DETAILED DESCRIPTION
[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.
[0021] like Figure 1 and 2As shown, the utility model discloses a tool for cutting PVC casing of wall screw hole, specifically, the tool comprises: a left cutting body 1, a right cutting body 2 and a hinge shaft 3; the left cutting body 1 and the right cutting body 2 are hinged by the hinge shaft 3; the left cutting body 1 comprises a left grip 11, a left handle body 12 and a left cutting blade head 13, the left cutting blade head 13 is connected with the left grip 11 through the left handle body 12, the left cutting blade head 13 comprises a left semicircular cutting plate 131 and a left cutting tooth 132 located on the arc-shaped outer circumference of the left semicircular cutting plate 131, and the left semicircular cutting plate 131 is arranged perpendicular to the left handle body 12; the right cutting body 2 comprises a right grip 21, a right handle body 22 and a right The right cutting blade head 23 is connected to the right handle 21 through the right handle body 22, and the right cutting blade head 23 includes a right semicircular cutting plate 231 and a right cutting tooth 232 located on the arc-shaped outer circumference of the right semicircular cutting plate 231. The right semicircular cutting plate 231 is arranged perpendicular to the right handle body 22, and the straight portion of the left semicircular cutting plate 131 and the straight portion of the right semicircular cutting plate 231 are arranged relatively to each other so that the left semicircular cutting plate 131 and the right semicircular cutting plate 231 roughly form a circular cutting plate when the handle bodies are closed, so as to facilitate the left semicircular cutting plate 131 and the right semicircular cutting plate 231 to be able to extend into the PVC sleeve to be cut for cutting operation.
[0022] Specifically, the left handle 11 and the right handle 21 are provided with finger gripping holes for easy finger gripping. The left cutting teeth 132 and the right cutting teeth 232 are both triangular structures, so that the cutting teeth are sharper and the connection between them and the semicircular cutting plate is more stable; the gap between the left handle 11 and the right handle 21 is gradually larger from the end close to the hinge shaft 3 to the end away from the hinge shaft 3 (when the tool is not in use), so when cutting the PVC sleeve, first extend the cutting head and the handle body into the PVC sleeve, and when the cutting head reaches the cutting position, hold the left handle 11 and the right handle 21 with fingers to make them close, then the left cutting head 13 and the right cutting head 23 are separated from each other until they are pressed against the PVC sleeve for cutting, so the tool can be applied to PVC sleeves of different diameters.
[0023] In the embodiment of the utility model, the left handle body 12 and the right handle body 22 are both square cylinders; the diameters of the left semicircular cutting plate 131 and the right semicircular cutting plate 231 are both 2.8 to 3.2 cm (e.g., 2.8 cm, 2.9 cm, 3 or 3.2 cm, etc.), which are smaller than the inner diameter of a general PVC sleeve to facilitate insertion into the PVC sleeve, and the length and width of the square cylinder are both less than or equal to the diameter of the semicircular cutting plate. The left cutting body 1 and the right cutting body 2 are both made of stainless steel. The lengths of the left grip 11 and the right grip 21 are both 75 to 85 mm (e.g., 75 mm, 76 mm, 80 mm or 85 mm, etc.).
[0024] When in use, insert the tool into the PVC casing, then hold the handle tightly so that the cutting teeth of the left cutting head and the right cutting head are clamped on the wall of the PVC casing, and then use the wrist to drive the handle to rotate so that the cutting teeth of the cutting head rotate in the pipe wall to achieve the cutting effect.
[0025] In summary, the utility model discloses a tool for cutting PVC sleeves in wall screw holes. The tool is applicable to PVC sleeves of different diameters, and due to its compact and convenient structure, it is not restricted by the site when used, and has strong practicality.
