[0007] Preferably, the control mechanism includes a rotating shaft fixed to a friction wheel. A sleeve is rotatably mounted on the inner wall of the fixed plate. A spiral spring is fixed to the surface of the sleeve, with the end of the spiral spring away from the sleeve fixed to the inner wall of the fixed plate. A pull rope is wound and fixed to the surface of the sleeve, passing through the middle and tail cylinders. A pawl is provided on the surface of the rotating shaft, and a ratchet is provided on the inner side of the sleeve. Pulling the pull rope controls the rotation of the sleeve. At this time, the ratchet on the inner side of the sleeve can engage with the pawl, thereby driving the friction wheel to rotate through the rotating shaft. When the pull rope is released, the sleeve can rotate in the opposite direction under the action of the spiral spring. At this time, the ratchet on the inner side of the sleeve cannot engage with the pawl, thus preventing the friction wheel from rotating. This avoids unsuccessful ignition on the first attempt and allows for a second ignition operation.

[0008] Preferably, the inner side of the head tube is fixed with a guide cavity, in which a ribbon is placed and ignited by gunpowder. The inner side of the tail tube is provided with a placement cavity, which can be used to place gunpowder.

[0009] Preferably, the tail cylinder is inserted into the middle cylinder, and the middle cylinder is threadedly connected to the head cylinder.

[0010] Compared with the prior art, this utility model provides a handheld, safe, and compact pull-tab structure with the following advantages:

[0011] 1. This handheld, safe, pull-action cannon features a driven mechanism. When gunpowder needs to be added to the middle cylinder, the middle cylinder is separated from the head cylinder. The L-shaped abutment rod is no longer pressed by the head cylinder, thus preventing it from exerting a pushing force on the support block. Under the action of the spring, the support block moves the flint away from the friction wheel, ensuring that the flint does not contact the friction wheel. This guarantees safety during gunpowder loading, prevents accidental ignition of the gunpowder and avoids potential danger, and allows for reuse, thus avoiding resource waste.

[0012] 2. This handheld, safe pull-string igniter features a control mechanism that allows the sleeve to rotate by pulling a cord. At this time, the ratchet inside the sleeve engages with the pawl, causing the friction wheel to rotate via the shaft. When the cord is released, the sleeve rotates in the opposite direction under the action of the spiral spring. In this case, the ratchet inside the sleeve cannot engage with the pawl, thus preventing the friction wheel from rotating. This avoids unsuccessful ignition on the first attempt and allows for a second ignition operation. Attached Figure Description
