DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-3 A handheld concrete vibrator comprises a vibration motor 1, one end of which is connected to a vibration rod 5 through a transmission hose 4, a first handle 2 is fixedly installed on the outside of the vibration motor 1, a finger grip groove is provided on the first handle 2, and a base 3 is fixedly installed on the outside of the vibration motor 1. The first handle 2 is used to facilitate the lifting and moving of the vibration motor 1, and at the same time, the contact area between the vibration motor 1 and the working bottom surface is increased through the base 3 to prevent it from tipping over due to vibration.

[0023] A clamp seat 6 is installed on the transmission hose 4, and a second handle 7 is fixedly installed on the top surface of the clamp seat 6. A pressing plate 9 is slidably connected to the bottom surface of the second handle 7. Both ends of the pressing plate 9 pass through the second handle 7 and are installed with transmission rods 8, and each transmission rod 8 passes through the second handle 7 and extends into the clamp seat 6.

[0024] A first spring 10 is installed between the top surface of the pressing plate 9 and the bottom surface of the second handle 7, a bottom plate 11 is installed at the bottom ends of the two transmission rods 8, a slide groove is provided in the clamp seat 6, and the bottom plate 11 is slidably connected in the slide groove, through the tensile force of the first spring 10. When the user does not press the pressing plate 9, the transmission rod 8 can still be lifted, and then the arc clamping plate 13 set on the bottom plate 11 is abutted against the transmission hose 4 through the transmission rod 8, so as to prevent the clamp seat 6 from sliding on the transmission hose 4 at will; at the same time, when the user holds the pressing plate 9 and the second handle 7, the pressing plate 9 is lifted upward by the user's grip, and the greater the grip of the user, the greater the clamping force of the arc clamping plate 13 on the transmission hose 4, and at the same time, because the pressing plate 9 extends upward and passes through the second handle 7; when the clamp seat 6 is moved, the pressing plate 9 can be directly pressed from above the second handle 7, so as to reduce the clamping force of the arc clamping plate 13 on the transmission hose 4, so as to facilitate movement.

[0025] Two arc-shaped clamping plates 13 are symmetrically arranged on the top surface of the bottom plate 11 and the clamping seat 6, and the arc-shaped clamping plates 13 are against the transmission hose 4. The side wall of each arc-shaped clamping plate 13 is bonded with an anti-skid pad 15, and the anti-skid pad 15 is made of rubber. A circular through groove 14 is opened in the clamping seat 6. Two telescopic rods 12 are symmetrically installed on the top surface of the bottom plate 11 and the side wall of the circular through groove 14, and each arc-shaped clamping plate 13 is fixedly installed on the telescopic rod 12 at a corresponding position. The telescopic rod 12 includes a sliding rod and a sliding seat, and the sliding rod is slidably connected in the sliding seat, and one end of the sliding rod is fixedly connected to the arc-shaped clamping plate 13 at a corresponding position. A second spring 16 is jointly installed between the bottom wall of the sliding seat and the bottom surface of the sliding rod. Through the action force of the second spring 16, the arc-shaped clamping plate 13 can adapt to the diameter length of the transmission hose 4, so that the clamping seat 6 can be used on transmission hoses 4 of different specifications.

[0026] When the utility model is used, the staff can lift the vibration motor 1 through the first handle 2 to facilitate the movement of the vibration motor 1. At the same time, the contact area of ​​the vibration motor 1 with the working bottom surface is increased through the base 3 to prevent the vibration motor 1 from tipping over due to vibration.

[0027] Then, the staff can hold the second handle 7 and the pressing plate 9, and then through the staff's grip force, the second handle 7 on the pressing plate 9 is brought closer, and then the bottom plate 11 is lifted through the transmission rod 8, and the arc-shaped clamping plate 13 provided on the top surface of the bottom plate 11 and the arc-shaped clamping plate 13 installed on the inner wall of the circular through groove 14 are used to clamp the transmission hose 4 together, and the greater the grip force, the greater the clamping force, and the anti-slip pad 15 provided on the arc-shaped clamping plate 13 increases the friction between the arc-shaped clamping plate 13 and the transmission hose 4, which is convenient for the staff to hold the transmission hose 4.

[0028] It is worth noting that the outer sides of the arc-shaped clamping plates 13 are all mounted on the telescopic rod 12 , and a second spring 16 is installed inside the telescopic rod 12 , thereby pushing the arc-shaped clamping plates 13 to clamp the transmission hoses 4 of different specifications.

[0029] It is worth mentioning that the pressing plate 9 extends upward and passes through the second handle 7. When the clamping seat 6 is moved, the pressing plate 9 can be pressed directly from above, thereby reducing the clamping force of the arc clamping plate 13 on the transmission hose 4, thereby facilitating movement, and adjusting the hand-holding position of the transmission hose 4, thereby adjusting the depth of the vibrating rod 5 in the concrete.
