Description

Technical Field

[0001] The utility model relates to the technical field of scissors, in particular to a pair of tool scissors with high practicality. Background Art

[0002] Tool scissors, especially electrician scissors, are currently commonly used application tools, and their handiness and portability are particularly important. Tool scissors in the prior art are generally linear, that is, the shears and the handle are on the same axis, such as CN202221283768.0 discloses multifunctional electrician scissors; CN202122734883.7 discloses a special equipment maintenance anti-electric shock electrician scissors; both are linear scissors, and may not be able to operate in gaps or areas with narrow working spaces, and the applicable scenarios are limited. Utility Model Content

[0003] The utility model aims to overcome at least one defect of the above-mentioned prior art and provide a tool shear with high practicality, which can realize multi-angle shearing and can be applied in a wider range of scenarios.

[0004] The utility model discloses a tool shear with high practicality, comprising a first shearing piece, a second shearing piece and a nut fastener; the first shearing piece and the second shearing piece are rotatably connected by the nut fastener; the connecting part is a connecting end, and the two ends are free ends; the first shearing piece comprises a first handle part and a first blade part; the first blade part is embedded in the first handle part; the second shearing piece comprises a second handle part and a second blade part; the second blade part is embedded in the second handle part; the first blade part and the second blade part are connected by the nut fastener; the angle α between the first handle part and the first blade part is 130-170°; the second handle part is coaxial with the second blade part, and in a closed state, the second blade part is coaxially fitted with the first blade part.

[0005] The main invention of the utility model is that the angle between the first handle portion and the first blade portion is designed to be 130° to 170°, and preferably, the angle between the first handle portion and the first blade portion is 140° to 150°. It can be used in ordinary environments or environments with narrow spaces. And because there is a certain angle difference between the blade and the handle, it avoids blocking the line of sight during use, and is more convenient to use.

[0006] Preferably, a first connecting hole is provided on the connecting end of the first blade portion, and the first connecting hole is connected to the second blade portion by inserting the nut fastener; the connecting end and the free end of the first handle portion are V-shaped, and the angle β is 140° to 150°.

[0007] Preferably, a first gripping portion for inserting a thumb is provided at the free end of the first handle portion, and the first gripping portion is quasi-circular; an edge of the first gripping portion is an arc chamfered surface.

[0008] The first handle portion is mainly used for inserting the thumb. In order to match the structure of the thumb, the first grip portion of the utility model is designed to be circular, and its size leaves a small amount of space for the thumb to be inserted, so as to match people with different finger thicknesses, and is set as an arc bevel, so that the hand holding process is more comfortable, and long-term operation does not hurt the hand. For people who use the right hand normally, the connecting end and the free end of the first handle portion are V-shaped, and the direction of the V-shaped bend is opposite to the bending direction between the first handle portion and the first blade portion, so that when the hand is operated, the side close to the line of sight has a larger observation space, reducing the hand's obstruction of the working area. And the multiple bends save more space.

[0009] Preferably, the widths of the first blade portion and the second blade portion decrease gradually from the connecting end to the free end, and the tops of the first blade portion and the second blade portion are flat.

[0010] The design of the first blade part and the second blade part with decreasing widths of the utility model also facilitates the operation of the first shearing piece and the second shearing piece. The flat head design prevents the top from poking people, thereby improving the safety of the product.

[0011] Preferably, a second connecting hole is provided at the connecting end of the second handle portion, and the second handle portion is connected to the first blade portion by inserting the nut fastener into the second connecting hole; a second gripping portion is provided at the free end of the second handle portion, and the second gripping portion is bean-shaped and has an arc chamfered edge.

[0012] Similarly, the second gripping portion of the second handle of the utility model is mainly used for gripping by the index finger, middle finger, ring finger and little finger, which conforms to the general usage habits. And the structural design of the edge of the second gripping portion being an arc chamfer allows more areas to fit the hand, making the operation more comfortable and labor-saving.

[0013] Preferably, an anti-skid groove is provided on the inner side of the second gripping portion, and the pattern of the anti-skid groove is perpendicular to the direction of the axis of the second gripping portion, thus achieving a better anti-skid effect.

[0014] Preferably, a convex column is provided on the inner side of the first handle portion; and a groove matching the convex column is provided on the inner side of the second handle portion.

[0015] In order to ensure that the first handle portion and the second handle fit more closely in a closed state, the utility model adopts a protrusion and a groove design. When not in use, the protrusion is embedded in the groove to avoid safety hazards caused by the separation of the first shear and the second shear when not in use.

[0016] More preferably, the protruding column and the groove are respectively provided with magnets that attract each other, so that the protruding column and the groove can be clamped and fixed to be used as a bottle opener or to clamp other items.

[0017] Furthermore, the nut fastener includes a first nut, a second nut and a plurality of washers; the first nut passes through the washers and the first blade portion in sequence, and the second nut passes through the washers and the second blade portion in sequence, and the connection between the first blade portion and the second blade portion is achieved by locking the first nut and the second nut. The first nut and the second nut are connected in a male nut and female nut manner, and are easy to install. The use of washers can reduce the friction between the nut and the blade, thereby increasing the service life.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] The utility model has a simple structure, a small size, and is easy to carry. The angle between the first handle portion and the first blade portion is designed to be 130 to 170 degrees, so that it can be used in ordinary environments or environments with narrow spaces. The connecting end and the free end of the first handle portion are V-shaped, and the direction of the V-shaped bend is opposite to the bending direction between the first handle portion and the first blade portion, so that when the hand is operating, the side close to the line of sight has a larger observation space, reducing the hand from blocking the working area. The multiple bends save more space.

[0020] Furthermore, the utility model takes usage habits into consideration. Generally, the thumb and the other four fingers form a gripping hand shape. Therefore, the design of the first gripping portion and the second gripping portion better fits the hand shape and saves effort in use. BRIEF DESCRIPTION OF THE DRAWINGS
