[0024] The technical scheme of the utility model will be described below in connection with the drawings in a clear and complete manner. Obviously, the described embodiments are only some of the embodiments of the utility model, not all of the embodiments.

[0025] Reference Figures 1 to 5 , an easily detachable puller and upper stop structure, including chain belt 10 and the puller 20 for making chain belt 10 chain tooth engagement or separation, the puller 20 includes upper boat board 21, lower boat board 22 and the support column 23 connected between upper boat board 21 and lower boat board 22, and the opposite extension of upper boat board 21 and lower boat board 22 respectively with the outline of its contour is provided with surrounding edge 24, and the slot 25 for chain belt 10 to pass through is arranged between the two surrounding edges 24, and the top end of chain belt 10 is provided with the upper stop 30 for preventing the puller 20 from falling out, and the upper stop 30 is generally oval in whole, including abutment end 31 and stop end 32, wherein the stop end 32 is fixedly connected with chain belt 10, the abutment end 31 extends to the outside of chain belt 10, and the two sides of the upper stop 30 are provided with arc guiding edge 33, and the bottom of the stop end 32 is concave inward and provided with stop recess 34 for preventing the puller 20 from falling out.

[0026] In the embodiment, the upper stop 30 has a first state and a second state, when the puller 20 is pulled to the top end of chain belt 10, at this time, the upper stop 30 is in the first state, that is, the stop recess 34 abuts against the end of surrounding edge 24, so that the puller 20 can be limited, and the puller 20 is prevented from falling out;When it is needed to detach the puller 20, the user folds chain belt 10 to make the upper stop 30 in the state close to vertical, and the puller 20 is detached from chain belt 10. Figure 5In the second state, the two arc-shaped guiding edges 33 of the upper stop piece 30 abut against the inner side walls of the two surrounding edges 24 and the support 23, and in this state, the two arc-shaped guiding edges 33 of the upper stop piece 30 can reduce the friction with the puller 20, improve the smoothness during operation, and the user only needs to pull down the chain belt 10 or pull up the puller 20 to take out the puller 20, which is more convenient for replacing and disassembling the puller 20, and the puller 20 is not easy to be taken out during use.

[0027] With reference to Figures 1 to 5 The thickness of the upper stop piece 30 is smaller than the distance between the upper deck 21 and the lower deck 22, so that the upper stop piece 30 can smoothly move in the puller 20 when the puller 20 is taken out; the thickness of the stop end 32 is greater than the width of the slot 25, so that the upper stop piece 30 can more stably limit the puller 20 in the first state; the top surface of the upper deck 21 is provided with a pull nose 211, and the pull nose 211 is provided with a pull piece 212 for driving the puller 20 to move on the chain belt 10, and in the embodiment, the material of the upper stop piece 30 and the puller 20 can be any one of metal, resin or nylon.

[0028] It should be noted that since the upper stop structure in the present scheme can conveniently take out the puller 20, the user can match different colors or shapes of the puller 20 according to his own preferences and clothing styles during use, in addition, a plurality of special-shaped holes can be formed on the upper deck 21 and / or the lower deck 22 of the puller 20, which can not only improve the design sense of the puller 20, but also meet the personalized needs of the user.

[0029] The above is only a specific embodiment of the present application, but the design concept of the present application is not limited thereto, and any non-substantial change to the present application using this concept shall be deemed as an infringement of the protection scope of the present application.
