[0030] As Figures 1-4 Shown in the embodiment, the outer wall of electrode body 1 is provided with expansion part 9 near the top position, the diameter of expansion part 9 is greater than the diameter of electrode body 1, the top of expansion part 9 is attached to the bottom of protective cover 4, when protective cover 4 transmits hammering force, due to its larger contact area, can more evenly distribute hammering force to the top of electrode body 1, effectively prevent the top of electrode body 1 from being damaged due to uneven stress, at the same time, expansion part 9 is attached to the bottom of protective cover 4, enhances the connection stability between protection mechanism 3 and electrode body 1, so that protection mechanism 3 can more effectively play the role of buffering and force transmission.

[0031] As Figure 3 And Figure 5As shown, in the embodiment, the side of the electrode cap 2 is provided with a sliding groove 6, the inner wall of the protective cover 4 is fixedly provided with a magnetic sliding block 5 sliding along the inner wall of the sliding groove 6, the top of the electrode cap 2 is fixedly provided with a limiting plate 7, the side of the limiting plate 7 is slidingly connected with the side of the inner wall of the protective cover 4, when the electrode cap 2 is installed, the protective cover 4 is moved upward, the magnetic sliding block 5 moves upward along the inner wall of the sliding groove 6 and is magnetically attracted to the bottom of the limiting plate 7, thereby realizing the positioning of the protective cover 4 and preventing it from moving downward to interfere with the installation of the electrode cap 2, which facilitates the operator to use a wrench to rotate the electrode cap 2 to complete the connection and fixation with the electrode body 1, the sliding connection of the limiting plate 7 with the side of the protective cover 4 plays a guiding and limiting role on the sliding of the protective cover 4, thereby ensuring the stability of the sliding of the protective cover 4 on the electrode cap 2 and ensuring the normal work of the protection mechanism 3.

[0032] As shown in Figure 2 and Figure 3 As shown, in the embodiment, the connecting assembly 10 includes a bolt 11 fixedly provided at the bottom of the top cover 8, the top of the protective cover 4 is provided with a insertion hole 13, the bolt 11 is inserted into the insertion hole 13, the bolt 11 is inserted into the insertion hole 13, thereby realizing the connection of the top cover 8 with the protective cover 4, in the process of hammering, the bolt 11 cooperates with the insertion hole 13 to ensure the cooperative work of the top cover 8 with the protective cover 4, thereby jointly absorbing and transmitting the impact force and preventing the decrease of the protection effect due to unstable connection, thereby ensuring the effective protection of the protection mechanism 3 to the top of the electrode body 1.

[0033] As shown in Figure 2 and Figure 3 As shown, in the embodiment, the bottom of the bolt 11 is fixedly provided with a magnet block 12, the magnet block 12 is magnetically attracted to the bottom of the inner wall of the insertion hole 13, the magnetic force of the magnet block 12 makes the positioning of the bolt 11 in the insertion hole 13 more stable, thereby increasing the connection reliability of the bolt 11 with the insertion hole 13, when the top cover 8 is subjected to the hammering force, the bolt 11 can be better prevented from being accidentally pulled out, thereby ensuring the stability of the connection of the top cover 8 with the protective cover 4, thereby enabling the protection mechanism 3 to continuously and stably play the protection role in the long-term use process.

[0034] As shown in Figures 2-4 As shown, in the embodiment, the side of the top cover 8 is provided with two notched grooves 14, the two notched grooves 14 are symmetrically arranged with the vertical plane passing through the center of the top cover 8 as the symmetry plane, the operator can hold the notched groove 14 to facilitate the dismounting and mounting operation of the top cover 8, the symmetrical arrangement of the notched grooves 14 enables the operator to be more balanced when exerting force, thereby facilitating the accurate control of the movement of the top cover 8.

[0035] As shown in Figure 2As shown, in this embodiment, the top of the inner wall of the slot 14 is provided with an upper inclined surface 15, and the bottom of the inner wall of the slot 14 is provided with a lower inclined surface 16. The upper inclined surface 15 and the lower inclined surface 16 increase the size of the side opening of the slot 14, making it easier for the operator to grip the slot 14 and apply force. When disassembling the top cover 8, the inclined structure makes it easier for the operator's fingers to grip the slot 14. At the same time, the design of the upper inclined surface 15 can increase the thickness of the top cover 8 corresponding to the slot 14, preventing the top cover 8 from deforming under force at the slot 14 and extending the service life of the top cover 8.

[0036] Working principle: When installing electrode cap 2, move the protective cover 4 upward. The protective cover 4 drives the magnetic slider 5 to move upward along the inner wall of the slide groove 6 until the magnetic slider 5 is magnetically attracted to the bottom of the limiting plate 7, thereby positioning the protective cover 4 and preventing the protective cover 4 from moving downward and interfering with the installation of electrode cap 2. Then, use a wrench to rotate electrode cap 2 to achieve the connection and fixation between electrode cap 2 and the top threaded groove of electrode body 1.

[0037] When the electrode body 1 is inserted into the tunnel, the top cover 8 is hammered. The top cover 8 and the protective cover 4 will undergo slight elastic deformation when hammered. This elastic deformation can absorb part of the impact force, reduce the instantaneous impact peak transmitted to the top of the electrode body 1, and avoid the violent impact when directly hammering the top of the electrode body 1. In addition, the protective cover 4 transmits the hammering force to the expansion part 9 on the electrode body 1. Since the diameter of the expansion part 9 is larger than the diameter of the electrode body 1, and the bottom of the protective cover 4 is in contact with the top of the expansion part 9, the hammering force can be evenly distributed to the top of the electrode body 1, preventing damage to the top of the electrode body 1.

[0038] Furthermore, the hammering force is transmitted to the expansion part 9 through the protective cover 4, which avoids the hammering force being directly transmitted to the threaded connection position between the electrode cap 2 and the electrode body 1, thereby preventing the thread groove from being damaged due to excessive impact force, ensuring the stability and reliability of the connection between the electrode cap 2 and the electrode body 1, and thus ensuring that the protective mechanism 3 can stably perform its own function.

[0039] When the top cover 8 is damaged due to repeated hammering after prolonged use and needs to be replaced, the operator can hold the slot 14 and use the lower slope 16 at the bottom of the inner wall of the slot 14 to increase the size of the side opening of the slot 14. This makes it easier for the operator to hold the slot 14 and pull the top cover 8 upward. This causes the top cover 8 to move the pin 11 upward and separate it from the socket 13, thus removing the top cover 8. Then, the pin 11 at the bottom of the new top cover 8 is inserted into the socket 13 at the top of the protective cover 4. The magnet 12 at the bottom of the pin 11 is magnetically attracted to the inner wall of the socket 13, thus installing the top cover 8. The top cover 8 is easy to install and remove, making it convenient to replace the top cover 8.
