Screws are used to fix the coil spring on the drum, and the coil spring is connected to the inner wall of the drum through interconnected gears and extension springs.

In this embodiment, after the power line is pulled out, the position can be limited by the cooperation of the gear and the tension spring, and the winding spring can be used to reset the winding, which improves the shortcomings of the prior art that need to set buttons and install motors

Preferably, the drum is a plastic drum.

The purpose of choosing a plastic drum is to save manufacturing, maintenance and replacement costs.

Preferably, the wire reel further includes: a wire reel iron box placed outside the automatic wire reel.

The setting of the iron shell of the wire reel in this embodiment prevents the cable from wearing and tearing and prolongs the service life.

Preferably, the wire reel further includes: a wire reel bracket fixed at both ends of the rotating shaft to allow the rotating shaft to rotate.

The wire reel is installed on the wall or on the roof of the operating room through the wire reel bracket to make the site tidy and easy to use.

Preferably, the power line is connected with the terminal and wound on the drum.

Preferably, the plug at the end of the transmission line is provided with seven jacks, which respectively correspond to a ground wire, a neutral wire, a live wire and two sets of twisted pairs.

The above-mentioned embodiment is proposed as a preference, and is not limited to the enumerated form.

It can be seen from the above-mentioned technical scheme that the embodiment of the present invention guarantees the power transmission of the reel and the functional basis of the reel by setting the rotating shaft, the rotating drum and the connecting terminal and cooperating with the electrification performance of the carbon brush and the wire collecting ring. On the other hand, the gear at the end of the drum and the extension spring are used to limit the position when the transmission line on the drum is pulled to the required position, and the winding of the transmission line is restored through the coil spring, thus overcoming the existing The shortcomings of high power consumption and high cost of electric coiling equipment in the technology have achieved the technical effects of flexible cable stretching and retraction, simple structure and energy saving.
