At this time, the needle 205 is pinched and pulled out, which is convenient for disassembly and replacement of the needle 205 and reduces the inconvenience of disassembly and assembly due to the small size of the needle 205.

[0023] In addition, a circular groove is formed at the bottom of the stop block 202 , and the circular groove is adapted to fit the needle 205 .

[0024] like Figure 1 As shown, the mounting assembly 1 includes a push rod 101, a mounting tube 102 and a sliding block 103, wherein the mounting tube 102 is fixedly mounted at the bottom of the push rod 101, the sliding block 103 is slidably mounted in the mounting tube 102, and the fixing plate 201 is fixedly connected to the sliding block 103.

[0025] In addition, an I-shaped opening is provided at the bottom of the installation tube 102, and rectangular grooves are provided on the outer walls on both sides of the sliding block 103. The I-shaped opening is adapted to the two rectangular grooves. More specifically, when the sliding block 103 is pulled, the sliding block 103 drives the rectangular grooves to slide in the I-shaped opening, and the sliding block 103 moves downward and out of the installation tube 102, thereby facilitating the limited movement.

[0026] In addition, a pad is fixedly mounted on the top inner wall of the mounting tube 102, and a rubber plate is fixedly mounted on the bottom of the pad.

[0029] Working principle:

[0030] Step 1: Unlock and disassemble. Pull the sliding rod 302. The movement of the sliding rod 302 drives the rectangular plate 303 to move. The rectangular plate 303 slides in the installation box 301 and squeezes the spring 304. The spring 304 is squeezed and deformed to accumulate elastic force. The sliding rod 302 moves to one side of the sliding block 103 and unlocks the sliding block 103. At this time, pull the sliding block 103, the sliding block 103 moves down and moves out of the installation tube 102. At this time, the unlocking and disassembly is completed.

[0031] Step 2: Replace the needle 205. The staff member holds the sliding block 103 with one hand and pinches the conical cover 204 with the other hand and rotates the conical cover 204. The conical cover 204 rotates and twists on the stop block 202 and separates from the stop block 202. The clamping spring plate 203 loses the squeezing of the conical cover 204, releases the elastic force to reset and move away from the needle 205. The needle 205 loses the clamping and squeezing of the clamping spring plate 203. At this time, pinch the needle 205 and pull it out to replace the needle 205. Reverse the above steps to re-clamp the needle 205. At this time, the needle 205 is replaced.
