[0028] Referring to the drawings, a specific structure of the utility model is reflected. The Gatling firework with reduced standby length comprises a plurality of bead products 1, an outer cylinder 2, a handle body 3, a core pipe 4, a protective sleeve 5, the plurality of bead products 1 are fixedly connected with the outer wall of the core pipe 4 to form a combined body, and the protective sleeve 5 protects the top end of the combined body in standby. The bottom end of the combined body is fixedly installed with a sliding seat 6, the sliding seat 6 has a middle hole 601 arranged corresponding to the inner cavity of the core pipe 4, and the combined body and the sliding seat 6 thereof are slidingly sleeved in the outer cylinder 2; the top end of the outer cylinder 2 is fixedly installed with an upper connecting sleeve 7, and the upper connecting sleeve 7 is connected with the sliding seat 6 through a clamping mechanism.

[0029] In the example, the clamping mechanism comprises a limiting step 701 arranged on the inner wall of the upper connecting sleeve 7; and further comprises an elastic clamping tongue 602 arranged on the upper end of the outer wall of the sliding seat 6; when the upper end of the outer wall of the sliding seat 6 abuts against the limiting step 701, the elastic clamping tongue 602 is clamped at the top end of the upper connecting sleeve 7. The use convenience in the conversion operation between the standby state and the working state can be improved, the hand feeling is clear, the operation is light and accurate, and the components are closely matched.

[0030] In the example, the side wall of the upper connecting sleeve 7 and the sliding seat 6 is provided with a plurality of arc surfaces arranged in a ring, and the arc surfaces are arranged corresponding to the side surface outer contour of the combined body. The arrangement of the arc surfaces makes the combined body, the upper connecting sleeve 7 and the sliding seat 6 closely matched, avoids the circumferential rotation between the three, and makes the sliding orderly. In the example, the elastic clamping tongue 602 is arranged at the connecting part of the two arc surfaces. The working reliability of clamping is improved.

[0031] The bottom end of the outer cylinder 2 is fixedly installed with a lower connecting sleeve 8, the connecting part 301 of the handle body 3 is threadedly connected with the inner cavity of the lower connecting sleeve 8, and the inner cavity and the middle hole 601 of the core pipe 4 allow the handle body 3 to be inserted.

[0032] Standby state: the combination and its sliding seat 6 along the inner cavity of the outer cylinder 2 to the lower connecting sleeve 8 abutment, so as to make full use of the inner cavity space of the outer cylinder 2; the handle body 3 passes through the inner cavity and the middle hole 601 of the lower connecting sleeve 8 and is inserted into the inner cavity of the core tube 4, which can fully utilize the inner cavity space of the core tube 4 to store the handle body 3.

[0033] Working state: the combination and its sliding seat 6 along the inner cavity of the outer cylinder 2 to the upper connecting sleeve 7 through the clamping mechanism connection can be achieved fixed; pull out the handle body 3 and rotate, so that its connecting part 301 and the inner cavity of the lower connecting sleeve 8 are screw connected. It can be ignited. The sliding seat 6 and the handle body 3 maintain a sufficient safety distance in the working state, ensuring the personal safety of the igniter.

[0034] As can be seen from the above, the beneficial effects of the present application are that, through the above structure, in standby state, the length of the product in standby state is effectively shortened from the upper and lower directions based on the space superposition mode, and the length ratio of standby state / working state is effectively reduced. In the example, the length ratio of standby state / working state of the product reaches 1:2 or more, greatly reducing the product packaging length and greatly reducing the packaging storage and transportation cost. Moreover, the above structure also has the advantages of convenient operation and use in the conversion of standby state / working state.

[0035] The above disclosed embodiments of the present application are only used to help explain the present application. The embodiments do not describe all the details, nor limit the present application to the specific implementation described. Obviously, according to the content of the present application, many modifications and changes can be made.
