Detailed Description
The embodiments of the present invention will be further explained with reference to the drawings.
Example (b):
as shown in fig. 1-3, the clamp spring type connection reaming sleeve comprises a reaming trephine 1, a pipe shoe 2 is sleeved on the outer surface of the reaming trephine 1, and a clamp spring 7 is sleeved between the outer surface of the reaming trephine 1 and the inner wall of the pipe shoe 2.
The working principle of the above technical scheme is as follows:
when the device is normally used, the device is formed by connecting a reaming trephine 1, a pipe shoe 2 and a clamp spring 7, the pipe shoe 2 can be assembled by a press machine after being independently tempered, the arrangement of the connecting structure greatly improves the production efficiency, simultaneously improves the hardness and the strength of the pipe boot, improves the wear resistance and prolongs the service life.
In another embodiment, as shown in fig. 1, the top surface of the trephine 1 is provided with a connecting groove 3 penetrating through the whole, and the outer surface and the inner wall of the top end of the trephine 1 are both provided with a polishing head 4.
When the device is normally used, the connecting groove 3 is sleeved at the driving end of a drilling tool for use, and the polishing head 4 is attached to a position needing drilling.
In another embodiment, as shown in fig. 3, the drill bit 101, the connection head 102 and the fixing head 103 form a reamer 1, the drill bit 101 is located at the top, the fixing head 103 is located at the bottom of the reamer, the connection head 102 is fixedly connected between the drill bit 101 and the fixing head 103, and the outer diameter of the connection head 102 is smaller than the outer diameters of the fixing head 103 and the drill bit 101.
