Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.

The first embodiment is as follows: an improved percussion drill, see fig. 1 to 4, comprising:

the percussion drill comprises a percussion drill body 1, wherein the percussion drill body 1 comprises a shell 11, and a handle 18 is connected outside the shell 11;

shock absorber support 2, shock absorber support 2 is including dismantling the collar 21 of connecting on impact drill body 1, the circumferential connection of collar 21 has a plurality of telescopic links 22, and under the telescopic link 22 natural state, the tip of telescopic link 22 and the drill bit extreme point that strikes drill body 1 are located the coplanar.

When the impact drill is used, firstly, the damping support 2 is abutted to the surface of an impact object, namely, the end part of the telescopic rod 22 and the drill bit are abutted to the impact object at the same time, then the impact drill is started, the impact drill body 1 rapidly vibrates along with the fact that the drill bit drills into the impact object, the telescopic rod 22 converts part of vibration on the impact drill into elastic potential energy of the telescopic rod 22, and the telescopic rod 22 deforms and contracts, so that buffering and damping are achieved, the impact drill can be held by a hand more firmly, and dangerous accidents are reduced; the grip 18 facilitates gripping by both hands of the worker, further improving the stability of the hammer drill.

Specifically, the telescopic rod 22 includes a fixed cylinder 221 and a sliding rod 222 slidably connected to the inside of the fixed cylinder 221, and an elastic member 223 is connected between the sliding rod 222 and the bottom of the fixed cylinder 221. When the telescopic rod 22 is operated, the sliding rod 222 slides in the fixed cylinder 221, thereby compressing the elastic member 223, and the elastic member 223 deforms to absorb the shock of the impact drill body 1.

Specifically, the elastic member 223 is a compression spring.

Specifically, two sliding grooves 12 communicated with the outside are arranged in the shell 11 along a direction perpendicular to the drill bit, the two sliding grooves 12 are arranged oppositely, sliding blocks 13 are connected in the sliding grooves 12 in a sliding mode, and the mounting ring 21 is provided with a slot 211 matched with the sliding blocks 13;

an adjusting groove 14 communicated with the outside is further formed in the shell 11 along the direction perpendicular to the drill bit, an adjusting rod 15 is connected in the adjusting groove 14 in a sliding mode, and a spring 16 is connected between the adjusting rod 15 and the bottom of the adjusting groove 14;

a connecting rod 17 is connected between the adjusting rod 15 and the sliding block 13, one end of the connecting rod 17 is hinged to the adjusting rod 15, the other end of the connecting rod 17 is hinged to the sliding block 13, and in a natural state of the spring 16, one end of the adjusting rod 15, far away from the adjusting groove 14, and the sliding block 13 protrude out of the shell 11.

When the damping support 2 is installed, a user pulls out the adjusting rod 15, so that the adjusting rod 15 slides towards the inside of the adjusting groove 14 and extrudes the spring 16, meanwhile, the two sliding blocks 13 slide towards the inside of the sliding groove 12 under the linkage action of the connecting rod 17, so that the installing ring 21 is sleeved on the outer wall of the shell 11, then the inserting groove 211 in the installing ring 21 corresponds to the sliding groove 12, then the adjusting rod 15 is loosened, the spring 16 is deformed and restored, so that the adjusting rod 15 slides inwards, and the two sliding blocks 13 are driven to be inserted into the inserting groove 211 along the sliding groove 12, so that the damping support 2 is fixed, and the installation is simple and convenient;

when the damping support 2 is disassembled, a user pulls out the adjusting rod 15, so that the adjusting rod 15 slides towards the inside of the adjusting groove 14, the spring 16 is extruded, meanwhile, the two sliding blocks 13 are separated from the inserting groove 211 under the linkage action of the connecting rod 17 and slide towards the inside of the sliding groove 12, then the damping support 2 can be disassembled by pulling out the mounting ring 21, and the disassembly is simple and convenient.

Specifically, an inclined plane is arranged at one end of the sliding block 13, which is far away from the bottom of the sliding groove 12, and the inclined plane is located at one side of the sliding block 13, which is far away from the drill bit. When the damping support 2 needs to be detached by a user, the mounting ring 21 only needs to be pulled out forcefully along the axial direction of the drill bit, so that the inclined plane of the sliding block 13 is abutted to the inner wall of the sliding groove 12, the sliding block 13 is taken into the sliding groove 12 in a reverse action mode, the damping support 2 can be detached, the adjusting rod 15 does not need to be pulled out, and the use is more convenient.

Specifically, the end of the telescopic rod 22 is provided with a butting seat 23. The abutting seat 23 further increases the contact area between the telescopic rod 22 and the impact object, so that the damping support 2 is more stable to use.

Specifically, the abutting seat 23 is made of rubber. The rubber is wear-resistant, the friction force of the rubber in contact with the surface of an impact object is larger, and the stability of the impact drill is better improved.

Example two: an improved percussion drill, referring to fig. 5 to 8, the difference between the present embodiment and the first embodiment is: in this embodiment, the mounting ring 21 is screwed to the housing 11.

Specifically, the outer wall of the housing 11 is provided with a plurality of first through holes 19, and the mounting ring 21 is provided with a second through hole 212 which can be communicated with the plurality of first through holes 19; the elastic ring is characterized by further comprising an elastic ring 3, and positioning columns 31 which are correspondingly inserted into the first through holes 19 and the second through holes 212 are arranged on the inner wall of the elastic ring 3.

The installation ring 21 is easily loosened along with the vibration of the percussion drill by simply connecting the installation ring 21 on the shell in a threaded manner, so that the elastic ring 3 is arranged, the positioning column 31 is inserted into the first through hole 19 and the second through hole 212, the movement of the installation ring 21 is limited, and the looseness prevention is realized; when detaching, the positioning column 31 is pulled out, and the mounting ring 21 is twisted to be detached from the housing 11.
