The invention discloses a mechanical hand clamp and a mechanical hand. The mechanical hand clamp comprises a mounting base. Two drive connecting rod frames are symmetrically mounted on the mounting base, bearing blocks are mounted on the drive connecting rod frames, anti-shake mechanisms are mounted on the surfaces of the bearing blocks, through clamping grooves are formed in the side faces of thebearing blocks, and pushing mechanisms are mounted in the through clamping grooves. The equipment is provided with the anti-shake mechanisms, when the mechanical hand needs to clamp an object, the object is preliminarly fixed firstly by preliminary clamping blocks, after the object is fully clamped by the preliminary clamping blocks, pushing blocks can push away stretching fixing blocks, the clamped area of the object is increased, and even when the mechanical hand or the clamped pipeline shakes due to misoperation of a user, as the clamped area of the object is large and the object is simultaneously fixed by the preliminary clamping blocks and the stretching fixing blocks, the object cannot easily disengage from the clamp due to shaking and oscillating.

The invention relates to the field of bookracks, and particularly relates to a multifunctional bookrack. The bookrack comprises a pedestal, a support mechanism, a placement mechanism, a blocking mechanism and a braking mechanism. Via the installation of the pedestal, the support mechanism can be more stably installed, so that the support mechanism does not tilt easily; meanwhile, via the installation of the support mechanism, the placement mechanism can be used flexibly, so that books are more convenient to place and take, and placement efficiency and taking efficiency of the books are improved; meanwhile, via the installation of the braking mechanism, rotation of the placement mechanism can be conveniently controlled, so that the placement mechanism does not rotate randomly, and thus thebooks are prevented from dropping down; and the blocking mechanism is installed on one side of the support mechanism, and via the installation of the blocking mechanism, hiding or storage of the precious books is facilitated, the books are effectively prevented from being lost and damaged, and meanwhile, outside dust is effectively isolated via the blocking mechanism, and the dust is prevented from entering to damage the books.

The invention provides a mixer with a good damping effect, and relates to the technical field of industrial machinery. The mixer with the good damping effect comprises an outer box, a mixing box is arranged in the outer box, fixing plates are fixedly connected to the left and right sides of the mixing box, the centers of the tops of the fixing plates are connected with lead screws in a threaded mode through thread holes. Limiting grooves are formed in the left and right sides of the inner wall of the outer box, sliding rails are fixedly connected into the limiting grooves, and the sides, awayfrom the mixing box, of the fixing plates are movably connected with the side faces of the sliding rails. Bearings are arranged at the two ends of the bottom of the inner wall of the outer box in an inlaid mode. The mixer with the good damping effect is provided with the fixing plates, the lead screws, the limiting grooves, first groove wheels and a second groove wheel, the vibration frequency canbe changed, materials in the mixing box can be fully mixed, the materials are not prone to being left in the inner wall of the mixing box, the mixing is more even, the mixing degree of the materialsis increased, and the output of the materials is improved.

The invention discloses a convenient garbage can. The convenient garbage can has a can cover (1), a can body (2), an inner can (3) and a pedal switch (4), and is characterized in that a lock (5) is arranged below the inner can (3); the vertical movement of the inner can (3) can be controlled through the effect of the lock (5), so that an opening of a garbage bag can be loosened, users can easily take out the bag fully filled with garbage in the garbage can, and the convenient garbage can brings excellent use effect to the users.

The invention discloses a supporting device for planning of cultural activities. The supporting device comprises two bases, wherein supporting mechanisms are welded to the outer walls of the tops of the two bases; each of the supporting mechanisms comprises a supporting column; channels are arranged on the outer walls of the tops of the supporting columns in the height direction; sliding plates are mounted in the channels in a sliding manner; screw rods are connected to the outer walls of the tops of the sliding plates through bearings; limiting threaded rings are welded to the outer walls ofthe top ends of the supporting columns; limiting rings are connected to the outer walls of the top ends of the screw rods in a sleeving manner; first fixed rings are connected to the outer walls of the lower parts of the supporting columns through the bearings; a first supporting frame having an L-shaped structure is welded to the outer wall of one side of each of the first fixed rings; and secondfixed rings are connected to the outer walls, positioned above the first fixed rings, of the supporting columns through the bearings. The supporting device disclosed by the invention can be folded, so that space occupation is reduced, and the supporting device is convenient to transfer and carry; vacuum sucking discs are sucked on the ground, so that the device cannot easily fall down, and thus,a fixing effect of the device is improved.
