DETAILED DESCRIPTION

[0025] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0026] Please refer to Figure 1 and Figure 2 , the scissors 100 includes a first blade 10, a second blade 30, a handle 50 and a fastener 70. The first blade 10 and the second blade 30 are arranged in an upper-lower overlapping manner, and the tail ends of the first blade 10 and the second blade 30 are respectively connected with a handle 50. The fastener 70 penetrates through the first blade 10 and the second blade 30, so that the first blade 10 and the second blade 30 are connected together. The first blade 10 and the second blade 30 can rotate around the fastener 70, so that the scissors 100 can switch between a closed state and an open state.

[0027] Please refer to Figures 3-5 , the first blade 10 includes a first body 11, a first blade edge 13 and a first tail end 15. The first body 11 is in a block structure, and a first pin hole 112 is formed through the first body 11. The first blade edge 13 is in a strip structure, which is formed by protruding and extending from one end of the first body 11, and is used for cutting the rhizome of plants. The first tail end 15 is formed by protruding and extending from the other end of the first body 11, and is used for installing the handle 50. The first blade edge 13 and the first tail end 15 are divided by the first pin hole 112, that is, the first pin hole 112 is located between the first blade edge 13 and the first tail end 15.

[0028] The first pin hole 112 is a plum blossom hole, and an abutting portion 1121 is formed inwardly from the inner side wall of the first pin hole 112 toward the center of the first pin hole 112. The middle portion of the abutting portion 1121 protrudes relative to the two ends of the abutting portion 1121, and is substantially arc-shaped, U-shaped, or arch bridge-shaped, etc. It can be understood that the number of the abutting portion 1121 can be one, two, or more, and is preferably three or more. The plurality of abutting portions 1121 can abut against the fastener 70 from multiple directions, thereby preventing the fastener 70 from shaking during the opening and closing of the scissors 100. In the present embodiment, the number of the abutting portion 1121 is four, and each of the four abutting portions 1121 protrudes from the upper, lower, left, and right directions of the first pin hole 112, and the two adjacent abutting portions 1121 are arranged at substantially perpendicular positions, and the two abutting portions 1121 are arranged opposite to each other. In the present embodiment, the surface of each abutting portion 1121 close to the center of the first pin hole 112 is curved, and the top ends of the curved surfaces of the four abutting portions 1121 are connected together with the fastener 70. A gap is formed between the two adjacent abutting portions 1121, and the gap is used to discharge the juice of the plant. The top surface of each abutting portion 1121 is formed with a guide surface 1125 that gradually inclines from the top surface of the first body 11 toward the center of the first pin hole 112. The juice of the plant enters the first pin hole 112 along the guide surface 1125, and is discharged through the gap, so as to prevent the juice of the plant from remaining in the first pin hole 112.

[0029] The second blade 30 has substantially the same structure as the first blade 10. The second blade 30 includes a second body 31, a second blade edge 33, and a second tail end 35. The second body 31 is provided with a second pin hole 312. The second blade edge 33 is in a long strip structure, and is used to cut the rhizome of the plant by cooperating with the first blade edge 13. The second tail end 35 protrudes from the other end of the first body 31, and is used to install the handle 50. The second blade edge 33 and the second tail end 35 are divided by the second pin hole 312, i.e., the second pin hole 312 is located between the second blade edge 33 and the second tail end 35. The second pin hole 312 is a circular hole. It can be understood that the second pin hole 312 can also be a plum blossom hole or a polygonal hole.

[0030] It can be understood that the number of the first blade 10 and the second blade 30 is not limited to one.

[0031] Please refer to Figure 6 and Figure 7 The fastener 70 includes a pin 71 and a pin pad 73. The pin pad 73 is placed on the body 11 of the first blade 10, and the pin 71 passes through the pin pad 73, the first pin hole 112, and the second pin hole 312 in sequence, so that the second blade 30 and the first blade 10 are connected together.

[0032] The pin 71 includes a head 711, a column 713 connected to the head 711. The head 711 is a flat cylinder, and the column 713 is an elongated cylinder. The diameter of the head 711 and the pin washer 73 is larger than the diameter of the column 713. The column 713 can be inserted and pass through the first pin hole 112 and the second pin hole 312, and is tangent to the middle of the abutting portion 1121 of the first pin hole 112 and the inner wall of the second pin hole 312. In this embodiment, the column 713 only contacts the top surface of the abutting portion 1121, and the two ends of the abutting portion 1121 do not contact the column 713, so that a gap is formed between the two ends of the abutting portion 1121 and the column 713, which corresponds to the through hole 1123. The four abutting portions 1121 can form at least four through holes 1123, which pass through the thickness direction of the first blade 10. Therefore, even in the case of accumulation of resin stains, foreign matter, high-viscosity grease, and adhering matter, the resin stains, foreign matter, high-viscosity grease, and adhering matter are discharged through the through hole 1123 to ensure that the fastener 70 will not stick to the inside of the first pin hole 112 and the second pin hole 312, so that easy opening and closing actions can be performed for a longer period of time. When the column 713 is inserted into the first pin hole 112 and the second pin hole 312, the first blade 10 limits the pin washer 73 and the head 711, so that the fastener 70 will not fall off the scissors 100.

[0033] Further, the first pin hole 112 in the plum blossom shape makes the area of the through hole 1123 formed between the first pin hole 112 and the fastener 70 larger, and is less likely to form a stack of adhering matter, and improves the cleaning ability of the scissors 100 by a larger water flow. The gap is formed at the connection between the two adjacent abutting portions 1121, and the gap is part of the through hole 1123.

[0034] The pin washer 73 is generally in the shape of a C, i.e., a circular ring-shaped washer with one opening 731.

[0035] The first blade 10 and the second blade 30 are arranged in an overlapping manner, i.e., the bottom surface of the first blade 10 is arranged in a spaced-apart manner with the top surface of the second blade 30, so that a gap 131 is formed between the first blade 10 and the second blade 30. The width of the gap 131 is generally 0.15-0.4 mm. When the gap 131 is 0.15-0.4 mm, the water flow can smoothly pass through the gap 131, and the opening and closing of the scissors 100 is smooth. In some embodiments, the width of the gap 131 can be other sizes, which is determined according to actual needs.

[0036] As Figure 7As shown, the opening 731 of the pin pad 73, the through hole 1123 of the first blade 10, and the gap 131 between the first blade 10 and the second blade 30 are in communication to form the flow channel 20. When the scissors 100 is cleaned, water flows along the opening 731, the through hole 1123, and the gap 131 in turn to the outside, so that the water flow flushes the adhering objects out of the flow channel 20 to prevent the adhering objects from remaining at the joint of the first blade 10 and the second blade 30.

[0037] Referring to Figure 1 and Figure 2 The middle part of the handle 50 is hollowed out to form a hollow 51. The hollow 51 is used for the hand to pass through to facilitate force. The tail end of the first tail end 15 and the second tail end 35 is respectively connected with a handle 50. The inner side walls of the two handles 50 opposite to each other protrude to form a limiting protrusion 53. When the handles 50 of the first tail end 15 and the second tail end 35 move synchronously toward the side away from the limiting protrusion 53, the first blade 13 and the second blade 33 simultaneously open toward the side away from the limiting protrusion 53. The opening between the first blade 13 and the second blade 33 becomes larger, and the scissors 100 is in an open state. When the handles 50 of the first tail end 15 and the second tail end 35 move synchronously toward the side close to the limiting protrusion 53, the first blade 13 and the second blade 33 simultaneously contract toward the side close to the limiting protrusion 53. The opening between the first blade 13 and the second blade 33 becomes smaller, and the first blade 13 and the second blade 33 overlap together, and the scissors 100 is in a closed state. In the closed state, the limiting protrusions 53 of the two handles abut against each other, so that the two limiting protrusions limit each other.

[0038] The scissors 100 of the embodiment forms the flow channel 20 for water flow through the opening 731 of the pin pad 73, the through hole 1123 between the fastener 70 and the pin hole 112, 312, and the gap 131 in communication with each other, and the adhering objects can flow out through the flow channel 20, thereby improving the ability to clean the adhering objects.

[0039] So far, the technical scheme of the utility model has been described in combination with the preferred embodiments shown in the drawings, but those skilled in the art can easily understand that the protection scope of the utility model is obviously not limited to these specific embodiments. Without deviating from the principles of the utility model, those skilled in the art can make equivalent changes or replacements to related technical features, and the technical schemes after these changes or replacements will all fall within the protection scope of the utility model.
