Abstract

The present invention provides a chain riveting tool set, which comprises a body disposed with a chain riveter and bolt members respectively. The bolt member is used for the tool set to pivot through, allowing the tool set to fold or expanded on the body for use. The present invention is characterized in that the tool set further comprises a first and a second auxiliary wrenches which respectively has a recessed curved surface. When the first and second auxiliary wrenches use the bolt members as pivot points to expand, the two recessed curved surfaces are exactly located at two sides of the chain riveter symmetrically, supporting and positioning the chain with the two recessed curved surfaces in advance, so as to facilitate the chain riveter to carry out a chain assembling operation between the two recessed curved surface. This invention is indeed a design having great industrial utilization and progressiveness.

Description

Chain tool set

In particular, the invention particularly relates to a special tool set that can be pre-positioned for the chain to facilitate the chain loading.

When replacing the bicycle chain gear or installing the chain, the chain link of the chain must be dismantled to be carried out. At this time, the chain driver is needed, and the patent case No. I244411 of our country reveals the latest chain tool kit. It mainly integrates the chain cutter with the tools that other bicycles may use, but the patent can not easily carry out subsequent chain loading operations.

Specifically, after the chain link of the chain is disassembled, and the chain of the set length is to be reconnected, since the transmission will apply a predetermined elastic force to the chain, the person must use the hand to pull the chain to overcome The preset spring force is used to position the chain to the tool set, and then the chain link can be assembled by the chain driver. Therefore, when assembling the chain, the one must hold the body of the tool set with one hand, and the other In addition to turning the trigger of the chain driver, it is necessary to free up one hand to hold the chain positioning. This mode of operation is very difficult for us. Therefore, it is very difficult to provide the chain re-issued by the patent. Assembly does not meet the basic requirements for ease of operation.

The reason is that the inventor and the multi-party experimental design finally succeeded in developing the present invention which completely solves the problems in the prior patent application.

The main content of the present invention is to provide a chain tooling kit comprising: a body having a chainer and at least one bolt; and a tool set including first and second auxiliary wrenches, the first The second auxiliary wrench is pivotally connected to the body through the bolt, so that the first and second auxiliary wrenches each have a concave curved surface, and when the first and second auxiliary wrenches are pivoted by the bolt, the second The concave arc surface can be symmetrically located on both sides of the chain driver, so that the two concave arc surface can be positioned first to support the chain support, so that the chainer can perform subsequent chaining operations between the two concave curved surfaces.

The job is to use the invention to re-chain the chain, the two auxiliary wrenches have positioned the chain support, in order to overcome the preset elastic force applied by the transmission to the chain, we only need to hold the body with one hand and turn the wrench with the other hand. The rod can easily complete the re-packing work, so the invention can greatly improve the operation convenience of the existing chain tool set in the chain, and it can make us more comfortable.
