[0023] The present invention will be further described in detail below with reference to the embodiments given in the accompanying drawings.

[0024] like Figures 1 to 5As shown, an electric lifting device provided in this embodiment includes a first vertical pole 1, a second vertical pole 2 and a third vertical pole 3. The first vertical pole 1 is provided with an electric drive mechanism 11 and a manual drive mechanism 12. The second vertical pole 2 is provided with a rack 21 extending along its length direction. The top of the second vertical pole 2 is provided with a guide slide 22. The second vertical pole 2 extends into the first vertical pole 1. When the electric drive mechanism 11 acts on the rack 21, the second vertical pole 2 is driven to move up and down relative to the first vertical pole 1 in the vertical direction. The third vertical pole 3 extends into the second vertical pole 2. It also includes a traction belt 4. The traction belt One end of 4 is fixed on the manual drive mechanism 12, and the other end of the traction belt 4 extends through the guide slide seat 22 and then penetrates from the upper end of the second vertical pole 2 and extends downward to be fixed to the bottom of the third vertical pole 3. The traction belt 4 can be made of a chain, a pull rope or other materials. Driven by the second vertical pole 2, the third vertical pole 3 follows it to move up and down in the vertical direction relative to the first vertical pole 1. The first vertical pole 1, the second vertical pole 2 and the third vertical pole 3 are on the same vertical line. The three being on the same vertical line can enable the electric lifting device to reach the maximum rising height, so that it can be applied to various different working occasions.

[0025] In this embodiment, a first opening 13 is provided at the upper end of the front side wall of the first upright pole 1 to partially expose the rack 21 . A fixing seat 14 is provided on the outer side of the first opening 13 .

[0026] In this embodiment, the electric drive mechanism 11 includes a motor 111 and a reduction mechanism 112 connected to the motor 111. The output shaft 1121 of the reduction mechanism 112 is laterally inserted into the fixed seat 14 and is rotationally connected thereto. The output shaft 1121 of the reduction mechanism 112 is provided with a gear 1122 that meshes with the rack 21.

[0027] In this embodiment, the electric drive mechanism 11 also includes a first controller 113. The motor 111, the deceleration mechanism 112 and the first controller 113 are arranged on the same side of the first vertical pole 1. The first controller 113 is arranged below the motor 111. The first controller 113 is provided with a first forward button 1131, a first stop button 1132, a first reverse button 1133 and a speed adjustment knob 1134.

[0028] When the device needs to rise, press the first forward button 1131, the motor 111 starts to drive the output shaft 1121 of the reduction mechanism 112 to rotate forward, and the gear 1122 rotates clockwise to drive the rack 21 to rise, that is, the second vertical pole 2 rises. At the same time as the second vertical pole 2 rises, the guide slide 22 rises with the traction belt 4, that is, the third vertical pole 3 follows it to rise. When it rises to a certain height, you can press the first stop button 1132 to stop rising. Similarly, when the device needs to descend, press the first reverse button 1133 to achieve descent. When the ascent rate needs to be adjusted, rotate the speed control knob 1134 to adjust the speed of ascent.

[0029] In this embodiment, the manual drive mechanism 12 includes a rotating part 121 rotatably connected to the fixed seat 14 and an operating rod 122 fixedly connected to the rotating part 121. A second controller 123 is provided at the end of the operating rod 122 away from the rotating part 121. The second controller 123 is provided with a second forward button 1231, a second stop button 1232 and a second reverse button 1233.

[0030] After using the electric drive mechanism 11, when the height needs to be adjusted, the manual drive mechanism 12 can be used, and the operating lever 122 can be gripped and rotated downward. When one end of the traction belt 4 moves downward, the other end of the traction belt 4 will rise, thereby driving the third vertical pole 3 to rise, completing the drilling operation, improving work efficiency, and increasing drilling accuracy.

[0031] In this embodiment, the front and rear openings of the guide slide seat 22 are interconnected, and a roller 221 is provided between the two side walls of the guide slide seat 22. One end of the traction belt 4 is fixed to the end of the rotating part 121 close to the operating rod 122, and the other end of the traction belt 4 extends into the guide slide seat 22 and passes through the roller 221. The roller 221 is provided to reduce the friction between the traction belt 4 and other objects when the traction belt 4 rises, so that the second vertical pole and the third vertical pole 3 can rise more smoothly, and at the same time, the service life of the traction belt 4 is increased.

[0032] In this embodiment, the third vertical pole 3 is provided with an open groove 31 along the length direction. The open groove 31 is open to the front side. The traction belt 4 passes through the guide slide seat 22 and then enters the open groove 31 and extends downward to be fixedly connected to the bottom of the third vertical pole 3.

[0033] In this embodiment, a cross connecting seat 15 is provided at the bottom of the first vertical pole 1. The cross connecting seat 15 is composed of four cross bars 151. A sliding rod 152 is inserted into each cross bar 151. A roller 153 is provided at the bottom of the end of each sliding rod 152 away from the cross bar 151, which is convenient for moving when punching to find the punching position and is easy to install and disassemble.

[0034] like Figure 6 As shown, an electric drill punching device includes an electric drill device 5, a fixing rod 6 and an electric lifting device as described above. The electric drill device 5 is fixedly connected to the fixing rod 6, and the lower end of the fixing rod 6 is fixedly connected to the upper end of the third vertical pole 3.

[0035] The above description is only a preferred embodiment of the present invention and should not be used to limit the scope of implementation of the present invention. In other words, simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the utility model description are still within the scope of the present utility model patent.
