Detailed Description

Example one

The multifunctional auxiliary handle of the embodiment is applied to the angle grinder 1, and as shown in fig. 1, a gear disc 2-3 of the multifunctional auxiliary handle additionally extends to one side of a grinding tool head 1-2 of the angle grinder 1 with a main handle 1-1. The center of the gear disc 2-3 is hinged with the auxiliary grab handle 2 through a hinged pin shaft 2-4.

The gear disc 2-3 is provided with an upper disc and a lower disc, and the upper disc is provided with a plurality of gear holes 2.1 which are distributed at intervals in the circumferential direction. The auxiliary grab handle 2 comprises a grab handle body 2-1 and a connecting handle 2-2, the outer end of the connecting handle is hinged with the gear disc through a hinged pin shaft 2-4, and the outer end of the connecting handle extends into a position between an upper disc and a lower disc of the gear disc 2-3.

The connecting handle 2-2 is provided with a spiral groove 2.2, and an unlockable positioning structure inserted into the gear hole 2.1 is shown in figures 2 and 3 and comprises a locking sleeve 2-5 with a shifting handle 2.3 and sleeved on the connecting handle 2-2 and a positioning pin 2-6 arranged in a radial hole of the connecting handle 2-2, wherein the inner end of the positioning pin 2-6 is sleeved with a spring 2.7, so that one end of the positioning pin tends to be inserted into the gear hole 2.1. The inner hole of the locking sleeve 2-5 and the spiral groove 2.2 form a spiral pair, and one end of the locking sleeve 2-5 extends to form a limiting claw 2.4 which can be inserted into a gap between the connecting handle 2-2 and the lower disc. When the shifting handle is shifted to enable the limiting claw of the locking sleeve to exit from the gap between the connecting handle and the lower disk, the positioning pin is pressed downwards to axially displace and be separated from the gear hole by overcoming the acting force of the spring, and then the auxiliary grab handle can be rotated relative to the gear disk to change the angular position (such as the position from a solid line to a dotted line in the figure 1) between the auxiliary grab handle and the angular sand mill; after the angular position is adjusted, the positioning pin is loosened, the positioning pin is automatically inserted into a proper gear hole under the action of the spring, then the shifting handle is shifted to enable the limiting claw of the locking sleeve to be inserted into a gap between the connecting handle and the lower disc, the positioning pin inserted into the gear hole cannot axially move, and the positioning pin can be reliably kept at the adjusted angular position.

Summarizing, the multifunctional auxiliary handle adopting the embodiment has the following characteristics:

1) The multi-angle switching in a plane is realized, the use requirements of different scenes are facilitated, and the method is more in line with ergonomics;

2) The angle can be conveniently and quickly switched by pressing the positioning pin without dismounting;

3) After being adjusted, the positioning pin can be conveniently locked, the displacement of the positioning pin is prevented, and the application reliability is ensured.

Example two

The multifunctional auxiliary handle of the embodiment is also applied to the angle sanding machine 1, and as shown in fig. 4, the basic structure of the multifunctional auxiliary handle is the same as that of the embodiment. The main differences are

The gear disk 2-3 is not formed integrally with the angle sander 1, but is screwed into a threaded bore on the side of the grinding tool head 1-2 of the angle sander 1 by means of its own threaded head 2.5. Therefore, the fixing device can be fixed at the left side, the right side, the top side and the like as required, and can be conveniently detached during package and transportation.

In addition, the unlocking positioning structure is shown in figures 4, 5 and 6 and comprises a fixed gear disc 2-7 which is coaxially hinged with the connecting handle 2-2 and is arranged between the upper disc and the lower disc of the gear disc 2-3 and a positioning pin 2-6 which is arranged in a radial hole of the connecting handle 2-2, wherein the inner end of the positioning pin 2-6 is sleeved with a spring 2.7, so that one end of the positioning pin is inserted into the gear hole 2.1.

The gear fixing disc 2-7 is provided with a group of positioning holes 2.8 corresponding to the positions of the gear holes 2.1 of the gear disc 2-3 respectively, and a shifting finger 2.6 extends out of the outer side of the gear fixing disc, and the shifting finger 2.6 is provided with a bulge which is in elastic contact with a peripheral sawtooth concave of a lower disc of the gear disc 2-3.

When the positioning hole of the fixed gear plate is aligned with the gear hole of the gear plate by the dial finger, the positioning pin is pressed downwards to axially displace and be separated from the gear hole by overcoming the acting force of the spring, and the auxiliary grab handle can be rotated relative to the gear plate to change the angular position of the auxiliary grab handle and the angular sanding machine; after the angular position is adjusted, the positioning pin is loosened, the positioning pin is automatically inserted into a proper gear hole under the action of the spring, then the shifting finger is shifted to enable the positioning hole of the gear fixing plate to be staggered with the gear hole of the gear fixing plate, the protrusion of the shifting finger is just clamped in the sawtooth recess of the lower plate of the gear fixing plate, obvious in-place hand feeling is generated, the positioning pin inserted into the gear hole cannot axially displace, and the positioning pin can be reliably kept at the adjusted angular position.

In addition to the above embodiments, the present invention may have other embodiments. All the technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the protection scope claimed by the present invention.
