The insertable hinge pin 8 is connected to the upper support 3 via a chain 10 so as not to be lost. A vertical guide groove 16 toward the center of the support hole 2 is formed in the center of the upper support 3, and a cutter 17 is slidably provided in the guide groove 16 in the vertical direction.

One end of each of the front oblique link 18 and the rear oblique link 19 is pivotally attached to the cutter 17, and one end of each of the front upright link 20 and the rear upright link 21 is pivotally attached to the upper support 3. The other end of the link 18 and the other end of the front standing link 20,
The other end of the rear oblique link 19 and the other end of the rear standing link 21 are pivotally connected. Handle with screw bar 27 protruding from gripping piece 26
The screw rod 27 is inserted through a pivotal connection portion 28 between the other end of the rear oblique link 19 and the other end of the rear upright link, and pivots between the other end of the front oblique link 18 and the other end of the front upright link 20. Screw it into the fitting part 29. Here, the screw rod 27 is simply inserted through the pivot portion 28 without being screwed, and is screwed at the pivot portion 29. Therefore, when the gripping piece 26 of the handle 30 is gripped and rotated in the right direction, the screw rod 27 and the pivoting part 29 are engraved on the right-hand screw.
Cutter 16 supported by 18 and rear oblique link 19
Descends and cuts the hose externally fitted to the joint pipe supported by the support hole 2 in the axial direction.

When the handle 30 is rotated to the left, the pivots 28 and 29 move away from each other, and the cutter 16 moves upward. A hose clamp 31 is provided below the support hole 2 of the lower support 4 so that hoses having different outer diameters can be clamped. The hose clamp 31 includes a clamp 32 and a handle 33.The upper end of the clamp 32 is formed on an arc surface 41 so as to be able to contact the outer surface of the hose, and the base end is formed on a nut portion 34, A screw hole 35 is formed in the center vertical direction. Handle 33 is a disc-shaped gripping piece 36
The screw rod 37 is projected from the
The handle 33 is rotatable and the gripping piece 36 is externally fitted to the proximal end side of the screw rod 37 so that the handle 33 cannot be moved forward and backward. Therefore, if the screw hole 37 of the screw rod 37 and the nut part 34 is formed in the left-hand thread, the clamp 32 rises when the gripping piece 36 of the handle 33 is turned clockwise, and conversely when the gripping piece 36 is turned counterclockwise.
32 descends, and the clamp 32 can be advanced and retracted according to the size of the outer diameter of the hose externally fitted to the joint pipe attached to the support hole 2. The upper end of the clamp 32 has an arc surface 41.
The guide hole 40 is formed so as to fit into the outer diameter of the nut part 34 because rotation of the hose hinders the support of the hose.

In the above embodiment, the support 1 is the upper support 3
When the hose externally fitted to the joint pipe is cut in the radial direction in advance with respect to the axis, and then the externally fitted hose is cut in the axial direction, It is not necessary to divide the support 1 up and down.
