The utility model relates to the technical field of clamps, and discloses an automobile shock absorber bracket drilling positioning clamp which comprises a bottom plate, a supporting block is fixedly installed on the outer portion of the bottom plate, a positioning groove is formed in the supporting block, an avoiding hole is formed in the supporting block, an avoiding groove is formed in the positioning groove, and a clamping groove is formed in the bottom plate. A limiting mechanism is arranged outside the bottom plate, and a material guiding mechanism is arranged outside the limiting mechanism. Through cooperation of a vacuum pump, an exhaust pipe and a rotary drum, a bracket can be adsorbed conveniently, the bracket can be tightly attached to a rubber non-slip mat conveniently, the bracket can be away from a positioning groove conveniently when a clamping plate restores to the original position, the rotary drum can rotate conveniently through cooperation of a belt wheel and a transmission belt by starting a servo motor, and therefore the bracket can be rotated and turned over conveniently; and workers do not need to turn over the bracket manually, the clamping plates are moved through repeated operation, the rotated bracket is conveniently limited, and the working efficiency is improved.

The utility model relates to the technical field of emulsion drilling machines, and discloses a motor with a handheld support, which comprises a support mechanism, a connecting ring is fixedly arranged on one side of the support mechanism, connecting blocks are fixedly arranged on two sides of the interior of the connecting ring, a hydraulic motor body is fixedly arranged on the connecting ring through the connecting blocks and bolts, and the hydraulic motor body is fixedly connected with the support mechanism. The support mechanism comprises a handheld frame and limiting clamping teeth, a rotating frame is fixedly arranged at one end of the handheld frame, an adjusting rotating shaft is fixedly arranged at one end of the rotating frame, a connecting frame is rotationally arranged outside the adjusting rotating shaft, and an adjusting pull rope is fixedly arranged at the upper end of the limiting clamping teeth. According to the utility model, the rotatable bracket mechanism is arranged inside, so that a worker can select different handheld modes and angles to improve the comfort of the drilling operation, and the drilling operation can be conveniently completed in different environments.

The invention relates to the technical field of core drill protection, in particular to a convenient-to-clean anti-jamming type core drilling coring structure which comprises a rack, a drilling mechanism is mounted on the rack, an anti-jamming structure is mounted on the drilling mechanism, an abutting mechanism is mounted on the drilling mechanism, and a cleaning mechanism is mounted on the drilling mechanism. An adjusting mechanism is mounted on the cleaning mechanism, and a flushing mechanism is mounted on the cleaning mechanism; the drilling mechanism is beneficial to drilling a rock stratum and is convenient to draw out and not easy to get stuck, the drilling mechanism is lifted and rotated to drive an anti-sticking structure to furl gravel particles towards the center, so that the gravel is not easy to get stuck, the drilling mechanism is easily lifted and drawn out, and the propping mechanism is lifted and driven by the drilling mechanism to lift and draw out the gravel particles. The abutting mechanism abuts against the underground rock stratum, and the torsion of the anti-locking structure is increased.

The utility model provides a kind of adjustable fixing device for plate-shaped workpiece trepanning, including bottom plate, the top of bottom plate is equipped with high frame, the inboard of high frame is equipped with the fixed component for clamping workpiece, the fixed component includes support ring, multiple fixed rods and multiple movable rods, the support ring is fixedly installed at the inboard center of high frame by multiple fixed rods, the movable rod is rotatably connected with the support ring by connecting piece, and pneumatic limiting mechanism is installed on the fixed rod and the movable rod.The utility model is by being provided with fixed rod, movable rod, pneumatic limiting mechanism and connecting piece, connecting piece can make movable rod flexible rotation adjustment according to the edge shape of workpiece when using, so as to facilitate the cooperation of fixed rod to carry out accurate stable clamping to irregular special-shaped workpiece at edge by the pneumatic limiting mechanism of the top of both.
