  From here, the operation | movement of the saver saw 1 at the time of the cutting | disconnection operation | work of the to-be-cut material (for example, metal pipe) using the saver saw 1 in this Embodiment and a cutting operation is demonstrated, referring FIG. 8 thru | or FIG.

  When performing the cutting operation, the operator mounts the blade Q on the blade mounting portion 7 and presses the base 23B against the material to be cut. In this state, when the pulling operation is performed on the trigger 22A, the control unit of the control box 51 controls the six FETs 42, the electric power of the battery pack P is supplied to the motor 3, and the motor 3 starts driving. When the motor 3 starts driving, the rotating shaft portion 31 and the pinion 32 rotate, and the bevel gear 61 that meshes with the pinion 32 rotates around the rotating shaft that extends in the vertical direction. By the rotation of the bevel gear 61, the pin 62 performs a revolving motion around the rotation axis of the bevel gear 61 on a surface perpendicular to the vertical direction. Only the longitudinal component of the revolving motion of the pin 62 is transmitted to the pin guide 64, and the pin guide 64, plunger 63, blade mounting portion 7, and blade Q mounted on the blade mounting portion 7 reciprocate back and forth. Then, a material to be cut (not shown) is cut by the blade Q that reciprocates.

  Here, the pin guide 64, the plunger 63, the blade mounting portion 7, and the action of the first vibration isolation portion 8 during the operation in which the blade Q mounted on the blade mounting portion 7 reciprocates, and the second vibration isolation. The operation of the unit 9 will be described separately.

  First, the operation of the first vibration isolator 8 during work will be described.

  As the blade mounting portion 7 reciprocates in the front-rear direction, the cylindrical portion 211 of the motor housing 21 receives a force in the front-rear direction and reciprocates in the front-rear direction.

  When the blade mounting portion 7 moves forward, the cylindrical portion 211 of the motor housing 21 receives a rearward force and moves backward. At this time, as shown in FIG. 10, the cushion 83 disposed at the front portion of the inserted portion 82 is sandwiched between the boss 81 and the inner wall of the inserted portion 82 to absorb the impact, Suppressing the vibration caused by the reciprocating motion to the operator.

  Similarly, when moving to the rear of the blade mounting portion 7, the cylindrical portion 211 of the motor housing 21 receives a forward force and moves forward. At this time, the cushion 83 disposed at the rear portion of the insertion portion 82 is sandwiched between the boss 81 and the inner wall of the insertion portion 82, thereby absorbing the impact and transmitting the vibration due to the reciprocating motion to the operator. To suppress.

  Next, the operation of the second vibration isolator 9 during work will be described.

  As in the case of the first vibration isolator 8, in the front-rear direction, the second extending portion 213 of the motor housing 21 receives a force in the front-rear direction as the blade mounting portion 7 reciprocates in the front-rear direction. Reciprocate.

  When the blade mounting portion 7 moves forward, the second extending portion 213 of the motor housing 21 receives a force in the rear and moves rearward. At this time, the cushion 93 disposed at the front portion of the housing support portion 92 is sandwiched between the contact surface 925A of the first connection wall 925 and the front surface 911A of the main body portion 911 of the supported portion 91, thereby causing an impact. Absorbs and suppresses transmission of vibration due to reciprocating motion to the operator.

  Similarly, when the blade mounting portion 7 moves rearward, the second extending portion 213 of the motor housing 21 receives forward force and moves forward. At this time, the cushion 93 disposed at the rear portion of the accommodation support portion 92 is sandwiched between the contact surface 926A of the second connection wall 926 and the rear surface 911B of the main body portion 911 of the supported portion 91, thereby absorbing the impact. In addition, the vibration due to the reciprocating motion is prevented from being transmitted to the worker.

  Next, a case where an impact in the vertical direction is applied to the saver saw 1 (for example, when the saver saw 1 is dropped on the floor during work or hits against a wall or the like) will be described.

  First, a case where an impact is applied to the saver saw 1 and the motor housing 21 moves upward with respect to the handle housing 22 will be described.

For this reason, when an impact occurs in the vertical direction, when the motor housing 21 moves upward with respect to the handle housing 22, the upper surface 911 E of the main body 911 is in contact with the main body abutment surface of the first extension wall 921. The upper surface 912B of the projecting portion 912 contacts the projecting portion abutting surface 921C of the first extending wall 921 substantially simultaneously with the abutting on the 921E. Therefore, it is possible to receive an impact in the vertical direction by the main body contact surface 921E and the protrusion contact surface 921C, and the protrusion contact surface 921C is also compared to the case where the impact is received only by the main body contact surface 921E. Since it is possible to receive an impact, it is possible to disperse the stress due to the impact in the vertical direction.

  Next, a case where an impact is applied to the saver saw 1 and the motor housing 21 moves downward with respect to the handle housing 22 will be described.

Therefore, the main body contact surface 923A, the main body contact surface 924A, and the protrusion contact surface 922A can receive an impact in the vertical direction, and only the main body contact surface 923A and the main body contact surface 924A can receive the impact. Compared with the case of receiving an impact, the protrusion contact surface 922A can also receive an impact, so that the stress due to the impact in the vertical direction can be dispersed.

  Further, a case where an impact is applied to the motor housing 21 so that the motor housing 21 rotates with respect to the handle housing 22 around the rotation shaft portion 31 of the motor 3 will be described.

  For example, when an impact is applied to the saver saw 1 such that the motor housing 21 rotates clockwise relative to the handle housing 22, the upper surface 911E, the front lower surface 911G, and the rear lower surface of the main body 911 of the supported portion 91 are applied. 911H, the upper surface 912B and the lower surface 912C of the protrusion 912 are the main body contact surface 921E and the protrusion contact surface 921C of the first extension wall 921 of the housing support 92, and the protrusion of the second extension wall 922. The contact surface 922 </ b> A, the main body contact surface 923 </ b> A of the third extension wall 923, and the main body contact surface 924 </ b> A of the fourth extension wall 924 are inclined.

  The upper surface 911E, the front lower surface 911G, and the rear lower surface 911H of the main body portion 911 protrude substantially simultaneously with the contact with the main body contact surfaces 921E, 923A, and 924A of the first extension wall 921 of the housing support portion 92, respectively. The upper surface 912B and the lower surface 912C of the portion 912 are in contact with the protruding portion abutting surface 921C of the first extending wall 921 and the protruding portion abutting surface 922A of the second extending wall 922, respectively. Therefore, in addition to the main body contact surfaces 921E, 923A, and 924A, it is possible to receive an impact by the protruding portion contact surface 922A. It is possible to disperse stress due to impact.
