When the metal protective cover 5 is installed, the metal protective cover 5 is downwardly sleeved with the receiving head 1, the spherical structure of the top end of the receiving head 1 can extrude the group of elastic clamping pieces 6 to be upwardly turned over, after the receiving head 1 is separated from the elastic clamping pieces 6, the elastic clamping pieces 6 can be reset and enter the inside of the annular clamping groove 3, so that the metal protective cover 5 is connected with the annular clamping groove 3. The elastic clamping piece 6 is provided with a rounded corner at one end, so that the abrasion of the wear-resistant and heat-conducting layer 4 can be reduced during assembly. The wear-resistant and heat-conducting layer 4 is made of aluminum nitride ceramic composite material. Through the above arrangement, the aluminum nitride ceramic composite material has a very high thermal conductivity, so that the heat generated by the receiving head 1 during operation can be quickly conducted away. At the same time, the material has excellent wear resistance, which can effectively resist the abrasion of the external friction on the outer surface of the receiving head 1, thereby improving the reliability and stability of the receiving head 1. Moreover, the aluminum nitride ceramic composite material has good infrared transmittance, which will not affect the normal receiving work of the receiving head 1.

[0035] Please refer to Figure 1 , Figure 3 and Figure 4 , the elastic clamping piece 6 is made of spring steel material. Through the above arrangement, the spring steel has high elasticity and strength, so that the elastic clamping piece 6 can produce sufficient elastic deformation when being extruded, and can quickly restore to the original state after the extrusion is removed, thereby ensuring the reliable connection between the metal protective cover 5 and the receiving head 1. The inside of the metal protective cover 5 is fixedly embedded with a group of heat-conducting fins 7. The cross section of the heat-conducting fin 7 is in the shape of an I-beam. The contact end of the heat-conducting fin 7 is provided with an arc shape.

[0036] Please refer to Figure 1 , Figure 4 and Figure 5 , the outer surface of the metal protective cover 5 is fixedly connected with two guide blocks 8. The inside of each guide block 8 is slidably sleeved with a lifting rod 9. The bottom end of each lifting rod 9 is fixedly connected with the same welding protective cover 10. Each pin 2 is inserted into the welding protective cover 10. Through the above arrangement, when the pin 2 needs to be welded, the protective cover is high, and the pin 2 is exposed, which is convenient for operation. After welding is completed, the welding protective cover 10 is lowered to protect the connection of the pin 2, thereby avoiding damage to the connection of the pin 2 caused by external factors. At the same time, the overall auxiliary support purpose can be achieved, thereby avoiding the inclination of the receiving head 1 caused by the bending of the pin 2.

[0038] It should be noted that before the welding protective cover 10 is lowered, the welding state of the circuit board and the pin 2 needs to be confirmed to prevent poor contact caused by false welding.

[0039] The working principle of the above embodiment is that when the metal protective cover 5 is installed, it is aligned with the receiving head 1 and is sleeved downward, the spherical structure at the top end of the receiving head 1 first contacts a set of circumferentially arranged elastic clamping pieces 6, as the metal protective cover 5 continues to press downward, the spherical structure extrudes the elastic clamping pieces 6, causing the elastic clamping pieces 6 to flip upward, when the receiving head 1 is completely inserted into the metal protective cover 5 and is out of contact with the elastic clamping pieces 6, the elastic clamping pieces 6 quickly reset by virtue of their elasticity, and the other end enters the annular clamping groove 3 at the top end of the receiving head 1, realizing reliable connection of the metal protective cover 5 and the receiving head 1, the rounded end of the elastic clamping piece 6 can effectively reduce the wear on the wear-resistant and heat-conducting layer 4 on the outer surface of the receiving head 1 during assembly, the metal protective cover 5 internally fixedly embeds a set of heat-conducting fins 7, the cross section of the heat-conducting fins 7 is in the shape of a capital I, and the contact end of the heat-conducting fins 7 is arc-shaped, which enables the heat-conducting fins 7 to more closely adhere to the receiving head 1, increases the contact area, and thus effectively improves the heat conduction efficiency, rapidly dissipating the heat generated by the receiving head 1, ensuring that the receiving head 1 always works within an appropriate temperature range and prolonging its service life, after the welding pin 2 is completed, the welding protective cover 10 is pushed downward, driving the two lifting rods 9 fixedly connected thereto to move downward in the guide block 8, a set of equidistantly arranged ratchet grooves 901 are formed on the surface of the lifting rod 9, and the top end of the guide block 8 is provided with a ratchet piece 801, the ratchet piece 801 is clamped with the ratchet groove 901, ensuring that the lifting rod 9 can only move downward, when the lifting rod 9 moves upward relative to the receiving head 1, the ratchet piece 801 interferes with the ratchet groove 901, enabling the welding protective cover 10 to stably be positioned at a position for protecting the connection of the pin 2, avoiding damage to the connection of the pin 2 caused by external factors, and simultaneously playing an auxiliary supporting role for the whole, preventing the pin 2 from being bent to cause the receiving head 1 to tilt.
