Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

As shown in fig. 1 to 5, the structure of the pipe cutter of the present invention is illustrated. When the pipe cutting knife comprises a fixed handle 1, a movable handle 2 and a blade 3, the blade 3 is rotatably fixedly connected in the fixed handle 1 through a rotating shaft 4, the movable handle 2 is hinged with the fixed handle 1, the blade 3 is clamped, and when the movable handle 2 is pressed, the blade 3 is driven to rotate around the rotating shaft 4 in a reciprocating mode to cut a pipe body.

Specifically, the rotating shaft 4 includes a locking head 41, a cylindrical rod 42 integrally extending from the locking head 41, and a first latch mechanism 43 disposed at a distal end of the cylindrical rod 42, the cylindrical body 42 penetrates the fixed handle 1 and the blade 3, and the blade 3 is hinged to the fixed handle 1 through the locking head 41 and the first latch mechanism 43 at two ends.

More specifically, the first latch mechanism 43 includes a first mounting groove 431 opened at the end of the cylindrical rod 42, a first return spring 432 fixedly connected in the first mounting groove 431, and a first latch member 433 telescopically connected in the first mounting groove 431 by the first return spring 432, wherein when the first return spring 432 is in a normal state, the first latch member 433 is partially exposed out of the first mounting groove 431; when the cylindrical rod 42 passes through the fixed handle 1 and the blade 3, the first clamping piece 433 is extruded, and the first return spring 432 is compressed to drive the first clamping piece 433 to move downwards to be completely immersed into the first mounting groove 431, so that the cylindrical rod 42 can smoothly pass through the fixed handle 1 and the blade 3; after the cylindrical rod 42 with the first clamping assembly 43 passes through the fixed handle 1, the first return spring 432 tends to return to normal movement, and drives the first clamping member 433 to move upward and expose in the first mounting groove 431, and at this time, the locking head 41 and the first clamping member 433 are located at two ends of the fixed handle 1 to fix the blade 3 in the fixed handle. Accordingly, when the blade 3 is worn and needs to be replaced, the shaft 4 can be withdrawn by simply pressing the cylindrical rod 42 to separate the blade 3 from the fixed handle 1. It should be understood that the first clip member 43 of the present invention can be implemented as a ball, and can also be implemented as other structures, which is not limited by the present invention.

Furthermore, a tooth groove 31 is formed in the blade 3, a blade pushing device 21 and a blade locking device 22 are arranged on the movable handle 2, the blade pushing device 21 and the blade locking device 22 are clamped with the tooth groove 31, the blade pushing device 21 is used for controlling the rotation of the blade 3, the blade locking device 22 is used for fixing the position of the blade 3, the top end of the movable handle 2 is hinged to the fixed handle 1 through the blade locking device 22, and the blade pushing device 21 and the blade locking device 22 are matched with each other for use, so that an operator can cut the round pipe in a labor-saving manner.

More specifically, the rigid coupling has chamfer ware 8 in the activity handle 2, and chamfer ware 8 is located between activity handle 2 and the fixed handle 1, has seted up chamfer groove 81 in the chamfer ware 8, can deepen the pipe after tailorring between activity handle 2 and the fixed handle 1 to will tailor and lean on in chamfer groove 81 rotation, grind out a smooth chamfer with sharp incision through chamfer groove 81, thereby prevent that the staff from fish tail when operating.

Furthermore, the tail end of the movable handle 2 is hinged with a tail buckle 5, the tail end of the fixed handle is provided with a fixture block 6 matched with the tail buckle 5, when the pipe cutter is not needed to be used, the two handles can be pressed close to each other, and the tail buckle 5 and the fixture block 6 are clamped with each other to fix the fixed handle 1 and the movable handle 2.

Furthermore, the end of the movable handle 2 is further provided with a second clamping mechanism 7, the second clamping mechanism 7 comprises a second mounting groove 71 arranged at the end of the movable handle 2, a second return spring 72 fixedly connected in the second mounting groove 71, and a second clamping member 73 telescopically arranged in the second mounting groove 71 through the second return spring 72; when the second return spring 72 is in a normal state, part of the second clamping piece 73 is exposed out of the second mounting groove 71, correspondingly, the tail buckle 5 is provided with a clamping groove 51 matched with the second clamping piece 73, a notch of the clamping groove 51 is provided with an inclined chamfer, and when the tail buckle 5 is buckled to the fixture block 6, the second clamping piece 7 enters the clamping groove 51 along the chamfer of the clamping groove 51, so that the tail buckle 5 is driven to be automatically buckled into the fixture block 6 to complete clamping, and through the arrangement, an operator does not need to press the tail buckle 5 to the bottom and can realize automatic locking only by pressing to a certain position; simultaneously, when the activity handle 2 after the lock is locked and fixed handle 1 were pressed, second latch mechanism 7 can be fixed with tail-gate 5, prevents that it from dropping from 6 departments of fixture block and leading to the unable lock of activity handle 2 and fixed handle 1, avoids carrying out the secondary operation.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the technical principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
