AI Technical Summary
Existing logging tools are time-consuming and labor-intensive, bulky, inconvenient to carry and poor operational safety in operation. Especially when cutting trees with large diameters, loggers have greater labor intensity.
A logging auxiliary chain is designed, with hanging rings fixed at both ends of the chain, a detachable fixing bracket in the middle, and a steel chain fixed at the lower end of the bracket, which is used to mount logging tools. The chain is simple in structure, light in weight and easy to carry. The chain is tightened by a ratchet tensioner. The logging tool is hung in the air and the workers only need to cut it hard.
This logging auxiliary chain greatly reduces the labor intensity of loggers, improves logging efficiency, reduces operational difficulty and safety risks, and is easy to carry.

Abstract
Description
Technical Field
[0001] The utility model belongs to a felling auxiliary device, in particular to a felling auxiliary chain. Background Art
[0002] In the process of landscaping construction and maintenance, it is often necessary to renew and cut down sick and old trees. Under existing technical conditions, logging tools mainly include hand saws, electric saws, and chain saws. However, practice has shown that hand saws are time-consuming and labor-intensive to operate, and have low logging efficiency. Electric saws and chain saws are both bulky, inconvenient to carry, and have poor operating safety.
[0003] During forest felling, if the diameter of the trees being felled is larger, larger logging tools are required. The logging tools are heavier, and the labor intensity of the loggers is greater. Summary of the invention
[0004] In order to overcome the shortcomings of the prior art, the utility model provides a felling auxiliary chain, which has a simple structure, light weight, and is easy to carry, thus greatly reducing the labor intensity of the fellers.
[0005] The utility model solves the technical problem by adopting the following technical scheme: hanging rings are respectively fixed at both ends of the chain, a detachable fixing bracket is provided in the middle of the chain, a steel chain is fixed at the outer lower end of the bracket, and logging tools can be hung on the steel chain.
[0006] The utility model has the advantages of simple structure, light weight and convenient carrying, and can greatly reduce the labor intensity of the woodcutters. BRIEF DESCRIPTION OF THE DRAWINGS
[0007] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0008] Figure 1 This is the front view of the utility model;
[0009] Figure 2 It is a top view of the utility model. DETAILED DESCRIPTION
[0010] like Figure 1 , 2 As shown, hanging rings 1 are fixed at both ends of the chain 2, a detachable fixed bracket 3 is fixed on the chain shaft in the middle of the outer side of the chain 2, a steel chain 4 is fixed at the outer lower end of the bracket 3, and a logging tool (not shown) can be hung on the steel chain 4.
[0011] The utility model also comprises a ratchet type tensioner (commercially available), one hook of the ratchet type tensioner hangs on the hanging ring 1, and the other hook hangs on the chain 2.
[0012] The chain 2 can be replaced by a steel chain.
[0013] In order to increase the tree gripping ability of the chain 2, a pointed protrusion 5 is provided on the inner chain plate of the chain 2.
[0014] When in use, the chain 2 is wound around the appropriate position above the cut of the tree to be felled, the inner side of the chain 2 is close to the tree, one hook of the ratchet tensioner is hung on the hanging ring 1, and the other hook is hung on the chain 2. According to the diameter of the tree to be felled, the chain 2 is manually tightened as much as possible. Turn the handle of the ratchet tensioner to tighten the chain 2. Hang the felling tool on the appropriate position of the steel chain 4, so that the felling tool is aligned with the cut of the tree. In this way, the felling tool is suspended in the air, and there is no need to hold it manually. The lumberjack only needs to cut with force. The cut is accurate and the labor intensity is low.
