[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] The present invention provides a technical solution, a lifting tool for parts without lifting ears, please refer to Figure 1 , Figure 2 and Figure 3 ,include:

[0025] A lifting tool 1, wherein three equidistantly distributed connecting bolts 2 are respectively arranged on the front and rear sides of the upper end of the lifting tool 1, and the connecting bolts 2 are connected to the lifting tool 1 through threaded matching;

[0026] A protective pad 4 is arranged at the lower end of the lifting tool 1;

[0027] The top groove 5 is arranged at the middle position inside the upper end of the lifting tool 1 , and the top groove 5 and the lifting tool 1 are integrally formed.

[0028] See also Figure 2 and Figure 3 A square groove 8 is provided on both the front and rear sides of the top groove 5 , and the square groove 8 is connected to the top groove 5 , and the square groove 8 passes through the lifting tool 1 , and the square groove 8 is used for the L-shaped side plate 10 to pass through.

[0029] See also Figure 2 L-shaped side panels 10 are provided on both the front and rear sides of the upper end of the protective pad 4 located inside the square groove 8, and the L-shaped side panels 10 are fixedly connected to the protective pad 4.

[0030] See also Figure 1 , Figure 2 and Figure 3 A turntable 6 is rotatably installed inside the top groove 5 through the rotating shaft 3, and notches are set on the front and rear sides of the outside of the turntable 6. A T-shaped frame 7 is installed at the middle position of the upper end of the turntable 6, and the T-shaped frame 7 is fixedly connected to the turntable 6. The T-shaped frame 7 is used to rotate the turntable 6.

[0031] See also Figure 2 and Figure 3 Bottom grooves 12 are provided on both sides of the lower end of the turntable 6, and spring plates 13 are installed inside the bottom grooves 12. A limiting ball 14 is provided at the lower end of the spring plates 13. Four limiting holes 9 evenly distributed along a ring are provided inside the top groove 5, and the limiting balls 14 are adapted to the limiting holes 9. The limiting balls 14 are combined with the limiting holes 9 so that the turntable 6 is limited and fixed.
