DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figures 1 to 4 The utility model provides a technical solution: an assembled impact drill, comprising an impact drill body 1, a drill bit 2 is arranged at the bottom end of the impact drill body 1, operating handles 3 are symmetrically fixed on both sides of the top of the impact drill body 1, a quick assembly mechanism is arranged between the drill bit 2 and the impact drill body 1, and a gripping anti-slip mechanism is arranged on the surface of the operating handle 3. The quick assembly mechanism includes: a reset component,

[0025] A connecting assembly, which is arranged at the connection between the drill bit 2 and the impact drill body 1;

[0026] A guide assembly, the guide assembly being arranged inside the connecting assembly;

[0027] A limit assembly, which is arranged on the inner side of the connecting assembly;

[0028] A positioning assembly is arranged on the side of the impact drill body 1 and connected to the limiting assembly.

[0029] In this embodiment, preferably, the connecting assembly includes a connecting groove 100 opened at the bottom end of the impact drill body 1 and a connecting rod 101 fixed to the top end of the drill bit 2. The drill bit 2 can be connected to the impact drill body 1 by engaging the connecting rod 101 with the connecting groove 100.

[0030] In this embodiment, preferably, the guide assembly includes a guide groove 200 opened at the top of the connecting rod 101 and a guide block 201 fixed inside the connecting groove 100. The guide block 201 is engaged with the guide groove 200 to facilitate the connection between the connecting rod 101 and the connecting groove 100 to play a docking guide role.

[0031] In this embodiment, preferably, the limiting assembly includes limiting grooves 300 symmetrically opened on both sides of the connecting rod 101 and built-in grooves 301 symmetrically opened on both sides of the inner wall of the connecting groove 100, and a limiting block 302 is arranged inside the built-in groove 301. The limiting block 302 is engaged and connected with the limiting groove 300, so that the connecting rod 101 can be temporarily limited inside the connecting groove 100.

[0032] In this embodiment, preferably, the reset component includes a slide groove 400 symmetrically opened on both sides of the inner wall of the built-in groove 301 and a slider 401 symmetrically fixed on both sides of the limit block 302. The slider 401 is slidably connected to the slide groove 400. A telescopic spring 402 is connected between the slider 401 and the slide groove 400, which can drive the slider 401 to reset and slide inside the slide groove 400, and drive the limit block 302 to pop out from the inside of the built-in groove 301.

[0033] In this embodiment, preferably, the positioning assembly includes a positioning hole 500 opened at the end of the limit block 302 and a screw hole 501 extending through the interior of the built-in groove 301. A positioning screw 502 extending through the interior of the screw hole 501 and connected to the positioning hole 500 is provided on the side of the impact drill body 1. By screwing the positioning screw 502 and the positioning hole 500 together for fixation, the limit block 302 can be firmly positioned, and the drill bit 2 and the impact drill body 1 can be firmly assembled and fixed together.

[0034] In this embodiment, preferably, the gripping anti-slip mechanism includes a rubber ring 600 sleeved on the surface of the operating handle 3 and anti-slip stripes 601 fixed at equal distances on the surface of the rubber ring 600, so as to prevent slipping when gripping the operating handle 3.

[0035] Working principle and use process of the utility model: When the drill bit 2 needs to be connected to the impact drill body 1, the drill bit 2 is first fitted with the end of the impact drill body 1, so that the connecting rod 101 is embedded in the inner part of the connecting groove 100 to squeeze the limit block 302, and the limit block 302 is squeezed into the inner part of the built-in groove 301 by external force, and drives the slider 401 to slide inside the slide groove 400 to squeeze the telescopic spring 402 to deform, so that the connecting rod 101 can be completely stuck in the inner part of the connecting groove 100, and the guide block 201 is docked with the guide groove 200. The limit block 302 plays a guiding role. At this time, the limit block 302 is reset from the inside of the built-in groove 301 and popped out and stuck into the inside of the limit groove 300 under the action of the telescopic spring 402, so as to temporarily limit the connecting rod 101. Then, the positioning screw 502 is tightened and rotated inside the screw hole 501 to be screwed and fixedly connected with the positioning hole 500. The limit block 302 can be firmly positioned to facilitate the assembly and connection of the drill bit 2 and the impact drill body 1. When it is necessary to hold the operating handle 3 to operate the impact drill body 1, the rubber ring 600 and the anti-slip stripe 601 can play a role in holding and preventing slipping.
