[0032] In this embodiment, as shown in the figure, Figure 2 By matching the large end of the positioning column 4 with the large hole of the second stepped through hole 11, the straightness of the movement of the positioning column 4 can be ensured, but in this embodiment, in order to further improve the straightness of the movement of the positioning column 4, the positioning pin 6 is installed on the bottom plate 1, the positioning pin 6 is in sliding cooperation with the positioning column 4, further, the first stepped through hole 10 is formed in the positioning column 4, the diameter of the rod part of the positioning pin 6 is matched with the diameter of the first stepped through hole 10, so that during the movement of the positioning column 4, the large end thereof is matched with the large hole of the second stepped through hole 11, and the small end thereof is matched with the small hole of the first stepped through hole 10, and the compression spring 7 is sleeved on the positioning pin 6, and the top of the compression spring 7 abuts against the bottom of the first stepped through hole 10.

[0033] In this embodiment, as shown in the figure, Figure 2As shown, the bottom plate 1 is provided with mounting holes, the positioning pin 6 is a stepped column, the large end of the positioning pin 6 is fitted in the mounting hole, the bottom of the compression spring 7 abuts against the step of the positioning pin 6, so during installation, the positioning column 4 is first installed on the positioning seat 2, then the compression spring 7 is sleeved on the positioning pin 6, and finally the small hole is directly installed with the positioning seat 2, and when the small hole is installed with the positioning seat 2, the positioning pin 6 is directly fitted in the mounting hole, after installation, the compression spring 7 is compressed on the step of the first stepped hole and the step of the positioning pin 6, after the compression spring 7 is compressed, the compression spring 7 exerts an upward elastic force on the positioning column 4, so that the compression assembly is in the initial state, the positioning column 4 is in the upper stroke, and in the same way, after the external force is removed, the positioning column 4 also enters the upper stroke under the action of the compression spring 7, and the compression spring 7 also exerts a downward elastic force on the positioning pin 6, so that the positioning pin 6 does not come off the mounting hole, thereby ensuring that the positioning pin 6 does not move in the axial direction.

[0034] In this embodiment, as shown in Figure 2 The top of the positioning pin 6 is a ball head, the diameter of the ball head matches the small hole of the first stepped through hole 10, so that the top of the positioning pin 6 can smoothly enter the small hole of the first stepped through hole 10.

[0035] In this embodiment, as shown in Figure 2 The mounting hole is a stepped through hole, the large end of the positioning pin 6 matches the large end of the stepped through hole, the bottom of the small hole is provided with a through groove 12, and the small end of the stepped through hole communicates with the through groove 12. Since the positioning pin 6 and the mounting hole are in a matching relationship, air resistance is easily formed in the mounting hole, which affects the installation position of the positioning pin 6. Therefore, the mounting hole is designed as a stepped through hole, and the stepped through hole communicates with the through groove 12. When the positioning pin 6 is installed, the gas is directly discharged from the through groove 12, thereby facilitating the installation of the positioning pin 6.

[0036] In this embodiment, since the large end of the positioning column 4 matches the large hole of the second stepped through hole 11, and the positioning pin 6 matches the small hole of the first stepped through hole 10 during the downward process, the large hole of the second stepped through hole 11 is divided into two cavities by the large end of the positioning column 4. During the upward / downward process, air pressure is easily generated in the two cavities, thereby affecting the upward / downward of the positioning column 4. Therefore, as shown in Figure 1 and Figure 2 An exhaust groove 9 is formed on the outer side wall of the positioning column 4, the exhaust groove 9 communicates with the large hole of the first stepped through hole 10, so that the two cavities are communicated and connected with the outside through the exhaust groove 9, thereby making the two cavities not have air pressure difference, and not forming positive pressure and negative pressure, thereby ensuring the upward / downward of the positioning column 4.

[0037] In this embodiment, as shown inFigure 2 As shown, the positioning ring 3 and the positioning seat 2 are detachably connected by a locking screw. Preferably, the positioning seat 2 and the small hole are detachably connected by a locking screw, which makes the entire device easy to assemble and disassemble.

[0038] The working process of this utility model is as follows: First, the product sleeve is placed inside the positioning ring 3, and the positioning groove on the product sleeve is matched with the positioning protrusion 8, thereby fixing the position of the product sleeve on the circumference. Then, the housing and spring claw are placed inside the sleeve, and the housing and spring claw are based on the guide pin 5, so that the step of the guide pin 5 is located in the corresponding reference groove, thereby ensuring the relative position of the housing, spring claw, and sleeve on the circumference and avoiding inconsistency in the orientation of the spring claw, sleeve, and housing keyway during the pressing process. Finally, by applying pressure to the sleeve, the spring claw and sleeve are accurately pressed into place in one go, thereby realizing the rapid and accurate pressing between connector parts.
