Abstract
The utility model relates to a borer for a waistband, comprising the borer body, movable clamping plates, large shafts, small shafts, a linear guide rail, and the panel of the borer body. The utility model is used for the waistband and is characterized in that the large shaft used by the borer for the waistband moves along the linear guide rail. When the waistband is used, one end of the band body of the waistband is fixed with the movable clamping plates; the other end passes through an interstice between the back side of the panel of the borer body and the large shaft. The large shaft can be moved along a linear guide rail by hands for making the interstice be smaller than the thickness of the band body of the waistband. The band body of the waistband is fixed. When the band body of the waistband is loosen, the opposite direction force takes back the large shaft for making the interstice be larger than thickness of the band body of the waistband; then the band body of the waistband can be loosen.
Description
The utility model relates to a kind of waistband hammer drill.
Waistband is made up of waistband belt body and Borer for belt.Borer for belt is slided by pricker body, ambulatory splint, macro-axis, little axle and macro-axis and forms with guide rail.During use, the waistband belt body passes the gap of Borer for belt pricker dignity backboard face and big between centers, with hand macro-axis is moved along guide rail, makes this gap less than waistband belt body thickness, and the waistband belt body promptly is fixed.Originally the Borer for belt macro-axis of Shi Yonging is to move along curvilinear guide, curvilinear guide slope to a point is all different, this Borer for belt requires very high to waistband belt body thickness range, after macro-axis must be moved past the curvilinear guide peak, at this position locking waistband belt body, the waistband belt body just can be fixed.If macro-axis moves to the curvilinear guide crooked position and just locks the waistband belt body, so under unusual external force effect, frictional force between the tongue and groove of macro-axis and waistband belt body is not enough to stop macro-axis to glide along curvilinear guide, thereby the waistband belt body is unclamped, influence the use of waistband, change this situation, can increase the thickness of Borer for belt, lock the waistband belt body after making macro-axis can both move past peak at every turn, but waistband is the harness that is used for human body, Borer for belt thickness is too thick not all right, and is also not attractive in appearance, so this way is inapplicable.
Task of the present utility model provides a kind of novel Borer for belt, on the basis that does not change original Borer for belt thin type structure, change curvilinear guide into line slideway, macro-axis is moved along line slideway, it can be easily fixing waistband belt body, and solved the problem that original Borer for belt fixedly unclamps behind the waistband belt body easily, thereby different waistline human needs have been satisfied.
Task of the present utility model is finished as follows: waistband belt body one end is fixed on the ambulatory splint, the other end passes the gap of Borer for belt pricker dignity backboard face and big between centers, after the waistband tape body length is suitable, move macro-axis with hand along line slideway, waistband belt body thickness difference, macro-axis will be locked the waistband belt body and the position that rests in the line slideway is also different, the slope of line slideway every bit is identical, and slope is less, the sliding force that macro-axis produces under this slope is less, therefore, as long as make the thickness of gap less than the waistband belt body, macro-axis can be easily on line slideway fixing waistband belt body.Under unusual external force effect, the frictional force between the tongue and groove of macro-axis and waistband belt body is enough to stop macro-axis to glide, thereby locks the waistband belt body securely greater than the sliding force that macro-axis produces under this slope.When loosening one's waistband belt body, as long as firmly return macro-axis in the other direction, make the thickness of gap greater than the waistband belt body, the waistband belt body can loosen.
The utility model has the advantages that simple in structure, easy to use.
Below by means of accompanying drawing an embodiment of the present utility model is illustrated.
Fig. 1 is the transverse sectional view of Borer for belt.
Fig. 2 is the front view of the macro-axis that uses in the Borer for belt.
Fig. 3 is 4:1 for macro-axis among Fig. 2 along the cutaway view ratio of A-A line.
With reference to Fig. 1, this Borer for belt comprises pricker body (1), ambulatory splint (2), macro-axis (3), little axle (4), line slideway (5), pricker dignity plate (6).
Pricker body (1) is connected by little axle (4) with ambulatory splint (2), the macro-axis (3) that there is line slideway (5) at pricker body (1) middle part and moves along line slideway (5), macro-axis (3) preferably adopts structure as shown in Figure 2, pricker dignity plate (6) is made with plastic material, be bonded on the pricker body (1), attractive in appearance to increase.
During operation, waistband belt body one end is fixed on the ambulatory splint (2), the other end passes the gap between pricker dignity plate (6) back side and macro-axis (3) from left to right, waistband belt body girth is made by oneself according to each one waistline, mobile then macro-axis (3), as long as can make the thickness of gap less than the waistband belt body, macro-axis (3) fixing waistband belt body on line slideway (5).When loosening one's waistband belt body, as long as firmly return macro-axis (3) in the other direction, make the thickness of gap greater than the waistband belt body, the waistband belt body can loosen.Though this utility model simply but very effective.
Claims (3)
1, a kind of Borer for belt is made up of pricker body (1), ambulatory splint (2), macro-axis (3), little axle (4), line slideway (5), pricker dignity plate (6), it is characterized in that macro-axis (3) moves along the line slideway (5) in the pricker body (1).
2, Borer for belt according to claim 1 is characterized in that macro-axis (3) has tongue and groove.
3, Borer for belt according to claim 1 is characterized in that pricker dignity plate (6) is plastic material.
