The utility model relates to the technical field of numerical control machine tool workpiece feeding and discharging, and discloses a numerical control machine tool workpiece feeding and discharging device which comprises a supporting frame, a lifting motor, a bearing device and a pushing device. A bearing device is arranged in the supporting frame and correspondingly connected with the interior of the supporting frame in a sliding fit mode, a pushing device is arranged at the top of the bearing device and fixedly connected with the top of the bearing device through an adaptive screw, and a bottom output shaft of the lifting motor is correspondingly connected with the bearing device in a threaded fit mode. The loading and unloading device is internally provided with the bearing device and the pushing device which cooperate with each other, so that the loading and unloading speed of large workpieces can be greatly improved, manual carrying is reduced, and the safety of the whole operation process is greatly improved.

The utility model discloses a masonry mortar spreading device for autoclaved aerated concrete porous building blocks, and belongs to the field of masonry mortar spreading. An autoclaved aerated concrete porous building block masonry mortar laying device comprises a shell, the shell is integrally formed by a bottom plate and at least two side plates, an opening is formed in the top of the shell, a transversely-extending discharging opening is formed in the bottom area of at least one side plate in the side plates, and a splitter plate is arranged on the outer wall of the shell in a sliding mode along the vertical edges of the side plates; a plurality of teeth arranged at equal intervals are arranged at the bottom edge of the splitter plate, and the distribution length of the teeth is smaller than the transverse length of the discharge port; the position height of the splitter plate can be adjusted, the mortar laying thickness of mortar can be more effectively controlled, a worker can flexibly adjust the thickness of the mortar according to actual construction requirements, the adaptability of construction is improved through the flexibility, mortar waste caused by uneven coating can be reduced, and the construction efficiency is improved. Therefore, the economic benefit of construction is improved.

The utility model relates to a rebounder technical field, and disclose a cabinet door is with rebounder with buffer effect, including the casing, the bottom of casing is connected with bottom assembly, the bottom assembly includes the base, the surface of base is opened with round groove, the surface fixed coupling of round groove has the stand, the surface of stand is equipped with the swivel joint of sleeve, the upper end fixed coupling of swivel joint has screw strip, the inner wall sliding connection of bottom assembly has sleeve joint subassembly, through setting up the hook claw, the inlet pass through groove, the outlet pass through groove, U -shaped groove, when pressing the cabinet door, push the movable column to move right, buckle the wrapping of buckle seat, and the hook claw along the side wall of Y type boss passes through the inlet pass through groove, finally stays in the turning place of Y type boss and then realizes the clamping of buckle seat through the location of hook claw, presses again, that is, can separate the locking of hook claw, spring push movable column resets and realizes the unfastening of buckle seat, this kind of mode saves time and labour, expands the utilization of space.

This utility model relates to the field of braking device technology, specifically a tow truck front wheel braking device, including a frame, a tow bar, a brake assembly, and a locking member. The frame includes a body and wheels, with the wheels rotatably mounted on the body. The tow bar is hinged to the end of the body away from the wheels. The brake assembly is mounted on the body, and the tow bar can rotate along the hinged position to engage with and drive the brake assembly to brake the wheels. The locking member is mounted on the tow bar, and after the tow bar drives the brake assembly to brake the wheels, the locking member engages with the brake assembly. By using the locking member, when the tow bar rotates along the hinge to engage with the brake assembly, the braking state can be locked, thus achieving continuous braking. Furthermore, the locking member is hinged, and rotating along the hinged position allows for rapid release of the brake.

The application discloses an electric connector for connecting electronic components, comprising a base, a first crimping member assembled on the base, the first crimping member comprising a first crimping arm and a first rotating shaft connected to the first crimping arm, the first rotating shaft being installed on the base, the first crimping member moving relative to the base between an open position and a closed position; when the first crimping member is in the open position, the axis of the first rotating shaft is in a first position, and the first crimping arm is retracted to a first lead-through part of the electronic component; when the first crimping member is in the closed position, the axis of the first rotating shaft is in a second position, the second position being offset to the first lead-through part relative to the first position, and the first crimping arm is used to press the first lead-through part. The second position is closer to the first lead-through part, the distance between the pressing position of the first crimping arm and the first lead-through part and the axis of the first rotating shaft is shortened, and according to the principle of lever, the effect of not hindering the installation or removal of the electronic component and saving labor is achieved.
