Abstract
Description
Technical Field
[0001] The present application relates to the technical field of electric tools, and in particular to a novel locking structure. Background Art
[0002] Specifically, the common locking methods in the prior art have the following problems: First, the position of the right-angle pad for locking is easy to scratch the contact surface during operation, which not only affects the appearance of the tool, but also may cause premature damage to the pad due to long-term friction. Secondly, some locking structures lack effective pad design, resulting in angle deviation during the locking process, causing deviation in the cutting angle.
[0003] In order to solve the above problems, the market is in urgent need of a new locking structure that can not only ensure that no angle deviation occurs during locking, but also effectively protect the contact surface from damage and improve the durability of the gasket.
[0004] The above contents are only used to assist in understanding the technical solution of the present application, and do not constitute an admission that the above contents are the closest prior art to the present application. Summary of the invention
[0005] Based on this, the present application provides a new locking structure to solve one of the above technical problems.
[0006] The technical solution adopted by the present application to solve its technical problems is to include: a base; an adjusting disk rotatably arranged on the base; a locking structure, including a locking rod, a limiting plate, and a gasket, one end of the locking rod abuts against one side of the gasket through the limiting plate, both ends of the gasket in the length direction are clamped on the limiting plate, a spring is sleeved on the locking rod, one end of the spring abuts against one end of the limiting plate, and the locking rod is formed with a convex plate at the other end of the spring to abut against the spring, and the limiting plate is installed on the adjusting disk; when the locking rod applies force in the direction of the gasket, the gasket bends and abuts against the base to achieve a locking effect, and when the locking rod no longer applies force, the spring causes the gasket to automatically rebound, the gasket is no longer in contact with the base, and the locking structure is unlocked.
[0007] In some embodiments, the locking structure also includes a locking trigger and a locking nut. The locking trigger is rotatably set on the adjusting disk, the end of the locking rod away from the gasket is threadedly connected to the locking nut, and the locking trigger abuts against the other end of the locking nut. The locking trigger is roughly L-shaped.
[0008] In some embodiments, a backing plate is formed at one end of the locking nut that contacts the locking trigger.
[0009] In some embodiments, the limiting plate is provided with a groove for the gasket to be engaged.
[0010] In some embodiments, both ends of the gasket are bent and the main body is in an arc shape.
[0011] In some embodiments, the gasket is made of an elastically deformable material, for example, the gasket is an elastic metal sheet.
[0012] In some embodiments, the limiting plate is connected to the adjusting disk by screws.
[0013] In some embodiments, a limiting block for accommodating the locking rod is formed on the adjusting disk.
[0014] The beneficial effect of the present application is that when the locking rod applies force, the gasket bends and makes surface-to-surface contact with the base, increasing the contact surface and making the entire locking structure more stable, accurate and easy to maintain. This structure not only simplifies the assembly and maintenance process, but also significantly improves the tool's service life and user convenience by reducing wear points and adding an automatic rebound mechanism.

[0020] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to achieve. When the combination of technical solutions is contradictory or cannot be achieved, it should be considered that the combination of such technical solutions does not exist and is not within the scope of protection of this application.
[0021] In the embodiments of this application, please refer to Figure 1-3 As shown, the present application provides a new locking structure, which mainly includes: a base 1; an adjusting disk 2, which is rotatably arranged on the base 1; a locking structure 3, including a locking rod 33, a limiting plate 34, and a gasket 35, one end of the locking rod 33 abuts against one side of the gasket 35 through the limiting plate 34, and both ends of the gasket 35 in the length direction are clamped on the limiting plate 34, a spring 36 is sleeved on the locking rod 33, one end of the spring 36 abuts against one end of the limiting plate 34, and the locking rod 33 is formed with a convex plate at the other end of the spring 36 to abut against the spring 36, and the limiting plate 34 is installed on the adjusting disk 2; when the locking rod 33 applies force in the direction of the gasket 35, the gasket 35 bends and abuts against the base 1 to achieve a locking effect, and when the locking rod 33 no longer applies force, the spring 36 causes the gasket 35 to automatically rebound, the gasket 35 is no longer in contact with the base 1, and the locking structure 3 is unlocked.
[0022] Specifically, the locking rod 33 applies force downward, causing the gasket 35 to deform and squeeze the base 1 while squeezing the spring 36 to achieve a locking effect. When the locking rod 33 no longer applies force, it automatically resets under the rebound force of the spring 36 to achieve the quick lock function.
[0023] Some preferred / improved embodiments based on the above embodiments will be described below. Any one of the following embodiments may be selected, or multiple embodiments may be selected and combined.
[0024] Reference Figure 1 As shown, the locking structure also includes a locking trigger and a locking nut. The locking trigger 31 is rotatably set on the adjusting disk 2. The end of the locking rod 33 away from the gasket 35 is threadedly connected to the locking nut 32. The locking trigger 31 abuts against the other end of the locking nut 32. The locking trigger 31 is roughly L-shaped. With this arrangement, the force applied to the locking trigger 31 can be converted into a force to lock the locking structure 3.
[0025] Reference Figure 3 As shown, in order to prevent the surface of the locking trigger 31 from being damaged when the locking trigger 31 and the locking nut 32 cooperate, a pad 321 is formed at one end of the locking nut 32 that contacts the locking trigger 31 .
[0026] Specifically, the limiting plate 34 is provided with a groove for the gasket 35 to be engaged. This arrangement allows the gasket 35 to be fixed in the groove and is easy to install.
[0027] More specifically, in order to allow the gasket 35 to be snapped into the limiting plate 34 and then fixed on the limiting plate 34 , both ends of the gasket 35 are bent and the main body is in an arc shape.
[0028] Preferably, the gasket 35 is made of elastically deformable material, for example, the gasket 35 is an elastic metal sheet. In this way, when the limit rod of the gasket 35 is pressed down, the gasket 35 is bent by pressure and abuts against the base.
[0029] Reference Figure 2 As shown, the limiting piece 34 is connected to the adjusting disk 2 by screws. Such an arrangement enables the limiting piece 34 to be fixed on the adjusting disk 2 more stably.
[0030] Preferably, in order to limit the position of the locking rod 33 during installation and make installation more convenient, a limiting block 21 for accommodating the locking rod 33 is formed on the adjusting disk 2 .

In order to avoid obscuring the concept of the present application, some details known in the art are not described. Based on the above description, those skilled in the art can fully understand how to implement the technical solution disclosed herein.
[0032] Finally, it should be noted that the above is only a preferred embodiment of the present application, and the aforementioned embodiments are only used to illustrate the technical solution of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that it is still possible to modify the technical solutions recorded in the aforementioned embodiments, or to make equivalent replacements for some of the technical features therein.
