Abstract
The utility model discloses a bolt for a transmission device. The bolt comprises a head part, a screw and an external part bearing rod, wherein a bearing cavity is formed inside the head part, a circle of internal threads are formed inside the bearing cavity; the screw is connected with the head part; the screw comprises a transitional part, a threaded part and a puncturing part; the transitional part, the threaded part and the puncturing part are sequentially connected; external threads are formed on the threaded part; the external bearing rod is fixed on the head part through internal threads; the end part of the external bearing rod serves as an operation part. According to the utility model, the bearing cavity is arranged at the head part of the bolt; the external bearing rod is fixed on the bearing cavity; the operation length of the bolt is increased through the external bearing rod. Therefore, the situation that the bolt cannot be fixed due to an excessively small arrangement space is avoided, and the bolt has the characteristics of simple structure and convenient use.
Description
Technical field
The utility model relates to transmission device field, is specifically related to a kind of transmission device bolt.
Background technique
Bolt is widely used in various machinery.When use, the part which floor bolt need to be linked together through, the head of bolt is clamped in part surface, the other end nut check of bolt, but bolt is in the time of urgent or loading torque, need to prevent bolt rotation and realize the urgent of bolt with the head of professional tool clamping bolt or specialized designs limit structure, but for the place that cannot put in professional tool or layout position-limit mechanism because arrangement space is too little, just there is the problem that cannot tighten because of self idle running in bolt.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of transmission device bolt, one carrying cavity is set on the head of bolt, external bearer bar is fixed on described carrying cavity, by external bearer bar, the working length of bolt is extended, avoid bolt because of the too little situation that cannot be fixing of arrangement space, there is feature simple in structure, easy to use.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of transmission device clamping bolt, comprising:
One head, offers a carrying cavity in described head, a circle internal thread is set in described carrying cavity,
One screw rod being connected with head, described screw rod comprises a transition part, a screw section and puncture portion, described transition part, screw section and the three of puncture portion connect successively, on described screw section, are provided with outside thread,
One external bearer bar, described external bearer bar is fixed on described head by internal thread, and described external bearer boom end is an operation unit.
In a preferred embodiment of the present utility model, described internal thread is contrary with described externally threaded hand of spiral.
In a preferred embodiment of the present utility model, described operation unit is a rectangular block, is provided with processing groove on rectangular block.
By technique scheme, the beneficial effects of the utility model are:
One carrying cavity is set on the head of bolt, external bearer bar is fixed on described carrying cavity, owing to being provided with external bearer bar, in fact the head of bolt is extended, people are to outside carrier bar twisting operation time, drive the twisting of the bolt being connected with external bearer bar, avoid occurring that bolt is because of the too little problem that cannot be fixing of arrangement space; Once bolt is fixing complete, external bearer bar departs from bolt; The puncture portion that bolt end is set can, by quick bolt access arrangement, have feature simple in structure, easy to use.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
