The inventors found, in several decades of working experience, the objective drawbacks of the prior art:
1. the main structural part is composed of castings, and can be manufactured only by opening a mold, so that the mold is high in investment cost and long in period.
2. When the main parameters of the product are changed, the product can be produced only by re-opening the mould, the investment cost is high, and the period is long.
3. When the main structural part of the pliers body is a casting, the blank machining allowance is large, and labor and time are wasted.
4. The casting is easy to have casting defects such as sand holes, air holes and the like in the production process, and the material cost is improved.
5. The main structural member of the clamp body has a complex shape, and defects are easy to generate during heat treatment quenching, so that the cost is increased; the iron casting is not easy to quench harden.
6. The components are complex in shape, so that the clamping is difficult during machining, the complex coefficients of the clamp and the cutter are improved, and the cost is increased.
7. The existing flat tongs have large friction force during adjustment.
8. A part of the existing product is that a screw is directly connected with a movable jaw, and when the jaw is wide, the screw occupies much space.
9. In the use process, often can drop a large amount of pieces in the inside crack of sleeper rail, and then influence the regulation of keeping silent and clearance difficulty.
