Description

Technical Field

[0001] The utility model relates to the field of hardware equipment, in particular to an electric saw sharpener. Background Art

[0002] A chain saw, also known as an oil saw or an electric saw, is a hand-held saw powered by a gasoline engine or electricity. It is mainly used for logging and lumbering. Its working principle is that the staggered L-shaped blades on the saw chain move horizontally to perform a shearing action. Chain saws are generally divided into motorized chain saws, non-motorized chain saws, etc. After long-term use, a chain sharpener is required to grind the chain.

[0003] In order to facilitate the grinding of the chain, relevant patents include 2023214594067, a chain sharpener, and 2023202469263, a chain saw grinding device with adjustable grinding angle.

[0004] The above patents specifically disclose two solutions:

[0005] 1. Grinding with an electric grinder, and the grinding angle can be adjusted through the equipped caliper;

[0006] 2. Fixing a manual grinding shaft on the chain saw at a certain angle and grinding manually.

[0007] Each of these two solutions has its drawbacks. The first electric grinding is relatively labor-saving, but the adjustable angle cannot be fixed, so there is still inconvenience. The second has an adjustable and fixable angle, but the grinding is manual, so it still needs to be improved. Utility Model Content

[0008] To solve the above problems, the utility model provides an electric saw sharpener, and the specific technical solution is as follows:

[0009] An electric saw sharpener includes an electric grinder and a regulator. The regulator includes a reference frame. A connecting frame is pivotally connected to the reference frame. The connecting frame can rotate on the reference frame. An indicating part is provided at the end of the connecting frame. Angle scale lines are provided on the reference frame. A limiting structure is provided on the reference frame. The limiting structure cooperates with the connecting frame to limit the rotation of the connecting frame. The electric grinder is fixed on the connecting frame of the regulator.

[0010] Furthermore, pivot shafts are provided at both ends of the connecting frame. An annular connecting part is provided between the pivot shafts at both ends. Internal threads are provided in the inner hole of the connecting part. External threads are provided at the end of the electric grinder for matching.

[0011] Furthermore, a metal insert is provided in the connecting part, and the internal threads are formed in the metal insert.

The pivot shaft at one end of the connecting frame passes through the lower housing and an end cap is installed at the end of the pivot shaft. The indicating portion is provided on the end cap. The angular scale lines on the reference frame are provided on the side surface of the lower housing and surround the end cap.

[0014] Furthermore, the limiting structure includes a thimble installed on the lower housing. The position of the thimble corresponds to the pivot shaft at one end of the connecting frame. The thimble is screwed on the lower housing and can move axially along the screw thread to press tightly against the corresponding pivot shaft.

Detailed implementation manners

[0027] The present utility model will be further described below in conjunction with the accompanying drawings.

[0028] Refer to Figure 1-6 A saw sharpener provided by the present utility model shown in the figure includes an electric grinder 1 and a regulator 2. The regulator 2 includes a reference frame 201. A connecting frame 202 is pivotally connected to the reference frame 201. The connecting frame 202 can rotate on the reference frame 201. An indicating portion 3 is provided at the end of the connecting frame 202. An angle scale line 4 is provided on the reference frame 201. A limiting structure is provided on the reference frame 201. The limiting structure cooperates with the connecting frame 202 to limit the rotation of the connecting frame 202. The electric grinder 1 is fixed on the connecting frame 202 of the regulator 2.

[0029] The principle of the present utility model is to first fix the electric grinder 1 on the connecting frame 202 of the regulator 2, and then determine the angle by using the indicating portion 3 on the connecting frame 202 and the angle scale line 4 on the reference frame 201, and then fix the angle of the connecting frame 202 through the limiting structure; during grinding, the reference frame 201 is attached to the guide plate 5 of the chainsaw (refer to Figure 2 ), and the chain is ground by the electric grinder 1.

[0030] As a preferred implementation manner, pivot shafts 202a are provided at both ends of the connecting frame 202. An annular connecting portion 202b is provided between the pivot shafts 202a at both ends. Internal threads are provided in the inner hole of the connecting portion 202b. External threads can be provided at the end position of the electric grinder 1. The electric grinder 1 is fixed to the connecting frame 202 in a screwed manner. In addition to this implementation manner, the electric grinder 1 can also be fixed by means of clamping, plugging, etc.

[0031] More specifically, the entire connecting frame 202 can be integrally formed by injection molding with plastic, and a metal insert 6 is provided in the middle connecting portion 202b. Threads are machined on the inner wall of the metal insert 6 to improve the service life.

[0032] As a preferred embodiment, the reference frame 201 includes an upper housing 201a and a lower housing 201b. The upper housing 201a and the lower housing 201b are fixedly connected by screws. The pivot shafts 202a at both ends of the connecting frame 202 are installed between the upper housing 201a and the lower housing 201b. A through hole is provided in the middle of the upper housing 201a and the lower housing 201b to accommodate the connecting frame 202 and allow it to have a space for rotation. At the same time, a reference plane is provided on the lower surface of the lower housing 201b, and this reference plane is used to determine the angle of the connecting frame 202. The pivot shaft 202a at one end of the connecting frame 202 passes through the lower housing 201b, and an end cap 7 is installed at the end of the pivot shaft 202a. The indicating portion 3 is provided on the end cap 7. As an alternative embodiment, the indicating portion 3 can be a triangle, an arrow, or other indentations, protrusions, or labels with an indicating function. The angle scale line 4 on the reference frame 201 is provided on the side surface of the lower housing 201b and is arranged around the end cap 7.

[0033] As a preferred embodiment, the limiting structure includes a thimble 8 installed on the lower housing 201b, and the position of the thimble 8 corresponds to the pivot shaft 202a at one end of the connecting frame 202. The thimble 8 is screwed on the lower housing 201b, and the thimble 8 can move axially along the screw thread and abut against the corresponding pivot shaft 202a, thereby restricting the rotation of the connecting frame 202 and fixing the angle of the connecting frame 202.

[0034] On this basis, as a preferred embodiment, a rubber sleeve 9 is sleeved on the pivot shaft 202a corresponding to the thimble 8. The function of the rubber sleeve 9 is that when the thimble 8 abuts against the pivot shaft 202a, the deformation ability of the rubber sleeve 9 can be utilized to make the thimble 8 sink into the rubber sleeve 9, increasing the contact area and also improving the friction force, making the connection of the connecting frame 202 more firm and preventing it from loosening after being fixed.

[0035] More specifically, the upper housing 201a and the lower housing 201b can be integrally formed by injection molding with plastic. A metal nut 10 is installed on the lower housing 201b, and at the same time, a plastic fixing piece 13 is provided to press and fix the metal nut 10 inside the lower housing 201b. The thimble 8 is screwed on the metal nut 10, and the metal nut 10 can improve the service life.

[0036] Preferably, a card slot 11 is provided outside the lower housing 201b, and a hexagonal wrench 12 is clamped in the card slot 11. The hexagonal wrench 12 cooperates with the thimble 8 for operating the thimble 8.

[0037] The technical principle of the present utility model has been described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present utility model and cannot be construed as limiting the protection scope of the present utility model in any way. Based on the explanations herein, those skilled in the art can readily conceive of other specific embodiments of the present utility model without creative efforts, and these embodiments will fall within the protection scope of the claims of the present utility model.
