In the figure: 1. pulling a nose; 2. a pull tab; 3. a notch; 5. replacing the component; 51. a telescopic push rod; 52. fixing the rod; 53. a limiting rod; 54. a limiting groove.

Detailed Description

The present application will now be described in further detail with reference to the drawings, it should be noted that the following detailed description is given for illustrative purposes only and is not to be construed as limiting the scope of the present application, as those skilled in the art will be able to make numerous insubstantial modifications and adaptations to the present application based on the above disclosure.

Example 1

As shown in figure 1, a pull head pulling-on piece structure convenient to change, including locating pull nose 1 and pulling-on piece 2 on the pull head, be equipped with the confession on the pulling-on piece 2 and pull the breach 3 that nose 1 passed, pulling-on piece 2 through breach 3 with pull nose 1 swing joint, during the dismantlement, the user at first holds the pulling-on piece 2 with the hand to control pulling-on piece 2 and pass breach 3, realize dismantling pulling-on piece 2 fast.

As shown in fig. 2, a replacing assembly 5 is arranged at the notch 3, the replacing assembly 5 includes a telescopic push rod 51 and a fixed rod 52 which are oppositely arranged at two ends of the notch 3, one end of the telescopic push rod 51 facing the fixed rod 52 is hinged with a limit rod 53, a limit groove 54 which is clamped with the fixed rod 52 is arranged in the limit rod 53, the limit rod 53 is positioned at the inner side of the telescopic push rod 51, the turning direction is opened and closed towards the inner side of the notch 3, the rotating angle range of the limit rod 53 is 0-90 °, and one end of the telescopic push rod 51 is provided with a spring;

as shown in fig. 3, when the pull tab 2 is installed on the pull nose 1, the end of the pull tab 2 is held by a hand, the notch 3 on the pull tab 2 is aligned on the pull nose 1, the pull tab 2 is pushed towards the notch 3, so that the end of the pull nose 1 is arranged in the notch 3, under the action of the spring, the telescopic push rod 51 is pushed to slide towards the end of the fixed rod 52, at the moment, the distance between the end of the fixed rod 52 and the end of the telescopic push rod 51 is reduced, namely, the size of the notch 3 is gradually reduced, then, when the limit rod 53 is rotated to the state that the limit groove 54 is clamped with the fixed rod 52, the central axes of the telescopic push rod 51, the fixed rod 52 and the limit rod 53 are parallel to each other, and the notch 3 is changed to the closed state, at the moment, the pull tab 2 is stably installed on the pull nose 1, and the phenomenon that the pull tab falls off when a user pulls the pull tab 2 can be effectively avoided.

When the pull piece 2 is disassembled, a user firstly pokes the limiting rod 53 by hand to turn over the limiting rod 53, when the limiting rod 53 rotates by 90 degrees in the telescopic push rod 51 to the maximum angle, the central axes of the limiting rod 53 and the telescopic push rod 51 are in a mutually vertical state, then, the user holds the end part of the pull tab 2 by hand, aligns the notch 3 on the pull tab 2 with the end part of the pull nose 1, finally clamps the junction of the limit rod 53 and the telescopic push rod 51 at the end part of the pull nose 1, pulls towards the end part of the pull nose 1, under the blocking action of the limiting rod 53, the telescopic push rod 51 is pushed to slide in the pull tab 2, at the moment, the channel distance between the end part of the telescopic push rod 51 and the end part of the fixed rod 52 is gradually increased, when the channel distance is greater than the end size of the pull tab 1, the pull tab 2 is moved towards the direction away from the notch 3, so that the pull tab 1 is separated from the channel distance, and the pull tab 2 is conveniently and quickly detached.

The above examples only show some embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
