Detailed Description
In order to clearly understand the above objects, features and advantages of the present invention, the present invention will be further described with reference to the accompanying drawings and embodiments. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.
A clamp tool for a safety hook comprises an upper template 1, a vertical plate 2, a lower bottom plate 3, a bidirectional screw rod 4, a slider nut 5, a round long pipe nut 501, a large positioning block 6, a small positioning block 7 and an ejector block 8. As shown in fig. 1, two vertical plates 2 are oppositely arranged at the bottom of an upper template 1 along the length direction, the upper template 1 is fixedly connected with a lower bottom plate 3 through the vertical plates 2, and the upper template 1, the vertical plates 2 and the lower bottom plate 3 enclose a cavity. As shown in fig. 2, the upper plate 1 is provided with a large positioning block 6, a small positioning block 7 and a top block 8 for positioning the safety hook. The large positioning blocks 6 are arranged along the length direction of the upper die plate 1 and in the middle of the upper die plate 1, and the small positioning blocks 7 are arranged on two sides of the large positioning blocks 6 at equal intervals. Set up kicking block 8 between the adjacent little locating piece 6 of homonymy, kicking block 8 is the arrow point shape, and its front end is towards big locating piece 6, and two inclined planes of front end are used for the flexion of fixed safety hook, and big locating piece 6 is opened with kicking block 8 relative position has the constant head tank 601 that matches with the drilling end of safety hook, and the constant head tank sets up in pairs, and is relative with two inclined planes of kicking block front end respectively.
