The utility model discloses a connecting structure of a table leg and a table, which comprises a lock rod arranged on one of the table leg and the table leg and a lock hole matched and inserted with the lock rod on the other one of the table leg and the table leg, and the lock rod is arranged in the lock hole and can move between an unlocking position and a locking position in the lock hole; one of the table legs and the table legs is rotatably connected with a cam, the other one of the table legs and the table legs is provided with a positioning hole matched with the cam in an inserted mode, the cam is rotatably switched between a first position and a second position, when the cam rotates to the first position, the convex portion of the cam extrudes the inner wall of the positioning hole so that the lock rod can move to the locking position of the lock hole, and the table legs and the table legs are locked and fixed. According to the connecting structure of the table leg and the table, the bolts do not need to be fastened or loosened through tools, assembling is easy and convenient, labor is saved, and the requirement for rapid assembling of a user can be met.

This utility model discloses an easy-to-assemble power tool, including a main unit and a working component. The main unit includes a first docking part, a first shaft locking part, and an unlocking button. The unlocking button includes a pressing part, a first peripheral locking part, and a connecting part. The working component includes a second docking part, a second shaft locking part, and a second peripheral locking part. The second peripheral locking part includes a peripheral locking groove and a sliding groove. The bottom surface of the sliding groove is set as a slope, and the height of the end of the slope away from the peripheral locking groove is lower than the height of the end near the peripheral locking groove. When the working component rotates in the forward direction around the rotation axis, the second shaft locking part gradually rotates until it is axially locked with the first shaft locking part. At the same time, the first peripheral locking part presses against the sliding groove and slides towards the top of the peripheral locking groove. In the axially locked state, the connecting part is gradually subjected to force and elastically deflected relative to the pressing part. Under the elastic restoring force of the connecting part, it springs into the peripheral locking groove and locks circumferentially with it. The working component of this power tool is easy and labor-saving to assemble, and facilitates the assembly and replacement of the working component.

The utility model discloses a kind of light high-strength welding wire disc with metal framework, including cylinder, the first clamping groove is equipped in cylinder one end, the second clamping groove is equipped in cylinder other end, there are several circular grooves between the first clamping groove and the second clamping groove, the first circular ring that size is consistent is encircled with the first clamping groove outer surface, the first circular ring is encircled with several connecting columns in cylinder one side, the second circular ring that size is consistent is encircled with the second clamping groove outer surface, the second circular ring is encircled with several fixed grooves in cylinder one side, first thread groove is equipped in the position of cylinder both ends middle, cylinder both ends are movably connected with limit disc, the middle position of limit disc is penetrated with second thread groove, the screw column that size is consistent is movably connected in second thread groove inside, limit post is equipped in screw column side, two limit disc both sides are encircled with reinforcing column, and several fixed columns are connected between reinforcing column;The utility model can enhance strength when in use.

This utility model discloses a high-pressure explosion-proof electric heater, including an electric heater housing, a water pipe connector conductively connected to the surface of the electric heater housing, support legs symmetrically welded to the bottom of the electric heater housing, an electric heating rod installed at the opening of the electric heater housing, and a mounting base fixedly connected to the end of the electric heating rod. The support legs have symmetrically opened guide holes on their surfaces, and assistive components are inserted into the surfaces of the support legs. The assistive components are inserted into the surfaces of the support legs, and guide rods are inserted through the guide holes of the support legs. Casters A and B at both ends provide auxiliary support. When assembling the electric heating rod relative to the electric heater housing, the bottom of the mounting base engages with the limiting groove of the base support. Pushing the mounting base horizontally causes casters A and B to roll relative to the ground, and the guide rods to slide relative to the support legs. This makes assembly and disassembly easier, reduces worker fatigue, and improves work efficiency.

This utility model relates to a manual press for assembling solid-phase extraction columns. It includes a manual press body, a pressure block connected to the bottom of a movable rod of the press body, and several pressure rods fixedly mounted on the bottom of the pressure block. A placement seat is provided on the base of the manual press body, and the placement seat has several placement slots for placing column tubes, each slot matching one of the pressure rods. During assembly, multiple column tubes are placed in the placement slots, and then placed one by one into the tube openings. The pressure rods of the manual press body press down on the lower and upper sieve plates. The entire solid-phase extraction column assembly can be completed on a single manual press body. The structure is simple and practical. The pressing operation of the manual press body replaces the original manual hand-held pressure rod operation, allowing for the assembly of multiple column tubes at once, saving assembly time, resulting in a tighter assembly, less effort, and higher efficiency.
