A structure for preventing the formation of a dead point for a cam wheel includes a driving wheel with a pressing portion provided at one side thereof for pushing a pushed portion of the cam wheel. When the cam wheel is moved over a distance while rotating simultaneously, a cam portion of the cam wheel pushes one end of the swinging piece. When the one end of the swinging piece is pushed to be apart from the outer periphery of the cam wheel, a restoring piece axially pushes the cam wheel back to its original position. A strapping device includes the above structure, a housing, a first transmission assembly, a second transmission assembly and a third transmission assembly. Tensioning of a circular strap, rapid friction bonding and cutting are sequentially performed by the transmissions of the first to third assemblies, respectively.

A cable tie tensioning and severing tool includes: a cutting member, a pulling member with a pivotable pushing block abutting against the cutting member, a trigger with a stop block abutting against the pushing block, a pivotable pressing hammer, a turning knob, and an elastic member compressed between the pressing hammer and a spirally ramped end face of the turning knob such that the pressing hammer applies to the cutting member a pressing force whose magnitude can be adjusted by rotating the turning knob. The stop block can be driven by the trigger to push the pushing block, which in turn pulls a cable tie through the pulling member and, once the pressing force is overcome, pivots the cutting member to sever the cable tie.

A strapping machine of the type that feeds, retracts, tensions and seals strap to itself to form a loop of strap around a load, has a shock absorbing feed wheel assembly. The machine includes a frame, a feed head having a motor, a tension head, a sealing head and a strap chute mounted to the frame. The feed wheel assembly has a friction engaging surface and at least one pocket formed therein. A spring hub is engaged with the feed wheel and has at least one pocket formed therein corresponding to the feed wheel pocket. The spring hub is operably connected to the feed head motor. At least one spring is positioned in the feed wheel pocket and the spring hub pocket and is sandwiched between the feed wheel and the spring hub. The feed wheel is driven by rotation of the spring hub and engagement of the spring with the feed wheel pocket and spring hub pocket. The shock absorbing feed wheel assembly dampens the forces on the feed head motor and drive when the feed wheel comes to an abrupt stop and prevents strap slippage.

A binding machine for gardening includes a main handle to draw out a tape, a clincher arm rotatably attached to the main handle, and a tape gripping device attached to the clincher arm. When the clincher arm rotates in a closing direction to a predetermined position with respect to the main handle, a gripping operation is performed in which the tape gripping device grips the tape. When the clincher arm further rotates in the closing direction from the predetermined position with respect to the main handle to be in a closed state, a binding operation is performed to bind objects. The gripping operation and the binding operation are performed alternately. The movement restricting unit is provided to restrict the rotation of the clincher arm in the closing direction from the predetermined position at the time of the gripping operation.

A cable tie mounting tool comprises an upstream jaw and a downstream jaw having concave guidance path portions for the strap of a cable tie, a placing mechanism configured to place a cable tie portion along the common concave guidance path by pushing it strap-end-first along the common concave guidance path starting at the upstream end of the upstream jaw and pushing it in downstream direction, an insertion mechanism for feeding the cable tie strap end of the placed cable tie through the head of the placed cable tie, and a tightening mechanism for tightening the cable tie and possibly cutting it. Also provided is a length adjustment mechanism for adjusting the length of the common concave guidance path.

A strapping tool includes a main body, a strap winding device, and a strap cutting device. The main body is pivotally provided with a first engaging member. The strap winding device includes a spindle. The spindle is provided with a handle, a ratchet gear and a stopper. The handle is pivotally connected with a second engaging member and a push member. When the strapping tool is in a return state, the push member pushes the first engaging member so that the first engaging member disengages from the ratchet gear and the second engaging block leans against the stopper for the user to rotate the spindle freely so as to insert or remove a packing strap.

A binding machine for gardening includes a main handle to draw out a tape, a clincher arm rotatably attached to the main handle, and a tape gripping device attached to the clincher arm. When the clincher arm rotates in a closing direction to a predetermined position with respect to the main handle, a gripping operation is performed in which the tape gripping device grips the tape. When the clincher arm further rotates in the closing direction from the predetermined position with respect to the main handle to be in a closed state, a binding operation is performed to bind objects. The gripping operation and the binding operation are performed alternately. The movement restricting unit is provided to restrict the rotation of the clincher arm in the closing direction from the predetermined position at the time of the gripping operation.

There is provided a binder configured to bind a bound member by being struck out from a binding machine. The binder includes a substantially U-shaped base member that is plastically deformable, and a surface member that is provided on a surface of the base member. There is also provided a coupled binder including plural binders. Each of the binders is coupled to other of the binders on front and back surfaces thereof. The front and back surfaces of each of the binders are not provided with the surface member.

A receptacle for a consumable material, such as a wire spool 2, to be loaded into a machine, such as a wire tying machine 18, comprises first and second indicating means 6, 12 for identifying the receptacle, wherein one of the indicating means 6 is separable from the receptacle.
