[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0034] Reference Figure 1-6, the utility model provides an embodiment: a half-axis circlip pliers with adjustable jaw size, comprising a rotating shaft 1, a first rotating disk 2 is rotatably connected to the middle part of the rotating shaft 1, and a second rotating disk 3 is rotatably connected to the upper and lower ends of the rotating shaft 1, a handle 4 is fixedly connected to the right side of the first rotating disk 2 and the second rotating disk 3, a telescopic sleeve 5 is slidably connected to the outer wall of the right end of the handle 4, and a first fastener 6 is threadedly connected to the opposite side of the left end of the telescopic sleeve 5, a connecting plate 7 is fixedly connected to the left side of the second rotating disk 3 and the first rotating disk 2, a sliding block 8 is slidably connected to the middle part of the connecting plate 7, a jaw body 9 is fixedly connected to the front side of the sliding block 8, a jaw 10 is arranged on the opposite side of the jaw body 9, and an adjustment component is installed on the opposite end of the sliding block 8;

[0035] The handle 4 drives the first turntable 2 and the second turntable 3 to rotate around the rotating shaft 1, thereby driving the connecting plate 7, the sliding block 8 and the pliers mouth body 9 to rotate around the rotating shaft 1, so as to complete the clamping of objects; the first fastener 6 is rotated to cancel the fixation of the telescopic sleeve 5, and the telescopic sleeve 5 is slid to the right. After adjusting to a suitable position, the first fastener 6 is rotated to fix the telescopic sleeve 5, so as to adjust the length of the handle 4, so as to better meet different work requirements and improve comfort and convenience.

[0036] A limiting groove 11 is provided on the upper side of the connecting plate 7, and a through hole 12 is provided on the opposite end of the connecting plate 7. The adjusting assembly includes a lifting column 13 and a fixed block 17. The front and rear sides of the upper end of the lifting column 13 are fixedly connected to the limiting block 14. A movable groove 15 begins to be provided in the middle of the lifting column 13. A first connecting column 16 is fixedly connected to the lower side of the inner wall of the movable groove 15, and a second connecting column 18 is fixedly connected to the lower side of the fixing block 17. A spring 19 is fixedly connected to the outer wall of the second connecting column 18. A second fastener 20 is penetrated through the rear end of the fixing block 17. The lower end of the lifting column 13 is slidably connected to the middle part of the sliding block 8. The outer wall of the limiting block 14 is tightly matched with the inner wall of the limiting groove 11. One end of the second connecting column 18 is movably connected to the inside of the movable groove 15. The lower end of the spring 19 is fixedly connected to the outer wall of the first connecting column 16. One end of the second fastener 20 is threadedly connected to one end of the sliding block 8.

[0037] The lifting column 13 is pressed upward from the bottom of the lifting column 13 to make the lifting column 13 slide upward inside the sliding block 8 and compress the spring 19 to disengage the limit block 14 from the limit groove 11. At this time, the sliding block 8 and the pliers mouth body 9 can be moved to both sides, and then the lifting column 13 is released. The elastic force of the spring 19 makes the lifting column 13 move downward. At this time, the limit block 14 and the limit groove 11 cooperate again to complete the adjustment of the pliers mouth size, and objects of different sizes can be clamped, thereby improving the applicability of the circlip pliers. The sliding block 8 is moved to the outermost end of the connecting plate 7, and the second fastener 20 is removed through the through hole 12 with a tool, so that the circlip pliers can be disassembled, which is convenient for maintenance.

[0038] Working principle: The handle 4 drives the first turntable 2 and the second turntable 3 to rotate around the rotating shaft 1, thereby driving the connecting plate 7, the sliding block 8 and the pliers mouth body 9 to rotate, so as to complete the clamping of the object, and the first fastener 6 is rotated to cancel the fixation of the telescopic sleeve 5, and the telescopic sleeve 5 is slid to the right. After adjusting to the appropriate position, the first fastener 6 is rotated to fix the telescopic sleeve 5, and the lifting column 13 is pressed upward from the bottom of the lifting column 13 to make the lifting column 13 slide upward inside the sliding block 8 and compress the spring 19 to make the limit block 14 disengage from the limit groove 11. At this time, the sliding block 8 and the pliers mouth body 9 can be moved to both sides, and then the lifting column 13 is released, and the lifting column 13 is moved downward by the elastic force of the spring 19. At this time, the limit block 14 and the limit groove 11 cooperate again to complete the adjustment of the pliers mouth size, and the sliding block 8 is moved to the outermost end of the connecting plate 7. The second fastener 20 is removed by a tool through the through hole 12, so that the circlip pliers can be disassembled.
