In the chain attachment groove, a support wall is formed, which is milled in a shape with an arcuate notch. The axial groove is formed at one end of the rod and connected to the chain attachment groove. The screw member has a thread to form a threaded hole with the drilling and cutting, wherein the axial groove, the arcuate notch and the threaded hole are formed coaxially. (c) Heat Treatment: After manufacturing, the rod is heat treated and formed into a chain tool. (d) Sheet Metal Assembly: Select a sheet metal part that is made, after which this sheet metal part is mounted to the chain tool with at least one mounting pin to attach this chain tool to the various sheet metal parts. In this case, the milling and drilling and cutting for the manufacture can be interchanged, while the sheet metal part has a first mounting part and a first machining part. The first mounting part of the sheet metal part is attached to the chain tool, wherein on an outer periphery of the first processing part a plurality of first Einklemmrillen are formed, with which the tension of the spokes can be adjusted. The sheet metal part consists of a compression rod and an actuator. The press rod has a bent end, a machining end and a threaded section, this threaded section being formed between the bent end and the machining end. The actuator is formed with a second mounting part, a plurality of second Einklemmrillen and a second effective edge. The second mounting part of the actuator is attached to the bent end of the press rod, while the machining end of the press rod is first inserted into the threaded hole and then the threaded portion is screwed into the threaded hole. The actuator is formed outside of the chain tool to be able to turn over the press rod in a practical manner and thus to screw the threaded portion in the threaded hole. The bent end of the pressing rod has a cylindrical and a bent shape with a rectangular cross section, wherein a screw or a rivet is used as a fastening pin. The rod has a square, circular or hexagonal shape.

In this arrangement, the chain tool according to the invention 10 produced with a simple process, on the one hand to shorten the production time and on the other hand to reduce the manufacturing costs, so as to reduce the overall manufacturing cost. In addition, with the milling of the present invention, a better appearance of the chain tool becomes as compared with the prior art casting method 10 created. Further, as compared with the prior art casting method, the precision of the milling size and the quality of performance are improved.

In addition, the chain tool 10 and the sheet metal part 2 made separately from each other, ie that the chain tool 10 and the sheet metal part 2 can be produced simultaneously at different locations. This process simplifies the manufacturing steps and shortens the process time to improve manufacturing efficiency. Next is the chain tool 10 with the sheet metal part 2 built, using instead of this sheet metal part 2 other sheet metal parts 2 can be used with other functions as required. Therefore, integrated chain tools with different functions and in different shapes can be made (the sheet metal part 2 the present invention is made with a punching method; In addition, the chain tool 10 and the sheet metal part 2 the present invention separately prepared to shorten the process steps; the production method of the sheet metal part 2 should not be limited by the present invention).

Depending on the requirement, sheet metal parts 2 in different versions and with different functions to the chain tool 10 be attached. By mounting different embodiments of the sheet metal parts 2 to the chain tool 10 can use different folding tools with different functions of chain tools 2 be created quickly to meet the different needs of customers and the market immediately.

The 3 - 6 show that the chain tool 10 depending on different purposes with different embodiments of the sheet metal parts 2 is mounted. A first embodiment of a sheet metal part 2 has a first mounting part 22 and a first processing part 23 on. The first assembly part 22 of the sheet metal part 2 gets to the bottom of the chain tool 10 attached to the sheet metal part 2 at the bottom of the chain tool 10 to fix. On an outer periphery of the first processing part 23 are several first Einklemmrillen 231 shaped, wherein the first mounting part 22 and the first processing part 23 of the sheet metal part 2 are arranged at an angle to the chain tool 10 to wear. With the first Einklemmrillen 231 the tension of the spokes is adjusted. Like in the 5 shown, the sheet metal part 2 at the first processing part 23 continue a recording notch 232 on. The recording notch 232 is with a first opening 233 and a second opening 234 provided, this second opening 234 with the first opening 233 is connected to screw for mounting and dismounting different screws or remove.

The 8th shows a further embodiment of a sheet metal part 2 , The first assembly part 22 of the sheet metal part 2 has two spaced-apart ribs (not shown) around this first mounting part 22 to an outer periphery of the chain tool 10 to fix. The first processing part 23 is at one end with a first effective edge 235 formed while on an outer periphery of this first processing part 23 several first Einklemmrillen 231 are shaped. With the help of the first effective edge 235 a wheel is mounted or removed.

The 2 . 9 . 10 and 11 show that the other embodiment of a sheet metal part 2 from a press bar 3 and from an actuator 4 consists. The press bar 3 has a bent end 31 , an editing end 32 and a threaded portion 33 on, with this threaded section 33 between the bent end 31 and the end of processing 32 is formed. The actuator 4 is with a second mounting part 41 and with a second processing part 42 educated. The second mounting part 41 of the actuator 4 is at the curved end 31 the compression rod 3 attached. The second processing part 42 has several second Einklemmrillen 421 and a second effective edge 422 on. The end of processing 32 the compression rod 3 gets into the threaded hole first 16 introduced, after which the threaded portion 33 into the threaded hole 16 is screwed in. The actuator 4 is outside the chain tool 10 to the press rod 3 practically turn around to the threaded section 33 the compression rod 3 in the threaded hole 16 to rotate.

The 2 - 11 show that a chain 5 from several connecting joints 51 exists, with on both sides next to these connecting joints 51 several columns 52 are formed. For replacing or cleaning the chain 5 a bicycle becomes the chain 5 first lengthwise into the chain mounting groove 11 placed, after which the two ribs of the supporting wall 15 through the columns 52 be introduced to a connecting joint 51 the chain 5 in the arched notch 151 to position, after which the threaded portion 33 the compression rod 3 finally in the threaded hole 16 is screwed in. A method to remove the chain 5 will be described below. First, the chain tool 10 with the sheet metal part 2 carried, after which to a folding tool 6 pivotally mounted press bar 3 into the threaded hole 16 is screwed in. In this way, the folding tool 6 be rotated to the press rod 3 into the threaded hole 16 screw in and around with the editing end 32 the compression rod 3 a connecting joint 51 with the end of processing 32 a connecting joint 51 is pushed. The chain 5 is attached to an inner wall of the chain attachment groove 11 close to the axial groove 13 triggered, with a connecting joint 51 after the axial groove 13 is aligned. In this way, a connecting joint 51 after pushing the end of processing 32 from the chain 5 be removed to the chain 5 to open.

The 11 represents another method of removing the chain 5 dar. The chain tool 10 is pivotal on the folding tool 6 attached. First, the chain tool 10 pivotally in an operating position to the folding tool 6 rotated to the threaded hole 16 to position to the outside, after which the press rod 3 that with the actuator 4 is fastened, in the threaded hole 16 is introduced. Therefore, to remove the chain 5 the actuator 4 rotates to the press rod 3 into the threaded hole 16 screwed. With the actuator 4 becomes the pressing of the pressing rod 3 facilitated in any direction in a practical way. The curved end 31 the compression rod 3 is formed in a cylindrical and bent shape or in a bent shape with a rectangular cross section.

Further, milling and drilling and cutting can be interchanged for manufacture.

Also, the pole points 1 a square, a circular or a hexagonal shape.

As a mounting pin 21 screws or rivets are used. The screws facilitate the assembly of the sheet metal part 2 to the chain tool 10 while with the rivets the strength of the connection between the sheet metal part 2 and the chain tool 10 is improved.
