[0019] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0020] See also Figure 1 and Figure 2 The utility model provides a cutting device, which includes a holder 1 and a sleeve 2 connected thereto; wherein the structure of the sleeve 2 can be set as required, and can be an integrated structure as shown in the figure in this embodiment, of course, the sleeve 2 can also be set as a movable sleeve structure with a buckle 01 at the end for the convenience of placing the pipe 00 therein ( Figure 3 As shown in the embodiment, specifically, one end of the ferrule 2 is hinged to the base 1, and the other end is connected to the ferrule 2 through a buckle connection structure (when in use, open the buckle, place the pipe inside the ferrule 2, and finally close the buckle). There is a placement space for placing the pipe between the base 1 and the ferrule 2. Specifically, as shown in the embodiment, the cross-section of the placement space is the same circle as the pipe. When the device is in use, the pipe is placed in the placement space (in the embodiment, the pipe is inserted into the placement space), and then the ferrule 2 is rotated, and the cutter 3 cuts the pipe.
[0021] The holder 1 is provided with an obstacle avoidance groove 4 for observing the position of the cutter 3, and the cutter 3 is arranged in the obstacle avoidance groove 4. Through the obstacle avoidance groove 4, the operator can observe the positioning of the cutter 3 and the position of the pipe to be cut (generally a mark drawn with a pen), and according to the deviation distance of the cutter 3, appropriately adjust the position of the ferrule 2 to increase the accuracy of the equipment when cutting the pipe.
[0022] The cutter 3 can be a fixed structure or a movable structure as provided in the present embodiment, and the end of the cutter head can be switched between a state close to the center of the placement space or a state far away from the center of the placement space. By providing the cutter 3 as a movable structure, the installation of the pipe fittings can be facilitated to prevent the cutter 3 from blocking the pipe fittings. Specifically, the end of the cutter 3 is hingedly mounted in the obstacle avoidance groove 4; an angle limiting assembly for limiting the angle of the cutter 3 is provided in the ferrule 2. The angle limiting assembly includes a connecting portion 31 ( Figure 5 3 and a movable pull rod 32 hinged to the connecting portion 31. During use, the movable pull rod 32 moves to drive the hinge point of the cutter 3 to rotate, and further drives the cutter 3 to change its angle, so that it can switch between a state close to the center of the placement space or a state far from the center of the placement space. During the installation of the pipe fitting, the cutter 3 is far from the center of the placement space, and during the cutting process, the cutter 3 is close to the center of the placement space.
