Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

A fixing base of the present invention will be described in detail with reference to fig. 1 to 5: a fixing seat 1 comprises a fixing seat 1, wherein a cavity 2 is arranged inside the fixing seat 1, a mounting hole 3 communicated with the cavity 2 is formed in the front end face of the fixing seat 1, a through hole 4 communicated with the cavity 2 is formed in the upper end face of the fixing seat 1, and a first limiting hole 5 is formed in the rear end face of the fixing seat 1;

the clamping piece 6 is arranged in the cavity 2, the clamping piece 6 is integrally formed by an arc-shaped clamping portion 7 and a control rod 8, the control rod 8 is arranged in the through hole 4, the cross section of the control rod 8 is consistent with that of the through hole 4, a second limiting hole 9 is dug in the rear end face of the clamping portion 7, and the first limiting hole 5 is consistent with that of the second limiting hole 9 in shape and size.

The mounting hole 3, the first limiting hole 5 and the second limiting hole 9 are all circular holes; the upper end face of the control rod 8 is provided with a clamping piece 10; the side surface of the fixed seat 1 is provided with an installation part 11, the upper end surface and the lower end surface of the installation part 11 are both provided with a circular groove 12, and the inner wall of the groove 12 is an inclined surface; the lower end face of the clamping part 7 is provided with a cushion pad 13; a sheath 14 is arranged on the inner side of the mounting hole 3, and the sheath 14 and the fixed seat 1 are of a separated structure.

The working principle is as follows: one end of the cutter bar extends into the cavity 2 of the fixing seat 1 through the mounting hole 3, then the clamping piece 6 is pushed downwards to the position where the first limiting hole 5 is aligned with the second limiting hole 9 through the control rod 8, the cutter bar is clamped by the clamping part 7 at the moment, and finally the bolt is inserted into the first limiting hole 5 and the second limiting hole 9 to complete the fixation of the cutter bar.
