Detailed Description

The technical scheme of the invention is further described in detail in the following with the accompanying drawings of the specification.

As shown in fig. 1 and fig. 2, the pagoda joint disassembling tool of the present invention comprises a tool bit, a pressing clamp 3, a connecting rod 4, a small pressing clamp 5, an adjusting screw 6, a clamp body 7, an upper joint, a lower joint and a spring 8. The upper joint and the lower joint are respectively hinged with one end of the pressing clamp 3 and one end of the clamp body 7.

One end of the upper caliper in the tool bit is inserted into the slot of the upper joint and is fixedly connected with the caliper body 7. The lower joint is inserted into the slot of the lower caliper 2 and is fixedly connected. One end of the connecting rod 4 is hinged with the pressing clamp 3, and the other end of the connecting rod 4 is supported in the inner sliding groove of the clamp body 7. One end of the spring 8 is fixed on the lower joint, and the other end is fixed on the pliers body 7. The adjusting screw 6 is screwed at the end part of the forceps body 7, and the inner end of the adjusting screw 6 is positioned in the inner sliding groove of the forceps body 7, thereby limiting the other end of the connecting rod 4. The small pressing pliers 5 are fixed on the inner side of one end of the pressing pliers 3, when the pressing pliers are pressed tightly, the small pressing pliers 5 are contacted with the lower side of the connecting rod 4, and when the pressing pliers need to be opened, the small pressing pliers 5 are pushed to play a role in assisting power.
