Therefore, they should not be construed as limitations on this utility model.

[0026] like Figures 1-5 As shown, this utility model provides a technical solution: an adjustable geological hammer, including a hammer head 1 for striking rocks, a hammer handle 101 for gripping and operating, and a protective sleeve that can be installed on the outer wall of the hammer handle 101 and the extension rod 302 to increase the friction between the worker gripping the hammer handle 101 and the hammer handle 101. However, the protective sleeve at the hammer handle 101 needs to have a slot reserved for operating the limiting hole 301. An assembly component 2 is set on one side of the hammer head 1 to realize the detachable connection between the hammer head 1 and the hammer handle 101. An extension component 3 is set on one side of the hammer handle 101 to realize the adjustment of the length of the hammer handle 101.

[0027] like Figure 1-5As shown, in the embodiments of this application, the extension component 3 includes a limiting hole 301, which is located on the hammer handle 101 and extends through both ends of the hammer handle 101. A fixing seat 306 is provided on the inner wall of the hammer handle 101. A fixing rod 303 is provided on one side of the fixing seat 306, and an extension rod 302 is provided on the other end of the fixing rod 303. A hook 102 is provided on one end of the extension rod 302, and a protective sleeve is fitted on its outer wall. A spring 307 is provided on the inner side of the fixing seat 306. Top posts 305 are provided at both ends of the spring 307. The top posts 305 are located in the limiting hole 301 on the hammer handle 101. A second screw 304 is provided on one end of the hammer handle 101. The second screw 304 is adapted to one end of the fixing sleeve 202. Specifically, after the hammer handle 101 is initially connected to the fixing sleeve 202 by the second screw 304, the second screw 304 is used to connect the hammer handle 101 to the fixing sleeve 202. The two screws 304, with the cooperation of bolts 201 and nuts 204, achieve a firm connection with the fixing sleeve 202. The hammer handle 101 is provided with multiple limiting holes 301, which are adapted to the top column 305. When the length of the hammer handle 101 needs to be adjusted, pressing the top column 305 will compress the spring 307, causing the top column 305 to enter the fixing seat 306. After the top column 305 enters the fixing seat 306, the operator can pull the extension rod 302. The extension rod 302, relying on the fixing rod 303, moves the fixing seat 306 horizontally, causing the top column 305 to enter the next limiting hole 301. Repeating the above operations, the length between the extension rod 302 and the hammer handle 101 can be adjusted again, thereby adjusting the length of the hammer handle 101.

[0028] like Figure 1-5As shown in the embodiment of this application, the assembly component 2 includes a first screw 203, which is located on one side of the hammer head 1 and is adapted to the other end of the fixing sleeve 202. Both the first screw 203 and the second screw 304 are provided with round holes 206, which penetrate to the upper and lower ends of the fixing sleeve 202. Support plates 205 are provided at the upper and lower ends of the fixing sleeve 202, and bolts 201 are provided inside the support plates 205. The bottom of the bolts 201... A nut 204 is provided on the outer wall. Specifically, a first screw 203 is fixedly provided on one side of the hammer head 1. The first screw 203 is threadedly connected to the fixing sleeve 202. When connecting the hammer head 1, the hammer head 1 is screwed into the fixing sleeve 202 through the first screw 203. When the first screw 203 and the fixing sleeve 202 are in full contact, the round hole 206 on the first screw 203 will coincide with the round hole 206 on the fixing sleeve 202, thereby performing initial connection of the hammer head 1. After positioning, the second screw 304 is screwed into the fixing sleeve 202, and the second screw 304 is fixedly connected to the hammer handle 101. When the second screw 304 is in full contact with the fixing sleeve 202, the round hole 206 on the second screw 304 coincides with the round hole 206 on the fixing sleeve 202, thus initially limiting the hammer handle 101. Then, the support plate 205 on the fixing sleeve 202 is inserted along the groove on the fixing sleeve 202, and the nut 204 is installed. Insert the bolt 201 into the round hole 206. After the bolt 201 contacts the nut 204, tighten the bolt 201 to make a threaded connection between the bolt 201 and the nut 204, thereby completing the assembly of the hammer head 1 and achieving a firm connection between the hammer head 1 and the fixing sleeve 202, thus making the hammer head 1 and the hammer handle 101 stably connected. When the hammer head 1 is worn and needs to be replaced, simply unscrew the bolt 201 and unscrew the first screw 203 to easily replace the new hammer head 1.

[0029] The working principle of this utility model is as follows:

[0030] First, screw the first screw 203 at one end of the hammer head 1 into the fixing sleeve 202 to ensure a tight connection. Then, screw the second screw 304 at one end of the hammer handle 101 into the fixing sleeve 202, ensuring a tight connection. Based on the slot design of the fixing sleeve 202, first insert the support plate 205, which is used to connect the bolts 201. Then, install the nut 204 in the corresponding position and insert the bolt 201 through the round hole 206. After the bolt 201 contacts the nut 204, tighten the bolt 201, thus achieving a secure connection between the hammer head 1, the hammer handle 101, and the fixing sleeve 202. When the operator needs to adjust the length of the hammer handle 101, press the top post 305. 05 compresses the spring 307, then pulls the extension rod 302. The extension rod 302 moves the fixed seat 306 through the fixed rod 303, causing the top column 305 to enter the next limiting hole 301. By operating simultaneously, the top column 305 can be adjusted to enter different limiting holes 301, thereby adjusting the length of the hammer handle 101. When the hammer head 1 is worn and needs to be replaced, use a wrench or other tools to unscrew the bolt 201, then rotate the hammer head 1 in the opposite direction to unscrew the first screw 203 from the fixed sleeve 202, remove the worn hammer head 1, screw the first screw 203 of the new hammer head 1 into the fixed sleeve 202, and then tighten it with the bolt 201 to complete the replacement of the hammer head 1.

[0031] In summary, this utility model discloses an adjustable geological hammer, including a hammer head 1, an assembly component 2, which is disposed on one side of the hammer head 1 to realize a detachable connection between the hammer head 1 and the hammer handle 101, and an extension component 3, which is disposed on one side of the hammer handle 101 to realize the adjustment of the length of the hammer handle 101. This invention allows for the initial installation of the hammer head 1 and hammer handle 101 through the threaded engagement between the first screw 203, the second screw 304, and the fixing sleeve 202. Subsequently, the hammer handle 101 and hammer head 1 are further fixed using bolts 201 and nuts 204, ensuring a secure connection between the hammer head 1, hammer handle 101, and fixing sleeve 202. This facilitates the replacement of the hammer head 1, extends the service life of the geological hammer, reduces operating costs, and minimizes resource waste. Furthermore, the combined action of the top column 305 and spring 307 allows the top column 305 to be adjusted into any limiting hole 301 by pulling the extension rod 302, thereby adjusting the distance between the extension rod 302 and the hammer handle 101, and consequently adjusting the length of the hammer handle 101. This meets diverse usage needs and improves operational comfort and work efficiency.
