Abstract
The utility model discloses a pneumatic tool sleeved with a protecting structure. The pneumatic tool comprises a gun-shaped main body, a chuck, a grab handle, and a switch, wherein the chuck is arranged at the front end place of the main body in a shaft manner to rotate; the grab handle stretches downward from the rear end of the main body and can be held by a human hand; the switch is arranged at the front edge part of the grab handle and can starts the chuck to run; a detachable protecting external member is sleeved upon the main body; a mounting hole for sleeving upon the main body is formed in the protecting external member concavely; a sleeving inlet communicated with the mounting hole is formed in the lower edge part of the protecting external member; an outer cover part is arranged at the front end part of the protecting external member to cover the chuck; wing parts are convexly arranged on the two sides of the protecting external member to allow human fingers to contact and prop. As the protecting external member is sleeved upon the main body and comprises the outer cover part to cover the chuck and two wings parts to allow a thumb and an index finger of a human body to contact and prop, when operating, the fingers of the human body do not touch the rotating chuck to operate safely in use.
Description
Technical field
The utility model relates to field of tool, refers to especially a kind of pneumatic tool that is arranged with protection structure that reaches safe handling effect.
Background technology
General power tool is when turning operation to article, reaction force can pass through body top via chuck, only having lever lower portion to be subject to the gripping of user's hand is supported, body top lacks the strength effectively supporting, when this will cause this power tool of operation, easily produce and rock, allow instrument correctly aim at article and turn.
Although another kind of power tool allows body top can obtain the strength of effective support, yet user's forefinger is because the relation of stretching out forward.If user's forefinger is longer, often can stretch and touch chuck, when chuck is running up under state, tend to user's hand to damage.
Summary of the invention
The purpose of this utility model be to overcome weak point of the prior art and provide a kind of be arranged with protection structure pneumatic tool.
For achieving the above object, the utility model adopts following technical scheme:
A kind of pneumatic tool that is arranged with protection structure, it comprises that one is the body of rifle shape, one axle is located at can the rotate chuck of shape of body front end place, one lever that can be gripped for human hands to downward-extension by body rear end, and one be arranged on the switch that lever leading edge place can start chuck running, a sheathed detachable protective external member on described body, the inside of protection suite is concaved with an installation hole for body fit, this protection suite lower edge offers a cover entrance being connected with installation hole, protection suite front end place is provided with one can make to chuck the sheath portion of coated, protection suite dual-side place respectively convexes with one and supplies human finger to abut against the alar part of contact.
This novel beneficial effect is: utilize a sheathed protection suite on body, this protection suite has can form to this chuck the sheath portion of coated, and supplies human hands thumb and forefinger to abut against the both wing portions of contact.During operation, can allow human finger avoid false touch to the chuck in rotating, reach whereby the result of use of safety operation.
Accompanying drawing explanation
Fig. 1 is STRUCTURE DECOMPOSITION figure of the present utility model.
Fig. 2 is cutaway view of the present utility model.
The specific embodiment
Below in conjunction with Figure of description, the utility model is described in further detail:
As shown in Figure 1, 2; the utility model is about a kind of pneumatic tool that is arranged with protection structure; it includes a power tool 30 and a protection suite 40, and this power tool 30 comprises that body 31, an axle that is rifle shape is located at can rotate chuck 32, the lever 33 and that can be gripped for human hands to downward-extension by these body 31 rear ends of shape of body 31 front end places and is arranged on the switch 34 that these lever 33 leading edge places can start these chuck 32 runnings.These lever 33 lower ends are provided with a joint 331 passing into for pressure-air.
When entering this lever 33, pressure-air works as user to this switch, after can being subject to this switch 34 and stopping that presenting closed condition 34 presses, pressure-air just can arrive this body 31 tops by this switch 34, and the motor mechanism (not shown) to these body 31 inside turns, this motor mechanism is the common mechanism of common mechanical, this motor mechanism can transmit power and drive this chuck 32 runnings, these chuck 32 centre can be for gripping an instrument (not shown), this instrument can be screwdriver, die nut, the article such as drill bit, so after these chuck 32 runnings, just can be with power driven tools to carry out the various operations that turn.
When user will use this novel; can select to allow that this protection suite 40 is sheathed is fixed on this body 31; so user's hand utilizes thumb and forefinger to clamp to abut against 44 of the alar parts of this protection suite 40; its first web part is held and is against these body 31 end edges and can effectively supports; user's middle finger extends these switch 34 places and controls push action; now the sheath portion 43 of this protection suite 40 can be covered and cover this chuck 32; the forefinger that can avoid human body to stretch out touches the chuck 32 in running, reaches whereby safe operating effect.
In addition; when user does not want to use this protection suite 40; can select to allow protection suite 40 separate out from body 31; so the whole hand of user is to be held on this lever 33; user's forefinger extends switch 34 places and controls push action; therefore all fingers of user can not contact with the chuck 32 in running, in operation, can reach safe result of use equally.
The utility model is mainly the means of using a power tool 30 and a protection suite 40 to cooperatively interact, user can select to allow protection suite 40 be installed on power tool 30, protection suite 40 front ends are extended with one can cover to chuck 32 sheath portion 43 of coated, limit, the left and right sides is respectively equipped with one and holds the tactile alar part of butt 44 for user's thumb and forefinger, when user stretches out thumb and forefinger, protection suite 40 is done to clamp while gripping, this sheath portion 43 can avoid the finger that human body stretches out mutually to touch with the chuck 32 in running, reach whereby the protection effect of safe handling.In addition; this novel protection suite 40 also can be selected separated with power tool 30; allow user's hand be held in the enterprising line operate of lever 33 of power tool 30; so basis is novel can be according to user's operating habit; use or do not use this protection suite 40, conversion hand operates power tool 30 with different holding modes, and under different operating state; user's hand can not contact with the chuck 32 in running, has quite safe result of use.
The above is only to preferred embodiment of the present utility model; not scope of the present utility model is limited; therefore do not departing under the prerequisite of the utility model design spirit; equivalence that the common engineers and technicians in this area do structure described in the utility model, feature and principle changes or decorates, and all should fall in the protection domain that the utility model applies for a patent.
