[0029] To solve the problems in the background technology, such as Figures 1 to 3 As shown, the utility model proposes a simple jig for PIN needle detection, including a shell cover 2, a shell 1, a locking assembly 11 and a detection structure 12. The shell cover 2 is hinged to the shell 1, and the shell cover 2 is provided with a clamping portion. The locking assembly 11 is partially penetrated by the shell 1. The locking assembly 11 includes a pressing seat 112 protruding from the end face of the shell 1. When the shell 1 and the shell cover 2 are in a buckled state, the pressing seat 112 is clamped to the clamping portion. The pressing assembly 121 is provided on the side of the shell 1 facing the shell cover 2. The detection structure 12 includes a pressing assembly 121 and a limit seat 122. The pressing assembly 121 is elastically connected to the limit seat 122. The limit seat 122 is used to insert the PIN needle to be detected.

[0030] The locking portion 112 is provided in the shell 1, and the locking portion 112 is provided in correspondence with the locking portion on the shell cover 2. The docking portion is provided as a groove recessed in the inner wall of the shell cover 2. The locking portion 112 is provided with a press-fit seat 112. The press-fit seat 112 can be provided with two, and the press-fit seats 112 are respectively protruding on both sides of the end face of the shell 1, and the press-fit seat 112 can be passed through the inner wall of the shell 1 through the connecting column and then hinged to the shell 1. The side surface of the press-fit seat 112 is provided as a plane to correspond to the locking portion of the shell 1. When the shell cover 2 is attached to the shell 1, the side surface of the press-fit seat 112 can be abutted against the docking portion of the end face of the shell cover 2; the detection structure 12 is embedded in the inner side of the shell 1, and the detection structure The structure 12 is provided with a limit seat 122, and the limit seat 122 is embedded in the bottom end of the shell 1. The limit seat 122 is provided with a number of openings that adapt to the PIN needle for plugging and fixing the PIN needle so that the PIN needle is firmly fixed. The clamping component 121 is set as a detection seat 1211, and the detection seat 1211 covers the limit seat 122, and the detection seat 1211 is provided with a limit hole corresponding to the opening in the limit seat 122. The PIN needle can be inserted into the limit seat 122 through the detection seat 1211. When the PIN needle is tested, the PIN needle can be attached to the shell 1 through the shell cover 2 and pressed by the limit part on the detection seat 1211. After the PIN needle is pressed down, the shell cover 2 can be opened to observe the rebound height of the PIN needle, and then the rebound performance of the PIN needle can be detected.

[0031] like Figure 2 As shown, in one embodiment of the present application, the locking assembly 11 further includes a linkage member 111 , which is connected to the press-fit seat 112 and extends outside the housing 1 to disengage the press-fit seat 112 from the clamping portion.

[0032] The locking assembly 11 is understandably further provided with a linkage 111, which is arranged between the two pressing seats 112. The linkage 111 can be set as a connecting piece connected to the pressing seat 112, and the side surfaces of the two end ends of the linkage 111 are respectively pressed against the side surfaces of the pressing seat 112. When the shell 1 and the shell cover 2 are closed, the pressing seat 112 can be fastened upwards and the side surfaces of the pressing seat 112 can abut against the end surfaces of the groove portions of the shell cover 2, thereby making the shell cover 2 and the shell 1 buckled and locked. When the box cover and the box body are opened, one side of the pressing seat 112 can be lifted outward and the pressing seat 112 on one side can be pressed down by the action of the linkage 111, and the middle of the linkage 111 is connected to the shell 1 through a connecting column, so that the linkage 111 pushes up the other end with the connecting column as the axis, thereby making the pressing seat 112 open from the cover.

[0038] It can be understood that the hinged end of the shell cover 2 and the shell 1 is provided with an elastic member 3, and the elastic member 3 can be set as a spring member. The elastic member 3 is horizontally arranged at the connection between the shell cover 2 and the shell 1, and spring wires at both ends of the elastic member 3 extend out, and one end of the elastic member 3 abuts on the shell 1, and the other end of the spring member abuts on the shell cover 2. When the shell cover 2 and the shell 1 are pressed together, the spring can be squeezed so that the shell 1 and the shell cover 2 are subjected to a mutually repulsive force. When the shell cover 2 and the shell 1 are opened, the shell cover 2 and the shell 1 can be bounced open by the force on both sides of the spring, thereby facilitating the opening of the shell 1 and the shell cover 2.
