The specific embodiment

Below, by reference to the accompanying drawings and the specific embodiment, the utility model is described further:

As shown in Figure 1, manual catch means for the rotating shaft of a kind of stage Adjustable head lamp of the utility model, it comprises the synchronous lock-bit plate 1 that is installed in the lamp holder rotating shaft, and be fixed on mount pad 2 on the stage Adjustable head lamp body, mount pad 2 is tabular, be fixed with on its outer surface a rotating shaft 23 perpendicular to its plate face, be articulated with leader 3 in this rotating shaft 23, the Handheld Division 31 and the support end 32 that grip for staff when handle 3 forms respectively an operation in the both sides of its pivot center, outer bending forms a gripper shoe 21 to mount pad 2 near a side direction of support end 32, offer a mounting groove 22 on the gripper shoe 21, be provided with a support bar 5 between gripper shoe 21 and the support end 32, concrete is, the cross-under of the outboard end activity of support bar 5 is in mounting groove 22, its medial extremity then with the docking of support end 32 activities, be arranged with a spring 6 on the support bar 5, this spring 6 is limited between the medial extremity and the gripper shoe 21 on the mount pad 2 of support bar 5, under the effect of spring 6 elastic stresses, the medial extremity of support bar 5 provides the active force of a compression support end 32, it should be noted that, the width of above-mentioned mounting groove 22 is greater than the width of support bar 5, should guarantee that support bar 5 can penetrate and pass from mounting groove 22, to guarantee that also handle 3 is when rotating, after 32 pairs of support bars 5 of support end applied active force, support bar 5 can rotate with respect to gripper shoe 21.Between the pivot center of above-mentioned handle 3 and support end 32, a slide block 4 is installed, the edge of lock-bit plate 1 is provided with a lock-bit groove 11 corresponding with this slide block 4, when handle 3 rotates, slide block 4 can embed lock-bit groove 11 or break away from from lock-bit groove 11, concrete is, between its pivot center and support end 32, offer a waist hole 33 on the handle 3, be fixed with a bolt 41 on the slide block 4, these bolt 41 cross-under are in waist hole 33, bolt 41 is connected with nut 42 away from the end that an end of slide block 4 passes waist hole 33, because bolt 41 can the 33 interior activities in the waist hole, can guarantee handle 3 when 4 motion of band movable slider, slide block 4 is along straight-line.

Be socketed with a lining bar 43 between handle 3 and mount pad 2 at bolt 41.

Referring to Fig. 2, under lamp holder rotating shaft state free to rotate when not locked (be lamp holder rotating shaft), the medial end of support bar 5 is in the maximum angle that outwards rotates with respect to gripper shoe 21, this moment is under the elastic stress of spring 6, because the angle of spring 6, elastic stress that it produces produce one with support end 32 to the component that promotes away from lock-bit plate 1, and locked under this state at handle 3, be that handle 3 is not subjected in the situation of external force, can not rotate, this moment, the stage Adjustable head lamp was in normal duty.When needs are carried, the Handheld Division 31 of outside swing handle 3, the support end 32 of handle 3 namely inwardly rotates, and support end 32 promotes support bar 5, make support bar 5 pass the protruding ends distance of mounting groove 22 and rotate with respect to gripper shoe 21, when support bar 5 turns to inside maximum angle, spring 6 also turns to corresponding angle thereupon, at this moment, because spring 6 residing angles, the elastic stress that it produces produces a separation that support end 32 is promoted to close lock-bit plate 1, and locked under this state, when handle 3 rotate in place, slide block 4 was thereupon mobile, and be embedded in the lock-bit groove 11, under this state, slide block 4 can lock lock-bit plate 1, and in the situation that is not subjected to external force, handle 3 can not rotate, and namely slide block 4 will keep the position of this locking.

For a person skilled in the art, can make other various corresponding changes and distortion according to technical scheme described above and design, and these all changes and distortion should belong within the protection domain of the utility model claim all.
