Referring to fig. 3, a first subtracting groove 123 is provided at one side of the connection block 12 near the draw-bar box side plate. The first material reducing groove 123 can reduce the material used for producing the connecting block 12, reduce the production cost of the inserting block 21 and save a lot of cost.

Referring to fig. 4, the second fastener 2 includes an insertion block 21 and a connection post 22. The connection post 22 is integrally provided at one side of the insertion block 21. The connecting post 22 is inserted into the pivot seat at a side far away from the insert block 21. Thereby fixing the second fastening member 2 to the draw-bar box side plate.

The insert block 21 is provided at a side thereof remote from the connection post 22 with a second insertion hole 211 into which the rotation shaft is inserted. One end of the rotation shaft may be inserted into the first insertion hole 121, and the other end of the rotation shaft may be inserted into the second insertion hole 211 to be fixed. The connecting plate 212 is arranged on one side, far away from the connecting column 22, of the inserting block 21, the connecting plate 212 is abutted to the plate surface of the draw-bar box side plate, two reinforcing plates 2121 are arranged on one side, far away from the draw-bar box side plate, of the connecting plate 212, and the reinforcing plates 2121 are gradually increased and inclined from one side, close to the draw-bar box side plate, to one side, far away from the draw-bar box side plate. By arranging two reinforcing plates 2121, the connection strength between the connecting plate 212 and the insert block 21 is enhanced, the risk of breakage of the connecting plate 212 due to stress is reduced, the service life of the connecting plate 212 is prolonged, and the fixation of the rotating shaft is more stable. In this embodiment, the insert 21, the connecting plate 212, and the two reinforcing plates 2121 are integrally injection-molded, and can be directly produced from one mold, which facilitates production.

Referring to fig. 5, a second subtracting groove 213 is opened at one side of the insert block 21 near the draw-bar box side plate. The second material reducing groove 213 can reduce the material used for producing the insert block 21, reduce the production cost of the insert block 21, and greatly save the cost.

The end of the connecting post 22 remote from the insert block 21 is provided with a guide surface 221. The guide surface 221 is provided to be gradually larger from a side away from the insert block 21 to a side close to the insert block 21. By providing the guide surface 221, the diameter of the insertion end of the connecting post 22 is smaller than that of the insertion hole of the rotating shaft seat, so that the connecting post 22 is convenient to insert, and the second fastener 2 is convenient to fix.

Referring to fig. 5, the connecting post 22 is provided with a plurality of abutment bars 222 on the peripheral side wall, and in this embodiment, the abutment bars 222 are preferably provided in four, and the four abutment bars 222 are uniformly spaced apart along the peripheral side wall of the connecting post 22. The abutting strip 222 can abut against the inner wall of the jack of the rotating shaft seat, so that friction between the connecting column 22 and the inner wall of the jack of the rotating shaft seat is increased, and the risk that the connecting column 22 rotates along the axis of the rotating shaft seat in the circumferential direction is reduced. Thereby making the fixation of the second fastener 2 more stable, and thus making the fixation of the rotation shaft more stable. In this embodiment, the abutment bar 222 and the connection post 22 are integrally injection molded, so that the connection post 22 and the abutment bar 222 are more convenient to produce.

The butt strip 222 is provided with the guide surface 2221 far away from one side of the inserted block 21, and the guide surface 2221 is gradually increased and inclined from one side far away from the inserted block 21 to one side close to the inserted block 21, and as the butt strip 222 needs to butt the inner wall of the jack of the rotating shaft seat, the connecting column 22 is difficult to insert, and the insertion end of the butt strip 222 is reduced through the guide surface 2221, so that the insertion of the connecting column 22 is facilitated, the fixation of the second fastener 2 is facilitated, and the fixation of the rotating shaft is further facilitated.

The implementation principle of the first embodiment is as follows: when the axis of rotation is required to be transported, insert the first embedding hole 121 of connecting block 12 with the one end of axis of rotation earlier, then detain connector link 11 on the draw-bar box curb plate, thereby fix first fastener 1, insert the second embedding hole 211 of inserting block 21 with the axis of rotation other end later, insert the jack of spliced pole 22 alignment pivot seat, thereby fix second fastener 2, first fastener 1 and second fastener 2 are all fixed in on the draw-bar box curb plate this moment, the axis of rotation is also fixed in on first fastener 1 and the second fastener 2, the risk that the axis of rotation rolls and drops has been reduced, the transportation of folding draw-bar box has been made things convenient for.

Example two

The second embodiment of the application discloses a draw-bar box side plate.

Referring to fig. 6, the fixing buckle includes a fixing buckle and a plate body 3 to which the fixing buckle is mounted.
