Description

Technical Field

[0001] The utility model belongs to the technical field of fixing tools, and in particular relates to a fixing tool for non-standard customized bolts. Background Art

[0002] Non-standard bolts are special sizes that are not included in the national standards and are generally used in applications with fewer parts. Bolts are tools that use the physics and mathematical principles of the inclined circular rotation and friction of an object to gradually tighten objects and parts. Bolts are a general term for fasteners.

[0003] Bolts need to be fixed during processing. In the prior art, they are generally clamped directly with flat-nose pliers or pressure blocks. This fixing method is relatively rough and is not suitable for non-standard customized bolts. The bolts may be squeezed out of the clamp during processing, resulting in poor fixing effect. At the same time, multiple bolts are required for fixing, which wastes time during disassembly and assembly, resulting in low production efficiency.

[0004] Therefore, in order to solve the above problems, it is necessary to design a fixing tool for non-standard customized bolts. Utility Model Content

[0005] The utility model aims to provide a fixing tool for non-standard customized bolts to solve the technical problems of unstable fixing and inconvenient assembly and disassembly of existing clamps.

[0006] In order to solve the above technical problems, the utility model provides a fixing tool for non-standard customized bolts, including:

[0007] A base plate and a support block symmetrically arranged on the base plate for supporting the bolt rod;

[0008] Two extrusion blocks with inclined surfaces are symmetrically arranged on the bottom plate and slidably connected to the bottom plate;

[0009] A lower pressing block is arranged between the two extrusion blocks and is slidably connected with the inclined surfaces of the two extrusion blocks;

[0010] The pressing block is suitable for sliding on the inclined plane when under pressure, so as to press the two pressing blocks to slide on the bottom plate like the corresponding supporting block side, so as to cooperate with the supporting block to clamp the bolt head.

[0011] Furthermore, a first countersunk through hole is provided on the lower pressing block;

[0012] The bottom plate is provided with threaded holes;

[0013] A bolt is engaged in the threaded hole; wherein

[0014] The bolt is suitable for penetrating the first countersunk through hole and then engaging with the threaded hole, so that the extrusion block is pressed down when the bolt is tightened.

[0015] Further, the bottom plate is provided with a guide groove;

[0016] A limiting portion is provided at the bottom of the extrusion block;

[0017] The limiting portion is suitable for sliding in the guide groove.

[0018] Furthermore, a guide portion is provided on the inclined surface of the extrusion block;

[0019] The two sides of the lower pressing block are provided with protrusions; wherein

[0020] The protrusion is adapted to the guide portion; and

[0021] The protrusion is suitable for sliding in the guide portion.

[0022] Further, the support block comprises: a placement portion;

[0023] The cross section of the placement portion is V-shaped.

[0024] Furthermore, at least two second countersunk through holes are provided on the bottom plate.

[0025] The beneficial effects of the utility model are:

[0026] (I) The utility model places the non-standard bolt on the placement part, with the bolt head located above the bottom plate. At this time, the bolt is tightened, and the bolt engages with the threaded hole to drive the pressing block to slide downward on the inclined surface, and the protrusion slides in the guide part. At this time, the extrusion block slides on the bottom plate under pressure, and the limiting part slides in the guide groove until the bolt head is tightly clamped with the support block. The non-standard bolt can be removed by loosening the bolt. Through the above steps, the effect of stable fixation and quick and convenient disassembly and assembly can be achieved.
