Embodiment
Hand-hold power tool 100 as shown in Figure 1 is specially a kind of angle grinder, and it mainly can be used in cutting, grinds
And brushing metal and stone material etc..
As depicted in figs. 1 and 2, hand-hold power tool 100 includes：Housing 10, prime mover, output shaft 20 and shield 30,
Wherein, prime mover is arranged in housing 10.
Housing 10 is also formed with handle portion 11 and receiving portion 12, and handle portion 11 is used to grip for user, and handle portion 11 is basic
Extend along the direction of first straight line 101, prime mover is arranged in the space that handle portion 11 surrounds, and receiving portion 12 is arranged on handle
One end of hand 11, receiving portion 12 substantially extend along perpendicular to the direction of first straight line 101, what receiving portion 12 surrounded
Transmission system can be accommodated in space.
Specifically, handle portion 11 is also symmetrical arranged on a split parallel to first straight line 101, prime mover tool
Body can be motor.The one end of handle portion 11 along first straight line 101 connects receiving portion 12, the other end can be used for being connected as motor
The battery bag of power supply.
As shown in Figures 1 to 4, receiving portion 12 includes upper lid 121 and lower cover 122, and upper lid 121 and lower cover 122 can pass through
Screw 41 is fixedly connected, around the space formed for accommodating transmission system when upper lid 121 and lower cover 122 combine.
Output shaft 20 is used to receive and installation tool annex 42, and for angle grinder, attachment 42 is specifically as follows
Grinding.Output shaft 20 can be rotated by prime mover driven with first axle 102 for axle, and output shaft 20 can drive attachment when rotating
42 rotate in the lump, so as to realize the function of cutting, grinding etc..
The technical solution of the utility model for convenience of explanation, as shown in Fig. 2 definition is along parallel to the side of first axle 102
Under being to the direction for pointing to lower cover 122 by upper lid 121, it is upper that the direction of upper lid 121 is pointed to by lower cover 122.
Output shaft 20 is at least partially disposed in receiving portion 12, output shaft 20 also from the side of lower cover 122 extend downwardly to
Outside receiving portion 12, attachment 42 is attached to output shaft 20 and extend out at the part outside receiving portion 12.
Shield 30 is used for the caused chip in the course of the work of backstop hand-hold power tool 100, therefore, in output shaft
During 20 installation tool annex 42, shield 30 is upwardly into few progress part to attachment 42 in the week around first axle 102
Surround.Specifically, shield 30 can be removably attached to housing 10, and for mounting strap 30, housing 10 is also formed with
For receiving the acceptance division 123 of simultaneously mounting strap 30, acceptance division 123 is formed by lower cover 122.Shield 30 includes：Shield body 31,
Kink 32 and connecting portion 33, wherein shield body 31 and kink 32 are separately positioned on the both sides of connecting portion 33.Shield body
31 are used to carry out part encirclement to attachment 42, and connecting portion 33 is cylindric, remote shield of the kink 32 from connecting portion 33
The side of body 31 extends radially outward.The inner surface of connecting portion 33 is also formed with radially inwardly extending radial protrusion
331, corresponding, formed with annular groove 123a, radial protrusion 331 can be embedded in annular groove 123a and can be acceptance division 123
Annular groove 123a inner circumferentials rotate.Acceptance division 123 is also formed with the connectivity slot 123b, connectivity slot 123b connected with annular groove 123a
Annular groove 123a can be at least communicated in the axial direction, radial protrusion 331 can slide into annular groove 123a along connectivity slot 123b,
So as to which in the presence of annular groove 123a and radial protrusion 331, the axial location of shield 30 is fixed.
In addition, in order to fix the circumferential position of shield 30, hand-hold power tool 100 also includes being used to lock the phase of shield 30
Locking piece 43 to acceptance division 123 with first axle 102 for the rotation of axle, locking piece 43 is formed with housing 10 can be with second axis
103 be axle rotation connection, locking piece 43 with respect to housing 10 rotates when at least can turn to lock shield 30 relatively acceptance division 123
The first position of rotation and release shield 30 are relative to the second place that acceptance division 123 rotates.Wherein, locking piece 43 is with respect to housing
10 second axis 103 rotated are perpendicular to the direction of first axle 102 that output shaft 20 rotates, and locking piece 43 is with respect to 10 turns of housing
The direction of first straight line 101 that dynamic second axis 103 also extends with handle portion 11 is crossed to form one and is more than 0 degree less than or equal to 90
The angle of degree, furthermore, locking piece 43 extend relative to the second axis 103 that housing 10 rotates perpendicular to handle portion 11
The direction of one straight line 101.The structure of the locking piece 43 is simple and can allow for shield 30 to be rotated relative to housing 10, so as to which user can
Convenient dismounting shield 30 and the position that the relative housing 10 of shield 30 can be adjusted.
Specifically, multiple holes 321 are also formed with kink 32, multiple holes 321 are along the circumference around first axle 102
Arrangement, each hole 321 also penetrate kink 32 along the direction parallel to first axle 102.Housing 10 forms fluted 123c, should
Groove 123c is further arranged on lower cover 122, and locking piece 43 is that axle is spindle rotationally arranged in groove with second axis 103
In 123c, groove 123c notch edge extends downwardly parallel to the direction of first axle 102.Locking piece 43 also forms and extend out to groove
Locking projections 431 outside 123c, locking projections 431 extend along parallel to the direction of first axle 102 towards shield 30, locking projections
431 can be embedded in hole 321.When locking projections 431 are embedded in hole 321, locking piece 43 locks the relative reception of shield 30
The rotation in portion 123, so that the circumferential position of shield 30 is fixed.
Furthermore, one end of locking piece 43 is spindle rotationally arranged in groove 123c, the other end forms locking projections
431, one end that locking piece 43 forms locking projections 431 is also associated with bias piece 44, and bias piece 44 biases locking piece 43 by second
It is positioned against first position motion.So, alignd when shield 30 turns to hole 321 with respect to acceptance division 123 with locking projections 431
When, in the presence of bias piece 44, locking piece 43 is that axle is moved from the second place to first position with second axis 103, is locked
Projection 431 is embedded in downwards in hole 321 along the direction parallel to first axle 102, so that shield 30 is with respect to housing 10
Rotate locked.In addition, locking projections 431 also include an inclined-plane 431a contacted with the hole wall in hole 321, inclined-plane 431a institutes
Plane and first axle 102 tilt and intersect, and the plane where inclined-plane 431a is also parallel to each other with second axis 103,
So, when user applies the power for causing shield 30 to be rotated relative to acceptance division 123 to shield 30, inclined-plane 431a will cause lock tab
Play 431 and skid off corresponding hole 321, and when shield 30 turns to suitable position, at this moment in the presence of bias piece 44, locking
Projection 431 will be embedded in another hole 321, so that shield 30 is locked again relative to the rotation of acceptance division 123.
In the present embodiment, the number of locking piece 43 is 2, and housing 10 is formed with two groove 123c, and two locking pieces 43 are also
On the Central Symmetry of first axle 102, so that what shield 30 can be more stable is attached to housing 10.
General principle, principal character and advantage of the present utility model has been shown and described above.The technical staff of the industry
It should be appreciated that above-described embodiment does not limit the utility model in any form, it is all by the way of equivalent substitution or equivalent transformation
The technical scheme obtained, all falls within the scope of protection of the utility model.
