Description

A pure water barrel cover cutter

technical field

The invention relates to the field of cutters, in particular to a pure water bucket lid cutter.

Background technique

Due to concerns about the quality of tap water and the unsatisfactory sanitation of water dispensers, people usually buy bottled pure water + hand pump to solve the problem. But the bottled pure water cover is very firm and not easy to remove. In order to solve this problem, a cutter with simple structure, reliable performance, and the ability to conveniently cut the lid of barreled purified water is needed, and this solution comes out of it.

Contents of the invention

Aiming at the defects of the background technology, the present invention proposes a pure water bucket cover cutter, which has a simple structure and is convenient to use, and well solves the problem that people remove the cover of the pure water bucket.

In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:

A pure water bucket cover cutter, including a handle, a guide column, a return spring, a central fixed column, a cutting knife and a shell, the shell is cylindrical, and has a through hole that penetrates up and down, and the inner diameter of the through hole is the same as the outer diameter of the pure water bucket cover. diameter, and the top of the shell is provided with a top cover, and the handle is set on the top cover; the central fixing column is located in the through hole of the shell, and its top is fixed to the lower end of the return spring, and the other end of the return spring is connected to the top of the handle ; On, the guide column is fixed on the inner wall of the through hole of the shell, and the cutting knife is located on the guide column.

As a further optimization solution of the pure water barrel lid cutter of the present invention, the materials of the central fixing column and the guiding column are rigid materials.

As a further optimization solution of the pure water bucket lid cutter of the present invention, the inner diameter of the through hole of the casing gradually increases from the fixed position of the cutting knife to the bottom of the casing.

As a further optimization scheme of the pure water barrel lid cutter of the present invention, the cutting knives correspond to the guide columns one by one, and the total number is greater than or equal to 3, which are distributed on the inner wall of the through hole of the casing and are located on the same horizontal plane.

As a further optimization solution of the pure water barrel lid cutter of the present invention, the diameter of the central fixing column decreases gradually from top to bottom.

the

Compared with the prior art, the present invention adopts the above technical scheme and has the following technical effects:

First, it has two structures of central fixing column and guiding column to ensure that the pure water bucket cover cutter will not cut crookedly;

Second, the structure is simple and easy to use;

Third, the return spring is used to prevent the pure water bucket lid cutter from being stuck on the pure water bucket lid and cannot be pulled out.

Detailed ways

Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:

The invention provides a pure water bucket lid cutter, the structure of which is shown in Figure 1, including a handle 1, a guide column 2, a return spring 3, a central fixed column 4, a cutting knife 5, a casing 6, the casing 6 is cylindrical, and It has a through hole that penetrates up and down, the inner diameter of the through hole is compatible with the outer diameter of the pure water bucket cover, and the top of the shell is provided with a top cover; the handle 1 is arranged on the top cover; In the hole, its top is fixed with the lower end of back-moving spring 3, and the other end of back-moving spring 3 is connected to the top of handle 1;

The inner diameter of the through hole of the shell 6 gradually increases from the fixed position of the cutting knife to the bottom of the shell, so that it is more labor-saving when cutting, and the diameter of the central fixed column 4 gradually decreases from top to bottom. When cutting, the fixation is more secure. Each guide column 2 has a cutting knife 5 scattered on the inner wall of the shell 6. When cutting, it can be guaranteed that the cutting will not be biased, causing unnecessary damage to the bucket. The guide column 2 And central fixed post 4 adopts rigid material to make.

The user places the pure water bucket cover cutter on the top of the pure water bucket cover, and the central fixing column 4 is aligned with the center hole of the pure water bucket cover, and the pure water bucket cover cutter moves vertically downward under the guidance of the central fixing column 4; then the guide column 2 also starts to work, so that the cutter will not cut the mouth of the pure water bucket due to cutting deviation, the distance that the cutting knife stretches out is just equal to the thickness of the pure water bucket cover, because the cutter is symmetrically distributed 4 cutting knives 5, along with The downward movement of the cutter cuts 4 incisions on the side of the pure water bucket lid. After the cutter reaches the bottom, the user stops using force, and the pure water bucket lid cutter is separated from the pure water bucket lid under the action of the return spring 3 to prevent jamming. Immediately afterwards, the phenomenon that the cutter cannot be pulled out occurs, and then the user holds the handle 1 to pull out the pure water bucket lid cutter to complete the cutting action. Since the side of the pure water bucket cover is cut with 4 slits, the user will easily remove the clean water bucket cover.

The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and can also be made without departing from the gist of the present invention within the scope of knowledge possessed by those of ordinary skill in the art. Variations.
