Embodiment 1

[0018] A water pipe maintenance cutting tool, such as figure 1 , 2 As shown, it includes an upper arm 1, a lower arm 2, a first spring 3, a cut-off part and a labeling part. The first spring 3 is connected between them, the upper arm 1 and the left part of the lower arm 2 are provided with a cutting part for cutting off the water pipe by rotating, and the upper arm 1 is provided with a labeling part for marking by pushing.

[0019] Such as figure 1 , 2 As shown, the cut-off part includes a first rotating shaft 4, a blade 41, an arc rack 5, a second rotating shaft 6, a transmission gear 7, an overrunning clutch 8, a third rotating shaft 9 and a pinion 10, and the left side of the upper arm 1 The first rotating shaft 4 is rotatably connected to the top of the first rotating shaft 4, and a blade 41 is connected with a key on the first rotating shaft 4. The right side of the blade 41 is welded with an arc rack 5, and the upper arm 1 on the right side of the arc rack 5 is rotata...

Embodiment 2

[0025] Such as figure 1 , 2 As shown, on the basis of Embodiment 1, in order to use the device more labor-saving, it also includes a reset gear 19 and a runner 20, and the upper arm 1 on the right side of the arc rack 5 is rotatably connected with a reset gear 19. Gear 19 meshes with arc rack 5, and the rotating part of reset gear 19 passes upper arm 1 and is connected with running wheel 20, and reset gear 19 radius is 1 / 3rd of arc rack 5 radius.

[0026] Such as figure 1 , 3 As shown, in order to prevent water from splashing to the maintenance personnel, it also includes a slider 22, a block 23, a second spring 24, a connecting rod 25 and a baffle 27, and two slide slots 21 are opened on the front and rear sides of the left part of the upper arm 1. , the two chute 21 are symmetrical up and down, the chute 21 is slidably connected with the slider 22, the inner side of the slider 22 is welded with the block 23, the second spring 24 is welded between the slider 22 and the upp...

Abstract

The invention relates to a cutting tool, in particular to a water pipe maintenance cutoff tool. The technical problem to be solved is how to provide a water pipe maintenance cutoff tool with a markingfunction and capable of preventing water from splashing on maintenance personnel. The water pipe maintenance cutoff tool comprises an upper arm, a lower arm, a first spring, a cutoff component, a marking component and the like; the left part of the upper arm is rotatably connected with the left part of the lower arm, the lower arm is arranged on the outer side of the upper arm, the first spring is connected between the left part of the upper arm and the left part of the lower arm, and the left part of the upper arm and the left part of the lower arm are provided with the cutoff component forcutting off water pipes in a rotating mode. The marking component is arranged, the cut position can be marked through the marking component, so that the device has a marking function, the practicability of the device is improved, meanwhile, water pipes can be more accurately cut off, the cutting device can cut off the water pipes in a quite labor-saving manner, and because a reset gear is smallerthan an arc-shaped rack, a blade can be reset in a more labor-saving manner.

Description

technical field [0001] The invention relates to a cutting tool, in particular to a cutting tool for water pipe maintenance. Background technique [0002] Water pipes are water supply pipes. Modern decoration water pipes are built with buried walls. There are three types of water pipes. The first type is metal pipes, such as hot-dip cast iron pipes with plastic lining, copper pipes, and stainless steel pipes. The second category is plastic composite metal pipes, such as plastic composite steel pipes, aluminum-plastic composite pipes, etc. The third category is plastic pipes, such as PB, PP-R, etc. Water pipe maintenance needs to cut off the broken part of the water pipe, which can save materials and save maintenance time. [0003] Now when cutting the damaged water pipe, the maintenance personnel use the water pipe cutter to cut it off. Before cutting the water pipe, it is necessary to mark the cut-off place, which can improve the accuracy of the water pipe cutting. Now it ...
