Problems solved by technology

[0003] However, in real life, when the retractable device is retracting and releasing the wire, when the wire is about to be pulled out, the retracting motor will be triggered to stop running. However, due to the effect of inertia, when the motor stops, the pulling force is relatively large. After a long time, it will cause damage to the wire or break the interface of the wire

Abstract

The invention relates to the field of take-up and pay-off devices, in particular to a take-up and pay-off device. The take-up and pay-off device comprises a fixed seat, a take-up and pay-off motor, alimiting elastic sheet, a wire outlet hole and a wire winding stand column where a wire is wound. The take-up and pay-off device further comprises an elastic protector. One end of the wire winding stand column is connected with the take-up and pay-off motor, and the other end of the wire winding stand column is connected with a hollow cavity on the fixed seat. The limiting elastic sheet is arranged at the joint of the take-up and pay-off motor and the wire winding stand column. The wire winding stand column is in a hollow shape. One end of the wire is located on the inner side of the wire winding stand column, and the other end of the wire penetrates the outer side of the wire winding stand column and is then connected with the wire outlet hole. The elastic protector is arranged on the outer side of the wire winding stand column in a surrounding manner and arranged below the limiting elastic sheet. According to the take-up and pay-off device, through forward operation of the take-up and pay-off motor, the wire is paid off through the wire outlet hole; when drawing-out force is reduced, the take-up and pay-off motor rotates reversely, and the wire is taken up to be wound around thewire winding stand column; and when the whole wire is drawn out, the elastic protector can achieve a protection and buffer function on the wire.

Description

technical field [0001] The invention relates to the field of retractable devices, more specifically, to a retractable device. Background technique [0002] The retractor is a tool commonly used in daily life. By retracting and retracting the wire, the object can be pulled up or put down. [0003] However, in real life, when the retractable device is retracting and releasing the wire, when the wire is about to be pulled out, the retracting motor will be triggered to stop running. However, due to the effect of inertia, when the motor stops, the pulling force is relatively large. After a long time, it will cause damage to the wire or break the interface of the wire. [0004] Therefore, it is necessary to propose a retractable device that solves the above problems. Contents of the invention [0005] In order to overcome at least one defect (deficiency) of the above-mentioned prior art, the present invention provides a retractable device. [0006] In order to solve the above...
