Problems to be Solved by the Invention In the conventional food cutter safety device, the main body 2
It is necessary to perform operations to lock the container 3 and the container 3 and the lid 6, respectively, resulting in a problem of poor operability.

In other words, in order to prevent the container 3 and the lid 6 from coming off due to the impact or vibration of the food being cooked, the container 3 and the lid 6 had to be clamped twice.

The present invention solves the above-mentioned problems, and aims to provide a safety device for a food mixer that simplifies the operation of clamping containers and lids and allows safer use.

Means for Solving the Problems In order to achieve the above-mentioned objects, the present invention provides, as a first means for solving the problems, a clamp body that rotatably holds the lid of the container on the upper part of the side-standing case part of the main body. A safety device for a food mixer is provided in which a convex portion is provided on the upper surface of the lid, and a detecting portion of the lid is provided on the clamp body that engages with the convex portion and operates in conjunction with a safety switch.

In addition, as a means of solving the problem 2 above, a convex part is provided on the top surface of the lid of the container, and a lid detection part that engages with this convex part is provided on the rotating clamp body, so that the bracket clamp body is in a position where it presses the lid. The configuration is such that the detection section and the safety switch are interlocked only at certain times.

Function The first problem-solving means of the present invention works by holding the container lid with a rotatable clamp body, so that setting the container on the main body and setting the lid on the container can be done without clamping. Simply place it there. After this, by pressing the lid with the clamp body, the container and the lid can be clamped at once, and by providing a convex part on the lid, the clamp body can block the detection part of the lid that engages with this convex part, and can be used as a safety switch. Because they are interlocked, they cannot be operated unless the lid is held down by the clamp body. In addition, the second problem-solving means works by providing a convex portion on the lid of the container, and providing a lid detection portion that engages with the convex portion on the rotating clamp body, and raising the clamp body from the position where it presses the lid. When the time comes, the interlocking member between the detection part and the safety switch is released, and even if the detection part is pressed, the main body switch will not operate.
