Embodiment 1

[0024] refer to figure 1 with figure 2 , a self-control type retractable tool, including a housing 1, a retractable tray 2 accommodated inside the housing, and a retractable article 3 whose inner end is fixed to the retractable tray and wound around the retractable tray. There is a Through hole 4, the free end of article 3 to be retracted passes through through hole, and we have also been provided with a handle position 10 on this retractable tool for the convenience of operation.

[0025] We see from the appearance point of view, such as figure 1 As shown, the product as a whole is a smooth and closed shell, on which there is only one through hole 4 for the articles 3 to be stored to pass through.

[0026] see figure 2 As shown in , the inner side of the storage tray 2 protrudes to form a ratchet 5, and also includes a pendulum that interferes with the ratchet. It is an upper pendulum 61 and a lower pendulum 62. The pendulums 61 and 62 are rotatably fixed inside the h...

Abstract

The invention relates to a self-controlled folding and unfolding tool and discloses the self-controlled folding and unfolding tool so as to meet the requirements of the folding and unfolding tool for folding and unfolding controllability. The tool comprises a housing, a folding and unfolding disc accommodated in the interior of the housing, and an object to be folded and unfolded with an inner end head fixed in the folding and unfolding disc. The object to be folded and unfolded twines around the folding and unfolding disc. A through hole is formed in the housing. The free end of the object to be folded and unfolded is penetrated through the through hole. Pawls are formed at protrusions inside the folding and unfolding disc. The self-controlled folding and unfolding tool further comprises swing hammers rotatably fixed inside of the housing through swing shafts. The swing hammers interference with the pawls. One ends, away from the pawls, of the swing hammers are gravity heads. Rotary planes of the swing hammers are intersected with the plane where the housing is located. The self-controlled folding and unfolding tool has following beneficial effects: the overall housing is enclosed despite the fact that a necessary through hole is penetrated through the free end of the object to be folded and unfolded; and by controlling the relations between the tool and the gravity direction, the interference relations between the swing hammers and the pawls can be controlled, thereby achieving rotary control of the folding and unfolding disc.

Description

technical field [0001] The invention relates to a self-control retractable tool. Background technique [0002] Retractable equipment, generally used for retracting and releasing ropes, measuring tapes, steel rulers, etc. It usually includes a casing, a retractable tray accommodated inside the casing, and a retractable item whose inner end is fixed to the retractable tray and wound around the retractable tray. When in use, the retracted articles are pulled out of the casing to realize the release of the retracted articles, and after use, they are rewound on the retractable tray to realize the retracted articles. [0003] In some cases, we expect to be able to control this retraction and release state. [0004] Most of the control methods in the current prior art are as follows: Figure 4 As shown, a ratchet 5 is provided on the outer side of the retractable tray 2, and the movement of the retractable tray is controlled through the interference of the locking mechanism 8 and...
