In this structure, the reel 2 and the housing 1 are relatively fixed by the plastic buckle 9 and the locking piece 4, so as to avoid accidental winding of the pipeline into the housing 1 during use. The plastic buckle 9 is a common part on the market and can be purchased directly, which is convenient for assembly and production. In addition, this structure reduces speed through the reduction gear set 3, reduces the speed of the gear connected with the locking piece 4, and reduces the friction and collision during the matching process of the locking piece 4 and the reduction gear set 3, which is beneficial to prolonging the service life of the locking piece 4 and the reduction gear set 3. The gear transmission is relatively accurate, compact, low noise, reliable operation and long service life.

[0038] In this embodiment, a reset spring 43 is arranged on the housing 1. The reset spring 43 drives the locking member 4 to reset and disengage the locking member 4 from the reduction gear set 3. The setting of the reset spring 43 prevents the locking member 4 from moving freely on the housing 1, and avoids accidental connection between the locking member 4 and the reduction gear set 3 during use, which is convenient for users.
