[0023] According to the present specific embodiment, the hammer handle 103 is fixedly connected to the hammer body 101 and is located on the outer side wall of the hammer body 101. The guard plate 104 is fixedly connected to the hammer body 101 and is sleeved on the outer side wall of the hammer body 101. The hammer head 102 is connected to the hammer body 101. The hammer body 101 has a groove 115. The guide rod 107 is movably connected to the hammer body 101 and inserted into the groove 115. The two ends of the buffer spring 105 are respectively fixedly connected to the guide rod 107 and the hammer body 101 and are located in the groove 115. The knocking block 106 is fixedly connected to the guide rod 107 and is located on the guide rod 107. 7 is far away from the end of the buffer spring 105. When in use, a person can knock by holding the hammer handle 103, and the hammer head 102 can be used to knock at a fixed point during knocking. After knocking, the guard plate 104 can be used for protection. After knocking, the knocking block 106 can be used for rapid knocking. When knocking, the buffer spring 105 can be used for buffering, and the hammer head 102 can be used to hit the knocking block 106 for impact, which is convenient for rapid smashing, easy to use, simple to operate, and can achieve protection with high safety. The hammer handle 103, the hammer body 101 and the knocking block 106 are all made of polymer rubber material, which increases the service life and use effect of the safety hammer.
[0024] The connecting column 108 is fixedly connected to the hammer head 102 and is located on the outer side wall of the hammer body 101. The connecting column 108 has a fixing hole 117. The hammer body 101 also has a cavity 116. The cavity 116 is L-shaped. The slider 118 is slidably connected to the hammer body 101 and is located in the cavity 116. The limiting arc block 112 is fixedly connected to the slider 118 and is located on the outer side wall of the slider 118. The limiting arc block 112 is also plugged into the fixing hole 117. The two ends of the reset spring 111 are respectively connected to the slider 118. 18 is fixedly connected to the hammer body 101 and is located in the cavity 116. The movable rod 109 is fixedly connected to the slider 118 and penetrates the hammer body 101. The pull block 110 is fixedly connected to the movable rod 109 and is located at an end of the movable rod 109 away from the slider 118. When the hammer head 102 is installed on the hammer body 101, the connecting column 108 on the hammer head 102 is inserted into the cavity 116 of the hammer body 101. The cavity 116 is L-shaped. The connecting column 108 enters the cavity 116 to The limiting arc block 112 squeezes and pushes, and then the limiting arc block 112 squeezes the movable rod 109 and the return spring 111, the movable rod 109 slides outward on the hammer body 101, and the return spring 111 is compressed. When the connecting column 108 completely enters the cavity 116, the return spring 111 recovers its deformation, the movable rod 109 is reset on the hammer body 101, and the return spring 111 pushes the limiting arc block 112 into the fixing hole 117 of the connecting column 108, so that the hammer head 102 is 01; when the hammer head 102 is replaced on the hammer body 101, the pull block 110 is pulled above the hammer body 101, and the pull block 110 drives the movable rod 109 to move outward, and the movable rod 109 drives the slider 118 to move in the cavity 116, and the limiting arc block 112 is disengaged from the fixing hole 117 of the connecting column 108, and then the hammer body 101 is separated from the hammer head 102. Through the above method, it is achieved that the hammer head 102 can be disassembled and replaced on the hammer body 101 inconveniently, thereby reducing the cost of use.
[0025] Secondly, the protective cover 113 is detachably connected to the hammer body 101 and is located outside the pulling block 110. By arranging the protective cover 113 outside the pulling block 110, the protective cover 113 is detachable from the hammer body 101, and the protective cover 113 prevents the pulling block 110 from being exposed and accidentally touched.
[0026] At the same time, the rubber pad 114 is fixedly connected to the limiting arc block 112 and is located on the outer side wall of the limiting arc block 112. By arranging the rubber pad 114 on the limiting arc block 112, the rubber pad 114 can increase the friction when the limiting arc block 112 is connected to the connecting column 108, and the limiting arc block 112 is stable in the fixing hole 117.
[0027] When in use, a person can knock by holding the hammer handle 103, and can knock at a fixed point by the hammer head 102. After knocking, the guard plate 104 can be used for protection. After knocking, the knocking block 106 can be used for rapid knocking. When knocking, the buffer spring 105 can be used for buffering. The hammer head 102 can hit the knocking block 106 for impact, which is convenient for rapid smashing, easy to use, simple to operate, and can achieve protection, with high safety.
[0028] When the hammer head 102 is installed on the hammer body 101, the connecting column 108 on the hammer head 102 is inserted into the cavity 116 of the hammer body 101, and the cavity 116 is L-shaped. The connecting column 108 enters the cavity 116 to squeeze and push the limiting arc block 112, and then the limiting arc block 112 squeezes the movable rod 109 and the reset spring 111, and the movable rod 109 slides outward on the hammer body 101, and the reset spring 111 is compressed. When the connecting column 108 completely enters the cavity 116, the reset spring 111 recovers its deformation, the movable rod 109 is reset on the hammer body 101, and the reset spring 111 pushes the limiting arc block 112 to enter the fixing hole 117 of the connecting column 108. The hammer head 102 is fastened on the hammer body 101, and finally the protective cover 113 is tightened on the outside of the hammer body 101 to cover the pull block 110 to avoid exposure. When the hammer head 102 is replaced on the hammer body 101, the protective cover 113 is first removed from the hammer body 101, and the pull block 110 is pulled above the hammer body 101, so that the pull block 110 drives the movable rod 109 to move outward, and the movable rod 109 drives the slider 118 to move in the cavity 116, and the limiting arc block 112 is disengaged from the fixing hole 117 of the connecting column 108, and then the hammer body 101 is separated from the hammer head 102. Through the above method, it is achieved that the hammer head 102 can be inconveniently disassembled and replaced on the hammer body 101, thereby reducing the use cost.
