[0020] The specific implementation of the utility model will be further described in combination with the drawings and examples. The following examples are only used to more clearly illustrate the technical scheme of the utility model, and cannot limit the protection scope of the utility model.

[0021] The technical scheme of the specific implementation of the utility model is:

[0022] In a specific example, as Figure 1 The utility model provides a kind of elevator traction rope head fixing device, including rope head seat 1, guide shaft 2 and rope head shaft 3;

[0023] The rope head seat 1 is vertically arranged, and two avoiding openings 11 are symmetrically arranged on the rope head seat 1, and the avoiding openings 11 are vertically arranged.

[0024] The guide shaft 2 is located at the front side of the rope head seat 1, and the guide shaft 2 is connected with the top of the rope head seat 1.

[0025] The rope head shaft 3 is located at the rear side of the rope head seat 1, and the rope head shaft 3 is connected with the bottom of the rope head seat 1.

[0026] The above scheme is used: the elevator traction rope head fixing device of the utility model is used, the traction steel band is wound around the guide shaft 2, then passes through the avoiding opening and surrounds the rope head shaft 3 for one week, and the end of the traction steel band is clamped by the chuck, so as to fix the traction steel band on the rope head shaft 3.

[0027] In another specific embodiment, as shown in Figure 1 The top of the rope head seat 1 is provided with a reinforcing support 4, and the guide shaft 2 is arranged in the reinforcing support 4.
