[0042] like Figures 1 to 8 As shown, an embodiment of the present invention provides a fixture, including a base 100, a first positioning member 200, a second positioning member 300, a third positioning member 400, a limiting member 500, an adjusting member 600 and a supporting member 700, and the first positioning member 200, the second positioning member 300, the third positioning member 400, the limiting member 500, the adjusting member 600 and the supporting member 700 are all detachably connected to the base 100.

[0043] Specifically, the base 100 is provided with a mounting hole 120 which runs through the upper and lower ends thereof, and the first positioning member 200, the second positioning member 300, the third positioning member 400 and the limiting member 500 are all installed at the mounting hole 120, and the third positioning member 400 is located on the left side of the first positioning member 200, and the second positioning member 300 is located on the right side of the first positioning member 200, the two limiting members 500 are respectively arranged on the front and rear sides of the third positioning member 400, the two adjusting members 600 are respectively arranged on the front and rear sides of the second positioning member 300, and the supporting member 700 is arranged on the left side of the third positioning member 400, and is respectively limited at the mounting hole 120 by a latch (not shown in the figure). When disassembling and replacing, the latch can be removed, which is convenient to operate and has high work efficiency.

[0044] Furthermore, the hinge 800 can be placed on the upper end of the base 100, and the first positioning member 200 is provided with a first groove 210 corresponding to the cylinder 860 on the hinge 800, and the second positioning member 300 is provided with a second groove 310 and a third groove 320 that can correspond to the first groove 210. Specifically, the first groove 210 is arranged along the axial direction of the cylinder 860.

[0045] Furthermore, the first receiving groove 210 and the second receiving groove 310 can form a first type groove (not shown in the figure), and the first receiving groove 210 and the third receiving groove 320 can form a second type groove (not shown in the figure), and the length of the second type groove is greater than the length of the first type groove. When in use, the staff can choose to use the first type groove and the second type groove according to the length of the cylinder 860. Specifically, by removing the second positioning member 300 for turning, the second receiving groove 310 or the third receiving groove 320 can be made to correspond to the first receiving groove 210, which can reduce the production of different types of fixtures, save costs, and save storage space. The fixture also has the advantages of simple structure and easy disassembly, assembly, maintenance and replacement.

[0046] Furthermore, when the hinge 800 is placed on the upper end of the base 100, the oil cylinder 860 thereon will be limited to the first type groove or the second type groove so that the axes of the adjusting wire 820 and the eccentric nail 830 on the hinge 800 are perpendicular to the horizontal plane, so as to facilitate the disassembly and assembly of the adjusting wire 820 and the eccentric nail 830 in the subsequent process, thereby improving the disassembly and assembly efficiency and accuracy.

[0047] In one embodiment, the third positioning member 400 is provided with a third groove 410 corresponding to the triangular member 870 on the hinge 800 at both upper and lower ends, that is, the two third grooves 410 can be replaced to increase the service life of the third positioning member 400, reduce the production of the third positioning member 400, and save costs.

[0048] In one embodiment, the limiting member 500 is provided with a first limiting surface 510 and a second limiting surface 520 which can correspond to the third groove 410. The distance between the first limiting surfaces 510 on the two limiting members 500 when they are relative to each other is smaller than the distance between the second limiting surfaces 520 on the two limiting members 500 when they are relative to each other, so as to adapt to the positioning of two triangular members 870 of different widths. When in use, the two first limiting surfaces 510 can be relative to each other or the two second limiting surfaces 520 can be relative to each other according to the triangular members 870 of corresponding widths, which can further reduce the production of different types of fixtures and save costs and storage space.

[0049] In one embodiment, a first limiting surface 510 and a second limiting surface 520 are provided at both upper and lower ends of the limiting member 500, and the first limiting surface 510 and the second limiting surface 520 are arranged back to back to facilitate replacement and use, so as to increase the service life of the limiting member 500 and save production costs. It should be noted that the surface opposite to the first limiting surface 510 is formed by being recessed in the direction of the first limiting surface 510 to form the second limiting surface 520.

[0050] In one embodiment, a second receiving groove 310 and a third receiving groove 320 are provided at both upper and lower ends of the second positioning member 300, and the second receiving groove 310 on the same end is arranged opposite to the third receiving groove to improve the utilization rate of the second positioning member 300, increase the service life, reduce the production of the second positioning member 300, and save production costs, and the second receiving groove 310 at the upper end is connected with the second receiving groove 310 at the lower end to facilitate processing and production.

[0051] In one embodiment, a notch 220 is further provided on the right side of the first receiving groove 210 , and the notch 220 corresponds to the pin 880 connecting the oil cylinder 860 and the base 100 . The notch 220 has the function of avoiding the pin 880 and facilitates the subsequent disassembly and assembly of the pin 880 .

[0052] In one embodiment, an abutment portion 710 is provided on the supporting member 700, and two abutment portions 710 are provided at intervals along the width direction of the base 100, forming a limiting groove 720 corresponding to the spring sheet 840 on the hinge 800, and the connecting shaft 850 connecting the spring sheet 840 can abut against the abutment portion 710, that is, through the cooperation of the abutment portion 710 and the limiting groove 720, the stability of the placement of the hinge 800 is further guaranteed. It should be understood that the supporting member 700 can be integrally provided with the base 100 in some embodiments.

[0053] In one embodiment, when the hinge 800 with the base 900 is placed on the upper end of the base 100, the base 900 thereon can abut against the upper end of the adjusting member 600, so that the axial directions of the adjusting wire 820 and the eccentric nail 830 thereon are perpendicular to the horizontal plane, that is, the hinge 800 with the base 900 is supported by the adjusting member 600. Further, the upper end of the adjusting member 600 is provided with a supporting portion 610 protruding upward. When the hinge 800 is placed on the upper end of the base 100, the arm body 810 thereon can abut against the upper end of the supporting portion 610, so that the axial directions of the adjusting wire 820 and the eccentric nail 830 thereon are perpendicular to the horizontal plane. It is perpendicular to the horizontal plane. It should be noted that the hinge 800 here is a hinge 800 without a base 900. When in use, the adjusting part 600 is removed and the position of the adjusting part 600 is adjusted so that the upper end of the adjusting part 600 corresponds to the arm body 810 on the hinge 800 without a base 900, or the upper end of the supporting part 610 corresponds to the base 900 on the hinge 800 with a base 900. In this way, the adjusting part 600 can adapt to two different types of hinges 800, which can reduce the production of different types of fixtures, save costs, and save storage space.

[0054] In one embodiment, a connection portion 620 extending downward is disposed at the lower end of the adjustment member 600, and a connection hole 110 adapted to the connection portion 620 is disposed on the base 100, that is, the connection portion 620 can be inserted into the connection hole 110, which is convenient for processing and operation.

[0055] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
