Detailed Description

The chain ring maker as shown in fig. 1-7 comprises a base 1, wherein the base 1 is n-shaped formed by two vertical plates and a top plate, fixed columns 2 are fixedly connected to the top surface of the base 1, the fixed columns 2 are provided with two, the two fixed columns 2 are symmetrically arranged by taking the center of the base 1 as the axis, the two fixed columns 2 are respectively and rotatably connected with a rotating handle 3, the rotating handle 3 comprises a supporting rod 301, a rotating seat 302 and a baffle rod 304, the rotating seat 302 is rotatably connected to the fixed columns 2, the outer wall of the fixed columns 2 is provided with external threads, the center of the rotating seat 302 is provided with a screw hole 303, the screw hole 303 is connected to the external threads of the fixed columns 2, the supporting rod 301 is fixedly connected to the outer wall of the rotating seat 302, the baffle rod 304 is fixedly connected to the supporting rod 301, the baffle rod 304 is parallel to the fixed columns 2, steel bars 5 are clamped between the baffle rod 304 and the fixed columns 2, two ends of the steel bars 5 are respectively clamped between the two fixed columns 2 and the two baffle rods 304, the top surface of the base 1 is fixedly connected with a baffle column 4, the baffle column 4 is arranged at the center of the two fixed columns 2, and the baffle rod 4 is clamped between the two steel bars 4 and the two fixed columns 2.

When the utility model is used, the two rotating handles 3 are rotated to the position that the baffle rods 304 and the baffle columns 4 are basically on the same vertical plane, then the steel bars 5 with determined lengths are placed between the baffle columns 4 and the two fixed columns 2, at the moment, the baffle rods 304 and the baffle columns 4 of the two rotating handles 3 are positioned at one side of the steel bars 5, at the moment, the two rotating handles 3 are rotated, the baffle columns 4 are contacted with the steel bars 5, the steel bars 5 are bent along the outer walls of the two fixed columns 2, after the two ends of the steel bars 5 are aligned, the manufacture of the loop chain is completed, and if necessary, the openings of the loop chain with the bent length can be welded and connected.

The baffle column 4 prevents the steel bars 5 from being bent outwards at the center positions of the two fixed columns 2 during bending, so that the manufacturing quality of the loop chain is protected.

The rotating seat 302 and the fixed column 2 are in threaded connection, so that the relative transmission of the rotating seat 302 and the fixed column 2 is guaranteed, the rotating seat 302 is prevented from falling off from the fixed column 2, and it is noted that, in order to meet the requirement of use, the whole length of the fixed column 2 is generally set to be full threads, the threads of the connecting fixed columns 2 which are the same or opposite can be used, and a certain gap is reserved between the rotating seat 302 and the top plate of the base 1, so that the rotating seat 302 cannot be propped up with the top plate of the base 1 when rotating.

The utility model can be manufactured by utilizing waste materials, for example, the base 1 can be manufactured by using channel steel, the rotating seat 302 can be manufactured by using threads, and the fixed column 2 can be manufactured by cutting a section of bolt.
