The utility model discloses a technical scheme as follows: the utility model provides a piston connecting rod erecting tool, includes the stereoplasm member, and the stereoplasm member includes anterior segment, interlude, back end, and the anterior segment is handheld portion, and the interlude is straight-bar A, and the anterior segment is straight-bar B, has the contained angle between straight-bar A and the straight-bar B, and the angle of contained angle is 120-150 degrees, and the surface of straight-bar B is unsmooth under stress state at least.
On the basis of the above scheme, preferably, the hard rod is a steel rod.
In addition to the above-described aspect, preferably, the surface of the straight rod B is uneven.
On the basis of the scheme, preferably, the straight rod B is sleeved with the rubber sleeve, and the straight rod B is tightly matched with the rubber sleeve.
On the basis of the scheme, the straight rod A is preferably sleeved with a flexible sleeve.
On the basis of the scheme, preferably, the straight rod A is connected with the straight rod B through the arc-shaped section, and the arc-shaped section is sleeved with the flexible sleeve.
On the basis of the above scheme, preferably, the arc-shaped section is formed by bending a hard rod piece.
On the basis of the scheme, the handle part is preferably formed by bending a steel bar for multiple times or fixedly connected with a handle through threads.
Compared with the prior art, the utility model discloses following beneficial effect has:
the tool is used for replacing fingers, so that the danger of smashing the fingers is avoided, meanwhile, the tool is long and thin and is easier to stretch into, and the assembly efficiency is improved.
The rubber sleeve is longer than the straight rod B, so that the front end of the straight rod B is protected, and hard contact and thread damage caused by the fact that the straight rod B is inserted into the threaded hole are avoided.
The rubber sleeve is sleeved on the straight rod B, when the straight rod B is inserted into the threaded hole, the straight rod B is easier to scrape in the threaded hole, the friction force is large, and the connecting rod is convenient to pull.

Detailed Description
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following description will refer to the accompanying drawings to describe specific embodiments of the present invention. It is obvious that the drawings in the following description are only examples of the invention, and that for a person skilled in the art, other drawings and embodiments can be derived from them without inventive effort.
Example 1
As shown in fig. 1, a piston connecting rod assembling tool includes a hard rod member, the hard rod member includes a front section 1, a middle section 2, and a rear section 3, the front section is a handheld portion, the middle section is a straight rod a, the front section is a straight rod B, an included angle is formed between the straight rod a and the straight rod B, the included angle is 120 degrees, the surface of the straight rod B is at least not smooth under a stress state, the unsmooth surface is the unsmooth surface of the straight rod B, and the hard rod member is a steel rod.
Through the design that the angle between the straight rod A and the straight rod B is 120 degrees,
when the connecting rod is installed, the crankcase is laid down, the crankshaft extends into the crankshaft from the connecting rod hole, when the upper end of the connecting rod hole is extended, the hard rod piece extends into the crankshaft accommodating space from the upper part of the connecting rod journal, the straight rod B is inserted into the threaded hole (the threaded hole positioned above) in the end part of the connecting rod, the rod A is straightened outwards, the end part of the connecting rod is pulled out to the lower part of the connecting rod journal, the connecting rod cover is closed, and the bolt is installed. The whole process replaces the finger with the instrument, does not have the danger of injuring the finger by a crashing object, and simultaneously, the instrument is long and thin, is changeed and stretches into, improves assembly efficiency.
In the scheme, the straight rod B is uneven in surface and easy to scrape in the threaded hole, so that the stress effect is good.
Example 2
The straight rod B is sleeved with the rubber sleeve, the straight rod B is in tight fit with the rubber sleeve, the length of the rubber sleeve is longer than that of the straight rod B, the front end of the straight rod B is protected, and hard contact and damage to threads when the straight rod B is inserted into the threaded hole are avoided.
