[0034] Please refer to Figure 1-Figure 6The embodiment of the utility model provides a connection structure of a grinder, including a box body 111 and a cover body 120. The box body 111 includes a first threaded portion 1113, a rotating portion 1114 and a first chamber 1111, and a first member 1112 for grinding blades is arranged in the first chamber 1111. The cover body 120 is provided with a second threaded portion and a second member 121 matched with the first member 1112, the second threaded portion is threadedly matched with the first threaded portion 1113, the second threaded portion enters the rotating portion 1114 through the first threaded portion 1113, and the cover body 120 is rotatably connected to the box body 111 and detachable to cover the first chamber 1111. Exemplarily, when it is necessary to grind the blade, the user separates the cover body 120 from the box body 111, then puts the blade into the first chamber 1111, and then connects the cover body 120 to the box body 111 and rotates the cover body 120, so that the blade is ground or shredded under the cooperation of the first member 1112 and the second member 121. It should be noted that the first threaded portion 1113 is arranged at the front end of the box body 111, and the second threaded portion enters the rotating portion 1114 after passing through the first threaded portion 1113. At this time, the first threaded portion 1113 plays a role of limiting, so as to achieve the purpose of limiting the separation of the cover body 120 from the box body 111. The reason for this arrangement is that the application scenarios are different. The existing grinder is a separate product, and the user directly puts it in a bag or a pocket of clothes. Therefore, the box body 111 and the cover body 120 are usually connected by magnetic attraction, and the box body 111 and the cover body 120 will not be separated. However, the grinder of the present application is arranged on the drawstring buckle 100, which is usually hung on the user's pants. The user's hand or other external objects can easily touch the grinder. In this case, if the box body 111 and the cover body 120 are simply connected by magnetic attraction, the cover body 120 can easily be separated from the box body 111. Therefore, the present application adopts a position where the box body 111 and the cover body 120 are connected, with a threaded structure set at the front end portion and no threaded structure set at the rear end portion. In this way, when the cover body 120 is connected to the box body 111, it will not fall off easily, which meets the use requirements of the product of the present application.

[0035] Please refer to Figure 5 , Figure 6In a possible implementation, the extension width of the first threaded portion 1113 is recorded as D1, and the extension width of the rotating portion 1114 is recorded as D2, and the ratio D2 / D1 is in the range of [1,2]. Exemplarily, the extension width of the rotating portion 1114 needs to be greater than or equal to the extension width of the second threaded portion to ensure that the second threaded portion can allow the cover body 120 and the box body 111 to rotate relative to each other when cooperating with the rotating portion 1114. In this embodiment, the ratio D2 / D1 is 1.2. Of course, in specific applications, the ratio D2 / D1 is not limited to this. For example, as an alternative, the ratio D2 / D1 can also be 1, or 1.1, or 1.3, or 1.4, or 1.5, or 1.6, or 1.7, or 1.8, or 1.9, or 2.

[0036] Please refer to Figure 4 , Figure 5 , Figure 6 In a possible implementation, the connection structure of the grinder further includes a first magnetic member 130 and a second magnetic member 140 that cooperates with the first magnetic member 130, the first magnetic member 130 is disposed in the first chamber 1111, and the second magnetic member 140 is disposed on the cover 120.
