[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-6 As shown, a cable mounting structure for a power tool includes a workbench 1 and a sawing mechanism 3 mounted on the workbench 1. The sawing mechanism 3 includes a head 21 and a guide rail assembly 2 and a cutting mechanism that are slidably mounted on the head 21. The guide rail assembly 2 includes a guide rod 22 that is slidably fitted inside the head 21. A limiting block 23 is provided at the rear end of the guide rod 22. A mounting seat 231 is provided on the limiting block 23. The mounting seat 231 has a mounting hole 230 through which the cable 5 of the sawing mechanism 3 passes. A flange 51 is provided on the outer periphery of the cable 5. A spring 6 is also sleeved on the outer periphery of the cable 5. The spring 6 abuts against the flange 51 and the mounting seat 231. The spring 6 always has a tendency to push the cable 5 backward through the flange 51. The inner diameter of the spring 6 is larger than the diameter of the mounting hole 230.

[0024] The sawing mechanism 3 is pivotally connected to the guide rail assembly 2 via a pivot shaft 25. One end of the cable 5 is electrically connected to the sawing mechanism 3, and the other end of the cable 5 is connected to a plug 52.

[0025] The front end of the spring 6 abuts against the rear end face of the mounting base 231, and the rear end of the spring 6 abuts against the front end face of the flange 51. The flange 51 is configured as a sleeve fixedly fitted around the outer periphery of the cable 5. The flange 51 is located at the end of the cable 5 near the plug 52 to ensure that the cable 5 is not excessively pulled when the cutting mechanism is in operation.

[0026] The mounting seat 231 is provided with an opening 2301 for the cable 5 to enter the mounting hole 230, the opening 2301 is communicated with the mounting hole 230, and the edge of the opening 2301 of the mounting seat 231 is provided with a guide portion 2311, which is a rounded corner, and the guide portion 2311 is used for guiding when the cable 5 is installed.

[0027] In addition, the distance between the openings 2301 is smaller than the diameter of the cable 5, and since the outer part of the cable 5 is rubber, which is elastic, the cable 5 can be installed into the mounting hole 230 through the opening 2301 during installation, and the opening 2301 is smaller than the diameter of the cable 5, which can prevent the cable 5 from being separated from the mounting hole 230.

[0028] The saw mechanism 3 has an initial state and a cutting state, when the saw mechanism 3 is in the initial state, the part of the cable 5 between the mounting seat 231 connection and the saw mechanism 3 is in a straight state pulled by the spring 6, when the saw mechanism 3 switches to the cutting state, the saw mechanism 3 needs to be pressed down, at this time the cable 5 will follow the saw mechanism 3 to move to the movement direction of the saw mechanism 3, and when the saw mechanism 3 switches back to the initial state, the flange 51 can be pushed back by the spring 6, and the cable 5 can also be reset synchronously, so that the cable 5 is reset synchronously when the saw mechanism 3 is reset, at this time the part of the cable 5 between the mounting seat 231 and the saw mechanism 3 is still in the initial state after reset, so the cable 5 will not be clamped.

[0029] Further, in the present application, the limiting block 23 is located at the end of the guide rod 22 away from the saw mechanism 3, and the limiting block 23 is limited to cooperate with the machine head 21, so as to limit the maximum movement distance of the guide rod 22, and in the present application, the guide rod 22 is two, and the two guide rods 22 are slidingly fitted in the machine head 21, and the stability during sliding can be increased by the two guide rods 22.

[0031] The buckle 35 limits the cable 5, prevents the cable 5 near the driving member 31 from being clamped, and the installation of the buckle 35 and the buckle 35 further prevents the cable 5 from being clamped.

[0032] The pivot shaft 25 is provided with a torsion spring 7, one end of the torsion spring 7 abuts against the connecting member 34, the other end of the torsion spring 7 abuts against the connecting frame 24, and the torsion spring 7 always has a tendency to push the connecting member 34 away from the connecting frame 24.

[0033] The machine head 21 is provided with a fastening assembly 4 for locking the guide rod 22, the fastening assembly 4 comprises a knob 41 and a fastening bolt 42, the knob 41 is fixedly installed on the fastening bolt 42, the fastening bolt 42 is threadedly connected with the machine head 21, and the fastening bolt 42 reciprocally moves along the axial direction between a first position and a second position;
