[0047] Working principle: The hydraulic rod 4 pushes the machine body 5 placed on the top of the base plate 1. When the machine body 5 enters the hole, when the front end encounters hard rock, the cutting resistance is large, which easily causes the risk of the machine body 5 warping and rotating.

By fixing the fixed pipe 2 10 at the lower end of the manual hoist 9 to the front and rear sides of the base plate 1, the entire iron chain 7 system can stably pull the tail of the machine body 5 and fix it on the base plate 1, ensuring that the machine body 5 can move and work smoothly under the pushing action of the hydraulic rod 4;

[0048] Moreover, when the machine body 5 is placed on the top right area of ​​the base plate 1, it will first contact the curved plate 205, and its weight will first act on the curved plate 205. The curved plate 205 is connected to the support plate 1 203 through the hinge 204, and can flexibly adapt to the placement action of the machine body 5. The pulley 206 in the middle of the rear side of the curved plate 205 enables the machine body 5 to slide to the appropriate position more smoothly, reducing friction. The multiple springs 202 fixedly connected to the bottom end of the groove 201 play a buffering role when the machine body 5 is placed, absorbing the impact force when the machine body 5 falls, and avoiding damage between the machine body 5 and the base plate 1 due to the instantaneous large impact force.
