Example Embodiment

[0029] Example 1

[0030] Such as Figure 1-5 As shown, a tree saw, including:

[0031] The body 1, the body 1 is disposed on the body 1, and the drive mechanism 11 is connected to the saw chain mechanism 2 and the circuit is driven when the circuit saw is in a pathway state, and the body 1 and the rotary button 6 Connection; as a specific embodiment, the drive mechanism 11 of the present embodiment includes a motor, which can be powered by a DC power source or AC power supply. The saw chain mechanism 2 includes a support plate 3 and a saw chain 4, a groove opened on the support plate 3. The saw chain 4 is provided, the saw chain 4 is engaged with the gear 10, and the motor is connected to the gear 10 by the existing transmission gear 10, and the saw chain 4 is pulled by the saw chain 4, and the saw chain mechanism 2 can also use other conventional structures. Ensure that the cutting function can be achieved;

[0032] The handle 5, the handle 5 is connected to the body 1, and the h...

Example Embodiment

[0039] Example 2

[0040] The difference from the first embodiment is that the tree saw of the present embodiment does not need to perform a mechanical structure, no need to provide the trigger locking portion 12, and simply set the open circuit switching switch on the body 1 or the handle 5. 15, the handle 5 is provided on the handle 5, which is a circuit of the trigger, and the trigger 7 is provided on the trigger 7, and the handle switch 14 and the open switch 15 are connected to the switch circuit, respectively, through the handle switch 14 and the open switch 15. The control switching circuit is turned on, and the shut-off switch 15 is turned off when the switch circuit is turned on, the body 1 or the handle 5 is turned off, and the switch circuit is turned off, so that the switch circuit is in a discontinuation, the drive mechanism 11 cannot start, the saw chain Institution 2 can not run, such as Figure 6 with Figure 7 A shows that the motor is powered by an AC power supply. W...

[0042] Example 3

[0043] The difference between the present embodiment and the second embodiment is that the motor of the present embodiment is powered by a DC power supply, and the open circuit switch 15 is provided on the body 1 or the handle 5, and the switch circuit is provided on the handle 5, the switch circuit is a tree. The saw circuit, the trigger 7 sets the interrupted handle switch 14, the handle switch 14 and the circuit switch 15 respectively connected to the switch circuit, and the switching circuit is controlled by the handle switch 14 and the switching circuit of the switch circuit. The start and stop of the saw chain mechanism, the control panel is also set up on the switch circuit, and the role of the control board is to achieve overcurrent, overprofake protection, such as Figure 7 B shows that the body 1 or handle 5 of the tree saw is rotated to adjust the circuit switch 15, so that the switch circuit is in a discontinuation, the drive mechanism 11 cannot be ac...

Abstract

The invention discloses a tree saw. The tree saw comprises a machine body and a handle, a saw chain mechanism and a driving mechanism are arranged on the machine body, the driving mechanism is connected with the saw chain mechanism and drives the saw chain mechanism when a circuit of the tree saw is in a closed state, and the machine body is connected with a rotary button; the handle is connected with the machine body and provided with a trigger and a reverse self-locking button; and the machine body and at least one of the trigger and the reverse self-locking button form interlocking or cooperatively control the circuit of the tree saw to be in a closed state, and it is ensured that the saw chain mechanism cannot be started when the machine body and/or the handle are/is in a rotating adjusting state. According to the tree saw, the cutting surface of the saw chain mechanism and the handle form a certain angle to complete cutting, so that an area where branches fall off after cutting can be completely avoided, the branches on the reverse side of a tree trunk can be safely and conveniently cut, the problem that an operator of a conventional chain saw is not easy to get close to a cut object to perform reverse side operation is solved, when the tree roots are cut, the hand can be far away from the ground, scratching is avoided, the cutting face is more close to the ground, cut stumps can be flush, and operation is more flexible and safer.

Description

technical field [0001] The invention belongs to the technical field of tree saws, and in particular relates to a tree saw. Background technique [0002] Most of the handles of existing tree saws are fixed, and the angle of the handle cannot be adjusted. The position of the operator is relatively fixed during cutting, which is not conducive to operating on the cutting ground or in a narrow space, and is also not conducive to finding a safer position for cutting. Contents of the invention [0003] In order to solve the problems in the prior art, the object of the present invention is to provide a tree saw. [0004] In order to achieve the above object and achieve the above technical effect, the technical solution adopted in the present invention is: [0005] A tree saw comprising: [0006] Body, the body is provided with a saw chain mechanism and a drive mechanism, the drive mechanism is connected with the saw chain mechanism and drives the saw chain mechanism to perform c...
