no. 1 approach

[0086] (1) The overall composition of the brush cutter

[0087] like figure 1 As shown, the brush cutter 1 is provided with a pipe 2 , a rear end unit 3 , a front end unit 4 , and a handle 6 configured as a long cylindrical shape as a whole. The front unit 4 is provided at one of both ends in the longitudinal direction of the pipe 2 , and the rear unit 3 is provided at the other of both ends in the longitudinal direction of the pipe 2 .

[0088] The pipe fitting 2 includes a first pipe material 14 , a second pipe material 15 , and a bent connection portion 16 that connects these respective pipe materials 14 and 15 . The first pipe material 14 is connected to one end side of the bent connecting portion 16 , and the second pipe material 15 is connected to the other end side of the bent connecting portion 16 .

[0089] The bent connecting portion 16 is a cylindrical member as a whole, and is configured to be bendable at a substantially middle portion thereof. Therefore, the pi...

no. 2 approach

[0177] for Figure 8 The brush cutter 90 of the second embodiment shown has basically the same configuration as that of the brush cutter 1 of the first embodiment except for a part of the configuration including the wiring cutting unit. Therefore, the same reference numerals as those in the first embodiment are attached to the configurations in common with the first embodiment, and description thereof will be omitted, and the differences from the first embodiment will be mainly described.

[0178] In the first embodiment described above, the wiring cutting unit 30 is configured to conduct and cut off the trigger signal line 37 according to the state of the tube 2 . In contrast, in the second embodiment, the wiring cutting unit 92 is configured to conduct and cut off the three power lines 81 , 82 , and 83 according to the state of the pipe 2 .

[0179] like Figure 8 As shown, in the brush cutter 90 , both ends of the trigger switch 70 are connected to the motor control unit ...

no. 3 approach

[0188] In the above-mentioned second embodiment, the electric wires to be cut in the bent state are the three power lines 81 , 82 , and 83 among the eight electric wires laid between the cells. In contrast, in the third embodiment, an example is shown in which the sensor power line 84 and the sensor ground line 85 are cut off instead of the three power lines 81 , 82 , and 83 . It is the same as the second embodiment except that the electrical wiring to be cut is different.

[0189] like Figure 10 As shown, the brush cutter 100 of the third embodiment is provided with a wiring cutting portion 102 at the bending connection portion 101 of the pipe 2 . The wiring cutting unit 102 has a pair of connectors 103 and 104 . The first connector 103 is disposed on the first holding portion 31 of the bent connecting portion 101 , and the second connector 104 is disposed on the second holding portion 32 of the bent connecting portion 101 . The pair of connectors 103 and 104 are provided...

Abstract

In a working machine with an operation rod, reduction of transmission and storage performance can be restrained and the length is allowed to be smaller than that in the general use state. The working machine (1) according to one aspect of the present disclosure comprises an operation rod (2), a leading end unit (4), a rear end unit (3), and a drive permitter. The operation rod is configured to be transformable between an extended state and a non-extended state. The leading end unit is provided at one end of the operation rod. The leading end unit comprises a motor configured to drive a working element. The rear end unit is provided at the other end of the operation rod. The rear end unit comprises a controller configured to control driving of the motor. The drive permitter is configured to permit driving of the motor when the operation rod is in the extended state and not to permit driving of the motor when the operation rod is in the non-extended state.

Description

technical field [0001] The present invention relates to a work machine with an operating lever. Background technique [0002] As a working machine having an operating lever, for example, a brush cutter configured to provide a disc-shaped gravity blade on the front end side of the operating lever, and to perform cutting operations such as grass and trees by rotating the gravity blade with a motor is known. . [0003] As a technique for improving the transportability and storage capability of such a brush cutter, Patent Document 1 proposes a technique for configuring an operation lever in a divisible manner. [0004] Patent Document 1: Japanese Patent Laid-Open No. 2011-254760 [0005] However, splitting the lever means that the brush cutter is physically split into two. Therefore, for example, it is necessary to hold two objects during transportation, which does not necessarily improve the transportation performance. In addition, the burden on management to properly manag...
