When the toggle element 520 is toggled or pressed, the reset element 530 can move synchronously with the toggle element.

Further, the reset member 530 further includes a spring 534 and a reset plate 535. This reset seat 531 middle part is established holding tank 536, be equipped with lift groove 537 respectively on the relative both sides cell wall of holding tank 536 down, reset plate 535 with the holding tank 536 shape matches each other down, just it is equipped with the tip relatively on the reset plate 537, the tip slip holding is in lift groove 537. The spring 534 is received in the lower receiving groove 536, and one end of the spring 534 abuts against the reset plate 535, and the other end of the spring extends out of the lower receiving groove to be sleeved on the sleeving connection post 526. The reset seat 531 is provided with a blocking portion 538 at one side of the lower receiving groove 536.

Referring to fig. 11, the locking member 600 is pivotally connected to the housing 10 between the rotary plate 20 and the locking button 500. The locking member 600 includes a pivot base 610, a pivot portion 620 disposed on the pivot base 610, a locking portion 640, and a pressing portion 630. Specifically, the housing 10 is provided with a mounting shaft 13, and a torsion spring 14 is wound on the mounting shaft 13. The housing 10 is provided with a stopper 15. One end of the torsion spring 14 abuts against the stopping member 15, and the other end of the torsion spring abuts against the pivot seat 610. The pivoting portion 320 is pivoted on the mounting shaft 13, and the locking portion 640 is engaged with the adjacent latch 21 on the rotary plate 20. The pressing portion 630 is engaged with the reset member 530.

Referring to fig. 3, 4 and 5, the toggle element 520 is toggled towards the handle portion 30, and the toggle element 520 drives the reset element 530 to move towards the handle portion 30 along the first sliding slot 511 of the mounting base 510. The pressing portion 640 enters the blocking portion 538, and the reset member 530 pushes the pressing portion 630, so as to rotate the locking member 600, so that the locking portion 640 rotates to be inserted between adjacent latch teeth 21 on the turntable 20, so as to lock the turntable 20, so as to prevent the turntable 20 from rotating, and release the traction rope or wind the traction rope. Poking piece 520 is poked towards rope outlet 40, poking piece 520 drives reset piece 530 along first sliding tray 511 to rope outlet 40 direction removes, press portion 630 to be located reset piece 530 below, reset piece 530 releases press portion 630, lock piece 600 resets, lock portion 640 stretches out between the adjacent latch 21 on carousel 20, thereby release carousel 20, carousel 20 can enough forward rotate release the haulage rope, can reverse the rolling haulage rope. When the toggle element 520 is pressed downwards, the toggle element 520 pushes the mounting base 510 to rotate around the first rotation axis until the limiting part 513 contacts the elastic part 514, and the mounting base 510 cannot rotate any more when being blocked by the elastic part 514. At this time, the reset member 530 pushes the pressing portion 630, so as to urge the lock member 600 to rotate until the lock portion 640 is partially inserted between the adjacent latches 21. If the turntable 20 rotates forward to release the pulling rope, the pulling rope is blocked by the locking part 640, if the turntable 20 rotates backward to wind the pulling rope, the latch 21 pushes the locking part 640, the pressing part 630 pushes the reset plate 535, and the compression spring 534 rises, so that the pivot joint 600 can rotate until the locking part 640 extends out of the adjacent latch 21, and the turntable 20 rotates backward to wind the pulling rope. After the pressing force disappears, the spring 534 resets to push the reset plate 535, and the elastic member 514 also pushes the mounting base 510 to reset. The locking part extends out of the position between the adjacent clamping teeth on the rotary disc to release the rotary disc. The pulling piece is continuously pressed or repeatedly pressed to roll the traction rope.

Specifically, the pivot seat 610 is in the shape of an open slot 612 surrounded by two side walls 611 and a bottom plate, one end of each of the two side walls 611 extends out of the pivot portion 620, the other end of each of the two side walls extends out of the locking portion 640, and the pressing portion 630 extends out of the bottom plate. The pivot joint 620 is provided with a mounting hole and is rotatably mounted on the first mounting shaft through the mounting hole. The other end of the torsion spring is connected with the bottom plate in an abutting mode.

The top end of the locking portion 640 is disposed at an included angle and has a first blocking surface 641 and a second blocking surface 642. A plurality of latch teeth 21 are uniformly distributed on the rotating disc 20, and the latch teeth 21 are arranged in a fan shape and are provided with a first matching surface 22 and a second matching surface 23. When the rotating disc 21 is locked, the first blocking surface 641 is blocked by the first matching surface 22, or the second blocking surface 642 is blocked by the second matching surface 23, so that the rotating disc 21 cannot rotate. When the rotating disc is released, the pivoting part 640 extends out of the space between the clamping teeth 21, and the rotating disc 20 can rotate in the forward direction to release the rope body and can rotate to retract and wind the rope body. When the pivoting portion 640 partially extends between the latches 21, if the rotating disc 20 rotates reversely, the second engaging surface pushes 23 the second blocking surface 642, so that the pivoting portion 640 completely extends between the latches 21, thereby enabling the rotating disc 20 to rotate normally. However, if the rotary disk 20 is rotated in the forward direction, the first engagement surface pushes 22 the first blocking surface 61, and the damping of the lock member by the torsion spring cannot be overcome, so that the first rotary disk 21 cannot be rotated in the forward direction.

The rotary table comprises a rotary table shaft arranged on the shell and clamping tooth discs arranged at two ends of the rotary table shaft, and the clamping teeth are arranged on the clamping tooth discs. A volute spiral spring (not shown) is arranged on the turntable shaft. When the rotary disc is released, external force overcomes the damping of the volute spiral spring to the rotary disc, the rotary disc is driven to rotate in the forward direction, the traction rope is released, or the volute spiral spring pushes the rotary disc to rotate in the reverse direction, and the traction rope is wound.

The foregoing is a more detailed description of the present invention, taken in conjunction with the specific preferred embodiments thereof, and it is not intended that the invention be limited to the specific embodiments shown and described. To the utility model belongs to the technical field of the ordinary technical personnel, do not deviate from the utility model discloses under the prerequisite of design, its framework form can be nimble changeable, can derive series of products.
