Description

A kind of assist handle that is used for handheld tool

Technical field:

The utility model relates to and a kind ofly is used for handheld tool, especially for the assist handle of hand held electric tool.

Background technology:

Most of hand held electric tools all comprise the main handle that is used to operate electric tool, but sometimes, the user prefers electric tool and also has assist handle, assist handle provides a kind of alternative control mode to the user, the user is applied more energetically during using electric tool and the user is eased off the pressure etc.At present, some electric tool comprises the assist handle in the instrument of being built in, yet sometimes, because assist handle may become obstacle, therefore, people wish that there is dismountable assist handle the instrument upper erengy band.

The utility model content:

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of dismountable handheld tool assist handle is provided, and it is not only simple in structure, and manufacturing cost is lower, and assembling, convenient disassembly, and the scope of application is wider.

The assist handle that is used for handheld tool that provides according to the utility model, comprise handle and lock ring, described lock ring lower end has an opening and Open Side Down extends one section hollow cylinder by this, described handle upper end is provided with a screw rod, described screw rod is threaded with the internal perisporium of hollow cylinder, and this hollow cylinder stretches in the lock ring certainly, and described inserting end is equipped with latch segment.

In addition, the utility model also has following attached technical characterictic:

Described latch segment is a U-shaped body, and it has the arc-shaped upper ends face.

The diameter of described opening is greater than the internal diameter of described hollow cylinder, and forms a step surface that is used for the described latch segment of backstop thus.

Described handle upper end also is provided with one and is used to accept the cavity of described hollow cylinder bottom.

Described latch segment is fixed on the inserting end of described screw rod by a backing-up screw.

The assist handle that is used for handheld tool according to the utility model provides has following advantage with respect to prior art:

At first, assist handle described in the utility model is being installed on the hand held electric tool or when hand held electric tool is dismantled, is only needing swing handle, and make on it latch segment withstand or unclamp hand held electric tool and get final product, thereby very convenient; Simultaneously, because the stroke of latch segment is adjustable, therefore, assist handle of the present utility model is applicable to the electric tool of various different-diameters, and range of application is wider.

Secondly, assist handle described in the utility model only is made up of handle, screw rod, latch segment and lock ring, thereby structure is quite simple, and manufacturing cost is lower, helps improving competitiveness of product.

Description of drawings:

Introduce the utility model in detail below in conjunction with the drawings and specific embodiments.

Fig. 1 is the structural representation of assist handle releasing orientation described in the utility model, and 5 is handheld tool among the figure;

Fig. 2 is the structural representation of assist handle locking state described in the utility model, and 5 is handheld tool among the figure.

The specific embodiment:

See figures.1.and.2, the assist handle that provides according to the utility model, comprise handle 1 and lock ring 2, described lock ring 2 lower ends have an opening 21 and extend one section hollow cylinder 22 downwards by this opening 21, described handle 1 upper end is provided with a screw rod 3, described screw rod 3 is threaded with the internal perisporium of hollow cylinder 22, and this hollow cylinder 22 stretches in the lock ring 2 certainly, and described inserting end is equipped with latch segment 4.When needs are installed to assist handle when using on the handheld tool, at first lock ring 2 is enclosed within on the handheld tool 5, screw handle 1 then, make the latch segment 4 of its upper end upwards withstand handheld tool and get final product; During dismounting, then only need counter-rotation handle 1, make latch segment 4 unclamp locking downwards, just can take off assist handle handheld tool 5, thus very convenient.

Described latch segment 4 is a U-shaped body, it has arc-shaped upper ends face 41, this structural design can better be locked at assist handle on the handheld tool, improve the fixing of locking, and avoid tool surfaces is crushed, certainly, those skilled in the art also can be provided with soft gasket on arc-shaped upper ends face 41, is not crushed further to guarantee tool surfaces.

The diameter of described opening 21 is greater than the internal diameter of described hollow cylinder 22, and form a step surface 23 that is used for the described latch segment 4 of backstop thus, with prevent dismounting during assist handle because of 1 revolution excessively causes handle 1 disengaging lock ring 2 to handle, thereby avoided the trouble reinstalled.Described handle 1 upper end also is provided with one and is used to accept the cavity 11 of described hollow cylinder 22 bottoms, this cavity 11 can improve the steadiness that handle 1 is connected with lock ring 2, guarantee can be reliable when assist handle is on being installed to handheld tool use, and increase the aesthetic property of appearance.

In addition, handle 1 with the mounting means of lock ring 2 is: the screw rod 3 with handle 1 upper end screws in hollow cylinder 22 earlier, screw rod 3 upper ends is stretched in the lock ring 2, and then latch segment 4 is fixed on the inserting end of screw rod 3 by backing-up screw 6.

The foregoing description is only for the usefulness that the utility model is described; and be not to restriction of the present utility model; the those of ordinary skill in relevant technologies field; under the situation that does not break away from spirit and scope of the present utility model; can also make various variations and modification; therefore all technical schemes that are equal to also belong to category of the present utility model, and scope of patent protection of the present utility model should be limited by each claim.
