One side wall of a female end base is provided with a lock hole, the lock hole is communicated with an installation cavity, a locking piece is installed in the lock hole, the locking piece comprises a pressing part, the upper end and the lower end of the inner end face of the pressing part are respectively provided with a protruding clamping part, a clamping groove is formed between the two clamping parts, a limiting concave part is clamped in the clamping groove, and the pressing part and the limiting concave part are clamped in the clamping groove. One side wall of the female end base is further provided with a via hole, the via hole is communicated with the mounting cavity and is opposite to the lock hole, the upper side wall and the lower side wall of the via hole are provided with receding grooves, the receding grooves extend towards the lock hole, a retaining step is formed at the lock hole, the joint of the pressing part and the clamping part is provided with an elastic arm corresponding to the receding grooves, the elastic arm extends towards the pressing part, and the elastic arm is connected with the pressing part. And the elastic arm inclines towards the outer side of the pressing part. The beneficial effects of the utility model are that the locking member is provided with the clamping groove for clamping the limiting recess, so that the contact area between the locking member and the shielding assembly is large, and the locking force between the locking member and the shielding assembly is ensured.

The application discloses a folding joint, which comprises an upper joint, a lower joint, a hinge shaft, a handle body and a tightening mechanism, one end of the handle body is provided with an eccentric part; the inner side walls of the upper joint and the lower joint are respectively provided with an upper locking groove and a lower locking groove, the tightening mechanism comprises a tightening block, an adjusting screw rod and an adjusting sleeve rod, one side of the tightening block is provided with a tightening part matched with the upper locking groove and the lower locking groove, the other side is provided with a ball socket groove, one end of the adjusting screw rod is provided with a ball head part, the other end is threadedly connected with the adjusting sleeve rod, the ball head part is matched with the ball socket groove in a spherical surface, and the tightening block can be universally swung. The folding joint disclosed by the application is matched with the ball socket groove of the tightening block in a spherical surface through the ball head part of the adjusting screw rod, the universal swinging capability of the tightening block is achieved, the sufficient occlusal area and the locking strength are effectively ensured, and the locking reliability is improved.

This utility model relates to the field of float technology, specifically a highly adaptable locking structure for a through-hole float. It includes a float body with an internal channel and through holes at both ends. A fishing line is placed on the channel, and a detachable elastic silicone line is placed between the channel and the fishing line. The diameter of the elastic silicone line and the diameter of the fishing line are larger than the through holes. The silicone line wraps around the fishing line through elastic deformation, and after being secured to the fishing line, it is directly inserted into the channel. The silicone core is compressed by the channel, thus completing the installation and eliminating the need for tools. The silicone line is compressed within the limited space of the channel, forming a comprehensive wrap around the fishing line, ensuring a locking force. Even in a continuously shaking environment, the float body remains stable. The float body can be slid by forcefully pulling the fishing line by hand, completely preserving the fishing rig.

This invention discloses a hydraulic clamp with a mechanical self-locking structure and its design method, comprising: a hydraulic cylinder and a hydraulic cylinder piston rod slidably disposed within the hydraulic cylinder; a self-locking assembly is disposed on the hydraulic cylinder, the self-locking assembly including a wedge-shaped locking pin, a push rod, a push-pull locking rod, and a wedge-shaped locking block; one end of the push-pull locking rod is axially connected to the push rod, and the other end is axially connected to the hydraulic cylinder piston rod; the wedge-shaped locking pin is disposed on the outer wall of the push-pull locking rod, the wedge-shaped locking block is sleeved on the outer side of the push rod, and the inner wall of the wedge-shaped locking block is provided with a wedge-shaped groove, the wedge-shaped groove being adapted to the shape of the wedge-shaped locking pin; the wedge-shaped locking pin extends from the push-pull locking rod to the wedge-shaped locking block, and the wedge-shaped locking pin is inserted into the wedge-shaped groove; when the hydraulic cylinder is cut off, the wedge-shaped locking pin and the wedge-shaped groove of the wedge-shaped locking block form a rigid engagement, the push-pull locking rod maintains the relative position of the push rod and the hydraulic cylinder piston rod, and the whole remains locked, achieving continuous clamping, eliminating the need for continuous oil supply of electricity / fuel consumption, and reducing energy costs.
