[0022] As an implementation in the embodiment, as shown in Figure 3 and Figure 4 The limiting mechanism 4 includes a vertical plate 401, the vertical plate 401 is fixedly connected to the top end of the collecting cylinder 301, a circular rod 402 is inserted in the side end of the vertical plate 401, a straight groove plate 403 is fixedly connected to the side end of the circular rod 402, a clamping block 404 is fixedly connected to the side end of the straight groove plate 403, a spring 405 is sleeved on the outer end of the circular rod 402, one end of the spring 405 is fixedly connected to the inside of the straight groove plate 403, the other end of the spring 405 is fixedly connected to the side end of the vertical plate 401, a pull rod 406 is fixedly connected to the top end of the straight groove plate 403, a certain amount of maintenance oil is injected into the cavity 203, the clamping block 404 is located between two bosses 304, the pull rod 406 is loosened, the spring 405 moves the straight groove plate 403, the clamping block 404 moves between the two bosses 304 to limit the push plate 303, the push plate 303 cannot move up or down, the piston rod 302 cannot be continuously pushed to inject the maintenance oil into the cavity 203, the hook 101 is regularly lubricated and maintained, the maintenance oil is quantitatively injected, and the excess maintenance oil is prevented from leaking and wasted.
[0023] Working principle: By placing the arc plate 1 2 and the arc plate 2 at the outer end of the hook 101, at this time, every two adjacent side plates 201 are aligned with each other, and at this time, by installing the fastening bolts 202 respectively, the fixation between the arc plate 1 2 and the arc plate 2 is completed, so that it is installed at the outer end of the hook 101, and each silicone pad 204 can be tightly attached to the outer wall of the hook 101. At this time, after the collecting cylinder 301 is rotated and removed from the threaded port 206, the collecting cylinder 301 is placed into the maintenance oil cylinder, and then the pull rod 406 is pulled. The pull rod 406 drives the straight groove plate 403 and the block 404 to move. At this time, the straight groove plate 403 moves and cooperates with the vertical plate 401 to press the spring 405 to shrink. At this time, the block 404 is no longer stuck between the two bosses 304. At this time, the piston rod 302 can be pulled to draw the maintenance oil into the collecting cylinder 301, thereby facilitating maintenance The maintenance oil is replenished by threading the collecting cylinder 301 into the threaded port 206. At this time, the piston rod 302 is pushed to inject the maintenance oil into the cavity 203 inside the arc plate 1 2. At this time, the maintenance oil in the cavity 203 flows to the outer end of the hook 101 through the circular hole 205. At this time, by pulling the arc plate 1 2 and the arc plate 2 to move along the outer end of the hook 101, and rotating the arc plate 1 2 and the arc plate 2, the maintenance oil can be evenly applied to the outer end of the hook 101, so that the hook 101 can be maintained regularly. The maintenance oil covering the outer end of the hook 101 can protect it, making it difficult for the hook 101 to come into contact with moisture in the air, preventing the hook 101 from rusting, and thus preventing the hook 101 from becoming brittle due to rust, thereby improving the strength and toughness of the hook 101, and thus preventing danger from occurring in the subsequent use of the hook 101.
[0024] By observing the number of times the inner boss 304 of the push plate 303 descends after the piston rod 302 is pushed, a certain amount of maintenance oil is injected into the cavity 203 so that the block 404 is located between two of the bosses 304. By loosening the pull rod 406, the spring 405 will move against the straight groove plate 403, driving the block 404 to move between the two sets of bosses 304 to limit the push plate 303. At this time, the push plate 303 cannot move up or down, and thus cannot continue to push the piston rod 302 to continue to inject maintenance oil into the cavity 203, thereby achieving regular oiling and maintenance of the hook 101, and the maintenance oil can be injected in a quantitative manner to avoid leakage and waste of excess maintenance oil.
