Abstract
The utility model relates to a quick chain broken apparatus, which belongs to the tool of cutting chains. The quick chain broken apparatus is mainly composed of a groove body, a handle and a top thread. The groove body is provided with a groove, a threaded hole and a circular hole. The threaded hole is arranged in the same shaft direction with the circular hole. One end of the top thread is provided with a top head, and the other end of the top thread is provided with the rotary handle. The top head is the same shaft with the top thread. The handle is connected with the groove body. The tip shaft of a chain aims at the circular hole of the groove body and the top thread can be screwed into the threaded hole when the quick chain broken apparatus is used. The top thread can be rotated by the rotary handle and the tip shaft can be butted out, and the purpose of cutting chains can be achieved.
Description
The utility model belongs to a kind of instrument that blocks chain.
Chain is indispensable transmission devices such as bicycle, motorcycle, lathe.Because long-term running wearing and tearing, chain often need block maintenance.And traditional method for cutting is with punching pin, hammer, and the tip axle of chain is gone out.Time-consuming in this way, effort, efficient is low, danger is big.In recent years occurred a kind of " chain rivet remover fast " on the market, it is to utilize push rod that two tip axles of same chain outer plate are ejected together with outer plate, to reach the purpose that splits off chain.And this method need eject two tip axles, time-consuming, effort, and manufacturing process complexity.
The purpose of this utility model be to provide a kind of manufacturing process easy, save time, laborsaving, only need once eject the quick China breakage device that a tip axle can split off chain.
The purpose of this utility model is achieved in that it includes cell body (1), handle (2) and jackscrew (3).It is characterized in that cell body (1) is provided with groove (4), screwed hole (5) and circular hole (6), one of jackscrew (3) is provided with cylinder top (7), and the other end is provided with handler (8).
Handle (2) is installed on the cell body (1).Screwed hole (5) and circular hole (6) are coaxial.Top (7) is coaxial with jackscrew (3).Jackscrew (3) is a helicitic texture.The external diameter of the internal diameter of circular hole (6) and top (7) is suitable with the tip axle of chain.The size of groove (4) is advisable can hold a chain.During use, chain is placed on the groove (4), tip axle is aimed at circular hole (6), and jackscrew is screwed into screwed hole (5), rotates jackscrew (3) with handler (8), can eject the tip axle of chain, with the purpose that realizes blocking chain.
The technological progress that the utility model is obtained: when blocking chain, an ejector pin axle saves time, laborsaving, simple and easy to do, and technology is easy, saves material.
Be that embodiment is further described the utility model below with the accompanying drawing:
As shown in the figure, handle (2) is connected with cell body (1).Screwed hole (5) and circular hole (6) same axially on.Top (7) is coaxial with jackscrew (3).The external diameter of the internal diameter of circular hole (6) and top (7) is suitable with the tip axle of chain.The big I of groove (4) is held a chain.Chain is placed on the groove (4), and tip axle is aimed at circular hole (6), rotates jackscrew (3), can eject the tip axle of chain, and chain can block.
