[0002] With the rapid development of the economy and the acceleration of urbanization, the number and scale of public buildings are constantly expanding, and their storey heights are also showing an increasing trend, especially during the decoration stage. When drilling holes in ceiling angle steels, an operating frame is required to provide a stable working platform for construction workers. However, if the common operating frame is large in scale and is used frequently, the frame needs to move with the operator. When the frame moves, the staff needs to get down from the frame to the ground, which is time-consuming and laborious. In addition, high-altitude operations require corresponding safety protection measures, which seriously reduces construction efficiency. Summary of the invention

[0003] The purpose of the utility model is to provide a retractable top plate punching combination device in order to solve the above-mentioned problem. The telescopic structure is formed by the support rod and the connecting rod, which is convenient for cooperating with the electric hammer on the second support rod to drill holes on the ceiling angle steel. The structure is simple. At the same time, when the second support rod moves upward during work, the second roller and the support block are alternately supported by the support block, thereby improving the stability of construction.

[0004] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0005] A retractable top plate punching assembly device comprises a first support rod and two connecting rods, and also comprises a first movable structure and a second movable structure. The rod body of the first support rod is rotatably provided with a handle, a second support rod is rotatably provided on one side of the handle, an electric hammer is provided on the top side of the second support rod, the connecting rod is rotatably provided between the first support rod and the second support rod, a supporting structure is provided inside the lower end of the first support rod, and the supporting structure and the first movable structure are connected to each other via a connecting structure.

[0028] See also Figure 1-Figure 8 As shown, the utility model provides a retractable top plate punching assembly device, including a first support rod 1 and two connecting rods 5, and also including a first moving structure 6 and a second moving structure 9, which facilitates the movement of the first support rod 1. The rod body of the first support rod 1 is rotatably provided with a handle 3, and one side of the handle 3 is rotatably provided with a second support rod 2. By using the parallelogram principle, the longitudinal and transverse wooden beams are hingedly connected by tension bolts to make a simple retractable combination hammer. The vertical two long wooden beams are the first support rod 1 and the second support rod 2. A wooden beam stands on the floor as the first support rod 1, and an electric hammer 4 is fixed at the end of a wooden beam as the second support rod 2. The horizontal three short wooden beams, the middle one is slightly longer, which is the handle 3, and the two connecting rods 5 limit the moving position of the second support rod 2, which serves as a handle for operating and adjusting the telescopic movement. When the handle 3 is pressed downward, the "combination hammer" extends, and when the handle 3 is pushed upward, the position of the combination hammer drops. An electric hammer 4 is provided on the top side of the second support rod 2, which is convenient for drilling holes on the ceiling angle steel. This belongs to the prior art and will not be described in detail. The connecting rod 5 is rotatably arranged between the first support rod 1 and the second support rod 2. The connecting rod 5 is used to limit the moving position of the second support rod 2. A support structure 8 is provided inside the lower end of the first support rod 1. The support structure 8 is used to facilitate the connection of the first movable structure 6. The support structure 8 and the first movable structure 6 are connected to each other through a connecting structure 10.

[0029] The support structure 8 includes two support frames 801, and the support frame 801 is internally rotatably provided with a first rotating rod 802. The first movable structure 6 includes a support block 601, and a connecting frame 602 is fixedly provided in the vertical direction of the support block 601. The connecting frame 602 is internally rotatably provided with a first roller 603, and a stopper 604 is fixedly provided on one side of the connecting frame 602. A push plate 11 is fixedly provided at the lower end of the second support rod 2, and a bevel groove is provided inside the push plate 11 to facilitate pushing the stopper 604 to move. Through the connecting structure 10, the internal support block 601 of the first movable structure 6 and the first roller 603 on the connecting frame 602 are conveniently alternated. When the second support rod 2 moves upward, the push plate 11 on the second support rod 2 does not squeeze the first movable structure 6, and then the support block 601 on the first movable structure 6 moves through the connecting structure 10, so that the support block 601 and the first roller 603 are alternately supported, so that the support block 601 assists the first support rod 1 in supporting.

[0030] Furthermore, the connecting frame 602 is fixedly arranged on the bottom side of the first support rod 1, and the supporting block 601 is fixedly arranged on the rod body of the first rotating rod 802. When the supporting block 601 and the first roller 603 are alternately moved, the first rotating rod 802 on the supporting block 601 drives the second roller 902 on the second rotating rod 901 to rotate through gear transmission, so as to facilitate the relative movement of the first roller 603 and the second roller 902. When the second support rod 2 is at the bottom, the pushing plate 11 on the second support rod 2 pushes the stopper 604 connected to the connecting frame 602 on the first roller 603, so that the first roller 603 and the supporting block 601 are alternately moved through the first rotating rod 802. Then when the first roller 603 moves to the bottom, the second roller 902 also moves to the bottom of the first support rod 1 through gear transmission, so as to facilitate the movement of the first support rod 1.

[0031] Furthermore, the second movable structure 9 is arranged at the lower end inside the first support rod 1, the first movable structure 6 and the second movable structure 9 are connected to each other through the transmission structure 7, the second movable structure 9 includes a second rotating rod 901 and a second roller 902, the connecting structure 10 includes a first gear 702, a second gear 703 and a shell 701, the first rotating rod 802 is fixedly arranged on one side of the first gear 702, and is rotated by the first gear 702 and the second gear 703, so as to facilitate the control of the first roller 603 and the second roller 902 to rotate relative to each other, when the two first rollers 603 are both at the bottom, the second support rod 2 is at the bottom, which is convenient for the first support rod 1 to move, and when the second support rod 2 is at the top, the support block 601 on the first movable structure 6 and the first roller 603 on the connecting frame 602 are alternately performed, and at this time the support block 601 is perpendicular to the ground, which facilitates the support block 601 to assist the first support rod 1 in supporting,

[0032] Furthermore, the second rotating rod 901 is rotatably arranged inside the second roller 902, and the second rotating rod 901 is fixedly arranged on one side of the second gear 703. When the first roller 603 rotates through the support block 601 on the connecting frame 602, the first gear 702 on the first rotating rod 802 is driven to rotate at the same time, and then the transmission is performed between the first gear 702 and the second gear 703, so that the second roller 902 on the second gear 703 can rotate relatively, so that the first support rod 1 and the second support rod 2 can be driven to move by the first roller 603 and the second roller 902.

[0033] Furthermore, the first gear 702 and the second gear 703 are meshed with each other, and the first gear 702 and the second gear 703 are rotatably arranged inside the shell 701. The transmission is performed by the first gear 702 and the second gear 703, so that the first roller 603 connected to the first rotating rod 802 can move simultaneously with the second roller 902 on the second rotating rod 901.

[0034] Furthermore, the shell 701 is fixedly disposed on the bottom side of the first support rod 1 , and the first gear 702 and the second gear 703 are conveniently supported and protected by the shell 701 .

[0035] Furthermore, when the first roller 603 and the support block 601 are alternately at the bottom, transmission is performed through the first gear 702 and the second gear 703 so that the second roller 902 is also at the bottom of the first support rod 1, and the positions of the first support rod 1 and the second support rod 2 can be adjusted to facilitate transportation and adjustment of the construction position.

[0036] Furthermore, the connecting structure 10 includes a connecting ring 1001, which is fixedly arranged on the rod body of the first rotating rod 802. A reset spring 1002 is fixedly connected between the connecting ring 1001 and the support frame 801 close to the first rotating rod 802. The reset spring 1002 facilitates the resetting of the first rotating rod 802, thereby allowing the support block 601 and the first roller 603 to alternate, making it convenient to assist the first support rod 1 in supporting by the support block 601.

[0037] With the above structure, when the device is used, first, the first support rod 1 is moved by the first moving structure 6 and the second moving structure 9. When it moves to the specified position, the handle 3 is pulled first, so that the handle 3 drives the second support rod 2 to drive the electric hammer 4 to move upward through the connecting rod 5. At the same time, when the second support rod 2 moves upward, the push plate 11 on the second support rod 2 does not squeeze the first moving structure 6. Then the support block 601 on the first moving structure 6 is moved through the connecting structure 10, so that the support block 601 and the first roller 603 are alternately moved. When the second support rod 2 moves upward, the support block 601 assists the first support rod 1 to provide stable support. When the second support rod 2 moves downward, the push plate 11 on the second support rod 2 pushes the stopper 604 on the first moving structure 6, and then the stopper 604 pushes the first roller 603 and the support block 601 through the connecting frame 602, so that the first roller 603 is below the second support rod 2.

[0038] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
