Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 , Figure 2 , Figure 4The utility model provides an embodiment: a labor-saving patient treatment tweezers, comprising a handle 1, the handle 1 is the part of the tweezers for people to hold, usually adopts a comfortable and non-slip design to ensure that the user can stably operate the tweezers, a cutting edge 2 is arranged on the left side of the handle 1, the cutting edge 2 is the part of the tweezers used to clamp objects, and a labor-saving component is arranged on the top of the handle 1, the labor-saving component comprises a support frame 31 and a guide block 3 connected to the support frame 31, the guide block 3 is arranged in an arc shape, and the guide block 3 is arranged in an arc shape so that when the two groups of handles 1 move toward the middle, the support frame 31 is driven to move in an arc shape, so that the support frame 31 can be matched with the trajectory of movement of the support frame 31 and the handle 1, and the outer wall of the guide block 3 is slidably connected with a support frame 31 connected to the handle 1 and matched with a round rod 36 to slide into a round groove 35 to limit the handle 1, and two groups are arranged, and the two groups of support frames 31 are symmetrically arranged with the center line of the guide block 3 as the symmetry axis.

[0032] Furthermore, the support frame 31 is fixedly connected to the top of the handle 1, and the front surface of the guide block 3 is fixedly connected with a fixed block 32 to prevent the support frame 31 from moving out. The top of the guide block 3 is slidably connected with a round rod 36 that slides into the round groove 35 to limit the support frame 31 and the handle 1, and multiple groups of round rods 36 are provided. The multiple groups of round rods 36 are symmetrically arranged with the center line of the guide block 3 as the symmetry axis. The top of the front surface of the round rod 36 is set as an inclined surface. By setting the top of the front surface of the round rod 36 as an inclined surface, the round rod 36 can be squeezed when the support frame 31 moves to make the round rod 36 move downward, driving the arc block 3 After the squeezing spring 34 is moved downward, the reverse force of the squeezing of the spring 34 can drive the round rod 36 to return and slide into the round groove 35, so that the support frame 31 and the handle 1 can be quickly limited. By limiting the handle 1, the clamped object can be limited. The object can be easily fixed without continuously applying the clamping force, which reduces the burden on the user's hands and achieves the effect of labor saving. At the same time, the continuity and stability of the work are improved. The bottom end of the round rod 36 is fixedly connected with an arc block 37 supporting multiple groups of round rods 36, and the arc block 37 is slidably connected to the inner wall of the guide block 3.

[0033] Reference Figure 1 , Figure 3 , Figure 4 A protective assembly is provided on the left side of the handle 1, and the protective assembly includes a positioning rod 21 supporting the cutting edge 2, the positioning rod 21 is fixedly connected to the front surface of the cutting edge 2, the positioning rod 21 penetrates and is rotatably connected to the front surface of the handle 1, and a positioning block 26 is fixedly connected to the left side of the top end of the handle 1 near the limiting rod 23 to limit the cutting edge 2 so that the limiting groove 25 is aligned with the limiting rod 23.

[0034] Reference Figure 1 , Figure 2 , Figure 4The arc block 37 is elastically connected to the guide block 3 through a spring 34, one end of the spring 34 is fixedly connected to the bottom end of the arc block 37, and the other end of the spring 34 is fixedly connected to the inner wall of the guide block 3. The round rod 36 is squeezed by the support frame 31 so that the round rod 36 pushes the arc block 37 to move downward to squeeze the spring 34. The reverse force of the spring 34 can drive the round rod 36 to reset and slide into the circular groove 35, so that the support frame 31 can be quickly limited, and the right side of the arc block 37 is fixed. A connecting block 38 is fixedly connected to drive the arc block 37 to move. A pressing plate 33 is fixedly connected to the right side of the connecting block 38 to drive the arc block 37 and the round rod 36 to slide out of the circular groove 35 to release the limit of the support frame 31. The connecting block 38 is slidably connected to the right side of the guide block 3. A circular groove 35 is provided on the top inner wall of the support frame 31 near the top of the guide block 3 to cooperate with the round rod 36 to slide into the circular groove 35 to limit the support frame 31 and the handle 1. The round rod 36 slides on the inner wall of the circular groove 35.

[0035] Reference Figure 1 , Figure 3 , Figure 4 The positioning rod 21 is elastically connected to the handle 1 through a torsion spring 22. One end of the torsion spring 22 is fixedly connected to the inner wall of the positioning rod 21, and the other end of the torsion spring 22 is fixedly connected to the front surface of the handle 1. By rotating the cutting edge 2 downward, the positioning rod 21 is driven to rotate and squeeze the torsion spring 22, so that the cutting edge 2 rotates and slides out of the inner side of the handle 1 and rotates to the left side of the handle 1. At this time, the cutting edge 2 contacts the positioning block 26 and is limited. At the same time, the limiting groove 25 is aligned with the limiting rod 23. At this time, the limiting rod 23 can be moved to slide into the limiting groove 25. The cutting edge 2 is limited, and the object can be clamped by the cutting edge 2 at this time. The front surface of the cutting edge 2 is provided with a limiting groove 25 near the left side of the positioning rod 21 to cooperate with the limiting rod 23 to limit the cutting edge 2. The front surface of the handle 1 passes through and is slidably connected with a limiting rod 23 that slides into the limiting groove 25 to limit the cutting edge 2. The limiting rod 23 slides on the inner wall of the limiting groove 25, and the outer wall of the limiting rod 23 is fixedly connected with a limiting plate 24 that prevents the limiting rod 23 from being pulled out of the handle 1. The limiting plate 24 is slidably connected to the inner wall of the handle 1 near the left side of the positioning rod 21.

[0036] Working principle: When in use, after pulling the limit rod 23 outward, the cutting edge 2 is rotated downward to drive the positioning rod 21 to rotate and squeeze the torsion spring 22. After the cutting edge 2 is rotated out of the inner side of the handle 1 to the left side of the handle 1, it contacts the positioning block 26. The cutting edge 2 is limited by the positioning block 26. At this time, pushing the limit rod 23 to slide into the limit groove 25 can limit the cutting edge 2, so that the object can be supported.

[0037] The support frame 31 and the cutting edge 2 are driven to move by pressing the handle 1, and the outer wall of the support frame 31 which is slidably connected to the guide block 3 moves inward to squeeze the inclined surface at the top of the round rod 36, so that the round rod 36 moves downward to push the arc block 37 to move downward to squeeze the spring 34, and the object is clamped between the two sets of cutting edges 2 by the movement of the cutting edge 2. At the same time, the reverse force of the spring 34 being squeezed drives the arc block 37 to reset, and the arc block 37 drives the round rod 36 to reset, so that the round rod 36 slides into the circular groove 35, and the support frame 31 is moved outward to limit the position, preventing the support frame 31 from moving outward. At this time, the handle 1 and the cutting edge 2 can be limited by limiting the support frame 31, so that the object can be continuously clamped through the cutting edge 2, and the object can be easily fixed without continuously applying the clamping force, thereby reducing the burden on the user's hands and improving the continuity and stability of the work.

[0038] When use is finished, the pressing plate 33 can be pressed downward to drive the connecting block 38 and the arc block 37 to move. The movement of the arc block 37 drives the round rod 36 to slide out of the circular groove 35 to release the limit of the multi-support frame 31 and the cutting edge 2, so that the cutting edge 2 can be reset. At this time, the limit of the cutting edge 2 can be released by pulling the limit rod 23 to slide out of the limit groove 25. The reverse force of the torsion spring 22 being squeezed can drive the positioning rod 21 to rotate, thereby driving the cutting edge 2 to rotate, so that the cutting edge 2 rotates to the inner side of the handle 1, and the sharp part of the left end of the cutting edge 2 is protected by the handle 1, so as to prevent accidental touch and injury, thereby improving safety.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
