Description

A kind of power-assisted tailoring scissors

technical field

The utility model relates to the technical field of tailoring tools, in particular to a power-assisted tailoring scissors.

Background technique

With the improvement of living standards, more and more people no longer choose brand ready-made clothes but turn to tailor-made clothes. In the process of cutting and sewing clothes, it is necessary to use tailor scissors to cut and cut the cloth for making clothes. , use the tailor scissors to push the fabric. However, the current tailor scissors have high requirements for force and cloth entry angle.

Chinese patent announcement number CN89203973.6, the title of utility model is labor-saving tailoring scissors, this application discloses a kind of labor-saving tailoring scissors, is suitable for garment processing industry and family application. The main scissors body is straight, the middle part of the main scissors body is connected with the auxiliary scissors head, the outer rear end of the auxiliary scissors head is connected with the auxiliary scissors handle by a pin, a lever is installed in the two scissors handles, and a spring is installed at the inner rear end of the auxiliary scissors head. The other end of the spring is installed on the main shear handle. Install wheels on the lower part of the main shear handle. The existing tailor scissors are of ordinary scissors or tweezers structure, and the flexibility of the fabric is relatively large. Therefore, if the force is not used properly or the cutting angle is wrong during use, it is easy to cause the fabric to fail to be cut. Therefore, it is necessary to propose a power-assisted Tailor-style scissors, convenient to apply the correct cutting force and cutting angle to the cut fabric.

Utility model content

The utility model overcomes the inconvenient disadvantage of the current tailor scissors for cutting soft cloth, and provides a power-assisted tailor scissors, which can assist the cloth to apply suitable cutting force and cutting angle.

In order to solve the above technical problems, the utility model adopts the following technical solutions:

A power-assisted tailoring scissors, comprising an upper handle 1, a lower handle 2 and a blade 4 connected between the upper handle 1 and the lower handle 2, the middle part of the upper handle 1 is hingedly connected to the lower handle 2, two blades 4 are fastened and installed on the ends of the upper handle 1 and the lower handle 2 respectively via two fasteners 5, an elastic member 6 is connected between the upper handle 1 and the lower handle 2, and the two ends of the elastic member 6 are respectively connected On the inside wall of the upper grip 1 and the lower grip 2.

The scissors have a shearing function realized by the principle of leverage. When a person pushes the upper handle 1 and the lower handle 2 away from the hinge point for relative rotation, the two blades 4 rotate with the handle. Under the action of the elastic member 6, the upper handle 1 and the lower handle 2 are reset, and the two blades 4 are closed to realize the cutting function. The upper grip 1 has no top surface, the lower grip 2 has no bottom surface, and the upper grip 1 and the lower grip 2 have the same shape. The elastic member 6 is a torsion spring, and the two arms of the torsion spring abut against the inner walls of the upper handle 1 and the lower handle 2 . The blade 4 and the torsion spring are arranged on the two ends of the upper handle 1 and the lower handle 2 . Two blades 4 cutting edges face each other. The port of the blade 4 is tapered and can be used as a needle cone. The scissors can prevent the blades from being separated in the vertical direction due to improper force, making it impossible to cut.

Preferably, a connecting screw 3 is provided between the upper handle 1 and the lower handle 2, the middle part of the upper handle 1 protrudes to form a connecting column 101, and the lower handle 2 is provided with a mounting hole 201 corresponding to the position of the connecting column 101, and the connecting screw 3 passes through the mounting hole 201 and is screwed with the connecting column 101. The hinged structure of the upper handle 1 and the lower handle 2 constitutes the scissor body 100 . The lower handle 2 protrudes toward the direction of the upper handle 1 to form an annular mounting hole 201 . The connecting post 101 is inserted into the mounting hole 201 for positioning. The connecting screw 3 is threadedly connected with the threaded hole on the connecting column 101 . This method is simple in structure and strong in feasibility.

Preferably, the upper handle 1 and the lower handle 2 are housing structures with a narrow front and a wide rear, and the two blades 4 are installed on the narrow ends of the upper handle 1 and the lower handle 2 respectively. The structure with a narrow front and a wide rear is more ergonomic, fits the palm of the hand, and feels better for long-term use.

Preferably, the side wall of the upper grip 1 is provided with a lower grip ring 8 . When the lower grip 2 fits the palm of the hand and is relatively stationary, the upper grip 1 moves relatively, and the thumb can be inserted into the upper grip ring 7, thereby assisting the opening and closing of the tailor scissors.

Preferably, a lower grip ring 8 corresponding to the upper grip ring 7 is provided on the outer wall of the lower handle 2 . When the upper grip 1 fits the palm of the hand and is relatively stationary, the lower grip 2 moves relatively, and the thumb can be inserted into the lower grip ring 8, thereby assisting the opening and closing of the tailor scissors. When the upper grip 1 and the lower grip 2 have the upper grip ring 7 and the lower grip ring 8 at the same time, the user's thumb and forefinger are inserted into the two grip rings, which is convenient to hold the tailor scissors tightly, puncture through the blade 4 or perform other work.

Preferably, the lower handle 2 is provided with a stopper 9 at one end close to the blade 4, and the stopper 9 is used to prevent reverse rotation of the upper handle 1 and the lower handle 2. The so-called reverse rotation is to prevent the upper handle 1 and the lower handle 2 from rotating against the normal rotation direction. At this time, the elastic member 6 cannot restore the upper handle 1 and the lower handle 2 to zero. The stopper 9 is arranged on the side wall of the lower handle 2 and is perpendicular to the direction of rotation. The height of the stopper 9 exceeds the lower handle 2 and interferes with the upper handle 1 . When the reverse rotation occurs, it will interfere with the stopper 9.

Preferably, the height of the top surface of the block 9 is higher than that of the top surface of the handle 1 . Although the stopper 9 can interfere with the upper handle 1, there is a possibility that the upper handle 1 crosses the stopper 9, and when the height of the top surface of the stopper 9 is set higher than the height of the top surface of the last handle 1, it can be further improved. Avoid reverse rotation.

Preferably, the connecting post 101 is in the shape of a cylinder, the mounting hole 201 is a rectangular hole, and the mounting hole 201 can be inserted into the connecting post 101 . The connecting post 101 and the mounting hole 201 are clearance fit. When the upper handle 1 and the lower handle 2 are relatively rotated, the connecting column 101 is also shifted in the rectangular hole, thereby changing the relative position of the upper handle 1 and the lower handle 2, which can meet different tailoring process requirements and User's grip habit.

Preferably, a mounting sleeve 202 is provided at the rear of the lower grip 2 , and the elastic member 6 is sleeved on the mounting sleeve 202 . The installation sleeve 202 effectively prevents the elastic member 6 from moving, so that the power-assisted tailoring scissors can be used normally.

Preferably, the upper grip 1, the lower grip 2, the upper grip ring 7, the lower grip ring 8 and the stopper 9 are made of hard plastic materials. The hard plastic material has the advantages of high strength and light weight, and is suitable as a material for small tailoring tools. It is not easy to fatigue when holding for a long time.

Compared with the prior art, the beneficial effects of the utility model are: (1) Compared with traditional scissors, the range of action between the fingers is smaller, and it is not easy to fatigue after long-term use; The rotation of the grip exceeds the rotation limit, causing the scissors to be damaged; (3) By setting the connecting column and the installation hole, it is convenient to adjust the relative position of the upper grip and the lower grip, which can meet the requirements of different tailoring techniques and the gripping habits of users.
