At this time, the driving ring 816 is driven to rotate by the threaded rod. Since the top of the eccentric retaining frame 815 is an open structure, the inner wall of the driving ring 816 will engage with the surface of the driven gear 813. At this time, when the driving ring 816 rotates, the driving ring 816 will drive the driven gear 813 to rotate, so that the driven gear 813 drives the first driving screw 803 to rotate through the telescopic rod 812.

[0045] Working principle: When in use, the invention drives the movable frame 3 to move horizontally relative to the fixed frame 2 through the screw slide 14 when the C-shaped steel needs to be adjusted, that is, when the distance between the fixed rolling wheel 10 and the movable rolling wheel 11 needs to be adjusted, so that the movable frame 3 drives the movable rolling wheel 11 to move horizontally relative to the fixed rolling wheel 10 through the second movable seat 6 and the second roller 7, thereby achieving the purpose of adjusting the distance between the fixed rolling wheel 10 and the movable rolling wheel 11. When the thickness of the C-shaped steel needs to be adjusted, that is, when the distance between the two fixed rolling wheels 10 and the two movable rolling wheels 11 needs to be adjusted, the second driving screw 12 is driven to move up and down through the screw linkage lifting module 13, so that the second driving screw 12 drives the first roller 5 and the second roller 7 located at the top to move up and down through the first movable seat 4 and the second movable seat 6, and achieves the purpose of adjusting the distance between the two fixed rolling wheels 10 and the two movable rolling wheels 11.

[0046] When the fixed rolling wheel 10 and the movable rolling wheel 11 need to be disassembled and replaced, a threaded rod that matches the threaded hole on the surface of the driving ring 816 is used, and the threaded rod is threadedly connected to the threaded hole on the surface of the driving ring 816. At this time, the driving ring 816 is driven to rotate by the threaded rod. Since the top of the eccentric retainer 815 is an open structure, the inner wall of the driving ring 816 will mesh with the surface of the driven gear 813. At this time, when the driving ring 816 rotates, the driving ring 816 drives the driven gear 813 to rotate, so that the driven gear 813 drives the first driving screw rod 803 to rotate through the telescopic rod 812, and when the first driving screw rod 803 rotates, the first driving screw rod 803 drives the first articulated seat 804 and the second articulated seat 805 at the corresponding positions to move away from each other, and the first articulated seat 804 and the second articulated seat 805 drive the first articulated arm 806 and the second articulated arm 807 to be hinged around the connecting shaft 810, wherein the first articulated seat 804 and the second articulated seat 805 are arranged The guide frame 811 can guide the movement of the connecting shaft 810, so that the connecting shaft 810 always moves along the radial direction of the first driving screw rod 803. When the first hinge seat 804 and the second hinge seat 805 move away from each other and the first hinge arm 806 and the second hinge arm 807 are hinged to each other, the first hinge arm 806 will pass through the positioning hole 818 from the inner wall of the annular groove 817 and return to the inner wall of the first connecting sleeve 801 and the second connecting sleeve 802. At the same time, the second hinge arm 807 returns from the inner wall of the positioning hole 818 to the inner wall of the first connecting sleeve 801 and the second connecting sleeve 802. At this time, the movement of the fixed rolling wheel 10 and the movable rolling wheel 11 away from one end of the positioning ring 823 is no longer hindered. Then, the first connecting sleeve 801 and the second connecting sleeve 802 are moved toward one end of the second roller shaft 7, so that the first connecting sleeve 801 is separated from the first roller shaft 5. At this time, the fixed rolling wheel 10 can be disassembled, and then the movable rolling wheel 11 can be disassembled;

[0047] When the fixed rolling wheel 10 and the movable rolling wheel 11 need to be installed, the fixed rolling wheel 10 and the movable rolling wheel 11 are first sleeved on the surfaces of the first roller shaft 5 and the second roller shaft 7 respectively, and the fixed rolling wheel 10 and the movable rolling wheel 11 are initially pressed against the positioning ring 823. At this time, the driving ring 816 is driven to rotate in the opposite direction through the threaded rod, and the driving ring 816 drives the driven gear 813 to rotate in the opposite direction, so that the driven gear 813 drives the first driving screw rod 803 to rotate in the opposite direction through the telescopic rod 812, which will cause the first driving screw rod 803 to drive the first articulated seat 804 and the second articulated seat 805 at the corresponding positions to approach each other, and the first articulated seat 804 and the second articulated seat 805 drive the first articulated arm 806 and the second articulated arm 807 to be articulated around the connecting shaft 810, and the first articulated arm 806 and the second articulated arm 807 are articulated in the articulated During the process, the first connecting sleeve 801 and the second connecting sleeve 802 are penetrated, wherein since the length of the first articulated arm 806 is greater than the length of the second articulated arm 807, the first articulated arm 806 will penetrate the positioning hole 818 and extend into the inner wall of the annular groove 817, and the second articulated arm 807 will be located on the inner wall of the positioning hole 818. During the process that the first articulated seat 804 and the second articulated seat 805 continue to move relative to each other, the first articulated arm 806 will drive the first positioning block 808 to press against one side of the inner wall of the annular groove 817, and the second articulated arm 807 will drive the second positioning block 809 to press against the side of the positioning hole 818 opposite to the first positioning block 808, until the fixed rolling wheel 10 and the movable rolling wheel 11 are pressed against one end of the positioning ring 823 to complete the installation, thereby achieving the purpose of quickly installing the fixed rolling wheel 10 and the movable rolling wheel 11;

[0048] By setting a first connecting frame 821, wherein the first connecting frame 821 is fixed on the inner wall of the first connecting sleeve 801, and the first connecting frame 821 is close to the position of the positioning hole 818, since the first roller shaft 5 is an open structure at one end, when the first connecting sleeve 801 is inserted into the inner wall of the first roller shaft 5, the first connecting frame 821 naturally corresponds to the position of the positioning hole 818, so that the first connecting frame 821 preliminarily positions the position of the guide frame 811 through the positioning spring 820, so that when the second articulated arm 807 and the first articulated arm 806 in the inner wall of the first connecting sleeve 801 are hinged, they can enter the inner wall of the annular groove 817 and the positioning hole 818, and the first articulated arm 806 and the second articulated arm 807 cooperate with the annular groove 817 and the positioning hole 818 to fix the fixed rolling wheel 10, while also realizing the fixed installation between the first connecting sleeve 801 and the first roller shaft 5, and at the same time, by setting a second connecting frame 822, wherein the second connecting frame 822 penetrates the second connecting sleeve 802 The second connecting frame 822 is fixed to the inner wall of the second roller shaft 7, so that the second connecting frame 822 moves with the movement of the second roller shaft 7, that is, the second connecting frame 822 still corresponds to the position of the positioning hole 818 of the second roller shaft 7, so that the second connecting frame 822 can preliminarily position the position of the guide frame 811 through the positioning spring 820, that is, when the second articulated arm 807 and the first articulated arm 806 in the inner wall of the second connecting sleeve 802 are hinged, they can enter the inner wall of the annular groove 817 and the positioning hole 818, and through the second connecting The length of the movable groove 819 on the side wall of the sleeve 802 is greater than that of the movable groove 819 on the side wall of the first connecting sleeve 801, so that the design of the movable groove 819 on the side wall of the second connecting sleeve 802 meets the need when the second roller shaft 7 drives the movable rolling wheel 11 away from the fixed rolling wheel 10, that is, the first articulated arm 806 and the second articulated arm 807 inside the second connecting sleeve 802 move with the movement of the second roller shaft 7 and the movable rolling wheel 11, and will not affect the distance adjustment between the fixed rolling wheel 10 and the movable rolling wheel 11.
