Problems solved by technology

[0003] Such as the Chinese patent "rotary cutter for cutting large-diameter tubes" whose patent No. is 200720109332.9, its defect is to adopt manual operation, it is more laborious to cut, the structure is also more complicated, the volume is large, heavy, and the cost is high, so it needs to be further developed. Improved Design
[0004] For example, the Chinese patent with the patent number 200720110120.2 "The pliers-type PVC pipe cutter with a fast and automatic knife retraction structure also has similar problems. It needs manual operation, and it is laborious to cut. The structure is complicated and the cost is high, especially the knife retraction mechanism is not enough. Compact and reasonable, needs further improvement

Embodiment Construction

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0031] Such as figure 1 As shown in -8, a plastic pipe cutter tool includes a casing with a handle. The casing is divided into a left casing 1 and a right casing 24. The left and right casings are combined and fixed with screws to form a casing. Shell, the upper part of the case is in the shape of a jaw, the middle and upper part is an expansion-shaped installation cavity 25, which is used to install the main components such as the motor 21, the transmission speed change mechanism, and the knife holder 28, and the middle and lower part of the case is a generally arc-shaped handle 26. The handle 26 is mainly a battery cavity 27, the battery cavity 27 is used to install multiple rechargeable batteries as the power supply part 22, the end of the handle 26 is arranged with a charging socket 23, and the charging circuit is formed by connecting wire...

Abstract

The invention provides a quick retracting device in a plastic tube cutting tool. The device is characterized in that: the last gear of a transmission shifting mechanism in the electric cutter tool is a clutch gear, and is sleeved on a gear shaft and provided with a clutch spring capable of sliding the clutch gear left and right; correspondingly, the surface of a machine shell is provided with a button hole inside which a return button and a button spring are arranged; simultaneously, the side part of the return button is directly or indirectly contacted with the side surface of the clutch gear; when the return button is pressed down, the clutch gear is separated from the return button to be engaged with the local gear on the tail part of a cutter blade; and when the return button is released, the clutch gear is in engaged connection with the local gear on the tail part of the cutter blade, and the cutter blade is provided with a return elastic element capable of resetting the cutter blade. The device has the advantages of simple, practical and compact structure, small volume, and the realization of quick retraction of the cutter tool.

Description

technical field [0001] The invention relates to a cutting tool, in particular to a cutting tool for cutting PVC plastic pipes, aluminum-plastic composite pipes, or a knife retracting device in a device. Background technique [0002] With the continuous advancement of science and technology, various plastic pipes and aluminum-plastic composite pipes continue to enter the work and life of the majority of people. In the process of using plastic pipes such as PVC plastic pipes, it is often necessary to use a cutter to cut plastic pipes. Make it reach the required length, for this reason a lot of scientific and technical personnel are constantly developed new cutters or cutters that are suitable for cutting plastic pipes. [0003] Such as the Chinese patent "rotary cutter for cutting large-diameter tubes" whose patent No. is 200720109332.9, its defect is to adopt manual operation, it is more laborious to cut, the structure is also more complicated, the volume is large, heavy, and...
