[0022] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment proposes a fixture for cement pole hoisting, comprising a base plate 1, a driving component is fixedly installed on the upper surface of the base plate 1, a pushing component is engaged at both ends of the driving component, and a clamping component is fixedly installed at both ends of the base plate 1;

[0025] The driving assembly includes a servo motor 2 fixedly mounted in the middle of the upper surface of the base plate 1, the output end of the servo motor 2 is spline-connected with an A gear 3, the A gear 3 is meshed with a B gear 4, the interior of the B gear 4 is fixedly connected with a rotating rod 5, the surface of the rotating rod 5 is rotatably connected with a support seat 6 through an A bearing, the support seat 6 is fixedly mounted on the upper surface of the base plate 1, and C gears 7 are fixedly mounted on both ends of the rotating rod 5. The servo motor 2 is started to rotate the A gear 3 to drive the B gear 4, so that the rotating rod 5 rotates on the support seat 6, and finally drives the C gear 7 to rotate;

[0026] The pushing component includes a D gear 8 meshing with the C gear 7. The internal spline of the D gear 8 is connected to a forward and reverse screw rod 9. The forward and reverse screw rod 9 is rotatably connected to a support 10 through a B bearing. Both ends of the forward and reverse screw rod 9 are threadedly connected to a limiting square rod 11. One end of the limiting square rod 11 is fixedly connected to a slider 12. The surface of the slider 12 is connected to a push frame 13. When the C gear 7 rotates, the D gear 8 on which the forward and reverse screw rod 9 is mounted follows its rotation and drives the D gear 8 to rotate, so that the forward and reverse screw rod 9 is pushed toward both ends or retracted inward. Pushing outward will cause the push frame 13 to move. When the push frame 13 moves up and down, the limiting square rod 11 moves in the push frame 13 through the slider 12, keeping the horizontal position of the limiting square rod 11 unchanged, while the push frame 13 moves up and down, thereby achieving a pushing effect.
