Description

The auxiliary power structure that a kind of instrument is used

Technical field

The utility model relates to field of tool, refers in particular to a kind of can being combined with the instrument with stock, so that the auxiliary power structure of user's application of force.

Background technology

General long rod tool, the besom used as cleaning, mop, dustpan etc., great majority are to be hold by one hand to carry out cleaning, user holds after tool bar portion with wrist jail, must repetitiousness bending wrist could be to the tool bar portion application of force, and keeps for a long time pressing from both sides an angle of bend between wrist and arm, and this kind of holding mode can cause canalis carpi to be subjected to oppression, while carrying out cleaning operation with one-handed performance long rod tool for a long time, more easily cause the occupational disease of complication of wrist.In addition, its force mechanism belongs to the third lever, and the drag distance that is lever is greater than application of force distance, so quite require great effort when operation, easily causing heavy to wrist is strength burden.When general work, wrist is exerted oneself, and to be about long rod tool own wt be three to four-fold, for example, and if while holding long rod tool high, when cleaning ceiling and being dust or cobweb, the wrist more long rod tool own wt of exerting oneself is five to six times.Therefore, work with this understanding and easily cause wrist fatigue, cause operating efficiency low.

Summary of the invention

The purpose of this utility model is to overcome weak point of the prior art and the auxiliary power structure that provides a kind of instrument to use, force mechanism when this auxiliary power structure capable of regulating user wrist grips long rod tool, avoid wrist flex, the fatigue strength while reducing operation, and then promote operating efficiency.

For achieving the above object, the utility model adopts following technical scheme:

The auxiliary power structure that a kind of instrument is used, it comprises a body, this body has one first end face and one second end face with respect to the first end face, described body bottom is provided with an arm folder, this arm folder forms one in order to the accommodating perforate of user's forearm, the two side ends span of body is established a handle, this handle takes shape in the first end face, on the second end face, be at least provided with a holder, this holder is by the holding part of an accommodating tool bar portion and be located at one on this holding part and form in order to the fixed part of controlling holding part and clamping or loosen tool bar portion.

The beneficial effects of the utility model are: user can stretch forearm in this arm folder of people via this perforate, this tool bar portion is placed in this holding part, adjust by this force mechanism of user to long rod tool, utilize forearm and elbow to coordinate the application of force to replace traditional with the wrist application of force, use the burden that alleviates user's wrist, extend the duration of work and promote the efficiency of work.

The specific embodiment

Below in conjunction with Figure of description, the utility model is described in further detail:

Specific embodiment 1:

The auxiliary power structure that the utility model is used about a kind of instrument, it is incorporated into user's forearm 11, and can with a tool bar portion 12 combinations, it comprises: a body 20, an arm folder 25, be formed in handle 28 and at least one holder 30 on body 20, wherein:

Body 20 has a 201Ji Yi top, bottom 202, between bottom 201 and top 202, there are two sides 203, form symmetrical structure, body 20 has one first end face 21 and one second end face 22 with respect to the first end face 21, this body 20 is in to having an opening 24 in handle 28 places, the direction between top 202 and bottom 201 for directly to.

Arm folder 25 takes shape in this top 202, and be positioned on this first end face 21, this arm folder 25 is in convex structure, and have always to perforate 26, and the side in this arm folder 25 is provided with an opening port 27, and user's forearm 11 is located in this perforate 26, the moment that tool bar portion 12 is produced, share in whole forearm 11, and utilize forearm 11 and the application of force of elbow to replace the wrist application of force.

Handle 28 takes shape in the first end face 21 of body 10, and is laterally located on opening 24, and user can be gripped on this handle 28 by palm.

At least one holder 30 is located on the second end face 22.In this embodiment, the quantity of holder 30 is two, and lay respectively at

bottom

201 and 202 places, top of this body 20, this holder 30 comprises a holding part 31 and is located at the fixed part 32 on this holding part 31, this tool bar portion 12 is straightly placed in holding part 31, fixed part 32 is in order to control holding part 31 and clamp or to loosen tool bar portion 12, in this embodiment, this fixed part 32 is for being located at a rotary chuck of holding part 31 one end. and fixed part 32 is with rotation mode, controls holding part 31 and clamps or loosen this tool bar portion 12.

As shown in Figure 2, user is in the time using the utility model, first tool bar portion 12 is straightly placed in holding part 31, and with fixed part 32 auxiliary clamps, after forearm 11 is placed in via perforate 26 in arm folder 25, and palm is gripped on handle 28 with fist shape, and fist just can be arranged in the opening 24 of body 20, and do not affect user's operation, and horizontal handle 28 can make wrist and forearm 11 keep the smooth-going state of nature while gripping, avoids bending and compressing canalis carpi.By this, user drives tool bar portion 12 with forearm 11 via the utility model, makes wrist not need repetitiousness bending, and the fatigue strength while reducing operation also promotes operating efficiency.
