Detailed Description

The present invention will be further described with reference to the following examples.

Example one, a double blade type ring cutter. Taking a small section of steel pipe, cutting the upper part of the small section of steel pipe into a cutter body in the shape of the figure 1, wherein the upper part of the cutter body is a double-blade cutting edge, the lower part of the cutter body is tubular, and the lower end of the cutter body is provided with a plastic cutter sleeve. When the plastic cutting knife is used, the plastic knife sleeve is pressed by hands, the knife tip is downwards pointed to the plastic bottle mouth to be stabbed and rotated, the sealing piece can be cut, the plastic cutting knife is rotated by 90 degrees when half cutting is needed, and the plastic cutting knife is rotated by 180 degrees when full cutting is needed, so that the operation is completed.

Example two, single blade type ring cutter. Taking a small section of steel pipe, cutting the upper part into a cutter body in the shape of the figure 1-1, and constructing, using and operating the rest parts as the first embodiment.

The two embodiments described above have been able to cut the flaps of plastic bottle necks, but do not facilitate the application of pressure.

In the third embodiment, a girdling knife of the transverse compression bar is added. For applying pressure conveniently, as shown in fig. 3 and fig. 3-1, the transverse pressure rod is respectively arc-shaped and linear, a keyhole and a hanging ring are arranged on the transverse pressure rod, the transverse pressure rod is pressed when in use, and the rest parts are the same as the first embodiment.

After the three types of products are used, a blade protecting sleeve needs to be covered on the knife point and the blade, and the blade protecting sleeve is shown in figure 4. The cutting edge protecting sleeve is not connected with the whole product, namely the girdling knife, so that the knife tip is easy to accidentally injure a human body if the user forgets to cover the cutting edge protecting sleeve.

Example four, telescoping type cutter. In order to overcome the defects of the three products, the applicant develops a telescopic cutter, the method is to enlarge a cutter sleeve, the cutter sleeve and a cutter body are not fixedly welded, and the cutter body can reciprocate up and down in the cutter sleeve. In fig. 5-2, the lower end of the straight rod is welded on the circular sealing piece of the cutter body, the straight rod penetrates through the circular hole of the cutter sleeve, the upper end of the straight rod is connected with the middle point of the transverse pressure rod, the lower end of the spring is fixedly connected on the circular hole of the cutter sleeve, the upper end of the spring is connected with the middle point of the transverse pressure rod, the spring wraps the straight rod, the transverse pressure rod is provided with a hanging hole and a key ring, and as shown in fig. 5, in a static state, the cutter sleeve wraps the cutter body, and the cutter body is not exposed in the cutter sleeve. When the cutter is used, the finger of the handle extends into the spoon ring, the opening end of the cutter sleeve is aligned with the plastic bottle opening, the palm presses the transverse compression rod, the blade of the cutter point is exposed out of the opening end of the cutter sleeve, the cutter is rotated by 90 degrees when half cutting is needed, the cutter is rotated by 180 degrees when full cutting is needed, the operation is finished, then the hand is released, the transverse compression rod returns upwards under the action of the resilience force of the spring, and the cutter body also automatically retracts into the cutter sleeve from the opening end, see fig. 5. The product is hung on the fingers of a person through the spoon ring, so that the user naturally holds the knife sleeve at the moment.

The above embodiments are for letting the user understand the technical features of the present invention, not the protection scope of the present invention, all the similar products that do not make simple deformation through creative thinking still belong to the protection scope of the present invention.
