Description

TECHNICAL FIELD

[0001] The utility model relates to a core digging knife technical field, concretely relates to a ring core digging knife. BACKGROUND

[0002] The fruit core digging knife on the market has old function, dull blade, single size of cutter, poor applicability to fruits with different shapes and sizes, and low core removing efficiency; fruit pulp is wasted seriously and not beautiful during core removing, especially for the fruits such as peaches and pears with hard fruit core, the operation is difficult, and the hands of workers are prone to fatigue.

[0003] In addition, most of the core digging knives on the market have integral structure of the cutter body and the handle, the cutter body and the handle are fixedly connected, when the cutter body is blunt or damaged, the cutter body cannot be replaced alone, and the cutter body and the handle can only be discarded together, which is very wasteful. UTILITY MODEL CONTENTS

[0004] The utility model aims at providing a ring core digging knife, blade edges are arranged on both sides of the cutter head, the utility model is more convenient and labor-saving, and has longer service life; meanwhile, the cutter body and the handle are designed as detachable connection structure, the cutter body is convenient to replace, and cost is saved.

[0005] The utility model discloses a handle, the top of handle is installed with detachable cutter body, the cutter body is that a long strip shaped cutter plate is formed into the cutter head of top circle shape and two cutter legs formed by two end portions of cutter plate on the lower side of cutter head, and the blade edge is arranged on the edge of cutter plate on at least one end of the cutter head of circle shape, the top of handle is equipped with the installation cavity for two cutter legs, the upper end of handle is installed with the expansion pin inserted into the installation cavity and passing through between two cutter legs, and the expansion pin is tightly pressed on the left and right cavity surfaces of installation cavity respectively.

[0006] After the above structure is adopted, the cutter body is detachably connected on the handle through the expansion pin, when the cutter head is damaged or needs to be replaced, the cutter body part can be easily replaced by taking down the expansion pin, and the handle can still be used, which saves production materials and reduces the economic expenditure of the user, and meanwhile, installation and dismounting are convenient.

[0007] Preferably, the edges of the two end cutter plates of the cutter head of circle shape are both provided with the blade edge.

[0008] Preferably, the lower portions of the two cutter legs are fixedly connected together through the fixed pin.

[0009] Preferably, the outer side wall of handle is provided with a plurality of anti-skid ribs extending along the length direction of handle.

[0010] Preferably, the cutter plate of one side of the cutter head of circle shape protrudes outward to the cutter head main body and forms the lug.

[0011] Preferably, the handle has an internal receiving cavity with an opening at its lower part, and a bottom cover is screwed onto the lower opening of the receiving cavity; a conical ejector pin is placed inside the receiving cavity.

[0012] In summary, this utility model has the following beneficial effects:

[0013] 1. The blade body is detachably connected to the blade holder via a tensioning pin. When the blade tip is damaged or needs to be replaced, the tensioning pin can be removed to easily replace the blade body. The blade holder can still be used, which saves production materials and reduces the economic expenditure of users. At the same time, it is easy to install and disassemble.

[0014] 2. Both ends of the blade are equipped with cutting edges, allowing for easy cutting from both sides when removing fruit pits, thus extending the lifespan of a single blade. Additionally, the double-edged blades reduce friction between the blade and the fruit pulp, making it easier to remove the pit.

[0015] 3. The blade on one side of the circular blade protrudes outward to the main body of the blade and forms a lug. The lug is also a double-edged structure. The lug can hook out the fruit pit fragments and wood fibers remaining in the pulp, making the pitting process cleaner. Attached Figure Description

[0023] The utility model will be further described below with reference to the drawings.

[0024] The orientation referred to in the specification is the orientation of the ring-shaped core removing knife in normal operation, and is not limited to the orientation during storage and transportation.

[0025] Embodiment one:

[0026] As Figures 1 to 4 As shown in the drawings, a ring-shaped core removing knife comprises a handle 1, and a detachable blade body 2 is mounted at the top end of the handle 1; the blade body 2 is formed by coiling a long strip-shaped blade plate into a ring-shaped blade head 201 at the top end and two blade legs 202 formed by the two end portions of the blade plate at the lower side of the blade head 201, the lower portions of the two blade legs 202 are fixedly connected together through a fixing pin 4, and a blade edge 203 is formed on the edge of the blade plate at at least one end of the ring-shaped blade head 201; the top portion of the handle 1 is provided with a mounting cavity 101 for inserting the two blade legs 202, the mounting cavity 101 is a tapered cavity with an increasing outer diameter from the top of the handle 1 downwards; the upper end portion of the handle 1 is provided with a tensioning pin 3 inserted into the mounting cavity 101 and passing through the space between the two blade legs 202, the tensioning pin 3 tightly abuts against the two blade legs 202 on the left and right cavity surfaces of the mounting cavity 101 respectively, so as to tightly clamp the blade body 2; when the blade head 201 is damaged or needs to be replaced, the tensioning pin 3 can be removed to easily replace the blade body part, and the handle 1 can still be used, thereby saving production materials and reducing the economic expenditure of the user.
