[0004] In order to solve the above technical problems, the utility model provides a kitchen knife with a protective function.
[0005] The utility model is implemented by the following technical solution: a kitchen knife with a protective function, comprising a handle, the top of the inner wall of the handle is fixedly connected to a support plate, the inside of the handle is fixedly connected to a connecting column, the outer wall of the connecting column is rotatably connected to a protective block, the bottom of the protective block is provided with an avoidance groove, the inner wall of the protective block is provided with a card slot, the outer wall of the card slot is in contact with a pin rod, the pin rod is slidably connected to the inside of the handle, the pin rod is slidably connected to the inside of the support plate, one end of the pin rod close to the card slot is fixedly connected to a limiting plate, the outer wall of the pin rod is in contact with a spring, and the end of the pin rod away from the limiting plate is fixedly connected to a handle.
[0006] Through the above technical solution, the handle is pulled to drive the pin rod to move, and the pin rod slides inside the knife handle. At the same time, the pin rod slides inside the support plate. The support plate can provide a guide for the pin rod, so that the pin rod is out of the slot. The pin rod drives the limit plate to move, and the limit plate contacts the spring, so that the spring is compressed, so that the protective block can rotate. When the protective block rotates in a circle with the connecting column, it drives the stainless steel knife to rotate. An avoidance groove is opened on the inner wall of the protective block. The avoidance groove can avoid the pin rod when the protective block rotates. When the stainless steel knife rotates to the inside of the knife handle, the stainless steel knife is protected, thereby protecting the user's physical safety and preventing the stainless steel knife from causing harm to the user.
[0007] As a further improvement of the above solution, a stainless steel knife is fixedly connected to the back of the protective block, and a snap-in hole is opened inside the stainless steel knife. There are two snap-in holes, and the two snap-in holes are symmetrically arranged around the center of the stainless steel knife.
[0008] As a further improvement of the above solution, a gripping groove is provided at the bottom of the handle, a hanging ring is fixedly connected to the back of the handle, and a plurality of gripping grooves are provided, and the plurality of gripping grooves are evenly arranged on the surface of the handle.
[0009] As a further improvement of the above solution, a fixing plate is fixedly connected to the top of the inner wall of the handle, and two fixing plates are provided, and the two fixing plates are symmetrically arranged around the center of the handle.
[0010] Through the above technical solution, a grip groove is opened at the bottom of the knife handle, which can make users use it more comfortable. A hanging ring is fixed on the outer wall of the knife handle, and the stainless steel knife can be hung in a high position to prevent children from touching it and protect the safety of children.
[0011] As a further improvement to the above solution, a connecting rod is slidably connected inside the fixed plate, and the connecting rod is slidably connected inside the handle. A spring 1 is provided at one end of the connecting rod close to the fixed plate.
[0012] As a further improvement of the above solution, one end of the connecting rod close to the spring one is fixedly connected to the limiting plate one, and one end of the connecting rod away from the limiting plate one is fixedly connected to the fixing plate one.
[0013] As a further improvement of the above solution, two limit plates are provided, and the two limit plates are symmetrically arranged around the center of the knife handle; two springs are provided, and the two springs are symmetrically arranged around the center of the knife handle.
[0014] Through the above technical solution, when the stainless steel knife rotates into the inside of the knife handle, the connecting rod drives the fixed plate to move. While the connecting rod slides inside the knife handle, it also slides inside the fixed plate. At this time, the spring pushes the limit plate through the elastic force, and the limit plate drives the connecting rod to move, thereby clamping the connecting rod in the clamping hole, thereby preventing the stainless steel knife from falling after being retracted into the inside of the knife handle, thereby fixing the stainless steel knife and protecting the user's safety.
[0015] Compared with the prior art, the beneficial effects of the present invention are:
[0016] The utility model drives the pin rod to move by pulling the handle, and the pin rod slides inside the knife handle. At the same time, the pin rod slides inside the support plate. The support plate can provide a guide for the pin rod, so that the pin rod is separated from the inside of the slot. The pin rod drives the limit plate to move. The limit plate contacts the spring, so that the spring is compressed, so that the protective block can rotate. When the protective block rotates in a circle with the connecting column, it drives the stainless steel knife to rotate. An avoidance groove is opened on the inner wall of the protective block. The avoidance groove can avoid the pin rod when the protective block rotates. When the stainless steel knife rotates to the inside of the knife handle, the stainless steel knife is protected, thereby protecting the user's physical safety and preventing the stainless steel knife from causing harm to the user.
[0017] The utility model realizes that when the stainless steel knife is rotated into the handle, the connecting rod drives the fixing plate to move. The connecting rod slides inside the handle and also slides inside the fixing plate. At this time, the spring pushes the limiting plate through the elastic force, and the limiting plate drives the connecting rod to move, thereby clamping the connecting rod in the clamping hole, thereby preventing the stainless steel knife from falling after being retracted into the handle, thereby fixing the stainless steel knife and protecting the user.
