[0076] Embodiment 2

[0077] A manufacturing method of a pile head circumcision device, using the pile head circumcision device described in Embodiment 1, the method includes the following steps:

[0078] S1. Fabrication of the operation frame: As Figure 1 shown, all connecting rods and support rods are connected together by welding. When welding the rear end, the adjusting rod is sleeved on the vertical steel bar in advance and fixed at 20 cm from the rear end. After the main frame is installed, the remaining adjusting rods are connected as Figure 3 shown, and the other end is connected to the sleeve, so that the sleeve is always in a horizontal plane; the baffle is installed at the front end of the operation frame, and the fabrication of the operation frame is completed.

[0079] S2. Installation of the operating rod: The operating rod passes through the ring on the support rod and is welded to the top surface of the sleeve, and the steel pipe is welded to the top end of the operating rod as the handrail, and the installation of the operating rod is completed.

[0080] S3.
