The side of the threaded rod 34 close to the threaded rod 36 contacts the outer side of the threaded rod 36, and the outer side of the threaded rod 36 contacts the inner side of the threaded limiting sleeve 32, so that the cross limiting plate 34 inside the threaded limiting sleeve 32 can be squeezed by the threaded rod 36, and then the cross limiting plate 34 is squeezed outward, and the outer side of the end of the threaded rod 36 away from the threaded limiting sleeve 32 is fixedly connected to one end of the three guide rods 37, thereby increasing the fixing effect between the threaded rod 36 and the guide rods 37, and the end of the guide rod 37 away from the fixed block 38 contacts one end of the limiting roller 31, and then the guide rod 37 can be used to limit the threaded rod 36 to prevent excessive rotation and movement.

[0028] Example 2
[0029] like Figure 1-3As shown, the protection mechanism 2 includes a fixing plate 21, both ends of one side of the fixing plate 21 are provided with limit posts 22, both ends of the side of the fixing plate 21 away from the limit posts 22 are provided with connecting plates 23, the top of the fixing plate 21 is provided with a protection box shell 24, one side of the connecting plate 23 is provided with a fixing rod 25, the two ends of one side of the fixing plate 21 are respectively fixedly connected to the bottom ends of the two limit posts 22, the inner parts of the two ends of one side of the protection box shell 24 are respectively clamped with the outer sides of the two limit posts 22, so that the fixing effect between the fixing plate 21 and the protection box shell 24 can be better increased by installing the limit posts 22, and the fixing plate 21 is away from the limit posts The two ends of one side of the positioning column 22 are fixedly connected to the bottom ends of the two connecting plates 23, and one side of the connecting plate 23 is fixedly connected to one end of the fixing rod 25. The two ends of one side of the protection box shell 24 away from the limiting positioning column 22 are fixedly connected to the outer sides of the two limiting rollers 31, thereby increasing the connectivity between the protection box shell 24 and the rotation limiting mechanism 3. The end of the fixing rod 25 away from the connecting plate 23 is fixedly connected to the inside of one end of the threaded limiting sleeve 32, so that the fixing effect between the connecting plate 23 and the threaded limiting sleeve 32 can be increased by installing the fixing rod 25, and the connection effect between the rotation limiting mechanism 3 and the protection mechanism 2 can be increased.
[0030] Working principle:
[0031] like Figure 1-6As shown, the protective mechanism 2 installed on one side of the hob shaft body 1 can better play a protective effect, the installed fixing plate 21 can better facilitate the installation and fixation of the device to increase stability, the installed limiting clamping column 22 can better increase the fixing effect between the fixing plate 21 and the protective box shell 24, the connecting plate 23 installed on the fixing plate 21 can better facilitate the connection between the protective mechanism 2 and the rotation limiting mechanism 3, the installed protective box shell 24 can better play a protective effect, and the installed fixing rod 25 can increase the connection between the connecting plate 23 and The connection effect between the threaded limiting sleeve 32 can further provide fixed support for the threaded limiting sleeve 32, and the sliding connection between the installed limiting roller 31 and the threaded limiting sleeve 32 can better facilitate the limiting roller 31 to rotate on the threaded limiting sleeve 32. The limiting groove 33 drilled inside the threaded limiting sleeve 32 can better facilitate the limiting effect of the cross limiting plate 34. The installed spring 35 can better perform the elastic reset effect on the cross limiting plate 34 to prevent the cross limiting plate 34 from continuously limiting the limiting roller 31. Through the threaded connection between the installed threaded rod 36 and the threaded limiting sleeve 32, it is easier to squeeze the inside of the threaded limiting sleeve 32 when the threaded rod 36 rotates, so that the cross limiting plate 34 inside the threaded limiting sleeve 32 squeezes outward to limit the limiting roller 31. The guide rod 37 installed on the threaded rod 36 can prevent the threaded rod 36 from moving too far when it moves, thereby increasing the fixing effect of the limiting roller 31. The installed fixing block 38 can better facilitate the transmission of the rotation effect of the rotating sleeve 39, and has a lateral movement effect. The installed rotating sleeve 39 can better facilitate the user to limit the use of the rotating limiting mechanism 3. The installed rotating limiting mechanism 3 can better facilitate the user to limit and fix the protection box shell 24 inside the protection mechanism 2, thereby increasing the stability of the protection box shell 24. Due to the simple operation, it is easier for the user to use it conveniently, avoiding the situation in which the connection points of the previous protection box all use a simple locking method, resulting in general stability and protection effect, and further increasing the safety of the staff at work.
