By adopting the elastic member 400, when a fit clearance is formed between the stopping member 300 and the sliding surface due to use loss, the stopping member 300 and the first scissors assembly 100 can be always kept in close fit, and the stopping member 300 and the sliding surface are always in a friction fit state, so that the scissors are better ensured to be locked in a closed state, and the safety is improved; and improve the use feeling.

In some embodiments of the present invention, as shown in fig. 1 to 4, the scissors with locking switch of the embodiments of the present invention further include an operating member 500, and the operating member 500 is slidably connected to the first scissors assembly 100. The stopping member 300 is movably disposed on the operating member 500. The operating member 500 can slide the stopping member 300 on the first scissor assembly 100. The elastic member 400 is respectively connected to the operating member 500 and the stopping member 300, so that the stopping member 300 is compressively disposed on the first scissor assembly 100. The scissors structure can be made simpler by using the operating member 500.

The stopping member 300 can be movably disposed on the operating member 500 in a sleeved manner; in this case, the stopping member 300 may be a ring structure, and the operating member 500 may be a shaft structure. The stopping member 300 can be selected in a clamping mode and is movably arranged on the operating member 500; at this time, the stopping member 300 may be a structure having a slot, and the operating member 500 may be in the form of a push cover and is sleeved on the stopping member 300.

Specifically, in some embodiments of the present invention, as shown in fig. 1-4, first scissor assembly 100 is provided with a chute 111. The operation unit 500 is slidably provided in the chute 111. The operation portion can drive the stopping member 300 to slide along the sliding groove 111. The operating member 500 may be slidably disposed on the sliding slot 111 via a slide rail or the like.

In order to make the structure more compact and reasonable, the sliding slot 111 is disposed on the connecting portion of the first scissors assembly 100 and on a side close to the grip portion. In practice, the sliding groove 111 may be disposed on the handle or the blade. The length direction of the sliding slot 111 extends from a side of the connecting portion of the first scissors assembly 100 adjacent to the grip portion to a side adjacent to the pivot hole.

Specifically, in some embodiments of the present invention, as shown in fig. 1 to 4, the elastic member 400 is a spring, one end of which is pressed against the stopping member 300, and the other end of which is pressed against the operation portion. The elastic member 400 may also be in the form of a spring plate or a snap, and the stopping member 300 is pressed against the sliding surface.

Specifically, in some embodiments of the present invention, as shown in fig. 1 to 4, the stopping member 300 is a circular ring structure, the operating portion is an axle structure, and the stopping member 300 is movably sleeved on the operating portion. The diameter of the portion of the operating element 500 that fits the circular hole of the stopper 300 is adapted to the diameter of the circular hole of the stopper 300. The abutting portion 230 is provided with a concave arc surface 231 that fits the outer circumferential surface of the abutting member 300. The length direction of the sliding groove 111 is substantially perpendicular to the pivoting direction of the scissors with the locking switch according to the embodiment of the present invention. When the scissors are in a closed state, the operating element 500 drives the stopping element 300 to slide along the sliding groove 111, so that the outer peripheral surface of the stopping element 300 and the concave arc surface 231 can be abutted with each other, and the first scissors assembly 100 and the second scissors assembly 200 are limited to be opened. Meanwhile, the concave arc 231 applies a pressure to the stopping member 300, which is substantially perpendicular to the groove surface of the sliding groove 111 in the length direction, thereby improving the reliability of the locking. If the abutting portion 230 is designed to have a planar structure at the position of the concave arc 231, the convex portion 232 needs to be extended to ensure the reliability of the locking, which increases the production cost.

In some embodiments of the present invention, as shown in fig. 1-4, the sliding slot 111 extends through both sides of the first scissor assembly 100 facing toward and away from the second scissor assembly 200. The operating member 500 includes: the nut column 510 penetrates through the sliding groove 111, and the bolt 520 is in threaded connection with the nut column 510, so that the operating part 500 is movably arranged on the sliding groove 111. The operating member 500 facilitates the assembly of the scissors by adopting such a screw structure. In operation, the nut column 510 is pressed to disengage the bolt 520 from the first scissors assembly 100, thereby reducing the friction surface between the operating member 500 and the first scissors assembly 100 and making the locking process smoother. The slide groove 111 may be designed as a stepped groove, and one end of the operating element 500 is engaged with and disposed in the slide groove 111.

In some embodiments of the present invention, as shown in fig. 1, 3 and 4, a receiving space 112 is formed between first scissors assembly 100 and second scissors assembly 200. The receiving portion 112 may be disposed on a side of the first scissors assembly 100 facing the second scissors assembly 200, or disposed on a side of the first scissors assembly 100 facing away from the second scissors assembly 200. The accommodating position 112 and the chute 111 are communicated with each other. A portion of the operating member 500 is slidably coupled to the slide slot 111. The remaining portion of the operating element 500 may be entirely received in the receiving portion 112, or partially received in the receiving portion 112. By adopting the structure of the accommodating position 112, the possibility of safety accidents caused by sudden opening of the scissors during operation due to the fact that the locking assembly 300 is loosened by mistake can be reduced. In a practical embodiment, a portion of the nut post 510, the stopping member 300 and the elastic member 400 are received in the receiving position 112, and the nut post 510 slightly protrudes from the receiving position 112 for easy operation.

In some embodiments of the present invention, as shown in fig. 1, 5 to 7, the scissors with locking switch of embodiments of the present invention further include: the torsion spring 600 has a first end 610 and a second end 620 at both ends thereof, respectively. The first scissors assembly 100 has a first concave 113 on a side facing the second scissors assembly 200, and the first end 610 is engaged with the first concave 113. A second concave portion is disposed on a side of the second scissors assembly 200 facing the first scissors assembly 100, and the second end 620 is engaged with the second concave portion 211. The first recess 113 and the second recess 211 cooperate to form a chamber, and the torsion spring 600 is disposed in the chamber. When the scissors tend to close or are in a closed state under the action of external force, the torsion spring 600 can apply torsional force to the scissors.

Specifically, in some embodiments of the present invention, as shown in fig. 1, 5 to 7, the first concave portion 113 and the second concave portion 211 are both circular ring structures, and the two concave portions have the same size, and the central axes thereof coincide with the pivot axis of the scissors with the locking switch according to the embodiment of the present invention. The large circumferential surfaces of the first concave portion 113 and the second concave portion 211 are provided with notches for engaging the first end 610 and the second end 620, respectively. In actual production, the major circular diameters of the first and second recesses 113 and 211 are generally designed to be larger than the outer diameter of the torsion spring 600 in consideration of torsional deformation of the torsion spring 600. A positioning circular truncated cone 114 is arranged in a cavity formed by the first concave position 113 and the second concave position 211. In the embodiment of the present invention, the positioning circular truncated cone 114 is composed of two parts, and the positioning circular truncated cone 114 can be designed into an integrated structure in actual production. The central axis of the positioning boss 114 coincides with the pivot axis of the scissors. The torsion spring 600 is sleeved on the positioning round platform 114. The diameter length of the outer peripheral surface of the positioning round table 114 is adapted to the inner diameter length of the torsion spring 600. By adopting the structure of the positioning round platform 114, the situation that the tail end is separated from the notch and is clamped in the cavity in the use process can be avoided.

In some embodiments of the present invention, as shown in fig. 5 and 6, first scissor assembly 100 includes: a first scissor body 110 and a first grip 120. Second scissor assembly 200 includes: a second scissor body 210 and a second grip 220.
