DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0020] Referring to Figures 1-3 , a motor test bench includes a workbench 1. On the left side of the top of the workbench 1, a support frame 2 is fixedly installed. On the left side of the inner cavity of the support frame 2, a transmission rod 3 is rotatably connected. The right side of the transmission rod 3 penetrates through the support frame 2 and is fixedly connected to a rotating seat 8. On the left side of the outer side of the transmission rod 3, a worm gear 4 is fixedly sleeved. At the bottom of the inner cavity of the support frame 2, a worm 5 adapted to the worm gear 4 is rotatably connected. On the top left side of the rotating seat 8, a rectangular groove 9 is fixedly opened. On the front and rear sides of the top and bottom of the inner cavity of the rectangular groove 9, limiting rods 10 are fixedly installed. A moving plate 11 is movably sleeved on the outer side of the limiting rods 10. At the bottom of the inner cavity of the rotating seat 8, an electric telescopic rod 14 is fixedly installed. The output end of the electric telescopic rod 14 extends into the inner cavity of the rectangular groove 9 and is fixedly connected to the bottom of the moving plate 11.

[0021] In this embodiment, the top of the worm 5 penetrates through the support frame 2 and is fixedly connected to a rotating disc 6. On the left side of the top of the rotating disc 6, a handle 7 is fixedly installed. The outer side of the worm 5 is rotatably connected to the inner cavity of the support frame 2.
