Detailed Description

In order to make the technical solutions of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings and the detailed description.

As shown in fig. 1 and 3, the embodiment discloses a portable chestnut opener, which comprises an upper handle 1 and a lower handle 2, the ends of which are movably connected through a pin 7; the buckling surface of the upper handle 1 is welded with an upper container 3 with a downward opening; the buckling surface of the lower handle 2 is welded with a lower container 4 with an upward opening. The upper container 3 and the lower container 4 correspond to each other, and a cutting blade 5 is arranged in the upper container 3. The upper handle 1, the lower handle 2, the upper container 3 and the lower container 4 are made of 304-grade stainless steel.

In order to improve the cutting effect and the chestnut opening efficiency, the cutting blade 5 has a cross shape, and the cutting edge of the cutting blade 5 has a zigzag shape. In this embodiment, the cutting blade 5 is made of zirconia ceramics having better wear resistance. The serrated blade 5 and the upper holder 3 are connected by brazing.

Food-grade silica gel is used for wrapping the outer surface holding surfaces of the upper handle 1 and the lower handle 2, and the silica gel anti-slip layer covers the surface of the outer surface holding surfaces, so that the friction force between the Chinese chestnut mouth gag and the palm is increased, and the discomfort caused by using the mouth gag at the hand is reduced.

In order to improve the friction force between the chestnuts and the lower container 4, increase the fixation degree of the lower container 4 to the chestnuts and prevent the chestnuts from sliding out of the lower container 4 in the opening process, an anti-slip cushion layer 6 is bonded in the lower container 4.

In order to increase the resilience of the mouth gag and facilitate the taking out of the Chinese chestnuts and the putting in of the Chinese chestnuts without the mouth gag, the upper handle 1 and the lower handle 2 are provided with the reset spring 8 at the position close to the movable connection part, the upper end and the lower end of the reset spring 8 are respectively propped against the reserved positioning holes on the upper handle 1 and the lower handle 2 and are fixed with the corresponding reserved positioning holes.

In this embodiment, the buckling surfaces of the upper container 3 and the lower container 4 are both provided with the protection rings 10, and the protection rings 10 increase the fixation degree of the chestnuts and prevent the chestnuts from slipping out in the cutting and extruding opening process. The protective ring 10 is made of silica gel, and the material has elasticity and can increase the resilience of the mouth gag. The protective ring 10 is connected with the upper container 3 and the lower container 4 through a silica gel adhesive (such as KN-300A).

As shown in fig. 1 to 4, the upper handle 1 and the lower handle 2 are provided with a fixing buckle 9 on the fastening surface of the operation end. The fixed buckle 9 consists of a hook end 901 and a fixed end 902, and the hook end 901 is connected with the upper handle 1 through a small movable pin shaft, so that the hook end 901 can swing back and forth; the fixed end 902 is connected with the lower handle 2 through a welding method, the front and the side of the fixed end 902 are both open and have no baffle, the upper surface and the rear surface are respectively provided with a baffle, the upper baffle and the hook end 901 form a hook to prevent the mouth gag from bouncing off, and the baffle at the rear surface is used for preventing the hook end 901 from sliding out due to overlarge rotation angle; when the mouth gag is used, the hook end 901 is pulled forwards, so that the hook end 901 is separated from the fixed end 902 to be hooked, and when the mouth gag is not used, the hook end 901 is pulled backwards, so that the hook is hooked with the fixed end 902 to fix the mouth gag. The chinese chestnut mouth gag can be in the closed fixed state through fixed buckle 9 when idle state, prevents to lead to the mouth gag to open because of reset spring 8 kick-backs to with cutting blade 5 parcel when the mouth gag is in the closed state in holding the ware, improve the degree of safety.

The utility model discloses an operation process as follows:

during operation, firstly, the fixing buckle 9 at the tail end of the handle is opened to enable the Chinese chestnut opener to automatically spring open, then the Chinese chestnut is placed on the anti-skidding cushion layer 6 of the lower bearing device 4, the upper handle 1 and the lower handle 2 are combined, the operation ends of the upper handle 1 and the lower handle 2 are held by hands and are tightly held by force until cross sawtooth marks appear on the outer skin of the Chinese chestnut, the hands can be loosened, pressure is relieved, the upper handle 1 and the lower handle 2 can be opened due to the resilience force of the reset spring 8, so that the Chinese chestnut is loosened by the cutting blade 5, then the Chinese chestnut with the cut is taken out, finally, the fixing buckle 9 at the tail end of the handle is closed after the Chinese chestnut is used, the knife edge of the cutting blade 5 is completely sealed inside the bearing device, the safety of the Chinese chestnut opener is improved.

The above-mentioned embodiments are only intended to describe the preferred embodiments of the present invention, but not to limit the scope of the present invention, and those skilled in the art should also be able to make various modifications and improvements to the technical solution of the present invention without departing from the spirit of the present invention, and all such modifications and improvements are intended to fall within the scope of the present invention as defined in the appended claims.
