• a hauling rope coiled on the turntable, with the housing provided with a rope hole for drawing out the hauling rope, the handle being provided with a button partially exposed out of the housing;
• a guide sleeve, fixed in the housing, provided inside with a guide hole extending along the radial direction of the turntable;
• a tab, in linkage with the button, slidably arranged in the guide hole of the guide sleeve, with a return spring connected between the tab and the guide sleeve;
• and
• a plurality of circumferentially spaced teeth, engaging with the tab, are formed circumferentially around the turntable;
• wherein in a natural state, under the action of an elastic force of the return spring, the tab is separated from the teeth, and the turntable can rotate freely;
• after the button is pressed, the tab makes a linkage action to move inwardly along the radial direction of the turntable and engages with the teeth, such that the turntable is locked circumferentially,
• wherein the button includes a button body partially exposed out of the housing, and the button body is provided at the rear portion with a hinged end hinged in the housing and at the front portion with a drive end abutting against the outer end of the tab, and
• wherein when the button is pressed, the hinged end of the button rotates counterclockwise around a hinged point and the drive end rotates counterclockwise to abut against the tab to move inwardly in a radial direction of the turntable.
