[0031] For example,Figs. 1 to 4 As shown, the embodiment of the present application provides a back door magnetic attraction anti-opening tool for locking and fixing the back door at the rear of the vehicle body. The tool comprises a first locking part 1, a second locking part 2 and a third locking part 3. The first locking part 1 is provided with a bayonet structure 12, which is clamped and connected with the stopper of the inner panel of the rear cover of the vehicle body. The second locking part 2 is provided with a bayonet pin 211, which is inserted with the positioning hole of the inner side of the inner panel. The first locking part 1 is connected with the second locking part 2. The third locking part 3 comprises a magnetic attraction unit and a hook unit, which are respectively connected with the second locking part 2. The magnetic attraction unit is magnetically connected with the inner side of the back door. One end of the hook unit passes through the window of the back door and is hooked on the outer side of the back door. The bayonet structure 12 of the first locking part 1 is clamped on the stopper of the inner panel. The magnetic attraction unit of the third locking part 3 is attracted on the inner side of the back door. The bayonet pin 211 of the second locking part 2 is inserted into the positioning hole of the inner side of the inner panel. Then, the hook unit of the third locking part 3 is pulled, so that the end of the hook unit passes through the window frame of the back door and is tightly hooked on the outer side of the back door. Thus, the back door and the inner panel of the rear cover of the vehicle are fixed and locked, which can ensure the stable connection between the back door and the inner panel and prevent the back door from falling off from the rear of the vehicle during the coating operation.
[0032] In some embodiments, the first locking part 1 comprises a first connecting rod 11 extending along the direction of the stopper at both ends. Each end of the first connecting rod 11 is provided with at least one bayonet structure 12. Each bayonet structure 12 has a clamping groove 121 with an opening facing the direction of the stopper at the corresponding position. The first connecting rod 11 is installed on the stopper of the inner panel through the bayonet structure 12 at the end, so as to clamp the stopper of the inner panel, which can realize the quick positioning, installation or disassembly of the whole tool and the inner panel.
[0033] In some embodiments, the bayonet structure 12 at each end of the first connecting rod 11 is one or more. When there are multiple bayonet structures 12, the multiple bayonet structures 12 are arranged at equal intervals along the length direction of the first connecting rod 11, so as to clamp along the direction of the clamping of the inner panel. However, considering the problem of narrow installation space, the bayonet structure 12 at each end of the first connecting rod 11 is one. Two bayonet structures 12 can stably clamp the stopper without occupying much installation space.
[0034] In some embodiments, the shape of the clamping groove of each bayonet structure 12 is determined by the shape of the stopper. For example, when the shape of the stopper is curved, the corresponding clamping groove 121 is designed as a curved groove. When the shape of the stopper is a straight plate, the corresponding clamping groove 121 is designed as a rectangular groove, so as to realize the accurate matching of the bayonet structure 12 and the stopper at the corresponding position.
[0035] In some embodiments, the opening length of the clamping groove 121 of each clamping structure 12 is slightly larger than the thickness of the corresponding position stopper, which facilitates the quick installation or disassembly of the clamping structure 12 relative to the stopper.
[0036] In some embodiments, the first locking part 1 further comprises a locking unit, which comprises a locking nut 13 and a locking bolt 14. The locking nut 13 is connected with the first connecting rod 11, and the port of the locking nut 13 is opposite to the inner side of the inner panel of the hood. The locking bolt 14 is threadedly connected with the locking nut 13, and when the locking bolt 14 is screwed into the inner side of the inner panel of the hood by a certain distance, the end of the locking bolt 14 abuts against the inner side of the inner panel of the hood. After the clamping structure 12 is positioned and installed on the corresponding position stopper, the locking bolt 14 in the locking unit is tightened until the end of the locking bolt 14 abuts against the inner side of the inner panel of the hood, thereby achieving the locking of the entire tooling and increasing the installation stability of the entire tooling.
[0037] In some embodiments, the number of locking units can be multiple in principle, for example, one locking unit is arranged at each end of the first connecting rod 11, which can achieve the locking and fixing of the entire tooling. Considering the narrow installation space, in fact, one locking unit is sufficient for use.

The rotating arm 15 can achieve the tightening or unscrewing of the locking bolt 14, and the locking operation can be achieved without the aid of external locking tools.
[0039] In some embodiments, the angle between the extending direction of the length of the rotating arm 15 and the axis of the locking bolt 14 is 90°.
[0040] In some embodiments, the second locking part 2 comprises a handle 21 and an elastic unit, the handle 21 has a clamping pin 211, and the elastic unit can produce elastic change and is connected with the handle 21 and the first connecting rod 11, respectively. After the positioning, installation and locking are sequentially achieved through the clamping structure 12 and the locking unit, the handle 21 is moved in the direction away from the first connecting rod 11 until the clamping pin 211 on the handle 21 is inserted into the positioning hole on the inner side of the inner panel of the hood, and at the same time, the elastic unit is deformed, thereby achieving the tensioning and fixing of the first connecting rod 11, forming multiple locking and fixing, and increasing the installation stability of the back door.
[0041] In some embodiments, the elastic unit comprises a helical rod 22 arranged along a set helical line, and a first end and a second end of the helical rod 22 are respectively connected with the handle 21 and the first connecting rod 11.
