Abstract
The invention relates to a connecting structure of a diamond circle wrench. The connecting structure of the diamond circle wrench comprises a front wrench clip and a rear wrench clip, wherein the front wrench clip and the rear wrench clip are connected in a rotary mode, and the end portion of the rear wrench clip is connected with a handle in a rotary mode. The connecting structure of the diamond circle wrench is characterized in that the front wrench clip and the rear wrench clip are connected through a rivet, the rear wrench clip and the handle are connected through a rivet, the tail end of each rivet is sleeved with a gasket, and a circular-truncated-cone-shaped riveting portion is formed on the tail end portion of each rivet through forced extrusion. The connecting structure of the diamond circle wrench is simple in structure, rotary connection between each wrench clip and the handle is achieved in the mode that the rivets and the gaskets are combined, the wrench clips are prevented from falling off, and safety performance is greatly improved.
Description
Technical field
The present invention relates to geological prospecting apparatus field, relate in particular to diamond free pliers.
Background technology
Diamond free pliers is wear-resisting with it, non-slip while using, do not hinder the mounting or dismounting that are widely used in rope drilling tool that tube wall can extend the application life of boring tool.Diamond free pliers consists of clamp and handle, between the clamp of existing diamond free pliers, be all rotationally connected by pin between clamp and handle, it is fastening that the end of pin adds jump ring, in the diamond free pliers use procedure of this connected mode, be prone to the phenomenon that clamp comes off, need to repeatedly fix, when serious, also easily cause security incident.
Summary of the invention
The above-mentioned shortcoming that the applicant exists for the syndeton of existing diamond free pliers, studies and improves, and a kind of stable connection is provided, uses the syndeton of safe diamond free pliers.
The technical solution adopted in the present invention is as follows:
A kind of syndeton of diamond free pliers, comprise the front clamp and the rear clamp that are rotationally connected, the end of rear clamp is rotationally connected handle, it is characterized in that: between described front clamp and rear clamp, rear clamp and handle, by rivet, be connected respectively, the end of described rivet is nested with packing ring, and the terminal part of rivet is pushed and formed circular platform type caulking part by pressure.
Beneficial effect of the present invention is as follows:
The present invention is simple in structure, adopts the mode that rivet is combined with packing ring to realize being rotationally connected between clamp and handle, has avoided coming off of clamp, has greatly improved security performance.
Accompanying drawing explanation
Fig. 1 is three-dimensional structure diagram of the present invention.
Fig. 2 is the A-A place sectional view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
See Fig. 1 and Fig. 2, the present invention includes the front clamp 1 and the rear clamp 2 that are rotationally connected, the end of rear clamp 2 is rotationally connected handle 3, front clamp 1 is connected by rivet 4 respectively with 3, handle with rear clamp 2, rear clamp 2, the end of rivet 4 is nested with packing ring 5, the terminal part of rivet 4 is pushed and is formed circular platform type caulking part 41 by pressure, and caulking part 41 stops coming off of packing ring 5 completely, improves the usage safety performance of diamond free pliers.
More than describing is explanation of the invention, is not the restriction to invention, and limited range of the present invention is referring to claim, and without prejudice to spirit of the present invention in the situation that, the present invention can do any type of modification.
