[0031] Reference Figure 1 , Figure 2 , Figure 4The utility model provides an embodiment of a foldable geological hammer, comprising a hammer head 1, which is used for excavating and hitting hard objects. The hammer head 1 is divided into a flat head and a conical head. The lower surface of the hammer head 1 is fixedly connected to a connecting block 2, and the outer wall of the connecting block 2 is sleeved with a connecting rod 3. The upper surface of the connecting rod 3 is provided with a circular groove, and the shape and size match the connecting block 2. The top of the outer wall of the connecting rod 3 is provided with a quick-release component, and the quick-release component can quickly disassemble and install the connecting rod 3 and the connecting block 2. The bottom end of the right surface of the hammer head 1 is provided with a folding component, and the folding component can fold and store the hammer handle 51, and unfold it for use, which is convenient for carrying and using the device and enhances the practicality of the device. The folding component includes a rotating shaft 52, and the outer wall of the rotating shaft 52 is fixedly connected to the hammer handle 51, and the hammer handle 51 rotates around the center of the rotating shaft 52. The rear surface of the hammer handle 51 fits the front surface of the connecting rod 3, which can ensure the tightness of the device after storage. The inner wall of the connecting rod 3 is elastically connected to a slider 54 through a limit spring 55.
[0032] Reference Figure 1 , Figure 2 , Figure 4 The folding assembly also includes a handle 53, the right end of the handle 53 protrudes from the right surface of the connecting rod 3, and the handle 53 is convenient for grasping. The right end of the handle 53 is set to be a convex shape, and the outer wall of the convex part is provided with anti-slip grooves. A limiting groove 501 is provided on the right surface of the rotating shaft 52, and the left end of the handle 53 is matched with the limiting groove 501, and the limiting groove 501 runs through the left surface of the rotating shaft 52.
[0033] Reference Figure 1-Figure 3 The quick-release assembly includes a card block 44, a card slot 401 is provided on the front surface of the connecting block 2, the card block 44 and the card slot 401 are matched, and there are multiple groups of card blocks 44 and card slots 401, which are arranged in a circular array with the center of the connecting block 2 as the origin. The outer wall of the connecting rod 3 is fixedly connected to a fixing ring 43, and the fixing ring 43 is elastically connected to the moving ring 41 through a compression spring 42.
[0034] Reference Figure 1 , Figure 2 , Figure 4 The rotating shaft 52 passes through and is rotatably connected to the front surface of the connecting rod 3. The rotating shaft 52 is located at the bottom end of the front surface of the connecting rod 3. The slider 54 is slidably connected to the inner wall of the connecting rod 3. The slider 54 slides in the left and right directions. One end of the limit spring 55 is fixedly connected to the right surface of the slider 54, and the other end of the limit spring 55 is fixedly connected to the inner wall on the right side of the connecting rod 3. When the slider 54 moves to the right, it will squeeze the limit spring 55 to generate a reaction force.
[0035] Reference Figure 1 , Figure 2 , Figure 4There are two groups of hammer handles 51, and the two groups of hammer handles 51 are symmetrically distributed front and back with respect to the center line of the rotating shaft 52. The two groups of hammer handles 51 will rotate synchronously. The handle 53 passes through and is fixedly connected to the right surface of the slider 54. The slider 54 and the handle 53 will move synchronously. The handle 53 passes through and is slidably connected to the right surface of the connecting rod 3.
[0036] Reference Figure 1 , Figure 2 , Figure 4 The handle 53 is inserted into the inner wall of the limiting groove 501, which can limit the rotating shaft 52 to ensure that the hammer handle 51 remains stable when unfolded and stored. Every time the hammer handle 51 rotates 180°, the handle 53 will be aligned with the limiting groove 501.
[0037] Reference Figure 1-Figure 3 The block 44 passes through and is slidably connected to the front surface of the connecting rod 3. The block 44 is inserted into the inner wall of the slot 401, which can limit the connecting block 2 so that the connecting block 2 cannot be separated from the connecting rod 3. The upper surface of the block 44 is opened as an inclined surface, and the lower surface of the block 44 is opened as an inclined surface. The inclined surfaces of the lower surface and the upper surface of the block 44 are evenly distributed at the left end and the right end of the block 44. The block 44 can be moved laterally by squeezing the inclined surfaces.
[0038] Reference Figure 1-Figure 3 The movable ring 41 is slidably connected to the outer wall of the connecting rod 3 and slides longitudinally. One end of the compression spring 42 is fixedly connected to the lower surface of the movable ring 41, and the other end of the compression spring 42 is fixedly connected to the upper surface of the fixed ring 43. When the movable ring 41 moves downward, it will squeeze the compression spring 42 to generate a reaction force.
[0039] Working principle: when the geological hammer needs to be used, pull the handle 53 to the right to drive the slider 54 to move synchronously, so that the handle 53 is disengaged from the limit groove 501, and the slider 54 will squeeze the limit spring 55 to generate a reaction force. At this time, rotate the hammer handle 51 to drive the rotating shaft 52 to rotate, and release the handle 53. The reaction force of the limit spring 55 will push the slider 54 and the handle 53 to move to the left, and the left end of the handle 53 will resist the outer wall of the rotating shaft 52. When the hammer handle 51 is unfolded, the limit groove 501 will be aligned with the handle 53. Under the action of the limit spring 55, the handle 53 will be plugged into the limit groove 501 again to ensure that the hammer handle 51 is stable. When it needs to be stored, the hammer handle 51 can be folded and stored by reverse operation, which improves the convenience of carrying.
[0040] In terms of the connection between the connecting block 2 and the connecting rod 3, the fixation is achieved by the cooperation of multiple groups of card blocks 44 and the card slot 401. In the normal state, the card block 44 is inserted into the card slot 401 to fix the connecting block 2 and the connecting rod 3 to ensure that the hammer head 1 is fixed. When it needs to be disassembled, the moving ring 41 is pushed downward, and the compression spring 42 is compressed. At this time, pulling the hammer head 1 upward will drive the connecting block 2 to move upward. When the connecting block 2 moves upward, it will squeeze the inclined surface of the card block 44. After the inclined surface of the card block 44 is squeezed, it will move horizontally from the card slot. 401 is disengaged, and the limit on the connecting block 2 is released to achieve quick disassembly. During installation, the movable ring 41 is pushed downward, and the compression spring 42 is compressed to generate a reaction force. Then the connecting block 2 is inserted, and the inclined surface of the card block 44 will be squeezed, and the card block 44 will disperse and open to release the obstruction. After being inserted into place, the card block 44 will be aligned with the card slot 401. At this time, the movable ring 41 is released, and under the action of the compression spring 42, the movable ring 41 will move upward to squeeze the inclined surface of the card block 44, so that the card block 44 is inserted into the card slot 401 for fixation.
