The second embodiment of the present invention will be explained below.
During the cutting process of the blade 115, a user can directly use fingers to dial the fine adjustment handwheel 118A, so that the fine adjustment handwheel 118A rotates, the drive screw 119A advances and presses the push piece 1181A to advance, and the blade 115 advances forward, so that the cutting depth of the blade 115 is increased. When the user apparently feels that the blade 115 encounters a greater resistance, the fine adjustment handwheel 118A may be rotated in the opposite direction, causing the blade 115 to retract a portion.
Because the cutting depth of the blade 115 can be continuously finely adjusted along with the change of the cutting depth, the applicability is better, the cutting speed is higher, and the blade can be prevented from being broken due to overlarge resistance.
As shown in fig. 17 to 23, which are a third embodiment of the present invention, only a partial structure is shown here. Different from the first embodiment, a through spindle screw hole 50B is formed in the center of the spindle 5B, a through fine tuning window 501B is formed on a side wall of the head of the spindle 5B, a fine tuning long screw 54B is disposed in the spindle screw hole 50B, a first tapered head 542B is disposed at the head of the fine tuning long screw 54B, and a dial rod 541B is disposed at the tail of the fine tuning long screw 54B.
In addition, the cutter assembly 11B includes a pair of elongated tool holders 111A, a guiding semicircular groove 115B is further disposed on an inner wall of the tool holder 111B, a slidable driving bracket 120B is disposed on the guiding semicircular groove 115B, the driving bracket 120B includes a rod-shaped driving polish rod 121B, a sheet-shaped collet 123B is disposed at a head of the driving polish rod 121B, a collet opening 124B is disposed on a front side wall of the collet 123B, a size of the collet opening 124B is adapted to a thickness of the blade 115, a tapered second taper head 122B is disposed at a tail of the driving polish rod 121B, and the second taper head 122B is matched with the first taper head 542B.
The third embodiment of the invention will be explained below
As shown in fig. 24 and 25, during the cutting process of the blade 115, the user can directly use a finger to dial the dial rod 541B, so that the fine adjustment long screw 54B rotates downward, for example, in the direction of F1. The first conical head 542B of the fine adjustment long screw 54B directly presses against the second conical head 122B of the driving polished rod 121B below, so that the driving polished rod 121B translates along the direction F2, and at the same time, the collet 123B of the driving bracket 120B pushes the blade 115 to translate along the direction F2, so that the cutting depth of the blade 115 is increased. When the user feels significantly that the blade 115 encounters a greater resistance, the tap lever 541B may be rotated in the opposite direction, causing the blade 115 to retract a portion.
By utilizing the fine adjustment structure positioned at the tail part of the main rotating shaft 5B, a user can finely adjust the cutting depth of the blade 115 at any time, hands do not need to extend into the pipe body, and the operation is convenient.
Without being limited thereto, any changes or substitutions that are not thought of through the inventive work should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope defined by the claims.
