[0028] This ignition needle is easy to install. Insert the bottom of the ignition needle into the mounting groove. When the edge of the fixing block contacts the inclined surface of the limiting block, the limiting block is pushed into the cavity. The limiting block compresses the spring. When the limiting groove and the limiting block are on the same horizontal line, the spring pushes the limiting block into the limiting groove, thus limiting the fixing block and fixing the ignition needle. Pulling the levers simultaneously to both sides causes the limiting blocks to move away from each other and disengage from the limiting grooves. At this point, lifting the ignition needle allows for easy and quick removal.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0040] See Figure 1-5A glue-free ceramic ignition needle includes a main body component 1, which includes: a panel 11 on which an ignition needle 12 is disposed; an installation component 2 is disposed on the panel 11 and the ignition needle 12, the installation component 2 including: an installation groove 21 formed on the top of the panel 11; a cavity 22 symmetrically formed inside the panel 11; a spring 23, one end of which is fixedly connected to the inner side wall of the cavity 22; a limiting block 24 slidably connected inside the cavity 22, the limiting block 24 having an inclined surface, the limiting block 24 being fixedly connected to the other end of the spring 23; a pull rod 25 fixedly connected to the top of the limiting block 24, the panel 11 having symmetrically formed through grooves for the pull rod 25 to move through, the pull rod 25 extending to the top of the panel 11 through the through grooves; a fixing block 26 symmetrically and fixedly connected to the outer side wall of the ignition needle 12; and a limiting groove 27 symmetrically formed on the fixing block 26. The limiting groove 27 is adapted to the shape of the limiting block 24, and the limiting groove 27 and the limiting block 24 are interference-fitted. A cleaning component 3 is provided on the ignition needle 12. The cleaning component 3 includes: a support ring 31, which is fixedly connected to the outer wall of the ignition needle 12; a housing 32, which is disposed on the top of the support ring 31; a groove 33, which is formed in the inner wall of the housing 32; and bristles 34, which are symmetrically and fixedly connected to the inner wall of the housing 32.

[0041] When the ignition needle 12 needs to be installed, the operator first passes the wire at the bottom of the ignition needle 12 through the mounting groove 21, and then inserts the bottom end of the ignition needle 12 into the mounting groove 21. When the edges of the fixing blocks 26 on both sides of the ignition needle 12 contact the inclined surfaces on the limiting blocks 24, the limiting blocks 24 are pushed into the cavity 22. The limiting blocks 24 compress the spring 23. When the bottom end of the ignition needle 12 is fully in contact with the mounting groove 21, the limiting groove 27 on the fixing block 26 and the limiting block 24 are at the same horizontal line. The spring 23, which generates elasticity after deformation, pushes the limiting block 24 into the limiting groove 27, thereby limiting the fixing block 26 and fixing the ignition needle 12. When the ignition needle 12 is damaged and needs to be removed, the operator pulls the pull rod 25 on both sides at the same time. The pull rod 25 drives the limiting blocks 24 to move away from each other and disengage from the limiting groove 27. At this time, the ignition needle 12 can be removed by lifting it up, which is relatively convenient and quick. The interference fit between the limiting groove 27 and the limiting block 24 generates significant friction and clamping force, effectively preventing relative displacement during operation and ensuring the reliability of the ignition needle 12 installation. After prolonged use, foreign matter may accumulate at the tip of the ignition needle 12. In this case, the operator places the outer casing 32 over the top of the ignition needle 12. The groove 33 on the inner side of the outer casing 32 then fits snugly against the outer wall of the support ring 31. Rotating the outer casing 32 causes the bristles 34 inside to clean the foreign matter from the tip of the ignition needle 12, preventing blockage and ensuring continued use. After cleaning, the operator removes the outer casing 32 from the support ring 31 for easy access to the ignition needle 12. Example

[0042] An auxiliary function has been added based on Embodiment 1.

[0043] See Figure 1-5 The outer wall of the outer casing 32 is provided with anti-slip texture 5. A telescopic shell 4 is fixedly connected to the inner wall of the through groove opened at the top of the panel 11 for the pull rod 25 to move, and the top end of the pull rod 25 passes through the telescopic shell 4. A slider 6 is symmetrically and fixedly connected to the outer wall of the limiting block 24, and a sliding groove 61 is symmetrically opened inside the panel 11, and the slider 6 is slidably connected in the sliding groove 61.

[0044] When the operator rotates the outer casing 32 to clean the tip of the ignition needle 12, the anti-slip texture 5 on the outside of the outer casing 32 increases the friction between the operator's hand and the outer casing 32, preventing slippage and allowing for more accurate and easier operation of the outer casing 32. When the ignition needle 12 is in normal use on the panel 11, the through slot for the pull rod 25 is blocked by the telescopic shell 4. The telescopic shell 4 prevents foreign objects from entering the cavity 22 and affecting the normal movement of the limit block 24 and the spring 23. When the operator pulls the pull rod 25 to the left, the telescopic shell 4 on the left side of the pull rod 25 retracts, and the telescopic shell 4 on the right side extends. When the spring 23 drives the pull rod 25 back to its original position, the telescopic shells 4 on both sides of the pull rod 25 return to their normal state, so that the telescopic shell 4 still blocks the through slot when the pull rod 25 moves, thereby improving the protective effect of the telescopic shell 4. When the limiting block 24 moves under the influence of the spring 23 and the pull rod 25, the sliders 6 on both sides of the limiting block 24 slide in the slide groove 61. The slide groove 61 guides the movement of the limiting block 24, thereby increasing the stability of the limiting block 24 when it moves, and making it easier for it to extend into the limiting groove 27 in a timely and accurate manner to limit the fixed block 26.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
