Background

The scissors are double-edge tools for cutting sheet or linear objects such as cloth, paper, steel plates, ropes, round steel and the like, and the two edges of the scissors are staggered and can be opened and closed. Common scissors all are simplest structure in the existing market, mainly including controlling two scissors arms, the middle part symmetric position of two scissors arms is articulated through the round pin axle to this round pin axle is the demarcation point, and the scissors arm is divided into power arm and resistance arm, and the pointed end of scissors arm (being resistance arm) is used for shearing the object, and the other end of scissors arm (being power arm) is connected with the scissors handle, and the scissors handle is used for the staff to grip. For objects with large thickness (such as crayons), the purpose of saving labor can be achieved only by using a longer power arm during cutting, but the length of the power arm of the common scissors is fixed and unadjustable, so that the objects with large thickness are inconvenient to cut; on the contrary, for objects with small thickness, only a small power arm is needed, but the span of the objects is often large (such as paper), the shearing opening is long, the purpose of convenient shearing can be achieved only by the longer power arm during shearing, and the cut of the sheared objects is relatively flat. The common scissors do not have the function of adjusting the force arm and can not adapt to different use scenes.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the following will explain the contents of the present invention in detail with reference to the accompanying drawings and the detailed description. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some but not all of the relevant portions of the present invention are shown in the drawings.

As shown in fig. 1, this embodiment provides an adjustable scissors, including two scissor arms 1 that match the setting, the power arm end of two scissor arms 1 has all covered handle 2, and two scissor arms 1 all correspond along the blade direction and are provided with one row of evenly distributed's the round hole 3 that runs through, and every two adjacent runs through and communicate through avoiding groove 4 between the round hole 3, and the round hole 3 department that runs through that two scissor arms 1 correspond articulates through fixing device 5.

The utility model discloses a set up the round hole 3 that runs through of intercommunication at the surperficial straight line of shear arm 1, set up fixing device 5 again as the articulated elements, the user only needs two arbitrary correspondences of selection to run through round hole 3 to install fixing device 5 on running through round hole 3, can adjust shear arm 1's arm of force length.

As shown in fig. 3, the fixing device 5 includes a first limiting member 51, a fixing member 52, an adjusting rod 53, a second limiting member 54 and a third limiting member 55, one end of the first limiting member 51 and one end of the fixing member 52 are concentrically installed, the other end of the fixing member 52 and one end of the adjusting rod 53 are concentrically installed, the second limiting member 54 is sleeved on an outer wall of the adjusting rod 53, the adjusting rod 53 and the second limiting member 54 are in interference fit, and the third limiting member 55 is installed at the other end of the adjusting rod 53. As shown in fig. 2, the fixing member 52 is in transition fit with the through hole 3, and the first limiting member 51 and the second limiting member 54 are respectively closely attached to the outer sides of the two scissor arms 1.

Obviously, the above-mentioned fixing element 52 is present as a pin, and its function is mainly to limit the relative circumferential movement of the two scissor arms 1, i.e. the basic movement of the scissors (repeated opening and closing), and the diameter of the adjusting rod 53 is smaller than the width of the avoiding groove 4, so that the whole fixing device 5 can smoothly pass through the avoiding groove 4, and the fixing device 5 can be transferred to any through circular hole 3. The first limiting member 51 and the second limiting member 54 mainly function to limit the fixing member 52 in the through hole 3, so the diameters of the first limiting member 51 and the second limiting member 54 need to be larger than the diameter of the adjusting rod 53, and since the size of the fixing member 52 is matched with the size of the through hole 3, when the first limiting member 51 and the second limiting member 54 are respectively clamped at the outer sides of the two scissor arms 1, the fixing member 52 is clamped at the through hole 3, and the adjusting rod 53 cannot freely pass through the avoiding slot 4. As can be seen from the above description, the second limiting member 54 is movably connected to the adjusting rod 53, and when a user needs to change the arm of force, the limiting function of the second limiting member 54 needs to be released first, so the adjusting rod 53 also serves as a guide post, the second limiting member 54 can slide along the adjusting rod 53 toward the third limiting member 55, so as to provide a space for the fixing member 52 to come out from the opposite direction, and due to the interference fit between the second limiting member 54 and the adjusting rod 53, the second limiting member 54 is not easily loosened, so that the problem of displacement of the two scissor arms 1 during the use of the scissors by the user does not occur. Furthermore, the third limiting member 55 is used to limit the moving distance of the second limiting member 54, so as to ensure that the second limiting member 54 does not fall off the adjusting rod 53 during the moving process.

As one of the preferred embodiments of the present invention, the one end of the first locating part 51 and the second locating part 54 away from the fixing part is set as a round angle, so as to avoid discomfort caused by too large unit pressure intensity born by the hand during pressing.

As one of the preferred embodiments of the present invention, the position where two handles 2 are opposite is provided with a fourth locating part 6, and the fourth locating part 6 is used for limiting the combination angle of two scissor arms 1, and it is excessive to avoid combining.

The working principle is as follows: it should be noted that the fixing device 5 cannot be removed after being installed in the through hole 3, so as to prevent the parts from being scattered and lost.

Mounting and fixing the fixing device 5: firstly, the thumb and the index finger are used for respectively pinching the first limiting part 51 and the third limiting part 55, any two corresponding through round holes 3 are selected, the adjusting rod 53 passes through the avoiding groove 4, the two through round holes 3 move to the other two through round holes 3, then the fixing part 52 is aligned to the through round holes 3, the first limiting part 51 is pressed down, the fixing part 52 is indirectly inserted into the through round holes 3, the preliminary fixing is completed, the second limiting part 54 is pressed down towards the first limiting part 51 (the friction force between the second limiting part 54 and the adjusting rod 53 needs to be overcome), and the mounting and fixing of the fixing device 5 are completed.

Releasing the fixing device 5: firstly, the third limiting member 55 is pressed by a thumb, and since the second limiting member 54 is movably connected with the adjusting rod 53, the third limiting member 55 and the second limiting member 54 are finally pressed on the surface of one of the scissor arms 1, the fixing member 52 is indirectly pushed out from the through circular hole 3, and the adjusting rod 53 enters the through circular hole 3, and since the diameter of the adjusting rod 53 is smaller than the width of the avoiding groove 4, the whole fixing device 5 can move between the through circular holes 3 through the avoiding groove 4.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
