[0033] Specifically, the barrel 205 is provided with a ring table 205a, a square groove 205b, a rod groove 205c, a straight groove 205d, a threading seat 205e and a ring plate 205f, the ring table 205a is arranged on the end face of the barrel 205, the square groove 205b is partially arranged in the ring table 205a and penetrates the end face of the ring table 205a and is partially arranged in the barrel 205 and penetrates the side wall of the barrel 205, the rod groove 205c is arranged at the lower end of the square groove 205b and is in communication with the square groove 205b, the straight groove 205d is arranged on the side wall of the barrel 205 and is in communication with the rod groove 205c, the threading seat 205e is arranged on the middle part of the end face of the barrel 205, and the ring plate 205f is arranged on the side wall of the barrel 205.

[0034] Specifically, the clamping block 206 is in sliding fit with the square groove 205b, and the clamping block 206 is provided with a second spring 206a, a slot 206b and a sliding groove 206c, the second spring 206a is arranged between the clamping block 206 and the end face of the square groove 205b, the slot 206b is arranged at the lower end of the clamping block 206, and the sliding groove 206c is arranged on the side wall of the slot 206b. It is worth noting that the elastic coefficient of the second spring 206a is smaller than the elastic coefficient of the first spring 204c, in the initial state, the second spring 206a is at the original length, and the clamping block 206 partially extends out of the lower end face of the ring table 205a.

[0035] When connecting, the ring table 205a first contacts the lower end inclined surface 204h of the hook 204b, extrudes the hook 204b upward, and moves the hook 204b upward along the inclined groove 203c and moves the moving disc 204a upward through the driving rod 204d. During the moving process, due to the structure of the inclined groove 203c, the distance between the lower end of the hook 204b and the axis of the shell 203 gradually increases. When the connecting block 204e moves to the upper end of the inclined groove 203c, the ring table 205a can pass through the hook 204b and continue to move upward. When the end surface of the ring table 205a abuts against the end surface of the shell 203, the hook 204b passes over the ring table 205a, and the moving disc 204a moves downward under the action of the first spring 204c and drives the connecting block 204e to move downward along the inclined groove 203c. During the moving process, the hook 204b will contact the clamping block 206. Since the elastic coefficient of the second spring 206a is smaller than that of the first spring 204c, the hook 204b will extrude the clamping block 206 into the barrel 205.

The axial section 206f is arranged at the uppermost position, and the two ends of the inclined section 206e are connected to the radial section 206d and the axial section 206f, respectively. It is worth noting that the length of the radial section 206d is equal to the moving amplitude of the clamping block 206, and the horizontal distance between the two ends of the inclined section 206e is equal to the length of the radial section 206d.

[0037] Specifically, the unlocking piece 207 includes a third spring 207a, a moving table 207b, a connecting rod 207c, a moving rod 207d, and a convex table 207e. The moving table 207b is in sliding fit with the sidewall of the barrel 205. The third spring 207a is arranged between the moving table 207b and the end surface of the ring plate 205f.

One end of the connecting rod 207c is connected to the connecting rod 207c and is in sliding fit with the rod groove 205c. The other end extends into the slot 206b and is in sliding fit with the slot 206b. The convex table 207e is arranged on the sidewall of the connecting rod 207c and is in sliding fit with the sliding groove 206c.
