[0006] As a further improvement of the utility model, a plurality of through holes are arranged on the limiting sleeve along the circumferential direction.

[0007] As a further improvement of the utility model, the connecting assembly includes a screw rod and a fastening nut; the screw rod is fixedly mounted on the right end fixing plate, the left end of the screw rod movably passes through the left end fixing plate, and the fastening nut is mounted on the screw rod and locked.

[0008] As a further improvement of the utility model, the connecting assembly also includes a guide rod, one end of the guide rod is fixedly mounted on the right end fixing plate, and the other end of the guide rod movably passes through the left end fixing plate.

[0009] As a further improvement of the utility model, a supporting foot is fixedly provided at the lower end of the connecting plate.

[0010] As a further improvement of the utility model, the fixed plate includes an upper plate and a lower plate, the upper end surface of the lower plate is provided with a limiting hole, the lower end surface of the upper plate is provided with a limiting rod, the limiting rod passes through the limiting hole; and the side wall of the lower plate is provided with a positioning hole communicating with the limiting hole, a positioning pin is installed in the positioning hole, and the limiting rod is provided with a plurality of adjustment holes along the axial direction, and the positioning pin is inserted into the adjusting hole for positioning.

[0011] Compared with the prior art, the advantages of the present invention are:

[0012] 1. The utility model sets a limiting sleeve on the fixing plate, and the two ends of the axle are installed in the limiting sleeve, and then the fixing plate can be driven to move toward each other through the connecting component to achieve the purpose of clamping the axle. At the same time, the limiting sleeve is a tapered sleeve. The tapered setting not only facilitates the installation and clamping of axles of different sizes, but also the contact area between the tapered sleeve and the axle is small, which will not affect the uniform heating of the axle, thereby ensuring that the axle is evenly heated.

[0013] 2. The utility model sets a through hole in the limiting sleeve. The setting of the through hole can reduce the contact area with the axle without affecting the normal clamping of the axle, making it more convenient for the axle to be heated normally.

[0014] 3. The fixed plate of the utility model is divided into an upper plate and a lower plate, and a limit hole and a limit rod are provided at the same time. The coordination between the locating pin, the locating hole and the adjusting hole can adjust the spacing between the upper plate and the lower plate, thereby increasing the spacing between the axles, and better performing the heating treatment in the heat treatment box.
