retaining spring sleeve 8 contacts the shaft end, and the retaining spring sleeve 8 stops moving downward; the fixed seat 1 is continued to be pressed down, and the fixed seat 1 squeezes the floating sleeve 6, so that the floating sleeve 6 moves downward to squeeze the retaining spring 15 on the retaining spring sleeve 8, and the retaining spring 15 is gradually expanded on the inclined surface of the retaining spring sleeve 8 until the retaining spring 15 moves down to the retaining spring groove of the shaft.

[0038] In some embodiments, the sliding sleeve 3 and the floating sleeve 6 are connected through a connecting rod 7, a connecting plate 5 and a floating sleeve spring 11. One end of the connecting rod 7 is connected to the floating sleeve 6, and the other end is connected to the connecting plate 5. One side of the connecting plate 5 is connected to the floating sleeve spring 11, and one end of the floating sleeve spring 11 is connected to the sliding sleeve 3.

[0039] When in use, the floating sleeve 6 is moved and reset by the floating sleeve spring 11. For example, at the beginning, the retaining spring 15 is installed on the retaining spring sleeve 8, squeezing the floating sleeve 6 to cause the floating sleeve 6 to deviate.

[0040] In some embodiments, a dividing pin 16 and an anti-rotation bolt 17 are installed on the fixed seat 1. The dividing pin 16 is used to limit the axial movement of the replacement head 2 relative to the fixed seat 1; the anti-rotation bolt 17 is used to limit the circumferential rotation direction of the replacement head 2 relative to the fixed seat 1, so as to achieve a stable and detachable installation of the replacement head 2 on the fixed seat 1.

[0041] Working principle:

[0042] During operation, the circlip sleeve 8 is manually removed first, and then the circlip 15 is manually placed on the circlip sleeve 8, and then the circlip sleeve 8 with the circlip 15 is installed on the pressure head. With the circlip 15 on the circlip sleeve 8, the circlip 15 pushes the floating sleeve 6 to move upward, and the floating sleeve 6 pushes the detection push rod detection piece 10 to move upward. The proximity switch 14 has a signal, indicating that the circlip 15 is in place. At this time, the pressure head works and moves downward. When the lower end surface of the circlip sleeve 8 contacts the shaft end, the circlip sleeve 8 no longer moves downward, and the pressure head spring 12 is compressed, and the upper part of the pressure head continues to press downward, so that the connecting plate 5 completely contacts the floating sleeve 6, and the floating sleeve 6 squeezes the circlip 15 downward, and the circlip 15 is gradually expanded on the inclined surface of the circlip sleeve 8 until the circlip 15 moves down to the circlip groove of the shaft, and the circlip 15 is in place.
