[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] As attached Figure 1-5As shown, the utility model provides a safety hand stop for a stamping machine, including a gear 1, a rack 2 is arranged on one side of the gear 1, a rack fixing plate 3 is arranged on the side of the rack 2 away from the gear 1, a rack connecting plate 4 is welded to one side of the rack fixing plate 3, an auxiliary fixing plate 5 is arranged on the rear side of one end of the rack connecting plate 4 away from the rack 2, two connecting rods 6 are fixedly installed between the auxiliary fixing plate 5 and the rack connecting plate 4, two synchronization rods 7 are welded on the front side of the gear 1, and the same protective rod 8 is arranged on the end of the two synchronization rods 7 away from the gear 1, a bearing 9 is fixedly installed inside the gear 1, a gear mounting plate 10 is arranged on the rear side of the gear 1, a gear shaft 11 is welded on the gear mounting plate 10, and a bushing 12 is fixedly installed on the front side of the gear 1 by screws.

[0020] The bearing 9 is sleeved on the gear shaft 11 , and the gear 1 is rotatably connected to the gear shaft 11 via the bearing 9 .

[0021] The rack fixing plate 3 is fixedly connected to the rack 2 by screws.

[0022] The protection rod 8 is fixedly connected to the ends of the two synchronization rods 7 by screws.

[0023] The gear 1 is meshed with the rack 2 .

[0024] The specific implementation method is as follows: when using the utility model, the auxiliary fixing plate 5 is fixedly installed on the body of the punching machine, and then the gear mounting plate 10 is fixedly installed on the slider that moves up and down when the punching machine is working. When the punching machine is running, the slider that moves up and down drives the gear 1 to move up and down, and the gear 1 is engaged with the rack 2. Therefore, during the movement, the gear 1 will rotate. The rotation of the gear 1 drives the protective rod 8 to rotate through the two synchronization rods 7. The protective rod 8 rotates. The rotation of the protective rod 8 can push away the hand placed between the upper and lower molds by mistake, avoiding personal injury accidents. This enables the utility model to avoid the operator from injuring his hands and arms when taking the workpiece during the stamping process, thereby avoiding work-related accidents, ensuring the personal safety of the operator, and having a high safety factor.
