[0032] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0033] Example

[0034] like Figure 1 As shown, a diagonal cutting pliers with adjustable pliers handle angles comprises a pair of pliers heads 1, a pin shaft 2, a pair of pliers handles 3 and a pair of adjusting members 4.

[0035] A pair of pliers 1 are hinged via the pin 2; Figure 2 As shown, the upper and lower ends of the tail of the pliers head 1 extend horizontally outward to form an extension portion 5; the upper surface of the extension portion located at the upper end of the tail of the pliers head 1 is recessed downward to form a first placement groove 6; the lower surface of the extension portion located at the lower end of the tail of the pliers head 1 is recessed upward to form a second placement groove; the bottom of the first placement groove and the bottom of the second placement groove are both provided with a first tooth-shaped through hole 7, and the first tooth-shaped through holes 7 respectively penetrate the extension portion 5 where they are located, and the two first tooth-shaped through holes 7 share the same axis.

[0036] like Figure 3 As shown, a pair of the pliers handles 3 have second tooth-shaped through holes 8 on their front ends.

[0037] like Figure 4 As shown, a pair of adjusting members 4 each include a sleeve 10, a cover body 11, a screw 12 and a spring 13; the top of the sleeve 10 is provided with a first toothed ring 14, and the side wall of the sleeve 10 is provided with a second toothed ring 15, the first toothed ring 14 and the second toothed ring 15 are both adapted to the first toothed through hole 7, and the second toothed through hole 8 is adapted to the second toothed ring 15, and the bottom of the sleeve 10 is provided with a limiting circular plate 16; the sleeve 10 passes through the first placement groove 6 and the second placement groove respectively; the cover body 11 covers the top of the sleeve 10; the screw 12 is vertically arranged in the sleeve 10; the front end of the screw 12 passes through the cover body 11 and extends into the sleeve 10, contacting the top of the spring 13.

[0038] like Figure 5 As shown, a pair of the pliers handles 3 are sleeved on the second tooth ring 15 on the sleeve tube 10 through their own second tooth-shaped through holes 8 and are located between the two extension portions 5 .

[0039] When it is necessary to adjust the angle of the two pliers handles 3, the staff presses the screw 12, and the head of the screw 12 drives the cover body 11 and the sleeve tube 10 to move downward, so that the first tooth ring 14 and the second tooth ring 15 are respectively disengaged from the two first tooth-shaped through holes 7. Due to the limiting effect of the cover body 11 and the circular plate 16, the sleeve tube 10 will not fall off. After the pliers handle 3 is rotated to a suitable angle, the pressed screw 12 is released. Under the action of the elastic force of the spring 13, the sleeve tube 10 moves upward, so that the first tooth ring 14 and the second tooth ring 15 are respectively engaged with the two first tooth-shaped through holes 7, and the angle adjustment of the pliers handle 3 is completed.

[0040] In this embodiment, the spring 13 is a pagoda-shaped spring. In the same installation space, a pagoda-shaped spring of the same volume can withstand greater pressure than an ordinary compression spring, and accordingly can store more energy, and can withstand greater pressure under the same deformation amount.

[0041] In this embodiment, if Figure 6 As shown, a rubber sleeve 17 is sleeved on the clamp handle 3 to facilitate the staff to hold it.

[0042] Furthermore, the front end of the clamp handle 3 has a raised limiting portion 9 to limit the rubber sleeve 17 .

[0043] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present invention.
