Description

Technical Field

[0001] This utility model relates to the field of electric hammer drill technology, and in particular to an electric hammer drill with anti-deviation function. Background Technology

[0002] A hammer drill is an electric tool that combines rotation and impact functions. It is mainly used to drill holes in hard materials such as concrete and brick. It generates high-frequency impact force through an internal hammering mechanism, while the drill bit rotates, thereby achieving efficient drilling.

[0003] Existing electric hammer drills achieve drilling operations by hammering. However, they lack a limiting structure, which causes the drill rod to deviate during drilling, damaging the rod. Furthermore, the existing electric hammer drills have a one-piece structure, making it inconvenient for workers to replace the rod and resulting in low flexibility. Summary of the Invention

[0004] To overcome the problems of conventional electric hammer drills, which achieve drilling operations by hammering, but lack a limiting structure during use, causing the drill rod to deviate and damage the rod during drilling, and the fact that the existing electric hammer drills have a one-piece structure, making it inconvenient for workers to replace the rod and resulting in low flexibility.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electric hammer drill with anti-deviation function, comprising a mounting base; a connecting base is mounted on the left end of the mounting base, a connecting rod is slidably connected inside the connecting base, an electric hammer drill rod is mounted on the left end of the connecting base, a spiral groove is formed on the surface of the electric hammer drill rod, side plates are provided at the front and rear ends of the surface of the electric hammer drill rod, a top plate is mounted on the upper end of the two side plates, a limiting component is mounted on the surface of the side plates, two limiting components are provided, and a fixing component is mounted on the surface of the two side plates.

[0006] Preferably, the fixing assembly includes a fixing seat, a fixing rod, a connecting ring, and a first spring. The fixing seat is mounted on the surface of the two side plates, and the fixing rod is slidably connected inside the fixing seat. The fixing rod is arranged in a ring with six rods.

[0007] Preferably, a connecting ring is installed at the right end of the fixing rod, and a first spring is sleeved on the surface of the fixing rod. One end of the first spring is fixedly connected to the fixing seat, and the other end of the first spring is fixedly connected to the connecting ring.

[0008] Preferably, the limiting component includes a first mounting bracket, a second mounting bracket, a limiting rod, a pull plate, a telescopic rod, and a second spring. The surface of the side plate is provided with a sliding groove, and a slider is slidably connected inside the sliding groove.

[0009] Preferably, a first mounting bracket is installed at the upper end of the slider, and a second mounting bracket is installed at the lower end of the slider. A limit rod is slidably connected inside the first mounting bracket, and a pull plate is installed at the upper end of the limit rod. The limit rod and the slider are slidably connected.

[0010] Preferably, telescopic rods are installed at the left and right ends of the upper end of the first mounting bracket. The upper end of the telescopic rod is fixedly connected to the pull plate. A second spring is sleeved on the surface of the telescopic rod. One end of the second spring is fixedly connected to the pull plate, and the other end of the second spring is fixedly connected to the first mounting bracket.

[0011] Preferably, a positioning block is installed on the inner surface of the slider, the surface of the positioning block is provided with a positioning groove, the surface of the connecting rod is provided with a mounting groove, and the dimensions of the positioning block and the mounting groove are adapted to each other.

[0012] Preferably, a positioning seat is installed on the surface of the connecting rod, and two positioning seats are provided. A positioning rod is slidably connected inside the positioning seat.

[0014] Compared with the prior art, the beneficial effects of this utility model are: When the electric hammer drill is working, the connecting seat drives the connecting rod to move, causing the slider to slide along the groove direction. This controls the first mounting bracket and the second mounting bracket to push the connecting ring, causing the connecting ring to drive the fixed rod to slide in the fixed seat. This achieves a limiting connection between the fixed rod and the work site, preventing the device from shifting and causing damage, and increasing the practicality of the device. When the operator needs to replace the hammer drill rod, the pull plate can be pulled to remove the limit rod from the slider, and the handle can be pulled to remove the positioning rod from the positioning slot, thereby separating the positioning block from the connecting rod and separating the slider from the connecting rod, so that the operator can replace the hammer drill rod. Then, under the action of the second spring, the telescopic rod is retracted, thereby resetting the limit rod and engaging it with the slider, increasing the flexibility of the device.

[0028] Working principle: According to Figure 1 , Figure 2 , Figure 4 and Figure 5 When the electric hammer drill is working, the fixed seat 7 is first attached to the drilling surface, so that the fixed rod 71 slides in the fixed seat 7 and pushes out the connecting ring 72. Then, when the electric hammer drill rod 4 moves, it drives the connecting seat 2 to move synchronously, so that the connecting rod 3 drives the slider 9 to slide along the direction of the slide groove 8, thereby synchronously driving the first mounting bracket 51 and the second mounting bracket 52 to slide on the surface of the side plate 5. When drilling, the first mounting bracket 51 and the second mounting bracket 52 push the connecting ring 72, thereby pushing the fixed rod 71 to slide in the fixed seat 7, so as to realize the limiting of the fixed rod 71 and the drilling surface, avoid the displacement of the electric hammer drill rod 4, and increase the practicality of the device. according to Figure 2 , Figure 3 , Figure 6 and Figure 7When maintenance is required, the staff can pull the pull plate 54 to pull the limiting rod 53 out of the slider 9, and simultaneously pull the handle 34 to pull the positioning rod 33 out of the positioning groove 101, thereby removing the positioning block 10 from the mounting groove 31, and controlling the slider 9 to be removed from the slide groove 8, which facilitates the staff to perform replacement and maintenance operations. After the replacement and maintenance are completed, under the action of the third spring 35, the positioning rod 33 returns to its original position and engages with the positioning block 10, and under the action of the second spring 56, the telescopic rod 55 retracts to drive the limiting rod 53 to engage with the slider 9, thereby realizing the limiting connection between the slider 9 and the connecting rod 3, which increases the convenience of the device.
