Description

Technical Field

[0001] This application relates to scissors, and more particularly to an adjustable tension scissors. Background Technology

[0002] The quality of hair clippers greatly affects a hairdresser's performance. Hair clippers require a very high degree of adjustment. Good hair clippers have almost no friction between the two blades, while ordinary hair clippers are usually directly connected by a bolt, making it difficult to adjust to the optimal state desired by the hairdresser. Utility Model Content

[0003] The purpose of this utility model is to provide an adjustable scissor. By setting an arc-shaped spring and an adjusting bolt, fine adjustment between the two blades can be achieved, so that there is almost no friction between the two blades.

[0004] To achieve the above objectives, the present invention provides the following technical solution.

[0005] This application discloses an adjustable scissors, including a first blade and a second blade hinged together. An arc-shaped spring is provided on the side of the first blade away from the second blade. The scissors also include a connecting bolt and an adjusting bolt. The connecting bolt passes through the arc-shaped spring and the first blade in sequence and is then threaded to the second blade. The adjusting bolt passes through the arc-shaped spring and is then threaded to the first blade.

[0006] Preferably, in the above-mentioned adjustable tension scissors, the head of the connecting bolt and the head of the adjusting bolt are respectively supported on the surface of the arc-shaped spring.

[0007] Preferably, in the above-mentioned adjustable tension scissors, the connecting bolt is located near the end of the arc-shaped spring, and the adjusting bolt is located near the middle of the arc-shaped spring.

[0008] Preferably, in the above-mentioned adjustable scissors, during use, the adjusting bolt adjusts the curvature of the arc-shaped spring piece, thereby adjusting the friction between the first blade and the second blade.

[0009] Preferably, in the above-mentioned adjustable scissors, the side of the first blade is recessed to form a spring groove for fitting and placing the arc-shaped spring piece.

[0010] Preferably, in the above-mentioned adjustable scissors, a gap is formed between the first blade and the second blade behind the hinge.

[0011] Preferably, in the above-mentioned adjustable tension scissors, a first bearing and a second bearing arranged side by side are sleeved on the outside of the connecting bolt, and the outside of the first bearing and the second bearing is sleeved on the support ring, which is formed on the arc-shaped spring.

[0012] Preferably, in the above-mentioned adjustable tension scissors, the bottom end of the second bearing is flush with the bottom end of the support ring, and they are both supported in the annular groove recessed on the side of the second blade body.

[0013] Preferably, in the above-mentioned adjustable tension scissors, the end of the first bearing away from the second bearing protrudes outward to form an annular stop surface, which is supported between the top surface of the arc-shaped spring and the head of the connecting bolt.

[0014] Preferably, the adjustable tension scissors described above are used for hairdressing.

[0015] Compared with existing technologies, the advantage of this technical solution is that it first connects the blades with connecting bolts, which can be roughly adjusted to the basic position required by the two blades. Then, the tightness can be adjusted by adjusting the bolts, and then finely adjusted to the most precise position of the two blades, ultimately achieving almost no friction and achieving the final feel.

[0020] The technical solutions of the present utility model will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Combination Figure 1-3 As shown, the adjustable scissors 100 include a first blade 101 and a second blade 102 hinged together. An arc-shaped spring piece 103 is provided on the side of the first blade 101 opposite to the second blade 102. The scissors also include a connecting bolt 104 and an adjusting bolt 105. The connecting bolt 104 passes through the arc-shaped spring piece 103 and the first blade 101 in sequence, and is then threaded to the second blade 102. The adjusting bolt 105 passes through the arc-shaped spring piece 103 and is then threaded to the first blade 101. The heads of the connecting bolt 104 and the adjusting bolt 105 are respectively supported on the surface of the arc-shaped spring piece 103. The connecting bolt 104 is located near the end of the arc-shaped spring piece 103, and the adjusting bolt 105 is located near the middle of the arc-shaped spring piece 103. In use, the adjusting bolt 105 adjusts the curvature of the arc-shaped spring piece 103, thereby adjusting the friction between the first blade 101 and the second blade 102. The side of the first blade 101 is recessed to form a spring groove 106 for fitting and placing the arc-shaped spring 103.

[0022] In actual operation, since the arc-shaped spring is stuck in the spring slot, the arc-shaped spring and the first cutter body remain as one. After the connecting bolt is threadedly connected to the second cutter body, the first cutter body and the arc-shaped spring are stuck between the second cutter body and the head of the connecting bolt. The arc-shaped spring has a slight curvature. If the first cutter body and the arc-shaped spring are regarded as one, the thickness of the first cutter body can be adjusted.

[0023] The curved spring clip bends only about 0.1-2 millimeters on the surface of the first cutter body. This bend indicates that the thickness can be adjusted. When the connecting bolt is connected, a rough adjustment has been achieved. Tightening or loosening the adjusting bolt at this point will cause the curved spring clip to spring up or press down, thus adjusting the bend of the curved spring clip on the first cutter body, which is equivalent to adjusting the thickness of the first cutter body.

[0024] When the curved spring is pressed down, the overall thickness of the first blade and the curved spring decreases, which reduces the friction between the first blade and the second blade and the connecting bolt, thus reducing the force.

[0025] When the curved spring is ejected, the overall thickness of the first blade and the curved spring increases, which increases the friction between the first blade and the second blade and the connecting bolt, thus increasing the force.

[0026] Furthermore, a gap space 107 is formed between the first blade 101 and the second blade 102 behind the hinge.

[0027] In this embodiment, the back of the ordinary scissors does not make contact with the large area of ​​the contact surface, which further reduces friction and improves the feel.

[0028] Furthermore, a first bearing 108 and a second bearing 109 arranged side by side are sleeved on the outside of the connecting bolt 104. The outside of the first bearing 108 and the second bearing 109 are sleeved on the support ring 110, and the support ring 110 is formed on the arc-shaped spring piece 103.

[0029] In this embodiment, by using two bearings side by side, friction is first reduced by the bearings, and stability is improved by using two bearings side by side, since a single bearing would be unstable.

[0030] Furthermore, the bottom end of the second bearing 109 is flush with the bottom end of the support ring 110, and they are both supported in the annular groove 111 recessed on the side of the second cutter body 102. The end of the first bearing 108 away from the second bearing 109 protrudes outward to form an annular stop surface 112, which is supported between the top surface of the arc-shaped spring piece 103 and the head of the connecting bolt 104.

[0031] In this embodiment, a stable connection between the two bearings is achieved, improving the product's precision.

[0032] Furthermore, it is used for hairdressing.

[0033] In this embodiment, the product is mainly used for hairdressing. Since the scissors are relatively delicate, they are generally not used in other places. However, scissors using this technical solution should all fall within the protection scope of this utility model patent.
