Description

  The present invention relates to a holder removal tool used when removing a holder from a hose clamp.

  Conventionally, one of the common hose clamps is a clamp body formed by bending a long spring plate so that both ends intersect each other, and each end of the clamp body is outward. What has the bending part formed by bending is known. In this hose clamp, the two bent portions are brought close to each other to expand the diameter of the clamp body against the urging force in the reduced diameter direction, and the two bent portions are separated from each other by attaching a holder. The main body is loosely fitted to the hose, and the holder is removed from the two bent portions, so that the clamp main body is reduced in diameter to hold the hose tightly.

  By the way, since a large force is applied from both the bent portions to the inner side surfaces of the holder with the urging force in the diameter reducing direction of the clamp body in a state where the holders are mounted on the both bent portions. A large force is required to remove from the both bent portions with a tool such as pliers. Therefore, if the holder is pulled with a tool during the removal work, the hose clamp is also drawn to the operator side together with the holder, and the hose clamp is displaced from the correct tightening position of the hose in the middle of removing the holder. There is a problem.

  In order to avoid this, it is conceivable to remove the holder while the clamp body is pressed against the hose. For example, a holder removal tool disclosed in Patent Document 1 includes a plate-like tool main body, and a pair of bar-shaped handles gripped by an operator is provided on one end side of the tool main body from one end of the tool main body. On the other hand, a pair of clamping members that clamp the holder from both sides are provided on the other end side of the tool body so as to extend outward from the other end of the tool body. The tool body is provided with a coupling mechanism that couples the handles and the clamping members. The coupling mechanism brings the clamping members closer to each other and the handle side when the handles are moved closer to each other. On the other hand, when both the handles are separated from each other, both the holding members are separated from each other and moved to the opposite side of the both handles.

  A pressing member that presses the hose clamp against the hose is provided on the other end side of the tool body so as to extend outward from the other end of the tool body. Both holding members are positioned on both sides of the holder so as to extend radially outward, and the holding members are moved closer to each other while the clamp body is pressed against the hose by the pressing member. The holder is removed from the hose clamp by being clamped from one side and moving toward the both handles.
