[0002] During the production and processing of fabrics, the edge positions of the fabrics need to be cut, and the cutting tool plays an important role in the cutting process.

[0003] However, there are some deficiencies in the current cutting tools. The lengths of the cutting tools are fixed. Therefore, in order to meet the needs of cutting, the tools need to be replaced, so as to use cutting tools of different lengths for cutting. However, this is rather troublesome and reduces the practicability of the cutting tools. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a cutting tool for an automatic edge cutting machine for fabric edges, which can effectively solve the problems in the background art.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A cutting tool for an automatic edge cutting machine for fabric edges, comprising a first tool body, a second tool body and a bolt and nut assembly. One end of the second tool body is internally embedded with a bolt and nut assembly. One end of the first tool body is embedded with a threaded stopper below, and a limiting member is fixedly installed on the surface of the other end of the first tool body.

[0007] Preferably, a plug board is fixedly installed on the surface of one end of the first tool body. A fixing block is fixedly installed on the surface of one end of the first tool body and at the rear. An internal threaded column is fixedly installed on the lower surface of the fixing block. The upper end of the threaded stopper is embedded inside the internal threaded column.

[0008] Preferably, a jack is opened on the upper surface of one end of the second tool body. A docking groove is opened inside one end of the second tool body. A sleeve is fixedly installed on the surface of one end of the second tool body and at the rear.

[0009] Preferably, the jack penetrates through the docking groove. Mounting holes are opened on the upper surfaces of the first tool body, the second tool body and the plug board. The plug board is embedded in the docking groove. The bolt and nut assembly penetrates through the jack and the mounting hole of the plug board.

[0010] Preferably, the sleeve is sleeved on the surface of the internal threaded column. The diameter of the fixing block is larger than the diameter of the internal threaded column.

[0011] Preferably, the limiting member includes a mounting block, a moving bar and a limiting slider. An installation groove is formed inside the mounting block, and limiting sliding grooves are formed on the upper surface and the lower surface inside the installation groove. Limiting sliders are fixedly installed on the upper surface and the lower surface at the rear end of the moving bar.

[0012] Preferably, the moving bar is movably installed in the installation groove, the limiting slider is embedded in the limiting sliding groove, and the limiting member is fixed to the first cutter body through the mounting block.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] In the utility model, by setting the first cutter body, the second cutter body, the bolt-nut assembly, the limiting block and the threaded stop member to cooperate with each other, when it is necessary to shorten the length of the cutting tool, only the bolt-nut assembly needs to be disassembled, and then the second cutter body can be folded. After the second cutter body is attached to the first cutter body, move the moving bar of the limiting member so that the moving bar moves out of the installation groove of the mounting block. After moving out, the moving bar contacts the second cutter body. Since the moving bar has a certain length, the moving bar can prevent the second cutter body from flipping and moving, so that the folded second cutter body can be limited, and at this time the length of the cutting tool is shortened.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] To make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] As Figures 1-4 shown, a cutting tool for an automatic edge cutting machine of a fabric selvage includes a first knife body 1, a second knife body 2 and a bolt and nut assembly 3. A bolt and nut assembly 3 is embedded inside one end of the second knife body 2. A threaded stop member 5 is embedded below one end of the first knife body 1. A limiting member 4 is fixedly installed on the surface of the other end of the first knife body 1.

[0022] A plug board 101 is fixedly installed on the surface of one end of the first knife body 1. A fixing block 103 is fixedly installed on the surface of one end of the first knife body 1 and located at the rear. An internal threaded column 104 is fixedly installed on the lower surface of the fixing block 103. The upper end of the threaded stop member 5 is embedded inside the internal threaded column 104. The cooperation between the threaded stop member 5 and the internal threaded column 104 can keep the sleeve 201 sleeved on the surface of the internal threaded column 104. A jack 202 is opened on the upper surface of one end of the second knife body 2. A docking groove 203 is opened inside one end of the second knife body 2. A sleeve 201 is fixedly installed on the surface of one end of the second knife body 2 and located at the rear. The jack 202 penetrates through the docking groove 203. Mounting holes 102 are opened on the upper surfaces of the first knife body 1, the second knife body 2 and the plug board 101. The plug board 101 is embedded in the docking groove 203. The bolt and nut assembly 3 penetrates through the jack 202 and the mounting hole 102 of the plug board 101. The threaded nut assembly 3 can firmly connect the first knife body 1 and the second knife body 2 together. The sleeve 201 is sleeved on the surface of the internal threaded column 104. The diameter of the fixing block 103 is greater than that of the internal threaded column 104. The limiting member 4 includes a mounting block 401, a moving strip 402 and a limiting slider 405. An installation groove 403 is opened inside the mounting block 401. Limiting sliding grooves 404 are opened on the upper surface and the lower surface inside the installation groove 403. Limiting sliders 405 are fixedly installed on the upper surface and the lower surface at the rear end of the moving strip 402. When the second knife body 1 and the first knife body 2 are folded, the moving strip 402 is pushed to make the moving strip 402 move out of the installation groove 403, so as to prevent the second knife body 2 from flipping. The moving strip 402 is movably installed in the installation groove 403. The limiting slider 405 is embedded in the limiting sliding groove 404. The limiting member 4 is fixed to the first knife body 1 through the mounting block 401.

[0023] It should be noted that the present utility model is a cutting tool for an automatic edge trimming machine of a fabric selvage. When in use, when it is necessary to shorten the length of the cutting tool, only the bolt and nut assembly 3 needs to be disassembled, and then the second tool body 2 can be folded. After the second tool body 2 fits with the first tool body 1, move the moving strip 402 of the limiting member 4 so that the moving strip 402 moves out of the mounting groove 403 of the mounting block 401. The moved moving strip 402 contacts the second tool body 2. Since the moving strip 402 has a certain length, the moving strip 402 can prevent the second tool body 2 from flipping and moving, so that the folded second tool body 2 can be limited. At this time, the length of the cutting tool is shortened, and there is no need to replace a cutting tool with a shorter length to meet the cutting requirements.
