Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Referring to fig. 1 and fig. 2 and fig. 3, an embodiment of the present invention provides a fixing device for plunger drilling, including a base 1, a flange 101 cast at a lower end of the base 1, bearing mechanisms 2 welded at both sides of an upper end of the flange 101, three guide posts 102 welded at an upper end of the base 1, clamping rods 3 sleeved on the three guide posts 102, a top base 4 sleeved on the upper ends of the three guide posts 102, a collar 401 cast at an outer side of the top base 4, a clamping seat mechanism 5 clamped on the collar 401, a set screw 6 threaded between the clamping seat mechanism 5 and the collar 401, three connecting rods 7 rotatably installed at a lower end of the clamping seat mechanism 5 through pins, and the three connecting rods 7 rotatably connected with the three clamping rods 3 through pins respectively.

Referring to fig. 3 and 4, the left and right ends of the base 1 are both provided with support holes 103, and the front and rear sides of the two support holes 103 are both provided with movable holes 104 for inserting the bearing mechanism 2.
