[0020] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, an electric scissors provided in an embodiment of the present application has a structure including a casing 1, a switch trigger 2, a spring 3 connecting the switch trigger 2 and the casing 1, a movement 4 arranged in the casing 1, and a movable blade 5 driven by the movement 4 and located outside the casing 1, and the casing 1 is movably connected to the switch trigger 2. It also includes a locking twist 6, which includes a main body 61 slidably connected to the casing 1, a No. 1 protrusion 62, a No. 1 side groove 63 and a No. 2 side groove 64 arranged on the side of the main body 61, a No. 1 limiting end 65 and a No. 2 limiting end 66 respectively arranged at both ends of the main body 61, the switch trigger 2 is provided with a step 20 that can be limited by the No. 1 protrusion 62, the No. 1 side groove 63 and the No. 2 side groove 64 are arranged along the sliding direction of the main body 61, the casing 1 is provided with an elastic buckle 101 that can be engaged with the No. 1 side groove 63 or the No. 2 side groove 64, the No. 1 limiting end 65 and the No. 2 limiting end 66 extend out from both sides of the casing 1 respectively, when the No. 1 side groove 63 is engaged with the elastic buckle 101, the No. 1 protrusion 62 and the step 20 are not limited, and when the No. 2 side groove 64 is engaged with the elastic buckle 101, the No. 1 protrusion 62 and the step 20 are limited.

[0022] In actual use, when the step 20 is not in contact with the first protrusion 62, the first side groove 63 is engaged with the elastic buckle 101. When the switch trigger 2 is pressed to put the electric scissors in a locked state, the lock knob 6 is pushed so that the body 61 drives the first protrusion 62 to move to the side of the step 20 and form a limit with the step 20. At this time, the second side groove 64 is engaged with the elastic buckle 101. In this state, the switch trigger 2 cannot be pressed normally. When the electric scissors need to work, the lock knob 6 is pushed in the opposite direction so that the elastic buckle 101 is engaged with the first side groove 63. At this time, the first protrusion 62 is not limited by the step 20, and the switch trigger 2 can work normally.

[0023] In the above design, the mechanical limit of the lock knob 6 and the switch wrench, together with the traditional software locking of the moving blade 5, form a double protection, effectively preventing the risk of personal injury and making the structure of the electric scissors safer.

[0024] Specifically: Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, the housing 1 includes a left housing 11 and a right housing 12 which are symmetrical to each other and connecting bolts connecting the left housing 11 and the right housing 12. The elastic buckle 101 is arranged on the side of the left housing 11 relative to the right housing 12, and the step 20 is arranged on the side of the switch trigger 2 relative to the left housing 11.

[0025] In actual use, the lock knob 6 is pushed from the left housing 11 side to the right housing 12 side, so that the step 20 is limited by the first protrusion 62, and the elastic buckle 101 is engaged with the second side groove 64. The lock knob 6 is pushed from the right housing 12 side to the left housing 11 side, so that the step 20 is disengaged from the first protrusion 62, and the elastic buckle 101 is engaged with the first side groove 63.

[0026] In the above design, the structural design of the housing 1 facilitates the installation of the locking knob 6 .

[0027] Specifically: Figure 7 As shown, there are multiple elastic buckles 101, and multiple elastic buckles 101 are simultaneously engaged with the first side groove 63 or the second side groove 64.

[0028] In the above design, the number of the elastic buckles 101 is set to be multiple to ensure greater stability when the first side groove 63 or the second side groove 64 is engaged.

[0029] Specifically: Figure 5 As shown, the first side groove 63 and the second side groove 64 are arranged on the same side of the body 61, and the protrusion and the first side groove 63 are respectively located on both sides of the protrusion.

[0030] In the above design, the volume of the locking knob 6 can be effectively reduced, thus saving costs and assembling difficulty.

[0031] Specifically: Figure 5 As shown, the first side groove 63 and the second side groove 64 are the same.

[0032] In the above design, the first side groove 63 and the second side groove 64 are the same, so that the pressing force on the lock knob 6 can be the same.

[0033] To further explain in detail, it should be understood that the above is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
