Description

Technical Field

[0001] The utility model relates to the technical field of pipe shearing, in particular to a PVC pipe shearing device. Background Art

[0002] At present, in the construction industry, PVC pipes are widely used in the construction field as a kind of construction consumables. PVC pipes can be used as sewer pipes, lead pipes and water pipes, etc., because of their high stability and low price, they are deeply loved by people. When installing and constructing PVC pipes, it is necessary to cut the PVC pipes into different lengths according to different situations, and then connect the PVC pipes. The connection method usually adopts sealing rubber ring connection or bonding, and flange connection can also be used. These connection methods are to connect the PVC pipes into different structures according to the actual application scenarios to meet different space arrangements. However, the current PVC pipe cutting device mainly consists of a shear knife and a handle. The handle and the shear knife are connected to form a scissor fork structure. The PVC pipe is placed between the two shear knives, and a grip is applied to the handle to cut the PVC pipe into a flat end. The PVC pipe cut in this way is bonded. Because the contact surface is small and the bonding force is small, when the water pressure in the PVC pipe is too large, the bonding of the PVC pipe will be pulled apart, and the bonding is not firm; and the shearing device composed of scissors has a single function, which can usually only cut but not bond.

[0003] In the prior art, a Chinese patent with publication number CN203805010U discloses a pipe scissors with a buckle, which is composed of a fixed handle, a movable handle, a scissor mouth, a positioning tooth, a positioning rod and a buckle. The fixed handle and the movable handle are combined into a whole scissors piece, and the movable handle is fixed to the boss at the front end of the fixed handle by a movable pin. The front end of the movable handle is provided with a scissor mouth, and a buckle is provided at the scissor mouth. The inner end of the angle between the fixed handle and the movable handle is also provided with a positioning tooth and a positioning rod. In actual application, the pipe and the scissor device can be securely positioned according to the caliber of the processed pipe, so that the operator will not cause the pipe to slip or move when applying force to the scissors. Although the pipe scissors ensure the flatness of the pipe cut, due to the flatness of the pipe mouth, the contact area between the pipe mouths is small during bonding, and the bonding is not firm; and the pipe scissors have a single function, which can only cut but not bond.
