Detailed Description

In order to explain the technical content, the achieved objects and the effects of the present invention in detail, the following description is made in conjunction with the embodiments and the accompanying drawings.

As fig. 1 is a tightening frock of angle joint, including sleeve 1, first baffle 2 and second baffle 3, sleeve 1, first baffle 2 and second baffle 3 are made by iron, wherein:

the first baffle 2 and the second baffle 3 are fixedly arranged on the upper end surface of the sleeve 1 and are respectively arranged on two sides of any longitudinal section of the sleeve 1, as shown in fig. 2 and 3, the inner side surface of the first baffle 2 is a first mounting surface 21, the inner side surface of the second baffle 3 is a second mounting surface 31, and the first mounting surface 21 is parallel to the second mounting surface 31. The first mounting surface 21 and the second mounting surface 31 are used for engaging an angle joint.

The lower end of the sleeve 1 is provided with a sleeve joint hole 11 for sleeve joint of a spanner.

The use method of the screwing tool for the angle joint comprises the following steps:

glue is firstly applied to the end drawing of the angle joint loader, and the joint is screwed into the corresponding hole position of the engine or the part by hand, so that two to three teeth are formed. Then the first baffle 2 and the second baffle 3 of the tightening tool are arranged on two sides of a corner of the angle joint, and the connecting end of a torque wrench or a fixed torque wrench is inserted into the sleeve hole 11 at the lower end of the sleeve 1.
