[0021] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] Embodiment 1
[0023] Figure 1 A specific embodiment of the utility model of a safety clutch disassembly and assembly tool is used, comprising a columnar body 1 that can pass through the axis of the safety clutch and fix the safety clutch, and a gear pressing assembly 2 that tightens and presses down the driving gear of the safety clutch is installed on the upper end of the columnar body 1. Through the columnar body 1 that can pass through the axis of the safety clutch and fix the safety clutch, and then through the gear pressing assembly 2 on the upper end of the columnar body 1, the driving gear of the safety clutch is continuously tightened and pressed down, so that the driving gear of the safety clutch is gradually separated from the adjusting nut, so that the adjusting nut can be easily unscrewed, and then the nut is slowly loosened, and the spring force under the driving gear is slowly released, making disassembly safe and convenient.
[0024] In this embodiment, a spline groove that matches the axis of the safety clutch is opened at the lower end of the columnar body 1, and the safety clutch is fixed by the spline 11.
[0025] In this embodiment, the gear pressing assembly 2 refers to a thread 21 provided at the upper end of the columnar body, and a nut 22 is screwed on the thread to tighten and press down the driving gear at the upper end of the safety clutch penetrating the columnar body. The gear pressing assembly 2 also includes a gasket 23, which is used to pad between the safety clutch and the nut to protect the driving gear of the safety clutch. By continuously tightening the nut 22, the spring inside the safety clutch acts on the lower end of the driving gear, so that the force of the nut 22 acts on the driving gear of the safety clutch, and the spring at the lower end of the driving gear is continuously compressed, so that the adjusting nut of the safety clutch is gradually separated from the driving gear, reducing the friction between the adjusting nut and the driving gear, so that the adjusting nut can be easily disassembled. After the adjusting nut is disassembled, the nut 22 is slowly loosened to slowly release the spring force under the driving gear, making the disassembly safe and convenient.
[0026] In this embodiment, a boss 12 is further provided at the lower end of the columnar spline 11 for preventing the safety clutch from continuing to move downward, and the outer radius of the boss 12 is greater than the radius of the hollow of the axis of the safety clutch. By providing the boss 12, after the column passes through the safety clutch and the spline groove inside the safety clutch is engaged with the spline 11 of the columnar body, the columnar body does not continue to slide downward on the columnar body.
[0027] In this embodiment, the lower end of the boss 12 is also provided with a second column 13 for fixing the column, the second column 13 is inserted into a fixed hole 3, the inner diameter of the hole 3 matches the outer diameter of the second column, the depth of the hole is greater than the length of the second column 13, and the second column and the column are on the same axis. In order to facilitate outdoor use, a component capable of fixing the column is also required. In this embodiment, the second column 13 is fixed by inserting it into a fixed hole 3, so that the entire column is fixed, so that the safety clutch can be stably disassembled. In this embodiment, the hole 3 can be fixed by using a crossed T-shaped frame 31 or a cross, the hole 3 is fixed to the intersection 311 of the T-shaped frame or the cross, a through hole is provided on the T-shaped frame or the cross, and the T-shaped frame or the cross is fixed to the ground or other table tops by screws.
[0028] In this embodiment, a through hole 14 is provided on the boss 12, and a rod-shaped body 4 passes through the through hole 14 for rotationally adjusting the columnar body, and the axis of the through hole is perpendicular to the axis of the columnar body. By inserting the rod-shaped body 4 into the through hole 14, the columnar body can be fixed at a suitable angle by holding the rod-shaped body, and then the nut at the upper end of the columnar body can be tightened with a wrench, so that the nut continuously compresses the spring under the driving gear through the driving gear during the tightening process, so that the gap between the driving gear and the adjusting nut is increased, the friction force is reduced, and the adjusting nut is easily removed. After the adjusting nut is removed, the nut is slowly loosened to release the spring force, and then the driving gear is removed.
[0029] Embodiment 2
[0030] The difference between this embodiment and the first embodiment is that the fixing method of the columnar body is different. When working in the field, the first embodiment can be used. When there is a bench vise platform indoors, a clamp can be used to clamp the lower end of the boss for fixing. Then, the disassembly and assembly tool does not need the second columnar body and the hole-shaped body matching it.
[0031] Embodiment 3
[0032] The difference between this embodiment and the first embodiment is that the fixing method of the column is different. When working in the field, the first embodiment can be used. When there is a bench vise platform indoors, the second column can be clamped with a clamp for fixing. Then, the disassembly tool does not need the second column and the hole-shaped body matched therewith, and there is no need to change the structure of the disassembly tool, which is convenient for working outdoors and indoors. The second embodiment is only suitable for indoor work.
[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
