[0022] In order to make the technical means, creative features, purpose and efficacy of the utility model easy to understand, the utility model is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the utility model, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the utility model. The experimental methods in the following embodiments are conventional methods unless otherwise specified, and the materials, reagents, etc. used in the following embodiments are all commercially available unless otherwise specified.

[0023] Embodiment:

[0024] like Figure 1-4 As shown, the utility model provides an electric hammer drill with a dust collecting assembly, comprising an electric hammer drill body 1 and an electric hammer drill head 2 arranged at the end of the electric hammer drill body 1, a dust collecting assembly 3 for collecting drilling dust is arranged at the end of the electric hammer drill head 2, the dust collecting assembly 3 comprises a connecting base 31 arranged at the end of the electric hammer drill head 2, a sleeve connecting seat 32 sleeved on the outside of the connecting base 31, a plurality of groups of spring fixing seats 33 arranged on the surface of the sleeve connecting seat 32, springs 34 clamped in the spring fixing seats 33, spring end limiting rings 35 fixing the ends of a plurality of groups of springs 34, and a rubber skin 36 sleeved on the outside of the springs 34, the springs 34 cooperate with the spring end limiting rings 35 to prop up the rubber skin 36 to form a deformable dust containing space, and dust debris generated at the drilling point will fall into the dust containing space synchronously to avoid direct scattering.

[0025] The outer wall surface of the connecting base 31 and the inner wall surface of the sleeve connecting seat 32 are both ground, and the outer wall surface of the connecting base 31 and the inner wall surface of the sleeve connecting seat 32 are tightly fitted. Through the friction fit, the sleeve connecting seat 32 can be fixed to the surface of the connecting base 31 by friction, thereby facilitating the disassembly and assembly of the sleeve connecting seat 32 relative to the connecting base 31.

[0026] A cylindrical groove is provided inside the reed fixing seat 33, and one end of the reed 34 nested in the reed fixing seat 33 is cylindrical and matches the reed fixing seat 33. The reed fixing seat 33 plays a role in fixing and limiting the reed 34. Each group of reed fixing seats 33 corresponds to fixing a group of reeds 34, so that each group of reeds 34 is evenly arranged on the surface of the socket connecting seat 32, and the arranged reeds 34 can be evenly bent after the ends are pushed.

[0027] Each group of reeds 34 is designed to be arc-shaped. After being bent by force, a plurality of groups of circumferentially arranged reeds 34 push the rubber skin 36 sleeved on the outside of the reeds 34 outward to form a cylindrical internal debris collection space.

[0028] The bottom end of the spring end limiting ring 35 is provided with an annular groove, and the top end of the spring 34 is nested and fixed in the annular groove. The spring end limiting ring 35 limits the spring 34, so that the end of each group of springs 34 is kept in a fixed position, thereby ensuring that the springs 34 can bend and open synchronously after being pushed, and ensuring the stability of the opened springs 34 when bending and opening.

[0029] A skin fixing groove 4 is opened on the side of the spring end limiting ring 35, and the end of the rubber skin 36 is arc-shaped. The arc-shaped part of the end of the rubber skin 36 is sleeved in the skin fixing groove 4. After the end of the rubber skin 36 is embedded in the skin fixing groove 4, a complete sealed debris collection space can be formed. The debris entering the debris collection space from the spring end limiting ring 35 is restricted by the rubber skin 36 and will not fall out of the collection space.

[0030] The other end of the rubber skin 36 is laterally expanded outward to form an annular contact portion, which contacts the outer wall of the sleeve connection seat 32. When the rubber skin 36 is stretched open by the spring 34, the annular portion of the rubber skin 36 can fully contact the surface of the sleeve connection seat 32, thereby indirectly enhancing the connection and sealing degree between the rubber skin 36 and the sleeve connection seat 32, while facilitating the removal of the rubber skin 36 from the spring 34 and preventing the collected dust from leaking out from the connection between the sleeve connection seat 32 and the rubber skin 36.

[0031] A skin fixing elastic bandage 5 is also sleeved in the skin fixing groove 4. The diameter of the skin fixing elastic bandage 5 is consistent with the inner diameter of the skin fixing groove 4. The skin fixing elastic bandage 5 can converge the arc-shaped part of the end of the rubber skin 36 in the skin fixing groove 4, thereby ensuring the tightness of the sleeve connection between the rubber skin 36 and the skin fixing groove 4, improving the sealing of the connection, and ensuring the stable convergence of the end of the rubber skin 36 when it is stretched by the spring leaf 34.

[0032] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
