As shown in fig. 7 to 9, the stopper 233 can be pushed to rotate by a rod-shaped tool (such as a hexagonal wrench) through the operation hole 121 (the process needs to overcome the elastic force of the second elastic member 232), so that the blocking portion 2331 can be separated from the blocking surface 222, and the locking effect on the rotating member 22 can be released, at this time, the first elastic member 231 forces the rotating member 22 to rotate, so that the locking slot 221 automatically moves to be aligned with the limiting opening 111, and the second elastic member 232 forces the blocking portion 2331 to be pressed against the periphery of the rotating member 22, so as to avoid the abutment of the blocking portion 2331 with the blocking surface 222. When the end of the connecting pin 21 deviated from the fence screen 200 is inserted into the accommodating cavity 110 through the limiting opening 111 and pushes the rotating member 22 to rotate until the locking groove 221 moves to deviate from the limiting opening 111, and the connecting pin 21 slides into the locking groove 221, the resisting portion 2331 just corresponds to the resisting surface 222, at this time, the elastic potential energy of the second elastic member 232 can force the stopping member 233 to rotate, so that the resisting portion 2331 automatically moves to abut against the resisting surface 222, and locking of the connecting pin 21 can be automatically achieved. When the fence panel 200 (i.e. the connecting pin 21) needs to be disassembled, only a rod-shaped tool is needed, and the stopper 233 is pushed to rotate through the operation hole 121, so that the resisting part 2331 can be separated from the resisting surface 222, and the locking effect on the rotating piece 22 can be released; at this time, the first elastic member 231 forces the rotation member 22 to rotate, so that the locking groove 221 can automatically move to align with the limit opening 111, and the connection pin 21 can be removed, thereby removing the fence panel 200.

the fixing assembly is internally provided with a containing cavity, and a limiting opening used for communicating the containing cavity is arranged outside the fixing assembly; the connecting component comprises a connecting pin, a rotating piece and a locking mechanism; one end of the connecting pin is arranged on the side edge of the fence screen plate, the rotating piece is rotatably arranged in the accommodating cavity, and a locking groove is formed in the rotating piece; when the locking groove rotates along with the rotating piece to be aligned with the limiting opening, the other end of the connecting pin can push the rotating piece to rotate, so that the locking groove rotates along with the rotating piece to deviate from the limiting opening, and the connecting pin slides into the locking groove; the locking mechanism is arranged in the accommodating cavity and is used for limiting the rotating piece to rotate.

2. The pen connector as claimed in claim 1, wherein said rotatable member has a retaining surface thereon; the locking mechanism comprises a first elastic piece and a stop piece; the first elastic piece is arranged between the fixed component and the rotating piece, the stop piece is rotatably arranged in the accommodating cavity, and the stop piece is provided with a resisting part; when the resisting part rotates to be abutted against the resisting surface along with the stopping piece, the rotating piece can be limited to rotate; when the resisting part rotates along with the stopping part to be separated from the resisting surface, the first elastic part forces the rotating part to rotate until the locking groove is aligned with the limiting opening.

3. The pen connector of claim 2, wherein the locking mechanism further comprises a second resilient member disposed between the securing assembly and the stop member; when the connecting pin pushes the rotating piece to rotate until the connecting pin slides into the locking groove, the second elastic piece forces the stop piece to rotate, so that the resisting part is abutted against the resisting surface; the outside of fixed subassembly is equipped with and is used for the intercommunication hold the hole of chamber, the operation hole is used for the rotation operation the backstop piece, make the department of keeping out with keep out the face separation.

4. The fence coupling member as in claim 3 wherein said rotatable member has an outer arcuate surface on an outer periphery thereof for engaging said abutment surface, said stop member and said abutment being provided with an inner arcuate surface therebetween; when the resisting part is separated from the resisting surface, the inner arc surface is connected with the outer arc surface in a sliding way.

5. The pen connector of claim 3, wherein the connector assembly further comprises a first shaft and a second shaft; the rotating piece is rotatably arranged on the fixed assembly through the first rotating shaft, and a first mounting groove for mounting the first elastic piece is formed between the rotating piece and the first rotating shaft; the stop piece is rotatably installed on the fixing assembly through the second rotating shaft, and a second installation groove for installing the second elastic piece is formed between the stop piece and the second rotating shaft.

6. A pen connector as claimed in claim 3 wherein said stop member is provided with a socket at a location corresponding to said operating aperture.

7. The pen connector as claimed in any one of claims 1-6 wherein a seal is provided on the connector pin, the seal blocking the limit opening when the connector pin is slid into the locking slot.

8. The pen connector according to any one of claims 1-6, wherein the fixing assembly is an annular structure sleeved on the pen stand, at least two sides of the fixing assembly are provided with the accommodating cavity and the limit opening, and each accommodating cavity is provided with one rotating member and one locking mechanism.

9. The pen connector of any one of claims 3-6, wherein the securing assembly comprises an annular body and a cover; the annular body is sleeved on the fence upright post, at least one outer side wall of the annular body protrudes outwards to form an arch part, and the arch part is penetrated with a mounting hole for connecting a bolt or a screw; the cover body is mounted on the inner side of the annular body, the accommodating cavity is formed between the cover body and the annular body, the limiting opening is formed in the annular body, and the operation hole is formed in the cover body.
