A second drive member 22 is coupled to second table 21 and to demolition hammer assembly 3, second drive member 22 being configured to drive demolition hammer assembly 3 along a length of second table 21, for example, second drive member 22 may be a motor, an electric cylinder, an oil or air cylinder, or the like.

As shown in fig. 1 to 3, a hinge shaft 26 is connected to the second table 21 and the second moving stage 23, and the length direction of the hinge shaft 26 is disposed parallel to the first plane. The left end of the lifting component 4 is rotatably connected with the first movable table 13, the right end of the lifting component 4 is rotatably connected with the second workbench 21, and the lifting component 4 is used for driving the second workbench 21 to rotate along the circumferential direction of the hinge shaft 26 so as to adjust the angle of the second included angle. For example, the lifting assembly 4 may be an oil cylinder or an air cylinder, and the length of the oil cylinder or the air cylinder is changed to drive the second worktable 21 to rotate along the circumferential direction of the hinge shaft 26, so as to adjust the angle of the second included angle.

As shown in fig. 1, 2 and 5, the left end of the support member 5 is rotatably connected to the second movable stage 23, and the right end of the support member 5 is rotatably connected to the second table 21. Alternatively, the support assembly 5 and the lift assembly 4 are respectively provided at both sides of the second table 21 in the front-rear direction. The support base 51 is rotatably connected to the second table 21, the left end of the support rod 52 is rotatably connected to the second movable table 23, and the right end of the support rod 52 and the support base 51 are movable relative to each other. The first portion 511 is rotatably connected to the second table 21, the second portion 512 is located at the front side of the first portion 511, a channel is formed between the first portion 511 and the second portion 512, the supporting rod 52 passes through the supporting seat 51 through the channel, and after the second included angle is determined, the locking member 53 is used for adjusting the cross-sectional area of the channel to limit the relative movement between the supporting rod 52 and the supporting seat 51. For example, the locking member 53 is a bolt that is threadedly coupled to the first and second portions 511 and 512.

The crushing device of the embodiment of the invention can adjust the distance between the first part 511 and the second part 512 through the locking piece 53, thereby adjusting the size of the cross-sectional area of the channel. After the second included angle is determined, the distance between the first portion 511 and the second portion 512 can be reduced by the locking member 53, so as to limit the relative movement between the support rod 52 and the support seat 51.

In the description of the present invention, it is to be understood that the terms "central," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," "circumferential," and the like are used in the orientations and positional relationships indicated in the drawings for convenience in describing the invention and to simplify the description, and are not intended to indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and are therefore not to be considered limiting of the invention.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.

In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can, for example, be fixedly connected, detachably connected, or integrally formed; may be mechanically coupled, may be electrically coupled or may be in communication with each other; they may be directly connected or indirectly connected through intervening media, or they may be connected internally or in any other suitable relationship, unless expressly stated otherwise. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

In the present invention, unless otherwise expressly stated or limited, the first feature "on" or "under" the second feature may be directly contacting the first and second features or indirectly contacting the first and second features through an intermediate. Also, a first feature "on," "over," and "above" a second feature may be directly or diagonally above the second feature, or may simply indicate that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature may be directly under or obliquely under the first feature, or may simply mean that the first feature is at a lesser elevation than the second feature.

In the present disclosure, the terms "one embodiment," "some embodiments," "an example," "a specific example," or "some examples" and the like mean that a specific feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the present disclosure. In this specification, the schematic representations of the terms used above are not necessarily intended to refer to the same embodiment or example. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples. Furthermore, various embodiments or examples and features of different embodiments or examples described in this specification can be combined and combined by one skilled in the art without contradiction.

Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention, and that variations, modifications, substitutions and alterations can be made to the above embodiments by those of ordinary skill in the art within the scope of the present invention.
