[0008] Further, the round die includes a body, chip removal holes, and cutting teeth. The cutting teeth and the chip removal holes are located inside the body. At least two chip removal holes are provided inside the die body, and the chip removal holes are evenly arranged axially between every two cutting teeth.

[0009] Further, the number of the chip removal holes is six.

[0010] Further, one end of the sleeve is a rod body, and it forms a detachable connection structure with the quick automatic clamping chuck through the rod body.

[0011] Further, the nut is a hexagonal nut, and the sleeve is provided with a regular hexagonal inner hole adapted to the hexagonal nut.

[0012] Further, the drilling machine is a hand drill.

[0013] The advantages of the present utility model compared with the prior art are as follows: The device has a reasonable structural design and is convenient to use. By means of the sleeve, the drilling machine is connected to the threading mechanism. After starting the drilling machine and pressing down, rapid threading repair of the spike can be achieved, greatly improving the work efficiency; meanwhile, the time and cost of manual operation can be reduced.

[0020] The following further details a rapid threading device for spiral spikes of railway concrete sleepers according to the present utility model with reference to the accompanying drawings.

[0021] With reference to the accompanying drawings, a rapid threading device for spiral spikes of railway concrete sleepers includes a threading mechanism and a drilling machine 3. The threading mechanism includes a circular die 1 and a nut 2. One end of the circular die 1 is fixedly connected to one end of the nut 2. The circular die 1 is provided with a central through hole, and the central through hole is coaxially arranged with the screw hole 201 of the nut 2. The inner diameter of the central through hole of the circular die 1 is the same as the inner diameter of the screw hole 201.

[0022] The head end of the body of the drilling machine 3 is provided with a quick automatic clamping chuck, and a sleeve 301 corresponding to the nut 2 is fixed on the quick automatic clamping chuck. The drilling machine 3 is connected to the threading mechanism through the sleeve 301 to form a connection structure.

[0023] Preferably, as an embodiment of the present embodiment, the circular die 1 includes a body 101, chip removal holes 102, and cutting teeth 103. The cutting teeth 103 and the chip removal holes 102 are located inside the body 101. At least two chip removal holes 102 are provided inside the die body 101, and the chip removal holes 102 are uniformly arranged axially between every two cutting teeth 103.

[0024] Preferably, in this embodiment, the number of the chip removal holes 102 is six.
