The locking shaft 43 is fixed with arc-shaped convex strips 431 that can abut against the connecting head 41 at intervals. The locking shaft 43 is penetrated through the outer side of the motor output terminal 11 to form a handle; the locking shaft 43 is driven to rotate by rotating the handle, and when the arc-shaped convex strip 431 abuts against the connecting head 41, it plays the role of interference fit, making the connection between the connecting head 41 and the motor output terminal 11 more stable.

[0037] Reference Figure 1 The motor body 1 is connected to the support frame 3 through a rotating structure 5. The rotating structure 5 includes a connecting seat 51 fixed to the bottom of the motor body 1 and an annular seat 52 fixed to the support frame 3. The connecting seat 51 is in the shape of an I. A connecting column with a reduced diameter and inserted into the annular seat 52 is formed in the middle of the connecting seat 51. The bottom of the connecting seat 51 abuts against the bottom of the annular seat 52.

[0038] Reference Figure 1 , 4 The rotating structure 5 also includes a positioning block 53 movably connected to the connecting column, and the inner wall of the annular seat 52 is provided with positioning grooves 521 at intervals in the circumferential direction. The positioning block 53 can be passed through the outside of the connecting column and positioned in the positioning groove 521 corresponding to the inner wall of the annular seat 52, thereby realizing the rotational positioning of the connecting seat 51 and the motor body 1.

A slider 61 inserted into and sliding in the connecting seat 51 is fixed on the driving sleeve 6 to maintain the lateral sliding stability of the driving sleeve 6. The translation of the driving sleeve 6 in the connecting seat 51 can be controlled by rotating the driving rod 54; the lower part of the driving sleeve 6 is fixed to the positioning block 53 by a vertical rod. When the driving sleeve 6 translates, the vertical rod and the positioning block 53 can be translated synchronously to realize the insertion or disengagement of the positioning block 53 on the inner side wall of the annular seat 52, so as to respectively realize the positioning and rotation processes of the motor body 1, so that the use of the concrete vibrator is easier to control.

[0040] Reference Figure 1 , 4 The driving rod 54 includes a movable rod 541 and a mounting rod 542. The mounting rod 542 is connected to the side wall of the connecting seat 51 and can rotate. The rotatable mounting rod 542 cooperates with the driving sleeve 6 to control the translation of the driving sleeve 6; the movable rod 541 is rotatably connected to the end of the mounting rod 542 passing through the outside of the connecting seat 51 through a rotating shaft, so that the movable rod 541 can be bent downward and positioned on the support frame 3, thereby preventing the movable rod 541 from extending too long horizontally and causing obstruction and accidental touch.

When the movable rod 541 is arranged parallel to the mounting rod 542, the block 7 is engaged with the slot 8, thereby fixing the movable rod 541 in a state of extending parallel to the mounting rod 542, thereby improving the stability of the synchronous rotation of the movable rod 541 and the mounting rod 542.

[0042] Reference Figure 1 , 6 The movable rod 541 can be positioned on the support frame 3; a receiving groove 31 for accommodating the movable rod 541 is provided on the support frame 3, and a fixing block 10 for positioning the end of the movable rod 541 is connected to the receiving groove 31 through a spring 9. The fixing block 10 positions the movable rod 541, so that the setting of the spring 9 has a certain shock-absorbing effect on the vibration process of the motor body 1.

[0043] Reference Figure 1 , 6 , a groove 13 is formed at the end of the movable rod 541, and an extension rod 101 is extended on the fixed block 10 to abut against both sides of the movable rod 541, and a protrusion 12 is fixed on the extension rod 101 to be snapped into the groove 13; the movable rod 541 is received in the receiving groove 31 of the support frame 3, so that the movable rod 541 and the support frame 3 are connected to each other, and the extension rod 101 extending from the fixed block 10 abuts against the side wall of the movable rod 541, and then fixed by the cooperation of the protrusion 12 and the groove 13, on the one hand, the movable rod 541 is fixed to improve the stability of the connection between the motor body 1 and the support frame 3, thereby improving the stability of the concrete vibrator during operation; in addition, it should be pointed out that when the movable rod 541 and the mounting rod 542 rotate 360 ​​degrees, the positioning block 53 can complete the disengagement or plug-in process, so as to keep the movable rod 541 always positioned in the receiving groove 31 after rotation.

[0044] The working process of the present application is as follows: when the motor body 1 is rotated, the movable rod 541 is flipped upward to extend parallel to the mounting rod 542, and the clamping block 7 is clamped in the clamping slot 8, and then the mounting rod 542 is rotated to move the driving sleeve 6 in the direction away from the mounting rod 542, driving the positioning block 53 to disengage from the annular seat 52, and at the same time, the driving sleeve 6 abuts against the end of the connecting seat 51 away from the movable rod 541. At this time, the movable rod 541 can be bent downward to avoid accidental touch and obstruction, and then the motor body 1 is rotated to the desired position.
