The upper and lower sliding sleeves are provided with corresponding sliding grooves along the vertical direction on their periphery, and the strike rod is provided with a pin on its periphery to extend into the sliding grooves of the upper and lower sliding sleeves and slide up and down. When the pressing component is pressed down, the upper sliding sleeve transmits the force to the striking rod via the pin, and the striking rod transmits the force to the impact component.

The upper sliding sleeve is threaded to the lower part of the main body shell through the central screw hole. An upper return spring is provided above the impact rod, and the impact rod and the upper return spring are slidably disposed in the central through hole of the lower sliding sleeve. An outer return spring is provided above the upper sliding sleeve, so that the upper end of the outer return spring abuts against the top of the peripheral light hole.

[0008] As an improvement to the above technical solution, the pressing assembly further includes a pressing handle disposed above the main body housing, and the pressing handle is threadedly connected to the main body housing from below.

[0009] As an improvement to the above technical solution, the impact assembly includes a base plate, which is threadedly connected to the lower sliding sleeve below the upper sliding sleeve. A lower return spring is provided below the upper sliding sleeve so that the lower end of the lower return spring abuts against the top end of the base plate.

[0010] As an improvement to the above technical solution, a baffle is provided on the periphery of the sliding sleeve. The baffle is flange-shaped, and the base of the baffle abuts against the upper surface of the base plate. The upper cylindrical part is slidably provided with a peripheral light hole.

[0011] As an improvement to the above technical solution, the bottom surface of the base plate is provided with several annular semicircular grooves.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are: This utility model is a coffee powder tamping hammer. When the handle is pressed, force is applied, and the main body shell transmits the force to the upper sliding sleeve through the outer return spring. The upper sliding sleeve slides down together with the impact rod in the center hole of the lower sliding sleeve, impacting the bottom plate and completing one tamping impact of coffee powder.

[0013] During the impact, the pin guides the upper sliding sleeve, the impact rod, and the lower sliding sleeve to prevent deviation. After the force is applied, the upper and lower return springs apply a restoring force to the pressing handle, the impact rod, and the pressure plate, so that the pressing handle, the impact rod, and the pressure plate are reset.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, any modifications, equivalent substitutions, improvements, etc., made by those skilled in the art to all other embodiments obtained without creative effort should be included within the protection scope of the present utility model.

[0017] Depend on Figures 1 to 4 It is understood that this utility model discloses a coffee impact hammer, including a pressing component, an impact component, and a force transmission component disposed between the pressing component and the impact component; The force transmission component includes a lower sliding sleeve 8, an upper sliding sleeve 5 disposed in the central through hole of the lower sliding sleeve 8 and capable of sliding up and down, and a strike rod 6 disposed in the central through hole of the upper sliding sleeve 5 and capable of sliding up and down; the upper sliding sleeve 5 and the lower sliding sleeve 8 are provided with corresponding sliding grooves 101 in the vertical direction on their periphery, and the strike rod 6 is provided with a pin 7 in the periphery to extend into the sliding grooves 101 of the upper sliding sleeve 5 and the lower sliding sleeve 8 and slide up and down; The pressing assembly includes at least a main body shell 2. The main body shell 2 has an observation groove 103 on its periphery and a stepped blind hole at its lower part, including a central screw hole and a peripheral smooth hole. The upper sliding sleeve 5 is threaded into the lower screw hole of the main body shell 2. An upper return spring 4 is provided above the impact rod 6, and the impact rod 6 and the upper return spring 4 are slidably disposed together in the central through hole of the lower sliding sleeve 8. An outer return spring 3 is provided above the upper sliding sleeve 5, with the upper end of the outer return spring 3 abutting against the top of the peripheral smooth hole. For ease of applying force, the smooth outer cylindrical rod of the upper sliding sleeve 5 is provided with a shoulder 105 at the connection part with the thread. In this way, when the main body shell applies force, it acts on the upper sliding sleeve 5 through the shoulder instead of through the thread, thereby protecting the thread.

[0018] When the pressing component is pressed down, the upper sliding sleeve 5 transmits force to the lower sliding sleeve 8 via the pin 7, and then to the impact component via the lower sliding sleeve 8. The lower sliding sleeve 5 has a horizontal locking groove 102 at the top of the slide groove 101, and the locking groove 1-2 communicates with the slide groove 101. The upper sliding sleeve 5 and the lower sliding sleeve 8 also have locking grooves 102 at the top of their slide grooves 101. When the handle is pressed, the upper sliding sleeve drives the impact rod to rotate into the horizontal locking groove, preventing relative sliding of the upper sliding sleeve, lower sliding sleeve, and impact rod. To unlock and reuse, simply rotate in the opposite direction.

[0019] The pressing assembly also includes a pressing handle 1 disposed on the upper part of the main housing, which is threadedly connected to the main housing 2 from below. For ease of use, the top of the pressing handle 1 is spherical, and the bottom is chamfered for easy gripping.

[0020] The impact assembly includes a base plate 11, which is threadedly connected to the lower sliding sleeve 8 below the upper sliding sleeve 8. A lower return spring 9 is provided below the upper sliding sleeve 8 so that the lower end of the lower return spring 9 abuts against the top end of the base plate 11.

[0021] The lower sleeve 8 is provided with a baffle 10 around its periphery. The baffle 10 is flange-shaped. The base of the baffle 10 abuts against the upper surface of the base plate 11. The upper cylindrical part is slidably provided with a peripheral light hole.

[0022] Pressing the handle 1 applies force, which is transmitted to the upper sliding sleeve 5 through the upper return spring 4 via the main body shell 2. The upper sliding sleeve 5 slides down together with the impact rod 6 and slides down through the center hole of the lower sliding sleeve 8, impacting the bottom plate 11 to complete one compression and impact of the coffee powder.

[0023] During the impact, the pin 7 guides the upper sliding sleeve 5, the impact rod 6, and the lower sliding sleeve 8 to prevent deviation. The upper return spring 4 provides a return force for the impact rod. The outer return spring 3 is installed between the baffle 10 and the main body shell 2 and provides a return force for the baffle 10 and the pressure plate 11 after the force is applied.
